Lightweight, flexible and highly sensitive segregated microcellular nanocomposite piezoresistive sensors for human motion detection

Lightweight, flexible and highly sensitive piezoresistive sensors are promising for future generations of wearable electronics, artificial intelligence, human-computer interaction and soft robotics. Herein, segregated micro-cellular nanocomposites based on the microcellular poly(ether-block-amide) beads coated with silver (microcellular Pebax@Ag beads) are fabricated by the scalable and feasible supercritical CO2 foaming combined with dip-coating and curing approach. The segregated microcellular nanocomposites show low mass density (0.6 g/cm(3)), good flexibility (60% compressibility) and high electrical conductivity (0.64 S/m) with ultralow percolation threshold (0.28 vol%) benefiting from the simultaneous incorporation of segregated structures and microcellular structures. The resultant segregated microcellular nanocomposite piezoresistive sensors exhibit superior piezoresistive performances including improved relative resistance changes and higher sensitivity upon the externally applied compression strains owing to the synergistic effect of multiple mechanisms: higher local effective MWCNT contents due to the excluded-volume effect, construction of more effective 3D MWCNT/Ag conductive networks and rapid response due to the highly-resilient microcellular Pebax beads. Furthermore, the segregated microcellular nanocomposite piezoresistive sensors show outstanding long-term durability and working stability upon the repeated compression strains. Practical applications of the segregated microcellular nanocomposite piezoresistive sensors in functional sole materials have been verified for human motion detection during walking, implying their outstanding potential for burgeoning applications such as wearable electronics, artificial intelligence, human-computer interaction and soft robotics.

Direct conversion of ester bond-rich waste plastics into hard carbon for high-performance sodium storage

Disordered hard carbon (HC) has shown potential as the most promising anode materials for sodium-ion batteries (SIBS). Pyrolyzing waste plastics is a sustainable alternative to obtain HC. However, most plastics will completely decompose without carbon residue or transform into highly graphitic carbon during the carbonation process because of lacking oxygen functional groups. Hence, ester bond-rich waste engineering plastics, polycarbonate (PC), and polyethylene terephthalate (PET) were selected and directly converted into HC by a simple pyrolysis method. The PC and PET-derived carbon anodes (PC-HC and PET-HC) exhibit high reversible capacities of 327 and 342 mAh.g(-1) at 20 mA.g(-1) with remarkable initial coulombic efficiency (ICE) of 84.7% and 86.1%, respectively. Particularly, the carbon samples have no severe capacities decay after 140 cycles at 100 mA.g(-1). This work provides a cost-effective, easily large-scale, and eco-friendly route to fabricate HC anodes for grid-scale energy storage. (C) 2020 Elsevier Ltd. All rights reserved.

Rapid separation and purification of two C25 steroids with bicyclic [4.4.1] A/B rings from the marine fungus Aspergillus sp. LS116 by high-speed counter-current chromatography in stepwise elution mode

Two C25 steroids with bicyclic [4.4.1] A/B rings were successfully separated from the marine fungus Aspergillus sp. LS116 by a two-step high-speed counter current chromatography (HSCCC). Petroleum ether/ethyl acetate/methanol/water (5.5:11:5:7, v/v) and petroleum ether/ethyl acetate/methanol/water (5:6:5:7, v/v) were selected as two optimum two-phase systems to purify two C25 steroids, neocyclocitrinol B (1) and threo-23-O-methylneocyclocitrinol (2). The purity of two compounds was over 94%. Their structures were determined by comprehensive spectroscopic techniques. This is the first report about rapid separation and identification of C25 steroids with bicyclic [4.4.1] A/B rings by HSCCC.

Size-control in the synthesis of oxo-bridged phosphazane macrocycles via a modular addition approach

Cyclodiphosphazane macrocycles have demonstrated promising host-guest chemistry, but synthetic routes to highorder versions are lacking. Here the authors synthesise high-order oxygen-bridged phosphazane macrocycles via a modular cyclisation strategy. Inorganic macrocycles remain largely underdeveloped compared with their organic counterparts due to the challenges involved in their synthesis. Among them, cyclodiphosphazane macrocycles have shown to be promising candidates for supramolecular chemistry applications due to their ability to encapsulate small molecules or ions within their cavities. However, further developments have been handicapped by the lack of synthetic routes to high-order cyclodiphosphazane macrocycles. Moreover, current approaches allow little control over the size of the macrocycles formed. Here we report the synthesis of high-order oxygen-bridged phosphazane macrocycles via a 3 + n cyclisation (n = 1 and 3). Using this method, an all-P-III high-order hexameric cyclodiphosphazane macrocycle was isolated, displaying a larger macrocyclic cavity than comparable organic crown-ethers. Our approach demonstrates that increasing building block complexity enables precise control over macrocycle size, which will not only generate future developments in both the phosphazane and main group chemistry but also in the fields of supramolecular chemistry.

Polythiourethanes Crosslinked with Dynamic Disulfide Bonds: Synthesis via Nonisocyanate Approach, Thermomechanical and Reprocessing Properties

Polythiourethanes (PTUs) crosslinked with dynamic disulfide bonds are synthesized via a nonisocyanate approach. First, a difunctional five-membered cyclic trithiocarbonate (1) is synthesized via the reaction of diglycidyl ether of bisphenol A (DGEBA) with carbon disulfide (CS2). Thereafter, the step-growth polymerizations of 1 with alpha,omega-diamino poly(propylene oxide)s with various molar masses are carried out to obtain a series of linear poly(mercapto thiourethane)s. These linear poly(mercapto thiourethane)s are readily crosslinked upon formation of disulfide bonds, which are generated via radical coupling reaction with the side mercapto groups. These crosslinked PTUs can be tailored into the materials from thermosetting plastics to crosslinked elastomers, depending on the molar masses of alpha,omega-diamino poly(propylene oxide)s. More importantly, these crosslinked PTUs display excellent reprocessing properties at elevated temperatures, which is attributable to the metathesis reaction of dynamic disulfide bonds.

Furfural biotransformation in Acinetobacter baylyi ADP1 and Acinetobacter schindleri ACE

Objectives To determine furfural biotransformation capabilities of Acinetobacter baylyi ADP1 and Acinetobacter schindleri ACE. Results Acinetobacter baylyi ADP1 and A. schindleri ACE could not use furfural as sole carbon source but when acetate was used as substrate, ADP1 and ACE biotransformed 1 g furfural/l in 5 and 9 h, respectively. In both cases, the product of this biotransformation was difurfuryl-ether as shown by FT-IR and H-1 and C-13 NMR spectroscopy. The presence of furfural decreased the specific growth rate in acetate by 27% in ADP1 and 53% in ACE. For both strains, the MIC of furfural was 1.25 g/l. Nonetheless, ADP1 biotransformed 2 g furfural/l at a rate of 1 g/l/h in the stationary phase of growth. A transcriptional analysis of possible dehydrogenases involved in this biotransformation, identified that the areB and frmA genes were highly overexpressed after the exposure of ADP1 to furfural. The products of these genes are a benzyl-alcohol dehydrogenase and an alcohol dehydrogenase. Conclusions Acinetobacter baylyi ADP1 is a candidate for the biological detoxification of furfural, a fermentation inhibitor present in lignocellulosic hydrolysates, with the possible direct involvement of the AreB and FrmA enzymes in the process.

Application of 93-04-9, These common heterocyclic compound, 93-04-9, name is 2-Methoxynaphthalene, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.

EXAMPLE 1 The following is a procedure for preparing 2-methoxy-6-ethylnaphthalene by the transethylation of 2-methoxynaphthalene. To a 250 ml., 3-neck, round-bottom flask equipped with a magnetic stirrer and a sparge tube were added 70 g of mixed diethylbenzenes obtained from the Aldrich Chemical Company, Milwaukee, Wis. After cooling the reaction mixture with an ice bath, hydrogen chloride gas was added for three minutes and thereupon 14.48 grams of aluminum chloride were slowly added. Hydrogen chloride gas was again added for three minutes. The reaction flask was then placed in a hot water bath to raise the temperature of the reaction mixture to 85-90 C. At this point ethylene gas was sparged into the reaction mixture until the level of tetraethylbenzene in the reaction mixture was maximized. The composition of the mixture was monitored by gas chromatography. After the ethylene addition was stopped, the reaction mixture was stirred for an additional 30 minutes at 90 C. To the above reaction mixture at 15 C. was added a mixture of 29.02 grams of 2-methoxynaphthalene dissolved in 50 ml of dichloromethane. The reaction mixture was permitted to warm to room temperature and after 900 minutes it was heated to 32 C. using a water bath. After 15 hours total reaction time the yield of 2-methoxy-6-ethylnaphthalene was 71.5% as measured by gas chromatography. This example shows the high yield of 2-methoxy-6-ethylnaphthalene that can be achieved by the method of this invention.

Statistics shows that 2-Methoxynaphthalene is playing an increasingly important role. we look forward to future research findings about 93-04-9.
