Hydrated molecular anions are present in the atmosphere. Revealing structure of microsolvation is key to understanding their chemical properties. The infrared spectra CO3•−(H2O)1,2 and CO4•−(H2O)1,2 were measured via multiple photon dissociation spectroscopy both warm cold environments. Redshifted from free O–H stretch frequency, broad, structured observed stretching region for all cluster ions...

In this paper, we simultaneously determine the optimal sensor precision and observer gain, which achieves specified accuracy in state estimates. Along with unknown formulation parameterizes scaling of exogenous inputs that correspond to noise. Reciprocal is defined as precision, sparseness achieved by minimizing $l_1$ norm vector. The optimization performed constraints guaranteeing estimates, a...

Abstract Hydroplumboelsmoreite (IMA21-C), (Pb,?) 2 (W,Fe 3+ ) O 6 (H O), is a redefined elsmoreite-group mineral in the pyrochlore supergroup. It was found ‘jixianite’ cotype specimen provided by Mr. Liu Jianchang, who first 1979 Jizhou District, Tianjin City, China. The occurs as yellow to reddish brown aggregates, together with raspite and another under study. cryptocrystalline form occasiona...

In spite of the numerous advances in development H2 and O2 evolutions upon water splitting, separation from still remains a severe challenge. Herein, novel dual-functional nanocatalysts Pd/carbon nanosphere (CNS), obtained via immobilization ultrafine Pd nanoparticles onto CNS, are developed employed for both selective generation HCOOH dehydrogenation evolution H2O2 decomposition. these reactio...
