Teaching and learning of laparoendoscopic hernia surgery in India: A challenge – problems and solutions

open access: yesInternational Journal of Abdominal Wall and Hernia Surgery, 2019
INTRODUCTION: One German surgeon (Eric Mühe in 1985)* and three French surgeons** (Philippe Mouret in 1987, Jacque Perissat in 1989, and Dubois F in 1990) are credited with having performed first* laparoscopic cholecystectomy and first** video-assisted ...

Confinement‐Induced Nonlocality and Optical Nonlinearity of Transdimensional Titanium Nitride Films in the Epsilon‐Near‐Zero Region

open access: yesAdvanced Optical Materials, EarlyView.
The epsilon‐near‐zero (ENZ) effect in metals emerges only in nanometer‐scale films with exceptional optical quality. Titanium nitride (TiN) films grown by molecular beam epitaxy retain high crystallinity down to 2 nm and exhibit dramatically enhanced nonlinear optical responses near the ENZ region.

Balancing Bulk Solution Chemistry and Cation Solvation for Stable Aqueous Aluminum Batteries

open access: yesAdvanced Science, EarlyView.
A dual‐scale electrolyte design balances bulk solution chemistry and cation solvation in aqueous aluminum batteries. Regulation of the bulk solution preserves high ionic conductivity and electrochemical stability, while modulation of the Al3+ solvation environment lowers desolvation penalties and suppresses hydrogen evolution. This balanced electrolyte

Endoscopic approach to recurrent inguinal hernia after previous open surgery

open access: yesJournal of Mind and Medical Sciences, 2023
Background. The management of a recurrent inguinal hernia varies depending on multiple factors. In the case of recurrent inguinal hernias after open anterior repair, the laparoscopic approach is recommended. TEP and TAPP procedures are considered to have

Subversion of Atypical Mucin Traps by a Spore‐Coat Effector Blocks Cellular Immunity in Drosophila

open access: yesAdvanced Science, EarlyView.
While the entomopathogenic fungus Metarhizium robertsii can evade insect humoral immunity, its subversion of cellular defenses is still elusive. We identify Eac1 as a spore‐coat protein essential for infecting drosophilids by targeting atypical mucins (Sgf1 and Sgf2), which can entrap spores in a gel matrix and thereby facilitate hemocyte encapsulation.

Effect of styrene acrylonitrile copolymer on the performance of TEP/PMMA composites

open access: yesMaterials Research Express, 2021
In this paper, TEP/PMMA composites system and SAN/TEP/PMMA composites system were prepared by in situ polymerization using methyl methacrylate (MMA), triethyl phosphate (TEP) and styrene acrylonitrile copolymer (SAN) as raw materials.

Metal Battery Anode: Rich in Electrons, Rich in Problems: A Critical Review from Industrial Perspectives

open access: yesAdvanced Science, EarlyView.
Metal‐anode batteries using Li, Na, Mg, and Ca offer exceptionally high energy density, but dendrites, unstable interphases, cracking, and pore formation hinder durability and safety. This review shows how careful electrolyte and interphase design can stabilize these reactive metals.

History of inguinal hernia repair, laparoendoscopic techniques, implementation in surgical praxis, and future perspectives: Considerations of two pioneers

open access: yesInternational Journal of Abdominal Wall and Hernia Surgery, 2021
Those who do not know the past cannot understand the present and cannot shape the future. (Helmut Kohl, Chancellor of Germany 1982–1998). INTRODUCTION: Historical development of open and laparoendoscopic inguinal hernia repair is presented.

Safety of Sodium‐Ion Batteries: Evaluation and Perspective from Component Materials to Cells, Modules, and Packs

open access: yesAdvanced Energy Materials, EarlyView.
This review provides a bottom‐up evaluation of sodium‐ion battery safety, linking material degradation mechanisms, cell engineering parameters, and module/pack assembly. It emphasizes that understanding intrinsic material stability and establishing coordinated engineering control across hierarchical levels are vital for preventing degradation coupling ...
