Control over morphology and crystallinity of metal halide perovskite films is of key importance to enable high-performance optoelectronics. However, this remains particularly challenging for solution-printed devices due to the complex crystallization kinetics of semiconductor materials within dynamic flow of inks. Here we report a simple yet effective meniscus-assisted solution printing (MASP) ...

Different physical vapor deposition methods have been used to fabricate strontium titanate thin films. Within the binary phase diagram of SrO and TiO2 the stoichiometry ranges from Ti rich to Sr rich, respectively. The crystallization of these amorphous SrTiO3 layers is investigated by in situ grazing-incidence X-ray diffraction using synchrotron radiation. The crystallization dynamics and evol...

An overview of the control of crystal properties in the crystallization of pharmaceutical solids will be presented. Two case studies will be considered: first, crystallization of stavudine with emphasis on the effect of process variables is investigated. Next, crystallization of paracetamol from water-isopropanol using a real-time optimal control will be discussed. The concentration and chord l...

In-situ alumina-zirconia composite bodies were fabricated by heat treatment of gibbsite-zircon-kaolinite mixture at 1450℃. The current research investigated crystallization behavior and mechanical properties of the mentioned mixture in the presence of 5 wt.% MgO as an additive. X-ray diffraction (XRD) results showed that alumina, zirconia, and magnesium aluminosilicate were crystallized during ...

The aim of this work is to investigate image processing and process monitoring technologies which can provide a systematic, robust and sensitive solution for nucleation detection using bulk video imaging (BVI). The external BVI method is based on a video camera and a capture hardware, which captures 25 frames of the crystallization bulk per second [1]. Another set of experimental data is genera...

Nanocomposites of renewable poly(ethylene furanoate) in situ filled with carbon nanotubes and graphene: effects on crystallization, semicrystalline morphology molecular dynamics.

The crystallization of membrane proteins in amphiphile-rich materials such as lipidic cubic phases is an established methodology in many structural biology laboratories. The standard procedure employed with this methodology requires the generation of a highly viscous lipidic material by mixing lipid, for instance monoolein, with a solution of the detergent solubilized membrane protein. This pre...

Single layers of WS2 nanoplates are uniformly embedded in nitrogen-doped carbon nanofibers (WS2@NCNFs) via a facile electrospinning method. Crystallization of the single-layered WS2 nanoplates and in situ nitrogen doping into the carbon nanofibers were simultaneously accomplished during a two-step heat treatment. The distinctive structure of the WS2@NCNFs enables outstanding electrochemical per...
