BACKGROUND: Thermochemical pretreatment of lignocellulose is crucial to bioconversion in the fields of biorefinery and biofuels. However, the enzyme inhibitors in pretreatment hydrolysate make solid substrate washing and hydrolysate detoxification indispensable prior to enzymatic hydrolysis. Sulfite pretreatment to ov…
Graphene oxide (GO) has many exciting advantages such as easy preparation, low toxicity, good solubility and stability in aqueous solution. However, GO itself has a low near-infrared (NIR) absorption, and thus is not suitable for photothermal therapy and photoacoustic imaging. To overcome this limitation, a novel dye-…
Formic acid (FA) holds great potential as a convenient source of hydrogen for sustainable chemical synthesis and renewable energy storage. Herein, the non-noble metal nickel (Ni) exhibits superior promoting effect in improving the catalytic activity of Pd toward high activity and selectivity for FA decomposition at ro…
UiO-66 incorporated monoliths were fabricated to enhance the liquid chromatographic separation of small molecules with high column efficiency and good reproducibility.
Biocompatible and sustainable electronic-grade materials are integral for the development of electronics for biointegration and ‘use-and-throw’ applications. Herein we report the use of the natural resin shellac in organic field-effect transistors. Shellac was employed to cast robust and smooth substrates suitable for…
Nano-sized ceramic fillers provide a promising approach to enhancing polymer electrolytes in terms of the interfacial chemistry, ionic conductivity, and C-rate performance of Li-ion cells, if their dispersibility and compatibility in a polymer matrix can be well managed. In this work, a nano-crystalline TiO2–PMMA hybr…
We report a density functional theory (DFT) study of microscopic detailed effects of the bonding configuration of nitrogen-doped graphene (N-graphene) within the carbon lattice (including pyridinic, pyrrolic, and graphitic N) on the reactivity and mechanistic processes of H2O2 reduction reaction. We simulated the adso…
The synthesis of stable bicontinuous hierarchically porous metal–organic frameworks (MOFs) is described. Two functional block co-oligomer templates were used independently, i.e. poly(styrene)-block-poly(4-vinylpyridine) and poly(styrene)-block-poly(acrylic acid). Two prototypical MOFs, ZIF-8 and HKUST-1, were selected…
A donor–acceptor–donor (D–A–D) molecule di(triphenylamine)-thiazolothiazole 1 has been employed in which the central Lewis-basic nitrogen atoms prompt it to be responsive to strong acids in both solution and solid states. As a result, the electron-accepting strength and intramolecular charge transfer (ICT) character c…
The liquid phase selective hydrogenation of phenol to cyclohexanone has been investigated over polymeric mesoporous graphitic carbon nitride (mpg–C3N4) supported Pd catalysts (Pd@mpg-C3N4). This Pd@mpg-C3N4 is shown to be highly active and promotes the selective formation of cyclohexanone (∼99%), an industrially impor…
A versatile and simple methodology for the preparation of well-defined polyglutamate nanocarriers is described. For the first time ammonium salts with non-nucleophilic tetrafluoroborate anions are used as initiators for the ring opening polymerization of α-N-carboxyanhydrides (NCAs) allowing a multigram scale polyglut…
We demonstrate plasmonic enhancement of visible-light-driven splitting of water at three-dimensionally (3D) networked gold-titania (Au-TiO2) aerogels. The sol-gel-derived ultraporous composite nanoarchitecture, which contains 1 to 8.5 wt% Au nanoparticles and titania in the anatase form, retains the high surface area…
Over the last decades, iodine-free redox couples have been widely investigated as alternatives for the ubiquitous triiodide/iodide redox shuttle in dye-sensitized solar cells (DSCs). This is mainly motivated by desires to overcome the disadvantages associated with the latter, such as large energy loss in the dye regen…
SiO has been considered as one of the most promising anodes, the reaction mechanism of SiO with Li is still not well understood. High energy mechanical milling (HEMM) followed by etching of the SiO surface with NaOH solution was carried out in this study to enhance cycle performance. X-ray photoelectron spectroscopy (…
IAST calculations reveal that sulfonate ammonium salt grafting renders porous polymer networks (PPN-6-SO3NH4) with exceptionally high adsorption selectivity for CO2 over N2 and CO2 over CH4. Breakthrough experiments confirm the high CO2 adsorption capacity (1.7 mmol g−1, 75 mg g−1) by feeding 15% CO2 balanced with N2…
A novel and highly stable inclusion complex was formed between per-butylated pillar[6]arene and a ferrocenium cation, while the reduced form ferrocene only showed extremely weak binding affinity with per-butylated pillar[6]arene in organic solvents.
Two n-type W-containing ternary oxides, CuWO4 and Bi2WO6, were prepared as high surface area electrodes and characterized for use as photoanodes in a water-splitting photoelectrochemical cell. The synthesis involved electrochemical preparation of porous WO3 electrodes and annealing them with Cu2+- or Bi3+-containing s…
Metal-organic frameworks (MOFs) have extremely high surface areas and pore volumes, tunable pore sizes and chemical functionalities and are an interesting addition to the field of porous materials. One of the key challenges that needs to be overcome to elevate MOFs to the applied level is their sensitivity to humid en…
Mesoporous silica nanoparticles (MSNs) have been surface-functionalized with choline moieties encircled by sulfonatocalix[4]arenes. Two enzyme cleavable sites are incorporated in the stalks for specific enzymes to regulate the release of loaded cargos from MSNs. These gated materials show a clear enzymatic response an…
An evanescent-field-coupled waveguide-mode (EFC-WM) sensor utilizes monolithic SiO2/Si/SiO2 sensing plates having a multilayered structure and is used to evaluate a blocking agent comprising poly(ethylene glycol)-based block copolymers. Factor IX (FIX) protein was detected using its aptamer, viz. FIX was immobilized o…
