We consider visual category recognition in the framework of measuring similarities, or
equivalently perceptual distances, to prototype examples of categories. This approach is quite …

Hydrogen, as a clean fuel, has been considered as a promising alternative for traditional
fossil fuels in the future.[1] An enormous amount of effort has thus been made to pursue …

To make organic solar cells (OSCs) more competitive in the diverse photovoltaic cell
technologies, it is very important to demonstrate that OSCs can achieve very good efficiencies and …

Since December 2019, a newly identified coronavirus (2019 novel coronavirus, 2019-nCov)

Herein we obtained a chemically bonded TiO 2 (P25)-graphene nanocomposite photocatalyst
with graphene oxide and P25, using a facile one-step hydrothermal method. During the …

Although optical absorption is strongly associated with the physiological status of biological
tissue, existing high-resolution optical imaging modalities, including confocal microscopy 1 , …

Molybdenum disulfide (MoS 2 ) has emerged as a promising electrocatalyst for catalyzing
protons to hydrogen via the so-called hydrogen evolution reaction (HER). In order to enhance …

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a highly contagious virus
that can transmit through respiratory droplets, aerosols, or contacts. Frequent touching of …

Background There is a rapidly increasing amount of de novo genome assembly using next-generation
sequencing (NGS) short reads; however, several big challenges remain to be …

Ultrathin, lightweight, and flexible electromagnetic‐interference (EMI) shielding materials
are urgently required to manage increasingly serious radiation pollution. 2D transition‐metal …
