The columns have an inner solid silica impermeable core that is surrounded by an outer porous layer of silica which forms the outer shell. A big difference between fully porous and core-shell ...

The evolution of porous particle technology—including the development of core–shell and superficially porous particles—has significantly enhanced separation efficiency and reduced analysis time.

The particles in the columns are not fully porous but instead have a solid silica core surrounded by a porous outer layer. The very tight particle size distribution results in columns with high ...

Researchers have developed sub-micron silica particles that can be used to deliver compounds to restore damage to teeth and protect them from future damage.

Porous ceramics usually requires high mechanical strength and maximized porosity simultaneously, while for conventional particle grading strategy it is highly challenging to meet both demands. To ...

"With porous building blocks, controlling the link between porosity, particle size and mechanical properties is essential to the integrity of the system for any application," Shahsavari said.

Scientists use a Teflon pipe to make a cheap, simple reactor for silica particle synthesis Functional silica beads for biomedical imaging, drug delivery and other important applications could be ...

The patent was issued for the coacervation process used to manufacture the Poroshell 120 silica. The process applies the superficially porous shell to the particles in a single step, replacing a multi ...

Exactech announced today the expansion of its Truliant® Total Knee System with a new porous-coated implant option.

Researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University have developed a nanostructured silica-based “particle accelerator on a chip” which ...
