To enhance the total output energy and power of energetic materials, plasma that generated by electrically exploded metal wires was employed to initiate the detonation of energetic materials, thereby achieving the couple...

Abstract An integrated hydrochemical, statistical, and geospatial approach was adopted in the present study to evaluate the groundwater quality of the Mangura Nala watershed in the state of Bihar, India. A total of 154 g...

We report on a reversible structural phase transition of a two-dimensional system that can be locally induced by an external electric field. Two different structural configurations may coexist within a CO monolayer on Cu...

Background and purpose: Volumetric Interpolated Breath-hold Examination (VIBE) magnetic resonance imaging (MRI) can depict flap applicators of High-Dose-Rate (HDR) surface brachytherapy. Evaluating criteria for catheter ...

Droplets provide unique opportunities for the investigation of laser-induced surface chemistry. Chemical reactions on the surface of charged droplets are ubiquitous in nature and can provide critical insight into more ef...

Abstract Sudden stratospheric warmings (SSWs) can significantly impact tropospheric weather systems. Previous studies suggest that SSWs may also influence stratosphere‐to‐troposphere transport (STT), but their spatia...

Abstract Measurement the depth of ion implantation is considered to be one of the important subject in physics , which has been employed by using SIMS and RBS methods. In this research Electron spectroscopy of chemical A...

Context. Asteroseismology is a powerful tool used to infer the evolutionary status and chemical stratification of white dwarf stars and to gain insights into the physical processes that lead to their formation. This is p...

Abstract This paper initiates the systematic study of thermal field theory for generic equilibrium density matrices, which feature arbitrary values not only of temperature and chemical potentials, but also of average ang...

The most important theoretical and methodological aspects of studying chemistry in general secondary education institutions have been analyzed. To gain a deeper understanding of the challenges faced by secondary educatio...

Abstract Northwest Pacific sedimentary eolian dust flux records have long been used to make direct inferences about Asian interior aridity. However, factors other than aridity can impact dust production rate. We present ...

Abstract Key roles of marine dimethyl sulfoniopropionate (DMSP), dimethyl sulfide (DMS), methyl mercaptan (MeSH), and carbon disulfide (CS2) in the sulfur cycle and/or atmospheric chemistry, alongside the rapid environme...

Abstract Dehydration reactions in subducted slabs have long been correlated with embrittlement and intermediate‐depth earthquakes. However, the physical process of dehydration embrittlement remains unclear due to the c...

The temperature sensitivity of fine particulate matter (PM2.5) critically influences air quality and human health under a warming climate, yet models struggle to accurately reproduce observed sensitivities. This study im...

Abstract The recent cataloging of global microseisms benefits imaging of the Earth's interior with improved data coverage. Relying on the catalog, converted waves were extracted and employed to reveal variations of the m...

Abstract The chemical weathering of Earth's silicate rocks regulates the global climate. However, the exact role of continental weathering with orogenic building and island arc weathering with arc‐continent collisions ...

Fil: Labarca, Martín. Universidad Nacional de Quilmes; Argentina. Sobre la base del supuesto reduccionista según el cual la química puede ser reducida a la física fundamental, ella suele ser considerada una disciplin...
