We present a dip-coatable, high-capacitance ion gel dielectric for scalable fabrication of three-dimensional (3D) electrowetting-on-dielectric (EWOD) devices such as an n × n liquid prism array. Due to the formation of a nanometer-thick electric double layer (EDL) capacitor, an ion gel dielectric offers two to three orders higher specific capacitance (c ≈ 10 μF/cm²) than that of conventional di...

Protective coating corrosion failure is a complicated process that involves various phenomena which are hard to test for separately. An adequately protected pipe can be in service for a relatively long time without exhibiting any signs of corrosion failure, and then all of a sudden it corrodes over a short period of time. Failure will definitely happen if the interface between the pipe surface ...

In this paper, we show a general way to interpret the infrastructure of a global field of arbitrary unit rank. This interpretation generalizes the prior concepts of the giant-step operation and f -representations, and makes it possible to relate the infrastructure to the (Arakelov) divisor class group of the global field. In the case of global function fields, we present results that establish ...

In this study, LiFePO4/C is synthesized via a novel two-step method. The first step is the synthesis of nano-sized intermediate FePO4 by a modified sol–gel method. A fast and full combustion procedure is involved to remove carbon and control the size of the intermediate particles. The second step is to prepare LiFePO4/C by combining solid-state reaction with controllable carbon coating. This tw...

We discuss the nonabelian world-volume action which governs the dynamics of N coincident Dp-branes. In this theory, the branes’ transverse displacements are described by matrix-valued scalar fields, and so this is a natural physical framework for the appearance of noncommutative geometry. One example is the dielectric effect by which Dp-branes may be polarized into a noncommutative geometry by ...

Definable surface chemistry is essential for many applications of microfluidic polymer systems. However, small cross-section channels with a high surface to volume ratio enhance passive adsorption of molecules that depletes active molecules in solution and contaminates the channel surface. Here, we present a one-step photochemical process to coat the inner surfaces of closed microfluidic channe...

The aim of this study was to develop an alternative method for enteric coating of HPMC capsules that avoids the sealing step before coating, resulting in ready-to-use enteric-coated capsules for the use in retail or hospital pharmacy or R&D sections of pharmaceutical industry and for the production of enteric-coated heat and moisture sensitive biomaterials. HPMC caps and bodies 00 (Vcaps, Capsu...

Spin-coating, one of Philips’ widespread wet-chemical coating technologies, is sensitive to substrate inhomogeneities. That leads sometimes to coating imperfections that are much larger than their causes. In order to understand how some of these imperfections affect the coating procedure, some experiments are going to be studied. In this case, a gravity-driven set-up will be used. The phenomeno...

Metal halide perovskite, a promising semiconductor material, is suitable for new generation optoelectronic application. In comparison to organic -inorganic hybrid perovskites (OIHP), all inorganic CsPbX3 (X = Cl, Br and I) show superior thermal chemical stability. Although there are many kinds of coating procedures producing perovskite QDs peorovskite film, most studies thin film fabrication fo...
