Highly Active IrRuOx/MnOx Electrocatalysts with Ultralow Anode PGM Demand in Proton Exchange Membrane Electrolyzers

open access: yesAdvanced Energy Materials, EarlyView.
MnOx‐supported IrRuOx exhibits outstanding OER performance in both liquid electrolytes and real cell environments. The MnOx not only enhances the dispersion of IrRuOx but also induces a compressive strain effect. The incorporation of Ru leads to surface reconstruction.

Pareto-optimal treatment of uncertainties in model-based process design and operation [PDF]

open access: yesarXiv
Model-based process design and operation involves here-and-now and wait-and-see decisions. Here-and-now decisions include design variables like the size of heat exchangers or the height of distillation columns, whereas wait-and-see decisions are directed towards operational variables like reflux and split ratios.

Specially designed B4C/SnO2 nanocomposite for photocatalysis: traditional ceramic with unique properties [PDF]

open access: yesarXiv, 2017
Boron carbide: A traditional ceramic material shows unique properties when explored in nano-range. Specially designed boron based nanocomposite has been synthesized by reflux method. The addition of SnO2 in base matrix increase the defect states in boron carbide and shows unique catalytic properties.

Advantages of subtotal gastrectomy for upper third gastric cancer: A systematic review and meta‐analysis

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
We revealed that subtotal gastrectomy (STG) has its advantage over total gastrectomy on shorter operation time, less complication rates, and lower body weight loss by meta‐analysis. Although there are some controversies, STG can be an ideal option for patients with gastric cancer of upper third stomach.

A history of gastrectomy is a risk factor for choledocholithiasis in patients undergoing cholecystectomy: A single center retrospective study

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This retrospective study suggests that gastrectomy is a risk factor for choledocholithiasis. Especially in terms of the differences in reconstruction methods, the median time from gastrectomy to development of choledocholithiasis was 5.5 years for Roux‐en‐Y, which was significantly faster than 20 years for Billroth I and 35 years for Billroth II ...

Batch Extractive Distillation with Light Entrainer [PDF]

open access: yes, 2006
Use of a light entrainer in batch extractive distillation is justified when the mixture boils at a high temperature, or when an appropriate heavy or intermediate entrainer cannot be found.

Current status, trends, and controversies in the selection of gastrectomy procedures: Insights from two nationwide questionnaire surveys conducted over a 7‐year interval in Japan

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This study investigates the evolving trends and challenges in gastrectomy procedures in Japan, drawing on two nationwide surveys conducted in 2014 and 2021. Results show a significant shift toward minimally invasive and function‐preserving surgeries, such as laparoscopic and robot‐assisted gastrectomy, with an emphasis on enhancing postoperative ...
