Effects of the ball-milling with LmNi4.1Al0.25Mn0.3Co0.65 alloy on the electrode characteristics of Ti0.32Cr0.43V0.25 alloy for Ni–MH batteries

High energy ball-milling preparation of Co–B amorphous alloy with high electrochemical hydrogen storage ability

“…Hydrogen storage alloys have been actively investigated as negative material of Ni/MH batteries [1,2]. In recent years, a series of Co-metalloid amorphous or nanocrystalline alloys, such as Co-B [3,4], Co-P [5][6][7], Co-S [8][9][10], Co-Si [11][12][13], Co-BH [14], Co-Si 3 N 4 [15] and Co-La 2 Mg 17 [16], have been prepared and used as the electrochemical hydrogen storage materials, which displayed large discharge capacity.…”

Ginsenoside Rp1 Exerts Anti-inflammatory Effects via Activation of Dendritic Cells and Regulatory T Cells

“…Many previous studies have indicated that red ginseng contains saponin components, such as ginsenoside Rh1 (G-Rh1), G-Rh2, G-Rg3, and G-Rg5, which all have anti-tumor activity in prostate cancer, ovarian cancer, and breast cancer [1-5]. Because these components are not stable, G-Rp1, which is a chemically stable component with ten-fold more potent anti-tumor activity than G-Rg3, has been derived from crude ginsenosides [6]. Kumar et al [7] documented the safety and effects of G-Rp1 on anti-tumor activity and demonstrated that G-Rp1-treated mice had a significant reduction in pathological symptoms in papillomagenesis.…”

Hydrogen storage and electrochemical characteristics of Ti0.32Cr0.43−V0.25Fe (x= 0–0.08) alloys and its composites with LmNi4.1Al0.25Mn0.3Co0.65 alloy

“…5 shows the discharge capacities of the Ti 0.32 Cr 0.43 − x V 0.25 Fe x (x = 0-0.08) alloy electrodes without AB 5 additives. Un-doped and Fe doped bcc alloys exhibited much lower discharge capacity than their theoretical values, which can be attributed to the formation of Ti-or V-rich oxide layers on the surface of the as-prepared alloys in a KOH solution, inhibiting the absorption of hydrogen during charging [21,22].…”

“…In previous studies, the catalytic activity and discharge capacity of bcc type Ti 0.32 Cr 0.43 V 0.25 alloy were improved either by ball-milling the alloy with the more active AB 5 type LmNi 4.1 Al 0.25 Mn 0.3 Co 0.65 (Lm: lanthanum-rich mischmetal) alloy [22][23][24][25] or by substituting Mn for Cr in the alloy and ballmilling it with an AB 5 type alloy [14]. The more active LmNi 4.1 Al 0.25 Mn 0.3 Co 0.65 (Lm: lanthanum-rich mischmetal) alloy was embedded in the surface of the Ti 0.32 Cr 0.43 V 0.25 base alloy through the ball-milling thereby forming a path for hydrogen penetration into the bcc alloy.…”
