Within the energetic materials and additive manufacturing (AM) communities, a number of aluminum/fluoropolymer (Al/FP) combinations have been identified for their suitability in various techniques. For practical applications, such as case reactive wire or core solid propellant, range selectable reactivity within given Al/FP selection is needed. The purpose this study was to alter aluminum/polyv...

Addition of TiO2 to a polytetrafluoroethylene (PTFE) particle-dispersed composite contributes to the self-cleaning properties of the water-repellent composite. However, its application is limited to outdoor usage or under ultraviolet (UV) irradiation. In this study, a novel visible-light-sensitive photocatalytic and superhydrophobic material was developed by adding Cu/WO3 to a PTFE particulate ...

An integrated circuit (IC) dimensions continue to decrease, RC delay, crosstalk noise, and power dissipation of the interconnect structure become limiting factors for ultra-large-scale integration of integrated circuits. Modern microcircuits may have eight metal layers, each separated by only 0.1 micrometers. RC delays and cross talk rather than transistor speed are now the major performance li...

This communication reports an approach based on plasma-enhanced atomic layer deposition of aluminium oxide for the functionalization of polytetrafluoroethylene (PTFE or "Teflon") surfaces. Alternating exposure of PTFE to oxygen plasma and trimethylaluminium causes a permanent hydrophilic effect, and a more than 10-fold improvement of the "glueability" of PTFE to aluminium.

INTRODUCTION Both polyester composite (POC) and polytetrafluoroethylene (PTFE) mesh are commonly used for laparoscopic ventral hernia repair. However, sparse information exists comparing perioperative and long-term outcome by mesh repair. METHODS A prospective database was utilized to identify 116 consecutive patients who underwent laparoscopic ventral hernia repair at The Mount Sinai Hospit...

The XENON100 experiment uses 161kg of liquid xenon divided in two concentric cylinders. The inner volume is the time-projection chamber, the outer volume is the veto, and they are separated by PTFE (Teflon) panels. In the region 350nm to 1200nm, PTFE has a measured reflectivity of 99%. However, xenon emits in the UV region, and the reflectivity distribution is not sufficiently understood here. ...

The thermal conductivity of polytetrafluoroethylene (PTFE) was studied using an instrumented thermal conductivity apparatus (Lees Disk) and by DSC. The former method was used to study the effect of incorporating fillers into a PTFE/glass fiber fabric used for conveyor belts in food processing. The effect of crystallinity on thermal conductivity was investigated and different methods of crystall...

PURPOSE Infrainguinalfemoropopliteal bypass (IFPB) is recommended to peripheral arterial disease (PAD) with a long occlusion of the superficial femoral artery (SFA). The aims of our study were to determine the patency of graft materials, and identify the risk factors of graft failure. METHODS From January 1995 to April 2011, we had performed 380 IFPBs in 351 patients, including 302 femoro-abo...

BACKGROUND Healthcare workers' uniforms including surgical gowns are used as barriers to eliminate the risk of infection for both doctor and patient. The prevalence of human immunodeficiency virus, hepatitis B and C viruses in the patient population is very common. OBJECTIVES To develop antiviral surgical gown comprising of Polypropylene nonwoven as outer layer, Polytetrafluroethylene (PTFE) ...

Soft and flexible conductors are essential for the development of soft robots, wearable electronics, electronic tissue, implants. However, conventional inherently characterized by a large change in conductance upon mechanical deformation or under alternating environmental conditions, e.g., humidity, drastically limiting their application potential. This work demonstrates novel concept strain-in...
