Shen, Wenbo; Liu, Jiaoshi; Du, Bin; Zhuo, Haitao; Chen, Shaojun published an article in 2021. The article was titled 《Thermal- and light-responsive programmable shape-memory behavior of liquid crystalline polyurethanes with pendant photosensitive groups》, and you may find the article in Journal of Materials Chemistry A: Materials for Energy and Sustainability.Synthetic Route of C3H7BrO The information in the text is summarized as follows:

In this study, a liquid crystalline polyurethane that exhibits thermal- and light-responsive programmable shape-memory behavior was prepared via the quaternization reaction between a mesogenic azobenzene compound and a conventional polyurethane (PU). In the film, the variation in the configuration of mesogenic azobenzene units afforded the internal stress to actuate the motion of the polymer chains and induced the chains to adopt a coiled conformation, leading to the macroscopic deformation of the film under light stimulation. The hard segments of PU provided the skeleton that froze the conformation of the polymer chains and ensured that the temporary shape was maintained after removing the stimuli. The variation of the tensile stress required for maintaining the elongation of the film under different stimuli was measured, and a possible mechanism for the multiple stimuli-responsive shape deformation of the material from the point of view of the evolution of polymer chain conformations was also discussed. Moreover, flexible photomech. devices based on the liquid crystalline polyurethane film were fabricated, and the soft devices could catch an object even in the absence of stimuli. This work can provide a creative route for the fabrication and practical application of novel photomech. devices and soft robotics more in line with the requirements of energy-saving and intelligence.

《Exploring AIE luminogens as stickers to construct self-healing ionomers and as probes to detect the microscopic healing dynamics》 was written by Gu, Shiyu; Wang, Hao; Zhang, Hao; Peng, Yan; Zhang, Linjun; Zhang, Junqi; Zheng, Jing; Wu, Jinrong. Application In Synthesis of 3-Bromopropan-1-ol And the article was included in Journal of Materials Chemistry A: Materials for Energy and Sustainability in 2021. The article conveys some information:

In spite of considerable progress in self-healing polymers, detecting the healing kinetics and its underlying mol. mechanism is still in the early development stage. Herein, we design a self-healing ionomer by grafting AIEgens (PyTPE) as sticky groups onto a bromo-matrix (PBMB). The ionomer shows good mech. properties (15 MPa, 300%) and crack healing efficiency at room temperature Interestingly, the grafted AIEgen stickers enable us to quantify the healing kinetics and its underlying microscopic structural change through the evolution of fluorescence intensity induced by the AIE effect. In addition, a 2D correlation anal. indicates that the decoupled ionic moieties move first to recombine again during the healing process, finally leading to the reconstruction of a transient network and macro-healing. Therefore, this work offers a fluorescence-based method to study the microscopic self-healing mechanism of ionomers during damage and healing processes.

《Nanocomposites of ionic copolymer integrating Gd-containing polyoxometalate as a multiple platform for enhanced MRI and pH-response chemotherapy》 was written by Zhou, Tingting; Wan, Guofeng; Li, Bao; Wu, Lixin. Synthetic Route of C3H7BrO And the article was included in Journal of Materials Chemistry B: Materials for Biology and Medicine in 2020. The article conveys some information:

This article describes the fabrication of nanosized paramagnetic drug carriers via the assembly of a pH-responsive hydrophilic block copolymer poly(polyethylene glycol Me ether methacrylate)-b-poly(methacrylic acid-co-trimethyl ammonium bromide Pr methacrylate) (PPMT) and polyoxometalate K13[Gd(β2-SiW11O39)2] (GdSiW11) through electrostatic interaction. Owing to the hydrophilicity, large mol. weight, and high content of the GdSiW11 cluster bearing in the nanocomposites, the organic-inorganic nanocomposite exhibited an impressive longitudinal relaxivity as a contrast agent for magnetic resonance imaging (MRI). The surplus neg. charges from the polyoxometalate cluster in the polymer nanocomposites facilitated the capture of the anti-tumor drug doxorubicin (DOX). The DOX-loaded nanocomposites were stable under the physiol. environment, whereas a responsive release of DOX was achieved at pH values similar to the tumor microenvironment due to the regulation of the polyoxometalate and carboxyl groups. The DOX-loaded PPMT2-GdSiW11 nanocomposites were observed to enrich effectively at tumor sites through MRI after i.v. injection. Furthermore, the DOX-loaded composites manifested enhanced in vivo anti-tumor therapeutic efficacy and sustainable circulation time of more than 5 h, which were favorable for imaging measurement. With the advantages of the designed composite system, the present experiments propose a strategy for developing a new multiple imaging-drug delivery-local therapy platform for synergistic diagnosis and therapy.

《Iridium(III) complex-containing non-conjugated polymers for non-volatile memory induced by switchable through-space charge transfer》 was written by Yang, Baojie; Tao, Peng; Ma, Chenxi; Tang, Runze; Gong, Tao; Liu, Shujuan; Zhao, Qiang. Related Products of 627-18-9 And the article was included in Journal of Materials Chemistry C: Materials for Optical and Electronic Devices in 2020. The article conveys some information:

Organic memory devices have recently attracted considerable interest to combat the increasing demands of data storage. Herein, taking advantage of the electron-deficient nature of iridium(III) complexes and the flexible polymer skeleton of non-conjugated polymers, a series of novel non-conjugated iridium(III) complex-containing polymers P2-P5 with non-volatile memory properties, and the corresponding model polymer P1, were rationally designed and synthesized. The memory effect of P1 is a static random-access memory type, while that of the polymers containing iridium(III) complexes are flash types. The ON/OFF current ratio of the devices based on P3 is as high as 103 and the device has good stability. It exhibits a long retention time of 104 s and both ON and OFF states, which survive up to more than 105 read cycles. The introduction of an iridium(III) complex contributes to the charge-transfer states from carbazole moieties to the iridium(III) complex, which also improves the crystallinity of polymers and realizes elec. bistability. In the part of experimental materials, we found many familiar compounds, such as 3-Bromopropan-1-ol(cas: 627-18-9Related Products of 627-18-9)

Cannabis and crash risk among older drivers

The purpose of this research was to reanalyze data collected from the National Highway Traffic Safety Administration’s Drug and Alcohol Crash Risk Study to investigate whether driving under the influence of cannabis (THC-positive) was associated with elevated crash risk for younger and older drivers. The data came from a case-control relative risk study collected from Virginia Beach, VA, over a 20-month period. Data collectors gathered driver information from the scene of vehicle crashes and, in some cases, from hospitals. Non-crash controls were sampled from the same locations, days, and times as crashes. Key data items included driver demographics and oral fluid and blood samples, which were assayed for licit and illicit drugs. We found no overall association between cannabis use and risk of crash involvement. However, when age and age(2) were allowed to interact with THC, significant interaction effects emerged. THC was associated with increased risk of crash involvement for older drivers. Difference between THC-positive and sober drivers emerged as significant at age 64. The research underscores the value of examining drugged driving in the context of driver age. Age-related declines in neurocognitive and psychomotor functioning were not measured but might be important in explaining the results.
