What is a good conductor for metamaterials or plasmonics

Nanophotonics, 2015
We review conducting materials like metals, conducting oxides and graphene for nanophotonic applications. We emphasize that metamaterials and plasmonic systems benefit from different conducting materials.

Characterization of Oxide-Dispersion-Strengthened (ODS) Alloy Powders Processed by Mechano-Chemical-Bonding (MCB) and Balling Milling (BM)

KONA Powder and Particle Journal, 2014
Two types of powder processing techniques, Mechano-Chemical-Bonding (MCB) and MCB plus ball-milling (BM) with reduced time, have been employed to process the nickel-based oxide-dispersion-strengthened (ODS) alloy ...

Design of Experiments as a Tool to Optimize the Process of Coating Minitablets with Commercial Gastro-Resistant Coating Mixtures

Pharmaceutics, 2022
According to the Quality by Design (QbD) concept, Design of Experiment (DoE) was used to indicate critical process parameters and optimize the fluid bed coating of minitablets in a laboratory size batch.

Bacterial endosymbionts influence host sexuality and reveal reproductive genes of early divergent fungi

Nature Communications, 2017
Cells of the fungus Rhizopus microsporus contain Burkholderia endobacteria that control its asexual reproduction. Here, the authors show that the endobacteria also mediate mating of the fungal host by modulating expression of a GTPase central to fungal ...

Sorting rare earth magnets motors for recycling without opening the motors

Scientific Reports
A novel approach for sorting electric motors without dismantling them is reported in this article. This approach increases the likelihood that a motor selected from a mixture for recycling would contain rare earth elements (REEs), which are pivotal for ...

Identifying the Characteristics of Promising Renewable Replacement Chemicals

iScience, 2019
Summary: Although several “renewable” strategies have been recently proposed to produce high-volume as well as new (replacement) chemicals, the identification of good targets for such strategies remains challenging.

Thermoreflectance Detection of Point Defects Resulting from Focused Ion Beam Milling

Advanced Engineering Materials, EarlyView.
Focused ion beam (FIB) milling is a common tool for nanoscale material processing, however irradiation damage, redeposition, and contamination can occur. We use several characterization tools to show FIB‐induced effects beyond 1 mm from the milled area.

Enhanced Phase Stability of Sm₂(Fe, Al)₁₇C_x

Inorganics
Aluminum doping can improve the phase stability of metastable compound Sm2Fe17Cx with a high carbon content (x > 1.5). We investigated the preferential site substitution of Al, chemical bonding, and structural stability in Sm2(Fe,Al)17C3 using first ...
