Heat transport with advection in fractured rock [PDF]

, 2019
In the transport of heat in porous media, diffusion generally dominates over advection due to slow fluid velocities imposed by low permeability. This is the reason why standard Galerkin formulation leading to extra non-symmetric matrix terms may be still

Role of Liquid Composition in the Transient Liquid Assisted Growth of Superconducting YBa2Cu3O7‐δ Films

Advanced Materials, EarlyView.
The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.

Promoting Electrochemical Reactions with Dual‐Atom Catalysts for High‐Rate Lithium–Sulfur Batteries

Advanced Materials, EarlyView.
A scalable strategy for synthesizing transition metal–bismuth atomic pairs on carbon nitride to accelerate sulfur redox reactions in lithium–sulfur batteries is presented. Nickel‐bismuth and cobatl‐bismuth catalysts improve rate performance by promoting direct electrochemical transitions and rapid Li2S nucleation, minimizing sulfur loss, and enhancing ...

Customizable 3D‐Printed SiC Photocatalysts for Microplastic Capture and Degradation under Flow and Static Conditions

Advanced Sustainable Systems, EarlyView.
Microplastics (MPs) are persistent environmental pollutants that adsorb hazardous compounds and bioaccumulate, posing risks to ecosystems and human health. Photocatalytic degradation offers a sustainable solution, but conventional powder‐based photocatalysts hinder scalability.

Co‐Sensitized Solar Cell Achieves 13.7% Efficiency with Bis‐Hexylthiophene Dyes

Advanced Science, EarlyView.
The authors demonstrate that the longer excited state lifetime dye in combination with a copper electrolyte produces a high photovoltage of 1.22 V, owing to retarded interfacial charge recombination. The co‐sensitized solar cell achieves efficiencies of 13.7% under full sunlight and 29.7% under LED light.

Highly Efficient Air Sterilization via Low‐Temperature Interfacial Evaporation in Inductively Heated Superhydrophilic Ferromagnetic Filters

Advanced Science, EarlyView.
The first low‐temperature interfacial evaporation air sterilization technology is presented. It is based on a superhydrophilic ferromagnetic micro/nano‐structured stainless‐steel filter, showing ultra‐efficient inductive heating. This technology has demonstrated over 99.6% of SARS‐CoV‐2 and RSV elimination at temperatures in the 60–80 °C range.
