Transition-metal oxides constitute an important family of high-capacity anodes for Li-ion batteries. ZnO is a model material due to the high theoretical capacity and its representative reaction mechanism upon lithiation. We investigate the structural evolution, mechanical degradation, and stress-regulated electrochemical reactions of ZnO nanowires during the first lithiation through coordinated...

An electrode in a lithium-ion battery may undergo inelastic processes of two types: flow and reaction. Flow changes the shape of the electrode, preserves its composition and volume, and is driven by the deviatoric stress — a process similar to the plastic flow of a metal. By contrast, reaction changes the composition and volume of the electrode, and is driven by a combination of the mean stress...

OBJECTIVE The aim of this study was to assess the long-term impact of war captivity and combat stress reaction on rates of posttraumatic stress disorder (PTSD) in Israeli veterans of the 1973 Yom Kippur war. METHOD One hundred sixty-four former prisoners of war (POWs), 112 veterans who had had combat stress reaction, and 184 combat veteran comparison subjects filled out the PTSD Inventory, a ...

OBJECTIVE To measure oxidative stress in Type 1 leprosy reaction, and to document the effect of anti-leprosy multidrug therapy (MDT) and anti-reaction drugs on measures of oxidative stress. MATERIALS AND METHODS A prospective study was carried out at a teaching hospital involving consecutive patients with Type 1 reaction. MDA (malondialdehyde), FRAP (ferric reducing ability of plasma) and GSH...

In this paper, mixed convection flow of couple stress fluid in circular annulus is studied. First order chemical reaction, Soret and Dufour effects are taken into consideration. The governing partial differential equations are transformed into a system of ordinary differential equations and solved by Homotopy Analysis Method (HAM). The effects of Soret number, Dufour number, chemical reaction p...
