Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

A crystalline stannyne

Nature Chemistry
Abstract The synthesis of heteronuclear alkyne analogs incorporating heavier group 14 elements (R1−C≡E−R2, E = Si, Ge, Sn, Pb) has posed a longstanding challenge, with no previous reports on isolable compounds of this nature. Until now, neutral silynes (R1−C≡Si(L)−R2) and germynes (R1−C≡Ge(L)−R2) stabilized by a Lewis base have achieved ...

Constraints on graphite crystallinity in some Spanish fluid-deposited occurrences from different geologic settings

, 1999
Epigenetic, vein-type graphite mineralization originates by deposition from C—O—H fluids in high-temperature environments. Consequently, fluid-deposited graphite is uniformly highly crystalline in volumetrically large occurrences.

Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry

Advanced Functional Materials, EarlyView.
In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

A Crystalline In(II) Hydride [PDF]

Journal of the American Chemical Society
Low oxidation state hydride species of heavier main-group elements are notoriously elusive due to their intrinsic instability and rapid decomposition, generating hydrogen. Nevertheless, they offer significant potential for small-molecule activation and catalysis. Herein, we report the synthesis and characterization of the first stable, crystalline, low

Local Crystallinity in Twisted Cellulose Nanofibers

, 2020
Cellulose is crystallized by plants and other organisms into fibrous nanocrystals. The mechanical properties of these nanofibers and the formation of helical superstructures with energy dissipating and adaptive optical properties depend on the ordering ...
