The electrophysical reaction of rubidium polytungstate Rb4W11O35 ceramics (RPTC) on fast humidity impact has been investigated by studying the influence of wet air pulse of 1-3 s of duration on the peculiarities of dynamic current-voltage (I-V-) and charge-voltage (Q-V-) loops and transient current-time (I-t-) curves.…
In this paper we have developed a Finnis-Sinclair-type interatomic potential for W-W interactions that is based on ab initio calculations.The modified potential is able to reproduce the correct formation energies of self-interstitial atom (SIA) defects in tungsten, offering a significant improvement over the Ackland-T…
Pure polyaniline (PANI) films with different molecular chain packing states were successfully prepared by simply tuning the <italic>m</italic> -cresol content in the solvent.
Organizations around the world have called for the responsible development of nanotechnology. The goals of this approach are to emphasize the importance of considering and controlling the potential adverse impacts of nanotechnology in order to develop its capabilities and benefits. A primary area of concern is the pot…
We developed a new strategy to restrict the motions of AIE molecules through host-guest inclusion, affording a catalogue of new molecular luminogens.
Recent advances in the sol–gel process derived resorcinol-formaldehyde (RF) coating strategies offer new opportunities for the synthesis and applications of hollow carbon spheres (HCS). Due to the lack of an effective route for controlling the pore structures, the synthesis of RF resin derived HCS with a high specific…
We prepared hybrid halloysite nanotubes (HNT/sodium alkanoates) in which the inner cavity of the nanoclay was selectively modified. Physicochemical studies evidenced the interactions between HNT and sodium alkanoates, ruled out clay exfoliation, quantified the amount of the loaded substance, and showed an increase of…
Luminescent labels have been widely used for biological applications, primarily in bioimaging and assays. Recently much attention has been focused on the development of luminescent nanoprobes with excitation/emission maxima falling in the region of minimal tissue absorbance/autofluorescence between 650 and 1450 nm, an…
Porous graphene (PG) and graphene quantum dots (GQDs) are attracting attention due to their potential applications in photovoltaics, catalysis, and bio-related fields. We present a novel way for mass production of these promising materials. The femtosecond laser ablation of highly oriented pyrolytic graphite (HOPG) is…
Water-soluble, long wavelength fluorescent aggregation-induced emission (AIE)-active materials are in great demand for high contrast biosensing and bioimaging. The substitution position effects of the sulfonate group on the basis of two quinoline-malononitrile (QM) derivatives (EDS and EDPS) provide insight into effic…
The four-coordinate Fe(II) complex, PhB(MesIm)3Fe-N═PPh3 (1) has been previously reported to undergo a thermal spin-crossover (SCO) between high-spin (HS, S = 2) and low-spin (LS, S = 0) states. This complex is photoactive below 20 K, undergoing a photoinduced LS to HS spin state change, as determined by optical refle…
Some of the improvements in SHELX2013 make SHELXL convenient to use for refinement of macromolecular structures against neutron data without the support of X-ray data. The new NEUT instruction adjusts the behaviour of the SFAC instruction as well as the default bond lengths of the AFIX instructions. This work presents…
Surface-enhanced Raman scattering (SERS) hot spots occur when molecules are positioned near regions of strongly enhanced electromagnetic fields on the surface of nano-featured plasmonic substrates. The emission from the molecule is coupled out into the far field by the plasmon modes of the substrate, but due to the di…
An in situ carbon-grafted alkaline iron electrode prepared from the active material obtained by decomposing the α-FeC2O4·2H2O–polyvinyl alcohol (PVA) composite at 600 °C in a vacuum is reported. The active material comprises a mixture of α-Fe and Fe3O4 with the former as the prominent component. A specific discharge c…
Carbon dots (C-dots) have been proven to show the capability for direct reduction of Ag(+) to elemental silver (Ag(0)) without additional reducing agent or external photoirradiation by incubating Ag(+) with C-dots for 5 min in a water bath at 50 °C. Silver nanoparticles (Ag-NPs) are simultaneously formed with an avera…
Despite the high strength and stiffness of polymer nanocomposites, they usually display lower deformability and toughness relative to their matrices. Spider silk features exceptionally high stiffness and toughness via the hierarchical architecture based on hydrogen-bond (H-bond) assembly. Inspired by this intriguing p…
We present a spectroscopic and magnetic (both static and dynamic) characterization of two isostructural Dy and Er complexes evidencing that, despite the different types of magnetic anisotropy, the two molecules show similar slow relaxation of the magnetization in a static magnetic field.
The adhesion behaviors of superhydrophobic surfaces have become an emerging topic to researchers in various fields as a vital step in the interactions between materials and organisms/materials. Controlling the chemical compositions and topological structures via various methods or technologies is essential to fabricat…
Abstract The current development trend towards miniaturized portable electronic devices has significantly increased the demand for ultrathin, flexible and sustainable on-chip micro-supercapacitors that have enormous potential to complement, or even to replace, micro-batteries and electrolytic capacitors. In this regar…
Flexible lithium ion batteries (LIBs) have received considerable attention as a key component to enable future flexible electronic devices. A number of designs for flexible LIBs have been reported in recent years; in this article, we review recent progress. We focus on how flexibility can be introduced into each compo…
