Layered V2O5 hydrate has been applied as the hole transport layer (HTL) in organic solar cells (OSCs). V2O5 is obtained from a sodium metavanadate solution in water under ambient conditions, resulting in a final thin film of formula V2O5·0.5H2O. The 0.5 water molecules are not removed from the V2O5 layered structure u…
The temperature dependent morphological evolution and its effect on the electrochemical supercapacitive properties of Ni(OH)2 thin films have been systematically investigated. A temperature dependent growth mechanism model is proposed for the changes in microstructure. Different nanostructures of Ni(OH)2 thin films su…
A facile DNA delivery method would greatly facilitate studies of plant functional genomics. However, plant cell walls limit the utilization of nanoparticles on plant research. Here, we employed functionalized mesoporous silica nanoparticles (MSNs) to develop a MSN-mediated plant transient gene expression system. In th…
In this work, a heteroatom-containing luminogen (TPE-Py) with multi-functionalities was synthesized in a reasonable yield by melding a pyridinium unit with tetraphenylethene through vinyl functionality. TPE-Py is weakly emissive in solution but becomes a strong emitter when aggregated as nanoparticle suspensions in po…
The combination of graphene with noble-metal nanostructures is currently being explored for strong light–graphene interactions enhanced by plasmons. We introduce a novel hybrid graphene–metal system for studying light–matter interactions with gold-void nanostructures exhibiting resonances in the visible range. Enhance…
We developed a new strategy, i.e., a seed-assisted method, to fabricate a three-dimensional (3D) SiO2@Fe3O4 core/shell nanorod array/graphene architecture. The fabrication processes involved deposition of β-FeOOH seeds on the graphene surfaces in the ferric nitrate aqueous solution, subsequent growth of β-FeOOH nanoro…
In this paper we provide a detailed convergence analysis for an unconditionally energy stable, second order accurate convex splitting scheme for the modified phase field crystal equation, a generalized damped wave equation for which the usual phase field crystal equation is a special degenerate case. The fully discret…
ZnO‐based transparent conductive thin films have attracted much attention as a promising substitute material to the currently used indium‐tin‐oxide thin films in transparent electrode applications. However, the detailed function of the dopants, acting on the electrical and optical properties of ZnO‐based transparent c…
A composite material has been successfully prepared for the first time using an amino-containing metal–organic framework (MOF) as a new type of host matrix material to anchor hemin and simulate the peptidic microenvironment of the native peroxidase. The material was characterized by XRD, SEM, EDS, FT-IR techniques and…
Highly charged hydrophilic superparamagnetic Fe3O4 colloidal nanocrystal clusters with an average diameter of 195 nm have been successfully synthesized using a modified one-step solvothermal method. Anionic polyelectrolyte poly(4-styrenesulfonic acid-co-maleic acid) sodium salt containing both sulfonate and carboxylat…
The recent development and implementation of new technologies have led to new era, the nano-revolution which unfolds role of plants in bio and green synthesis of nanoparticles which seem to have drawn quite an unequivocal attention with a view of synthesizing stable nanoparticles. Although nanoparticles can be synthes…
A facile method for the synthesis of Zn2Al-borate and Mg3Al-borate layered double hydroxides (LDHs) with extremely high specific surface areas of 458.6 and 263 m(2) g(-1) and containing delaminated nanosheets is reported. To the best of our knowledge, this is the first report of LDH powders that still remain exfoliate…
An environmentally benign and scalable route for the production of gram scale quantities of nitrogen-doped graphene using a downstream microwave plasma source is reported. Simultaneous reduction and doping of graphene oxide is achieved and the process negates the need for high temperatures and toxic solvents associate…
In this current work, a flaky nickel sulfide (Ni 3 S 2 ) nanostructure was deposited on a Ni foam substrate using a facile potentiodynamic deposition approach and investigated as an electroactive material for high-performance supercapacitor for the first time. X-ray diffraction, scanning electron microscopy and transm…
For practical use of supercapacitors, new electrode materials are needed with high ionic adsorption capacity at the solid–liquid interface, fast and reversible surface redox reaction, and fast charge transfer. In the current study, we produce a new hybrid material of electrochemical double layer capacitive graphene, p…
Ordered WO3 nanowire arrays on carbon cloth (WNCC) conductive substrates are successfully prepared by a facile hydrothermal method. The as-prepared samples were characterized by XRD, SEM and TEM and directly functionalized as supercapacitor (SC) and lithium-ion battery (LIB) electrodes without using any ancillary mate…
The use of an amino-pyridyl substituted β-diketone, N-(2-pyridyl)-ketoacetamide (paaH), has allowed for the isolation of two new families of isostructural mononuclear lanthanide complexes with general formulae: [Ln(paaH*)2(H2O)4][Cl]3·2H2O (Ln = Gd (1), Tb (2), Dy (3), Ho (4), Er (5) and Y (6)) and [Ln(paaH*)2(NO3)2(M…
Hierarchically porous manganese dioxide (MnO2) microspheres were fabricated by a facile hydrothermal method using potassium permanganate as the precursor at different hydrothermal temperatures.

Over the last twenty-five years 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) has made a significant impact on the field of diagnostic imaging. DOTA is not the only metal chelate in use in medical diagnostics, but it is the only one to significantly impact on all of the major imaging modalities Magne…
Among all the functional materials, ZnO plays an outstanding role in terms of chemical and physical properties, but also in terms of morphological variety and the number of reported synthesis approaches. Complex shapes and hierarchical architectures make ZnO a perfect example to study chemical and crystallization mech…
