Hollow composite microcapsules are prepared by the assembly of pre-formed nanocrystals of metal-organic frameworks (MOFs) around emulsion droplets, followed by interfacial polymerisation of the interior. The micropores of the MOF crystals embedded within a semipermeable hierarchically structured polymeric membrane are…
Fluorogenic molecules are important tools for advanced biochemical and biological experiments. The extant collection of fluorogenic probes is incomplete, however, leaving regions of the electromagnetic spectrum unutilized. Here, we synthesize green-excited fluorescent and fluorogenic analogues of the classic fluoresce…
Hydroxyapatite is a biocompatible material that is extensively used in the replacement and regeneration of bone material. In nature, nanostructured hydroxyapatite is the main component present in hard body tissues. Hence, the state of the art in nanotechnology can be exploited to synthesize nanophase hydroxyapatite th…
Living cells communicate and cooperate to produce the emergent properties of tissues. Synthetic mimics of cells, such as liposomes, are typically incapable of cooperation and therefore cannot readily display sophisticated collective behavior. We printed tens of thousands of picoliter aqueous droplets that become joine…
A new class of positive tone, permanent materials has been demonstrated, which are chemically amplified (CA), aqueous‐developable, and cross‐linkable. The intended purpose is a patterning and cross‐linking method to create high sensitivity permanent dielectrics for microelectronic devices and packages. The photochemis…
The surface of titanium dioxide (TiO2) nanoparticles was treated with a silane coupling agent of γ-aminopropyl-triethoxy silane. An optically active poly(amide-imide) (PAI) was synthesized by the indirect polycondensation reaction of the L-phenylalanine based diacid chloride and 4,4′-diaminodiphenylether in the presen…
The article represents the results of research in self-organization of new lanthanide systems in water-decanol medium. The systems are based on N,N-dimethyldodecylamine oxide, a zwitterionic surfactant. The study covers the complex formation of lanthanide ions with C12DMAO molecules and the influence of Ln(III) ions a…
Composite materials enjoy great attraction in material science. The objective of this research was to fabricate natural fiber reinforced polymer matrix composites and to increase performances through physical and chemical methods. Areca nut fiber (50 % by weight) reinforced polycaprolactone (PCL) based unidirectional…
We examine the hydrodynamic behaviour of a nematic liquid crystal confined between two parallel electrodes and subject to a non-uniform electric field across the layer. By decoupling the Ericksen–Leslie equations for the nematic, we are able to derive a dynamic equation for the director orientation which is not explic…
Therapeutic nanosystems based on magnetic mesoporous silica nanoparticles are successfully obtained by a facile, reproducible and time-saving sonochemical method. Hydrophilic citrate-capped magnetite nanoparticles of about 20 nm are firstly prepared by ultrasound-assisted chemical precipitation. Secondly, freshly-drie…
The modern progress of bionanotechnologies and molecular electronics requires development of new organic materials with specific characteristics for formation of ultrathin films with specified magnetic or conductive properties. Here we need new experimental and computing methods creation. In this work a new effect is…
Polycrystalline silver(I) deca-calcium heptakis(orthophos-phate), AgCa10(PO4)7, was obtained by solid-state reaction. It is isotopic with members of the series MCa10(PO4)7 (M = Li, Na, K and Cs), and is closely related to the structure of β-Ca3(PO4)2. The crystal structure of the title compound is built up from a fram…
The bioconjugation of fluorescent quantum dots (QDs) and purification of QDs bioconjugates are of vital importance in bioapplications. In this paper, we systematically investigated the purification efficiency of QDs bioconjugates and their stability during separation process by using size exclusion chromatography (SEC…
A series of novel thermosensitive polymers were synthesized with acrylamide and thermosensitive macromonomers by radical polymerization in water solution. The structures of the copolymers were characterized by 1H‐NMR. The effects of the polymer concentration, NaCl concentration, shear rate, and chemical structure on t…
Recent advances in nanofabrication techniques allow for the manufacture of optical metamaterials, bringing their unique and extraordinary properties to the visible regime and beyond. However, an analytical description of optical nanoplasmonic metamaterials is challenging due to the characteristic optical behavior of m…
NE0047 from Nitrosomonas europaea has been annotated as a zinc-dependent deaminase; however, the substrate specificity is unknown because of the low level of structural similarity and sequence identity compared to other family members. In this study, the function of NE0047 was established as a guanine deaminase (catal…
It is shown that ab initio simulation can be used as a powerful complementary tool in the interpretation of the experimental reflectance spectra R(ν) of crystalline compounds. Experimental frequencies and intensities are obtained from a best fit of R(ν) with a set of damped harmonic oscillators, whose number and initi…
The authors report an eco-friendly way of synthesizing silver nanoparticles (SNPs) using tomato fruit extract and its characterization using XRD, SEM, particle size analyzer, and UV-Visible spectroscopy. The SNPs were used along with activated charcoal as nanocomposite for water purification and the efficiency of the…
Layered double hydroxides (LDHs), also called anionic clays, consist of cationic brucite-like layers and exchangeable interlayer anions. These hydrotalcite-like compounds, with Zn and Al in the layers and chloride in the interlayer space, were prepared following the coprecipitation method at constant pH. The affinity…
