Doped Lithium Orthosilicates - Promising High Rate Lithium-Ion Conductors for Li-S Batteries (2016)

There is an increased demand for portable energy storage systems that demonstrate high efficiency. The current Li – ion battery system based on Li – graphite insertion chemistry has a theoretical capacity of 372 mAh/g. For Li – ion batteries to be implemented in portable energy devices, specific capacities twice than that of the current system is necessary. Sulfur demonstrates a high theoretical specific capacity of 1672 mAh/g 1 , 2 , and is hence a promising candidate for high energy density lithium batteries. Moreover, sulfur is a low cost material and is easily available. Sulfur has very low conductivity (- 10 -15 S/cm) which restricts the complete utilization of active material. Sulfur forms non – intercalation based polysulfide intermediates (Li 2 S n ; n = 2 – 8) 3 which are soluble in liquid electrolyte resulting in loss of active material. In addition, the dissolved polysulfide gets coated onto the anode resulting in gradual cell voltage drop ultimately resulting in failure. These problems prevent the technology from being commercialized. Jampani et al. demonstrated reduced polysulfide dissolution and improved cycling stability by coating the sulfur cathodes with a lithium-ion conductor (LIC) 4 . The study identified Li 4 SiO 4 as a stable LIC. However, the application of this coating strategy is limited by the ionic conductivity of the LIC. In this work, the Li 4 SiO 4 LIC was doped with dopants identified using first principles calculations by a high temperature solid state approach. The LIC was doped up to 5% without phase separation as represented in Figure 1 . The doped LIC demonstrates a threefold increase in ionic conductivity as shown in Figure 2 . This enhanced ionic conductivity is expected to improve the cycling stability of lithium-sulfur cathodes which will be discussed and presented in detail. References 1. J. R. Akridge, Y. V.

Potential sites of CFTR activation by tyrosine kinases (2020)

The CFTR chloride channel is tightly regulated by phosphorylation at multiple serine residues. Recently it has been proposed that its activity is also regulated by tyrosine kinases, however the tyrosine phosphorylation sites remain to be identified. In this study we examined 2 candidate tyrosine residues near the boundary between the first nucleotide binding domain and the R domain, a region which is important for channel function but devoid of PKA consensus sequences. Mutating tyrosines at positions 625 and 627 dramatically reduced responses to Src or Pyk2 without altering the activation by PKA, suggesting they may contribute to CFTR regulation.
Printed Capacitive Pressure Sensor with Enhanced Sensitivity through a Layered PDMS/BaTiO3 Structure (2021)

Printable electronics have demonstrated significant promise in enabling soft tactile sensing systems. This paper presents a fully printed and soft capacitive pressure sensor realized through a two-dimensional interdigitated capacitor. The sensor transduces applied pressures through a fringing electric field interacting with a deformable elastomer. The deformable elastomer consists of either pure polydimethylsiloxane (PDMS) or a layered PDMS/BaTiO3 structure. A 10 mm overlaid layered structure is created by depositing six alternating layers of a Barium Titanate-PDMS mixture and pure PDMS, followed by a 4 mm PDMS layer on the printed electrode. Multiple tests using standardized pressure and capacitance measurements have been performed to measure and compare the sensitivity between pure PDMS and PDMS/BaTiO3 layered configuration. The capacitive response shows that the layered PDMS/BaTiO3 device enhances the sensitivity for pressures less than 1 kPa by approximately 10x. This work demonstrates the potential of a printed electronic sensor in measuring small-scale pressure variation using inexpensive and simple fabrication methods.
Summary of the ISEV workshop on extracellular vesicles as disease biomarkers, held in Birmingham, UK, during December 2017 (2019)

This report summarises the presentations and activities of the ISEV Workshop on extracellular vesicle biomarkers held in Birmingham, UK during December 2017. Among the key messages was broad agreement about the importance of biospecimen science. Much greater attention needs to be paid towards the provenance of collected samples. The workshop also highlighted clear gaps in our knowledge about pre-analytical factors that alter extracellular vesicles (EVs). The future utility of certified standards for credentialing of instruments and software, to analyse EV and for tracking the influence of isolation steps on the structure and content of EVs were also discussed. Several example studies were presented, demonstrating the potential utility for EVs in disease diagnosis, prognosis, longitudinal serial testing and stratification of patients. The conclusion of the workshop was that more effort focused on pre-analytical issues and benchmarking of isolation methods is needed to strengthen collaborations and advance more effective biomarkers.
Revealing a Mode Interplay That Controls Second-Harmonic\nRadiation in Gold Nanoantennas (2017)

In this work, we investigate the generation of second harmonic light by gold\nnanorods and demonstrate that the collected nonlinear intensity depends upon a\nphase interplay between different modes available in the nanostructure. By\nrecording the backward and forward emitted second harmonic signals from\nnanorods with various lengths, we find that the maximum nonlinear signal\nemitted in the forward and backward directions is not obtained for the same\nnanorod length. We confirm the experimental results with the help of full-wave\ncomputations done with a surface integral equation method. These observations\nare explained by the multipolar nature of the second harmonic emission, which\nemphasizes the role played by the relative phase between the second harmonic\nmodes. Our findings are of a particular importance for the design of plasmonic\nnanostructures with controllable nonlinear emission and nonlinear plasmonic\nsensors as well as for the coherent control of harmonic generations in\nplasmonic nanostructures.\n

Effect of Salt Reduction on Dough Handling and the Breadmaking Quality of Canadian Western Red Spring Wheat Varieties (2017)

The effect of salt (NaCl) on the breadmaking quality of 37 varieties of Canadian Western Red Spring wheat ( Triticum aestivum L.) was investigated along with dough stickiness for a 20 variety subset. A principal components analysis indicated that dough development time (DDT), mixing tolerance index (MTI), and stability (STA) were highly correlated. DDT showed an inverse relationship with MTI ( r = –0.73) and a positive relationship with STA ( r = 0.89). STA was also negatively related to MTI ( r = –0.76). A reduction of salt from 2.0 to 1.1% (based on flour weight) was considered from a practical perspective. Each variety responded differently to salt reduction. Obtaining an optimal dough consistency with less salt required less work input and shorter mixing time. Overall, decreasing loaf volume with reducing salt content was observed, although certain varieties produced the opposite effect. This suggests that for a particular flour, depending on the inherent flour strength, there is a level of NaCl that produces an optimum between gluten strength and gas‐holding capacity of the dough, resulting in a loaf with good crumb texture and an even distribution of bubble sizes. A stickiness test was performed on selected varieties to evaluate the dough handling properties at 1.1 and 2.0% salt levels. The overall trend showed an increase in stickiness with a decrease in the salt content; however, certain varieties showed no change.
Structure of strontium hydroxide octahydrate, Sr(OH)2·8H2O, at 20, 100 and 200 K from neutron diffraction (2005)

The crystal structure of Sr(OH)2*8H2O has been determined at 20, 100 and 200 K from neutron diffraction data. The structure consists of double layers of H2O and OH- ions separated by Sr2+ along the c axis. The Sr2+ ions are eight-coordinated by water O atoms in a square antiprism configuration. Each H2O molecule is engaged in three hydrogen bonds. The OH- ions form chains of acceptor and donor bonds along the fourfold axis with O atoms engaged in four bonds with H2O molecules, such that both non-equivalent O atoms have square-pyramidal environments of five H atoms and the overall bonding configurations of distorted octahedra.

Gasification Kinetics in Continuous Supercritical Water Reactors (2020)

Supercritical water gasification (SCWG) is an emerging technology with synergistic applications in renewable energy and waste processing. Supercritical water (SCW) functions as a green reaction medium during the gasification process, serving to dissolve and decompose complex organic molecules via ionic, radical, hydrolysis, and pyrolysis reaction mechanisms. Researchers investigate the decomposition of model compounds in order to predict product yields and conversion efficiencies during the gasification of heterogeneous biomass waste, food waste, sewage sludge, and other available feedstocks. Continuous, laboratory-scale reactors are often employed to study reaction kinetics, pathways, and mechanisms. This chapter synthesizes previous work investigating model compound gasification in continuous supercritical water reactors (SCWRs). A summary of continuous reactor design strategies is presented for practical benefit, followed by a discussion on reaction chemistry in the supercritical water environment. Reaction pathways and mechanisms have been investigated for several model compounds, lending insight toward the conditions needed for the complete conversion of real-world feedstocks. Several studies assume first-order reaction kinetics and propose Arrhenius parameters for the decomposition reaction. The first-order rate assumption must be carefully evaluated, and the applicable temperature range must be specified. Opportunities for further research are discussed.
Synthesis and Biological Evaluation of 1,2,3-Triazole Tethered Thymol-1,3,4-Oxadiazole Derivatives as Anticancer and Antimicrobial Agents (2021)

A library of 1,2,3-triazole-incorporated thymol-1,3,4-oxadiazole derivatives (<b>6</b>-<b>18</b>) hasbeen synthesized and tested for anticancer and antimicrobial activities. Compounds <b>7</b>, <b>8</b>, <b>9</b>, <b>10</b>, and <b>11</b> exhibited significant antiproliferative activity. Among these active derivatives, compound 2-(4-((5-((2-isopropyl-5-methylphenoxy)methyl)-1,3,4-oxadiazol-2-ylthio)methyl)-1<i>H</i>-1,2,3-triazol-1-yl)phenol (<b>9</b>) was the best compound against all three tested cell lines, MCF-7 (IC<sub>50</sub> 1.1 μM), HCT-116 (IC<sub>50</sub> 2.6 μM), and HepG2 (IC<sub>50</sub> 1.4 μM). Compound <b>9</b> was found to be better than the standard drugs, doxorubicin and 5-fluorouracil. These compounds showed anticancer activity through thymidylate synthase inhibition as they displayed significant TS inhibitory activity with IC<sub>50</sub> in the range 1.95-4.24 μM, whereas the standard drug, Pemetrexed, showed IC<sub>50</sub> 7.26 μM. The antimicrobial results showed that some of the compounds (<b>6</b>, <b>7</b>, <b>9</b>, <b>16</b>, and <b>17</b>) exhibited good inhibition on <i>Escherichia coli</i> (<i>E. coli</i>) and <i>Staphylococcus aureus</i> (<i>S. aureus</i>). The molecular docking and simulation studies supported the anticancer and antimicrobial data. It can be concluded that the synthesized 1,2,3-triazole tethered thymol-1,3,4-oxadiazole conjugates have both antiproliferative and antimicrobial potential.
Sampling Cone (2016)

This document contains recommendations for terminology in mass spectrometry. Development of standard terms dates back to 1974 when the IUPAC Commission on Analytical Nomenclature issued recommendations on mass spectrometry terms and definitions. In 1978, the IUPAC Commission on Molecular Structure and Spectroscopy updated and extended the recommendations and made further recommendations regarding symbols, acronyms, and abbreviations. The IUPAC Physical Chemistry Division Commission on Molecular Structure and Spectroscopy’s Subcommittee on Mass Spectroscopy revised the recommended terms in 1991 and appended terms relating to vacuum technology. Some additional terms related to tandem mass spectrometry were added in 1993 and accelerator mass spectrometry in 1994. Owing to the rapid expansion of the field in the intervening years, particularly in mass spectrometry of biomolecules, a further revision of the recommendations has become necessary. This document contains a comprehensive revision of mass spectrometry terminology that represents the current consensus of the mass spectrometry community.

Integration of fractal biosensor in a digital microfluidic platform (2015)

Fractal capacitive electrodes have been successfully integrated into a digital microfluidic open-platform. These electrodes perform actuation and withstand voltages up to 300V without insulation-layer breakdown. They were used to quantify the concentration levels of C-reactive protein (CRP) to determine the risk of cardiovascular disease. The capacitance increased sevenfold and stabilized in less than 5 minutes. The sensor shows a decreasing trend of capacitance readouts with the increase of concentrations. The same immunoassay was tested with untreated electrodes and showed no significant response, which suggests that immobilization was necessary. This configuration allows the electrodes to be used as biosensors.
Weibull analysis of the kinetics of resistive switches based on tantalum oxide thin films (2013)

We study the kinetics of bipolar resistive switches in tantalum oxide thin films having different thicknesses. The time to switch from the high resistance state to the low resistance state (SET) is measured repeatedly in a single cell of each sample and analyzed based on a Weibull distribution. In the thin film device the Weibull parameter fJ> 1 is observed in the short time region, followed by a distribution with ß <; 1 in the long time region. This indicates that a progressing phenomenon induces the SET action in the short time region, while it is saturated in the long time region, where the SET is triggered by a sporadic event. In the thick film sample a distribution with ß<; 1 is dominant almost in the whole time range. Further analysis revealed that the heat generated before the switch-on can be responsible for the SET in the fJ> 1 mode.
Monitoring of Target-Site Mutations Conferring Insecticide Resistance in Spodoptera frugiperda (2020)

Fall armyworm (FAW), <i>Spodoptera frugiperda</i>, a major pest of corn and native to the Americas, recently invaded (sub)tropical regions worldwide. The intensive use of insecticides and the high adoption of crops expressing <i>Bacillus thuringiensis</i> (Bt) proteins has led to many cases of resistance. Target-site mutations are among the main mechanisms of resistance and monitoring their frequency is of great value for insecticide resistance management. Pyrosequencing and PCR-based allelic discrimination assays were developed and used to genotype target-site resistance alleles in 34 FAW populations from different continents. The diagnostic methods revealed a high frequency of mutations in acetylcholinesterase, conferring resistance to organophosphates and carbamates. In voltage-gated sodium channels targeted by pyrethroids, only one population from Indonesia showed a mutation. No mutations were detected in the ryanodine receptor, suggesting susceptibility to diamides. Indels in the ATP-binding cassette transporter C2 associated with Bt-resistance were observed in samples collected in Puerto Rico and Brazil. Additionally, we analyzed all samples for the presence of markers associated with two sympatric FAW host plant strains. The molecular methods established show robust results in FAW samples collected across a broad geographical range and can be used to support decisions for sustainable FAW control and applied resistance management.
Computed SAR and thermal elevation in a 0.25-mm 2-D model of the human eye and head in response to an implanted retinal stimulator. II. Results (2003)

This is the second of a series of two papers on the thermal increase in the human eye and head in response to an implanted retinal stimulator. This paper provides specific absorption rates induced in the human head by the extraocular unit and the temperature increases associated with induced electromagnetic fields and power dissipation of the implanted microchip. Results are provided for different assumptions about choroid blood flow. It is shown that computed results associated with the power dissipation of the implanted microchip, corresponding to temperature increases of approximately 0.6/spl deg/C in the midvitreous of the eye and 0.2/spl deg/C in the retina, closely parallel in-vivo experimental results in animals.
Effective time domain analysis of periodic structures (1993)

In the paper we introduce a new approach to the analysis of periodic structures such as corrugated transmission lines or slow wave structures. It is based on the time domain simulation (FD-TD or TLM) of only one period, with a special type of boundary conditions modelling its behaviour in the entire structure. Two versions of the new method are considered. The first one utilizes complex notation in the phase constant domain while the other one reduces calculations to real numbers. We show how the new approach has been applied to several practical cases producing excellent results.
