Developing highly active and durable non-platinum catalysts for methanol oxidation is of
great significance for direct methanol fuel cells. However, their electrocatalytic efficiency is still …

Introduction SARS-CoV-2 nucleocapsid (N) protein plays a key role in multiple stages of the
viral life cycle such as viral replication and assembly. This protein is more conserved than …

CdTe thin films have been prepared by electrochemical deposition. The morphological,
structural, and optical properties of CdTe thin films deposited with different deposition time were …

Objectives During the recent wave of coronavirus disease 2019 (COVID-19) infections in
China, most individuals have been vaccinated and exposed to the omicron variant. In the …

Delafossite type oxide CuAlO 2 as a highly efficient methanol oxidation reaction catalyst support
has been investigated in this work. Utilizing the sustained release of copper from CuAlO …

In this study, Co/Zr-metal organic framework (MOF) precursors were obtained by a room-temperature
liquid-phase precipitation method and the equivalent-volume impregnation method…

Antibiotic activity can differ depending on whether the bacterial target is extracellular or
intracellular. To determine extracellular and intracellular activities of sitafloxacin (STX) against …

Nowadays, the high cost and poor durability of commercial catalyst Pt/C for methanol oxidation
reaction have impeded the further development of direct methanol fuel cells. Herein, we …

Background. Few studies reported the risk factors of fatal outcome of hospitalized patients
with coronavirus disease 2019 (COVID-19). We aimed to identify the independent risk factors …

Because constricted arc has many merits, such as high energy density and high velocity of
plasma, it is applied in many welding fields. The characteristics of constricting arc with flux …
