A novel quantification approach for tissue imaging using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) based on tissue embedding in cold-curing resins (Technovit 7100) is presented. With respect to massive side effects on cisplatin, the platinum distribution at different time intervals after…
Antifouling and antibacterial membranes are prepared by selective surface modification of pH responsive polystyrene-b-poly(4-vinylpyridine) (PS-P4VP) diblock copolymers by quaternization and zwitterionization reactions on a P4VP moiety. Nanoporous membranes based on the self-assembly of 2-(4'-hydroxybenzeneazo) benzoi…
The silver nanoparticles synthesized biologically have been widely used in medicinal field. The synthesis of silver nanoparticles has been carried out by using the extracellular filtrate of the fungal strain, Aspergillus foetidus MTCC8876. The synthesis of silver nanoparticles was identified primarily by changing the…

Complexation of iminocoumarin derivatives with BF3·OEt2 provides novel N^N boron(III) dyes exhibiting high absorption coefficients and quantum yields as great as 81%. The excellent chemical stability of these dyes enables the grafting of Boranil or Bodipy units to give derivatives in which the Borico subunit can act e…
Well-defined amphiphilic poly(ethylene glycol) and poly(dehydroabietic ethyl methacrylate) block copolymers (PEG-b-PDAEMA) were prepared by atom transfer radical polymerization. The methacrylate block contains a characteristic hydrophobic, biocompatible and economical dehydroabietic moiety. PEG-b-PDAEMA block copolyme…
A series of aluminum alkyl complexes nacnacRAlMe2 (2a-2h) bearing aliphatic N-substituted β-diketiminate ligands (nacnacRH = N,N'-dialkyl-2-amino-4-iminopent-2-enes), were prepared from the reaction of trialkyl aluminum and the corresponding β-diketimines. All these aluminum complexes were characterized by NMR, elemen…
Trees and other woody plants are hierarchically structured to achieve a wide range of mechanical properties—necessary for their survival under various and varying loading conditions—with a narrow range of chemical composition. The hierarchical level understood to be directly responsible for modulating the longitudinal…
Surface-enhanced Raman spectroscopy (SERS) is an experimental tool for accessing vibrational and chemical information, down to the single molecule level. SERS typically relies on plasmon excitations in metal nanostructures to concentrate the incident radiation and to provide an enhanced photon density of states to cou…
Currently, one of the biggest challenges in the field of pseudocapacitors is their capacitance value. Current knowledge on improving specific capacitance values is mainly focused on the synthesis of electrode materials with different structures and sizes. However, no studies have addressed using soluble inorganic salt…
A series of thermo-responsive “hairy-rod” polypeptides was efficiently synthesized by grafting of azide-terminated (co)polymers of 2-(2-methoxyethoxy)ethyl methacrylate (MEO2MA) or 2-(2-(2-methoxyethoxy)ethoxy)ethyl methacrylate (MEO3MA) (i.e., N3-PMEOiMA) onto poly(γ-propargyl-L-glutamate) (PPLG) through a “click” re…
Three π-electron rich fluorescent supramolecular polymers (1–3) have been synthesized incorporating 2-methyl-3-butyn-2-ol groups in reasonable yield by employing Sonagashira coupling. They were characterized by multinuclear NMR (1H, 13C), ESI-MS and single crystal X-ray diffraction analyses [1 = 1-(2-methyl-3-butyn-2-…
The interaction between the plenary Keggin H3PW12O40, lacunary Keggin K7PW11O39 and the Eu(III)-substituted Keggin K4EuPW11O39 (Eu-Keggin) type polyoxometalates (POMs), and the proteins human and bovine serum albumin (HSA and BSA) was studied using steady state and time-resolved Eu(III) luminescence and tryptophan (Tr…
A composite electrode consisting of hybrid nanonet/nanoflower NiO deposited on carbon fiber paper scaffolds demonstrates a much-improved areal capacitance (0.93 F cm−2) while maintaining high rate capability and excellent cycling life. These performance characteristics are attributed to the unique electrode architectu…
Block copolymers with metals confined in one or more blocks are emerging as candidate materials for nanomanufacturing applications due to their unprecedented nanoscale pattern transfer capabilities. In this article we highlight recent developments in metal-containing block copolymers in terms of their novel synthetic…
Here we report a suite of approaches for the isolation of asymmetrically grafted organic–inorganic hybrid Mn–Anderson polyoxometalate compounds (TBA)3[MnMo6O18((OCH2)3CNHR1)((OCH2)3CNHR2)] (where TBA = tetrabutylammonium). Both a “pre-functionalization” route (for compound 1 – R1 = –COC14H9, R2 = –H) using two differe…
Rare-earth phosphors with tunable optical properties are used in display panels and fluorescent lamps and have potential applications in lasers and bioimaging. This work reported the preparation, structure and photoluminescence of the unilamellar nanosheets containing Tb3+/Eu3+ delaminated from layered rare-earth hydr…
Sulfur-containing glycodendrimers have steadily emerged over a few decades and this review describes the first survey of this field. Although the contribution of sulfur chemistry to glycodendrimers could be seen at the moment as a development of various linking strategies, there is more than synthesis because the pres…
A very simple and versatile polymer assembly approach was developed. We use methoxy-mercapto-poly(ethylene glycol) (mPEG-SH) to conjugate multiple Au shapes to form dense Au monolayer films (MLFs) with 5 nm gaps and generate gigantic enhancement. The results of the discrete dipole approximation (DDA) method to calcula…
The performance of pseudocapacitors usually depends largely on careful manipulation of nano-architectures and suitable composition of the active materials. Herein, NiTi layered double hydroxide (LDH) thin films with uniform density were synthesized by a process including two hydrothermal treatment steps and the compos…
