Article history: Received 26 June 2016 Accepted 6 July 2016 Available online xxxx Degradation mechanism of foldable thin film transistors (TFTs) is investigated experimentally by electrical, mechanical and electrical–mechanical hybrid stress experiments. Mechanical and electrical stress environment was set for foldable TFTs and the degradation effect according to the applied stress is investiga...
Background: Membrane technology for water purification has gained much attention in many industries and healthier human life. Also, improving the elimination of toxic heavy metals is a needed strategy filtration public supplies. This study investigated removal from wastewater, using novel thin-film membrane. Methods: We structural, physico-chemical, antifouling properties membrane, its ability ...
Photocatalytic membranes exhibit great potential for water treatment since they combine the filtration and photo degradation in a single unit. Although blending photocatalytic nanoparticles into polymeric thin film remains the simplest method to prepare the photocatalytic membrane, the entrapped photocatalyst showed less catalytic activity due to the agglomeration and shielding effects in the p...
If a tangle, K ⊂ B, has no planar, meridional, essential surfaces in its exterior then thin position for K has no thin levels.
• Defect-free ZIF-8/GO/PIM-1 thin-film nanocomposite (TFN) membranes were fabricated. 2D ZIF/GO was produced by in situ growth of ZIF-8 on GO sheets as a continuous, uniform and thin layer. ZIF-8/GO composite results high dispersity compatibility ZG within PIM-1. PIM-1 infiltration into PVDF substrate avoided water pre-impregnation. TFN display PSI (228 kg m −2 h −1 ). In this work, film super-...
A conducting polymer-based composite material of poly(3,4-ethylenedioxythiophene) (PEDOT): poly(4-styrenesulfonate) (PSS) doped with different percentages of a room temperature ionic liquid (IL), 1-ethyl-3-methylimidazolium tetrafluoroborate ([EMIM][BF₄]), was prepared and a very small amount of the composite (2.0 µL) was drop-coated on the working area of a screen-printed carbon electrode (SPC...
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...
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...
