The midblock composition of poly(lactide)- block -poly(ε-caprolactone- co -ε-decalactone)- block -poly(lactide) is used to tune block polymer melting point, crystallinity, segregation strength and tensile properties.
CoFe 2 O 4 –SiO 2 –TiO 2 core–shell–shell magnetic nanocomposites have been prepared by coating cobalt ferrite nanoparticles with double layers of SiO 2 –TiO 2 .
Poly(2-oxazoline)s are emerging revolutionary biomaterials, exhibiting comparable and even superior properties to well-established counterparts. Overcoming current tedious wet synthesis methods, we report solvent-free and substrate independent, plasma polymerised nanoscale biocompatible polyoxazoline coatings capable…
A low molecular weight hydrogelator with a covalently appended imidazole moiety is reported. Capable of percolating water in the pH range of 6 to 8, it proves to be an efficient catalyst upon self-assembly, showing Michaelis-Menten type kinetics. Activities at different pH values correlated with dramatic structural ch…
In aqueous dispersions of graphene quantum dots (GQDs), aniline is in situ polymerized to produce polyaniline-GQDs hybrids and dye-sensitized solar cells fabricated with the hybrids indicate highest power conversion efficiency of 3.12%.
Herein, we report a comprehensive and comparative study on the crystal structure, and microstructural, optical, magnetic, hyperfine and electrochemical properties of Fe3O4 microspheres (S1) of diameter ∼418 nm and Fe3O4@SiO2 core-shell microspheres (S2) of diameter ∼570 nm. Each asymmetric unit of the crystalline Fe3O…
Recently, development of carbon nanocomposites composed of carbon nanostructures and metal nanoparticles has attracted much interests because of their large potential for technological applications such as catalyst, sensor, biomedicine, and disinfection. In this work, we established a simple chemistry method to synthe…
This paper reviews recent years’ (2009–2015) advances in graphene/PA6 nanocomposites for the first time.
First-principles density functional theory (DFT) calculations were carried out to investigate the structural and electronic properties of beryllium (Be) doped and, Be with boron (B) co-doped graphene systems.
The self-assembly behaviour of the eight stereoisomers of Val-Phe-Phe tripeptides under physiological conditions is assessed by several spectroscopy and microscopy techniques. We report the first examples of self-organised hydrogels from tripeptides in the l-d-l or d-l-d configuration, besides the expected gels with t…
The rational design of monodisperse ferroelectric nanocrystals with controlled size and shape and their organization into hierarchical structures has been a critical step for understanding the polar ordering in nanoscale ferroelectrics, as well as the design of nanocrystal-based functional materials which harness the…
In this paper, hierarchical SnO 2 @MO x (SnO 2 @NiO, SnO 2 @Co 3 O 4 , SnO 2 @MnO 2 ) heterostructures grown on carbon cloth (CC) for high performance supercapacitors are fabricated by a two-step solution-based method.
-stilbene, the molecular conformation in the single crystal and the tetracene backbone should contribute to the unique photo behavior. In particular, the fast responsive, photo-reversible and thermo-irreversible photochromic effect facilitated in the solid state opens a new field of aggregation-promoted photochromism.
Waste pulp residues are herein exploited for the synthesis of a sorbent for humic acid (HA), which is a major water pollutant. Cellulose pulp was etherified with a quaternary ammonium salt in water thereby introducing positive charges onto the surface of the pulp fibers, and subsequently mechanically disintegrated int…
Due to the vibration of the phenazine unit, compound S1 exhibits dual fluorescence in solution but one peak in the solid state. Based on this novel phenomenon and combined with the intramolecular energy transfer (IET) effect, a colour-tunable luminescence, even near white emission from a single molecule could be achie…
Heteroatom induced differences in mechanochromism and acidochromism of anthracene based fluorophores are described.
Two-dimensional (2D) layered transition metal dichalcogenide (TMD) materials (e.g., MoS2) have attracted considerable interest due to their atomically thin geometry and semiconducting electronic properties. With ultrahigh surface to volume ratio, the electronic properties of these atomically thin semiconductors can be…
A high-order and energy stable scheme is developed to simulate phase-field models by combining the semi-implicit spectral deferred correction (SDC) method and the energy stable convex splitting technique. The convex splitting scheme we use here is a linear unconditionally stable method but is only of first-order accur…
The partial replacement of Sr by Ca in PrBa 0.5 Sr 0.5 Co 2 O 5+δ layered perovskite provides a breakthrough for achieving reliable operation of high performance IT-SOFCs.
The kinetics of reaction and the local atomic structure of carbonating C–S–H gel are characterised using high-energy synchrotron radiation.
