Magnetic Control of Chiral Hybridized Phonon Magnetic Moments in Ferrimagnets Fe2‐xZnxMo3O8

open access: yesAdvanced Functional Materials, EarlyView.
Helicity‐resolved magneto‐Raman spectroscopy reveals magnetic control of chiral phonon magnetic moments in polar ferrimagnet (ZnxFe2−xMo3O₈). Large spontaneous zero‐field phonon splittings, selective phonon–magnon coupling, and asymmetric Zeeman responses demonstrate that phonon chirality is governed by magnon‐phonon coupling and magnetization.

MOFs and COFs in Electronics: Bridging the Gap between Intrinsic Properties and Measured Performance

open access: yesAdvanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) hold promise for advanced electronics. However, discrepancies in reported electrical conductivities highlight the importance of measurement methodologies. This review explores intrinsic charge transport mechanisms and extrinsic factors influencing performance, and critically ...

Hot‐Film and Calorimetric Methods With Transient Heating for Measurement of High Biofluid Flow Rate

open access: yesAdvanced Functional Materials, EarlyView.
Accurate measurement of biofluid flow rate is vital for clinical diagnostics. We propose a transient heating strategy using short thermal pulses and peak temperature tracking to enhance the flow sensitivity of the hot‐Film and calorimetric methods. Simulations show how optimal heating time maximizes sensitivity across flow rates.

Emergent Spin‐Glass Behavior in an Iron(II)‐Based Metal–Organic Framework Glass

open access: yesAdvanced Functional Materials, EarlyView.
A one‐pot, solvent‐free synthesis yields an Fe2+‐based metal‐organic framework (MOF) glass featuring a continuous random network structure. The material exhibits spin‐glass freezing at 14 K, driven by topological‐disorder and short‐range magnetic frustration, showcasing the potential of MOF glasses as a plattform for cooperative magnetic phenomena in ...

Controlled Atmosphere Exposure Chamber

Archives of Environmental Health: An International Journal, 1969
A room-sized chamber was constructed capable of automatically maintaining levels of single or mixed contaminants for prolonged periods. The system can add specific contaminants to the natural smog or filter them out or do both. The chamber can house 20 dogs or subhuman primates adequately. Air flow is laminar from side to side.

Controlled Atmosphere Chambers

2014
Abstract Controlled atmosphere chambers are used to control the surface chemistry of the metals that are being processed. This article focuses on the various types of controlled atmospheres used in induction heat treating and brazing, namely, inert gas atmospheres based on argon and helium; prepared and commercial nitrogen-base ...

Controlled atmosphere storage

1997
Controlled atmosphere (CA) storage is used to extend the storage life of seasonal perishable produce when refrigeration alone is not sufficient. This technique can be used for many fruits and vegetables and, historically, has been the principle storage method for the world’s apple crop.
