Wet-chemical syntheses of quasi two-dimensional (2D) transition metal dichalcogenides (TMDs) have emerged as promising methods for straightforward solution-processing these materials. However, the photoluminescence (PL) properties colloidal TMDs are virtually unexplored due to typically nonemitting synthesis products. In this work, we demonstrate room temperature micro-PL delicate ultrathin WS2...

Microcapsules are commonly used in applications ranging from therapeutics to personal care products due their ability deliver encapsulated species through porous shells. Here, we demonstrate a simple and scalable approach fabricate microcapsules with shells by interfacial complexation of cellulose nanofibrils oleylamine, investigate the rheological properties suspensions resulting microcapsules...

Klockmannite copper selenide nanosheets (CuSe NSs) are synthesized by a facile microwave-assisted method and fully characterized. The nanosheets have smooth surface and hexagonal shape. The lateral size is 200-500 nm × 400-800 nm and the thickness is 55 ± 20 nm. The current-voltage characteristics of CuSe NS films show unique Ohmic and high-conducting behaviors, comparable to the thermally-depo...

Abstract Gravity affects colloidal dispersions via sedimentation and convection. We used dynamic light scattering (DLS) to quantify the mobility of nanoparticles on ground in microgravity. A DLS instrument was adapted withstand accelerations a drop tower, liquid handling set-up connected order stabilize temperature enable rapid cooling or heating. Light experiments were performed tower at ZARM ...

Magnetic cores of passive components are required to have low hysteresis loss, which is dependent on the coercive force. Since it is well known that the coercive force becomes zero at the superparamagnetic regime below a certain critical size, we attempted to synthesize Ni nanoparticles in a size-controlled fashion and investigated the effect of particle size on the magnetic properties. Ni nano...

In this work we have investigated the effect of solvent during processing SrFe12O19 platelet-based permanent magnets by cold sintering process (CSP) plus a post-thermal treatment. Several organic solvents: glacial acetic acid, oleic acid and oleylamine been analyzed, optimizing CSP temperatures at 190?270 °C, under pressures 375?670 MPa 6?50 wt% solvent. Modifications in morphological structura...
