Abstract The emulsion polymerization process was used in the synthesis of polydiphenylamine (PDPA) to obtain new morphologies, and the effects of surfactant types − anionic, cationic, non‐ionic − and surfactant concentrations were investigated with the roles of a template and a dopant. Scanning electron microscopy ima…
This chapter presents traditional and new concepts on the microbially influenced corrosion (MIC) from the microbiological viewpoint. Many review articles on microbially influenced corrosion take the viewpoint of metal destruction. It also investigates corroding iron as a food source for hydrogen-consuming bacteria. So…
This paper reported for the first time a comparative study of the photocatalytic activity of the Keggin-type Mn(II)-substituted heteropolyanion PW 11 O 39 Mn II (H 2 O) 5– (PW 11 Mn) and its heterogeneous system PW 11 Mn/D301R through the degradation of rhodamine B (RhB) under visible light irradiation. A novel photoc…
A series of novel pyrazole-based bis- and tris-amide molecules have been synthesized and characterized which were found to gel copper chloride only among other first row transition metals or other copper salts. All the gels have been thoroughly characterized using infrared spectroscopy, UV–visible spectroscopy, scanni…
Layered hydroxide nanoparticles are generally biocompatible, and less toxic than most inorganic nanoparticles, making them an acceptable alternative drug delivery system. Due to growing concern over animal welfare and the expense of in vivo experiments both the public and the government are interested to find alternat…
Mammalian collagen has been widely used as a biomedical material. Nevertheless, there are still concerns about the variability between preparations, particularly with the possibility that the products may transmit animal-based diseases. Many groups have examined the possible application of bioengineered mammalian coll…
Platinum nanoparticles functionalized with 4-ethynylphenylboronic acid pinacol ester (Pt-EPBAPE) were successfully synthesized by a simple chemical reduction procedure. Because of the formation of conjugated metal-ligand interfacial linkages, the resulting nanoparticles exhibited apparent photoluminescence arising fro…
Chemical functionalization of graphene holds promise for various applications ranging from nanoelectronics to catalysis, drug delivery, and nanoassembly. In many of these applications, it is critical to assess the rates of electromigration-directed motion of adsorbates along the surface of current-carrying graphene du…
Abstract The synthesis and full characterization of three tetrathiafulvalene‐based phenanthroline ligands, namely, N‐(1,10‐phenanthrol‐5‐yl)‐6,7‐(ethylenedithio)tetrathiafulvalene‐2‐carboxamide (1), 2‐[(1,10‐phenanthrol‐5‐yl)aminocarbonylmethylthio]‐3,6,7‐tris(methylsulfanyl)tetrathiafulvalene (2), and 2‐[(1,10‐phenan…
The fabrication of ordered arrays of self‐encapsulated “micro‐bubble” material constructs based on the capillary‐driven collapse of flexible silk fibroin sheets during propagation of the diffusion front of the encapsulated material is demonstrated. The individual micro‐bubbles of different shapes are composed of a sac…
We study the interaction of small hydrophobic particles on the surface of an ultrasoft elastic gel, in which a small amount of elasticity of the medium balances the weights of the particles. The excess energy of the surface of the deformed gel causes them to attract as is the case with the generic capillary interactio…
Abstract New metallic triclinic (1) and monoclinic (2) crystals of the (BEDT‐TTF)4AI[MIII(C2O4)3]G family of organic molecular conductors have been prepared: α‐“pseudo‐κ”‐(BEDT‐TTF)4Kx(H3O)1–x[GaIII(C2O4)3]·1,2‐C6H4Br2 (x ≈ 0.45) (1) and β″‐(BEDT‐TTF)4Kx(H3O)1–x[GaIII(C2O4)3]·PhBr (x ≈ 0.33) (2). The triclinic crystal…
Fifteen substituted maleimide cycloadducts of anthracene derivatives were synthesized in one or two steps from available precursors in yields ranging from 32 to 63%. They differ in the nature of the group on the maleimide nitrogen atom and of the substituents on the anthracene platform. In all instances, the introduct…
Biomimetic composite materials consisting of vanadium pentoxide (V2O5) and a liquid crystal (LC) "gluing" polymer were manufactured exhibiting six structural levels of hierarchy, formed through LC phases. The organic matrix was a polyoxazoline with pendant cholesteryl and carboxyl units, forming a lyotropic phase with…
Crystal growth due to recrystallization in rapidly solidified microstructures was experimentally observed. Deeply undercooled Ni–Cu alloy melts were quenched before rapid solidification by Ga–In liquid alloy. After the quenching, partially recrystallized microstructures were obtained and further investigated by means…
Performing time-tagged, time-correlated, single-photon-counting studies on individual colloidal nanocrystal quantum dots (NQDs), the evolution of photoluminescence (PL) intensity-fluctuation behaviors in near-infrared (NIR) emitting type II, InP/CdS core-shell NQDs is investigated as a function of shell thickness. It…
The electrochemically induced extraction of metal atoms from the ternary layered carbides Ti3AlC2, Ti2AlC, and Ti3SiC2 (MAX phases) at room temperature results in predominantly amorphous carbon with a narrow distribution of micropores, as described by Y. Gogotsi et al. in their Communication on page 4877 ff. This appr…
The α and β-positions of pyrrole were substituted with 3,5-dimethylpyrazolylmethyl groups in a single step that involved the reaction between 2,5-dimethylaminomethylpyrrole and 3,5-dimethylpyrazole-1-carbinol, affording 2,3,4,5-tetrakis(3,5-dimethylpyrazol-1-ylmethyl)pyrrole LH in 40% yield. The coordination chemistry…
A method for situ preparing a hybrid material consisting of silica nanoparticles (SiO2) attached onto the surface of functionalized graphene nanoplatelets (f-GNPs) is proposed. Firstly, polyacrylic acid (PAA) was grafted to the surface of f-GNPs to increase reacting sites, and then 3-aminopropyltriethoxysilane (APTES)…
Macroscopic supramolecular assembly is a promising bottom-up method to construct ordered three-dimensional structures in a programmable way because of its flexible tailoring features. To handle the challenges of precisely aligning the building blocks, we proposed the combination of magnetic field-assisted localization…
