Photometric Diagnostic of the Sheath Dynamics and Electron Density Trends in Single and Dual Frequency CCRF Argon Plasmas

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT A methodological study is presented on a noninvasive photometric diagnostic for determining trends in electron density and sheath dynamics in single (1f) and a dual (2f) radio frequency capacitively coupled (CCRF) argon plasmas. The 1f discharges are operated at 13.56 and 27.12 MHz, respectively, while the 2f discharge is driven by both ...

Tuning Colloidal Stability and Photothermal Conversion Efficiency of Graphite Nanofluids via Anionic‐Nonionic Surfactant Engineering

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Graphite nanofluids were stabilized using a mixed SDS/Tween 80 surfactant system. The optimized formulation exhibited enhanced colloidal stability, red‐shifted UV–Vis absorption, and improved photothermal conversion under solar irradiation. Achieving stable dispersion of graphite flakes (GFs) in aqueous media remains a critical challenge in developing ...

Anterior cingulate cortex neuron subtypes differentially regulate seizures

open access: yesEpilepsia, EarlyView.
Abstract Objective This study aimed to investigate the regulatory roles of distinct neuronal subtypes within the anterior cingulate cortex (ACC) in acute seizures and to identify cell type‐specific mechanisms underlying seizure modulation in this region. Methods Acute seizure models were established in mice via pentylenetetrazol injection.

Genetic variants of EcPV2 E6 and E7 in equine genital and oronasal squamous cell carcinoma

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Since its discovery in 2008, equine papillomavirus type 2 (EcPV2) has been detected in up to 100% of equine genital and up to 40% of equine oronasal squamous cell carcinomas (SCCs). Preliminary sequence data point to the existence of EcPV2 E6 and E7 oncogene variants compared to the British reference sequence from 2008.

Nutraceutical Benefits of Anchomanes difformis Rhizome and Its Effects on Blood Glucose and Hepatorenal Function in Normoglycemic Rats

open access: yesFood Chemistry International, EarlyView.
Scientific analysis of Anchomanes difformis roots confirms significant nutraceutical potential, containing high levels of carbohydrates, proteins, and essential minerals. Phytochemical screening revealed antioxidants such as phenols and flavonoids, and although the extracts effectively lowered plasma glucose, safety testing showed dose‐dependent risks.

A STUDY OF THE PHOTOMETRIC VARIABILITY OF THE PECULIAR MAGNETIC WHITE DWARF WD1953−011 [PDF]

open access: yes, 2011
We present and interpret simultaneous new photometric and spectroscopic observations of the peculiar magnetic white dwarf WD1953−011. The flux in the V-band filter and intensity of the Balmer spectral lines demonstrate variability with the rotation ...

Plastic luminescence in mechanoluminescent composites

open access: yesInfoMat, EarlyView.
Through compression tests and numerical simulations, this study demonstrates that the luminescence of a mechanoluminescent (ML) composite is strongly associated with plastic strain, thereby providing new insight into deformation‐induced luminescence during the plastic stage.

Looking at Soil as It Is: Evolution of Microscopic Soil Characterization From Kubiëna to Artificial Intelligence

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
We provide a historic overview of microscopic soil structure characterization from its founding father, Walter Kubiëna, to several technical revolutions like automation, digitalization, and artificial intelligence. In addition to technical advancements, we explore how concepts and research questions have evolved in time.
