Photocatalysts consisting of porphyrin and graphene have been designed and applied to reduce CO 2 to C 2 H 2 under visible light, which is an excellent simulator of natural photosynthesis.
Silicon is a promising high capacity (4200 mA h g(-1)) anode material for lithium ion batteries but the significant volume change (over 300%) of silicon during lithiation/delithiation remains a challenge in terms of silicon pulverization and solid-electrolyte-interphase (SEI) accumulation in the silicon composite elec…
Co(OH) 2 arrays/GNSs composites, which are constructed by preferentially oriented growth, exhibit a high-performance when used as anode materials for lithium-ion batteries.
A density functional theory study of a cobalt(II) octaethylporphyrin (CoOEP) monolayer on Au(111) and HOPG(0001) surfaces was performed under periodic boundary conditions. Calculations with and without dispersion corrections are performed and the effect of van der Waals forces on the interface properties is analyzed.…
A novel fluorescence immunoassay protocol, using high quantum yield of carbon dots as fluorescent labels, was developed for rapid quantitative determination of the model analyte human immunoglobulin G.
GO was incorporated in the collagen and fibrin composite film (CFGO), these films were used as wound dressing material on the experimental wounds of rats and the efficacy of CFGO was studied using conventional methods (schematic illustration).
Five Cd( ii ) coordination polymers based on 2,3′,5,5′-biphenyltetracarboxylic acid and different bis(imidazole) ligands have been synthesized.
In this paper, Fe-doped SrTiO 3 (FSTO) photocatalysts were successfully prepared via a facile solvothermal method, and their photocatalytic activities for degrading tetracycline (TC) under visible light irradiation were examined.
We report a high performance indium-gallium-zinc oxide (IGZO)/IGZO:Ti bilayer metal–oxide thin-film transistor (TFT) with a low drive voltage of${<}{\rm 2}~{\rm V}$. Compared with conventional IGZO TFTs, the novel bilayer metal–oxide TFTs through IGZO thickness modulation can reach the lowest off current of$1.6\times…
The pyridine adduct of a cadmium piperidine dithiocarbamate complex was used to deposit CdS thin films and for the synthesis of CdS nanoparticles.
There are many articles in the literature dealing with the first-order and the second-order differential subordination and superordination problems for analytic functions in the unit disk, but only a few articles are dealing with the above problems in the third-order case (see, e.g., Antonino and Miller (2011) and Pon…
Two typical shape-selective HZSM-5 catalysts were prepared by silica deposition and La2O3 loading, respectively. They were characterized by means of XRD, BET, NH3-TPD and Py-IR and were tested by alkylation of toluene with methanol. The deactivation mechanism of these catalysts in the alkylation was studied in detail…
We report the binding of milk β-lactoglobulin (β-LG) with PEG-3000, PEG-6000 and methoxypoly(ethylene glycol) anthracene (mPEG-anthracene) in aqueous solution at pH 7.4, using multiple spectroscopic methods, thermodynamic analysis, transmission electron microscopy (TEM) and molecular modeling.
A green approach for the preparation of water-dispersible functionalized graphene via one-step electrochemical exfoliation of graphite using 7,7,8,8-tetracyanoquinodimethane (TCNQ) anions as surface modifiers and electrolytes was described. TCNQ is an organic charge-transfer complex with electron accepting and notewor…
Si nanoparticles are coated with nitrogen-doped graphene-like nanosheets by a facile one-step carbon-thermal method, and the coated Si anode displays high initial coulombic efficiency.
Photothermal therapy (PTT) is an emerging technique for effective cancer elimination in animal experiments. The key to the success of the PTT is to develop efficient and safe photosensitive agents. Activated carbon (AC), a widespread material safely used in routine and emergent medical services, is emerging as a nasce…
Various transition metal oxide-based nanostructures with outstanding lithium-ion storage properties are considered as the most appealing candidates to substitute conventional carbonaceous anode materials in lithium-ion batteries. However, the rational design and tailored synthesis of hybrid materials with specific com…
We demonstrate the formation of oxime-functional macromolecular stars that are able to dissociate and reconstruct themselves upon application of a stimulus.
A granular material exposed to shear shows a variety of unique phenomena: Reynolds dilatancy, positional order and orientational order effects may compete in the shear zone. We study granular packing consisting of macroscopic prolate, oblate and spherical grains and compare their behaviour. X-ray tomography is used to…
Diabetes mellitus is a chronic condition resulting from insufficient β-cell mass, which leads to improper glycemia regulation. Research efforts have focused on expanding islets and β-cells in vitro for use in cell-based therapies to cure diabetes. Collagens are triple-helix extracellular matrix proteins with widesprea…
