Magnetic hybrid colloids (MHCs) decorated with different-sized Ag nanoparticles (Ag07@MHC, Ag15@MHC, and Ag30@MHC denote MHCs decorated with ∼7 nm, ∼15 nm, and ∼30 nm AgNPs, respectively) are synthesized and used to investigate their antimicrobial efficacy and mechanism. An MHC (diameter ∼ 0.6 μm) is a cluster of supe…
We report the fabrication of pH responsive switchable emulsions that quickly destabilise at acidic pH, but switch back to the stable state when the pH is neutralized. The pH triggered flocculation is further used to influence the assembly of droplets into predetermined shapes. Such systems, stabilised using natural an…
The aim of the present work was to assess the merits of supercritical CO2 (SC-CO2) as a process for protein encapsulation into calcium carbonate microparticles. Lysozyme, chosen as a model protein, was entrapped during CaCO3 precipitation in two different media: water (normal route) and SC-CO2. The particles were char…
A thermochromic magnetic ionic liquid containing a cationic iron(III) Schiff-base complex has been developed, whose color and magnetic moment change with temperature because of spin crossover in the liquid state. This spin-crossover behavior closely resembles that of a solid having the same cation.
A time-dependent three-dimensional (3D) impedance model of mixed ionic electronic conducting solid oxide fuel cell (SOFC) cathodes that considers the complex coupling of gas diffusion, surface exchange, ionic bulk-diffusion and electrolyte conductivity is presented. By using the finite element method, this model enabl…
Biopolymer hosts can be successfully used for the fabrication of multifunctional photonic devices due to their good optical properties, biocompatibility, remarkable mechanical properties and a wealth of chemical functionalization. Particularly, the silk fibroin (SF) biopolymer presents a wide range of suitable propert…
Superposed cobalt(II)-cobalt(III) layered double hydroxide (Co(II)-Co(III)-LDH) nanoplates were synthesized by an oil droplet template method, in which the main steps are as follows: LDH nanosheets were first assembled on an oil droplet template to form a multishell sphere, and then the oil droplet was easily removed…
There are significant challenges in assessing the fate and exposure of nanoparticles (NPs) in the environment owing to the lack of information on their use, potential pathways and sinks in the environment. In order to better understand the environmental exposure of silver nanoparticles (AgNPs), we reviewed the uses an…
Hybrid polyoxometalate-porphyrin copolymeric films were obtained by the electro-oxidation of zinc octaethylporphyrin (ZnOEP) in the presence of a Dawson type polyoxophosphovanadotungstate bearing two pyridyl groups (POM(py)2). The synthesis of a series of POM(py)2 consisting of [P2W15V3O62](9-) functionalized with dio…
A series of isomorphous 3D Co(II)(1-x)Ni(II)(x) MOFs based on ferromagnetic chains show SCM-type slow relaxation and the Co-rich system can exhibit a higher blocking temperature than both Co(II) and Ni(II) parent materials.
A small molecule, protein mimetic based approach is shown to specifically inhibit lipid catalysed self-assembly of islet amyloid polypeptide (IAPP). The lipid-bound oligomerization of this peptide is implicated in cellular dysfunction of insulin secreting β-cells in type II diabetes.
We report here a strategy that allows the preparation of a novel water-soluble polymeric prodrug, paclitaxel–poly(ethyl ethylene phosphate) conjugated with folic acid molecules (abbreviated as PTX–PEEP–FA). PTX was directly used as an initiator for the ring-opening polymerization (ROP) of 2-ethoxy-2-oxo-1,3,2-dioxapho…
Owing to its high application potential, the printed functional layers and devices on flexible substrates attract attention of many scientists, in the last few years. Very promising area is represented by so called printed conductive polymers (polyaniline, polythiophene or polypyrroles, etc.). Currently, the most wide…
A new functional dilactone, 3-(2-propynyl)-1,4-dioxane-2,5-dione (4), was synthesized from ethyl glyoxalate and propargyl bromide via a 4-step reaction sequence. Ring-opening (co)polymerisation of the alkyne-functionalised monomer 4 with L-lactide was carried out in dichloromethane at 30 °C using N,N-dimethylaminopyri…
Researchers are in constant pursuit of solid-state emitters with high emission efficiency, excellent photostability and large Stokes shift. Among them, siloles are good representatives. In this paper, we report the effect of substituent on the emission of silole. 1,1,3,4-Tetraphenylsilole (TPS) is weakly emissive at 3…
In this paper, we systematically studied the effects of coronene as nucleation seeds for graphene synthesis at low temperatures by chemical vapor deposition. Naphthalene was used as a solid carbon source which is capable of producing graphene at temperatures down to 300 °C. The experimental results showed clear eviden…
A rational design has resulted in the large-scale synthesis of amorphous carbon coated mesoporous NiO (denoted as NiO@C) nanocomposites through a hydrothermal method. The mesoporous characteristics of as-synthesized NiO@C nanocomposites provide an ultrahigh active surface area and thus significantly enhance the interc…
A facile synthesis route is reported for preparation of N-doped mesoporous ZnO nanospheres by a solvothermal treatment of Zn(NO3)2·6H2O which provides a source of both zinc and nitrogen. A variety of different spectroscopic and analytical techniques, such as powder X-ray diffraction (XRD), transmission electron micros…

A series of novel silicon(IV) phthalocyanines conjugated axially with different nucleoside moieties (uridine, 5-methyluridine, cytidine, and 5-N-cytidine derivatives) have been synthesized and evaluated for their photodynamic activities. The uridine-containing compound 1 exhibits the highest photocytotoxicity against…
