The photo-controlled shift of pH titration curves, describing the acidochromic behaviour of a spiropyran switch network, was harnessed for the realisation of a molecular triode. The intricate network can be correctly interpreted with respect to the pH dependence of the main involved species.
The formation of hybrid nanostructures improves the barrier properties significantly by increasing the path of diffusion of the permeant.
Decoration of silicate nanodisks with a pH-sensitive polymer allows for the effective delivery of an anticancer drug in cancer cells with high efficacy.
Due to their high mechanical and transport properties, graphene-derived materials have aroused a great deal of interest in the most varied sectors. Among these, graphene nanoplatelets have been gaining interest due to the fact they can be synthesized in a way scalable to mass production, enabling them to be considered…
[Sm(hfac)3(boaDTDA)]n is the first coordination compound of a thiazyl-based neutral radical ligand to exhibit ferromagnetic ordering; TC = 3 K. The [Sm(iii)-radical]n species is soluble in common organic solvents and can be sublimed quantitatively. A McConnell I mechanism is implicated in local exchange pathways that…
A series of self-assembled mixed micelles composed of TPGS and Pluronics were fabricated and their cellular uptake and exocytosis behaviors were studied in 2D cell and 3D tumor spheroid models. Together with in vivo efficacy studies, our results demonstrate that TPGS is not only critical to stabilize the mixed micelle…
An analytical solution of a mathematical model is reported to explain the growth kinetics of gold nanorods grown <italic>via</italic> seed mediated synthesis.
A 12-mer peptide with an affinity for the meso diad sequence of poly(N-isopropylacrylamide) (PNIPAM) was identified through affinity-based peptide screening. A model protein (i.e., human serum albumin (HSA)) chemically modified with the peptide was successfully precipitated with PNIPAM above the lower critical solutio…
A range of particulate poly(ether ketone ketone)s (PEKKs) have been synthesised by a room temperature Friedel–Crafts dispersion polymerisation.
over 24 h under physiological conditions (37 °C, pH 7.4 phosphate buffered saline). Extracts obtained from both the thiolated and S-nitrosated polymers were not found to significantly impair the viability of human dermal fibroblasts or induce morphological changes, indicating that this cysteine-based polyphosphazene m…
Elastomeric gum polyurethane nanocomposites were synthesised.
The development of inherently conducting polymers as controllable/programmable drug delivery systems has attracted significant interest in medical bionics, and the interfacial properties of the polymers, in particular, protein adsorption characteristics, is integral to the stability of the overall performance. Herein…
During cooling, considerable changes such as wrinkle formation and edge passivation occur in graphene synthesized on the Cu substrate. Wrinkle formation is caused by the difference in the thermal expansion coefficients of graphene and its substrate. This work emphasizes the cooling-induced edge passivation. The graphe…
A single superabsorbent for separating both layered and emulsified oil/water mixtures designed by gamma radiation assisted grafting in aqueous ethanol solution.
The bridging nature of in situ generated hydroxide ions and carboxylates (RCOO(-); R = CH3, C2H5, CH2Ph) has been utilized to design a new family of [Cu6] coordination complexes: [Cu6(μ3-OH)2(μ-H2L)2(μ1,1,3-O2CCH3)2(μ1,3-O2CCH3)2(μ-ClO4)2](ClO4)2·H2O (), [Cu6(μ3-OH)2(μ-H2L)2(μ1,1,3-O2CC2H5)4(μ-ClO4)2](ClO4)2·2H2O () a…
Semiconductor quantum dots (QDs) are very important fluorescent nanocrystals with excellent optical properties. However, QDs, at the single-particle level, show severe fluorescence intermittency (or blinking) on a wide time scale from milliseconds to minutes, which limits certain optical and biological applications. G…
The preparation of rod-like nitrogen-doped ordered mesoporous carbons (NOMCs) through a facial aqueous soft-template self-assembly route in one-pot is presented in this work.
Two ethylene-octene copolymers with 17 and 45 wt.% of octene (EOC-17 and EOC-45) were compared in nanocomposites with Cloisite 93A. EOC-45 nanocomposites have a higher elongation at break. Dynamical mechanical analysis (DMA) showed a decrease of<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mrow…
A novel synthesis of hierarchically porous, flow-through carbon/silica composite monoliths with ultra-high surface areas (~2600 m <sup>2</sup> g <sup>−1</sup> ), tunable porosity in micro/meso/macro-structured domains, and <italic>in situ</italic> growth of silver nanoparticles has been shown for catalytic use.
The study of perovskites has been active for a long time. Here, we rationally designed and prepared a double perovskite, LaBaZnSbO6, by selecting Zn(2+) and Sb(5+) with large size and charge differences, and, indeed, complete B-site ordering can be achieved. Careful study using powder X-ray diffraction data pinpointed…
