Carbon Energy, EarlyView.A mixed ion‐electron thermoelectric generator (MTEG) based on MXene ionogels converts both steady and fluctuating temperature gradients into continuous electricity. The hybrid conduction arises from electron tunneling through MXene networks and ionic diffusion driven by the Soret effect, enabling stable voltage output and high thermopower for efficient

Bond Strength of Acetylated Wood Glued with Thermoplastics
Mokuzai Gakkaishi, 2011 アセチル化したスギ材を，ポリ酢酸ビニル（PVAc），ポリエチレン（PE）およびポリスチレン（PS）を用いて接着し，それらの接着特性を気乾状態および湿潤状態で測定した。アセチル化によって水エマルション型PVAcの接着性能は若干低下したが，酢酸エチルに溶解させたPVAcを用いた場合には逆の傾向が認められた。アセチル化に伴う木材の疎水化で，疎水性溶剤の濡れ性が向上するものと推察された。アセチル化によってPSの接着性能は向上したが，PEの接着性能は変化しなかった。木材のアセチル化は，特にPSに対する親和性を高める効果があると推察された。PVAcやPEでアセチル化木材を接着した場合，温水浸せきによって接着強度が30－90％低下したが，PSの接着強度は湿潤によって10－20％しか低下せず，アセチル化木材 ...

Deep Underground Science and Engineering, EarlyView.Based on the 90 datasets, ERT and four optimization algorithms were used to build four hybrid models to predict the UCS of the backfill body. The SMA‐ERT model was the most effective model, and it can reliably guide the design of the backfill ratio parameters. Abstract This study analyzed the feasibility of using titanium (Ti) tailings as a backfilling

The Effect of Clamping Pressure and Orthotropic Wood Structure on Strength of Glued Bonds
, 2007 Reference values for compression strength perpendicular to the grain were determined for radial and tangential sections of samples of sugar maple and ponderosa pine. Samples to be glued were matched according to specific gravity and orthotropic structure

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.High‐performance SIB anodes are developed using mangrove wood–derived hard carbon, optimized through controlled carbonization temperatures and pitch‐derived soft carbon coatings. The resulting PC‐10 composite achieves a superior reversible capacity of 297.5 mAh g−1 and an 82% ICE by suppressing irreversible reactions and enhancing interfacial stability

Char Layer Thickness Evolution During Structural Timber Fire Experiment and Final Density Profile
Fire and Materials, EarlyView.ABSTRACT This paper evaluates several non‐destructive experimental methods for determining the char layer thickness and its density profile in structural timber samples exposed to standard ISO 834 fire curve experiments. Microwave echo pulse, ultrasonic echo pulse, X‐ray computed tomography, and resistance drilling were evaluated.

Fire and Materials, EarlyView.ABSTRACT Heat induced delamination (HID) is a phenomenon in engineered wood products which may result in the detachment of the bonded timber lamellae before charring propagates to the bond line interphase. This study aims to correlate the thermal degradation of two 1‐c‐polyurethane adhesives at the microscale to the thermo‐hydro‐mechanical behaviour of

Charring Behaviour of Mass Timber: A Comparison of Thin Intumescent Coatings and Plasterboard
Fire and Materials, EarlyView.ABSTRACT This study compares the charring behaviour of mass timber under varied heating conditions when protected by either different thin intumescent coating types or fire‐rated plasterboard layers. Bench‐scale fire experiments were conducted using the Heat‐Transfer Rate Inducing System (H‐TRIS).
