Percutaneous endoscopic colostomy (PEC) has been established as an alternative method of intestinal decompression and irrigation for chronic intestinal pseudoobstruction, relapsing sigmoid volvulus, neurogenic bowel, and constipation [1]. However, the thin, distended colonic wall can easily be torn during creation of the PEC with the pull method, and inadvertent traction of the PEC tube and col...

Due to its direct band gap of ~1.35 eV, appropriate energy band-edge positions, and low surface-recombination velocity, p-type InP has attracted considerable attention as a promising photocathode material for solar hydrogen generation. However, challenges remain with p-type InP for achieving high and stable photoelectrochemical (PEC) performances. Here, we demonstrate that surface modifications...
