In this paper, the ice nucleation temperatures of 10 μL water droplets on a series of sol-gel coatings with different roughness and surface energies were obtained using a customized automatic measurement system. Classical nucleation theory was then employed to explain the different icing behaviour on the coatings. It…
Oxygen reduction reaction (ORR) is investigated on bulk PdO-based catalysts (oxides of Pd and Pd3Co) in oxygen-saturated 0.1 M HClO4 to establish the role of surface oxides and adsorbed hydrogen in the activity and product selectivity (H2O/H2O2). The initial voltammetric features suggest that the oxides are inactive t…
Two 3D fluorescent Zn-MOFs solvothermally synthesized by a temperature-modulated method exhibit rapid and discriminative detection of nitro aromatic compounds with high sensitivity.
Triptycene based and 1,2,3-triazole linked microporous polymers (SA BET up to 1348 m 2 g −1 ) have been synthesized. High CO 2 uptake (up to 4.45 mmol g −1 ) and CO 2 /N 2 selectivity (up to 48 at 273 K) were observed.
nanotubular (TNT) surface structure, (ii) the self-polymerization of dopamine on TNT and the reduction of Ag and (iii) the modification of the Ag nanoparticles using polydopamine and further being immersed in SBF for the biomimetic mineralization of CaP. The surface morphology and microstructure of this novel coating…
A graphene-polydopamine hybrid was prepared and decorated with ultrafine Pd nanoparticles to give a stable catalyst that disperses well in polar solvents. Its catalytic activity was investigated in the reduction of 4-nitrophenol, K 3 [Fe(CN) 6 ], methylene blue and rhodamine B.
The reciprocal hybridization of MoO2 nanoparticles and few-layer MoS2 has been realized via a facile hydrothermal reaction. The resulting MoO2/MoS2 hybrids exhibit a high reversible specific capacity of 1103 mA h g(-1) at 0.2 A g(-1) with a high rate performance (273 mA h g(-1) at 6.4 A g(-1)) and an excellent cycling…
Phenyl sulfonic acid functionalized mesoporous SBA-15 silica was prepared through the silanization of activated mesoporous SBA-15 with diphenyldichlorosilane followed by silylation and sulfonation.
A facile one-pot route was developed to obtain organic nanoparticles for fabrication of microporous POFs which can be utilized to entrap Ag nanoparticles and show excellent catalytic performance for organic dyes such as methylene blue in water.
In the field of dye-sensitized solar cells, polymer electrolytes are among the most studied materials due to their ability to ensure both high efficiency and stability, the latter being a critical point of these devices. Hundreds of polymeric matrices have been proposed over the years, and their functionalization with…
A series of well-designed highly branched PEG-catechol based thermo-responsive copolymers were synthesized via a one-pot RAFT polymerization. A varying degree of photocrosslinkable (meth)acrylate moieties were incorporated within the 3D structure to allow on-demand photocuring (strong cohesion, unlike conventional PEG…
Easy shaping of chitosan (CS) as self-standing microspheres and functionalisation of its amino groups afford heterogeneous Pd-supported catalysts for Sonogashira cross-coupling.
New biocomposite, porous graphene–soy protein (GS) aerogels were prepared by a simple hydrothermal method and the mechanism of ciprofloxacin adsorption onto them was investigated.
This is the first report showing that the superlubricity of silicone oil with an ultra-low friction coefficient of 0.004 (one-thirtieth of its original value) can be achieved between two surfaces (Si 3 N 4 /glass) after running-in with an acid solution.
Excess reactive oxygen species (ROS) have been proved to damage cancer cells efficiently. ROS overproduction is thus greatly desirable for cancer therapy. To date, ROS production is generally uncontrollable and outside cells, which always bring severe side-effects in the vasculature. Since most ROS share a very short…
Here we report the synthesis of Nb 2 O 5 /graphene nanocomposites, through a simple hydrothermal method, with Nb 2 O 5 nanoparticles anchored on reduced graphene oxide sheets.
Research on organic semiconductor thin films has been accelerated due to their potential for low cost and large area flexible devices.
Recently, it has been found that moxifloxacin, an antibiotic drug, promotes wound healing without induction to bacterial resistance.
A benzothiazole derived chemosensor L has been designed based on the excited-state intramolecular proton transfer (ESIPT) mechanism to afford a fluorescence turn-on response specifically in the presence of Hg(2+) ions over a host of biologically relevant metal ions as well as toxic heavy metal ions. The chemosensor ex…
