The gravitational heat conduction and the hierarchical structure in solar interior
, 2014 With the assumption of local Tsallis equilibrium, the newly defined gravitational temperature is calculated in the solar interior, whose distribution curve can be divided into three parts, the solar core region, radiation region and convection region, in

Boletín de la Sociedad Geológica Mexicana, 2015 El objetivo del este trabajo es hacer una revision sobre la distribucion del metano (CH4 ) dentro del Sistema Solar, asi como sus fuentes y sumideros en las atmosferas de sus principales cuerpos. El CH4 esta ampliamente distribuido en el Sistema Solar; en general los planetas internos son pobres en este gas, con excepcion de la Tierra, mientras que los

Advanced Functional Materials, EarlyView.By a simple anti‐Galvanic reaction, up to six copper atoms could be preferably doped into the Ag2(SR)5 staple motifs and Ag20 dodecahedral shell of an atomically precise Ag44(SR)30 nanocluster. When anatase TiO2 is used as substrate, the (AgCu)44/TiO2 photocatalyst exhibited much improved activity in photocatalytic CO2 reduction compared to Ag44/TiO2 ...

Advanced Functional Materials, EarlyView.This study explores an eco‐friendly solvent with 1,3‐dimethyl‐2‐imidazolidinone for developing perovskite ink, enhancing grain size and formation of purer phase perovskite. The inkjet‐printed perovskite solar cells demonstrated a remarkable improvement in device power conversion efficiency from 14.6% to almost 17.8%, highlighting sustainable innovation

Advanced Functional Materials, EarlyView.MXene dervied CoFe composites show increased initial Oxygen Evolution Reaction (OER) activity compared to the pure CoFe and MXene in an Anion Exchange Membrane device. Vanadium vacancies in the MXene plays a role in increased OER activity and hinders Fe leaching in the AEM device over using the pure V2C MXene as a support material for the CoFe ...
