Abstract: Preparation of capped metal oxide nanocrystals comprising a metal oxide shell that are photocatalytically and thermally stable and their dispersions in monomers, oligomers, and polymers, as well as the resulting formulations and nanocomposite films. These nanocrystals are highly monodisperse with nanocrystal size between 3-100 n. Resultant formulations incorporating these nanocrystals and a matrix material are highly stable and result in nanocomposites that have high refractive index, are highly transparent, have minimal to no change in absorption upon thermal or UV processing and are optically transparent in the visible wavelengths with very little or no scattering.

Abstract: A method for producing crystalline α-Fe2O3 nanoparticles involving ultrasonic treatment of a solution of an iron (III)-containing precursor and an extract from the seeds of a plant in the family Linaceae. The method involves preparing an aqueous extract from the seeds of a plant in the family Linacae and dropwise addition of the extract to the solution of an iron (III)-containing precursor. The method yields crystalline nanoparticles of α-Fe2O3 having a spherical morphology with a diameter of 100 nm to 300 nm, a mean surface area of 240 to 250 m2/g, and a type-II nitrogen adsorption-desorption BET isotherm with a H3 hysteresis loop. A method for the photocatalytic decomposition of organic pollutants using the nanoparticles is disclosed. An antibacterial composition containing the crystalline α-Fe2O3 nanoparticles is also disclosed.

Abstract: A method for synthesizing an intergrown twin Ni2Mo6S6O2/MoS2 two-dimensional nanosheet with exposed (00L) crystal planes is disclosed. An Ni—Mo bonded precursor is formed by using an ion insertion method to restrict Ni ions to be located in a lattice matrix of a Mo-based compound; a dinuclear metal sulfide Ni2Mo6S6O2 is formed by precisely adjusting and controlling a concentration of a sulfur atmosphere and utilizing a reconstruction effect of Ni element in the lattice matrix of the Mo-based compound; and meanwhile, a growth direction of Ni2Mo6S6O2 is precisely adjusted and controlled by using a method for growing a single crystal in a limited area, so that Ni2Mo6S6O2 is grown, taking a single crystal MoS2 as a growth template, with the single crystal MoS2 alternately along a crystal plane (110) of the single crystal MoS2, so as to form a twin Ni2Mo6S6O2/MoS2 two-dimensional nanosheet in which Ni2Mo6S6O2 and MoS2 are intergrown.

Abstract: In accordance with the purpose(s) of the present disclosure, as embodied and broadly described herein, the disclosure, in one aspect, relates to compound Bi-poor perovskite crystals, methods for making the same, and ionizing and other electromagnetic radiation detectors constructed using the Bi-poor perovskite crystals. The Bi-poor perovskite crystals can be synthesized using melt-based growth methods and solution-based growth methods and contain no toxic heavy metals such as lead, cadmium, thallium, or mercury. Devices fabricated from the crystals maintain acceptable levels of performance over time. In some aspects, post-growth annealing can be used to improve the properties, including, but not limited to, room temperature resistivity and response to radiation.
