									<p class="isSelectedEnd">A pacemaker is a medical device used to regulate heart rhythm and maintain an adequate heart rate. It is typically implanted in the chest or abdomen and sends electrical impulses to the heart muscle through endocardial pacing leads.</p>
As pacemakers remain a widely used treatment for cardiac rhythm disorders, the quality and service life of pacing leads are critical to long-term device performance. Lead failures can create serious risks for patients and may require surgical replacement, making <a href="https://nanovea.com/friction-wear-testing-lab-services/">pacing lead insulation wear testing</a> an important part of material evaluation for implantable cardiac devices.<sup>1–5</sup>								</div>

									<p class="isSelectedEnd">The outer insulation material of an endocardial lead requires several key properties, including biological inertness, high flexibility, fracture toughness, and long service life. Low friction can reduce interaction between the lead and the blood vessel, helping minimize vessel irritation during implantation and movement.</p><p class="isSelectedEnd">Wear resistance is also critical. Endocardial leads experience continuous movement from the heart and surrounding body structures, while operating in a body-fluid environment that can influence friction, wear, and material response.</p><p>Because of this complex environment, endocardial lead insulation should be evaluated using <a href="https://nanovea.com/tribometers/">controlled tribological methods</a> that simulate relevant contact conditions. Testing in Hanks’ solution allows the friction and wear behavior of lead insulation materials to be compared under a simulated body-fluid condition rather than relying only on dry testing.</p>								</div>

The sample is moved at a controlled speed while lateral force is measured and plotted against displacement.</p><p>A stainless steel ball with a 6 mm diameter is commonly used for this type of measurement, although other counter materials, shapes, and sizes can be selected to simulate different contact conditions.

									<p class="isSelectedEnd">The nano-friction behavior of the silicone and polyether-polyurethane (PP) pacing lead materials was first evaluated using the Nano Module of the Nanovea Mechanical Tester. The coefficient of friction was measured in both dry conditions and Hanks’ solution to compare material response under ambient and simulated body-fluid environments.</p><p class="isSelectedEnd">Both materials showed significantly lower coefficient of friction in Hanks’ solution than under dry conditions. In Hanks’ solution, the silicone lead exhibited a COF of approximately 0.15, while the polyether-polyurethane lead exhibited a lower COF of approximately 0.05. Under dry conditions, the values were substantially higher, at approximately 0.6 for silicone and 0.5 for polyether-polyurethane.</p><p class="isSelectedEnd">These results demonstrate the importance of testing pacing lead insulation materials under application-relevant environmental conditions. Hanks’ solution had a strong effect on the measured friction behavior, showing that dry testing alone may not represent the tribological response of lead insulation materials in a simulated body-fluid environment.</p><p>The low-load control of the Nano Module allowed the applied force to remain constant at 50 mN during the measurement. This enabled controlled simulation of low-contact-force interaction between the lead material and surrounding biological structures.</p>								</div>

									<p class="isSelectedEnd">Wear resistance was evaluated using a Nanovea Tribometer to compare the silicone and polyether-polyurethane pacing lead materials in Hanks’ solution. After testing, the lead surfaces were examined visually and under optical microscopy to compare the extent of wear damage.</p>
<p class="isSelectedEnd">The silicone lead showed a large wear scar with a width of approximately 1.2 mm. Microscopic observation indicated severe wear on the silicone lead, with parallel deep grooves formed along the movement direction of the rubbing block.</p>
<p class="isSelectedEnd">In comparison, the polyether-polyurethane lead showed a narrower wear scar of approximately 0.6 mm. The observed wear was milder, with only several small scratches visible on the shallow surface.</p>
Wear of the lead outer insulation can contribute to pacing and sensing abnormalities, making wear resistance an important factor in endocardial lead material selection.<sup>6</sup> These results indicate that polyether-polyurethane provided lower friction and better wear resistance than silicone under the tested conditions.								</div>

									<p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">Bouldering is a demanding discipline that combines physical strength, precise body positioning, and an understanding of how the human body interacts with climbing surfaces. On slab routes, where the wall is angled below vertical and positive holds are limited or absent, a climber&#8217;s stability depends almost entirely on the tribological interaction between the body and the climbing hold surface.</p><p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">Climbing hold surface roughness plays a central role in this contact. Roughness provides the microtexture needed for smearing, a technique where high-friction rubber soles are pressed firmly against the surface to expand the effective contact area and generate adherence. A similar mechanism occurs at the fingers, where the ridges of fingerprints and the pliability of skin deform slightly against the hold&#8217;s surface features, creating grip through microscopic interlocking.</p><p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">Porosity contributes to grip performance by absorbing moisture, sweat, or chalk at the contact interface, preventing the formation of a thin lubricating film that would reduce friction. Micro-cracks and surface flaws act as additional friction points, helping the climber maintain lateral tension against the hold surface. Because these features (roughness, porosity, and surface morphology) operate at different scales and interact differently depending on the hold, quantitative <a class="underline underline underline-offset-2 decoration-1 decoration-current/40 hover:decoration-current focus:decoration-current" href="https://nanovea.com/profilometers/">3D surface measurement</a> is essential for comparing how different climbing hold textures perform under real contact conditions.</p>								</div>

									<p data-start="786" data-end="1054">Climbing holds and rock-like surfaces can include deep pores, steep asperities, sharp valleys, and irregular texture. These features are difficult to measure accurately with contact-based profilometry because a physical stylus can lose contact, deform local surface features, or fail to reach narrow cavities.</p><p data-start="786" data-end="1054">NANOVEA’s non-contact optical profilometry uses chromatic light technology to capture surface height data without touching the sample. This makes it suitable for reconstructing complex climbing hold topography, including deep nooks, pores, and surface flaws, while avoiding measurement artifacts caused by local plastic deformation.</p><p data-start="786" data-end="1054">In this study, the <a href="https://nanovea.com/instruments/jr25/">NANOVEA JR25 Optical Profiler</a> was used to measure two bouldering grips: a yellow block with a smoother, flatter surface and a green block with a rougher tactile texture. Both samples were scanned using a PS4-MG35 single-point optical sensor with a 3000 µm Z-range and a 4 µm acquisition step in X and Y.</p><p data-start="786" data-end="1054">Dual-frequency acquisition was used to reduce light sensor saturation from localized bright spots on the grip surfaces, allowing the profiler to capture roughness and pore morphology across the scanned areas.</p>								</div>

									<p>The objective of this study was to demonstrate how non-contact 3D optical profilometry can be used to reconstruct and compare the surface roughness, topography, and pore morphology of climbing holds.</p><p>Two bouldering grip samples were analyzed: a yellow hold with a smoother, flatter surface and a blue hold with a rougher tactile texture and sharper grip features. The analysis focused on surface height variation, areal roughness parameters, pore coverage, pore size, pore depth, and functional surface behavior.</p>								</div>

									<p>In this application, the NANOVEA JR25 Non-Contact Optical Profiler was used to measure the surface roughness, topography, and pore morphology of yellow and blue bouldering grip samples.</p><p>Topographic analysis showed that both grip samples had high surface roughness, with Sa values above 100 µm and Sz values above 1000 µm. Both surfaces also showed an asymmetric height distribution skewed toward valleys, indicating that recessed features played a major role in the measured surface morphology.</p><p>The yellow grip sample showed higher pore coverage, with pores covering 47.395% of the scanned surface. Its surface was mainly characterized by average-sized pores distributed across the measured area.</p><p>The blue grip sample showed lower pore coverage at 24.208%, but a much higher pore density of 31.355 particles/mm². Its pore distribution was bimodal, with a population of fine, deep pores and a separate population of larger crater-like valleys.</p><p>These results show how non-contact 3D optical profilometry can quantify climbing hold surface features that are difficult to evaluate from visual inspection alone, including roughness, pore coverage, pore depth, surface height distribution, and functional topography. The blue grip&#8217;s higher porosity and bimodal pore structure make it more likely to absorb moisture and chalk at the contact interface, while its elevated roughness and surface morphology support stable friction for shoe rubber and finger contact. The yellow grip&#8217;s lower roughness and flatter profile suggest it is better suited for use as a foothold in slab climbing, where broad surface contact matters more than deep textural engagement.</p>								</div>

This geometry presents a significant challenge for nano scratch testing, particularly for evaluating coating adhesion at the bottom of the groove.</p><p data-start="603" data-end="847">Precise positioning is critical to locate the scratch test within the groove.

The evolution of normal load and penetration depth, shown in Fig. 8, provides further insight into the progression of coating failure during testing.</p><p data-start="1110" data-end="1331">As the applied load increases, the diamond tip progressively penetrates the polymer coating, resulting in a deeper scratch track.

This difference indicates stronger adhesion of the coating in Sample 4.</p><p data-start="1518" data-end="1773">The measured critical loads enable quantitative comparison of coating adhesion performance.

									<p data-start="836" data-end="1458">The ability to accurately characterize tooth surfaces, including micro-roughness and 3D surface topography at the nanometer scale, enables advanced research and applications in orthodontics and dental materials science. Non-contact optical profilometry provides a precise method for measuring dental surface roughness and analyzing tooth surface morphology without damaging delicate structures. These measurements support the development of composite dental materials that replicate the natural surface roughness of enamel, as well as the design and fabrication of patient-specific dental casts and restorative components.</p><p data-start="1460" data-end="1982">Low surface roughness plays a primary role in limiting bacterial adhesion and plaque formation, thereby reducing the risk of cavities. An increase in average roughness (Ra) above 2 µm leads to a steep increase in biofilm formation in vivo.¹ An Ra of 0.2 µm is considered the threshold value below which no further reduction in bacterial adhesion can be expected.²</p><p data-start="1984" data-end="2182">Reconstruction of the tooth’s 3D surface topography enables the fabrication of dental casts, which are essential for accurate diagnosis, treatment planning, and the fabrication of dental appliances.</p>								</div>

									<p data-start="232" data-end="713">The present study illustrates the potential of NANOVEA’s high-precision non-contact optical profilometers for dental surface roughness measurement and 3D tooth topography analysis. Chromatic Light technology offers significant advantages over classical touch probe techniques. It acquires data points from deep crevices and complex geometries without introducing measurement errors or artifacts caused by local plastic deformation and without requiring extensive data manipulation.</p><p data-start="715" data-end="1135">Compared to focus variation systems, single-point optical sensing provides superior lateral and height accuracy, with X/Y resolution below 0.5 µm, maximum vertical resolution of 1.9 nm, and the ability to measure surface angles up to 87°. The technique is effective on transparent, opaque, specular, diffusive, polished, and rough dental surfaces, making it well suited for comprehensive dental surface characterization.</p>								</div>

									<p>Fraktografi, kırık yüzeylerdeki özelliklerin incelenmesidir ve tarihsel olarak Mikroskop veya SEM aracılığıyla araştırılmıştır. Özelliğin boyutuna bağlı olarak yüzey analizi için mikroskop (makro özellikler) veya SEM (nano ve mikro özellikler) seçilir. Her ikisi de sonuçta kırılma mekanizması tipinin tanımlanmasına olanak sağlar. Etkili olmasına rağmen, Mikroskopun açık sınırlamaları vardır ve çoğu durumda SEM, atomik seviye analizi dışında, kırılma yüzeyi ölçümü için pratik değildir ve daha geniş kullanım kapasitesinden yoksundur. Optik ölçüm teknolojisindeki gelişmeler sayesinde NANOVEA <a href="https://nanovea.com/profilometers/">3D Temassız Profilometre</a> makro ölçekli 2D ve 3D yüzey ölçümleri yoluyla nano sağlama yeteneğiyle artık tercih edilen cihaz olarak kabul ediliyor</p>								</div>

									<p>SEM'in aksine, 3D Temassız Profilometre neredeyse her yüzeyi, numune boyutunu, minimum numune hazırlığı ile ölçebilir ve tüm bunlar bir SEM'e göre üstün dikey / yatay boyutlar sunar. Bir profilometre ile nano ile makro arasındaki özellikler, numune yansıtıcılığından sıfır etkilenerek tek bir ölçümde yakalanır. Her türlü malzemeyi kolayca ölçün: şeffaf, opak, speküler, difüzif, cilalı, pürüzlü vb. 3D Temassız Profilometre, SEM maliyetinin çok altında bir maliyetle yüzey kırılma çalışmalarını en üst düzeye çıkarmak için geniş ve kullanıcı dostu bir yetenek sağlar.</p>								</div>

									<p>Bu uygulamada, NANOVEA ST400 3D Temassız Profilometrenin kırılmış bir yüzeyin tüm topografyasını (nano, mikro ve makro özellikler) nasıl hassas bir şekilde karakterize edebileceğini gösterdik. 3D alandan yüzey net bir şekilde tanımlanabilir ve alt alanlar veya profiller / kesitler hızlı bir şekilde çıkarılabilir ve sonsuz bir yüzey hesaplamaları listesi ile analiz edilebilir. Nanometre altı yüzey özellikleri, entegre bir AFM modülü ile daha fazla analiz edilebilir.</p><p>Ayrıca NANOVEA, Profilometre serisine, özellikle kırık yüzeyinin taşınamaz olduğu saha çalışmaları için kritik olan taşınabilir bir versiyon eklemiştir. Bu geniş yüzey ölçüm yetenekleri listesiyle, kırık yüzey analizi tek bir cihazla hiç bu kadar kolay ve kullanışlı olmamıştı.</p>								</div>

									<p>Kayış tahrikli bir makinedeki kayışlar için sürtünme ve aşınma kaçınılmazdır. Yeterli sürtünme kayma olmadan etkili güç aktarımı sağlar, ancak aşırı sürtünme kayışı hızla aşındırabilir. Kayışla tahrik işlemi sırasında yorulma, aşınma ve sürtünme gibi farklı aşınma türleri meydana gelir. Kayışın ömrünü uzatmak ve kayış onarımı ve değişiminde maliyeti ve zamanı azaltmak için, kayışların aşınma performansının güvenilir bir şekilde değerlendirilmesi, kayış ömrünü, üretim verimliliğini ve uygulama performansını iyileştirmek için arzu edilir. Kayışın sürtünme katsayısının ve aşınma oranının doğru ölçümü, Ar-Ge'yi ve kayış üretiminin kalite kontrolünü kolaylaştırır.</p>								</div>

COF'nin kademeli olarak arttığı alıştırma döneminden sonra, Dokulu Kayışın 10 N ve 100 N yükler kullanılarak yapılan her iki testte de ~0,5'lik daha düşük bir COF'ye ulaşması ilginçtir. 10 N yük altında test edilen Düz Kayış, COF sabitlendiğinde ~1,4'lük önemli ölçüde daha yüksek bir COF sergilemekte ve testin geri kalanında bu değerin üzerinde kalmaktadır. Düz Kayış 100 N yük altında test edildiğinde çelik 440 bilye tarafından hızla aşındırılmış ve büyük bir aşınma izi oluşturmuştur. Bu nedenle test 220 devirde durdurulmuştur.</span></p>								</div>

									<p class="MsoNormal">3D aşınma izi profili, TABLO 1'de gösterildiği gibi gelişmiş analiz yazılımı tarafından hesaplanan aşınma izi hacminin doğrudan ve doğru bir şekilde belirlenmesini sağlar. Düz Kayış, 220 devirlik bir aşınma testinde 75,7 mm3 hacmiyle çok daha büyük ve derin bir aşınma izine sahipken, 600 devirlik bir aşınma testinden sonra Dokulu Kayış için aşınma hacmi 14,0 mm3'tür. Düz Kayışın çelik bilyeye karşı önemli ölçüde daha yüksek sürtünmesi, Dokulu Kayışa kıyasla 15 kat daha yüksek bir aşınma oranına yol açmaktadır.</p><p class="MsoNormal"> </p><p class="MsoNormal">Dokulu Kayış ile Düz Kayış arasındaki bu kadar ciddi bir COF farkı muhtemelen kayış ile çelik bilye arasındaki temas alanının boyutuyla ilgilidir ve bu da farklı aşınma performanslarına yol açmaktadır. ŞEKİL 3, iki kayışın optik mikroskop altındaki aşınma izlerini göstermektedir. Aşınma izi incelemesi, COF evrimine ilişkin gözlemle uyumludur: 0,5 gibi düşük bir COF değerini koruyan Dokulu Kayış, 10 N yük altındaki aşınma testinden sonra hiçbir aşınma belirtisi göstermez. 10 N'de Düz Kayış küçük bir aşınma izi gösterir. 100 N'de gerçekleştirilen aşınma testleri, hem Dokulu hem de Düz Kayışlarda önemli ölçüde daha büyük aşınma izleri oluşturur ve aşınma oranı, aşağıdaki paragrafta tartışılacağı gibi 3D profiller kullanılarak hesaplanacaktır.</p>								</div>

									<p>Bu çalışmada, NANOVEA T2000 Tribometre'nin kayışların sürtünme katsayısını ve aşınma oranını iyi kontrollü ve nicel bir şekilde değerlendirme kapasitesini sergiledik. Yüzey dokusu, hizmet performansları sırasında kayışların sürtünme ve aşınma direncinde kritik bir rol oynamaktadır. Dokulu kayış, ~0,5'lik sabit bir sürtünme katsayısı sergiler ve uzun bir kullanım ömrüne sahiptir, bu da takım onarımı veya değişimi için daha az zaman ve maliyet sağlar. Buna karşılık, düz kayışın çelik bilyeye karşı aşırı sürtünmesi kayışı hızla aşındırır. Ayrıca, kayış üzerindeki yükleme, hizmet ömrü açısından hayati bir faktördür. Aşırı yük çok yüksek sürtünme yaratarak kayışın daha hızlı aşınmasına neden olur.</p>
<p>NANOVEA T2000 Tribometre, ISO ve ASTM uyumlu rotatif ve lineer modları kullanarak hassas ve tekrarlanabilir aşınma ve sürtünme testleri sunar ve isteğe bağlı yüksek sıcaklık aşınması, yağlama ve tribokorozyon modülleri önceden entegre edilmiş tek bir sistemde mevcuttur.&nbsp;<span style="font-size: 16.8px;">NANOVEA'nın&nbsp;</span>eşsiz ürün yelpazesi, ince veya kalın, yumuşak veya sert kaplamaların, filmlerin ve alt tabakaların tüm tribolojik özelliklerini belirlemek için ideal bir çözümdür.</p>								</div>

									<p>Fosiller, eski denizlerin, göllerin ve nehirlerin altındaki tortulara gömülmüş bitki, hayvan ve diğer organizmaların izlerinin korunmuş kalıntılarıdır. Yumuşak vücut dokusu genellikle ölümden sonra çürür, ancak sert kabuklar, kemikler ve dişler fosilleşir. Orijinal kabukların ve kemiklerin mineral değişimi gerçekleştiğinde mikroyapı yüzey özellikleri genellikle korunur, bu da havanın evrimi ve fosillerin oluşum mekanizması hakkında bir fikir verir.</p>								</div>

									<p>Fosilin 3 boyutlu profilleri, fosil örneğinin detaylı yüzey özelliklerini daha yakından gözlemlememizi sağlıyor. NANOVEA profilometrenin yüksek çözünürlüğü ve doğruluğu çıplak gözle fark edilemeyebilir. Profilometrenin analiz yazılımı bu benzersiz yüzeylere uygulanabilen geniş bir çalışma yelpazesi sunar. NANOVEA, dokunmalı problar gibi diğer tekniklerin aksine <a href="https://nanovea.com/profilometers/">3D Temassız Profilometre</a> Numuneye dokunmadan yüzey özelliklerini ölçer. Bu, bazı hassas fosil örneklerinin gerçek yüzey özelliklerinin korunmasına olanak tanır. Ayrıca taşınabilir model Jr25 profilometre, fosil alanlarında 3 boyutlu ölçüm yapılmasına olanak tanır ve bu da fosil analizini ve kazı sonrası korumayı büyük ölçüde kolaylaştırır.</p>								</div>

Cihazın fosil örneklerinin 3D morfolojisini hassas bir şekilde karakterize edebildiğini gösterdik. Örneklerin ilginç yüzey özellikleri ve dokuları daha sonra analiz edilmektedir. Brachiopod örneği farklı bir oluk dokusuna sahipken, Crinoid kök fosili tercihli doku izotropisi göstermektedir.

									<p>Yüzey özelliklerinin, desenlerin, şekillerin vb. arayüzünün oryantasyon için değerlendirildiği çalışmalarda, ölçüm profilinin tamamı üzerinde ilgilenilen alanları hızlı bir şekilde belirlemek faydalı olacaktır. Kullanıcı, bir yüzeyi önemli alanlara bölerek, incelenen tüm yüzey profilindeki işlevsel rollerini anlamak için sınırları, tepeleri, çukurları, alanları, hacimleri ve diğerlerini hızlı bir şekilde değerlendirebilir. Örneğin, metallerin tane sınırı görüntülemesinde olduğu gibi, analizin önemi birçok yapının arayüzü ve bunların genel yönelimidir. Her bir ilgi alanının anlaşılmasıyla, genel alan içindeki kusurlar ve / veya anormallikler tanımlanabilir. Tane sınırı görüntüleme tipik olarak Profilometre kapasitesini aşan bir aralıkta çalışılmasına ve yalnızca 2D görüntü analizi olmasına rağmen, burada gösterilecek olan kavramı 3D yüzey ölçüm avantajlarıyla birlikte daha büyük ölçekte göstermek için yararlı bir referanstır.</p>								</div>

									Bu uygulamada, NANOVEA 3D Temassız Optik Profiler'ın lastik diş derinliğini, kontur boyutlarını ve kauçuk yüzey pürüzlülüğünü nasıl hassas bir şekilde karakterize edebildiğini gösterdik. Veriler, 2,69 µm'lik bir yüzey pürüzlülüğü ve 9 mm²'lik bir yansıtma alanına sahip 9,41 mm²'lik bir gelişmiş alan göstermektedir. Kauçuk dişlerin çeşitli boyutları ve yarıçapları da ölçülmüştür. Bu bilgiler, lastik üreticileri, otomotiv araştırmacıları ve malzeme mühendisleri tarafından lastik sırt tasarımlarını, kauçuk formülasyonlarını veya farklı aşınma derecelerine sahip lastikleri karşılaştırmak için kullanılabilir. Burada gösterilen veriler, Ultra 3D analiz yazılımında bulunan hesaplamaların sadece bir kısmını temsil etmektedir.								</div>
