electrolyzer for chemical fuel generation by small molecules’ electrolysis, the OER occurs at the anode (Fig.1a) [2]. Whereas, the OER proceeds on the cathode in metal–air battery (MAB in Fig.1b); its activity and stability immediately determine the charging and discharging performances of ...
Fig. 1 summarizes the building sustainability standard establishment in different countries in a timeline diagram. Fig. 2 illustrates the distribution map of leading countries in building sustainability assessment. Table 1 presents a summary of scoring methods in each standard. Different applicability of ...

Various new NFAs, which are distinct from the fused-ring ITIC and Y series NFAs, have recently been developed and utilized for iOPVs. In 2019, Liu and co-worker reported that polymer acceptors (PBN series, Fig. 7) featuring boron–nitrogen coordination (B ← N) bonds exhibited excell...
These includes Si/TiO2/ZnO and TiO2/Si as nanopillars, NiSe2/Cd0.5Zn0.5S as a type-II heterojunction, boron-doped nitrogen-deficient, carbon nitride-based Z-scheme heterostructure, NiCu phyllosilicate and organic polymer photocatalysts like g-C3N4–SrTiO3: Rh and finally Cobalt-Loaded Linear ...
The nitrogen in bio-oil exists mainly in the form of five- and six-membered heterocycles. The correlation analysis showed that the main precursors for the formation of nitrogenous heterocyclic compounds were five-membered O-heterocyclic compounds. Finally, the product distribution characteristics in...
For instance, Ohms et al. (1992) fabricated carbon-supported electrocatalysts for the ORR by using PAN as the nitrogen source, along with metal precursors such as metal sulfates (MSO4, where M=Fe, Co, Ni, Mn, Cu) and zinc chloride (ZnCl2). It was observed that under identical ...
nitrogen (ammonia, urea) excreted into the environment by aquatic animals through gills or urine (Chapter 4). Once nitrogen has been removed, the carbonskeletoncan be used either forgluconeogenesisvia oxaloacetate or be oxidized in the TCA cycle. Althoughlipogenesisoccurs mainly in the liver in ...
