Broadly, the content of oxygen-containing functional groups increases with the activation temperature, but the high-temperature activation in CO2 reduces the number of oxygen-containing functional groups on the surface of carbon materials [55]. Physical activation has the advantages of a simple ...
A number of new glycylcyclines were synthesized for structure-activity relationship study. Many of the derivatives exhibit potent, broad spectrum antibacterial activity against both tetracycline susceptible and resistant organisms. GAR-9...

at first. The decreasing number of valence electrons induced anti-bonding states with higher level and lower occupancy, leading to a stronger Os-H interaction. When valence electron number kept decreasing, the hydrogen adsorption strength converted to be affected by bonding state mainly near the Ferm...
Compared to larger channels, there is a substantially larger number of small channels, leading to higher surface area. Therefore, the surface potential and current density of channel7 μmis relatively low (Fig.4band Supplementary Fig.29). It should be noted that the potential and current are...

level was exceeded, ∙OH quenching by H2O2(Eq.17) outbalanced radical formation [54,55,60]. Different studies reported that MCs were degraded at higher rates compared to CYN, ANTX and BMAA because of their higher reactivity with ∙OH. This is caused by MCs’ size and higher number of...
Nitric oxide (NO) has important functions in biology and atmospheric chemistry as a toxin, signaling molecule, ozone depleting agent and the precursor of the greenhouse gas nitrous oxide (N2O). Although NO is a potent oxidant, and was available on Earth earlier than oxygen, it is unclear wheth...
Nitrogen oxides (NOx = NO + NO2) emitted from combustion and natural sources are reactive gases that regulate the composition of Earth’s atmosphere. Nocturnal oxidation driven by nitrate radicals is an important but poorly understood process in atmospheric chemistry, affecting the lifetimes...
