Two azobenzene α-cyclodextrin based nanovalves are designed, synthesized and assembled on mesoporous silica nanoparticles. Under aqueous conditions, the cyclodextrin cap is tightly bound to the azobenzene moiety and capable of holding back loaded cargo molecules. Upon irradiation with a near-UV light laser, trans to c…
A simple, low cost, and green method was developed for the synthesis of water-soluble and well-dispersed fluorescent carbon nanodots (CDs) via a one-step hydrothermal treatment of potatoes. The as-prepared CDs exhibit a strong blue fluorescence, with a quantum yield of up to 15%. We further explored the use of these C…
Schottky barriers formed by graphene (monolayer, bilayer, and multilayer) on 2D layered semiconductor tungsten disulfide (WS2) nanosheets are explored for solar energy harvesting. The characteristics of the graphene-WS2 Schottky junction vary significantly with the number of graphene layers on WS2, resulting in differ…
Printed electrochromic flexible films were obtained by combining transparent silver grid electrodes formed by self-assembly and inkjet printed WO3 nanoparticles. Concentrated dispersions of WO3 nanoparticles were inkjet printed on transparent plastic silver grid electrodes with a high transparency of 83% in the spectr…
The aim of this review is to provide an in-depth overview on the use of inorganic nano-sized entities for the generation of nanocomposite materials in the form of films and coatings for food packaging applications. According to recent trends toward “green” strategies, special focus has been dedicated to the developmen…
New classes of nanoporous organic polymers based on 1,3,5-triazine units (NOP-1–6) were synthesized via a straightforward, methane-sulfonic acid-catalysed, cost-effective Friedel–Crafts reaction of 2,4,6-trichloro-1,3,5-triazine and tetrahedral building blocks. Among them, NOP-3 with a Brunauer–Emmet–Teller (BET) spec…
Graphene oxide (GO) as a template for the morphology controllable synthesis of inorganic particles has recently attracted enormous attention. In this study, we report the synthesis of graphene/Ni–Al layered double hydroxide (LDH) nanowires by using GO and adjusting the loading of urea in hydrothermal reactions. Transm…
In this paper, we demonstrate a series of metal-free and inexpensive TiO2/carbon dot (CD) nanocomposites via facile hydrothermal synthesis from bidentate complexes of a green carbon source, vitamin C (VC). Other than the importance of deriving CDs from alternate carbon materials instead of graphitic precursors, the in…
Colloidal liquids interacting with short range attraction and long range repulsion, such as proposed for some protein solutions, have been found to exhibit novel states consisting of equilibrium particle clusters. Monte Carlo simulations are performed for two physically meaningful inter-particle potentials across a br…
Article Characterization of fibrillated celluloses. A short review and evaluation of characteristics with a combination of methods was published on January 1, 2014 in the journal Nordic Pulp & Paper Research Journal (volume 29, issue 1).
Native silk features strong, extensible and tough properties which originate from its hierarchical nanofibril structure. In the present study, native silk nanofibrils were obtained by dissolving degummed silk in salt–formic acid (FA), such as CaCl2–FA. The CaCl2–FA dissolved silk by breaking hydrogen bonds in the crys…
The CVD process for the spinning of carbon nanotube (CNT) fibres combines the nucleation, growth and aggregation of CNTs in the form of an aerogel with fibre spinning into a single process step. The optimisation of the process requires agility in multi-dimensional parameter space, so one tends to find parameter 'islan…
MnO 2 doped Fe 2 O 3 hollow nanofibers were successfully synthesized by the electrospinning method, which exhibit superior catalytic activity for low temperature NH 3 -SCR.

The exciton dynamics in monolayer and bulk MoSe2 samples are studied by transient absorption microscopy with a high spatiotemporal resolution. Excitons are injected with a point-like spatial distribution using a tightly focused femtosecond pulse. The spatiotemporal dynamics of these excitons are monitored by measuring…
Zinc oxide (ZnO) nanostructured materials have received significant attention because of their unique physicochemical and electronic properties. In particular, the functional properties of ZnO are strongly dependent on its morphology and defect structure, particularly for a semiconductor ZnO-based photocatalyst. Here,…
First-principles methods demonstrate the presence of facile oxygen vacancy formation at surfaces of α-MnO 2 , important to its good catalytic activity.
Pb substitution on anionic site of Mg 3 Sb 2 structure enhances the power factor and simultaneously reduces the thermal conductivity which leads to a ZT ≈ 0.84 at 773 K for Mg 3 Sb 1.8 Pb 0.2 alloy. The enhanced ZT of this system is comparable to bismuth telluride and selenide industrial materials which are toxic and…
Nowadays, advanced plant fiber reinforced composites have captured the attention of many important manufacturing sectors such as the construction, automotive, and packaging industries. Recently, Jute fiber reinforced composites have replaced the most widely used synthetic fiber (glass, kevlar) reinforced composites in…
, which becomes more relevant as particle size decreases and the ratio of surface area to volume increases. Given its biopersistence and resulting increased toxicity with time, there is a risk that long-term exposure to low nanoceria levels may eventually lead to adverse health effects. This critical review provides r…
