Mechanistic insights into high strain rate deposition of tantalum carbide coatings via cold spray

Materials & Design
While cold spray (CS) is traditionally limited to metals and metal-ceramic composites, this study demonstrates its capability to consolidate a pure ultra-high temperature ceramic (UHTC), tantalum carbide (TaC), a superhard material considered highly ...

Band Alignment in In‐Oxo Metal Porphyrin SURMOF Heterojunctions

Advanced Functional Materials, EarlyView.
Porphyrin core metalation in indium‑oxo SURMOFs enables systematic tuning of band edge positions without altering the crystal structure. First‑principles calculations reveal type‑I and type‑II heterostructures as well as multi‑junction energy cascades, establishing a modular strategy for exciton funneling and charge separation in optoelectronic ...

Spraying Mechanism of Hot Spray Gun

Journal of the Metal Finishing Society of Japan, 1956
To study the spraying mechanisms of spray guns, a series of researches on the influence of painting conditions such as quality of paints, spray distances and air pressure on the spray pattern, distributions and amounts of spray, thickness of coating painted, and size of spray mist was carried out.The relations between paint nozzles and air caps, as ...

Supraparticles Composed of Graphitic Carbon Nitride Nanoparticles and Silica‐Supported Horseradish Peroxidase as Customizable Hybrid Catalysts for Photo‐Biocatalytic Cascade Reactions in Continuous Flow

Advanced Functional Materials, EarlyView.
Herein presented supraparticles combine the nanoparticulate photocatalyst graphitic carbon nitride with the enzyme horseradish peroxidase, which is immobilized on silica nanoparticles. In an optimized compatibility range, both catalysts operate effectively within the hybrid supraparticles and catalyze a cascade reaction consisting of the photocatalytic

Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore

Advanced Functional Materials, EarlyView.
To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...
