Compostable and Recyclable Baroplastic Triblock Copolymers Enable Low‐Energy Polymer Processing

open access: yesSmall, EarlyView.
Baroplastic Poly(L‐lactide)‐block‐poly(ethylene glycol)‐block‐poly(L‐lactide) triblock copolymers enable ambient‐temperature processing under moderate pressure, reducing energy demand while preserving polymer integrity. The materials show rapid industrial compostability, effective chemical and physical recyclability, and compatibility with heat ...

Spray-wall interaction and its effects on partially premixed combustion (PPC) at low engine load

open access: yes, 2019
Partially premixed combustion (PPC) often uses the early fuel-injection strategy that could result in the spray-wall interaction involved with piston top-land crevice.

噴霧燃焼の燃焼形態に与える液滴の大きさと数密度の影響に関する数値解析 [PDF]

open access: yes, 2009
The spray combustion is applied to various practical combustors such as a diesel engine, a gas turbine, etc. However, the spray combustion is the very complicated, unsteady two-phase reactive physicochemical phenomenon composed of preheating, evaporation,

Anode‐Free All‐Solid‐State Batteries: Understanding Limitations and Charting a Path to Enhanced Performance

open access: yesSmall, EarlyView.
This review examines four factors that drive interfacial instability in sulfide‐based anode‐free all‐solid‐state batteries and thoroughly reviews corresponding performance‐enhancing strategies. The strategies are organized as follows: (1) interlayer engineering, (2) pressure‐regulating buffer layers, (3) other methods, including sacrificial cathodes ...

High Speed Visualization of Flame Response in a LOX/H2 Combustion Chamber during external Excitation

open access: yes, 2006
With a model combustion chamber the interaction of an acoustic excitation with a burning LOX/H2 spray was investigated. Pressure oscillations are coupled into the combustion chamber by an additional exhaust nozzle and a siren wheel.

Synergistic Design of a SiO2–CNT–Amorphous Carbon 3D Host for Stable SEI Formation and Long‐Term Cycling Stability of Lithium Metal Anodes

open access: yesSmall, EarlyView.
SiO2@AC‐CNT microspheres, produced by spray pyrolysis and carbonization, present a 3D host where SiO2 is uniformly embedded within the CNT‐amorphous carbon framework. The architecture balances electronic conductivity and lithiophilicity, guiding uniform, dendrite‐free lithium deposition.
