Nanotechnology for composites: Design, simulation, and applications
A new book reviews the recent progress in application of engineered nanopolymer and nanoparticles and their composites. The advantages and disadvantages of different methods are discussed.
Nanoparticles could make big impact for patients in need of cornea transplant
Animal study shows that a nanoparticle applied at the time of surgery slowly releases needed medicine to reduce risk of rejection after eye surgery.
Optical microfibres light the way for brain-like computing
Computers that function like the human brain could soon become a reality thanks to new research using optical fibres made of speciality glass.
Scientists have found a way to make the strongest spider silk fibers
Researchers have produced the strongest spider silk fiber so far. Given the good properties of this new material, this silk can be used for regenerative medicine.
Hydrocarbon photocatalysts get in shape and go for gold
A combination of semiconductor catalysts, optimum catalyst shape, gold-copper co-catalyst alloy nanoparticles and hydrous hydrazine reducing agent enables an increase of hydrocarbon generation from CO2 by a factor of ten.
