Multiferroism in Pr_2FecrO_6 perovskite

引用

Journal of Rare Earths 2018年第11期36卷 1175-1178页

作者： s.ravi Department of Physics Mepco Schlenk Engineering College

Pr2FecrO6 perovskite crystallizes in an orthorhombic structure with R3c space group. Magnetic stuay nas revealed that Pr2FecrO6 exhibits room-temperature ferromagnetism with a curie temperature of about 562 K. Pr2FecrO6 also exhibits weak ferroelectricity. Thus, given its ferroelectric and ferromagnetic na- ture, the Pr2FecrO6 material can be considered as a multiferroic. In addition, due to its high curie temperature and multiferroicity, it could be a promising candidate for spintronics applications.

status and prospects for symmetric organic redox flow batteries

引用

Journal of Energy chemistry 2025年第1期100卷 125-143页

作者： Md Al Raihan c.Adam Dyker Department of chemistry University of New Brunswick

As environmental concerns from fossil fuel consumption intensify, large-scale energy storage becomes imperative for the integration of renewable sources like wind, hydro, and solar with the electrical *** flow batteries, particularly those employing organic molecules, are positioned as a key technology for this purpose. This review explores the growing field of symmetric organic redox flow batteries(ORFBs) within this context. Unlike traditional asymmetric designs based on unique active materials for each electrode, symmetric ORFBs involve a single bipolar species for both electrodes. This review highlights the benefits of a symmetric design, and categorizes five distinct classes of organic bipolar molecules used in both aqueous and non-aqueous solvents. By providing a comprehensive overview of their cell cycling and performance characteristics, the strengths and weaknesses of the diverse categories of bipolar molecules are highlighted for both solvent systems, as are opportunities for future development. This should guide new research directions and advance the development of practical symmetric ORFBs.

Plasma science and Technology 2004年第4期6卷 2411-2415页

A plasma-assisted catalytic reactor was used to remove nitrogen oxides (NOx)from diesel engine exhaust operated under different load conditions. Initial studies were focused onplasma reactor (a dielectric barrier discharge reactor) treatment of diesel exhaust at varioustemperatures. The nitric oxide (NO) removal efficiency was lowered when high temperature exhaust wastreated using plasma reactor. Also, NO removal efficiency decreased when 45% load exhaust wastreated. studies were then made with plasma reactor combined with a catalytic reactor consisting ofa selective catalytic reduction (scR) catalyst, V_2O_5/TiO_2. Ammonia was used as a reducing agentfor scR process in a ratio of 1:1 to NOx. The studies were focused on temperatures of the scRcatalytic reactor below 200℃. The plasma-assisted catalytic reactor was operated well to remove NOxunder no-load and load conditions. For an energy input of 96 J/l, the NOx removal efficienciesobtained under no-load and load conditions were 90% and 72% respectively at an exhaust temperatureof 100 ℃.

Welding of high strength low alloy steels (HsLA) involves usage of low, even and high strength filler materials (electrodes) than the parent material depending on the application of the welded structures and the availability of the filler material. In the present investigation, the fatigue crack growth behaviour of weld metal (WM) and heat affected zone (HAZ) regions of under matched (UM), equal matched (EM) and over matched (OM) joints has been studied. The base material used in this investigation is HsLA-80 steel of weldable grade. shielded metal arc welding (sMAW) process has been used to fabricate the butt joints. centre cracked tension (ccT) specimen has been used to evaluate the fatigue crack growth behaviour of the welded joints. Fatigue crack growth experiments have been conducted using servo hydraulic controlled fatigue testing machine at constant amplitude loading (R=0).A method has been proposed to predict the fatigue life of HsLA steel welds using fracture mechanics approach by incorporating influences of mismatch ratio (MMR) and notch location.

Proterozoic orogenic belts and rifting of Indian cratons: Geophysical constraints

引用

Geoscience Frontiers 2014年第1期5卷 25-41页

作者： D.c.Mishra M.ravi Kumar National Geophysical Research Institute (csIR) Gravity GroupHyderabad 500007 India Indian Institute of Geomagnetism Navi Mumbai 410218 India

The Aravalli-Delhi and satpura Mobile Belts （ADMB and sMB） and the Eastern Ghat Mobile Belt （EGMB） in India form major Proterozoic mobile belts with adjoining cratons and contemporary basins. The most convincing features of the ADMB and the sMB have been the crustal layers dipping from both sides in opposite directions, crustal thickening （ -45 km） and high density and high conductivity rocks in upper/ lower crust associated with faults/thrusts. These observations indicate convergence while domal type re- flectors in the lower crust suggest an extensional rifting phase. In case of the sMB, even the remnant of the subducting slab characterized by high conductive and low density slab in lithospheric mantle up to - 120 km across the Purna-Godavari river faults has been traced which may be caused by fluids due to metamorphism. subduction related intrusives of the sMB south of it and the ADMB west of it suggest N-s and E-W directed convergence and subduction during Meso-Neoproterozoic convergence. The simultaneous E-W conver- gence between the Bundelkhand craton and Marwar craton （Western Rajasthan） across the ADMB and the N-s convergence between the Bundelkhand craton and the Bhaodara and Dharwar cratons across the sMB suggest that the forces of convergence might have been in a NE sW direction with E-W and N-s compo- nents in the two cases, respectively. This explains the arcuate shaped collision zone of the ADMB and the sMB which are connected in their western part. The Eastern Ghat Mobile Belt （EGMB） also shows signatures orE -W directed Meso Neoproterozoic convergence with East Antarctica similar to ADMB in north India. Foreland basins such as Vindhyan （ADMB-sMB）, and Kurnool （EGMB） supergroups of rocks were formed during this convergence. Older rocks such as Aravalli （ADMB）, Mahakoshal-Bijawar （sMB）, and cuddapah （EGMB） supergroups of rocks with several basic/ultrabasic intrusives along these mobile belts, plausibly formed during an earlier episode of rifting during
