Novel multi–SO3H functionalized ionic liquids as highly efficient catalyst for synthesis of biodiesel

Green Energy & Environment, 2021
Biodiesel is an attractive alternative to fossil fuels due to the energy and environmental concerns. In this paper, seven different multi –SO3H functionalized ILs based on the low-cost less-substituted amines, which contained massive sites for ...

Comparative study on the effect of different copper loading on catalytic behaviors and activity of Cu/ZnO/Al2O3 catalysts toward CO and CO2 hydrogenation

Heliyon, 2021
The ternary Cu/ZnO/Al2O3 (CZA) catalysts having different Cu loading were prepared by the co-precipitation method. Then, they were used in CO and CO2 hydrogenation to produce methanol under atmospheric pressure at 250 °C. The high Cu loading CZA catalyst

A Photovoltaic Device Using an Electrolyte Containing Photosynthetic Reaction Centers

Energies, 2010
The performance of bio-photovoltaic devices with a monolayer of the immobilized photosynthetic reaction center (RC) is generally low because of weak light absorption and poor charge transfer between the RC and the electrode.

Role of tyrosine M210 in the initial charge separation of reaction centers of Rhodobacter sphaeroides [PDF]

, 1990
Femtosecond spectroscopy was used in combination with site-directed mutagenesis to study the influence of tyrosine M210 (YM210) on the primary electron transfer in the reaction center of Rhodobacter sphaeroides.

Beyond Native Reaction Centers [PDF]

, 1990
The past five years after solving the crystal structure of the bacterial reaction center from Rhodopseudomonas (Rp.) viridis [1] — and the first Feldafing meeting [2] — have witnessed a remarkable concentration of interdisciplinary research on this pigment-protein complex.

Cardiolipin increases in chromatophores isolated from Rhodobacter sphaeroides after osmotic stress: structural and functional roles

Journal of Lipid Research, 2009
Chromatophores isolated from cells of Rhodobacter sphaeroides exposed to hypertonic solutions were enriched in cardiolipin (CL). Because CL levels are raised by increasing the incubation time of R.

Elucidation of Pd modification effect on catalytic behaviors of γ-Al2O3-P catalysts toward ethanol dehydration and dehydrogenation

Catalysis Communications, 2021
The catalytic ethanol dehydration and dehydrogenation over γ-Al2O3-P catalysts with Pd modification were investigated. The Al2O3-P is promising to obtain the highest yield of diethyl ether (ca.

Ultrafast structural dynamics of carbon–carbon single-bond rotation in transient radical species at non-equilibrium

Nature Communications
Bond rotation is an important phenomenon governing the fate of reactions. In particular, heterogeneously substituted ethane derivatives provide distinct structural conformations around the bond, empowering them as ideal systems for studying the rotation ...
