This review introduces the spinning disk reactor and emphasises its suitability for all aspects of polymer chemistry. The literature reviewed includes university theses, as well as key patent and openly published literature; it is not an exhaustive collation of the literature to date. The spinning disk reactor (SDR) i…
In this work, three new quinacridone-based dyes containing a furan moiety (QA1–3) have been synthesized through simple synthetic routes for the application of dye-sensitized solar cells (DSSCs). Their absorption spectra, electrochemical, photovoltaic properties and the cell long-term stability have been extensively in…
Highly-porous structures of activated carbon were prepared from oil palm shell. Their adsorptive characteristics and surface chemistry were investigated. Five series of activated carbons were obtained at different temperatures using chemical activation with potassium hydroxide. The results show that the activated carb…
A series of linear and star-shaped pyrazine-containing acene molecules 1a-b, 2a-b and 3 substituted by dicarboximide groups are synthesized via condensation reactions between o-diamine and dione. High electron affinity (up to 4.01 eV) is achieved due to the introduction of an electron-deficient pyrazine moiety and the…
The Bi2O3 quantum dots decorated nitrogen doped Bi3NbO7 nanosheets (Bi2O3/N-Bi3NbO7) were successfully synthesized via a facile in situ hydrothermal process as a straightforward protocol. The peony-like N-Bi3NbO7 hierarchical architectures decorated with surface enrichment of Bi2O3 quantum dots were characterized by X…
The present work compares the time-dependent evolution of the surface morphology during the horizontal acidic etching of diamond wire (DW) and SiC slurry (SP) sawn single-crystalline wafer by means of scanning electron microscopy (SEM), confocal microscopy, reflectivity measurements, and the measurement of the etch ra…
A 6,8-connected 3-dimensional metal–organic framework (2) of the tph topology was constructed from a new aromatic-rich, tetraphenylmethane-derived octa-carboxylate bridging ligand and trizinc cluster secondary building units (SBUs), and exhibited exceptionally high hydrogen (58 mg g−1 and 39 g L−1 at 52 bar and 77 K)…
Rational design and engineering of materials and/or structures for novel electrodes leading to next-generation lithium-ion batteries with high energy and power densities is a major challenge to the ever-growing needs of the electronic and automobile industries. To tackle this issue, we have designed a new type of 3D a…
MnO2/graphene oxide (GO) composite nanosheets have been successfully fabricated by a simple wet-chemical synthetic route. The composition and structure of the resulting MnO2/GO composites were characterized by transmission electron microscopy (TEM), energy dispersive X-ray diffraction (EDX), Fourier-transform infrared…
Single-crystalline β-Ni(OH)2 ultrathin nanosheets were synthesized via a simple electrochemical reaction of Ni electrodes with a mixed solution of NaCl, NaOH, and NH4Cl at room temperature. The average thickness of β-Ni(OH)2 nanosheets is in the range 1–15 nm, which can be readily tuned by changing the concentration o…
Solvent-induced chiral single-crystal to achiral single-crystal structural transformation is presented by two isomeric amino-functionalized metal-organic frameworks with 2-fold interpenetrating diamond topology, and the achiral form has high CO(2) uptake capacity.
Cocrystals of a nonionizable, water soluble compound (gababentin lactam (GBPL)) with less soluble coformers, are shown to be 2 to 17 times less soluble than GBPL. Cocrystals of GBPL with gentisic acid, 4-hydroxybenzoic acid, 4-aminobenzoic acid and fumaric acid are characterized by carboxylic acid---amide hydrogen bon…
Superparamagnetic Ag@Fe(3)O(4) nanospheres with core-shell nanostructures have been prepared by a facile one-pot method. The diameter of the as-synthesized nanospheres was about 200 nm and the core sizes were between 50 and 100 nm. By varying the concentrations, particles with tunable core size and total size are succ…
We describe here the discovery of a new class of organic cages assembled from simple tri- and dithiol building blocks using dynamic combinatorial chemistry (DCC). These water-soluble disulfide-linked architectures containing up to eleven components are only generated upon templation by positively charged polyamine gue…
An active-site-accessible porous metal-organic framework from self-assembling of trinuclear Cu(II) building units exhibits high CO oxidation activity and significant antiferromagnetic behavior.
A Co2+ ion was reduced by NaBH4 to form cobalt nanoparticles of 10–20 nm in size. The as-obtained Co nanoparticles were stable in air. Congo red was used to evaluate the Co nanoparticles' wastewater treatment capability. It was found that 150 ppm of Congo red could be removed from aqueous solution within 2 min with th…
Time-resolved fluorescence spectra from the RuN719 dye exhibit very short lifetimes (<30 fs) in solutions, on non-injecting substrates and on injecting ones. This reveals <10 fs intramolecular energy redistribution competing with the injection. We conclude that injection proceeds on a sub-10 fs time scale from non-the…
Vertically aligned single crystal TiO2 nanowire arrays grown on transparent conductive substrates are of considerable interest for use as photoanodes in dye-sensitized solar cells because they can provide direct pathways that ensure the rapid collection of charge carriers generated throughout the cells. However, growt…
Furan-based porous organic frameworks (FOFs) were prepared by condensation of biomass-derived 2,5-diformylfuran (DFF) and diamines via the formation of imine linkages, which are insoluble in water and common organic solvents and can keep stable around 300 °C under N2 atmosphere. The materials obtained by DFF being con…
The monodisperse triclinic WO3 nanoparticles with exposed (001), (100) and (010) facets have been successfully synthesized via a simple hydrothermal route with the assistance of tartaric acid. The percentage of exposed facets can be regulated by changing the amount of tartaric acid. On the bases of the structural anal…
