Biofunctionalized surface-modified silver nanoparticles for gene delivery
Silver nanoparticles (AgNPs) find use in different biomedical applications including wound healing and cancer. We propose that the efficacy of the nanoparticles can be further augmented by using these particles for gene delivery applications. The objective of this work was to engineer biofunctionalized stable AgNPs wi…
Full-color tunable mechanofluorochromism and excitation-dependent emissions of single-arm extended tetraphenylethylenes
Single-arm extended tetraphenylethylene derivatives exhibit full-color tunable mechanofluorochromism and excitation-dependent emissions.
Tuning nonlinear optical absorption properties of WS 2 nanosheets
To control the optical properties of two-dimensional (2D) materials is a long-standing goal, being of both fundamental and technological significance. Tuning nonlinear optical absorption (NOA) properties of 2D transition metal dichalcogenides in a cost effective way has emerged as an important research topic because o…
Mapping water uptake in organic coatings using AFM-IR
The long-term failure of seemingly intact corrosion resistant organic coatings is thought to occur via the development of ionic transport channels, which spontaneously evolve from hydrophilic regions on immersion, i.e., as a result of localized water uptake. To this end, we investigate water uptake characteristics for…
Galactose-functionalized multi-responsive nanogels for hepatoma-targeted drug delivery
We report here a hepatoma-targeting multi-responsive biodegradable crosslinked nanogel, poly(6-O-vinyladipoyl-D-galactose-ss-N-vinylcaprolactam-ss-methacrylic acid) P(ODGal-VCL-MAA), using a combination of enzymatic transesterification and emulsion copolymerization for intracellular drug delivery. The nanogel exhibite…

A novel soft-matter composite film of ethylene-vinyl acetate and liquid crystal with an energy conservation efficiency of 40.4% is developed.
Platinum nanoparticles supported on N-doped carbon nanotubes for the selective oxidation of glycerol to glyceric acid in a base-free aqueous solution
Pt/N-CNT out-performed Pt/CNT for glycerol oxidation with molecular oxygen under atmospheric pressure in a base-free aqueous solution, in terms of glycerol conversion and glyceric acid selectivity.
Solid-state, high-performance supercapacitor using graphene nanoribbons embedded with zinc manganite
Flexible supercapacitor fabricated from ZnMn 2 O 4 /GNR demonstrate high performance in terms of energy density 37 W h kg −1 and power density 30 kW kg −1 with robust mechanical strength under harsh conditions.
(100) surface-exposed CeO 2 nanocubes as an efficient heterogeneous catalyst in the tandem oxidation of benzyl alcohol, para-chlorobenzyl alcohol and toluene to the corresponding aldehydes selectively
Efficient oxidation of aromatic alcohols and toluene to the corresponding aldehydes was achieved selectively by an active-surface-exposed CeO 2 nanocube heterogeneous catalyst.
Influence of solvent on crystal nucleation of risperidone
Over 2100 induction time experiments were carried out for the medium-sized, antipsychotic drug molecule, risperidone in seven different organic solvents. To reach the same induction time the required driving force increases in the order: cumene, toluene, acetone, ethyl acetate, methanol, propanol, and butanol, which r…
Tunable ferromagnetic ordering in MoS 2 nanosheets with fluorine adsorption
Two-dimensional ferromagnetic ultrathin nanosheets hold great promise for next generation electronics and spintronics. Here, intrinsic ferromagnetism was achieved through a new effective strategy by fluorine adsorption on MoS2 nanosheets, where the fluorinated MoS2 nanosheets exhibit stable ferromagnetic hysteresis at…

Stretching of collapsed polymers causes an enhanced dissipative response of PNIPAM brushes near their LCST
Poly(N-isopropyl acrylamide) (PNIPAM) is a stimulus-responsive polymer that can switch in water from an expanded state below the lower critical solution temperature (LCST) of 32 °C to a globular state above the LCST. It was recently shown that, as a consequence of this conformational transition, the interfacial and (t…
