Resonant silicon nanoparticles for enhancement of light absorption and photoluminescence from hybrid perovskite films and metasurfaces.

Recently, hybrid halide perovskites have emerged as one of the most promising types of materials for thin-film photovoltaic and light-emitting devices because of their low-cost and potential for high efficiency. Further boosting their performance without detrimentally increasing the complexity of the architecture is critically important for commercialization. Despite a number of plasmonic nanoparticle based designs having been proposed for solar cell improvement, inherent optical losses of the nanoparticles reduce photoluminescence from perovskites.

[Transurethral electrosurgery of a new generation (TURis) in the treatment of the lower urinary tract and prostate diseases].

Surgical interventions were made in 175 patients aged 23-87 years (mean age 64.8 years) with different diseases of the lower urinary tract (adenoma, prostatic cancer, cancer of the urinary bladder, etc.) with application of a new generation of endoscopic technique--transurethral resection in saline (TURis system) with a generator UES-40 SurgMaster (Olympus).
