Yuan, Chuan published the artcileEffect of cosolvent and addition of catalyst (HZSM-5) on hydrothermal liquefaction of macroalgae, Synthetic Route of 41114-00-5, the main research area is macroalgae HZSM catalyst hydrothermal liquefaction cosolvent effect.

Summary : The present study aimed to evaluate the effect of the direct liquefaction of macroalgae in an autoclave reactor (50 mL) possessing water and ethanol as cosolvent. The reaction conditions such as duration, temperature, algae/solvent ratio, the composition of cosolvent (ethanol-water) on product distribution, and bio-oil characterization were studied. The optimum conditions such as 300°C of temperature, 45 min of reaction time, 75% of ethanol, and algae to solvent ratio of 4/40 g/mL supported the bio-oil yield of 46.75% with a conversion rate of 95.5%. The composition and concentration of the compounds in the bio-oil produced under various doses of catalyst were described using GC-MS. The bio-oil characterization showed that the esters were most predominant in hydrothermal liquefaction with a catalyst (HZSM-5) compared with hydrothermal liquefaction in the absence of the catalyst.

Zhang, Shuaifeng published the artcileFluorescence enhancement of quantum dots from the titanium dioxide/liquid crystals/polymer composite films, Application In Synthesis of 142-90-5, the main research area is quantum dot titania liquid crystal polymer composite film fluorescence.

The fluorescence enhancement of QDs-doped TiO2/polymer, LCs/polymer, and TiO2/LCs/polymer composite systems was comparatively studied. It was proposed that the large photoluminescence enhancement of QDs was induced by the synergistic effect of LCs/polymer composite and TiO2 nanoparticles possessing 150 nm particle size and 0.1 wt% loading content. The enhancement factor of QDs-doped TiO2/LCs/polymer nanocomposite film was approx. 6-fold relative to the QDs-doped polymer. Moreover, this nanocomposite film enabled to realize elec. tuning of photoluminescence intensity and be prepared by a facile UV polymerization and large-scale manner. Furthermore, the excellent mech. properties nearly remained unchanged doping 0.1 wt% TiO2 in this LCs/polymer composite.

Zhou, Le published the artcileSwitchable anti-peeping film for liquid crystal displays from polymer dispersed liquid crystals, Related Products of esters-buliding-blocks, the main research area is antipeeping film polymer dispersed liquid crystal.

Liquid crystals displays (LCDs) currently dominate the display market, wherein a wide viewing angle is considered as one of the most important characteristics. However, for LCDs with wide viewing angles, some private information inevitably becomes more visible; thus, an LCD with a switchable viewing angle has attracted greater interest. Here, we report a novel switchable viewing angle film that can make the viewing angle of an LCD elec. switchable between ±30° and ±60°, i.e. between an anti-peeping mode and a share mode, by 5.0 V is turned on and off, resp. The response time necessary to change between the modes is in milliseconds. It is believed that it has potential applications in LCDs with high quality.

Yuan, Mingxia published the artcileMethylcyclohexyl methacrylate-methacrylate copolymers: an effective cold flow improver for the biodiesel blends, Recommanded Product: Dodecyl 2-methylacrylate, the main research area is biodiesel blend methylcyclohexyl methacrylate copolymer cold flow improver.

The poor cold flow property is one of the main obstacle factors in affecting the utilization of high proportion biodiesel blends in engines. In this study, methylcyclohexyl methacrylate-methacrylate copolymers (MCHMA-R1MC, R1 = C12, C14, C16, C18) were synthesized at various molar ratios by radical polymerization, and their structures were analyzed and characterized by FTIR, GPC, and 1H NMR. These resulting copolymers were used as the cold flow improvers for biodiesel/diesel blends in terms of cold filter plugging point (CFPP) and solid point (SP) measurement. Results showed that the CFPP and SP of B20 decreased to a varied extent after MCHMA-R1MC treatment. When the monomer ratio of was 1:7, MCHMA-C14MC (1:7) exhibited the greatest reduction on the CFPP and SP of B20 by 18 °C and 25 °C at 2000 ppm dosage. The effects of MCHMA-R1MC copolymers on crystallization behavior and morphol. were studied through polarizing optical microscope, differential scanning calorimetry and viscosity-temperature curves. The results indicated that MCHMA-C14MC could effectively delay the aggregation of wax crystals and change their crystalline behavior by changing the crystal shapes and inhibiting the formation of large wax crystals and then lower the low-temperature viscosity of biodiesel blends; therefore, MCHMA-C14MC has proven to be a high-effective cold flow improver for the biodiesel blends.

Sun, Bin published the artcileSynthesis and evaluation of alkyl methacrylate-norbornene anhydride copolymers with various pendants as pour point depressants for soybean biodiesel-diesel blends, SDS of cas: 142-90-5, the main research area is alkyl methacrylate norbornene copolymer biodiesel diesel pour point depressant.

Adding more biodiesel in petrochem. diesel is one of the effective methods to alleviate the global petrochem. energy shortage, but the high-proportional biodiesel-diesel blends are always limited by the poor cold flow properties. To address this issue, a series of alkyl methacrylate-norbornene anhydride copolymers (CnMC-NA, n = 12, 14, 16, 18) with different molar ratios were synthesized as pour point depressants for B30 (30 vol% biodiesel + 70 vol% diesel). Results showed that C14MC-NA (6:1) presented the best depressive effects at 0.2 wt% dosage, and the cloud point (CP), cold filter plugging point (CFPP) and pour point (PP) of B30 have reduced by 3, 9 and 10 °C, resp. To further improve their depressive efficiency, nine kinds of alcs. were optimized and grafted modification with C14MC-NA (6:1). The effect of these alcoholysis modified copolymers on CP, CFPP and PP of B30 were systematic researched. Results indicated that long-chain alcs. modified C14MC-NA exhibited better depressive effects on B30 than that of aromatic alcs. and short-chain alcs. Among that, C14MC-NA-C14at 0.15 wt% dosage exhibited the best reduction on CP, CFPP and PP of B30 by 5, 12 and 15 °C, resp. Addnl., the mechanism was discussed by polarizing optical microscopy, rheol. anal., differential scanning calorimeter and low-temperature x-ray diffractometer.

Pi, Menghan published the artcileSustainable MXene/PDA hydrogel with core-shell structure tailored for highly efficient solar evaporation and long-term desalination, Safety of Dodecyl 2-methylacrylate, the main research area is MXene core shell structure solar evaporation desalination.

Solar evaporation is an effective means to solve the scarce of fresh water resources. The developed solar evaporator has the disadvantages of low evaporation rate, poor mech. performance, difficulty in long-term evaporation, and insufficient water purification capacity. Herein, we have developed a core-shell structure hydrogel solar evaporator taking MXene/PDA as the photothermal material. The hydrogel matrix possesses self-healing and remoldability, which is sustainable and in line with the theme of current material development. The prepared core-shell structure hydrogel showed excellent properties, with a compressive stress of 0.4 MPa and the evaporation rate is as high as 3.02 kg m-2 h-1, and the evaporation efficiency is 94.7% under 1 sun illumination, which is better than most of the previously reported solar evaporators. Through the durability experiment in simulated seawater, the long-term desalination ability was verified. Simultaneously, the solar evaporator also exhibits various functions such as dye resistance, and heavy metal ion resistance. The core-shell structure solar evaporator shows great potential in long-term seawater desalination and water purification Furthermore, it provides a promising strategy for the structural design of solar evaporators in the future.

Ding, Tongtong published the artcileA Cu2O-based marine antifouling coating with controlled release of copper ion mediated by amphiphilic PLMA-b-PDMAEMA copolymers, Quality Control of 142-90-5, the main research area is PLMA PDMAEMA amphiphilic copolymer copper oxide marine antifouling coating.

To achieve prolonged and sustainable release of copper ion in Cu2O-containing marine coatings, poly(lauryl methacrylate)-b-poly(2-(N,N-dimethylamino)ethyl methacrylate) (PLMA-b-PDMAEMA) diblock copolymers with different block ratios and mol. weights were synthesized by atom-transfer radical polymerization (ATRP) method. It was proved that the copolymers are able to coordinate with copper ion. And the surface wettability tests showed that the amphiphilic copolymers may undergo structure change in seawater. Taking advantage of the structure transformation and copper coordination abilities, the copolymer was employed to encapsulate Cu2O for the preparation of antifouling coatings. A controllable and continuous release of copper ion from Cu2O/copolymer coatings was then obtained. More importantly, it showed that higher PLMA/PDMAEMA block ratio exhibited better bactericidal rate. Actually, the bactericidal ability of the coating depends on the time duration of copper ion on the surface instead of the hydrolysis speed of the coating, in other words, the hydrophobic interaction of PLMA with the resin may play a major role in the antifouling performance of the marine coating. Self-polishing coatings Cu2O/copolymer/polycaprolactone (PCL) were then prepared and applied for marine field test, the antifouling performances were proved to be comparable to that of the com. available self-polishing coatings.

Martin, Chantal published the artcileSelectively Tunable Luminescence of Perovskite Nanocrystals Embedded in Polymer Matrix Allows Direct Laser Patterning, Quality Control of 142-90-5, the main research area is luminescence perovskite nanocrystal polymer matrix laser patterning.

Cesium lead halide perovskite nanocrystals (NCs) have gained enormous attention as promising light-emitting and light-converting materials. Most of their applications require embedding NCs in various matrixes, which is a challenging task due to their low stability, especially in the case of red-emitting CsPbI3 NCs. In this work, a new approach is proposed allowing the formation of red-emitting perovskite NCs by anion exchange induced directly inside a solid polymer matrix using green-emitting CsPbBr3 NCs as templates and iodododecane as an iodine source. Moreover, a simple and efficient route to photo-assisted termination of the anion exchange reaction in the polymer composite after reaching desired optical properties is demonstrated. The findings allow the authors to pattern a thin composite film with an ultrashort UV laser resulting in a selective generation of green- and red-emitting features with a 15μm resolution
