resection, which consists of not only resection of the involved organs but also simultaneous resection of the surrounding or adjacent mesenteries that contain lymph vessels and nodes. After resection of the diseased organs, the defect of the gastrointestinal conduit is replaced with organs located downstream, such as…
Preparation of samples for nuclear magnetic resonance (NMR) characterization of larger proteins requires enrichment with less abundant, NMR-active, isotopes such as 13C and 15N. This is routine for proteins that can be expressed in bacterial culture where low-cost isotopically enriched metabolic substrates can be used…
Abstract Herein, we report excellent corncobs‐derived carbon adsorbent by the special KOH chemical activation method which specific to selective adsorption removal of volatile organic chemicals (VOCs) under humid conditions. The obtained corncobs‐derived carbon adsorbent affords the enhanced adsorption removal capacit…
Abstract Water pollution abatement is a problem in today’s society that requires urgent attention. Moreover, photocatalysts are an effective method to treat environmental pollution, and SnO 2 /reduced graphene oxide composite photocatalysts have been extensively studied in recent years. The synthesis parameters for th…
A commercial i-DSI (Intelligent-Dual Sequential Ignition) engine is tested to investigate performance and emissions for single fuels and alternative fuels mixed into gasoline. The novelty of the study is the first time testing of the unconventional mixture of boron derivatives and quantification and comparison of real…
This article presents a high-conversion-ratio (HCR), high-voltage-tolerant (HVT) energy-harvesting battery charger using 0.18-μm standard CMOS for Internet of Things (IoT). To reduce conversion ratio (CR) of inductive power converter and optimize overall power efficiency, the proposed charger cascades a boost converte…
We report a rapid and easy method for the synthesis of silica nanoparticles (SiNps) from a liquid precursor. Specifically, plasma-enhanced chemical vapor deposition of a very small amount of a liquid precursor, tetraethoxysilane (300 μL), for a very short exposure time (5 min) resulted in the generation of dusty plasm…
Abstract Vanadium oxide has great potential in the development of battery technology. However, there are several key flaws, such as low rate performance and poor cyclic stability, that require urgent attention for such material. In view of these challenges, this work proposes a strategy to optimize the interlayer spac…
Summary Engineering and scaling-up nanocarriers for the controlled release of surfactant are imperative for enhanced oil recovery (EOR). Herein, using silica-based nanosized porous capsules to slowly release surfactant in saline water is reported. The results indicate that the silica shell ensures the stability of the…
A general analytical model, which is applied to pre‐estimate the air‐gap magnetic field of interior permanent magnet synchronous motors (IPMSM) under the no‐load and load conditions, is proposed in this study. First, the analytical formulas of both the slotless permanent magnetic field and the armature reaction magnet…
Ab initio nuclear magnetic resonance chemical shift prediction provides an important tool for interpreting and assigning experimental spectra, but it becomes computationally prohibitive in large systems. The computational costs can be reduced considerably by fragmentation of the large system into a series of contribut…
Thermophysical properties of liquid metal alloys play a crucial role in the variety of processes. Present work reports experimental investigations of two new transformation induced plasticity (TRIP) steels. A classical maximum bubble pressure technique is successfully used to measure surface tension and density of the…
To reduce the thickness of CuIn1‐xGaxSe2 (CIGSe) solar cells, light management concepts must be used. One concept is the combination of an Al/indium1‐tin1‐oxide (ITO) reflector/contact and an optical scattering element at the back side of the device. Herein, nanostructured substrates, obtained by laser interference li…
Abstract In this study, for the first time in the literature, synthesis of Au(0) nanoparticles supported by a crosslinked gel structure was performed via enzyme‐mediated reduction of Au(III) ions without using any chemical reductant. In our newly‐developed method, glucose oxidase enzymes immobilized in the crosslinked…
This paper focuses on the development of a thin normal-shear force sensor based on the use of a supercapacitive sensing mechanism. The sensor has a quad structure with four sensing units in which the bottom substrate has four pairs of electrodes while the top deformable portion has a solid-state electrolyte. The appli…
Development of noble metal nanostructure substrates that provide strong near-field enhancements enables applications of linear and nonlinear infrared (IR) spectroscopies to study minute sample quantities, such as nanometer thick films and molecular monolayers. Large near-field enhancements of the electric fields used…
Abstract We determine absolute reactivities for dissociation at low coordinated Pt sites. Two curved Pt(111) single‐crystal surfaces allow us to probe either straight or highly kinked step edges with molecules impinging at a low impact energy. A model extracts the average reactivity of inner and outer kink atoms, whic…
Hydrogen energy is a resuscitated clean energy source and its sensitive detection in air is crucial due to its very low explosive limit. Metal oxide decorated with noble metal nanoparticles has been used for the enhancement of gas detection and exhibits superior sensitivity. Understanding the intrinsic mechanism of th…
Direct current circuit breakers (DCCBs) have become a large research topic and are considered one of the critical components for future DC grids. Proposed DCCB concepts may be grouped into hybrid DCCBs and active resonant DCCBs. In this work, the enhanced active resonant (EAR) DCCB family is introduced. EAR DCCBs comb…
Two saddle‐shaped hole‐transporting materials (HTMs), α, β‐COTh‐Ph‐OMeTAD and β, β‐COTh‐Ph‐OMeTAD are designed with a strategy of flexible core with tunable conformation (FCTC) and applied in inverted planar perovskite solar cells (PSCs) as dopant‐free HTMs. As a result, the device based on α, β‐COTh‐Ph‐OMeTAD demonst…
