The mechanism of spontaneous corrugation on the snowy and icy roads produced by the moving vehicles in cold regions

open access: yesJournal of Infrastructure Preservation and Resilience
Traffic safety in cold regions is seriously affected by the snow and ice brought by the extreme climate. The snowy and icy road cannot provide enough friction for the safe operation of vehicles due to its smooth and uneven surface.

Effect of different flue gas recirculation rates on low‐NOx combustion characteristics: A numerical simulation based on the combustion process of a gas boiler

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract NOx emissions from gas boilers severely impact the environment, and flue gas recirculation (FGR) technology can effectively reduce such emissions, yet the effects of different FGR rates on combustion performance and NOx formation remain unclear. This study thus used numerical simulation (via ANSYS Fluent, adopting the realizable k‐ε turbulence

Shock wave propagation characteristics of aluminum‐containing explosive in corrugated steel‐lined tunnel

open access: yesDeep Underground Science and Engineering, EarlyView.
Aluminum‐enhanced afterburning renders AE explosives more hazardous than conventional ones. Corrugated steel linings reduce far‐field AE blast overpressure by ~50% through wave reflection and dissipation. The developed model accurately predicts peak pressure (<10% error) and arrival time (<3% error), supporting protective design.

A comprehensive embryonic staging series of the turtle Trachemys scripta

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Turtles hold a unique place in vertebrate evolutionary history, making them critical assets in embryology research. Yet, they remain understudied as potential model organisms in the field. Here, to support experimental manipulations with turtle embryos, we have created a complete normal table of development for comprehensive ...

Biophysical processes of morphogenesis in lizard lungs

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The lungs of squamate reptiles (lizards and snakes) are highly diverse, exhibiting single chambers, multiple chambers, transitional forms with two to three chambers, along with a suite of other anatomical features, including finger‐like epithelial projections into the body cavity known as diverticulae.

Dynamic Chloride‐Ion Adsorption on Ag Nanoparticles and Carboxylic Acid Ligands: Enabling Highly Stable Industrial‐Scale Seawater Oxidation

open access: yesEcoEnergy, EarlyView.
We propose a strategy where trimesic acid (TA) is anchored between LDH layers, enabling Ag nanoparticles to preferentially adsorb free Cl− to form AgCl. By modulating the charge environment within LDH layers, both chlorine corrosion resistance and OER activity are enhanced, enabling long‐term stable operation under industrial conditions.

Optimal Nanoparticle Size in SiO₂/Al₂O₃‐Water Nanofluids for Enhancing Intercooler Thermal Enhancement: A Conjugate Heat Transfer Study

open access: yesEnergy Science &Engineering, EarlyView.
The simulation shows that the comprehensive heat transfer effect of using nanofluids as cooling liquid is greater than 1.30 nm SiO2/water and 40 nmAl2O3/water nanofluids have the best heat transfer enhancement effect, while all nanofluids of 30 nm Al2O3/water have the best heat transfer enhancement effect.

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

open access: yesHeat 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

Tailoring SHG Efficiency via t‐Te Nanocrystals in Tellurite Glasses by Femtosecond Laser Micromachining

open access: yesLaser &Photonics Reviews, EarlyView.
Femtosecond laser irradiation at the glass surface induces symmetry breaking and crystallization of triclínic t‐Te nanophases, enabling intense second‐harmonic generation (SHG). The illustration depicts the fs‐pulse interaction, structural rearrangement, and nonlinear activation from amorphous tellurite glass to crystalline regions.
