Acceleration of Abrasive Particles in Premixed Abrasive Water Jet Nozzle.

JSME International Journal Series B, 1996
It has been shown that the premixed abrasive water jet system has a greater capacity for drilling and cutting than the conventional abrasive water jet system. In the present investigation, the motion of spherical particles in a premixed abrasive water jet nozzle is investigated theoretically.

Heat Transfer Performance of Biphilic Surfaces With Diatomite‐Based Composite Coatings in a Closed Thermosyphon System

Heat Transfer, EarlyView.
ABSTRACT This study investigates the thermal performance of innovative biphilic boiling surfaces designed for CPU cooling applications using a two‐phase closed thermosyphon (TPCT) system. The surfaces were fabricated by applying composite coatings—comprising epoxy resin and diatomite particles functionalized with APTES and PFOTS silanes— onto Al1050 ...

Highly Durable and Uniform Structural Coloration via Spray‐Coated Organic Mie Resonators Randomly Distributed in Three Dimensions

Laser &Photonics Reviews, EarlyView.
This study demonstrates uniform, durable non‐iridescent structural coloration using polystyrene nanoparticles randomly embedded in a thick sodium silicate with absorptive additives. By suppressing the effects of the structure factor and multiple scattering, this approach achieves uniform coloration from the backscattering.

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).
