TL;DR: In this article, the spectral photovoltage in nanocrystalline porous nanoparticles is investigated, which belongs to a class of materials with a very low electrical conductivity, i.e., with a huge Maxwell relaxation time.

TL;DR: In this article, free charge carriers in mesoporous Si (meso-PS) consisting of Si nanocrystals of small dimensions of about 6-10 nm were investigated by the infrared-absorption technique.

TL;DR: In this article, the authors presented a highly explosive binary system based on porous silicon layers with their pores filled with solid oxidizers, which is completely compatible with the standard silicon technology and full bulk silicon wafers can be processed and therefore a large number of explosive elements can be produced simultaneously.

TL;DR: In this article, the quenching of the exciton photoluminescence of silicon nanocrystals has been shown to decrease the number of cancer mouse fibroblast cells when they come into contact with photoexcited silicon nanoparticles.

TL;DR: In this paper, the authors investigated the use of nanoparticles for ultrasound-assisted therapy of cancer cells in vitro and in vivo, and found that the nanoparticles were almost nontoxic up to the concentration of 0.1 µmg/mL and doses of 30 µg/kg, respectively.
