Reviewing the metabolome coverage provided by LC-MS: Focus on sample preparation and chromatography-A tutorial

Metabolomics has become an invaluable tool for both studying metabolism and biomarker discovery. The great technical advances in analytical chemistry and bioinformatics have considerably increased the number of measurable metabolites, yet an important part of the human metabolome remains uncovered. Among the various MS hyphenated techniques available, LC-MS stands out as the most used. Here, we aimed to show the capabilities of LC-MS to uncover part of the metabolome and how to best proceed with sample preparation and LC to maximise metabolite detection. The analyses of various open metabolite databases served us to estimate the size of the already detected human metabolome, the expected metabolite composition of most used human biospecimens and which part of the metabolome can be detected when LC-MS is used. Based on an extensive review and on our experience, we have outlined standard procedures for LC-MS analysis of urine, cells, serum/plasma, tissues and faeces, to guide in the selection of the sample preparation method that best matches with one or more LC techniques in order to get the widest metabolome coverage. These standard procedures may be a useful tool to explore, at a glance, the wide spectrum of possibilities available, which can be a good starting point for most of the LC-MS metabolomic studies.

Graphene oxide: An emerging electromaterial for energy storage and conversion

This paper gives a comprehensive review of the recent progress on electrochemical energy storage devices using graphene oxide (GO). GO, a single sheet of graphite oxide, is a functionalised graphene, carrying many oxygen-containing groups. This endows GO with various unique features for versatile applications in batteries, capacitors and fuel cells. Specific applications are considered principally including use in electrodes as the active materials to enhance the performance or as substrates to diversify the structures, in solid-state electrolytes and membranes to improve the ionic conductivity and mechanical properties, and in interlayers to protect the electrodes, membranes or current collectors. Furthermore, the challenges and future prospects are discussed in the paper for encouraging further research and development of GO applications.

Ag-modified hydrogen titanate nanowire arrays for stable lithium metal anode in a carbonate-based electrolyte

In the investigation of the next-generation battery anode, Li metal has attracted increasing attention owing to its ultrahigh specific capacity and low reduction potential. However, its low columbic efficiency, limited cycling life, and serious safety hazards have hindered the practical application of rechargeable Li metal batteries. Although several strategies have been proposed to enhance the electrochemical performance of Li metal anodes, most are centered around ether-based electrolytes, which are volatile and do not provide a sufficiently large voltage window. Therefore, we aimed to attain stable Li deposition/stripping in a commercial carbonate-based electrolyte. Herein, we have successfully synthesized hydrogen titanate (HTO) nanowire arrays decorated with homogenous Ag nanoparticles (NPs) (Ag@HTO) via simple hydrothermal and silver mirror reactions. The 3D cross-linked array structure with Ag NPs provides preferable nucleation sites for uniform Li deposition, and most importantly, when assembled with the commercial LiNi0.5Co0.2Mn0.3O2 cathode material, the Ag@HTO could maintain a capacity retention ratio of 81.2% at 1 C after 200 cycles, however the pristine Ti foil failed to do so after only 60 cycles. Our research therefore reveals a new way of designing current collectors paired with commercial high voltage cathodes that can create high energy density Li metal batteries.

Addition of modified hollow mesoporous organosilica in anhydrous SPEEK/IL composite membrane enhances its proton conductivity

Sulfonated hollow mesoporous organosilica (sHMO) was successfully prepared. SP/IL/sHMO-x (x = 2.5, 5.0, 7.5 and 10 wt%) composite membrane was synthesized by dispersing ionic liquid (IL) in sHMO, with sulfonated polyether ether ketone (SPEEK, SP) as the matrix. For comparison, unsulfonated HMO and SP/IL/HMO-x membranes were also prepared. The membranes were characterized by Fourier transform infrared spectroscopy (FT-IR), thermogravimetric (TG) analysis, dipping and AC impedance. FT-IR results showed no new chemical bond was formed among SPEEK, IL and organosilica, and the components were bound by intermolecular hydrogen bonding. The results of TG showed that the membranes were stable up to 240 degrees C. The IL loss study showed that the retention of IL increased with the increase of the content of organosilica, while sHMO composite membrane showed lower IL retention capacity than HMO composite membrane. Proton conductivity study showed that sHMO also contributed to the conductivity of the membrane. The conductivity of the SP/IL-30/sHMO-7.5membrane was 1.13 mS cm-(1 )at 200 degrees C, which is twice that of the SP/IL-30/HMO-7.5 (0.60 mS cm(-1)). At 200 degrees C, the conductivity of SPEEK/IL-50/sHMO-7.5 reached 10.5 mS cm(-1). The anhydrous composite membrane could be used in PEMFCs under medium temperature condition.

Occurrence and spatial distribution of legacy and novel brominated flame retardants in seawater and sediment of the South China sea

The occurrence and spatial distribution of polybrominated diphenyl ethers (PBDEs) and novel brominated flame retardants (NBFRs) in seawater and surficial sediment samples (N = 19 and 45, respectively) from the South China Sea (SCS) in 2018 were investigated, and the correlation between BFRs and site parameters (total organic carbon, depth, etc.) were assessed by principal component analysis. The concentration ranges of Sigma PBDEs in seawater and sediments were 0.90-4.40 ng/L and 0.52-22.67 ng/g dry weight (dw), respectively, while those of Sigma NBERs were 0.49-37.42 ng/L and 0.78-82.29 ng/g dw, respectively. BDE-209 and decabromodiphenyl ethane were the predominant BFRs, accounting for 38.65% and 36.94% in seawater and 26.71% and 68.42% in sediments, respectively. Notably, tris(2,3-dibromopropyl)isocyanurate and 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine, seldomly detected in aquatic matrices worldwide, were detected for the first time in the study area, and their relatively high levels and detection frequencies indicate the ubiquitous application of these NBFRs in the Pearl River Delta. Zhuhai and Jiangmen are the main sources of NBFRs in the SCS. Preliminary risk assessment on NBFRs using hazard quotient indicates low to medium risks to marine organisms at some sites. The occurrence of NBFRs in the SCS highlights the prioritization of more toxicological information on these compounds. (C) 2020 Elsevier Ltd. All rights reserved.

Enhanced interfacial properties of carbon fiber/epoxy composites by coating carbon nanotubes onto carbon fiber surface by one-step dipping method

A type of carbon fiber/carbon nanotubes (CF/CNTs) multi-scale reinforcement was prepared by one-step dipping method, in which silane coupling agent (3-glycidyl ether oxy-propyl trimethoxy silane, KH560) was used as the bridge between CF and CNTs. Results showed that CNTs were uniformly coated onto CF surface, and the surface chemical activity, wettability and single fiber tensile strength of modified CFs were all improved significantly. More importantly, the interfacial shear strength (IFSS) of CF/CNTs reinforced epoxy composite, CF/CNTs composite, observed by SEM, showed good interface adhesion. It was also found that the silane coupling agent and CNTs would enhance the interfacial properties synergistically. Besides, the bridging effect of CNTs as the interfacial reinforcing mechanism for CF/CNTs multi-scale reinforcement composite was put forward. This special reinforcing mechanism may be as the guiding principle for CF surface modification and interfacial properties enhancement.

Xeno-Free Bioreactor Culture of Human Mesenchymal Stromal Cells on Chemically Defined Microcarriers

Human mesenchymal stromal cells (hMSC), also called mesenchymal stem cells, are adult cells that have demonstrated their potential in therapeutic applications, highlighted by their ability to differentiate down different lineages, modulate the immune system, and produce biologics. There is a pressing need for scalable culture systems for hMSC due to the large number of cells needed for clinical applications. Most current methods for expanding hMSC fail to provide a reproducible cell product in clinically required cell numbers without the use of serum-containing media or harsh enzymes. In this work, we apply a tailorable, thin, synthetic polymer coating-poly(poly(ethylene glycol) methyl ether methacrylate-ran-vinyl dimethyl azlactone-ran-glycidyl methacrylate) (P-(PEGMEMA-r-VDM-r-GMA), PVG)-to the surface of commercially available polystyrene (PS) microcarriers to create chemically defined three-dimensional (3D) surfaces for large-scale cell expansion. These chemically defined microcarriers provide a reproducible surface that does not rely on the adsorption of xenogeneic serum proteins to mediate cell adhesion, enabling their use in xeno-free culture systems. Specifically, this work demonstrates the improved adhesion of hMSC to coated microcarriers over PS microcarriers in xeno-free media and describes their use in a readily scalable, bioreactor-based culture system. Additionally, these surfaces resist the adsorption of media-borne and cell-produced proteins, which result in integrin-mediated cell adhesion throughout the culture period. This feature allows the cells to be efficiently passaged from the microcarrier using a chemical chelating agent (ethylenediaminetetraacetic acid (EDTA)) in the absence of cleavage enzymes, an improvement over other microcarrier products in the field. Bioreactor culture of hMSC on these microcarriers enabled the production of hMSC over 4 days from a scalable, xeno-free environment.

Wettability alteration and retention of mixed polymer-grafted silica nanoparticles onto oil-wet porous medium

Enhanced oil recovery (EOR) processes are applied to recover trapped or residual oil in the reservoir rocks after primary and secondary recovery methods. Changing the wettability of the rock from oil-wet to water-wet is named wettability alteration. It is an important factor for EOR. Due to their unique properties, nanoparticles have gained great attention for improving oil recovery. Despite the promising results, the main challenges of applying nanoparticles are related to the colloidal stability of the nanofluids in the harsh conditions of the reservoirs. In recent years, polymer-grafted nanoparticles have been considered as novel promising materials for EOR. The obtained results showed that adding a hydrophobic agent trimethoxy (propyl) silane on the surface of modified silica nanoparticles with polyethylene glycol methyl ether has an effective role in improving retention and wettability alteration, especially in the oil-wet substrate due to hydrophobic interaction. The modified silica nanoparticle by mixed polyethylene glycol methyl ether (Mn similar to 5000) and trimethoxy (propyl) silane showed a proper performance at a concentration of 1000 ppm and a salinity range of 2000-40,000 ppm. The obtained findings can help for a better understanding of the silica nanofluid modification with both hydrophilic and hydrophobic agents for the EOR application of near-wellbore.

Green solvent pretreatment for enhanced production of sugars and antioxidative lignin from poplar

A promising pretreatment mediated by biomass-derived deep eutectic solvent (DES) with choline chloride to lactic acid was implemented to overcome the recalcitrant structure of poplar sawdust for effective enzymatic hydrolysis and valorized lignin. Results showed the DES applied was strongly selective towards removal of lignin and xylan while preserving cellulose. Under the optimal pretreatment condition (DES ratio: 1:2, temperature: 130 degrees C, time:1.5 h), the glucose yield from enzymatic hydrolysis was 75.8%. Chemical and structure changes of recovered lignin were evaluated to gauge its valorization potential. It indicated that the recovered lignin possessed molecular weight (4000-6000 g/mol), low polydispersity (PDI < 2.0), low quantity of beta-aryl-ethers with no recondensation, and an abundance of phenolic OH groups. The excellent antioxidant capacity of lignin demonstrated its great value as a polyphenolic antioxidant. Overall, this work demonstrated an emerging biorefinery technology method for effective fractionation and valorization of lignocellulosic biomass. But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 101-55-3, you can contact me at any time and look forward to more communication.

Experimental and numerical study on the effect of oxymethylene ether-3 (OME3) on soot particle formation

The reduction and control of particulate matter generated by fossil fuel combustion are among the main issues for actual and future combustion devices due to the increasingly stringent emission regulations. Recently, various fuels have been investigated as a potential substitute or additive for diesel and gasoline. This work focuses on how oxymethylene ether-3 (OME3), the smallest promising OME compound, affects carbon particulate formation when blended with ethylene in burner-stabilized premixed flames at different equivalence ratios. Particle size distribution (PSD) and Laser-Induced Fluorescence (LIF) and Incandescence (LII) along with numerical (Conditional Quadrature Method of Moments – CQMOM, based on D’Anna physico-chemical soot model) investigations were conducted to study particle formation and growth in pure ethylene and ethylene/OME3 flames. The soot volume fraction and PSD indicate a reduction in the total number and the size of the soot particles at all equivalence ratios, while the number of small nanoparticles remains almost unchanged. The CQMOM model is able to predict similar trends for the soot volume fraction and, using the entropy maximization concept, the general shape of the PSD for both pure ethylene and OME3-blended flames, compared to the experimental measurements. Further, carbon particulate matter was thermophoretically sampled in the highest equivalence ratio conditions and spectroscopically analyzed. The soot structure was investigated using UV-Visible and Raman spectroscopy, finding a slightly higher aromaticity for the pure ethylene soot. FTIR analysis showed that carbon particulate matter produced from an OME3-doped flame contained larger amounts of oxygen, mainly in the form of C-O.
