reaction rates, device design, abundance and stability. In our demonstration of a Li-free system, we found that calcium can mediate the reduction of nitrogen for NH3synthesis. We verified the calcium-mediated process using a rigorous protocol and achieved an NH3Faradaic efficiency of 40 ± ...
2 for anode supported single cells consisting of Ni-YSZ anodes, YSZ electrolytes, and LSF-SDC cathodes. The CaO particles can greatly enhance the kinetics of oxygen reduction reaction on LSF such as improving the oxygen surface exchange coefficient at 750 °C from 1.9 × 10?5 to 54×10?5 ...
Using a durable ionic liquid-based electrolyte, this two-electron reaction is enabled by the facilitated Ca plating–stripping in the Ca metal anode at room temperature and improved CaO2/O2 redox in the air cathode. We show the proposed Ca–O2 battery is stable in air and can be made into...
Chinese researchers carried out relevant experiments in the laboratory. They successfully verified the hypothesis that calcium comes from a key breakout reaction of carbon, nitrogen and oxygen cycle (CNO cycle), revealing the origin of calcium in the star. The CJPL can greatly reduce the influence ...
A reaction scheme for the formation of the ROS on CaO2 was also proposed and discussed. Of more interest was the finding that the CaO2 which released the •OH and •O2−
Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. Removal of solidified molten material from skin requires medical assistance. Keep victim warm...
Plasma is ionized gas, which is composed of reactive oxygen (ROS) and nitrogen (RNS) species, charged particles and an optical emission also in the UV range. Plasma commonly has high temperatures, however it has become possible to produce so called cold atmospheric plasma (CAP) which has almo...
Furthermore, antimicrobial honey formulations that utilise production of ROS as the mode of action, are restricted due to the water sensitive nature of the reaction (Eq. 2). The addition of non-bound water prior to application would therefore reduce the shelf life and efficacy of the product....

The ATP-dependent 45Ca2+ uptake by inside-out PMVs (0.1-0.2 mg/mL) was measured at 37°C in a medium containing 0.1 mol/L KCl, 0.02 mol/L Tris (pH 7.4), 5 mmol/L MgCl2, 1.0 mmol/L ATP, 20 μmol/L CaCl2, and 0.015 μCi/mL 45CaCl2 [44]. The reaction was initiated by ATP...
