Development of high-emittance scales on thoriated nickel-chromium-aluminum-base alloys [PDF]

The surface regions of a DSNiCrAl alloy have been doped, by a pack diffusion process, with small amounts of Mn, Fe, or Co, and the effect of these dopants on the total normal emissivity of the scales produced by subsequent high temperature oxidation has ...

DNA Flap‐Mediated Control of Transcription for Programmable RNA Synthesis

Angewandte Chemie International Edition, EarlyView.
Pyrimidine‐rich ssDNA flaps on the T7 promoter inhibit T7 RNA polymerase (T7RP) transcription. Leveraging this pyrimidine bias, we developed DNAzyme‐ and MNAzyme‐mediated flap promoter induced transcription control (D‐FIT and M‐FIT) systems. These platforms enable regulated transcription and sequence‐specific detection, highlighting the programmable ...

An All‐in‐One Lignin‐Based Artificial Thylakoid Nanovesicle Via In‐Situ Confined Growth Strategy for High‐Efficient and Selectivity CO2 Photoreduction

Carbon Energy, EarlyView.
The low light/CO2 capture and slow dynamic transfer of photogenerated electrons hamper photocatalysts’ high activity and selectivity. Inspired by the chloroplast's photosynthesis mechanism, an all‐in‐one lignin‐based artificial thylakoid nanovesicle (AiO‐L‐ATN) is constructed using a confined growth strategy of lignin molecules. The performance of such

The thermal stability and degradation mechanism of Cu/Mo nanomultilayers

Science and Technology of Advanced Materials
The microstructural evolution of Cu/Mo nanomultilayers upon annealing was investigated by X-ray diffraction and transmission electron microscopy. The isothermal annealing process in the temperature ranges of 300–850°C was conducted to understand the ...

Regulating Interfacial Hydrogen‐Bonding Connectivity by Oxygen Vacancies‐Driven [Fe(CN)6]3− Coordination for Boosting Hydrogen Peroxide Electrosynthesis

Carbon Energy, EarlyView.
ABSTRACT The inherent hydroxide‐rich (OH⁻) environment in alkaline media facilitates the two‐electron oxygen reduction reaction (2e−ORR). However, the strong interaction between alkali metal cations and solvated water molecules significantly reduces the connectivity of the hydrogen bond network within the alkaline electric double layer, thereby ...

Recent Progress on Fullerene–Based Functional Materials for Energy Conversion

Carbon Energy, EarlyView.
A schematic illustration summarizing the classification, and photo‐/electro‐‐/thermo‐catalysis and energy storage applications of C60 and derivatives. ABSTRACT Efficient energy conversion and environmental protection are still constrained by rapid carrier recombination, unstable interfaces, limited active site, and so on. Owing to the unique electronic

Preparing an Exsolvable Ru‐Substituted LaFeO3 Perovskite With High Surface Area From a Self‐Sacrificial Polymer Template: A Versatile Strategy for Enhanced Catalytic Performance

Chemistry – A European Journal, EarlyView.
High‐surface‐area LaFe0.9Ru0.1O3 is prepared by infiltration of porous Amberlite XAD16 polymer beads. Ru exsolution of this perovskite material leads to a supported catalyst with small Ru particles, exhibiting promising catalytic performance propane combustion.

Modelling of continuous low‐temperature emulsion co‐polymerization in 3D‐printed reactor

The Canadian Journal of Chemical Engineering, EarlyView.
A kinetic model for the emulsion copolymerization of butyl acrylate/styrene at low temperatures is proposed and validated against experiments with a redox initiator system. The model was successfully transferred to a 3D‐printed tubular reactor and conversions of more than 80% and small particles sizes below 40 nm were observed.

Optimal model‐based design of experiments for parameter precision: Supercritical extraction case

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...
