Nanostructured Optical Superabsorbers from Carbon Nanotube Forest for Heat Management Using Environmental Blackbody Radiation from the Visible to Mid‐Infrared

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Our computational model of the optical absorption from multiwalled carbon nanotubes suggests the optical absorption depends strongly on the in‐plane electrical conductivity, and weakly on the through‐plane conductivity. Such strong absorption enables solar‐to‐thermal conversion for heat scavenging in cold climates and radiative cooling in hot climates,

Enhanced Structural Reversibility and Electrochemical Stability Via Fe3+/Fe4+ Stabilization in a P3‐Type Layered Na0.7[Mn0.5Fe0.4Li0.1]O2 Cathode at High‐Voltages

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Partial Li substitution for Fe in a P3‐Type layered Na0.7[Mn0.5Fe0.4Li0.1]O2 cathode stabilizes the iron redox behavior, particularly at higher charging voltage up to 4.5 V (vs Na/Na+), that enables more reversible sodium‐ion storage capacity and significantly improves capacity retention.

Qualitative Analysis of Biogas by Raman Spectroscopy: Effect of Pressure on Major Components

open access: yesJournal of Raman Spectroscopy, EarlyView.
Raman spectra of major and selected minor biogas components were studied under pressures up to 100 bar. Pressure‐induced shifts and band broadening were quantified for methane, carbon dioxide, and nitrogen, while Raman spectra of ammonia and hydrogen sulfide are presented in the context of biogas quality monitoring.

Soluble oat components: effects of kilning on extraction and functionality

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND This study evaluated the effect of kilning on physicochemical and functional properties of soluble fraction in oat varieties. Kilning was applied prior to extraction, and its impact on composition, extractability and functionality was evaluated.

Kinetic Study on the Reaction of Phenylperoxy Radicals With Nitric Oxide

open access: yesInternational Journal of Chemical Kinetics, EarlyView.
ABSTRACT Cavity ring‐down spectroscopy (CRDS) and quantum cascade laser absorption spectroscopy (QCLAS), in conjunction with pulsed laser photolysis, were employed to investigate the reaction between phenylperoxy radicals (C6H5O2) and nitric oxide (NO) at a temperature of 296 ± 4 K. The experiment was carried out under N2 as bath gas.

Chain‐End Grafting of RAFT Polyelectrolyte Macroligands to Stabilize Near‐Infrared‐Emitting Gold Nanoclusters

open access: yesMacromolecular Rapid Communications, EarlyView.
Surface‐functionalized gold nanoclusters (AuNCs) are synthesized in situ by chain‐end grafting of RAFT polyelectrolytes at room temperature directly in water. It leads to highly stable polymer‐AuNCs nanohybrids emitting near‐infrared photoluminescence with µs lifetimes. ABSTRACT With their photoluminescence properties, gold nanoclusters (AuNCs, d<2 nm)
