Application of Renewable Energies: Effects of Oxyhydrogen Negative Pressure Indraft on Combustion and Emission of Biobutanol/Gasoline Combined Supply Engine Under Exhaust Gas Recirculation Coupled Lean–Burn

Energies
Combining biobutanol and oxyhydrogen in an SI engine can reduce fossil-fuel use and improve power, but oxyhydrogen increases NOx. Without sacrificing combustion stability, this work investigates lean–burn coupled with exhaust gas recirculation for a ...

General comparison of pre-chamber jet ignition and spark ignition on combustion and emission characteristics of a methanol direct injection engine

Case Studies in Thermal Engineering
Compared with spark ignition (SI), pre-chamber jet ignition (PCJI) can effectively accelerate the combustion and extend lean burn limit. In this paper, the effects of PCJI and SI on methanol direct injection engine were investigated experimentally ...

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...
