In this paper, we demonstrate a simple and practical method to prepare chemically crosslinked gelatin-based hydrogels using β-cyclodextrin (β-CD) that plays a dual role as a crosslinker as well as a host molecule for enhanced binding of anticancer drug methotrexate (MTX), to achieve high drug loading level as well as…
We report the design and realization of double shelled @CeO2/M@M/TiO2 (M = Au and/or Pd) nanospheres with dual noble metal nanoparticles encapsulated in metal oxide shells via a layer-by-layer deposition process followed by an alkali etching method. The resulting nanospheres possess uniform sizes, variable shell compo…
Triphenylphosphonium-fluorochromes (TPP-fluorochromes) are a new class of spectrally variable, mitochondrially targeted probes, with an [(18)F] labeling option which, when enabled, allows imaging of a cardiac perfusion deficit using PET/CT.
We investigated the mechanical properties of metal–organic framework thin-film coatings grown by an electrochemical method, which allows fast deposition in environmentally friendly solvents. For the first time, Cu(CHDA) and Cu(INA)2 are electrochemically synthesised as dense coatings on Cu-electrodes, alongside the we…
It is well-known that amino acids deposited on some inorganic oxides undergo peptidic condensation. It is seldom realised however that a large diversity of behaviours can be observed in such systems. Here we use the apparently simple case of glycine-non-porous silica as a reference system, in which glycine (Gly) dimer…
p-Type nanocrystal NiO-based thin-film transistors (TFTs) are fabricated by simply oxidizing thin Ni films at temperatures as low as 400 °C. The highest field-effect mobility in a linear region and the current on-off ratio are found to be 5.2 cm(2) V(-1) s(-1) and 2.2 × 10(3), respectively. X-ray diffraction, transmis…
Esterifications of poly(methacrylic acid) (PMAA) and poly(acrylic acid) (PAA) have been investigated with a wide variety of halogenated compounds such as iodide, bromide, and chloride using 1,1,3,3-tetramethylguanidine as a promoter. The results demonstrate that the poly(meth)acrylates can be obtained with an excellen…
BACKGROUND: Scanning electron microscopy (SEM) has been used for high-resolution imaging of plant cell surfaces for many decades. Most SEM imaging employs the secondary electron detector under high vacuum to provide pseudo-3D images of plant organs and especially of surface structures such as trichomes and stomatal gu…
Aligned carbon nanotube–oriented poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) composites show an unexpectedly high catalytic activity which greatly exceeds the aligned individual components, the non-aligned composite counterpart, and even conventional platinum. When they are used as counter electrodes in d…
In this work we further the structural characterization of the recently discovered (C3N2H5)[Mn(HCOO)3] metal–organic framework with perovskite-like structure, and we present its magnetic and dielectric properties up to 350 K. At low temperature, the C3N2H5+ imidazolium cations, that sit oblique within the cavities of…
Porous single-crystal-like CdS nanosheets fabricated through a facile cation-exchange strategy exhibit a noticeable photocatalytic activity for aerobic oxidative coupling of amines to imines with 1 atm O2 under visible-light irradiation (λ > 420 nm) at room temperature.
Epoxides are important intermediates of atmospheric isoprene oxidation. Their subsequent reactions in the particle phase lead to the production of organic compounds detected in ambient aerosols. We apply density functional theory to determine the important kinetic factors that drive epoxide reactions in the particle p…
Black silicon is an interesting surface texture for solar cells because of its extremely low reflectance on a wide wavelength range and acceptance angle. In this paper we present how black silicon (b-Si) texturization can be applied on the boron doped front surface of an n-type solar cell resulting in an efficiency of…
The paper deals with the effect of basalt powder on the rheological properties of fresh cement mortars and physical properties of hardened mortars. The cement mortar was modified by basalt powder in amount 10, 20 and 30% by weight of cement (replacement of cement). The consistence of fresh mortars should have the qual…
A facile spray drying technique has been developed for large-scale and template-free production of nanoporous silica with controlled morphology, large pore size, and high pore volume, using commercially available fumed silica, Aerosil 200, as a sole precursor. This approach can be applied to the preparation of functio…
Herein we demonstrate the formation of the first tetrastable naphthalenediimide (NDI, 1a) molecule having multiple distinctly readable outputs. Differential response of 1a to fluoride anions induces intramolecular charge transfer (ICT), single/double electron transfer (SET/DET) leading to a set of combinational logic…
The antiviral activity of several cationic compounds - cetyltrimethylammonium bromide (CTAB), chitosan, nisin, and lysozyme - was investigated on the bacteriophage c2 (DNA head and non-contractile tail) infecting Lactococcus strains and the bacteriophage MS2 (F-specific RNA) infecting E. coli. Firstly, these activitie…
Thin films and coatings play an essential role in the whole range of applications. The example par excellence are optical thin films that broaden the possibilities of design of optical components. Analogically to other applications of thin films their mechanical properties are very important for their successful appli…
Highly crystalline SnO2 nanowires were synthesized and functionalized with copper particles in a CVD using Sn(OBut)4 and [CuII((C5H4N)(CHCOCF3))2]2 (1) as precursors respectively. Controlled oxidation of Cu to CuO led to the formation of CuO@SnO2 p–n heterojunctions, which were found to be highly sensitive and selecti…
We designed an anisotropic electrode, in which Li(+) ion insertion and diffusion are anisotropic, by controlled growth of TiO2 nanosheets parallel to the surface of graphene paper. The anisotropic electrode gives a gravimetric capacity of 112 mA h g(-1) at an ultra-high rate of 100 C (corresponding to 36 s of charge-d…
