Creep Properties and Deformation Mechanism of Additively Manufactured NiAl‐CrMo Composites

Advanced Engineering Materials, EarlyView.
Additively manufactured NiAl‐CrMo composites contain numerous interfaces and cell boundaries that control their creep response. At 700°C under high applied stress, creep is dominated by dislocation‐controlled power‐law mechanisms. At 800°C–900°C and lower stresses, creep is primarily diffusion‐controlled along cell boundaries.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

ABSORPTION SPECTRA OF DIHYDROFLAVONOLS

, 1956
Absorption spectra of 4'-OCH3- 6-Me-4'-OCH3. and 7-Me 3'-OCH3- 4'-OCH2\(\phi\)- dihydroflavonols are reported mid discussed. The spectra are very similar to that of flavanone. 4'-OCH3 or 4'-OCH2\(\phi\)- substitution does not alter the nature of the spectrum, because these are not in conjugation with C=0 and no additional resonance is possible ...

Absorption spectra of Se-8-ring clusters in zeolite 5A

, 1997
Samples with different weight ratio of Se to zeolite 5A (Se concentration) have been prepared by loading Se into the pores of zeolite 5A, and the measuerments of the absorption and Raman spectra have been carried out for the prepared samples.

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

Advanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Identification of the Interchromophore Interaction on Electronic Absorption and Circular Dichroism Spectra of Bis-Phenanthrenes

We characterize the low-lying excited electronic states of a series of bis-phenanthrenes by our newly developed diabatic scheme called the fragment particle-hole densities (FPHD) method and calculate both the electronic absorption and circular dichroism

Cathodic Cage Plasma Deposition of Nanostructured Cu–Fe–Se Coatings on Poly(methyl Methacrylate)

Advanced Engineering Materials, EarlyView.
Nanostructured Cu–Fe–Se coatings are deposited on PMMA by a modified cathodic cage plasma process, enabling low‐temperature deposition on polymer substrates. A transition from discontinuous to compact morphology is observed with temperature, with optimal properties at 200°C, where improved CuFeSe2‐type bonding, lowest sheet resistance, and favorable ...
