Encapsulated phase change materials stabilized by modified graphene oxide
The microencapsulation of phase change materials (n-hexadecane) with double-walled shells (polystyrene/graphene oxide) was realized from Pickering emulsion templating. Graphene oxide nanosheets were modified by the polycondensate of diethanolamine and adipic acid, which can well stabilize oil-in-water (O/W) Pickering…
Quantum dots in diagnostics and detection: principles and paradigms
Quantum dots are semiconductor nanocrystals that exhibit exceptional optical and electrical behaviors not found in their bulk counterparts. Following seminal work in the development of water-soluble quantum dots in the late 1990's, researchers have sought to develop interesting and novel ways of exploiting the extraor…
Charge carrier mobility in organic molecular materials probed by electromagnetic waves
Charge carrier mobility is an essential parameter providing control over the performance of semiconductor devices fabricated using a variety of organic molecular materials. Recent design strategies toward molecular materials have been directed at the substitution of amorphous silicon-based semiconductors; accordingly,…

Direct synthesis of methane from CO 2 –H 2 O co-electrolysis in tubular solid oxide electrolysis cells
Methane is directly generated from CO 2 –H 2 O with a yield ratio of 41.0% using tubular units integrating electrolysis and methanation processes.
Advances in the environmental transmission electron microscope (ETEM) for nanoscale in situ studies of gas–solid interactions
Although available since the early days of electron microscopy, recent technology developments of the environmental transmission electron microscope (ETEM) have enabled new research in the study of nanomaterials in gaseous environments. Significant improvements in scanning/transmission electron microscope (S/TEM) tech…

N-doped CDs can be obtained directly with high yield by pyrolyzing ethanolamine in air within just 7 minutes with the assistance of hydrogen peroxide.
Multichromophoric electrochromic polymers: colour tuning of conjugated polymers through the side chain functionalization approach
Organic electrochromic materials have gained constantly increasing interest over the years with respect to their inorganic counterpart due to essentially two distinctive characteristics: their processability through solution based low cost processes and their wide colour palette. Such characteristic features enabled t…
One pot synthesis of monodisperse water soluble iron oxide nanocrystals with high values of the specific absorption rate
We report a highly reproducible route to synthesize iron oxide nanoparticles (IONPs) with control over size and shape and with size dispersions around 10%. By tuning the relative ratio of squalane to dibenzyl ether, which were used as solvents in the synthesis, the size of the particles could be varied from 14 to arou…
Direct validation of the restriction of intramolecular rotation hypothesis via the synthesis of novel ortho-methyl substituted tetraphenylethenes and their application in cell imaging
We demonstrate a novel synthetic approach to ortho-methyl substituted tetraphenylethene materials, which can be utilised for directly validating the restriction of intramolecular rotation hypothesis as the basic mechanism of aggregation-induced emission phenomenon and cell imaging.

Transition metal embedded g-C 3 N 4 sheets demonstrate promising multi usage in various fields such as memory devices, photocatalysis.
Preparation and Characterization of Biodegradable PLA/PCL Polymeric Blends
In this study, blends of biodegradable Poly (lactic acid) (PLA) and Polycaprolactone (PCL), were prepared using Hakee Rheomix and characterized for rheological, thermal, mechanical and viscoelastic properties. Morphology of tensile fractured surfaces was examined through scanning electron microscopy (SEM). The blends…
Photo-mechanical azobenzene cocrystals and in situ X-ray diffraction monitoring of their optically-induced crystal-to-crystal isomerisation
We demonstrate the first supramolecular cocrystallisation strategy for generating crystalline azobenzene materials with a range of photo-mechanical and thermochemical properties: from those that exhibit isomerisation without any change in crystal shape to those that undergo a crystal-to-crystal cis – trans isomerisati…
Dissecting the steps of CO 2 reduction: 1. The interaction of CO and CO 2 with γ-Al 2 O 3 : an in situ FTIR study
The adsorption of CO2 and CO was investigated on a pure γ-Al2O3 support material that has been used in Pd and Ru catalysts for the reduction of CO2. The adsorption of CO2 resulted in the formation of carbonates, bicarbonates and linearly adsorbed CO2 species. The amount and the nature of the adsorbed species were depe…
Enhanced up-conversion and temperature-sensing behaviour of Er 3+ and Yb 3+ co-doped Y 2 Ti 2 O 7 by incorporation of Li + ions
Y2Ti2O7:Er(3+)/Yb(3+) (EYYTO) phosphors co-doped with Li(+) ions were synthesized by a conventional solid-state ceramic method.

On the upconversion fluorescence in carbon nanodots and graphene quantum dots
Upconversion fluorescence has been frequently cited as an important feature in carbon nanodots (CNDs) and graphene quantum dots (GQDs); and some mechanisms and potential applications have been proposed. Contrary to such a general belief, we demonstrate in this report no observable upconversion fluorescence based on fi…
