Microstructure, Thermal Transport, and Dry‐Sliding Tribology of Powder‐Metallurgy Al7075 Composites Reinforced With Sol–Gel‐Derived ZnO–rGO Hybrid Nanoparticles

open access: yesAdvanced Engineering Materials, EarlyView.
Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...

[μ2-Bis(diphenylphosphanyl)hexane]bis[undecacarbonyl-triangulo-triruthenium(3 Ru—Ru)] hexane monosolvate: crystal structure and Hirshfeld surface analysis

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2017
In the title cluster complex hexane solvate, [Ru6(C30H32P2)(CO)22]·C6H14, two Ru3(CO)11 fragments are linked by a Ph2P(CH2)6PPh2 bridge with the P atoms equatorially disposed with respect to the Ru3 triangle in each case; the hexane solvent molecule is ...

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

μ-Carbonyl-bis(carbonyl{η5-[tricarbonyl(η6-2-methylindenyl)chromium(0)]rhodium(III)})(Rh—Rh)

open access: yesIUCrData, 2019
The structure of the title complex, [Cr2Rh2(C10H9)2(CO)9], was solved by single-crystal X-ray diffraction analysis in the P21/c space group. The crystal shows two units of the tetrametallic complex in the asymmetric unit.

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics

open access: yesAdvanced Functional Materials, EarlyView.
We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...

Vibration-rotation bands of carbonyl sulfide

open access: yes, 1962
Thirty-two infrared absorption bands of carbonyl sulfide (OCS) have been measured and are reported here, seventeen for the first time. Seven absorption bands due to isotopic molecules were also measured. Rotational constants have bee n determined and the

High throughput identification of carbonyl compounds in natural organic matter by directional derivatization combined with ultra-high resolution mass spectrometry

open access: yes, 2023
Carbonyl compounds are an important component of natural organic matter (NOM), widely distributed in atmosphere, water, soil and organisms. However, our understanding on the molecular composition of these carbonyl compounds is still limited due to the ...

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

open access: yesAdvanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...
