TL;DR: In this paper, a co-precipitation method using hydroxypropyl cellulose (HPC) as dispersant was used to obtain nano-sized powders of YAG.
Abstract: Nd3+ doped yttrium aluminum garnet Y3Al5O12 (YAG) nano-sized powders were prepared by a co-precipitation method using hydroxypropyl cellulose (HPC) as dispersant. The formation process and structure of the as-prepared sample were investigated by means of TG–DTA, XRD, IR, and TEM. It has been found that the YAG powders were amorphous up to 700 °C and transformed into pure phase YAG crystallite at 900 °C for 2 h, because of the uniformly distribution of Al and Y elements. The size of YAG powder is about 30 nm in diameter and mono-disperse in the presence of HPC. Optical absorption and emission spectra of nano-crystallites versus Nd3+ concentration and sintering temperature were also studied.

TL;DR: In this article, an array of ferroelectric nanowires for photoelectrochemical (PEC) hydrogen production was demonstrated. And the poling bias was manipulated to tune the photocurrent density in the range from ca. 0.7 − 11.5 μA·cm−2 (at 0 −V vs. Ag/AgCl) under irradiation of air mass 1.5 global (AM 1 −1.5 G) full sunlight at 100 mW/cm2, while the onset potential switches from −0.32 to − 0.46

TL;DR: In this paper, the molar ratio of aluminum nitrate to ammonium aluminum sulfate has a significant effect on morphology and particle size of the precursor powders, and it was found that spherical precursor particles can be obtained when the ratio is 1:1.
Abstract: Monodispersed yttrium aluminum garnet (YAG) powders have been synthesized via homogeneous precipitation method from the mixed solutions of yttrium nitrate, aluminum nitrate, and ammonium aluminum sulfate using urea as the precipitant. The molar ratio of aluminum nitrate to ammonium aluminum sulfate has a significant effect on morphology and particle size of the precursor powders. It was found that spherical precursor particles can be obtained when the ratio is 1:1. During the homogeneous precipitation process, aluminum ions precipitate first and form monodispered spherical powders, and then yttrium ions precipitate onto the surface of the existing spheres. Monodispersed spherical YAG particles with 500 nm in diameter were obtained by calcining the precursor powder at 1100°C for 5 h. The so-prepared monodispersed spherical Nd:YAG powders have good sinterability, and can be sintered into transparent ceramics by vacuum sintering at 1650°C for 3.5 h.

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality. Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

TL;DR: This Review describes how the tunable electronic structure of TMDs makes them attractive for a variety of applications, as well as electrically active materials in opto-electronics.
Abstract: Ultrathin two-dimensional nanosheets of layered transition metal dichalcogenides (TMDs) are fundamentally and technologically intriguing. In contrast to the graphene sheet, they are chemically versatile. Mono- or few-layered TMDs - obtained either through exfoliation of bulk materials or bottom-up syntheses - are direct-gap semiconductors whose bandgap energy, as well as carrier type (n- or p-type), varies between compounds depending on their composition, structure and dimensionality. In this Review, we describe how the tunable electronic structure of TMDs makes them attractive for a variety of applications. They have been investigated as chemically active electrocatalysts for hydrogen evolution and hydrosulfurization, as well as electrically active materials in opto-electronics. Their morphologies and properties are also useful for energy storage applications such as electrodes for Li-ion batteries and supercapacitors.
