A sol-gel method for growing superconducting MgB2 films

, 2011
In this paper we report a new sol-gel method for the fabrication of MgB2 films. Polycrystalline MgB2 films were prepared by spin-coating a precursor solution of Mg(BH_4)_2 diethyl ether on (001)Al2O3 substrates followed with annealing in Mg vapor.

Reconstruction of active regular motion in amoeba extract: dynamic cooperation between sol and gel states.

PLoS ONE, 2013
Amoeboid locomotion is one of the typical modes of biological cell migration. Cytoplasmic sol-gel conversion of an actomyosin system is thought to play an important role in locomotion.

Entropic Elasticity at the Sol-Gel Transition

, 2001
The sol-gel transition is studied in two purely entropic models consisting of hard spheres in continuous three-dimensional space, with a fraction $p$ of nearest neighbor spheres tethered by inextensible bonds. When all the tethers are present ($p=1$) the

Silica Sol-Gel Entrapment of the Enzyme Chloroperoxidase

Journal of Nanotechnology, 2015
The enzyme chloroperoxidase (CPO) was immobilized in silica sol-gel beads prepared from tetramethoxysilane. The average pore diameter of the silica host structure (~3 nm) was smaller than the globular CPO diameter (~6 nm) and the enzyme remained ...
