The short-circuit current density of a solar cell is used as a merit function to optimize solar cell antireflection coating designs. J(sc)/J(max) ratios reach 99%, even with a 10-nm-thick passivation layer.
Anionic template method is an effective strategy in synthesizing high-nuclearity transition-lanthanide (3d-4f) heterometallic clusters. Herein, two lanthanide clusters with the formulas [Gd20Ni21(μ3-OH)21(CO3)6(IDA)21(C2H4NO2)6(C2O4)3(MoO4)1.5(μ2-OH)1.5(H2O)9]Cl10.5·79H2O (1) and [Tb20Ni21(μ3-OH)21(CO3)6(IDA)21(C2H4NO2)6(C2O4)3(MoO4)(μ2-OH)2(H2O)10]Cl11·32H2O (2) were synthesized by introducing...
Two polyoxometalate (POM)-based hybrid compounds have been successfully designed and constructed by the hydrothermal method with the molecular formula [K(H2O)2FeII/Co(H2O)2(DAPSC)]2{[FeII/Co(H2O)(DAPSC)]2[FeII/Co(H2O)4]2[Na2FeIII4P4W32O120]}·21.5H2O (1), and [Na(H2O)2FeII/Mn(H2O)2(DAPSC)]2{[FeII/Mn(H2O)(DAPSC)]2[FeII/Mn(H2O)4]2[Na2FeIII4P4W32O120(H2O)2]}·24H2O (2) (DAPSC=2,6-diacetylpyridine bis-(semicarbazone)), respectively. Structural analysis manifested...
In the field of recycling CO 2 , the photocatalytic CO 2 reduction reaction (CO 2 RR) is a typical example, and researchers have designed a variety of photocatalysts to improve the conversion rate of CO 2 over the years. In this paper, two metal−oxygen clusters are designed and formulated as [Co 3 Zn(OH) 6 (SO 4 )]• 4H 2 O (1) and [Ni 3 Zn(OH) 6 (SO 4 )]•4H 2 O (2). As for compound 1, the main structure is composed of {CoO 6 } octahedra connected by edge-sharing to form a twodimensional layer, on which {ZnO 4 } and {SO 4 } tetrahedra are supported. More interestingly, compound 1 has outstanding photocatalytic activity, which is mainly attributed to the open-framework structure and the cobalt ions as active sites. Upon catalysis for eight hours, its maximum CO generation rate is 9982.13 μmol g −1 h −1 , with a selectivity of 81.8%. Additionally, compound 1 takes on weak antiferromagnetic coupling due to Co(II) ions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
