Composition-structure–physical property relationship and nonlinear optical properties of multiferroic hexagonal ErMn 1−x Cr x O 3 nanoparticles
Nanocrystalline multiferroic ErMn <sub>1−x</sub> Cr <sub>x</sub> O <sub>3</sub> exhibits canted antiferromagnetism with a spin-glass transition and strong nonlinear optical absorption.
Liquid crystalline macrocyclic azacalix[4]pyridine and its complexes with the zinc ion: conformational change from the saddle to flattened shape
Substituted with four 3,4,5-tris(alkoxy)benzyl mini-dendrons, azacalix[4]pyridine (1) with the saddle-shaped core is the first liquid crystal (LC) of heteracalixaromatics. Conformational regulation of azacalix[4]pyridine by complexing with the zinc ion leads to a significant change in LC properties.
The first 3D and trinuclear cyano-bridged Fe III –Fe III (CN) 6 complexes: structure and magnetic characterizations
Crystal structures and magnetic properties of 3D <italic>cis</italic> -cyano-bridged and 2D <italic>trans</italic> -cyano-bridged trinuclear Fe <sup>III</sup> –Fe <sup>III</sup> (CN) <sub>6</sub> structures are reported.
Targeted and controlled drug delivery using a temperature and ultra-violet responsive liposome with excellent breast cancer suppressing ability
Drug delivery systems (DDS) with favorable serum stability, high intra-tumor accumulation and tumor specific drug release are highly desired for promoting chemotherapeutic efficacy.
Fluorescent polymeric nanoparticles with ultra-low CMC for cell imaging
A novel amphiphilic copolymer is facilely prepared through radical polymerization and subsequent ring-opening crosslinking based on poly(ethylene glycol) monomethyl ether methacrylate, glycidyl methacrylate, and amino-terminated aggregation-induced emission dye. Such a cross-linked polymer can self-assemble into nanop…
Speed versus stability – structure–activity effects on the assembly of two-component gels
Modifying the peripheral peptides dramatically changes the time required for gelation under ambient conditions, whilst an enthalpy–entropy balance means that as the temperature increases, the thermal stability of the gels is very similar.
Thermal energy harvesting for large-scale applications using MWCNT-grafted glass fibers and polycarbonate-MWCNT nanocomposites
The thermoelectric properties of multi-wall carbon nanotube (MWCNT) -grafted glass fiber yarns (GF-CNT) and their epoxy model composites, as well as of polymer nanocomposites consisting of a polycarbonate (PC) matrix filled with differently functionalized MWCNTs have been examined. The GF-CNT hierarchical multi-scale…
Plasma as a tool for enhancing insulation properties of polymer composites
A novel method for improving the CTI performance level of polyphenol composites by oxygen plasma selective etching.
Freshwater algal diversity of the South-Tajik Depression in a high-mountainous extreme environment, Tajikistan
The research on algal communities' response to altitude and altitude-related climatic conditions is sparse. So far, a full, accessible list of algae from the water bodies of the South-Tajik Depression has not been available. We compiled an algal species list of 1190 taxa that were revealed by us or listed in reference…
Anion selectivity in ion exchange reactions with surface functionalized ionosilicas
Mesoporous imidazolium functionalized surface functionalized ionosilicas have been investigated as anion exchange materials for the adsorption of oxo-anions in aqueous media. We studied particularly pertechnetate adsorption and could show that solids bearing long chain substituted imidazolium groups are highly efficie…
Purification and structural characterization of “simple catechol”, the NGAL-siderocalin siderophore in human urine
The identification of ligands that bind the protein Neutrophil Gelatinase-Associated Lipocalin (NGAL, Siderocalin, Lipocalin-2) have helped to elucidate its function. NGAL-Siderocalin binds and sequesters the iron loaded bacterial siderophore enterochelin (Ent), defining the protein as an innate immune effector. Simpl…
Synthesis and characterization of exfoliated PMMA/Co–Al LDH nanocomposites via solvent blending technique
PMMA/Co–Al LDH nanocomposites prepared by a facile method displayed superior thermal properties in comparison with pristine PMMA.

Hollow silica spheres with different hollow size and shell thickness were synthesized <italic>via</italic> a template method using PS spheres as templates and characterized by transmission electron microscopy, scanning electron microscopy, X-ray diffraction and Brunauer–Emmett–Teller analysis.
Effects of Aluminum Particle Size, Galinstan Content and Reaction Temperature on Hydrogen Generation Rate Using Activated Aluminum and Water
Aluminum, in its normal passive oxidized state, does not react with water. In this work, aluminum activation is carried out using liquid metal eutectics Ga-In-Sn-Zn (60:25:10:5). Subsequently, the reaction with water of activated aluminum to produce hydrogen has been examined. The effects of aluminum particle size, li…
