Electric Literature of C21H14Br4O5S. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene.

Author is Ishii, Yuya; Sanemoto, Keiji; Iumsrivun, Chonthicha.

In this study, multi-sensing dye-doped electrospun polystyrene microfiber mats were developed. The individual fibers are composed of an inexpensive atactic polystyrene; aPS doped with a gas-sensitive dye (bromocresol green), BCG. The fiber mats exhibited outstanding quasi-static direct electromech. properties, which were enhanced by increasing the doping ratio of BCG. This improvement was attributed to an increase in the real charge d. stored in the fiber mats and a decrease in their secant modulus of elasticity. The increase in charge d. with increasing BCG doping ratios was attributed to the enhanced conductivity of the electrospinning solution; the decrease in secant modulus was attributed to the decrease in fiber diameter and d. of the fiber mats. The BCG-doped aPS fiber mats demonstrated distinguishable color changes even under a low concentration of ventilating ammonia gas (1 ppm). Addnl., the degree of color change increased with an increase in ammonia gas concentration The proposed multi-sensing microfiber mats can facilitate the development of wearable, lightweight multi-sensors with flexibility and breathability, which, for example, ensure the safety of workers at risk of exposure to harmful gases.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 3,3-Bis(3,5-dibromo-4-hydroxy-2-methylphenyl)-3H-benzo[c][1,2]oxathiole 1,1-dioxide, is researched, Molecular C21H14Br4O5S, CAS is 76-60-8, about Conformal Coating of Orthopedic Plates with X-ray Scintillators and pH Indicators for X-ray Excited Luminescence Chemical Imaging through Tissue.Product Details of 76-60-8.

We describe a pH-indicating material that can be directly implanted or coated on orthopedic implant surfaces to provide high-spatial-resolution pH mapping through tissue by X-ray excited luminescence chem. imaging (XELCI). This is especially useful for detecting local pH changes during treatment of implant-associated infections. The material has two layers: an X-ray scintillator layer with Gd2O2S:Eu in epoxy, which emits 620 and 700 nm light when irradiated with X-rays, and a pH indicator dye layer, which absorbs some of the 620 nm light in a pH-dependent fashion. To acquire each pixel in the image, a focused X-ray beam irradiates a small region of scintillators and the ratio of 620 to 700 nm light is acquired through the tissue. Scanning the X-ray beam across the implant surface generates high-spatial-resolution chem. measurements. Two associated challenges are (1) to make robust sensors that can be implanted in tissue to measure local chem. concentrations specifically for metal orthopedic implants and (2) to conformally coat the implant surface with scintillators and pH indicator dyes in order to make measurements over a large area. Previously, we have phys. pressed or glued a pH-sensitive hydrogel sensor onto the surface of an implant, but this is impractical for imaging over large irregular device areas such as an orthopedic plate with holes and edges. Herein, we describe a chem. sensitive and biocompatible XELCI sensor material that can conformally coat the implant surface. A two-part com.-grade epoxy resin was mixed with Gd2O2S:Eu and adhered to the titanium surface. Sugar and salt particles were added to the surface of the epoxy as it cured to create a roughened surface and increase the surface area. On this roughened surface, a secondary layer of diacrylated polyethylene glycol (PEG) hydrogel, containing a pH sensitive dye, was polymerized This combination of epoxy-PEG layers was found to adhere well to the metal implant unlike other previously tested polymer surfaces, which delaminated when exposed to water or humidity. The focused X-ray beam enabled 0.5 mm spatial resolution through 1 cm-thick tissue. The pH sensor-coated orthopedic plate was imaged with XELCI, through tissue, with different pH levels to acquire a calibration curve. The plates were also imaged through tissue, with a low pH region on one section due to growth of a Staphylococcus aureus biofilm. A pH sensor-coated stainless-steel rod with two distinct pH regions was inserted in a rabbit tibia specimen, and the pH was imaged through both bone and soft tissue. These studies demonstrate the use of pH sensor-coated orthopedic plates and rods for mapping the local pH through tissue during biofilm formation by XELCI.

The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 3,3-Bis(3,5-dibromo-4-hydroxy-2-methylphenyl)-3H-benzo[c][1,2]oxathiole 1,1-dioxide, is researched, Molecular C21H14Br4O5S, CAS is 76-60-8, about Fabrication of a “”progress bar”” colorimetric strip sensor array by dye-mixing method as a potential food freshness indicator. Author is Wang, Guannan; Huang, Shaoyun; He, Hui; Cheng, Jiawei; Zhang, Tao; Fu, Zhiqiang; Zhang, Shasha; Zhou, Yuzhi; Li, Houbin; Liu, Xinghai.

Colorimetric sensing is a low-cost, intuitive method for monitoring the freshness of food. We prepared a colorimetric strip sensor array by mixing different amounts of bromophenol blue (BPB) and bromocresol green (BCG). As results of NH3 simulation, the array strip turned from yellow to blue, and the number of blue spots increased with the increasing NH3, like a progress bar. Although the actual color is quite different, the color-changing trend was consistent with the simulated model calculated by a computer. The progress bar results remained stable under three lighting conditions. Furthermore, in the Cod preservation experiment, the color-changing progress of the strip sensor array is consistent with the simulation and can indicate Cod freshness while providing more distinguish levels. Therefore, a “”progress bar”” indicator built by this strategy possess the potential of realizing nondestructive, more accurate, and com. available food quality monitoring through the naked eye and smart equipment recognition.

This work describes photocatalytic application of γ-alumina (γ-Al2O3) surface-anchored palladium and palladium oxide nanoparticles (Pd-γ-Al2O3 and PdO-γ-Al2O3NPs) synthesized by a novel co-precipitation technique. The palladium(0) NPs (Pd-γ-Al2O3) were formed by calcination of the sample in inert medium, whereas PdO NPs (PdO-γ-Al2O3) were obtained by calcination of the sample in atm. oxygen. As-synthesized Pd-γ-Al2O3 and PdO-γ-Al2O3 NPs are characterized by X-ray diffraction, Fourier transform-IR spectroscopy, field emission SEM and photoluminescence (PL) spectra. The PL spectra of Pd-γ-Al2O3 and PdO-γ-Al2O3 NPs display visible-light emissions from 450 to 500 nm at room temperature This work aims to study the photocatalytic degradation of organic dye pollutants, including bromocresol green (BCG), bromothymol blue, methylene blue and methyl orange using Pd-γ-Al2O3 and PdO-γ-Al2O3 NPs as potential photocatalysts. Exptl. parameters, including the admitting concentration of the organic dye solution, Pd-γ-Al2O3 and PdO-γ-Al2O3 photocatalyst dosage, and pH, were varied to ascertain favorable conditions for photocatalytic degradation The results indicate that the organic dye BCG is completely (100%) degraded in aqueous solution under UV light, compared with the other organic dyes. Furthermore, Pd-γ-Al2O3 NPs showed better photocatalytic performance than PdO-γ-Al2O3 NPs. The possible photocatalytic degradation mechanism of the organic dyes by Pd-γ-Al2O3 and PdO-γ-Al2O3 photocatalysts is proposed. The studies reveal that Pd and PdO NPs anchored on the γ-Al2O3 surface are promising and effective catalysts for photocatalytic degradation of organic dyes.

The article 《Morphology effect on zinc oxide quantum photoinitiators for radical polymerization》 in relation to this compound, is published in Nanoscale. Let’s take a look at the latest research on this compound (cas:76-60-8).

Semiconductor nanocrystal based photoinitiators, quantum PIs, are a viable alternative to organic photoinitiators demonstrating unique advantages, including a broad and tunable excitation window, limited migration, and more. Aiming towards efficient quantum PIs with tunable properties, a deeper understanding of the relationships between the nanoparticle properties and their efficiency is required. Herein, we studied the morphol. effect on ZnO nanocrystals functioning as photoinitiators in both water-based and solvent-free formulations by comparing rod and pyramidal shaped particles of similar volumes and nearly identical surface area. Superior polymerization performances are measured for the nanorods. Photocatalytic characterization including oxygen consumption and reactive oxygen species formation as well as dyes reduction and oxidation, also showed enhanced activities for the nanorods. The different performances were attributed to the anisotropic nanorod morphol. which is beneficial for charge separation as well as to the presence of a reactive [0001] facet in the nanorods, which is known to increase the adsorption of mol. oxygen and anionic mols., thus affecting the catalytic activity. These observations, along with the higher photoinitiation efficiency of the ZnO nanorods, bring them closer to functionality as photoinitiators in numerous photopolymerization applications.

BiOBr is a kind of promising photocatalyst because of excellent photoelec. separation efficiency and chem. stability. In order to improving practical application performance, a novel BiOBr ultra-thin nano-roundel (BiOBr-nR) was constructed in water-in-oil (WIO) emulsion microspheres, and prepared by hydrothermal reaction. Its sp. surface area was increased by changing microtopog. and downsizing. After being characterized by FT-IR, XPS, powder X-ray diffraction (XRD), scanning electron microscope (SEM), Brunauer-Emmett-Teller (BET), UV-Vis diffuse reflectance spectra (UV-Vis DRS) and photoluminescence (PL), it indicated the BiOBr-nR, being doped by C and N, is 4-5 times smaller and thinner than that of conventional BiOBr. It was also found that BiOBr-nR has narrower band gap energy (2.78 eV), excellent photocatalytic activity, significant reusability, and stability. The obtained BiOBr-nR photocatalysts were applied to remove organics It presented excellent photocatalytic activity, the degradation rate of organics got to 99.2%. The mechanism of photodegradation was investigated, which indicated superoxide radicals and holes play a major role in the degradation of organics Therefore, BiOBr-nR is a kind of environmentally friendly photocatalyst with stable photocatalytic activity, the removal rate still more than 97% after recycling for 10 times. In summary, we found a novel insight for designing and preparation of efficient and recyclable BiOBr photocatalytic materials, which exhibits high photoresponse for purifying the wastewater.

A combinative approach for chem. anal. makes it possible to distinguish a mixture of a large number of compounds from other mixtures in a single step. This work demonstrates a combinative anal. approach by using surface nanodroplets for integrating nanoextn. and colorimetric reactions for the identification of multi-component mixtures The model analytes are acidic compounds dissolved in oil that are extracted into aqueous droplets on a solid substrate. The proton from acid dissociation reacts with the halochromic chem. compounds inside the droplets, leading to the color change of the droplets. The rate of the colorimetric reaction exhibits certain specificity for the acid type, distinguishing acid mixtures with the same pH value. The underlying principle is that the acid transport rate is associated with the partition coefficient and the dissociation constant of the acid, in addition to the concentration in oil. As a demonstration, we showed that droplet-based combinative anal. can be applied for anti-counterfeiting of various alc. spirits by comparing decolor time of organic acid mixtures in the spirits. The readout can be done by using a common hand-hold mobile phone.

Wearable interfaces are central to multiple healthcare and wellness strategies encompassing diet and nutrition, personalized health monitoring, and performance optimization. Specifically, the advent of flexible electronic formats coupled with microfluidic interfaces resulted in sophisticated conformal devices for biofluid sampling and quantification. Here, a complementary approach is presented to wearable sensing by using a large-scale, conformal, distributed format that relies on the use of biomaterial-based inks to print and stabilize deterministic patterns of biochem. reporters with high resolution Colorimetric devices can vary in size and a sensing T-shirt based on a colorimetric pattern is developed to illustrate the utility that such formats can add to the wearable interface space. Image anal. allows parameter variation to be tracked in real-time, yielding a map-like format of distributed biophys. response.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 76-60-8, is researched, Molecular C21H14Br4O5S, about Removal and recovery of triphenylmethane dyes from wastewater with temperature-sensitive magnetic ionic liquid aqueous two-phase system, the main research direction is temperature sensitive magnetic ionic liquid dye removal wastewater treatment.Recommanded Product: 3,3-Bis(3,5-dibromo-4-hydroxy-2-methylphenyl)-3H-benzo[c][1,2]oxathiole 1,1-dioxide.

In this report, temperature-sensitive magnetic ionic liquids (MILs) were discovered for the first time. Two polypropylene glycol 400 (PPG400) based temperature-sensitive MILs were synthesized, characterized and successfully applied to construct the first reported temperature-sensitive magnetic ionic liquid aqueous two-phase system (MILATPs). To the best of our knowledge, this proposed temperature-sensitive MILATPs combined the advantages of rapid extraction, organic solvent free for the whole process, magnetic separation and thermo-recovery of MIL in a separation process for the first time. Temperature-sensitive MILATPs were successfully applied for the removal and recovery of three triphenylmethane dyes from wastewater. Phase behaviors and several influencing factors on dye extraction efficiency were detailedly investigated and optimized with good performances. Both high purities of MIL and dye could be ideally recovered simply by heating and the recoveries of dyes were higher than 93%. Addnl., the two MILs could be recycled for at least 6 times with steadily high extraction efficiencies. Furthermore, this novel temperature-sensitive MILATPs had been successfully applied for real industrial dyed wastewater treatment with satisfactory recoveries of both MIL and dye. This novelly proposed temperature-sensitive MILATPs is simple and green method which is showing great potential in a separation-recovery process and the industrial treatment of dyed wastewater.

Let’s take a look at the latest research on this compound (cas:76-60-8).

The aim of this study was to compare the Candida bromcresol green (BCG) medium with the chromogenic (CHROM) Brilliance Candida agar and Sabouraud dextrose agar (SDA) media in regard to their capability of detecting Candida isolates from mono- or dual-species cultures. We prepared Candida isolates’ suspensions to obtain mono-species (n = 18) or dual-species (n = 153) culture plates per each medium, and three readers independently observed 513 plates at 24-h, 48-h and 72-h incubation time. We scored reading results as correct, over or under detection compared to the expected species number(s). BCG showed significantly higher correct-detection and lower under-detection rates for all Candida species when observed by at least one reader. At 24-h reading, 12 mono-species cultures had correct (or over) detections in all media, whereas 106, 60 and 78 dual-species cultures had correct (or over) detections in BCG, CHROM or SDA, resp. BCG provides the basis for an accurate laboratory diagnosis of Candida infections.
