Several conjugates of metallophthalocyanines with deoxyribooligonucleotides were synthesized to investigate sequence-specific modification of DNA by them. Oligonucleotide parts of these conjugates were responsible for the recognition of selected complementary sequences on the DNA target. Metallophthalocyanines were ab…
Granular beds are an important simulant of damaged PBXs which have developed porosity. Recent developments in X‐ray microtomography have provided us with the ability to resolve energetic crystals contained within a polymer matrix or granular bed. Although electron microscopy offers better spatial resolution, it yields…
This paper summarizes a laboratory investigation into the effects that range top diversity, range accessories (including shelving and a salamander), and hood dimensions (including hood height and depth and reservoir volume) have on hood performance with respect to the minimum exhaust rate required for complete capture…
It is reported the improving of the solubility and UV stability of furosemide, a poorly water soluble diuretic, by complexation with β-cyclodextrin. There is presented the synthesis of the inclusion complexes of furosemid with β-cyclodextrin by co-precipitation, and freeze drying methods, and their characterization. T…
Amorphous carbon films were synthesized on top of polyethylene terephthalate (PET) substrates using atmospheric-pressure glow (APG) plasma CVD equipment which we originally designed and set up. Plasma was generated between two metal electrodes one of which was covered with a dielectric plate. By varying dielectric con…
Precise magnetization measurements have been made on the weak itinerant electron ferromagnet CoVSb. The magnetic moment at 4.2 K and the Curie temperature TC are 0.16 μB/f.u. and 45 K, respectively. Below 10 K, the decrease in the square of the spontaneous magnetization Ms(T)2 is proportional to T2. However, over a wi…
Abstract The optical and resonance Raman spectra (RR) of bis(phloroglucinol)squaraine (I) and bis(resorcinol)squaraine (II) were investigated, revealing that the equilibria between the neutral and anionic species present in solution explain the experimental observations much better than the previously proposed aggrega…
Abstract Geometry, vibrational wavenumbers, and several thermodynamic parameters have been calculated using ab initio quantum chemical methods for the 3‐aminobenzonitrile molecule for the first time. The results were compared with experimental values. With the help of specific scaling procedures, the observed vibratio…
Nanorods of wurtzite ZnS were synthesized by a hydrothermal method at 200°C and a co-precipitation method at room temperature in the presence of ethylenediamine (en) aqueous solutions. It was found that the wurtzite ZnS nanorods with uniform diameter around 80±20 nm, length about 300±100 nanometer appears at a proper…
This work presents the electrostatic properties of knitted fabrics destined for protective clothing used to protect humans against static electricity. The aim of this research work is to estimate the electrostatic properties of knitted fabrics in dependence on the degree to which their structure is filled with basic y…
Nanotechnology is evolving to become a leading industry. However, there is a great deal of uncertainty surrounding the potential health effects of nanomaterials and its components. This study focuses on the hazards and risks that nanomaterials pose to physical and environmental health together with the risks posed dur…
A technique for fabricating high-aspect-ratio Ni structures has been developed using wet Si processing. Si ( 100 ) was initially etched in HF to form high-aspect-ratio (exceeding 200) micrometer-sized pores. By introducing the as-etched Si into a defined Ni 2 + solution, Ni deposits grew rapidly and replaced the Si on…
In this study, we synthesized two novel carboxylic acid and carboxylate compounds, both of which had an amide group linked with an azomethine moiety to introduce photoinduced switching of the intramolecular NH...O hydrogen bond. We suggest that the cis-carboxylate compound forms a stronger intramolecular NH...O hydrog…
Melt-blowing of lyocell solutions is a novel way of producing non-woven webs of very fine fibres. Earlier work in this area has been rather exploratory in nature. As yet, there has been no report on the outcome of using solutions of different characteristics. This paper presents a systematic study of the influence of…
The synthesis of a new H 4 do3aPPh ligand related to the 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetate (dota) family is described together with its erbium(III) complexes. The complexes constitute a new type of coordination compounds within the Ln-dota family, with the macrocycle protonated and erbium ions above…
The formation of solid films at the air-solution interface is a common phenomenon, however, these films have largely not been explored from a materials point of view. In solutions containing inorganic species with surfactants these films, which can be several microns thick, have a highly organised nanoscale structure…
Recent advances in modeling the unique optical properties of nanoparticles and nanocomposites pave the way for designing and modeling coatings.
The microstructure, martensitic transformation temperatures and shape memory properties of Co-Si binary alloys were investigated by means of optical and transmission electron microscopy, differential scanning calorimetry and a shape memory test. The ε martensite phase with a hexagonal close-packed (hcp) structure was…
The direct synthesis of phenol by hydroxylation of benzene with hydrogen peroxide over a vanadium substituted heteropolymolybdic acid catalyst was investigated at 70 ?C. Hydrogen peroxide was used as the oxidant while 36 wt.% acetic acid was employed as the solvent. After 100 minutes, the selectivity for phenol was 93…
A solid membrane of poly(2-ethylhexyl methacrylate-co-vinylpyridine) containing photochromic 6′-nitrospiropyran was prepared. In the rubbery copolymer membrane (Tg = −9 °C), the merocyanine (MC) form of the spiropyran isomerized into the spiro (SP) form by thermal decay after irradiation with UV light. The resulting d…
