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…
The advancement of nanomedicine and the increasing applications of nanoparticles in consumer products have led to administered biological exposure and unintentional environmental accumulation of nanoparticles, causing concerns over the biocompatibility and sustainability of nanotechnology. Upon entering physiological…
Indium-doped (In-doped) ZnO nanostructures with four different morphologies, namely nanochips, nanotripods, nanorods, and nanodisks, have been successfully synthesized by a simple hydrothermal method. The effects of indium dopant and various morphologies on the structural, optical and field-emission properties of thes…
We demonstrate a tandem truncation-functionalization strategy using the 3D covalent organic framework, COF-102. Allyl groups incorporated within the pore walls were subjected to thiol-ene coupling conditions, achieving high conversions and maintaining the crystallinity and permanent porosity of the parent framework.
Fingerprint signatures of circularly polarized luminescence (CPL) are observed from Staphylococcus aureus nuclease (SNase), bovine serum albumin (BSA), and insulin (Ins) labeled with europium(III) complexes containing a β-diketonate ligand, where SNase shows a virtually opposite CPL sign compared to those of BSA and I…
The Mott phase transition compound vanadium dioxide (VO2) shows promise as a thermochromic smart material for the improvement of energy efficiency and comfort in a number of applications. However, the use of VO2 has been restricted by its low visible transmittance (Tvis) and limited solar modulation ability (ΔTsol). M…
Insights into the origin of the fluorescence responsive to protonation-deprotonation stimuli were provided through the study on the crystals of a new stimuli-responsive molecule BP3VA. And the transformation between microcrystals demonstrated the varying emissions of the BP3VA powder.
Development of an easy sustainable synthetic pathway towards oxide nanomaterials (NMs) is a necessary challenge for nanotechnology research workers. Additionally, antimicrobial activity of oxide nanoparticles against multi drug resistance pathogenic bacteria motivates scientists to focus their research on oxide materi…
The release of nanomaterials from products and applications that are used by industry and consumers has only been studied to a very limited extent. The amount and the characteristics of the released particles determine the potential environmental exposure. In this work we investigated the release of Ti from paints con…
This study examines a sequestration of CO2 using sterically hindered 2-amino 2-(hydroxymethyl)-1,3-propanediol in the presence and absence of the carbonic anhydrase enzyme to obtain a CaCO3 with a polymorphic crystal composition that depended on the pH, temperature, or mole ratio of the reactants in the reaction mixtu…
CuO nanosheets (NSs)/reduced graphene oxide (rGO) hybrid lamellar films were prepared by vacuum filtration of CuO NSs/GO composite dispersions, followed by hydrothermal reduction. The CuO NSs/GO composite dispersions were assembled electrostatically by mixing a negatively charged GO sheets aqueous solution with a posi…
A series of monometallic borohydrides and borohydride eutectic mixtures have been investigated during thermal ramping by mass spectroscopy, differential scanning calorimetry, and photography. Mixtures of LiBH4-NaBH4, LiBH4-KBH4, LiBH4-Mg(BH4)2, LiBH4-Ca(BH4)2, LiBH4-Mn(BH4)2, NaBH4-KBH4, and LiBH4-NaBH4-KBH4 all displ…
Upon 20% Te substitution, the band gap decreases from 0.8 eV to 0.65 eV. Rising temperature promotes minority carrier jumps across the band gap, thereby improving electrical conductivity. With low thermal conductivity and large Seebeck coefficients, a remarkable ZT of 0.71 at 873 K is achieved for BiCuSe0.94Te0.06O.
Hydrogen is an key future fuel of interest because it is considered as an efficient energy carrier, like electricity, releasing only water when combining with oxygen (e.g. in a fuel cell) and therefore has no negative impact on the environment. Unfortunately we are not yet able to clear the economical and engineering…
Liquid crystals with 1,3,4-oxadiazole units in the aromatic core have attracted considerable attention due to their rich mesophases, high photoluminescence quantum yields, good electron transporting ability and excellent thermal stabilities. In this feature article, 1,3,4-oxadiazole-based liquid crystals are classifie…
Synchrotron XPS was used to investigate a series of chemically-synthesised, atomically-precise gold clusters Au(n)(PPh(3))(y) (n = 8, 9, 11 and 101, with y depending on cluster size) immobilized on titania nanoparticles. The gold clusters were washed with toluene at 100 °C or calcined at 200 °C to remove the organic l…
Well-shaped CuInS2 nanopyramids and nanodisks were synthesized by a wet-chemical method. The phase structure was controlled by the coordination strength between solvent and metal precursors. Zincblende CuInS2 structure was obtained when copper iodide, indium acetate and 1-dodecanethiol were heated at 220 °C in 1-octad…
The early diagnosis of diseases related to phosphate metabolism is very important for preventing, in most cases, severe kidney failure and cardiovascular events that have an increased risk of death. In this work, we present biofunctionalized quantum dots (b-QDs) prepared with chitosan and its chemically modified deriv…
Carbon dots were used as a reducing agent for the synthesis of Pd nanoparticles coated with ultrathin carbon dot shells of ca. 4 nm. The resulting composite nanoparticles showed high catalytic activity for the Heck and Suzuki coupling reactions.
