A carbon quantum dot (CQD)-protoporphyrin (IX) sensitisier conjugate was designed to exploit the large two-photon absorption cross section of CQDs and enable the indirect excitation of the sensitiser with 800 nm irradiation via FRET.
Improvement of energy density is an urgent task for developing advanced supercapacitors. In this paper, aqueous supercapacitors with high voltage of 1.8 V and energy density of 29.1 W h kg(-1) were fabricated based on carbon nanofibers (CNFs) and Na2SO4 electrolyte. The CNFs with radially grown graphene sheets (GSs) a…
The recently developed fluorescent organic nanocrystals and non-doped nanoparticles (FONs) occupy a special position among other nanoparticle systems that are used for studying a variety of fundamental processes in the life sciences. Understanding their particular photophysical behavior allows proper design of FONs. T…
In this work, a facile and novel wet chemical method is adopted to synthesize PbTe–graphene nanocomposites, and the thermoelectric properties of the sintered bulk materials are discussed in detail. An intercalative nanostructure is formed by using commercial graphene oxide nanosheets as both the dispersant and the two…
The magnetic properties of monodisperse FeO-Fe3O4 nanoparticles with different mean sizes and volume fractions of FeO synthesized via decomposition of iron oleate were correlated to their crystallographic and phase compositional features by exploiting high resolution transmission electron microscopy, X-ray diffraction…
Changing the linking positions of alkoxy chains can significantly alter the aggregation-induced emission and piezofluorochromic activities of 9,10-bis(alkoxystyryl)anthracenes.
Color-tunable phosphors of ZnWO4:x mol% Bi3+, 3 mol% Eu3+ (x = 0.5, 1, 2, 3, 4, 5) were prepared through a precipitation method and their luminescence properties were investigated as a function of Bi3+ concentration. The most intense 616 nm emission indicates that Eu3+ occupies the Zn2+ sites without inversion symmetr…
CuS-graphene nanosheet (GNS) composites with well-defined morphology have been successfully fabricated via a simple one-pot hydrothermal route by using thioacetamide (TAA) as both the sulfur source and reducing agent. The as-prepared CuS-GNS composites with an appropriate content of graphene exhibited an even higher p…
A nanocrystalline Ce–Sm–oxide solid solution, with an excellent redox property and remarkable oxygen storage/release capacity, has been synthesized by means of a simple and highly practicable coprecipitation method. To understand the thermal and textural stability, the synthesized catalyst was subjected to calcination…
A periodic porous structure is introduced for the first time into a VO2(M) film to block only heat rather than light. The as-obtained 2D and 3D films show excellent visible transmittance and solar modulation efficiency.
A bio-based epoxy monomer (GA-II) was synthesized from renewable gallic acid. The aromatic group contained made it capable of being absorbed onto the surface of graphene via strong π–π interactions, which was proven by Raman spectra and UV spectra. The GA-II anchored graphene was easily homogeneously dispersed in the…
The synthesis of multifunctional magnetic nanoparticles (MF-MPs) is one of the most active research areas in advanced materials as their multifunctional surfaces allow conjugation of biological and chemical molecules, thus making it possible to achieve target-specific diagnostic in parallel to therapeutics. We report…
Half-Heusler thermoelectrics offer the possibility to choose from a variety of non-toxic and earth-abundant elements. TiNiSn is of particular interest and - with its relatively high electrical conductivity and Seebeck coefficient - allows for optimization of its thermoelectric figure of merit, reaching values of up to…
We report a new ligand directed chemical synthesis of hexagonal shaped zinc nanoplates. The produced nano-hexagons (NHexs) display a thickness of about 20–40 nm and diameter ranging from about 200–350 nm, exhibiting a high aspect ratio. While zinc is traditionally highly susceptible to oxidation, these high surface ar…
A new type of degradable, nanoscopic polymer assembly containing ultra-high levels of drug loading via covalent attachment within amphiphilic core–shell nanoparticle morphology has been generated as a potentially effective and safe anti-cancer agent. Poly(ethylene oxide)-block-polyphosphoester-based paclitaxel drug co…
Hierarchical structure Ti-doped WO3 thin films are prepared by a template-free hydrothermal method. The influence of Ti doping on the electrochromic properties of WO3 thin films is investigated in the visible-infrared region. Ti doping can lead to significant surface morphology change and lower the crystallization, wh…
Two-dimensional (2D) reduced graphene oxide/titanium dioxide nanorod array/reduced graphene oxide (rGO/TiO2 NR/rGO) with a porous hybrid structure was fabricated as an electrode material for use in electrochemical supercapacitors. The structural, morphological, and compositional characteristics of the resulting electr…

The development of flexible, sustainable, and efficient energy storage has recently attracted considerable attention to satisfy the demand for huge energy and power density and meet future societal and environmental needs. Consequently, numerous studies have focused on the design/development of nanomaterials based on…
The geometrical concept and structural framework of quasicrystals (QCs) were established shortly after the discovery of QCs. Specifically, the static and dynamic properties of the atoms and the electronic structures of quasiperiodic lattices were theoretically developed. Experimental studies lagged behind theoretical…
