An Experimental and Numerical Study on Supported Ultra-Lean Methane Combustion

Energies, 2019
With a much larger global warming potential (GWP) and much shorter lifespan, the reduction of methane emissions offers an additional opportunity and a relatively quick way of mitigating climate change in the near future.

Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix

Advanced Functional Materials, EarlyView.
Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...

Flame Front Propagation in an Optical GDI Engine under Stoichiometric and Lean Burn Conditions

Energies, 2017
Lean fueling of spark ignited (SI) engines is a valid method for increasing efficiency and reducing nitric oxide (NOx) emissions. Gasoline direct injection (GDI) allows better fuel economy with respect to the port-fuel injection configuration, through ...

Backbone Heterojunction Photocatalysts for Efficient Sacrificial Hydrogen Production

Advanced Functional Materials, EarlyView.
Herein, a ‘single‐component’ organic semiconductor photocatalyst is presented in which a molecular donor is bonded to a polymer acceptor. The resultant material demonstrates exceptional photocatalytic activity for hydrogen evolution in aqueous triethylamine with an outstanding external quantum efficiency of 38% at 420 nm.

Study on combustion and emissions of methanol engines based on active pre-chamber jet ignition technology

Case Studies in Thermal Engineering
Against the backdrop of the ''dual carbon'' goals, this study addressed the challenges of narrow lean-burn limits and low thermal efficiency in conventional spark-ignition (SI) methanol engines by proposing the active pre-chamber jet ignition (APCH-JI ...
