Direct tunneling through high-$\kappa$ amorphous HfO$_2$: effects of chemical modification [PDF]
We report first principles modeling of quantum tunneling through amorphous HfO$_2$ dielectric layer of metal-oxide-semiconductor (MOS) nanostructures in the form of n-Si/HfO$_2$/Al. In particular we predict that chemically modifying the amorphous HfO$_2$

Chemical Modification of Tylosin.
20-Homo tylosin, 20-nor tylosin, 20-deoxy-19,20-didehydro tylosin (6-vinyl tylosin) and 2",3"-didehydro-3"-deoxy tylosin were prepared by multi-step procedures. 20-Homo tylosin was about twice less active than tylosin while the other compounds exhibited very weak antibacterial activity.

Chemical Modification of Polysaccharides [PDF]
This review covers methods for modifying the structures of polysaccharides. The introduction of hydrophobic, acidic, basic, or other functionality into polysaccharide structures can alter the properties of materials based on these substances. The development of chemical methods to achieve this aim is an ongoing area of research that is expected to ...

Stretchable fabric generates electric power from woven thermoelectric fibers
Despite recent advances in flexible thermoelectric generators for wearable devices, current designs are unable to efficiently harvest heat flowing from human body. Here, the authors report high thermoelectric performance and stretchability in interlocked
