We discuss a recent test of the performance of the kinetic energy partition method (KEP) through its application to two separable quantum-mechanical models. We argue that one of the benchmark models is exceedingly simple...

The aim of this work is to create the scientific foundations of microwave extractors implementing the effect of mechanodiffusion discovered by the authors, as well as visual, kinetic, and energy substantiation of the fun...

The kinetics of ZnFe2O4 formation starting from mechanochemically activated Zn-Fe2O3 powders are studied. Mixtures of metallic Zn and hematite were activated under air atmosphere in a high energy mill and thermally treat...

Biosorbents present a cost-effective alternative to expensive fossil-based ion-exchange resins for addressing the challenge of heavy metal contamination in wastewater treatment. Among these contaminants, cadmium poses a ...

Abstract A statistical survey using 3 years of Van Allen Probes data from 2013 to 2015 is conducted to investigate the impact of broadband kinetic Alfvén waves (KAWs) on the pitch angle distributions (PADs) of relativi...

The oxidation of diesel soot using K/CeO2 catalysts is studied in this paper. The reaction system involved in the catalytic oxidation of soot is quite complex; therefore, the study of reaction mechanisms is particularly ...

This article takes an educational perspective on a central limitation in biomass electrochemistry: the impossibility of driving multielectron reactions at the global thermodynamic potential. Standard electrode potentials...

To analyze the effects of temperature, concentration, and reaction time on the denitration rate of double based spherical gun propellant (DBSGP) and to investigate the denitration reaction-diffusion coupling process for ...

The relative importance of different processes and transitions in the appearance of non-LTE populations for the fundamental levels of ozone was studied by quantifying the kinetic law of every process and transition that ...

Cherenkov radiation (CR) is the electromagnetic shockwaves generated by the uniform motion of charged particles at a velocity exceeding the phase velocity of light in a given medium. In the Reststrahlen bands of hexagona...

The authors reported experimental results on the spatial evolution of turbulent kinetic energy and turbulence production in free weak hydraulic jumps. They performed turbulence measurements using two different 16 MHz Son...

Abstract Hydrokinetic turbines are an emerging technology to supply reliable and renewable energy by harnessing kinetic energy from river or tidal flows. They are a potential alternative to current hydropower schemes tha...

Nitrosomonas europaea is a chemolithoautotroph that obtains energy by oxidizing ammonia in the presence of oxygen and fixes CO2 via the Benson-Calvin cycle. Despite its environmental and evolutionary importance, very lit...

Abstract The confinement effect is increasingly recognized as a critical factor influencing guest–framework interactions in molecular sieves, yet its impact on adsorption kinetics remains largely unexplored. Convention...

Abstract Amine-functionalized solid adsorbents represent promising next-generation materials for efficient CO2 capture. However, their practical deployment is constrained by a fundamental trilemma balancing CO2 adsorptio...

Abstract The essential oil (EO) of Tanacetum argyrophyllum harvested from Armenian flora (2080 m above sea level), characterized by a eucalyptol–camphor chemotype, and was investigated for its antibacterial activity, ...

In an effort to explore environmentally friendly alternative energy solutions, this study develops a Speed Bump Generator system designed to generate electrical energy as a power source for garden lighting. The system ...

ABSTRACT In this study, the erosion of the nocturnal boundary layer (NBL) was analyzed in the central Amazon during the dry season of 2014, using data from the GoAmazon 2014/5 Project and high-resolution model outputs (P...

Protein recognition of DNA sites is a primary event for gene function. Its ultimate mechanistic understanding requires an integrated structural, dynamic, kinetic, and thermodynamic dissection that is currently limited co...

ABSTRACT The objective of this study was to evaluate the effects of mineral and protein-energy (MPES), exogenous fibrolytic enzyme supplements (ES), combination of MPES + ES, and straw without supplement (WS) on digestib...

The present work provides a parametric simulation tool to assist the experimental deposition of GaN and Ge-GaN material. For this purpose, a kinetic Monte Carlo (kMC) model was developed and implemented to simulate the d...

Aluminum (Al), a commonly used reactive metals, is widely applied in reactive material systems. However, its relatively low reactivity restricts the energy release of systems. To improve the reactivity of aluminum, we in...

Gymnopilus pampeanus (GP) is a mushroom consumed in Argentina. Spent Populus sawdust (SPS) obtained from the cultivation of GP was used to test methane production. The effect of two substrate/inoculums (S/I) ratios was a...

The search for new energy sources has intensified today worldwide. In Argentina, bioenergy continues to be the energy with minor participation in the energy matrix. Therefore, research should focus on searching for new s...
