Modeling of spray characteristics from multi-hole injector for direct-injection gasoline engines

, 2006
Gasoline sprays from high-pressure multi-hole nozzles for direct injection spark-ignition engines have been simulated using a CFD spray model. Model validation takes place against experimental data available for injection into a constant volume chamber ...

Investigation of the laser fluence and wavelength dependence in surface‐assisted laser desorption/ionization mass spectrometry using gold nanoparticles

Rapid Communications in Mass Spectrometry, EarlyView.
Rationale Surface‐assisted laser desorption/ionization (SALDI) mass spectrometry (MS) builds on the use of nanostructured surfaces (e.g., coatings of colloidal nanoparticles) to promote analyte desorption and ionization. The SALDI process is believed to occur mainly through thermal processes, resulting from heating of the nanosubstrate upon absorption ...

Recyclable Printed Liquid Metal Composite for Underwater Stretchable Electronics

Small Science, Volume 5, Issue 5, May 2025.
This work presents a multifunctional liquid metal (LM) microdroplet‐based composite with a custom‐designed block copolymer as the matrix, optimized for printing. The composite exhibits high conductivity, stretchability, durability in dry and aqueous environments, and recyclability of LM using green solvents. These properties highlight its potential for

Further developments of a novel self-driven spray nozzle

, 2006
An experimental study of a further development of a novel atomizing nozzle is presented. The novelty of the nozzle lies in the incorporation of a self-driven, hydraulic turbine, which provides improved atomization performance.

Perfluorohexanone for Clean Fire Suppression: Mechanisms, System Design, Applications, and Future Directions

Safety Science and Technology, EarlyView.
Driven by halon and high GWP agent phase out, perfluorohexanone is increasingly deployed in enclosures such as data centers, marine machinery spaces, and industrial process lines. This review summarizes application performance, discharge and distribution design, material compatibility, and byproduct control and maps practical gaps for large volume and ...

Printing to Fight Antimicrobial Resistance Through Nano/Microstructured Platforms

The Chemical Record, EarlyView.
Additive manufacturing enables the rational design of structured antimicrobial platforms across multiple length scales, from nanofibrous scaffolds and droplet microreactors to 3D and 4D printed constructs. By engineering confinement, interfacial chemistry, and stimuli‐responsive release, these systems exert localized action through complementary ...

Degree of insecticide exposure and access to nectar impact survival of Trissolcus japonicus, a hymenopteran parasitoid, in flowering border strips

Agricultural and Forest Entomology, EarlyView.
We applied three thiamethoxam spray treatments to buckwheat border strips: control (no nearby spray), drift (adjacent peach trees directly sprayed) and direct spray (buckwheat and peaches directly sprayed). Drift‐treated buckwheat received about 1.4% the amount of thiamethoxam as direct‐spray buckwheat. This amount has no lethal effects on parasitoids,
