Cationic Phosphino Beryllium Scorpionates and their Reactivity as Lewis Acid–Base Pairs

open access: yesChemistryEurope, EarlyView.
Monocationic tris(pyrazolyl)borate beryllium phosphine complexes are synthesized and characterized. These compounds readily react with substrates like CO2, SO2, H2, O2, S8, and Se8. Therefore, the nature of the BeP bond is also analyzed computationally. Herein, the article describes a facile and modular access to cationic beryllium phosphine complexes

Mesoporous Silica‐Based Photocatalytic Materials for Solar Energy Storage and Utilization

open access: yesCarbon Energy, EarlyView.
ABSTRACT The efficient storage and application of sustainable solar energy has drawn significant attention from both academic and industrial points of view. However, most developed catalytic materials still suffer from insufficient mass diffusion and unsatisfactory durability due to the lack of interconnected and regulatable porosity.

Heterogeneous Interface Engineering of CoMoP/C3N4/N‐Doped Carbon to Boost Overall Water Splitting

open access: yesCarbon Energy, EarlyView.
A novel CoMoP/C3N4/NC heterogeneous interface was prepared, which exhibits outstanding HER/OER activity and durability, and requires an ultralow cell voltage of 1.496 V to achieve 10 mA cm−2 overall water splitting current. A novel multi‐site synergistic catalytic mechanism was revealed by the structural and electronic characterizations and DFT ...

Comparative Evaluation of Changes of Cardiac Output and Stroke Volume due to the Increase of Tidal Volume in Mechanical Ventilation of Pulmonary during Controlled Hypotension by Nitroglycerine and Na Nitroprusside

open access: yesMajallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2014
BACKGROUND AND OBJECTIVE: Mechanical ventilation affects heart and hemodynamic function. Nitroglycerine (NG) and Na Nitroprusside (NPS) are used to apply as deliberate hypotension by decreasing the preload and afterload of heart, respectively. This study

Micelle‐Assisted Electrodeposition of γ‐MnO2 on Lead Anodes: Structural and Electrochemical Insights

open access: yesChemNanoMat, EarlyView.
γ‐MnO2 intercalated with a surfactant exhibited a specific capacitance of 478 F/g, which is twice that of pristine MnO2. Electrolysis of MnSO4 in H2SO4 with cationic surfactants (tetradecyltrimethylammonium bromide; TTAB and cetyltrimethylammonium bromide; CTAB) led to the formation of γ‐MnO2 with surfactant intercalation in an amorphous matrix. Unlike

Wetlands as environments of early human occupation: A new classification for freshwater palaeowetlands

open access: yesThe Depositional Record, EarlyView.
A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.
