The finite element method is used to simulate light absorption in periodic hybrid Si nanohole (SiNH)/PEDOT:PSS arrays. The structural periodicity (P) and hole diameter (D) of the hybrid SiNH structure are varied to maximize light absorption. In terms of the solar cell performance under the AM1.5G spectrum, the highest ultimate efficiency achieved is 30.5%, when the D/P ratio is 0.8 and P is 600 nm. We have successfully fabricated the SiNH structure based on a low cost electroless chemical etching approach using a silver catalyst. The SiNH diameters formed vary from ∼200 to 300 nm, with periodicities from ∼300 to 1000 nm. The SiNH structure reveals a low average reflectance of 4% for incident light in the range 300 to 1100 nm.

In this work, a new biomass boron adsorbent of N-methyl-D-glucosamine embedded sodium alginate/polyethyleneimine/polysiloxane composite aerogel (SKPN) was reported. Relevant characterization proved that the aerogel exhibited 3D porous structure with plenty of hydroxyl and amino functional groups, which was beneficial to the diffusion of boron and the chelation between boron and SKPN. Various parameters affecting the adsorption performance including pH value, contact time initial concentration, temperature and reusability were investigated.

Reactive oxygen species exacerbate nonalcoholic steatohepatitis (NASH) by oxidizing macromolecules; yet how they promote NASH remains poorly understood. Here, we show that peroxidase activity of global hepatic peroxiredoxin (PRDX) is significantly decreased in NASH, and palmitic acid (PA) binds to PRDX1 and inhibits its peroxidase activity. Using three genetic models, we demonstrate that hepatic PRDX1 protects against NASH in male mice.

Soliton dynamics and nonlinear phenomena in quantum deformation has been investigated through conformal time differential generalized form of q deformed Sinh-Gordon equation. The underlying equation has recently undergone substantial amount of research. In Phase 1, we employed modified auxiliary and new direct extended algebraic methods.
