Ag-Modified Cu Foams as Three-Dimensional Anodes for Rechargeable Zinc–Air Batteries (2019)

Rechargeable zinc–air batteries are typical environment-friendly energy storage devices with high energy density and low cost. Nevertheless, dendrite formation and self-corrosion of zinc anode directly reduce battery performance. Herein, we report a novel Cu foam substrate with uniform Ag nanoparticles deposited on the surface as three-dimensional (3D) anode in rechargeable zinc-air battery and battery stacks for the first time. Tafel and linear scanning voltammetry measurements exhibit the Ag deposited on Cu foam suppresses hydrogen evolution reaction and reduces corrosion current density on the anode. Ag-modified three-dimensional anode is used in a primary zinc-air battery with 200 mAh anode capacity and Ag–Cu catalyzed cathode, which demonstrates a high specific capacity of 676 mAh gZn–1, an energy density of 786 Wh kgZn–1 and a high zinc utilization of 87%. Afterward, Ag-modified three-dimensional anode is used in a rechargeable zinc–air battery, which presents a Coulombic efficiency of 94% after 80 cycles with 2 h cycle period. Besides, Ag-modified three-dimensional anode is free of Zn dendrites at different depth of discharge from 5% to 20%. When two rechargeable zinc–air batteries are connected in both series and parallel, these batteries show a high energy efficiency of 55% and 60%, respectively, and deliver stable cycling over 40 cycles. The stable cycling performance can be attributed to Ag nanoparticles on the substrate surface, which regulate the Zn deposition uniformly in the voids between Cu foam skeleton and prevent dendrite formation by providing continuous uniform electronic transmission channels.

Novel association of the obesity risk-allele near Fas Apoptotic Inhibitory Molecule 2 (FAIM2) gene with heart rate and study of its effects on myocardial infarction in diabetic participants of the PREDIMED trial (2014)

We confirmed the FAIM2-rs7138803 relationship with obesity and identified novel and consistent associations with heart rate in particular in type 2 diabetic subjects. Furthermore, our results suggest a possible association of this polymorphism with higher myocardial infarction risk in type-2 diabetic subjects, although this result needs to be replicated as it could represent a false positive.
Application of the Fourier transformation to flutter tests (1994)

Hammond and Doggett (1976) present the method for determination of a damping coefficient of vibrations in flutter tests in terms of the Fourier transformation. The invented formula for the damping coefficient is complex and demands for many simplifications to be accepted when producing it. It has been proved in the present contribution that the plain and precise formula for the damping coefficient can be invented without any simplifications when employing the Fourier transform. This method has been tested both on the model and the experimental data. It is currently being used in the analysis of flutter characteristics of an aircraft in flight.
3-D seismic evidence of the effects of carbonate karst collapse on overlying clastic stratigraphy and reservoir compartmentalization (1996)

Abstract A multidisciplinary team, composed of stratigraphers, petrophysicists, reservoir engineers, and geophysicists, studied a portion of Boonsville gas field in the Fort Worth Basin of north-central Texas to determine how modern geophysical, geological, and engineering techniques can be combined to understand the mechanisms by which fluvio-deltaic depositional processes create reservoir compartmentalization in a low- to moderate-accommodation basin. An extensive database involving well logs, cores, production, and pressure data from more than 200 wells, 26mi2 (67 km2) of 3-D seismic data, vertical seismic profiles (VSPs), and checkshots was assembled to support this investigation. We found the most important geologic influence on stratigraphy and reservoir compartmentalization in this basin to be the existence of numerous karst collapse chimneys over the 26-mi2 (67 km2) area covered by the 3-D seismic grid. These near-vertical karst collapses originated in, or near, the deep Ordovician-age Ellenburger carbonate section and created vertical chimneys extending as high as 2500 ft (610 m) above their point of origin, causing significant disruptions in the overlying clastic strata. These karst disruptions tend to be circular in map view, having diameters ranging from approximately 500 ft (150 m) to as much as 3000 ft (915 m) in some cases. Within our study area, these karst features were spaced 2000 ft (610 m) to 6000 ft (1830 m) apart, on average. The tallest karst collapse zones reached into the Middle Pennsylvanian Strawn section, which is some 2500 ft (760 m) above the Ellenburger carbonate where the karst generation began. We used 3-D seismic imaging to show how these karst features affected the strata above the Ellenburger and how they have created a well-documented reservoir compartment in the Upper Caddo, an upper Atoka valley-fill sandstone that typically occurs 2000 ft (610 m) above the Ellenburger. By correlating these 3-D seismic images with outcrops of Ellenburger karst collapses, we document that the physical dimensions (height, diameter, cross-sectional area) of the seismic disruptions observed in the 3-D data equate to the karst dimensions seen in outcrops. We also document that this Ellenburger carbonate dissolution phenomenon extends over at least 500 mi (800 km), and by inference we suggest karst models like we describe here may occur in any basin that has a deep, relatively thick section of Paleozoic carbonates that underlie major unconformities.
A New Class of Modular Phosphinite–Oxazoline Ligands: Ir-Catalyzed Enantioselective Hydrogenation of Alkenes We thank Dr. Martin Studer and Dr. Benoît Pugin (Solvias AG, Basel) for fruitful discussions, and Prof. Kevin Burgess (Texas A&M University) for preprints of related unpublished work. Financial support by the Swiss National Science Foundation is gratefully acknowledged. (2001)

Both enantiomers are readily prepared of phosphinite–oxazoline ligands 1 from the D and L enantiomers of serine (see Scheme). Iridium complexes derived from these ligands (the structure of one complex is shown) are excellent catalysts for the enantioselective hydrogenation of unfunctionalized alkenes.

Resistive‐switching mechanism of transparent nonvolatile memory device based on gallium zinc oxide (2011)

Abstract We report an indium‐free transparent resistive switching random access memory (TRRAM) device based on a gallium‐doped zinc oxide (GZO)‐Ga 2 O 3 ‐ZnO‐Ga 2 O 3 ‐GZO structure grown by metal‐organic chemical vapor deposition. The bipolar resistive‐switching behavior is investigated based on the filament model. ZnO insulator layer fabricated at different temperature are compared to further support the filament mechanism. The compliance current applied on the device is changed from low to high to study the properties of conductive filaments in ZnO. The Joule‐heating effect is also studied by adjusting the integrating time in voltage sweeping.
The implication of dynamic monitoring of α1-acid glycoprotein and high-sensitivity C-reactive protein to assess the severity of acute pancreatitis in the early stage (2010)

Objective To explore the value of dynamic monitoring of serum α1-acid glycoprotein (α1-AGP)and high-sensitivity C-reactive protein (HsCRP) to assess the severity of acute pancreatitis in the early stage.Methods Seventy-four cases of acute pancreatitis(AP)(23 cases of severe AP and 51 cases of mild AP)at post-admission were detected dynamically for serum α1-AGP,HsCRP,and received APACHE Ⅱ scoring and enhanced CT examination.The results were comparatively analyzed.Results The changes in α1-AGP and HsCRP levels at the same time between severe group and mild group during hospitalization showed statistically significant difference (P<0.01).α1-AGP concentrations detected at 24 h after admission to assess AP severity and APACHE Ⅱ score had a better goodness of fit(P<0.01).α1-AGP and HsCRP levels detected at the 3rd day after admission and APACHE Ⅱ score had an excellent goodness of fit(P<0.01).Conclusion α1-AGP and hsCRP can be used as indicators to assess the changes in the illness conditions of the AP patients,and predict the severity of AP in the early stage well.

A new giant magneto-impedance head using magnetic microstrip lines (1998)

The performance of a novel magneto-impedance (MI) sensor head is described. The sensor is based on a magnetic microstrip line whose transmission impedance changes due to the permeability variation induced in the magnetic strip by external fields. The effects of device geometry on the performance is examined. It is found that output signal increases with both higher carrier power and narrower strip width. A microsensor with magnetic strip dimensions of 5/spl times/20 /spl mu/m demonstrated a high sensitivity of 6 mv/sub pp//Oe and a broad bandwidth of 300 MHz at an input power of 1 mW.
Computational Cardiology: The Heart of the Matter (2012)

This paper reviews the newest developments in computational cardiology. It focuses on the contribution of cardiac modeling to the development of new therapies as well as the advancement of existing ones for cardiac arrhythmias and pump dysfunction. Reviewed are cardiac modeling efforts aimed at advancing and optimizing existent therapies for cardiac disease (defibrillation, ablation of ventricular tachycardia, and cardiac resynchronization therapy) and at suggesting novel treatments, including novel molecular targets, as well as efforts to use cardiac models in stratification of patients likely to benefit from a given therapy, and the use of models in diagnostic procedures.
The PilA protein of non‐typeable <i>Haemophilus influenzae</i> plays a role in biofilm formation, adherence to epithelial cells and colonization of the mammalian upper respiratory tract (2007)

We recently described the expression of type IV pili (Tfp) by non-typeable Haemophilus influenzae (NTHI), a common respiratory tract pathogen. Prior to that report, Tfp were not thought to be produced by NTHI as they are not observed on NTHI when grown on chocolate agar or other commonly used growth media. To further characterize growth conditions permissive for the expression of NTHI Tfp, as well as determine their role in colonization and virulence, we transformed an NTHI otitis media isolate with a reporter plasmid containing the lux gene cluster driven by the pilA promoter. Transcription from the pilA promoter was demonstrated under a variety of in vitro growth conditions and, importantly, by ex vivo imaging of luciferase-producing NTHI in infected chinchillas. Luciferase-producing NTHI were also identified within a biofilm formed by NTHI in vivo. We further demonstrated a role for NTHI PilA in adherence to human respiratory epithelial cells, in colonization of the chinchilla respiratory tract as well as a requirement for PilA in biofilm development, both in vitro and in vivo. Collectively, our data demonstrate that NTHI express PilA in vivo, and that PilA plays an important role in the pathogenesis of an upper respiratory tract infection induced by NTHI.
The Major Brain Cholesterol Metabolite 24(S)-Hydroxycholesterol Is a Potent Allosteric Modulator of<i>N</i>-Methyl-d-Aspartate Receptors (2013)

N-methyl-D-aspartate receptors (NMDARs) are glutamate-gated ion channels that are critical to the regulation of excitatory synaptic function in the CNS. NMDARs govern experience-dependent synaptic plasticity and have been implicated in the pathophysiology of various neuropsychiatric disorders including the cognitive deficits of schizophrenia and certain forms of autism. Certain neurosteroids modulate NMDARs experimentally but their low potency, poor selectivity, and very low brain concentrations make them poor candidates as endogenous ligands or therapeutic agents. Here we show that the major brain-derived cholesterol metabolite 24(S)-hydroxycholesterol (24(S)-HC) is a very potent, direct, and selective positive allosteric modulator of NMDARs with a mechanism that does not overlap that of other allosteric modulators. At submicromolar concentrations 24(S)-HC potentiates NMDAR-mediated EPSCs in rat hippocampal neurons but fails to affect AMPAR or GABAA receptors (GABA(A)Rs)-mediated responses. Cholesterol itself and other naturally occurring oxysterols present in brain do not modulate NMDARs at concentrations ≤10 μM. In hippocampal slices, 24(S)-HC enhances the ability of subthreshold stimuli to induce long-term potentiation (LTP). 24(S)-HC also reverses hippocampal LTP deficits induced by the NMDAR channel blocker ketamine. Finally, we show that synthetic drug-like derivatives of 24(S)-HC, which potently enhance NMDAR-mediated EPSCs and LTP, restore behavioral and cognitive deficits in rodents treated with NMDAR channel blockers. Thus, 24(S)-HC may function as an endogenous modulator of NMDARs acting at a novel oxysterol modulatory site that also represents a target for therapeutic drug development.
CO<sub>2</sub>/CH<sub>4</sub> Separation in Ion-Exchanged Zeolite-like Metal Organic Frameworks with Sodalite Topology (<i>sod</i>-ZMOFs) (2013)

In this study, the CO2/CH4 separation performance of zeolite-like metal organic frameworks (ZMOFs) with sodalite (sod) topology was evaluated via molecular simulation methods. Monte Carlo and molecular dynamic simulations were performed to estimate adsorption and diffusion selectivities both before and after the ion exchange of sod-ZMOFs with Li+, Na+, and K+ ions. For this purpose, sod-ZMOF structures that are partially or completely ion-exchanged were constructed by locating cation sites. Adsorption and diffusion selectivities were evaluated to predict permselectivities. Adsorption simulations showed that CO2 and CH4 adsorption sites in sod-ZMOFs are the same and CO2 adsorption is favored strongly over CH4 adsorption in the case of binary adsorption, due to the electrostatic interactions between the framework and CO2. Evaluation of permselectivities showed that partial-ion exchanging does not enhance the CO2 separation performance of these materials, while complete ion-exchanging increases permselectivities more than 1 order of magnitude, which suggests that these materials have a strong potential to be used as adsorbent or membrane materials in natural gas treatment.
Blood–brain barrier shuttle peptides: an emerging paradigm for brain delivery (2016)

Brain delivery is one of the major challenges in drug development because of the high number of patients suffering from neural diseases and the low efficiency of the treatments available. Although the blood-brain barrier (BBB) prevents most drugs from reaching their targets, molecular vectors - known as BBB shuttles - offer great promise to safely overcome this formidable obstacle. In recent years, peptide shuttles have received growing attention because of their lower cost, reduced immunogenicity, and higher chemical versatility than traditional Trojan horse antibodies and other proteins.
Antimony-based quaternary alloys for high-speed low-power electronic devices (2003)

Heterojunction bipolar transistors using In/sub z/Ga/sub 1-z/Sb for the base and In/sub x/Al/sub 1-x/As/sub y/Sb/sub 1-y/ alloys for the collector and emitter have been explored. Modeling of the DC current-voltage characteristics indicate that current gain in excess of 500 may be obtained. The calculations show that the gain is a function of the base-collector conduction band offset. Molecular beam epitaxy (MBE) procedures for growing suitable alloys with a 6.2 /spl Aring/ lattice constant are under development. Double crystal X-ray diffraction, photoluminescence, Hall effect, and atomic force microscopy have been used to determine the quality of the materials grown. To minimize stress-induced defects, the In/sub x/Al/sub 1-x/As/sub y/Sb/sub 1-y/ alloys were grown on undoped GaSb substrates with an AlSb buffer layer. The photoluminescence data indicate that good quality In/sub x/Al/sub 1-x/As/sub y/Sb/sub 1-y/ (x=0.52 and y=0.3) with a band gap near 1 eV, is obtained using growth temperatures between 350 and 400/spl deg/C. Superior surface morphology is also found for growths in this temperature range. Te has been used to dope In/sub x/Al/sub 1-x/As/sub y/Sb/sub 1-y/ n-type in the 10/sup 17/ cm/sup -3/ range. Good diode characteristics with an ideality factor of 1.1 have been obtained for In/sub x/Al/sub 1-x/As/sub y/Sb/sub 1-y/ p-n junctions grown using Te for the n-type dopant and Be for the p-type.
