Unusual journey of migratory foreign bodies in the alimentary tract

Radiology Case Reports, 2023
Foreign bodies are uncommon, and the migration of ingested or inserted foreign bodies within or out of the gastrointestinal tract is even rarer. Migration of foreign objects from the digestive system to the soft tissue in the neck, genitourinary tract ...

Retained surgical sponges

The Bulletin of the Royal College of Surgeons of England, 2019
National guidance is in place to minimise the number of cases of surgical instruments and sponges retained in a patient post-surgery. But is the existing strategy for prevention sufficient? Is this supposed 'never event' always avoidable? George Winter investigates.

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes

Advanced Materials, EarlyView.
A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including
