In this article, the basic principles of core–shell polymers (CSPs) such as definitions, classifications and applications are critically investigated. Introduction of CSPs characterization techniques, such as Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), 1H and 13C Nuclear Magnetic Resona…
This tutorial review aims to present and describe selected examples of still quite rare endo-functionalized supramolecular capsules. Only capsules assembled through the use of neutral or polar hydrogen bonding interactions are covered. The ability of these capsules to orient and control the position of the encapsulate…
Abstract Surfaces and interfaces can significantly influence the overall response of a solid body. Their behavior is well described by continuum theories that endow the surface and interface with their own energetic structures. Such theories are becoming increasingly important when modeling the response of structures…
Since its inception in 1995, significant advances in the field of bulk heterojunction (BHJ) solar cells have been made and polymeric semiconductors are now considered to be one of the most promising ways to lower the cost of the energy generated by solar cells. Power conversion efficiencies (PCEs) are now reaching the…
Developing new methods to improve the photocatalytic activity of graphitic carbon nitride (g-C₃N₄) for hydrogen (H₂) evolution has attracted intensive research interests. Here, we report that the g-C₃N₄ exhibits photocatalytic activity for H₂ evolution from pure water. And, the activity is dramatically improved by loa…
A facile method was used to prepare uniform Au NR/TiO2 and Au/Ag NR/TiO2 core-shell composite nanoparticles. Au/Ag NR/TiO2 nanoparticles were found to display significantly enhanced visible light photo-catalytic activity compared to Au NR/TiO2 and the commercially available TiO2 nanoparticles. The enhancement mechanis…
Zeolitic imidazolate frameworks ZIF-8 and ZIF-67 were prepared from stoichiometric metal and ligand aqueous solutions at room temperature within 10 min. Triblock copolymer and ammonium hydroxide are both essential for the formation of ZIFs. Ammonium hydroxide in the aqueous solution deprotonates 2-methylimidazole, and…
Catalytic carbon dioxide fixation by carbonation of glycerol, trimethylolpropane and pentaerythritol glycidyl ether, followed by curing with citric acid amino amides in the presence of cellulose carbonate, represents an attractive green chemistry route to non-isocyanate polyurethanes (NIPU) and bio-based NIPU composit…
A protocol for the ab initio crystal structure determination of powdered solids at natural isotopic abundance by combining solid-state NMR spectroscopy, crystal structure prediction, and DFT chemical shift calculations was evaluated to determine the crystal structures of four small drug molecules: cocaine, flutamide,…
A Cu-catalyst derived from hydrotalcite precursor was highly selective for the hydrogenation of biomass-derived furfural and levulinic acid. 90% yield of furfuryl alcohol and 51% yield of 2-methylfuran were achieved selectively in the hydrogenation of furfural. 91% yield of γ-valerolactone was achieved in the hydrogen…
The synthesis and characterization of a highly photostable bromo-substituted BODIPY dye (I) fused-ring-expanded with thienopyrrole moieties is reported. The results of MTT assays and flow cytometric analyses in living HeLa cells demonstrate that I has a high singlet oxygen quantum yield (ΦΔ = 0.63) and exhibits photoc…
Ultraviolet (UV) and near infrared (NIR) light-responsive polymeric nanomedicines (e.g., cargo-loaded micelles and vesicles) have increasingly received much attention for their applications in the spatiotemporal and on-demand drug delivery and disease therapy. This UV/NIR-sensitivity is activated via a one-photon and/…
A composite of porous Fe3O4 hollow microspheres/graphene oxide (Fe3O4/GO) has been fabricated through a facile self-assembly approach. Driven by the mutual electrostatic interactions, the amine-functionalized Fe3O4 microspheres prepared by a hydrothermal method and then modified by 3-aminopropyltrimethoxysilane were d…
Highly nitrogen-doped carbon capsules (hN-CCs) have been successfully prepared by using inexpensive melamine and glyoxal as precursors via solvothermal reaction and carbonization. With a great promise for large scale production, the hN-CCs, having large surface area and high-level nitrogen content (N/C atomic ration o…
The luminescence thermochromism properties of two entangled copper(I)-iodide coordination polymers formulated [Cu4I4(dmimpr)2]n (1) and [Cu6I6(dimb)3]n (2) (dmimpr = 1,3-di(2-methyl-imidazol-1-yl)propane, dimb = 1,4-di(imidazol-1-yl)butane) are reported. Upon cooling by liquid nitrogen, their solid-state luminescences…
Heparin is a vital biomolecule in widespread clinical use as an anti-coagulant. Heparin sensors have potential applications in the bedside detection of heparin levels in human blood during surgery, while high-affinity heparin binders may enable the development of effective heparin reversal agents for use in patients o…
The electrochemical dissolution of gold is an intricate topic and even though it has been studied for more than 50 years, its understanding remains rather limited. In the current work, we obtain unique information on gold dissolution by using a setup composed of a micro-electrochemical scanning flow cell (SFC) and ind…
The world is naturally radioactive and approximately 82% of human-absorbed radiation doses, which are out of control, arise from natural sources such as cosmic, terrestrial, and exposure from inhalation or intake radiation sources. In recent years, several international studies have been carried out, which have report…
Flower-like spherical ZnIn2S4 superstructures about 500 nm in diameter composed of ultrathin 2–3 nm thick mesoporous nanosheets were synthesized in several minutes by facile polyol-mediated hot-injection. Due to their higher specific surface area and constituent ultrathin mesoporous nanosheets, the hierarchical ZnIn2S…
The aim of this review is to update and to offer an overview of the investigations that have more recently been made on intermetallics, to highlight their importance for several applications in many areas and to examine topics for future research. The main subject is the application of intermetallics as thermal spray…
