Abstract The low-cost, efficient photoelectrosensitive electrodes as an alternative to expensive and complex rigid systems are yet in demand for advanced photoresponsive technology. Here, the light-induced efficiency of electrochemically exfoliated TaS 2 nanosheets hydrogen generation catalysis photodetectors was demonstrated. Mutual twisting 2H-TaS flakes leads redistribution charge density in...

Great attention has been paid to green procedures and technologies for the design of environmental catalytic systems. Biomass-derived catalysts represent one greener alternatives catalysis. Photocatalytic production hydrogen peroxide (H2O2) from O2 H2O is an ideal way attracted widespread attention. Here, we show a metal-free photocatalyst cellulose, which high photocatalytic activity photoprod...

We propose a unified framework to study the walk problem in a polygonal area by two collaborative guards. A walk is conducted by the two mobile guards on the area’s boundary. They start at an initial boundary point, move along the boundary, and may possibly meet together again at an ending boundary point. It is required that the two guards maintain their mutual visibility at all times. Dependin...

A review of methods for volumetric scene reconstruction from multiple views is presented. Occupancy descriptions of the voxels in a scene volume are constructed using shape-from-silhouette techniques for binary images, and shapefrom-photo-consistency combined with visibility testing for color images.

Vahid Khakyzadeh was born in Hamedan, Iran. He received his B.S. degree (Pure Chemistry) and M.S. degree (Organic Chemistry) from Bu-Ali Sina University, Hamedan, Iran, at 2008, 2010 respectively under supervision of professor Mohammad Ali Zolfigol.

Inspired by the recent Democratic National Primary, we consider settings in which the members of a distributed population must balance their individual preferences over candidates with a requirement to quickly achieve collective unity. We formalize such settings as the “Democratic Primary Problem” (DPP) over an undirected graph, whose local structure models the social influences acting on

An efficient and convenient protocol for synthesis of 3-hydroxy-3-indolyl-2-oxindoles and 3,3-diindolyl-2-oxindoles is presented here. The syntheses were achieved selectively under catalysis of LiClO4 whereby the products were obtained purely.
