Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review

Heat Transfer, EarlyView.
ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

Surface‐State–Regulated Product Distribution in Photothermal CO2 Hydrogenation Over MXene‐Based S‐Scheme Catalyst

Angewandte Chemie, Volume 138, Issue 12, 16 March 2026.
This work establishes an MXene‐based S‐scheme heterojunction in which the cooperative interplay among metallic Ni, surface NiOx domains, and conductive Ti3C2Clx drives efficient charge separation and photothermal coupling. Progressive evolution of Ni surface states regulates the CH4/CH3OH product distribution by modulating interfacial energetics and ...

Effects of Transition Metals (TM = Nb, Ta, and Zr) on Thermodynamic and Electronic Properties of Advanced (Th1−xTMx)C (x = 0.1 and 0.2) Fuels: A First‐Principles Study

Materials Genome Engineering Advances, EarlyView.
First‐principles study reveals Zr‐doped ThC maintains superior thermal conductivity and rigidity; Ta‐doping induces structural softening, whereas Nb enhances covalent bonding. These atomic‐scale insights guide the design of advanced thorium‐based nuclear fuels with tailored thermomechanical properties.
