INFLUENCE OF ANODIC ALUMINA USED AS SEPARATING DIELECTRIC OF SILICON AVALANCHE LEDs ON DIODE CHARACTERISTICS

Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019
A study of the influence of the formation regimes of avalanche LEDs based on nanostructured silicon on the parameters of the formed devices, such as the light emission voltage and the stability of operation has been performed.

Liquid‐phase oxidation of furfural catalyzed by magnetically separable metal oxide nanoparticles deposited on silica gel

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Oxidation of furfural (FF), a bio‐based platform chemical, was investigated using a range of iron‐, vanadium‐ and iron–zinc‐oxalates supported on silica gel (FeVOx@silica and FeZnOx@silica, respectively) as precursor for FeV@silica and FeZn@silica oxide catalysts and H2O2 as a green oxidant.

Continuous Purification of mRNA Produced by In Vitro Transcription Using High Performance Countercurrent Membrane Purification

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Messenger ribonucleic acid (mRNA) therapeutics produced by in vitro transcription must be purified to remove residual enzymes and free nucleotides. This study examines the use of high‐performance countercurrent membrane purification (HPCMP) for the purification of mRNA therapeutics based on differences in the rate of diffusion across ...

Enhanced strategies for cuproptosis‐like death in bacterial infection treatment

BMEMat, EarlyView.
This review summarizes and examines the molecular mechanisms underlying cuproptosis‐like death. Furthermore, multi‐strategy efficacy enhancement and potential enhancement approaches are analyzed. Abstract Copper, a classical antibacterial metal, has long been of interest and widely used in medical and public health applications.

Force oscillations distort avalanche shapes

Materials Research Letters, 2019
Contradictory scaling behavior in experiments testing the principle of universality may be due to external oscillations. Thus, the effect of damped oscillatory external forces on slip avalanches in slowly deformed solids is simulated using a mean-field ...

A Systemic Model for Understanding Business Interactions With Biodiversity and Ecosystems

Business Strategy and the Environment, EarlyView.
ABSTRACT Biodiversity loss and ecosystem degradation represent critical threats to human well‐being and economic resilience, challenging businesses to understand and manage their interdependence with natural systems. This study develops a systemic framework—the BioModel—that elucidates the reciprocal relationship between businesses, biodiversity, and ...

Viscosity of concentrated mRNA solutions: Implications for downstream processing

Biotechnology Progress, EarlyView.
Abstract Messenger RNA (mRNA) therapeutics can be used to protect against infectious disease and for the treatment of cancers and genetic disorders. In order to obtain the desired therapeutic dosage, it is necessary to concentrate the mRNA to levels where the viscosity of the mRNA solutions can become significant.

Embedding a Dinuclear Ru─Pt Photocatalyst Into Polyampholytic Graft Copolymer Matrix Enables Prolonged Hydrogen Evolution While Allowing Catalyst Repair

Chemistry – A European Journal, EarlyView.
A unimolecular polyampholytic graft copolymer matrix provides a protective confinement for an electrostatically embedded tetrapyridophenazine‐bridged heterodinuclear Ru‐Pt hydrogen evolving photocatalyst. The matrix slows the degradation kinetics of the catalyst and at the same time does not hinder its repair by ammonium persulfate.

Dynamic Calibration of DEM Simulations Using Rotating Drum Experiments Using the Mean Absolute Error

Chemie Ingenieur Technik, EarlyView.
Calibrating DEM simulations is challenging due to unknown microscopic parameters. Rotating drum experiments are combined with image‐based analysis and Latin Hypercube Sampling (LHS). An area‐based Mean Absolute Error (MAE) enables reliable identification of optimal parameter sets.

Combining paleoecology and modeling to explore cascading disturbances in forest ecosystems

Ecography, EarlyView.
Climate‐induced cascading disturbance interactions pose a major challenge to the sustainable provision of forest ecosystem services to society. Developing a deeper understanding and enhanced capacity to simulate these interactions is essential for identifying disturbance‐induced tipping points in forest ecosystems, and for improving management in ...
