Evaluation of Selected Chemical Processes for Production of Low-cost Silicon, Phase 3 [PDF]

open access: yes
The construction of the 50 MT Si/year experimental process system development unit was deferred until FY 1980, and the fluidized bed, zinc vaporizer, by-product condenser, and electrolytic cell were combined with auxiliary units, capable of supporting 8 ...

A simple, rapid method for measurement of acetate in tissue and serum.

open access: yesJournal of Lipid Research, 1975
A simple and rapid method is described for determining the free acetate concentration in liver and serum. After extraction, the acetate is converted to its benzyl ester by thermal degradation of its benzyldimethylphenylammonium salt in the vaporizer of a

Analysis of Thermal Conductivity of Frost on Cryogenic Finned-tube Vaporizer Using Fractal Method

open access: yes, 2013
Thermal conductivity of frost is not only related to density, but also affected by its microstructure and environmental conditions, and it will continuously change with the formation and growth of frost.

Ultralow‐Frequency Epsilon‐Near‐Zero States in 3D‐Printed High‐Entropy Alloy Metacomposites for Ultra‐Thin Perfect RF Absorption

open access: yesAdvanced Materials, EarlyView.
Rozanov causality limit—a compulsive proportional thickness‐wavelength relationship (nd ∝ λ)—makes it challenging to develop perfect absorption with both thin thickness and low frequency. Herein, a cocktail effect in high‐entropy alloys (HEA) is crucially utilized for lowering plasma frequency to achieve epsilon‐near‐zero states, which finally enables ...

Cycle life testing of 8-cm mercury ion thruster cathodes [PDF]

open access: yes
Two main cathodes have successfully completed 2800 and 1980 cycles and three neutralizers, 3928, 3050, and 2850 cycles in ongoing cycle life tests of flight-type cathode-isolator-vaporizer and neutralizer-isolator-vaporizer assemblies for the 4.45 mN 8 ...

Self‐Assembled Cobalt Oxide Nanobeads on the Conducting Van der Waals Semi‐Metal PtTe2 for Catalytic Heterostructure

open access: yesAdvanced Materials Interfaces, EarlyView.
Self‐assembled CoO nanobeads on the Van der Waals surface of PtTe2 were synthesized through simple thermal annealing utilizing the residual oxygen in the annealing chamber. In this study, the electrocatalytic effect for oxygen evolution reaction from CoO nanobeads on conducting PtTe2 was confirmed, elucidating the new pathway to design a ...

Evaluation of selected chemical processes for production of low-cost silicon, phase 2 [PDF]

open access: yes
Potential designs for an integrated fluidized-bed reactor/zinc vaporizer/SiCl4 preheater unit are being considered and heat-transfer calculations have been initiated on versions of the zinc vaporizer section. Estimates of the cost of the silicon prepared

Laser‐Synthesized Amorphous PdSe2‐x Nanoparticles: A Defect‐Rich Platform for High‐Efficiency SERS, Photocatalysis, and Photothermal Conversion

open access: yesAdvanced Materials Interfaces, EarlyView.
Using femtosecond ablation, we show that an ordered, stoichiometric crystalline PdSe2 target can be controllably converted into a stable, disordered, non‐stoichiometric, and highly functional amorphous nanomaterial, PdSe2−x${\rm PdSe}_{2-x}$. The obtained nanoparticles offer significant advantages over conventional planar plasmon‐free substrates due to

Are high fresh gas flow rates necessary during the wash‐in period in low‐flow anesthesia?

open access: yesKaohsiung Journal of Medical Sciences, 2020
In low‐flow anesthesia (LFA), there is a wash‐in period in which usually high fresh gas flow (FGF) rates are used to achieve the required initial concentration of anesthetic agent in the alveoli.

Atomic Layer Deposition of Highly Conducting NiS2 Thin Films from Elemental Sulfur

open access: yesAdvanced Materials Interfaces, EarlyView.
A simple new atomic layer deposition (ALD) process yields in‐situ crystalline and electrically conducting nickel disulfide thin films. This deposition process is based on two solid and safe precursors, nickel acetylacetonate and elemental sulfur. ABSTRACT A novel atomic layer deposition (ALD) process for highly conducting nickel disulfide thin films is
