By combining nanofluids with thermally excited oscillating motion in an heat pipe (OHP), we developed ultrahigh-performance cooling device, called the nanofluid pipe. Experimental results show that when OHP is charged nanofluid, transport capability significantly increases. For example, at input power of 80.0W, diamond can reduce temperature difference between evaporator and condenser from 40.9to24.3°C. This study will accelerate development a highly efficient device for ultrahigh-heat-flux...
Significance Point-of-care thermal management (e.g., joule heating, passive cooling) shows promising applications in body temperature regulations, which can improve human comfort and reduce energy consumption. On-skin electronics with joule-heating elements have been reported. However, the research of making on-skin passive-cooling functionalities is still rare. By using multiscale porous polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene as supporting substrates, we developed...
An experimental investigation of a nanofluid oscillating heat pipe (OHP) was conducted to determine the effect on transport capability in an OHP. The consisted HPLC grade water and 1.0vol% diamond nanoparticles 5-50nm. These settle down motionless base fluid. However, motion OHP suspends working Experimental results show that significantly increased when it charged with at filling ratio 50%. It found depends operating temperature. investigated could reach thermal resistance 0.03°C∕W input...

Eur J Oral Sci 2010; 118: 510–516. © 2010 The objective of this study was to investigate the effects atmospheric gas plasmas on dentin surfaces used Extracted unerupted human third molars were prepared by removing crowns and etching exposed with 35% phosphoric acid gel. treated various periods time. molecular changes...
Abstract In this article, the plasma surface modification effects on chemical, mechanical, and biological properties of electrospun poly (ε‐caprolactone) (PCL) random nanofiber meshes (NFMs) were investigated by adjusting chemistry, that is, using glow discharges N 2 +H , NH 3 +O Ar+O gas mixtures. The property changes PCL NFMs after those treatments examined water contact angle measurements X‐ray photoelectron spectroscopy. experimental results showed introduced polar groups onto surfaces...
Abstract There is an increasing interest in recent years using novel nanomaterials as cost‐effective, sensitive, and reproducible substrate for surface‐enhanced Raman spectroscopy (SERS) applications. In this study, a SERS was developed by assembling gold nanorods into standing arrays on gold‐coated silicon slide. The nanorod were closely packed the film, generating strong electromagnetic field uniformly distributed “hot‐spots” array surface. as‐prepared substrates used to detect widely...
ABSTRACT Biofilm formation on implantable medical devices is a major impediment to the treatment of nosocomial infections and promotes local progressive tissue destruction. Staphylococcus epidermidis are leading cause biofilm indwelling devices. Bacteria in biofilms highly resistant antibiotic treatment, which combination with increasing prevalence resistance among human pathogens further complicates biofilm-related device infections. We have developed novel plasma coating technology....
Abstract This study investigated the bacterial inactivation/sterilization effects of a new atmospheric plasma source, which is brush‐shaped argon glow discharge created under 1 atm pressure. Such an brush requires extremely low power less than 20 W to operate; and therefore essentially low‐temperature as confirmed by gas‐phase temperature measurements. Two bacteria, Escherichia coli ( E. ) Micrococcus luteus M. ), seeded in various media were subjected treatment their survivability was...
Using a stainless steel mesh as template collector, electrospun nanofiber meshes with well-tailored architectures and patterns were successfully prepared from biodegradable poly (ε-caprolactone) (PCL). It was found that the resulting PCL (NF) had similar topological structures to of mesh. Such (NF meshes) improved tensile strength Young's modulus 62.7 ± 5.3 MPa, which is >40% higher than 44 5.7 MPa measured corresponding randomly oriented mats (RNF mat). On other hand, ultimate strain...
