Pd(II)-Catalyzed C-H Acylation of (Hetero)arenes. Recent Advances
(MDPI, 2020-07-16)
Di(hetero)aryl ketones are important motifs present in natural products, pharmaceuticals or agrochemicals. In recent years, Pd(II)-catalyzed acylation of (hetero)arenes in the presence of an oxidant has emerged as a catalytic ...
Exilic Ecologies
(MDPI, 2023-10-09)
A term of relatively recent mintage, coined by German scientist Ernst Haeckel in 1866, ecology draws on ancient Greek to establish and consolidate its meaning. Although scholars all too often overlook it, the anachronistic ...
A trade-off between ligand and strain effects optimizes the oxygen reduction activity of Pt alloys
(RSC, 2022-10-20)
To optimize the performance of catalytic materials, it is paramount to elucidate the dependence of the chemical reactivity on the atomic arrangement of the catalyst surface. Therefore, identifying the nature of the active ...
Non-Excitatory Amino Acids, Melatonin, and Free Radicals: Examining the Role in Stroke and Aging
(MDPI, 2023-10-10)
The aim of this review is to explore the relationship between melatonin, free radicals, and non-excitatory amino acids, and their role in stroke and aging. Melatonin has garnered significant attention in recent years due ...
Modeling the Effector - Regulatory T Cell Cross-Regulation Reveals the Intrinsic Character of Relapses in Multiple Sclerosis
(Biomed Central, 2011-07-15)
Background: The relapsing-remitting dynamics is a hallmark of autoimmune diseases such as Multiple Sclerosis (MS). Although current understanding of both cellular and molecular mechanisms involved in the pathogenesis of ...
Interventions for the Development of Intrinsic Motivation in University Online Education: Systematic Review—Enhancing the 4th Sustainable Development Goal
(MDPI, 2023-06-21)
Background: The development of quality education, as stated by the United Nations in the 4th Sustainable Development Goal of the 2030 Agenda, is a very relevant aspect to work on, and specifically, motivation can play an ...
Selecting optimal R6TX2 intermetallics (R = Gd, Tb, Dy; T = Mn, Fe, Co, Ni; X = Sb, Te) for magnetic refrigeration
(Royal Society of Chemistry, 2023-03-20)
A complete experimental study of the physical properties playing a relevant role on magnetic refrigeration application (structural, magnetic, magnetocaloric and thermal) has been performed over nine selected Fe2P-type R6TX2 ...
Peculiar magnetocaloric properties and critical behavior in antiferromagnetic Tb3Ni with complex magnetic structure
(Elsevier, 2019-08-12)
A study on the magnetocaloric properties of a Tb3Ni single crystal (which crystallizes in the orthorhombic Pnma space group) has been undertaken and combined with the study of the character and critical behavior of its ...
Effect of Nd doping on the crystallographic, magnetic and magnetocaloric properties of NdxGd3-xCoNi
(AIP Publishing, 2023-06-05)
The crystal structure, magnetic and magnetocaloric properties, and the critical behavior of representative compounds in the pseudo-ternary NdxGd3-xCoNi series have been investigated (x = 0.15, 0.5, 1.0, 1.5). All these ...
Magnetocaloric properties, magnetic interactions and critical behavior in Ho6(Fe,Mn)Bi2 intermetallics
(Elsevier, 2020-02-08)
Four polycrystaline Fe2P-type Ho6(Fe,Mn)Bi2 intermetallic compounds (space group , No. 189, hP9) have been studied using magnetic techniques in order to explore their ability as magnetocaloric materials, and study the ...
