In this study, the transparent conducting polymer of poly (3,4-ethylenendioxythiophene): poly(styrene sulphonate) (PEDOT:PSS) was nanohybridized via inclusion of gold nanofillers including nanospheres (NSs) and nanorods (NRs). Such nanocomposite thin films offer not only more optimum conductivity than the pristine polymer but also excellent resistivity against volatile organic compounds (VOCs)....

terms and conditions of current drinking water quality standards, including reducing the maximum arsenic concentration from 50 μgl-1 to 10 μgl-1 and predicted stricter standards in future, reveals the necessity for development of new technologies. this study aimed to prepare and evaluate a new nanocomposite membrane using graphene oxide (go) thin layer to remove arsenic (v) from water. to fabri...

Durable low refractive index thin films with anti-reflection properties were successfully fabricated using chitin nanofibers (CHINF) obtained from crab shell. The low refractive index film was achieved by forming porous thin films; the porosity was produced by increasing the number of airspaces inside the membrane. The layer-by-layer (LBL) method was used to achieve the effective stacking of th...

this paper reports on preparation of polyamide membrane with addition of silver nanoparticles (agnps). agnps act as antibacterial agents that are less susceptible to membrane’s biofouling by interfacial polymerization (ip) method. agnps was synthesized via green route which has been reported previously. attenuated total reflectance-fourier transform infrared spectroscopy (atr-ftir), field emiss...

PRODUCT DESCRIPTION The AD688 is a high precision ±10 V tracking reference. Low tracking error, low initial error and low temperature drift give the AD688 reference absolute ±10 V accuracy performance previously unavailable in monolithic form. The AD688 uses a proprietary ion-implanted buried Zener diode, and laser-waferdrift-trimming of high stability thin-film resistors to provide outstanding...

In this work, the hydrophobic modification of TiO2 nanoparticles (HTiO2) was carried out by reacting with dodecylphosphonic acid (DDPA) and hexylamine solution. A facile approach of the self-assembly technique was used for the coating of hydrophobic HTiO2 layer over the microporous polypropylene (PP) membrane. The self-assembled layer was formed between the interface of trimesoyl chloride (TMC)...

A desired reflectance profile versus frequency (wavenumber) can be directly Fourier transformed into the index of refraction profile as a function of thickness which would produce the desired spectral reflectance profile. This tool has existed for some years now but does not seem to be in common use. This paper lays out some of the principles to aid in making the process more understandable, in...

The focus of this thesis is to analyze cost trends and government incentives in the California PV market during 2007-2008. The data show that pre-rebate system costs increased in California during this time period and that this was driven by a surge in worldwide module cost. Systems employing thin film technology did not exhibit a downward impact on cost, which contradicts historical and techno...

The paper describes the design, fabrication and testing of a MEMS (micro-electro-mechanical systems) variable optical attenuator (VOA) made from an organic fluoropolymer thin film. The optical attenuation is achieved by changing the radius of curvature of the organic thin film by actuating a pneumatic force. The size of the organic polymer membrane is 4 mm × 4 mm and the measured centre displac...
