Smart Functional Hydrogels: Emerging Platforms for Thermal and Electrochemical Energy Harvesting and Conversion Systems

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The hydrogel exhibits versatile functions, including efficient thermogalvanic conversion under a temperature difference, and acting as a cooling layer/forming a thermally conductive nanoactive composite for thermovoltaic conversion. Additionally, its self‐healing and self‐powered flexibility play a key role in energy storage systems. The growing demand

Marangoni convection in binary mixtures with Soret effect

open access: yes, 1998
International audienceMarangoni convection in a differentially heated binary mixture is studied numerically by continuation. The fluid is subject to the Soret effect and is contained in a two-dimensional small-aspect-ratio rectangular cavity with one ...

Hydrothermal analysis of Non-Newtonian second grade fluid flow on radiative stretching cylinder with Soret and Dufour effects

open access: yesCase Studies in Thermal Engineering, 2019
The present paper examines the analytical approach of a second grade fluid flow along a stretching cylinder and the Soret and Dufour effects is also investigated on the problem. The flow is subjected to thermal radiation. A system of non-linear equations

Hydrogen Production With Water Electrolysis Technologies: Advances, Performance, and Potential Use for Low‐Gradient Combustion

open access: yesEnergy Science &Engineering, EarlyView.
This review links recent advances in water electrolysis with hydrogen utilization in low‐gradient combustion systems. While hydrogen eliminates direct CO2 emissions, its environmental and economic benefits depend strongly on production pathways, system‐level efficiency, and NOx mitigation through MILD/FLOX/HiTAC combustion.

The detrimental effect of thermal exposure and thermophoresis on MHD flow with combined mass and heat transmission employing permeability

open access: yesInternational Journal of Applied Mechanics and Engineering
We look at the viscous free-convective transitional magnetohydrodynamic thermal and mass flow over a plate that is always perforated and standing upright through permeable media while thermal radiation, a thermal source, and a chemical reaction are all ...

Study of Molecular Interactions in MCH and 1-Alkanol Mixtures Regarding the Soret Effect [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering
In this research, we have investigated the dominant intermolecular forces governing the behavior of binary systems composed of methylcyclohexane (MCH) and n-alkanols (ranging from 1-pentanol to 1-decanol) within the temperature range of 293.15 K to 323 ...

Sustainable plant‐leaf‐derived carbon dots with deep‐red emission enable 1‐min photodynamic therapy of tumors

open access: yesFlexMat, EarlyView.
In this study, plant‐derived carbon dots (CDs) were prepared using natural plant leaves as raw materials through solvothermal method. These CDs retain the porphyrin structure from chlorophyll and can simultaneously generate I and II types of reactive oxygen species. A 660 nm laser irradiation for only 1 min can achieve efficient photodynamic anti‐tumor

Wavelength dependence of the efficiency of singlet oxygen generation upon photoexcitation of photosensitizers

open access: yesEPJ Web of Conferences, 2017
The dependence of the efficiency of singlet oxygen (1Δg) generation upon excitation of photosensitizer at different wavelength was observed for several derivatives of palladium porphyrin in carbon tetrachloride.

Dufour and Soret effects in a magnetized and nonmagnetized plasma

open access: yesPhysics of Plasmas, 2007
It is well known that magnetic fields affect heat conduction in a different way in the direction parallel and perpendicular to the field. In this paper, a formal derivation of this phenomenon and analytical expressions for the transport coefficients based in the Boltzmann equation are presented. Moreover, the Dufour effect or diffusion thermo-effect is
