landmasses and a cold, desert-like global climate. Although the tropics during the Ice Age were still tropical, the temperate regions and sub-tropical regions were markedly different than they are today. There is a strong correlation between temperature and CO2 concentrations during this time. ...
Besides, the WO3/MoO3 and g-C3N4 had some remarkable properties, e.g., thin catalyst layer ∼2.5 mm thickness, high conductivity (103 mS/cm) and a large negative potential (- 1.1 V vs. SHE) that enhanced the charge separation, and electrocatalytic activity for H2-generation, which ...

The qualitative analysis of the products were conducted by a gas chroma- tograph equipped with a quadrupole mass spectrometer (GC-MS, Shimazu QP5050) using the same capillary columns and NMR (Bruker, AV400). The oligomerized products were analyzed by MALDI-TOF mass (Shimazu AXIMA-CFR Plus) ...
A plot of 〈Concentration〉 vs. Area was made for the 1900 strongest transitions in the spectrum (Fig. 3). It was hypothesized that transitions for the same or closely related cluster species would be grouped in the same area on this graph, which we refer to hereafter as an Intensity ...
在不同的电还原CO2路径中,CO2还原为CO(CO2+ 2H++ 2e−→ CO + H2O,-0.11 V vs RHE,双电子转移过程)是最有望先实现工业化的路径之一,因为它具有较低的过电位和高的可实现的法拉第效率(能够接近100%)。此外,气态产物CO可以很容易地收集,与H2混合用于进一步的化学过程,如甲醇生产和费托合成。

Importantly, Mauna Loa is not the only atmospheric measuring station in the world. As the graph fromNOAAshows, other stations show the same year-after-year increasingtrend. The seasonal saw-tooth varies from place to place, of course, but the backgroundtrendremains steadily upwards. The Keeling...
When assessing the parallel vs. cascade configuration, no differences are found in the total costs, climate change and fossil feedstock potential and very minor differences appear in the final product costs of polyol and DME. The lowest climate change potential is achieved in the CCUS systems becau...
Significant sensor drift occurred in the Seabird SBE 18 electrodes, which required an alternative calibration procedure, whereby it was assumed that the sensor drift was linearly proportional in time. However, this procedure did not significantly improve the data quality. It was determined that the ...
