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…
Influence of Graphite Characteristics on the Electrochemical Intercalation of Bis(trifluoromethanesulfonyl) imide Anions into a Graphite-Based Cathode, Placke, Tobias, Rothermel, Sergej, Fromm, Olga, Meister, Paul, Lux, Simon Franz, Huesker, Jessica, Meyer, Hinrich-Wilhelm, Winter, Martin
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…
Aromatic peptide amphiphile hydrogelators commonly utilise the fluorenyl-9-methoxycarbonyl moiety as an N-terminal capping group. Material properties and spectroscopic techniques show the influence of alternative linkers between the fluorenyl moiety and the peptide. This study establishes whether methoxycarbonyl is an…
Ultrathin cobalt phosphate (CoHPO4 · 3H2O) nanosheets are successfully synthesized by a one pot hydrothermal method. Novel CoHPO4 · 3H2O ultrathin nanosheets are assembled for constructing the electrodes of supercapacitors. Benefiting from the nanostructures, the as-prepared electrode shows a specific capacitance of 4…
A novel nano-conjugate containing ultrasmall water-soluble AuNCs protected by ovalbumin as the fluorescent part, folic acid as the targeting ligand and a homopolymer N-acryloxysuccinimide as the linker has been investigated. Moreover, specific staining of HeLa cells by the nano-conjugate has been demonstrated.
We demonstrate the potential of a nitrogen-doped cuprous oxide (Cu2O:N) film as a p-type hole-transporting layer for photovoltaic devices. To reduce back-contact resistance and create an electron-reflecting back surface field, high carrier density and appropriate work function are desired for the layer. Its electrical…
Co-doped ZnO nanoparticles are synthesized by co-precipitation method. The incorporation of Co ions into ZnO wur- zite structure with increasing Co concentrations was followed by X-ray diffraction. Sample structures were further studied by infrared spectra, from which a broad and strong absorption band in the range of…
A facile and sustainable approach has been successfully devised to fabricate ultrafine (100–500 nm) highly porous activated carbon fibers (ACFs) by electrospinning of aqueous solutions of predominantly alkali lignin (low sulfonate content) followed by simultaneous carbonization and activation at 850 °C under N2. Incor…
Tungsten (W) is a candidate for the plasma facing component material of fusion reactors. During fusion reactor operation, not only displacement damage but also transmutation elements such as rhenium (Re) and osmium (Os) are produced in W by neutron irradiation. To understand the irradiation response of W in a fusion r…
With regard to the requirements of EU directive 2010/31/EU [1] is necessary in the construction and reconstruction of existing buildings to implement effective measures for reducing their energy consumption. From 1. 1. 2021 should get virtually all new buildings, buildings with almost zero energy. These facts mean tha…
We employ ab-initio electronic structure calculations to search for spin gapless semiconductors, a recently identified new class of materials, among the inverse Heusler compounds. The occurrence of this property is not accompanied by a general rule and results are materials specific. The six compounds identified show…
