Laparoscopic distal partial gastrectomy is still technically difficult under conditions of a pneumoperitoneum because the lack appropriate techniques and laparoscopic instruments. We describe here technique laparoscopy-assisted Billroth I an abdominal wall-elevating method.
Beyond the fragile glass fiber separator, we demonstrated a polymer separator with good mechanical strength and fast Zn 2+ diffusivity, which synergistically mitigates dendrite formation improves reversibility at high capacity.
Iridium oxide (IrOx)-based materials are the most suitable oxygen evolution reaction (OER) catalysts for water electrolysis in acidic media. There is a strong demand from industry improved performance and reduction of Ir amount. Here, we report composite catalyst, IrOx–TiO2–Ti (ITOT), with high concentration active OH species mixed valence IrOx on its surface. We have discovered that obtained ITOT catalyst shows an outstanding OER activity (1.43 V vs RHE at 10 mA cm–2) Moreover, no apparent...

Aluminum solid polymer capacitors are promising devices for the increased demand power electronics applications. Nonetheless, low breakdown voltage of commercially available catalysts (∼100 V) limits their In this study, a hydroxide-film-covered high-purity aluminum was anodized at 700 V in boric acid 85 °C, and effect second hot water immersion (posthydration treatment) after anodizing on studied as possible future treatment to enhance withstand voltages electrolytic capacitors.

Highly efficient mixed H+/e–/O2– triple conducting air electrodes are indispensable for improving the electrochemical performance of protonic ceramic fuel cells and electrolysis (PCFC/ECs) operating at intermediate temperatures. This study demonstrates that single perovskite-type La0.8Sr0.2Co1-xNixO3-δ families (LSCN, x = 0–0.3) conductors due to a pronounced hydration ability elevated temperatures with related enthalpy −107 kJ mol–1. Thermogravimetry confirmed oxides were capable 0.01 mole...
The reaction pathway of the oxygen reduction (ORR) is strongly affected by electrolytic environment. Meanwhile, ORR mechanism on transition-metal oxide catalysts has not been studied intensely in very concentrated alkaline solutions that are used practical metal–air batteries. Herein, we report situ activation catalysis manganese perovskite a solution, mediated spontaneous formation vacancy sites. Electrochemical analyses (100) epitaxial film electrodes reveal exchange current and electron...
A simple anodizing technique has been employed to develop highly active electrocatalysts that can be applied the oxygen evolution reaction (OER) in alkaline media. NiFe alloys were electrodeposited and anodized form a porous electrocatalytic layer. This approach produces electrodes without need for noble metals, binders, or conductive carbon additives. The as-anodized electrode initially exhibits poor OER activity 1.0 mol dm–3 KOH; however, effects of potential cycling improve an extent...

Abstract Rechargeable aqueous zinc (Zn)‐ion batteries (RAZIBs), which use non‐flammable electrolytes and low‐cost electrode materials, show great potential to boost the development of safe, cost‐effective, highly efficient energy storage systems. The adoption lightweight inexpensive aluminum (Al) as current collectors seems be a good vision, but Al exhibits an easily‐corroded nature high impedance in electrolytes, making it challenge realize utilization collector RAZIBs.

Abstract A safe and straightforward process was developed for electropolishing aluminum surfaces using a nonhazardous electrolyte solution, specifically ethylene glycol (EG) or propylene (PG) with NaCl, instead of perchloric acid. High-purity specimens were immersed in slowly stirred solution EG PG NaCl anodically polarized at 20–140 V 2–30 min. At an optimal voltage 40–60 V, the current density reached constant value after initial transition, resulting uniform dissolution specimen’s surface...
