A simple method to prepare multifunctional liquid marbles and dry water with magnetic, color, and fluorescent properties is presented. Multifunctional liquid marbles were prepared by encapsulation of water droplets using flocculated polymer latexes. First, the emulsion polymerization reaction of polystyrene and poly(b…
The use of personal protective gear made from omniphobic materials that easily shed drops of all sizes could provide enhanced protection from direct exposure to most liquid-phase biological and chemical hazards and facilitate the postexposure decontamination of the gear. In recent literature, lubricated nanostructured…
This work aims to reduce the prices of a wide range of nanomaterials which are unreachable in the industry by using natural sources as silicon and aluminum precursors. In a previous work, silicon and aluminum have been extracted from Volclay after applying the alkaline fusion process at 550 °C, and a water treatment o…
Metastable Ge 4 Bi 2 Te 7 is highly disordered; the average structure corresponds to the rocksalt type. The diffraction pattern shows diffuse streaks interconnecting Bragg reflections along all cubic 〈111〉 directions. These streaks exhibit satellite-like maxima and arise from vacancy ordering in non-periodically space…
A group-theoretical analysis was carried out to determine the possible orientation states of domains formed as a result of the `perovskite–brownmillerite' phase transition in SrCo 0.8 Fe 0.2 O 2.5 oxide with mixed ion–electron conductivity (MIEC). The results of the theoretical analysis agree with the experimental dat…
Two new amino core-substituted naphthalene diimides (cNDIs) bearing fluorinated side chains have been synthesised. Steady-state and time-resolved fluorescence spectroscopy reveals unprecedented optical properties for the cNDIs with high quantum yields of ∼0.8 and fluorescence lifetimes of ∼13 ns in a range of solvents…
A fast-response fringe-field switching (FFS) liquid crystal display using patterned common electrodes is proposed. By applying a restoring pulse voltage on common electrodes, the relaxation process of liquid crystals is expedited by the electric field. The average gray-to-gray decay time is over sevenfold faster compa…
This paper studies inhibition of steel-rebar corrosion in concrete immersed in 0.5 M H 2 SO 4 , simulating industrial/microbial environment by the leaf extract of Morinda lucida . Electrochemical monitoring methods were employed for testing different concentrations of the leaf extract admixed in duplicated specimens o…
Significant progress has been made in macromolecular crystallography over recent years in both the understanding and mitigation of X-ray induced radiation damage when collecting diffraction data from crystalline proteins. In contrast, despite the large field that is productively engaged in the study of radiation chemi…
In the paper, there are presented XPS results of surface layer formed after electrochemical polishing of AISI 316L (EN 1.4404) stainless steel at high current density of 2000 A/dm 2 . For the investigation, electrolyte based on orthophosphoric (H 3 PO 4 ) and sulfuric (H 2 SO 4 ) acids in proportions 3:2, was used. Th…
Abstract Herein, we describe an economical and convenient method to improve the performance of Pt/alumina catalysts for the water–gas shift reaction through surface modification of the catalysts with alkali hydroxides according to the solid catalyst with ionic liquid layer approach. The results are in agreement with o…
The synthesis of nanoparticle clusters, also referred to as colloidal clusters or colloidal molecules, is being studied intensively as a model system for small molecule interactions as well as for the directed self-assembly of advanced materials. This paper describes a technique for the interfacial assembly of planar…
The effects of different types of anionic polyacrylamide (PAM) on crystallization behavior of precipitated calcium carbonate (PCC) prepared via carbonation using calcium hydroxide and carbon dioxide gas. The percentage of aragonite phase increased higher reaction temperature. The use of anionic PAM resulted in the for…
A charge transfer (CT) mediated two-component, multistimuli responsive supergelation involving a L-histidine-appended pyrenyl derivative (PyHisOMe) as a donor and an asymmetric bolaamphiphilic naphthalene-diimide (Asym-NDI) derivative as an acceptor in a 2:1 mixture of H2O/MeOH was investigated. Asym-NDI alone self-as…
Highly dispersed FeOx was impregnated onto CeO 2 using the unique precursor Na/Fe-ethylenediaminetetraacetate (NaFeEDTA) at varying Fe surface density (0–1.5 Fe/nm 2 ). These catalysts were used for NO reduction by CO and were compared to a more traditional Fe(NO 3 ) 3 precursor impregnated on Na-promoted CeO 2 . Exte…
Fluorescent base analogues comprise a group of increasingly important molecules for the investigation of nucleic acid structure, dynamics, and interactions with other molecules. Herein, we report on the quantum chemical calculation aided design, synthesis, and characterization of four new putative quadracyclic adenine…
A new application of porous ceramics as the attenuative backing element in high-temperature transducers is introduced. By introducing pores of different volume fractions and various sizes into the ceramic matrix, acoustic impedance and attenuation can be controlled to match their optimal values as predicted by a simpl…
We demonstrate that hybrid systems of porphyrins and chirality enriched (6,5) single-walled carbon nanotubes (E-SWCNTs) are better candidates for photodynamic therapy (PDT) than their components alone. Surprisingly, the E-SWCNTs act as optical absorption enhancers to the porphyrins increasing the oxygen singlet produc…
Comparative Suzuki–Miyaura coupling polymerization (SMCP) studies with initiators generated in situ from 4-iododiphenylether ( 1 ), 4,4′-diiododiphenylether ( 2 ), 1,6-bis(4-iodophenoxy)hexane ( 3 ) and 1,4-bis(4-iodophenoxy)cyclohexane ( 4 ) result in bidirectional growth for 2, versus preferred monodirectional growt…
One of the greatest challenges in regenerative medicine is generating clinically relevant engineered tissues with functional blood vessels. Vascularization is a key hurdle faced in designing tissue constructs larger than the in vivo limit of oxygen diffusion. In this study, we utilized fibrin-based hydrogels to serve…
