Hydrogel constructs were rapidly fabricated via the electrophoretic adhesion of oppositely charged microbeads. The reversible preparation of hydrogel constructs was achieved by the reconstruction of microbead networks.
A zinc oxide (ZnO) nanoparticle photodetector was fabricated using a simple method. Under a 5 V applied bias, its dark current and photocurrent were 1.98 × 10 −8 and 9.42 × 10 −7 A, respectively. In other words, a photocurrent‐to‐dark‐current contrast ratio of 48 was obtained. Under incident light at a wavelength of 3…
Carbonyl complexes of transition metals (Mx(CO)y, where x = 1, 2, or 3 and y = 6, 10, or 12 for M = W, Re, or Os, respectively) inserted into single walled carbon nanotubes (SWNT, diameter 1.5 nm) transform into metallic nanoparticles (MNPs) under heat treatment or electron beam irradiation. The host-nanotube acts as…
We develop a simple dry wrapping method to fabricate a tungsten oxide (WO(3))/carbon nanotube (CNT) cable, in which WO(3) layers act as an electrochromic component while aligned CNTs as the core provide mechanical support and an anisotropic, continuous electron transport pathway. Interestingly, the resultant cable mat…
Novel boron dipyrromethene (BODIPY) derivatives having significant absorption and emission in the longer wavelength region were synthesized. BODIPY showed anomalous S(2) emission from the second excited (S(2)) state at shorter wavelength. The photodynamics of the S(2) state was investigated by fluorescence up-conversi…
This report demonstrates how typical particle morphologies documented in biomimetic mineralization studies of calcium carbonate will precipitate also from solutions without adding modulating additives, at supersaturation levels below the solubility level of amorphous calcium carbonate (ACC). In the literature, hexagon…
Metal oxide nanowires are promising building blocks for thin film transistors due to their one-dimensional geometry in nanoscale, high crystalline nature, and excellent optical and electrical properties. In the past decade, intensive research interest has been drawn to metal oxide nanowire transistors, and various met…
Both the structure and dynamics of biomolecules are known to be essential for their biological function. In the dehydrated state, the function of biomolecules, such as proteins, is severely impeded, so hydration is required for bioactivity. The dynamics of the hydrated biomolecules and their hydration water are relate…
Hierarchical porous carbide-derived carbon monoliths (HPCDCM) were prepared by selective extraction of silicon from ordered mesoporous silicon carbide monoliths (OMSCM) through chlorination at high temperature. The OMSCM was firstly synthesized by pressure-assisted nanocasting procedure using KIT-6 silica as the hard…
We report the fabrication and characterization of an electrochemically synthesized polycarbazole–organically modified nanoclay composite-based organic Schottky diode. The morphology of the nanocomposite is studied using scanning electron microscopy and high resolution transmission electron microscopy images, before fa…
Bioinspired fibers with multi-gradient and multi-scale spindle knots are artfully fabricated via combining a dip-coating technique and a water droplet templating method. Due to the effective cooperation of multi-gradient and multi-scale spindle knots, the bioinspired fiber achieves a much stronger water-hanging abilit…
Because of their multifunctionality and unique magnetic properties, superparamagnetic iron oxide nanoparticles (SPIONs) have been recognized as very promising materials for various biomedical applications. The main difficulty with the use of SPIONs as multimodal bioimaging agents is their lack of fluorescence. Since c…
Electrical and thermal transport properties of quasicrystals are reviewed on the examples of i-Ag-In-Yb and i-Al-Cu-Fe icosahedral phases and d-Al-Co-Ni decagonal phase. Using samples of single-grain morphology and high structural quality, and performing the measurements along well-defined crystallographic directions,…
Self-assembly holds promise for creating new materials and devices because of its inherent parallelism, allowing many building blocks to simultaneously organize using preprogrammed interactions. An important trend in nanoparticle and colloid science is the synthesis of particles with unusual shapes and/or directional…
We investigated WS2–multiwalled carbon nanotube composites prepared by powder metallurgy. The inclusion of a small amount of nanotubes (0.75 wt%) dramatically increased electrical conductivity (by 12 300%) with a moderate decrease in the Seebeck coefficient (by 22%) and thermal conductivity (by 43%) enhancing both pow…
Fmoc-protected amino acid based (Fmoc-Phe-OH) hydrogel has been developed in our laboratory previously (S. Roy and A. Banerjee, Soft Matter, 2011, 7, 5300–5308). This hydrogel has been used to incorporate and disperse functionalized single-walled carbon nanotube (f-SWCNT) within the gel phase to make a hybrid hydrogel…
A structured catalyst has been fabricated by immobilizing cobalt phthalocyanine tetrasulfonate (CoPcS) on a mixed metal oxide (denoted as MMO) film, which exhibits excellent activity, stability and recyclability for mercaptan sweetening. Scanning electron microscopy (SEM) images show that the structured catalyst is co…
A hydrogen bonded heme-Fe(III)-O(2)(-) adduct is stabilized and characterized using resonance Raman and EPR spectroscopy. The low O-O vibrations of this complex are quite different from those reported for other heme-Fe(III)-O(2)(-) adducts.
Three hybrid networks based on octamolybdate building units, Cu(I)(8)BBTZ(6)[(α-Mo(8)O(26))(β-Mo(8)O(26))] (1), (Cu(I)BBTZ)(4)[Mo(7)Cu(II)O(24)(H(2)O)(2)]·6H(2)O (2), and Cu(II)Cu(I)(2)BBTZ(5)[β-Mo(8)O(26)] (3) (BBTZ = 1,4-bis(1,2,4-triazol-1-ylmethyl)benzene), have been synthesized under ionothermal conditions and st…
The incorporation of trityl and triphenylsilyl groups into low molecular weight molecules allows the formation of stable molecular glasses. A series of materials based on the N-phenyldiethanolamine core was synthesized bearing different azobenzenes and benzylydene-1,3-indandione as active chromophores. Molecular hyper…
