A Theoretical Study of Fe Adsorbed on Pure and Nonmetal (N, F, P, S, Cl)-Doped Ti3C2O2 for Electrocatalytic Nitrogen Reduction [PDF]

open access: yesNanomaterials, 2022
The possibility of using transition metal (TM)/MXene as a catalyst for the nitrogen reduction reaction (NRR) was studied by density functional theory, in which TM is an Fe atom, and MXene is pure Ti3C2O2 or Ti3C2O2−x doped with N/F/P/S/Cl. The adsorption

Association of Metallic and Nonmetallic Elements with Fibrin Clot Properties and Ischemic Stroke [PDF]

open access: yesLife
Objectives—Metallic elements and fibrin clot properties have been linked to stroke. We examined metallic and nonmetallic elements, fibrin clot lysis time (CLT), and maximum absorbance (Absmax) in relation to ischemic stroke.

Superlong‐Range Magnetic Coupling and Ferromagnetic Spin Freezing in Mechanoluminescent Semiconductor Eu:SrAl2O4 [PDF]

open access: yesAdvanced Science
Magnetic transition in nonmetals requires the presence of a considerable proportion of magnetic spins. A new type of ferromagnet named dilute ferromagnetism that contradicts this well‐established concept is proposed for semiconductors of ZnO etc. but has

Town scale response of water viral communities to town source surface water contamination with hydrochemical parameters [PDF]

open access: yesE3S Web of Conferences, 2023
This study aims to explore the relationship between human enteric viruses found in town-scale surface water sources and certain chemical contaminants present in the water. From October 2010 to April 2012, water samples were collected and analyzed using a

Electronic, Magnetic, and Optical Performances of Non-Metals Doped Silicon Carbide

open access: yesFrontiers in Chemistry, 2022
The configurations of nine different non-metals doped silicon carbide (NM-SiC) were structured by using the density functional theory (DFT). The magnetic, electronic, and optical properties of each NM-SiC are investigated at the most stable structure ...

Strike a Balance: Between Metals and Non-Metals, Metalloids as a Source of Anti-Infective Agents

open access: yesInorganics, 2021
Most of the commercially available anti-infective agents are organic molecules. In fact, though, during the pioneering times of modern medicine, at the beginning of the 20th century, several inorganic compounds of transition metals were used for ...

Handheld Laser-Induced Breakdown Spectroscopy for Field Archaeology: Characterization of Roman Wall Mortars and Etruscan Ceramics

open access: yesApplied Spectroscopy Practica, 2023
Handheld laser-induced breakdown spectroscopy (LIBS) was applied to two studies of archaeological material at excavation sites in the Orvieto (Umbria), Italy geographic region. The short analysis times and wide range of detectable elements, covering both

Carbon sequestration by afforestation and revegetation as a means of limiting net-CO2 emissions in Iceland. COST E21 Workshop. Contribution of forests and forestry to mitigate greenhouse effects. Joensuu (Finland). 28-30 Sep 2000 [PDF]

open access: yesBiotechnologie, Agronomie, Société et Environnement, 2000
Iceland has lost about 95/ of its woodlands and 50/ of its vegetative cover during the 1,100 years of human settlement. Efforts to reclaim lost woodlands and herbaceous ecosystems have been continuing since the early 20th century.
