In this study, an anatase/rutile mixed-phase titanium dioxide (TiO2) hierarchical network deposited with Au nanoparticles (Au/TiO2 ARHN) was synthesized using a facile hydrothermal method followed by a simple calcination step. Such a unique structure was designed for improving the light harvest, charge transportation/separation, and the performance of photo-electro-chemical (PEC) cells. The pro...

Copper chalcopyrite is a promising candidate for a photocathode material for photoelectrochemical (PEC) water splitting because of its high half-cell solar-to-hydrogen conversion efficiency (HC-STH), relatively simple and low-cost preparation process, and chemical stability. This paper reviews recent advances in copper chalcopyrite photocathodes. The PEC properties of copper chalcopyrite photoc...

Hydrogen, a clean energy carrier with high energy capacity, is a very promising candidate as a primary energy source for the future. Photoelectrochemical (PEC) hydrogen production from renewable biomass derivatives and water is one of the most promising approaches to producing green chemical fuel. Compared to water splitting, hydrogen production from renewable biomass derivatives and water thro...

Peritoneal exudate cells (PEC) from mice inoculated 5 to 7 days previously with 1 X 10(6) MOPC-315 plasmacytoma cells exhibit in vitro migration-inhibitory factor reactivity to soluble tumor-associated antigens. By 10 to 14 days of tumor growth, PEC from MOPC-315-bearing mice did not elicit migration-inhibitory factor when stimulated with MOPC-315 tumor-associated antigens but were still capabl...

The role of MHC products in the induction of DTH responses Ia antigens play a crucial role in these cells in the recognition of ABA determinants by lymphocytes. Second, JY-1 guinea pigs were employed as responder animals. A clear allorestriction phenomenon was observed again when weakly modified ABA-PEC were used. On the other hand, the allorestriction phenomenon was apparently abrogated when h...

Barrier films that are used on packages play an important role, especially in the protection of food products. Research is being carried out at accelerating pace to replace petroleum-based plastic films, which do not biodegrade and difficult recycle. This review article considers publications related use polyelectrolyte complexes (PECs) barrier as a strategy decrease permeation oxygen other sub...

The effects of mecillinam, trimethoprim and ciprofloxacin, antibiotics used in the treatment of urinary tract infections, on the aquatic environment were assessed. Mecillinam and ciprofloxacin were both readily biodegradable (primary degradation) in activated sludge, whereas trimethoprim persisted. The toxicity of these antibiotics towards sludge bacteria, a green alga, a cyanobacterium, a crus...

In this research, a probabilistic estimation compensation (PEC) method for fixed-width Booth multiplier is proposed. According to the probabilistic analysis for the truncation part,a formula is obtained to calculate the compensation value easily. In the application of long bit width, the PEC method is implemented by a simple compensation circuit without the exhaustive simulation to achieve a hi...
