Guanosine and its derivatives have a high potential for self-recognition and self-assembly, as well as the recognition ability for other biologically important molecules. This book explores in detail these properties with the goal of increasing knowledge of the basic principles of guanosine-assembly, synthesis of new…
Metal oxide nanoparticles (NPs) are reported to impact plant growth in hydroponic systems. This study describes the impact of commercial CuO (\50 nm) and ZnO (\100 nm) NPs on wheat (Triticum aestivum) grown in a solid matrix, sand. The NPs contained both metallic and non-metallic impurities to different extents. Dynam…
Collagen, glycosaminoglycans and elastin are the major components of heart valves. This work examines the roles of the composition of the collagen-based scaffolds on the microstructures, mechanical properties, and bioactivities. Scaffolds (with up to 80% elastin or 50% chondroitin-4-sulfate) were prepared by freeze dr…
In the present investigation, synthesis of silver nanoparticles by using rhizome extracts of Dioscorea oppositifolia L. and characterized by using UV spec, FT-IR, DLS and TEM. The extract incubated with AgNo 3 showed colour changed of the extract from greenish to reddish brown with intensity increasing during the peri…
Five irradiated fuel compacts from the AGR-1 experiment have been examined in detail in order to assess in-pile fission product release behavior. Compacts were electrolytically deconsolidated and analyzed using the leach-burn-leach technique to measure fission product inventory in the compact matrix and identify any p…
Egyptian spinning factories are faced to deterioration in their quality capabilities in the last years due to instability in cotton fiber types and quantities. This affects Quality and efficiency of knitting and weaving process as they depend on yarn properties. Instead of working with different types of Egyptian cott…
In this paper, a chiral metamaterial (CMM) with complementary U-shaped structure assembly is proposed. The microwave experimental and simulated results of the proposed complementary structure exhibit giant optical activity. The experimental results are in good agreement with the numerical ones. The retrieval results r…
N, N'-bis (Salicylidene)-1, 4-Diaminophenelyne (SDP) and N, N'-bis (3-Methoxy Salicylidene)-1, 4 Diaminophenelyne (MSDP) were synthesized, and their molecular structure were determined by FT-IR and 1 H NMR. The corrosion inhibitions of these compounds on AA6061 in 1M Hydrochloric acid were evaluated by weight loss met…
In this report, we report a novel pH-controlled recognition method for the discriminative detection of Mn(II) and Cu(II) ions via CdTe QD fluorescence sensing. The detection limits of Mn(II) are 10 nmol L−1 to 5 μmol L−1. Our results indicate that the sensitivity of QD fluorescence sensing to Mn(II) strongly depends o…
We create an interface between a cholesteric liquid crystal (CLC) and an isotropic liquid (silicone oil) at which homeotropic anchoring leads to a well aligned cholesteric layer and the formation of the fingerprint texture. Fluorescent colloidal particles with planar surface anchoring are dispersed in the CLC and subs…
In this work, the ability to foam semi-crystalline natural-based polymers by supercritical fluid technology is evaluated. The application of this technique to natural polymers has been limited due to the fact that they are normally semi-crystalline polymers, which do not plasticize in the presence of carbon dioxide. T…
Advances in the life sciences are now closely linked to the availability of new experimental tools that allow for the manipulation of biomolecules and the study of biological processes at the molecular level. In this context, we have optimized a synthesis process to obtain glutathione-capped fluorescent CdS nanopartic…
This paper presents an analytical review of data on the interaction of volatile corrosion inhibitors with the atmosphere, vaporization processes, methods of experimental and computational estimation of the vapor pressure of organic compounds, and effects of vaporization conditions and compound structure on vapor press…
Combinatorial libraries of substituted tetrapyrrole macrocycles, which can now be prepared via a variety of approaches, typically are rich in isomers. Terminology for describing such isomers (due to distinct patterns of peripheral substituents) is delineated in several illustrative examples. A hierarchical relationshi…
Thin composite films of the mussel adhesive proteins (Mefp-1) and ceria nanoparticles were deposited on substrate surfaces by alternating immersions. The film formation was studied by quartz crystal microbalance with dissipation (QCM-D) monitoring. Both the changes in frequency and dissipation recorded by QCM-D demons…
Nonspherical polystyrene particles tuned from collapsed spheres (mushroom cap and hemisphere shapes) to two-lobed dimers are synthesized by seeded emulsion polymerization. The presence of a swelling solvent and additions of divinylbenzene crosslinker facilitate shape control through directing phase separation of the p…
We demonstrate that linear-dendritic shape-isomerism can have an impact on the gelation potential of peptides based on lysine, but the architectural effects can be inverted depending on the choice of functional groups, with the nature of these protecting groups dominating the gelation ability.
Three new thiogermanates, (trenH2)2[Ge2S6] (1, tren = tris(2-aminoethyl)amine), [Eu(dien)3]2[Ge2S6]Cl2 (2, dien = diethylenetriamine) and [Y2(tepa)2(μ-OH)2(μ-Ge2S6)](tepa)0.5·H2O (3, tepa = tetraethylenepent-amine), were solvothermally synthesized and characterized. Both 1 and 2 are composed of discrete [Ge2S6]4− anio…
A key frontier in nanomaterial fabrication is the integration of different materials within the same structure as a means to increase functionality. Herein, a facile solution route for the synthesis of nanocomposites consisting of PbSe and gold is reported. It has been found that the molar ratio of PbSe/Au has great i…
This work reports the first example of the biofunctional magnetic nanoparticles as a “magnetic dock” for directly sorting proteins inside live cells. We decorate the iron oxide nanoparticles with the ligands that bind selectively to fusion proteins consisting of the proteins of interest (POIs) and the ligand receptors…
