Eco‐Friendly Synthesis of Cobalt Phthalocyanine for High‐Efficiency CO2${\rm CO}_{2}$ Electroreduction

Chemistry – A European Journal, EarlyView.
A sustainable synthesis of cobalt phthalocyanine (CoPc) using low‐impact solvents yields high‐performance electrocatalysts with reduced waste (E‐factor 18.6). When integrated into gas diffusion electrodes, CoPc achieves up to 12% Faradays efficiency for CO2‐to‐methanol and 65% CO2‐to‐CO conversion, aligning with state‐of‐the‐art materials and enabling ...

Active Motion of Janus Particle by Self-thermophoresis in Defocused Laser Beam

, 2010
We study self-propulsion of a half-metal coated colloidal particle under laser irradiation. The motion is caused by self-thermophoresis: i.e. absorption of laser at the metal-coated side of the particle creates local temperature gradient which in turn ...

Linear Stability Analysis of Double Diffusive Convection in a Horizontal Sparsely Packed Rotating Anisotropic Porous Layer in Presence of Soret Effect

Journal of Applied Fluid Mechanics, 2014
In this paper, we have investigated theoretically the effect of Soret parameter on the onset of double diffusive rotating anisotropic convection in a horizontal sparsely packed porous layer using linear stability theory which is based on the usual ...

Mimicking The Photosynthetic Special Pair With Aluminum(III) Porphyrin Homodimer – Fullerene (C60) Supramolecular Assemblies Capable of Long‐Lived Charge Separation

Chemistry – A European Journal, EarlyView.
The axial‐bonding of aluminum(III) porphyrins was used to create two covalently linked special‐pair mimics to probe charge‐transfer between a porphyrin dimer and a C60 unit for artificial photosynthesis. Although excitonic coupling between the porphyrins is weak, incorporation of a second porphyrin markedly increases both the yield and lifetime of the ...

Chemical reaction in peristaltic motion of MHD couple stress fluid in channel with Soret and Dufour effects

Results in Physics, 2018
This paper looks at the peristaltic motion of MHD couple stress fluid in an inclined asymmetric channel. Simultaneous effects of heat and mass transfer are considered. Soret and Dufour features lead to the coupled differential systems.

Self‐Maintained Thermal Charging Cells for the Efficient Harvesting of Waste Heat at Elevated Temperatures

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Thermal charging cells (TCS) face two main challenges that limit their practical applications: 1) Still lacking the systems suitable for operation under higher temperature environments, and 2) there are limitations in the self‐sustaining performance of continuous discharge under temperature differences, which holds critical significance for the real ...

Influence of the Dufour effect on convection in binary gas mixtures

, 1995
Linear and nonlinear properties of convection in binary fluid layers heated from below are investigated, in particular for gas parameters. A Galerkin approximation for realistic boundary conditions that describes stationary and oscillatory convection in ...

Introducing needs‐based epilepsy follow‐up: Patient satisfaction compared to standard of care follow‐up

Epileptic Disorders, EarlyView.
Abstract Background People with epilepsy have diverse healthcare needs, but limited resources make tailored management challenging. To allocate resources where they are most urgently required, we developed an openly available needs‐based follow‐up model.
