Practical applications of CsPbX3 nanocrystals (NCs) are limited by their poor stability. The formation a heterojunction between NCs and oxides is an effective means to protect perovskite from polar solvents other external factors. Significantly improving the stability photocatalytic properties core/shell very important for its application in photoelectric technology. Here, we report synthesis a...

atorvastatin calcium, the lipid lowering agent, is taken as a model drug characterized by poor water solubility and bioavailability. in this study an attempt was made for preparation of nanocrystals using high pressure homogenization. a number of stabilizers were included as well as polymers at different concentrations, and the formulations were homogenized for ten cycles at a pressure of 1000 ...

In this study, colloidal germanium nanocrystals were synthesized by a simple and novel method, and their optical properties were also studied. Polyvinyl alcohol (PVA) as a surface modifier was used to control the optical properties of colloidal Ge nanocrystals. Fourier transform infrared spectroscopy (FTIR) analysis was performed to identify the various functional groups present in the sample. ...

In this work we present the design, assembly and characterization of a tandem photoelectrochemical (PEC) cell based on two different crystallographic phases sub-stoichiometric copper telluride nanocrystals (NCs). The first one, pseudo-cubic phase, pc-Cu2-xTe, is characterized by positive photocurrents, while second hexagonal h-Cu2-xTe, favors negative ones. Taking advantage optoelectronic prope...

Halide perovskites are extremely interesting semiconductors for innovation in optoelectronics and photovoltaics. In particular, they efficient emitters of both incoherent coherent light and, therefore, interest as active materials lasers, amplification systems (resonators waveguides), other photonic devices. Here, we present a set experimental results concerning nonlinear effects the radiative ...

We herein propose a proof of concept full dual-band electrochromic (EC) device able to selectively modulate solar light between 300 and 1600 nm. Dual-band control was achieved by exploiting the complementarity cooperation two earth-abundant nontoxic transition metal oxide nanocrystalline materials absorb different spectral regions when electrochemically charged. The active were obtained through...

In this study, the enhanced photodegradation of a high-concentration phenol red (PR) using very fine TiO2 nanocrystals by adding KBrO3 electron acceptor was reported for first time. The structural study on HRTEM, XRD, Raman, and EDX performed it confirmed anatase phase nanocrystals. UV–Vis absorbance 20 mg.L?1 PR measured extracted. concentration effects exhibited an important enhancement in de...
