Two new dysprosium(iii) complexes, [Dy(2)(HL(1))(4)(CO(3))]·4H(2)O (1) and [Dy(2)(L(2))(2)(NO(3))(2)(CH(3)OH)(2)]·4CH(3)CN (2), have been synthesized from the Schiff-base ligands N'-((2-hydroxy-1-naphthyl)methylene)benzohydrazide (H(2)L(1)) and N'-((2-hydroxy-1-naphthyl)methylene) picolinohydrazide (H(2)L(2)). Single-…
Because it is impossible to realize broadband-type, red-light-emitting phosphors in the oxide composition pool, both pure nitrides and oxynitrides have been considered as potential red phosphors for use in light emitting diode (LED) applications. However, only a limited number of red phosphors have been discovered. Fo…
Dispersible silica nanoparticles as carrier for enhanced bioactivity of chlorfenapyr 259
We incorporated a near-infrared (NIR) fluorescent dye, indocyanine green (ICG), in amine-modified layered double hydroxide nanoparticles (LDHs) by electrostatic attractions to render LDHs–ICG as an efficient NIR contrast agent for in vivo optical imaging. The further coating of chitosan on the external surfaces of LDH…
Two terbium ions in a triple-decker complex (Pc)Tb(Pc)Tb(T(p-OMe)PP) (Pc = phthalocyaninato, T(p-OMe)PP = tetra-p-methoxyphenylporphyrinato) have shown sharply different magnetic behaviours depending on symmetry of the coordination polyhedron. The fast quantum tunnelling relaxation process in a square-prismatic site h…
A glucose-responsive controlled-release system based on the competitive combination between glucose oxidase, glucosamine and glucose has been described, which exhibits perfect controlled release properties and high selectivity for glucose over other monosaccharides. This paved the way for a new generation of stimuli-r…
Increasing efforts have been made to fabricate Au/graphene composites due to the fascinating properties of both graphene and gold. Some Au nanoparticles with an average size of tens of nanometers were directly deposited on reduced graphene oxide (RGO), utilizing the residual oxy-functional groups as the “hitching post…
Daunorubicin (DNR) has a broad spectrum of anticancer activity, but is limited in clinical application due to its serious side effects. The aim of this study was to explore a novel "smart" pH-responsive drug delivery system (DDS) based on titanium dioxide (TiO(2)) nanoparticles for its potential in enabling more intel…
Metal-free catalysts are essential for various chemical reactions in industrial chemistry. Amino-functionalized carbon is a cheap and environmentally friendly solid basic catalyst. Here, NEt3-graphene solid basic catalyst has been synthesized through a consecutive deprotonation/carbometalation and electrophilic substi…
An efficient red luminophor (TTPEBTTD) consisting of a 4,7-di(thiophen-2-yl)benzo-2,1,3-thiadiazole core and tetraphenylethene peripheries is developed. The non-doped electroluminescence device based on TTPEBTTD radiates red light with high efficiency up to 3.7%. The nanoparticles of TTPEBTTD are promising fluorescent…
Herein we demonstrate the realization of a new technological concept, which enables the use of shape memory polymers (SMPs) as switchable information carriers. At first, we applied a surface-specific dyeing process based on ‘guest-diffusion’ on two sophisticated polymeric host materials, including a thermoplastic poly…
Macroporous, low-cost and recyclable kitchen sponges are explored as effective electrode platforms for supercapacitor devices. A simple and scalable process has been developed to fabricate MnO2–carbon nanotube (CNT)–sponge supercapacitor electrodes using ordinary kitchen sponges. Two organic electrolytes (1 M of tetra…
A novel high efficiency red emitting Sr 2 MgAl 22 O 36 :Mn 4+ phosphor is synthesized by solid-state reaction method. The optimized red emitting Sr 2 MgAl 22 O 36 :Mn 4+ phosphor exhibits high quantum efficiency (QE) of ∼80%, fluorescence lifetime of ∼1.25 ms and the Commission International de I’Eclairage (CIE) chrom…
Benzene-fused bis-(borondipyrromethene)s (bis-BODIPYs) were synthesized by retro-Diels-Alder reaction of the corresponding bicyclo[2.2.2]octadiene-fused (BCOD-fused) bis-BODIPYs, which were, in turn, prepared from 4,8-ethano-4,8-dihydropyrrolo[3,4-f]isoindole derivatives. The π-fused bis-BODIPY chromophores were desig…
ZnO hollow nanosphere (HNS) arrays decorated with Ag nanoparticles (NPs) were fabricated on silicon substrates using self-assembled monolayer polystyrene (PS) nanospheres as the template. The O2 plasma etching was introduced to manipulate the diameters of the ZnO HNSs. This fabrication method has the advantages of sim…
In this feature article we will critically discuss the synthesis and characterisation aspects of Ln(3+)-doped nanoparticles (NPs) that show upconversion, upon 980 nm excitation. Upconversion is a non-linear process that converts two or more low-energy photons, often near-infrared photons, into one of higher energy, e.…
Porous polyaniline–camphorsulfonic acid (PANI–CSA) counter-electrodes (CEs) for dye-sensitized solar cells (DSSCs) were fabricated by secondary doping-based polymerization with different porogen decomposition. The average pore diameter was ca. 50 and 150 nm for BPO and AIBN, respectively. The increased Brunauer–Emmett…
Manganese dioxide/polyaniline coaxial nanowire networks are prepared by using double surfactant approach. This approach improves the interaction between the two active materials which has been confirmed by FTIR and XPS measurements, and yields a controllable uniform thin coating of polyaniline on the well-dispersed ma…
We report a simple, ultra-sensitive, and straightforward method for non-labeling detection of a cancer biomarker, using Rayleigh light scattering spectroscopy of the individual nanosensor based on antibody-antigen recognition and localized surface plasmon resonance (LSPR) λ(max) shifts. By experimentally measuring the…
Co-crystallisation of two components into one crystal form can enhance the solid-state properties of drug compounds. A plethora of crystallisation methods has been applied to co-crystallisation and the reported study compares the three most common ones (crystallisation from the melt, from solution and solvent-drop gri…
