Pitting corrosion is one of the most destructive types of metal degradation and it can result in catastrophic failure of components due to transition of pits to stress corrosion cracks under loading. To facilitate the implementation of corrosion prognostics and health management, in paper presents a finite element app…
This paper reports a surface-mount flexible micro-supercapacitor employing a thin parylene-C membrane (10 μm) as the substrate and activated carbon (AC) as the electrodes. A thin parylene-C layer was deposited on a Si wafer by chemical vapor deposition (CVD) without silanization and then peeled off mechanically with t…
An important feature for graphene-based electronics is the ability to create a p-n junction, which is essential for developing low power optoelectronic and novel electronic devices such as Veselago lens and tunneling FETs. Graphene doping is most commonly achieved by using buried, split electrostatic gates1, applying…
This paper reports a novel ring-shape micro actuator for a latching mechanism used in a low power consumption and large displacement micro linear actuation. The proposed actuator consists of a shape memory alloy (SMA) ring, parylene spring and shoes. The parylene spring was carefully designed for independent control o…
Photolabile small interfering RNA (siRNA) oligonucleotide duplexes are becoming a powerful tool for photoregulation of gene expression through an RNA interference (RNAi) mechanism. Terminal or statistical labeling of siRNAs has been previously achieved. Recently, we have shown a new strategy for site-specific incorpor…
In order to perform the magnetic field computation it is essential to know the B-H characteristic. This paper presents a new equipment to be used to determine the first magnetization characteristic of a ferromagnetic body. This equipment consists of an 8-shape magnetic circuit, having as unknown the B-H magnetic chara…
This paper presents a tubing-free microfluidic wound healing assay to quantify the migration of vascular smooth muscle cells (VSMCs). In this study, gravity was used to generate a laminar flow within microfluidic channels, enabling wound formation of VSMCs in a tubing-free manner. The effects of channel geometries (i.…
In this study we have performed complete filling of through-silicon vias (TSVs) by supercritical carbon dioxide (sc-CO2)-enabled Cu electroplating process for applications in 3D ICs. The sc-CO2technique makes use of the special features of supercritical fluids, which combine benefits of different states of matter. The…
Tetrahedrites were recently discovered to be high-performance thermoelectrics but the chemical and structural origins of the rattling guests and resultant low thermal conductivity remain elusive. On page 3648, W. La and team establish a clear connection between the local bonding asymmetry and anharmonic rattling modes…
The urinary concentration level of bile acids is a useful indicator for the diagnosis of liver diseases. Here we present a sensor platform based on the anchoring transition of nematic liquid crystals (LCs) at the surfactant‐laden LC/aqueous interfaces for the detection of bile acids in urinary solution.
Physically bendable (flexible) solid state ferroelectric memory using PZT is demonstrated by M. M. Hussain and co-workers in article number 1500045. The device shows record endurance that is sustained for one billion operation cycles. Using a staged reactive ion etching process, silicon-substrate-based ferroelectric m…
Considering the objectives of based preventative maintenance strategy, condition monitoring of an MR M-type load tap changer (LTC) was assessed applying several oil analyses. The analyses consisted of dissolved gas analysis (DGA), breakdown voltage measurement as well as analyses of dissolved metals and suspended part…
We have developed highly durable achromatic polarizer by controlling the light absorption of side chains in the chemical structure of dichromatic pigment molecules and the physical cross‐linked structure of polyvinyl alcohol film, which led to the realization of low power monochrome‐type reflective LCD with high refle…
Y. Yu and colleagues develop a surfactant-assisted assembly method to fabricate 3D nanoarchitectures in which Sn-based nanoparticles are encapsulated by a porous graphene network. The novel nanostructure design presented on page 3488 offers the necessary void space for the expansion of active particles, preventing the…
The transmission high electron energy diffraction (THEED) technique was employed for studying the structure of the equimolar Ar–Kr alloy, in which the thermodynamics predicts the maximum feasibility of phase separation. Deposition of preliminarily cooled gas mixtures was performed onto substrates cooled to 6 or 20 K.…
Considerable numbers of glass, ceramic and non-ceramic insulators strings are used on transmission and distribution overhead lines. Defects that commonly occur on this type of high voltage equipment are often associated with the presence of the corona discharges or gap discharges and therefore could be diagnosed using…
AlGaN/GaN metal-oxide-semiconductor high electron mobility transistors (MOS-HEMTs), grown on the Si substrate, with high-k TiO2gate dielectric (k = 53.6) formed by using non-vacuum ultrasonic spray pyrolysis deposition (USPD) method has been investigated. Pulse I-V and low-frequency noise spectra (1/f) are conducted t…
Abstract One of the fundamental biochemical characteristics of Alzheimer′s Disease (AD) is the intercellular accumulation of amyloid beta (Aβ) peptide plaques in the brain. Although there is not yet a cure for AD, major efforts have been made to identify antiamyloidogenic agents and therapeutic strategies to treat thi…
The experimental setup for obtaining and determination of the thermal conductivity of simple van der Waals crystal-based nanocomposites is described. Preliminary thermal conductivity results of measurements carried out in the temperature range 1–40 K on two samples of methane crystals containing nanoparticles of hydro…
The influence of the types and regimes of heat treatment, as well as of the temperature and magnitude of the shape-memory-inducing deformation on the structural changes, martensitic transformations, parameters of the crystal lattice and substructure, and the mechanical and thermomechanical characteristics have been st…
