Facile and rapid fractionation of bamboo wood with a p-toluenesulfonic acid-based three-constituent deep eutectic solvent

Here, we report a strategy with the application of p-toluenesulfonic acid (p-TsOH) based three-constituent deep eutectic solvent (3c-DES) for the efficient fractionation of bamboo wood towards its main components. Three kinds of deep eutectic solvents (DESs), including choline chloride (ChCl)/ ethylene glycol (EG)/p-TsOH, tetrabutylammonium chloride (N4Cl)/EG/p-TsOH and tetrapmpylammonium chloride (N3Cl) /EG/ p-TsOH, were facilely prepared and assessed for the pretreatment of bamboo wood. ChCl-EG-p-TsOH (molar ratio of 1:0.5:1) was found to be the most effective, evidenced by more than 93.36% xylan and 90.32% lignin removals with most of the cellulose (86.73%) retained in the pretreated bamboo in a short time of 10 min at 100 degrees C and a 10 wt. % solid loading, which significantly improved delignification by more than 85% compared with that of using ChCl-EG (molar ratio of 1:2) as a two-constituent at the same conditions. The 3c-DES pretreatment resulted in the desirable deconstruction of the recalcitrant of cell walls in woody biomass, evidenced by the higher glucose yield of 90.2% by the enzymatic hydrolysis of the cellulose-rich substrate, which was nearly four-fold higher than that of the untreated bamboo. The extracted lignin showed high purity (95%) with a moderate and homogeneous molecular weight, showing promising potential applications in the downstream production of biochemicals and biomaterials. Furthermore, the 3c-DES exhibited excellent recoverability by evaluating the fractionation efficiency and enzymatic hydrolysis performance with the recycled DES. The results from this study demonstrated that p-TsOH-based 3c-DES showed practical significance for the fast and effective fractionation of woody biomass for high-quality components.

Expression profiling of endo-xylanases during ripening of strawberry cultivars with contrasting softening rates. Influence of postharvest and hormonal treatments

BACKGROUND Softening is one of the main features that determine fruit quality during strawberry (Fragaria x ananassa, Duch.) ripening and storage. Being closely related to textural changes, the molecular and biochemical bases underlying strawberry cell-wall metabolism is a matter of interest. Here we investigated the abundance of transcripts encoding putative strawberry endo-xylanases in plant tissues, during fruit ripening and under postharvest and hormonal treatments. Total xylanase activity and expression of related genes in strawberry varieties with contrasting firmness were analyzed. RESULTS FaXynA and FaXynC mRNA abundance was significantly higher than FaXynB in each plant tissue studied. Higher total xylanase activity was detected at the end of the ripening of the softer cultivar (‘Toyonoka’) in comparison with the firmer one (‘Camarosa’), correlating with the abundance of FaXynA and FaXynC transcripts. Postharvest 1-methylcyclopropene treatment up-regulated FaXynA and FaXynC expressions. FaXynC mRNA abundance decreased with heat treatment but the opposite was observed for FaXynA. Calcium chloride treatment down-regulated FaXynA and FaXynC expression. Both genes responded differently to plant growth regulators’ exposure. FaXynC expression was down-regulated by auxins and gibberellins treatment and up-regulated by abscisic acid. FaXynA was up-regulated by auxins, while no changes in mRNA levels were evident by abscisic acid and gibberellins treatment. Ethephon exposure did not change FaXynA and FaXynC expressions. CONCLUSION New knowledge about the presence of xylanases in ripening strawberry fruit and their response to postharvest and hormonal treatments is provided. Our findings suggest a role for endo-xylanases in hemicelluloses depolymerization and possibly in strawberry fruit softening. (c) 2020 Society of Chemical Industry

Fabrication of omniphobic PVDF composite membrane with dual-scale hierarchical structure via chemical bonding for robust membrane distillation

In recent years, omniphobic membranes have drawn much attention due to the strong repellence to various liquids. In this study, a PVDF composite membrane with omniphobic characteristics was prepared by constructing dual-scale hierarchical structure and introducing long chemical chains with the low surface energy. The special architecture was derived from the immobilization of TiO2 @PDA@Cu composite nanoparticles on the surface via chemical bonding, and the fluorosilanization treatment with 1H,1H,2H,2H-perfluorodecyltriethoxysilane for membrane surfaces. A series of characterizations were implemented to explore composite nanoparticles’ morphology and composition, as well as membrane morphology and surface analysis. In addition, antifouling and anti-wetting behaviors of pristine and composite membranes were investigated by successive direct contact membrane distillation (DCMD) experiments, in which different contaminations containing inorganic salts, organic matter, surfactants and mineral oil were chosen as the feed. The results displayed that composite nanoparticles were obtained through the chelating effect of polydopamine (PDA) and the dual-scale structure was realized with the assistance of trimesoyl chloride (TMC). The omniphobic membrane exhibited strong repulsive forces to various liquids, such as water, SDBS solution (0.4 mM), CTAB solution (0.4 mM), tween-20 solution (0.4 mM) and mineral oil emulsion (0.2% v/v) with the contact angles of 168.0 +/- 2.0 degrees, 157.1 +/- 1.5 degrees, 160.0 +/- 1.2 degrees, 158.3 +/- 1.5 degrees and 152.5 +/- 3.0 degrees, respectively. Furthermore, compared to pristine membrane, the omniphobic membrane presented superior stability, higher salt rejection rate and excellent anti-wetting and anti-fouling performances in the DCMD tests. Thus, the composite membrane with superhydrophobic and superoleophobic features possessed great application potential for high salinity wastewater treatment in membrane distillation.

1, 10-phenanthroimidazole derivatives as efficient corrosion inhibitors for mild steel in 1 M HCl: synthesis, gravimetric, electrochemical and theoretical investigation

The anticorrosive performances of 1,10-phenanthroimidazole derivatives 2-phenyl-1H-imidazo[4,5-f][1,10]phenanthroline (IPB) and 1,4-di (1H-imidazo [4,54] [1,10] phenanthrolin-2-yl)benzene (DIPB) for mild steel (MS) in 1 M HCl media were surveyed via gravimetric, electrochemical and thermodynamic calculation methods. IPB and DIPB could adsorb spontaneously on the MS by two adsorption modes with predominant chemisorption, and the process obeyed Langmuir adsorption isotherm. Furthermore, IPB and DIPB were mixed-type inhibitors. Meanwhile, the UV-vis absorption spectroscopy was used to investigate the forming of complex between inhibitor and Fe. The structure-activity relationship was also discussed by means of theoretical calculation. Those results demonstrate that this type of compounds with multiple active sites exhibit great potential in corrosion inhibition of MS in acidic media. (C) 2020 Elsevier B.V. All rights reserved.

Conducting Polyetheretherketone Nanocomposites with an Electrophoretically Deposited Bioactive Coating for Bone Tissue Regeneration and Multimodal Therapeutic Applications

The use of polyetheretherketone (PEEK) has grown exponentially in the biomedical field in recent decades because of its outstanding biomechanical properties. However, its lack of bioactivity/osteointegration remains an unresolved issue toward its wide use in orthopedic applications. In this work, graphene nanosheets have been incorporated into PEEK to obtain multifunctional nanocomposites. Because of the formation of an electrical percolation network and the pi-pi* conjugation between graphene and PEEK, the resulting composites have achieved 12 orders of magnitude enhancement in their electrical conductivity and thereby enabled electrophoretic deposition of a bioactive/ antibacterial coating consisting of stearyltrimethylammonium chloride-modified hydroxyapatite. The coated composite implant shows significant boosting of bone marrow mesenchymal stem cell proliferation in vitro. In addition, the strong photothermal conversion effect of the graphene nanofillers has enabled laser-induced heating of our nanocomposite implants, where the temperature of the implant can reach 45 degrees C in 150 s. The unique multifunctionality of the implant has also been demonstrated for photothermal applications such as enhancing bacterial eradication and tumor cell inhibition, as well as bone tissue regeneration in vivo. The results suggest the strong potential of our multifunctional implant in bone repair applications as well as multimodal therapy of challenging bone diseases such as osteosarcoma and osteomyelitis.

Combination of temperature-assisted ternary phase homogenous liquid-liquid extraction with deep eutectic solvent-based dispersive liquid-liquid microextraction for the extraction of phytosterols from cow milk and cream samples

A three-phase homogenous liquid-liquid extraction method followed by deep eutectic solvent-based dispersive liquid-liquid microextraction has been used for the extraction and preconcentration of some phytosterols from cow milk and cream samples. In this method, cow milk or melted cream was transferred into a glass test tube and a mixture of sodium hydroxide solution (as fatty acids saponification agent) and acetonitrile (as extraction/dispersive solvent) was added to the solution. The mixture was shaken manually and placed in a water bath. After dissolving sodium chloride and centrifugation, the obtained supernatant phase (acetonitrile) was removed and mixed with ethyl methyl ammonium chloride: phenyl acetic acid deep eutectic solvent at microliter level. Under optimum conditions, low limits of detection (1.6-4.1 mu g/L) and quantification (5.3-13.1 mu g/L), high enrichment factors (138-207), and extraction recoveries (55-83%), and good precision (relative standard deviations <= 6.8%) can be obtained. The method was done on different milk and cream samples and the results showed that total phytosterols level in all samples were in the permitted level established by the National Standard Organization Guidelines, except for three cream samples.

A Replacement Reaction Enabled Interdigitated Metal/Solid Electrolyte Architecture for Battery Cycling at 20 mA cm(-2) and 20 mAh cm(-2)

Metal anodes represent as a prime choice for the coming generation rechargeable batteries with high energy density. However, daunting challenges including electrode volume variation and inevitable side reactions preclude them from becoming a viable technology. Here, a facile replacement reaction was employed to fabricate a three-dimensional (3D) interdigitated metal/solid electrolyte composite electrode, which not only provides a stable host structure for buffering the volume change within the composite but also prevents side reactions by avoiding the direct contact between active metal and liquid electrolyte. As a proof-of-concept demonstration, a 3D interdigitated zinc (Zn) metal/solid electrolyte architecture was fabricated via a galvanic replacement reaction between Zn metal foil and indium (In) chloride solution followed by electrochemical activation, featuring the interdigitation between metallic Zn and amorphous indium hydroxide sulfate (IHS) with high Zn2+ conductivity (56.9 +/- 1.8 mS cm(-1)), large Zn2+ transference number (0.55), and high electronic resistivity [(2.08 +/- 0.01) x 10(3) Omega cm]. The as-designed Zn/IHS electrode sustained stable electrochemical Zn plating/stripping over 700 cycles with a record-low overpotential of 8 mV at 1 mA cm(-2) and 0.5 mAh cm(-2). More impressively, it displayed cycle-stable performance with low overpotential of 10 mV under ultrahigh current density and areal capacity (20 mA cm(-2), 20 mAh cm(-2)), which outperformed all the reported Zn metal electrodes in mild aqueous electrolyte. The fabrication of interdigitated metal/solid electrolyte was generalized to other metal pairs, including Zn/Sn and Zn/Co, which provide inspiration for next-generation Zn metal batteries with high energy density and reversibility.

Unexpected Boosted Solar Water Oxidation by Nonconjugated Polymer-Mediated Tandem Charge Transfer

Conjugated polymers are deemed as conductive carrier mediators for engendering the pi electrons along the molecular framework, while the role of nonconjugated insulated polymers has been generally overlooked without the capability to participate in the solar-powered oxidation-reduction kinetics and charge-transfer process. Alternatively, considering the ultrashort charge lifetime and significant deficiency of metal nanocluster (NC)-based photosystems, the fine tuning of charge migration over atomically precise ultrasmall metal NCs as novel light-harvesting antennas has so far not yet been unleashed. Here, we unlock the charge-transfer capability of a nonconjugated polymer to modulate the charge flow over metal NCs (Au-x and Au-25) by such a solid-state nonconductive polymer via a conceptually new chemistry strategy by which l-glutathione (GSH)-capped gold (Au-x@GSH) NCs and poly(diallyl-dimethylammonium chloride) (PDDA) were alternately self-assembled on the metal oxide (MO: WO3, Fe2O3, and TiO2) substrates. The ultrathin nonconjugated PDDA interim layer periodically intercalated in-between Au-x (Au-25) NC layers concurrently serves as an unexpected charge-transfer mediator to foster the unidirectional electron flow from Au-x(Au-25) NCs to MOs by forming a tandem charge-transfer chain, hence endowing the multilayered MO/(PDDA-Au-x)(n) heterostructures with significantly boosted photoelectrochemical water oxidation performance under light irradiation. The unanticipated role of PDDA as a cascade charge mediator is demonstrated to be universal. Our work would unlock the potential charge-transport capability of nonconjugated polymers as a novel charge mediator for solar-to-chemical conversion.

Approach to generating the right active phase in the Direct synthesis of trimethoxysilanes using the CuCl-Cu2O catalyst

The direct synthesis of trimethoxysilane (M3) by the reaction of Si with methanol over the Cud catalyst often generates a large amount of erosive HCl gas, causing severe environmental pollution. Thus, it calls for the development of greener and more efficient composite catalysts. In this work, to reduce the amount of CuCl, we employed three pretreatment methods to activate the contact mass of Si powder and the composite catalyst of CuCl and Cu2O. It was found that the contact mass activated by argon (Ar), hydrogen argon (H-2/Ar) and methyl chloride (CH3Cl), respectively, exhibited different catalytic performances: the highest Si conversion (34.1%) and M3 yield (24.0%) were obtained on the sample activated by CH3Cl. Notably, the M3 yield was increased 8-fold than that of the un-activated sample. The X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) studies revealed that different activation methods led to the generation of different kinds of CuxSi phases, such as Cu3Si and Cu4Si, both of which gradually transformed into Cu15Si4 during the reaction process. Pretreatment of the contact mass with CH3Cl promoted the formation of CuxSi, which contributed to the generation of more Cu15Si4 active phase, and finally to the superior catalytic performance.

Fabrication of Microporous Polymeric Film via Colloid-Based Layer-By-layer Technology for CO2 Capturing

Large-scale and simple strategies to flexibly preparing materials with industrial application potential attract people’s attention. Layer-by-layer (LBL) self-assembly technology is a typical preparation method for current nanomaterials to address the large-scale concern and achieve the possibility of a simple, streamlined and controllable process. Here, a novel and simple strategy is developed to fabricate microporous polymeric film (MPF) based on poly(styrene-hydroxyethyl methylacrylate) (P(St-HEMA)) microspheres, in combination with LBL self-assembly technology and hypercrosslinked microporous post-treatment. To improve the mechanical properties of the film, the buffer layer of polyethyleneimine (PEI) and poly(sodium-p-styrenesulfonate) (PSS) are used to avoid swelling of nanoparticles and the methacryloxyethyltrimethyl ammonium chloride (DMC) is chosen to increase the force between the nanoparticles via UV-crosslinking. The MPF has well CO2 capture capabilities up to 46.21 wt% (10.52 mmol g(-1)), large-scale feature and certain improved mechanical properties. It is hoped that the research could display a successful strategy to prepare the large-scale film for the application of industrialization.
