Advanced Engineering Materials, EarlyView.This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Nanocable-Aligned ZnS Tetrapod Nanocrystals
, 2016 An effective method for synthesizing ZnS-core/carbon-sheath nanocables and nanocable-aligned ZnS tetrapod nanocrystals has been developed. Nanocable heterostructures and nanocable-linked ZnS tetrapods were synthesized in a controllable way. The tetrapods

Advanced Engineering Materials, EarlyView.Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...

The bipolar doping of ZnS via native defects and external dopants
, 2009 By employing first-principle total-energy calculations, a systematic study of the dopability of ZnS to be both n- and p-types compared with that of ZnO is carried out. We find that all the attempted acceptor dopants, group V substituting on the S lattice

, 2017 Chemical vapor deposited (CVD) ZnS is a promising long-wave infrared (8-12 mu m) window material. Yet antireflection is necessary since Fresnel reflection from its surface is high due to the high refractive index of ZnS.

Active Corrosion Protection of Sintered AA7075 Aluminum Alloy via Mn Powder Addition
Advanced Engineering Materials, EarlyView.AA7075 containing Mn‐rich particles is fabricated via spark plasma sintering using AA7075 and Mn powders. Corrosion resistance is evaluated through dip‐and‐dry tests using 0.1 M NaCl (pH 6.0), and mass loss decreases with increasing Mn addition. Mn‐rich particles function as a source of Mn ions, and formation of Mn‐accumulation films on Cu‐containing ...

Photoluminescence properties of Eu3+-doped ZnS nanocrystals prepared in a water/methanol solution
, 2002 Monodispersed ZnS and Eu3+-doped ZnS nanocrystals have been prepared through the co-precipitation reaction of inorganic precursors ZnCl2, EuCl3, and Na2S in a water/methanol binary solution. The mean particle sizes are about 3-5 nm. The structures of the

Hybrid Microgels with ZnS Inclusions
, 2005 We report on a preparation of hybrid microgels filled with ZnS inclusions. Temperature-sensitive poly(N-vinylcaprolactam-co-acetoacetoxyethyl methacrylate) (VCL/AAEM) microgels have been used as containers for deposition of ZnS by reaction of zinc ...

Advanced Functional Materials, EarlyView.DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Energy structure and fluorescence of Eu2+ in ZnS : Eu nanoparticles
, 2000 Eu2+-doped ZnS nanoparticles with an average size of around 3 nm were prepared, and an emission band around 530 nm was observed. By heating in air at 150 degrees C, this emission decreased, while the typical sharp line emission of Eu3+ increased.
