Bacteriophages are viruses that attack bacteria. Phage therapy, a method using phages for the treatment of bacterial infectious diseases was introduced by Felix D Herelle, who co discovered phages in 1920. However , with the arrival of the the antibiotic era in the 1940 s it got suppressed, but the ongoing evolution of bacterial multidrug resistance, the potential of phage therapy is again bein...

Poly(methoxy(polyethyleneoxy)propyl-co-methacryloxypropyl) silsesquioxane membranes with different copolymer ratios were successfully fabricated via UV-induced crosslinking with mechanical stability. By selectively introducing polyethylene oxide (PEO) groups covalently bound to the ladder-structured polysilsesquioxane, we effectively suppressed the PEO crystallization, allowing for excellent CO...

Rate constants for recombination and hole transfer during oxygen evolution at illuminated α-Fe(2)O(3) electrodes were measured by intensity-modulated photocurrent spectroscopy and found to be remarkably low. Treatment of the electrode with a Co(II) solution suppressed surface recombination but did not catalyse hole transfer. Intermediates in the reaction were detected spectroscopically.

Fully epitaxial magnetic tunnel junctions (MTJs) with Co-based Heusler alloy Co(2)MnSi electrodes and a MgO tunnel barrier were fabricated with various values of Mn composition α for Co(2)Mn(α)Si in Co(2)Mn(α)Si/MgO/Co(2)Mn(α)Si MTJs. The tunnel magnetoresistance (TMR) ratios at both 4.2 K and room temperature (RT) increased systematically with increasing α in Co(2)Mn(α)Si electrodes from Mn-de...

Sequential nucleophilic substitution of phosphorus trichloride with alcohols has been achieved. Over-reaction was suppressed by rapid mixing through micro-flow technology, and asymmetric phosphotriesters containing acid- and/or base-labile functional groups were synthesized in good to high yields. Moreover, a mechanistic study using DFT calculations suggested interesting reaction pathways. More...

Ni/Co-modified aluminide coatings were prepared on Hastelloy-X superalloy by a combined process of electrodeposition and slurry aluminizing. In this regard, pure layers Ni Ni-50wt.%Co initially applied via successive aluminization was carried out technique. The microstructural chemical composition characterization the specimens revealed that compact dense coating formed with two-layered structu...
