In regenerative medicine, large supplies of safe and reliable human embryonic stem (hES) cells are needed for implantation into patients, but the field has faced challenges in developing cultures that can consistently grow and maintain clinical-grad…
From atomic crystals to spiral galaxies, self-assembly is ubiquitous in nature. In biological processes, self-assembly at the molecular level is particularly prevalent.
Phospholipids, for example, will self-assemble into a bilayer to form a cell…
Oil and water don’t mix, but add in some nanofibers and all bets are off.
A team of UCLA chemists and engineers has developed a new method for coating large surfaces with nanofiber thin films that are both transparent and electrically conductive…
Though many people have never heard of them, the emerging realm of micro-scale devices ? called microelectromechanical systems, or MEMS ? could completely change the medical, automotive and aerospace industries, except for one thing. No battery yet exists that will provide long-lasting power and still fit inside devices smaller than the width of a human hair. Bruce Dunn, a materials science professor from the UCLA Henry Samueli School of Engineering and Applied Science, believes a radical new design for a lightweight, rechargeable battery ? a design based on three-dimensional geometry ? will provide power to a host of devices so small that traditional batteries simply cannot be used.
