Supercapacitors with porous carbon structures have high energy storage capacity. However, the nature of electrode, composed mainly nanotubes (CNTs) and graphene oxide (GO) derivatives, negatively impacts volumetric electrochemical characteristics supercapacitors because poor packing density (<0.5 g cm(-3)). Herein, we report a simple method to fabricate highly dense vertically aligned reduced (VArGO) electrodes involving hand-rolling cutting processes. Because their opened-edge structure,...

Both small molecule and polymer photovoltaic cells were fabricated with molybdenum oxide interlayer at the indium tin electrode. Enhancement in power efficiencies was observed both cells. Specifically, conversion of enhanced by a maximum 38% due to significant enhancement fill factor. The improved factor is attributed reduction series resistance.

The evolution of electronic energy levels controlled air and oxygen exposed molybdenum trioxide (MoO3) films has been investigated with ultraviolet photoemission spectroscopy, inverse x-ray spectroscopy. We found that while most the as deposited MoO3 remained largely intact, reduction in work function (WF) was substantial. gradual surface WF change from 6.8 to 5.3 eV observed for film, film saturated at ∼5.7 eV. Two distinct stages exposure are observed, first dominated by adsorption...

Infrared, visible, and multispectral photodetectors are important components for sensing, security electronics applications. Current fabrication of these devices is based on inorganic materials grown by epitaxial techniques which not compatible with low‐cost large‐scale processing.

The extreme elasticity and reversible deformability of rubber, which is one the most versatile polymers in modern society, dependent on several factors, including processing conditions, curing system, types additives used. Since rubber's mechanical properties are influenced by existing structural crosslinks, their correlation with crosslink characteristics rubber was investigated using equilibrium swelling theory Flory-Rehner equation rubber-filler interaction Kraus equation.
