A wear-resistant metal-organic framework membrane with a bioinspired scale-like structure has been developed for the efficient separation of propylene and propane. Credit: DICP Researchers developed a ...

Animal experiments ... any structure which has a membrane," Singh said. Take the electrolyte potassium, for example. It is the most abundant positively charged ion inside cells, but its ...

Bacterial cells differ fundamentally in their structure from animal and human cells. For example, bacteria have a rigid cell wall, whereas human cells are surrounded only by a simple membrane.

Scientists have succeeded in controlling the structure ... cross-membrane channels, created by DNA nanorobots, allows an efficient passage of certain molecules and substances into the cells.
