Gao, Yang published the artcileRobust and anti-fatigue hydrophobic association hydrogels assisted by titanium dioxide for photocatalytic activity, Recommanded Product: Dodecyl 2-methylacrylate, the main research area is hydrophobic association hydrogel titanium dioxide photocatalytic degradation wastewater treatment.

Currently, robust and functional hydrogels have attracted extensive attention due to their potential applications in wastewater treatment, farmland water conservation and other fields. Herein, a series of hydrophobic association hydrogels assisted by titanium dioxide (TiO2) was fabricated via one-pot in situ photo-induced polymerization TiO2 nanoparticles could act as both photo-initiators and phys. crosslinking points. The TiO2-assisted hydrophobic association hydrogels exhibited a high tensile strength of 306 kPa, superior compression strength of 2.17 MPa and excellent fatigue resistance. Simultaneously, the incorporation of TiO2 endowed the hydrogel with photocatalytic capacity for dye wastewater treatment based on the inherent nature of TiO2. The results indicated that the hydrogels contributed to the degradation of various ionic dyes including methylene blue, rhodamine B and bromophenol blue, and the removal of methylene blue achieved a rate of 96.63%. Significantly, the hydrogel could be repeatedly utilized and the removal rate showed no evident decrease after five cycles, indicating that the hydrogels could be powerful candidates as photocatalysts for dye wastewater treatment.

Zhang, Huimin published the artcileThe effect of the LC mixtures with the different clearing point on temperature dependence of the electro-optical properties of polymer dispersed liquid crystals, Application In Synthesis of 142-90-5, the main research area is polymer dispersed liquid crystal clearing point electro optical property.

Two groups of polymer dispersed liquid crystals (PDLCs) have been studied, results indicated, when the liquid crystals (LCs) and the UV monomers before curing in the preparation had poor miscibility, the PDLCs showed poor electro-optical properties. Then, we obtained a series of LC mixtures based on E8 and B001, the clearing point of which changed from 71.6°C to 142.0°C. The further study on the effect of temperature on the electro-optical properties of PDLCs indicated that PDLCs with high temperature resistance may be obtained by increasing the clearing point of LCs coupled with manipulating other LC parameters.

Fedin, Igor published the artcileEnhanced Emission from Bright Excitons in Asymmetrically Strained Colloidal CdSe/CdxZn1-xSe Quantum Dots, HPLC of Formula: 142-90-5, the main research area is enhanced emission bright excitons asym colloidal CdSe CdZnSe QD; acoustic phonon; bright exciton; colloidal quantum dot; exciton fine structure; nanocrystal; single-photon emitter.

Colloidal CdSe quantum dots (QDs) designed with a high degree of asym. internal strain have recently been shown to host a number of desirable optical properties including subthermal room-temperature line widths, suppressed spectral diffusion, and high photoluminescence (PL) quantum yields. It remains an open question, however, whether they are well-suited for applications requiring emission of identical single photons. Here, we measure the low-temperature PL dynamics and the polarization-resolved fluorescence line narrowing spectra from ensembles of these strained QDs. Our spectroscopy reveals the radiative recombination rates of bright and dark excitons, the relaxation rate between the two, and the energy spectra of the quantized acoustic phonons in the QDs that can contribute to relaxation processes. In comparison to conventional colloidal CdSe/ZnS core/shell QDs, we find that in asym. strained CdSe QDs over six times more light is emitted directly by the bright exciton. These results are therefore encouraging for the prospects of chem. synthesized colloidal QDs as emitters of single indistinguishable photons.

Zhao, Zhen published the artcileA laboratory study of self-healing hydrophobic association gels used as lost circulation material, HPLC of Formula: 142-90-5, the main research area is self healing hydrophobic association gel lost circulation material.

Polymer gels, composed of preformed particle gels and in-situ gels, have generated broad interest in lost circulation control for decades. However, there are some drawbacks to them. The sealing layer formed by preformed particle gels was easily eroded by cyclic drilling fluid. The size of them needs match that of pores or fractures. In-situ gels, forming the expected pill in the correct location is challenging due to short gelation time, poor resident ability, and gel strength. Due to their unique recovery properties after damage, self-healing gels have been extensively researched and applied in the biomedicine field. Their prospect application in oil and gas drilling and development engineering has been investigated. In this article, we used self-healing hydrophobic association gels prepared in our previous paper to study their performance in lost circulation control, which aimed to integrate advantages of preformed particle gels and in-situ gels and abandon their disadvantages. The chem. structure and thermal stability of self-healing hydrophobic association gels were measured by FTIR and TGA, resp., indicating good thermal stability. The swelling experiments at different temperatures suggested that they could absorb more water with the rise of temperature The healing performance of self-healing gel particles at different temperatures and pressures showed that they could heal into a whole gel with good strength at 1-6 MPa and 25-80°C. Their healing properties were prone to temperature, followed by healing time. Their plugging performance was tested by a high temperature and pressure filter, meaning that the breakthrough pressure of 3% self-healing gel plugging agent was 3.5 MPa at 80°C, using a steel model with a fracture width of 1 mm to imitate fracture formation. The microscopic visualization device saw gel particles’ plugging and healing process, indicating that they entered the lost circulation channels, formed a sealing layer like preformed particle gels, and healed into gel pill like in-situ gels. Self-healing gels could provide a new approach to controlling lost circulation and have a promising application prospect.

Gardner, Wil published the artcileToF-SIMS and Machine Learning for Single-Pixel Molecular Discrimination of an Acrylate Polymer Microarray, HPLC of Formula: 142-90-5, the main research area is ToF MS machine learning mol discrimination acrylate polymer microarray.

Combinatorial approaches to materials discovery offer promising potential for the rapid development of novel polymer systems. Polymer microarrays enable the high-throughput comparison of material phys. and chem. properties-such as surface chem. and properties like cell attachment or protein adsorption-in order to identify correlations that can progress materials development. A challenge for this approach is to accurately discriminate between highly similar polymer chemistries or identify heterogeneities within individual polymer spots. Time-of-flight secondary ion mass spectrometry (ToF-SIMS) offers unique potential in this regard, capable of describing the chem. associated with the outermost layer of a sample with high spatial resolution and chem. sensitivity. However, this comes at the cost of generating large scale, complex hyperspectral imaging data sets. We have demonstrated previously that machine learning is a powerful tool for interpreting ToF-SIMS images, describing a method for color-tagging the output of a self-organizing map (SOM). This reduces the entire hyperspectral data set to a single reconstructed color similarity map, in which the spectral similarity between pixels is represented by color similarity in the map. Here, we apply the same methodol. to a ToF-SIMS image of a printed polymer microarray for the first time. We report complete, single-pixel mol. discrimination of the 70 unique homopolymer spots on the array while also identifying intraspot heterogeneities thought to be related to intermixing of the polymer and the pHEMA coating. In this way, we show that the SOM can identify layers of similarity and clusters in the data, both with respect to polymer backbone structures and their individual side groups. Finally, we relate the output of the SOM anal. with fluorescence data from polymer-protein adsorption studies, highlighting how polymer performance can be visualized within the context of the global topol. of the data set.

Zhang, Xiaoyu published the artcileHighly efficient solar evaporator based on a hydrophobic association hydrogel, HPLC of Formula: 142-90-5, the main research area is efficient solar evaporator based hydrophobic association hydrogel.

Recently, concerns over water scarcity are on the rise, leading to growing research interest in advanced water purification methods. Solar water purification, which utilizes sustainable energy to sep. water impurities and water through evaporation, is emerging as a promising strategy for clean water production Here, we report a novel solar evaporator based on a carbon nanotube composite polyacrylamide hydrogel (CAH) with a high solar evaporation rate of 4.3 kg·m-2·h-1 under 1 sun irradiation (1 kW·m-2). Such a highly efficient solar evaporator is achieved by introducing solar absorbers (carboxyl multi-walled carbon nanotubes) in the hydrophilic skeleton (polyacrylamide) of hydrophobic association hydrogel. More importantly, the self-healing properties endowed by hydrophobic association also provide a simple fabrication route of double-layer hydrogel-based solar evaporator. By a proper double-layer structure design, the solar evaporation rate of CAH can be further increased to a record high value of 5.1 kg·m-2·h-1. In addition, the CAH can effectively remove salt ions and heavy metal ions in water. The extraordinary performance along with the simple and low-cost fabrication route of CAH offers possibilities for practical ultra-fast solar water purification under natural sunlight. Our solar evaporator can achieve long-term ultra-fast water purification by using sustainable solar energy as the only energy resource.

Qin, Zhihui published the artcileCarbon nanotubes/hydrophobically associated hydrogels as ultrastretchable, highly sensitive, stable strain, and pressure sensors, Related Products of esters-buliding-blocks, the main research area is carbon nanotube polyacrylamide conductive hydrogel skin like pressure sensor; carbon nanotubes; high strength; hydrophobic association; nanocomposite hydrogel; skin-like sensor.

Conductive hydrogels have become one of the most promising materials for skin-like sensors because of their excellent biocompatibility and mech. flexibility. However, the limited stretchability, low toughness, and fatigue resistance lead to a narrow sensing region and insufficient durability of the hydrogel-based sensors. In this work, an extremely stretchable, highly tough, and anti-fatigue conductive nanocomposite hydrogel is prepared by integrating hydrophobic carbon nanotubes (CNTs) into hydrophobically associated polyacrylamide (HAPAAm) hydrogel. In this conductive hydrogel, amphiphilic sodium dodecyl sulfate was used to ensure uniform dispersion of CNTs in the hydrogel network, and hydrophobic interactions between the hydrogel matrix and the CNT surface formed, greatly improving the mech. properties of the hydrogel. The obtained CNTs/HAPAAm hydrogel showed excellent stretchability (ca. 3000%), toughness (3.42 MJ m-3), and great anti-fatigue property. Moreover, it exhibits both high tensile strain sensitivity in the wide strain ranges (gauge factor = 4.32, up to 1000%) and high linear sensitivity (0.127 kPa-1) in a large-pressure region within 0-50 kPa. The CNTs/HAPAAm hydrogel-based sensors can sensitively and stably detect full-range human activities (e.g., elbow rotation, finger bending, swallowing motion, and pronouncing) and handwriting, demonstrating the CNTs/HAPAAm hydrogel’s potential as the wearable strain and pressure sensors for flexible devices.

Schork, F. Joseph published the artcileMonomer transport in emulsion polymerization III terpolymerization and starved-feed polymerization, Product Details of C16H30O2, the main research area is emulsion polymerization monomer transport Damkohler number.

A simple math. model of the transport of monomer from the monomer droplets to the polymerizing polymer particles during batch emulsion homopolymerization has been developed and published previously. A Damkohler number for monomer transport in emulsion polymerization is proposed as the ratio of the maximum rate of polymerization divided by the maximum rate of monomer transport out of the monomer droplets. This Damkohler number is calculated from literature values for a number of common monomers. Following standard practice for the use of such a Damkohler number in other reaction-with-transport systems, monomers with a Damkohler number above 0.1 are considered to be transport limited. In a third paper the anal. is extended to batch binary copolymerization Here the anal. is extended to the more industrially relevant cases of batch terpolymn., starved-feed copolymerization, and the combination of the two (starved-feed terpolymn.).
