Recently, flexible triboelectric nanogenerators (TENGs) have gained significant interest as a promising autonomous technology for harvesting abundant mechanical energy and powering portable electronic devices. In this work, high-performance single-electrode TENG (SETENG) is presented with highly conductive carbon cloth (CC) textile electrode an encapsulating material based on polydimethylsiloxa...

Silicone elastomer medical implants are ubiquitous in medicine, particularly for breast augmentation. However, when these devices placed within the body, disruption of natural biological interfaces occurs, which significantly changes native energy-dissipation mechanisms living systems. These new can introduce non-physiological contact pressures and tribological conditions that provoke inflammat...

Cardiac myocyte cultures usually require pharmacological intervention to prevent overproliferation of contaminating nonmyocytes. Our aim is to prevent excessive fibroblast cell proliferation without the use of cytostatins. We have produced a silicone surface with 10-microm vertical projections that we term "pegs," to which over 80% of rat neonatal cardiac fibroblasts attach within 48 h after pl...

BACKGROUND The current investigation focuses on new implant designs for increased predictability in clinically demanding situations. Microtextured implant surfaces create favorable conditions for enhanced osseointegration of dental implants compared to implants with a smooth surface, and the macroscopic implant design may influence implant stability. PURPOSE The aim of the present study was t...

Microtexturing of implant surfaces is of major relevance in the endeavor to improve biorelevant implant designs. In order to elucidate the role of biomaterial’s topography on cell physiology, obtaining quantitative correlations between cellular behavior and distinct microarchitectural properties is in great demand. Until now, the microscopically observed reorganization of the cytoskeleton on st...

Ice adhesion to superhydrophobic surfaces is most of the time studied regarding their wetting properties, in attempts predict best candidates promote low ice adhesion. However, no clear correlation between water repellency and has yet been defined, thus limiting development empirical testing. The present study puts forward a mechanical based approach (usually used for bonded joints) rationalize...

Hybrid organic-silicon heterojunction solar cells promise a significant reduction on fabrication costs by avoiding energy-intensive processes. However, their scalability remains challenging without a low-cost transparent electrode. In this work, we present solution-processed silver-nanowire meshes that uniformly cover the microtextured surface of hybrid heterojunction solar cells to enable effi...

Texturing the surface of a PDMS fi lm with microscale pillars has been shown to enhance shear adhesion to a rigid substrate by an order of magnitude when compared to untextured control fi lms. In this study, it is shown that shear load is distributed uniformly among the contacts rather than concentrated on the contacts nearest the edge of the fi lm-substrate interface, which is in contrast to t...
