Research on energy storage devices has created a niche owing to the ever increasing demand for alternative energy production and its efficient utilisation. Here, a novel composite of Fe3O4 nanospheres and carbon quantum dots (C-dots) have been synthesized by a two step chemical route. Hybrids of C-dots with metal oxid…
Abstract There has been a great deal of attention and research devoted on nanoparticels (NPs) over the last 10 years. From current knowledge in the field of nanotoxicology, it has become evident that the most NPs, if not all are more toxic than bulk materials. The rapid progress and developing has been leading to conc…
ZnFe 2 O 4 microspheres, assembled by many primary nanocrystals, have been fabricated via a facile and cost-effective solvothermal approach and applied as pseudocapacitor electrode material.
The availability of S − groups with varying volume and pH of diastase tunes the size of AuNPs.
As an intrinsic thermally anisotropic material, the thermal properties of phosphorene must vary with respect to the crystal chirality. Nevertheless, previous studies of heat transfer in phosphorene have been limited to the 0.0° (zigzag, ZZ) and 90.0° (armchair, AC) chiralities. In this study, we investigate the orient…
The thermoelectric properties of two-dimensional graphyne sheets are investigated by using first-principles calculations and the Boltzmann transport equation method. The electronic structure indicates a semiconducting phase for graphyne, compared with the metallic phase of graphene. Consequently, the obtained Seebeck…
An organometallic Au13 cluster having two σ-bonded acetylide ligands was synthesized and its structure was determined by X-ray crystallography. Absorption spectral studies indicated the presence of electronic coupling between the superatomic Au13 core and the acetylide π-orbitals, which was supported by theoretical co…
Recently, two-dimensional materials such as molybdenum disulfide (MoS2) have been extensively studied as channel materials for field effect transistors (FETs) because MoS2 has outstanding electrical properties such as a low subthreshold swing value, a high on/off ratio, and good carrier mobility. In this study, we cha…
Novel enzyme-responsive emamectin benzoate microcapsules with remarkable loading ability and photo- and thermal stability were prepared for sustained crop protection.
A nickel oxide (NiO) electrode has been synthesized electrochemically, which is envisaged for supercapacitor application.
An aligned carbon nanotube/MoS 2 nanosheet hybrid fiber with remarkable electrochemical properties is synthesized. It is used to fabricate flexible fibrous supercapacitors and lithium ion batteries with high specific capacitances and high specific capacities, respectively.
A Solid Oxide Electrolysis (SOE) short stack consisting of anode-supported cells (ASCs in fuel cell mode) was assembled in JÜLICH's F10-design. ASCs are based on Ni/8YSZ (8 mol-% yttria-stabilized zirconia) with an LSCF air electrode (La 0.58 Sr 0.4 Co 0.2 Fe 0.8 O 3-δ ) and 8YSZ electrolyte. A gadolinium-doped ceria…
Multi-scale thermal stability of (K,Na)NbO 3 -based perovskites with a high d 33 of 430 pC N −1 is investigated, revealing the origin of its large piezoelectricity.
Three acidotropic, near-infrared fluorescent probes based on piperazine-modified BODIPY dyes (A, B and C) have been developed for the sensitive and selective detection of lysosomal pH in living cells. Probes A and B display low solubilities in aqueous solutions, whereas probe C is highly water-soluble. The fluorescent…
II–VI semiconductor nanotubes are a recently developed class of nanomaterials whose unique photophysical properties are helping to create a new generation of nanomaterials in the field of photonics and microelectronics.
Current applications of carbon-based supercapacitors are limited by their low energy density. One promising strategy to enhance the energy density is to couple metal oxides with carbon materials. In this study, a porous MnCo2O4.5 nanoneedle/carbon aerogel hybrid nanostructure was synthesized by assembling MnCo2O4.5 na…
A high functionalization density and inter-planar bundling interaction remarkably improve both the storage capacity and lifetime of solar thermal fuels using an azobenzene/graphene nano-template.
In this study, the contribution of grain boundaries to the oxygen reduction and diffusion kinetics of La0.8Sr0.2MnO3 (LSM) thin films is investigated. Polycrystalline LSM thin films with columnar grains of different grain sizes as well as epitaxial thin films were prepared by pulsed laser deposition. (18)O tracer exch…
Production of fuels and chemicals from steam and/or CO2 with solid oxide electrolysis cells (SOEC) and electricity have attracted considerable interest recently. This paper is an extended version of the introductory lecture presented at the first Faraday Discussions meeting on the subject. The focus is on the state of…
The potential toxicity of nanoparticles has currently provoked public and scientific discussions, and attempts to develop generally accepted handling procedures for nanoparticles are under way. The investigation of the impact of nanoparticles on human health is overdue and reliable test systems accounting for the spec…
