Nonmesogenic cyclic oligoethylene oxide terephthalate is directly connected to flexible polyethylene main chain at every second carbon atom via the phenyl ring to obtain a novel vinyl polymer, poly(cyclic oligoethylene oxide vinylterephthalate) (PEOT-n), where n (= 4–6) denotes the number of ethylene oxide groups in t…
Al2O3 deposited by atomic layer deposition (ALD) is known to provide an excellent passivation on lowly- and highly-doped p-type silicon surfaces even after contact firing processes. Therefore, Al2O3 layers are of great interest for the passivation of the rear side of p-type solar cells as well as the boron-doped emitt…
Thin-film pseudocapacitor electrodes with ultrafast lithium storage kinetics, high capacitance and excellent cycling stability were fabricated from monodispersed TiO(2) building nanocrystals, providing a novel approach towards next-generation micro-supercapacitor applications.
Background and methods: Following exposure via a number of routes (inhalation, ingestion or injection), some Nanomaterials (NMs) translocate to secondary tissues, prominently the liver. This study investigated the effects of an array of NMs, varying in their physicochemical characteristics, consisting of two types of…
A doubly 2,6-pyridylene-bridged porphyrin-perylene-porphyrin triad was synthesized via Suzuki-Miyaura cross coupling reaction, which captures a tetrakis(3-pyridyl)porphyrin guest in a 2 : 1 manner to form a supramolecular complex that undergoes photo-induced electron transfer.
Since the physical properties of electronic and biological molecules strongly depend on the nature of molecular self-assembly and organization, it is essential to control their molecular packing structure and morphology on the different length scales. In this aspect, a programmed amphiphilic tetrathiafulvalene (TTF) m…
BACKGROUND: Structure-based drug design (SBDD) can accelerate inhibitor lead design and optimization, and efficient methods including protein purification, characterization, crystallization, and high-resolution diffraction are all needed for rapid, iterative structure determination. Janus kinases are important targets…
Two 3D coordination polymers of Mn(II) with azide and bifunctional zwitterionic ligands bearing both carboxylate and tetrazolate groups, 1-(carboxylatomethyl)-3-(5-tetrazolato)pyridinium (L(1)) and 1-(carboxylatoethyl)-4-(5-tetrazolato)pyridinium (L(2)), were synthesized, and structurally and magnetically characterize…
visualization of the labeled cells, some critical elements for cell tracking studies are often incompletely characterized, which makes it difficult to validate and meta-analyze the data generated from different studies. Incomplete information on preclinical studies also slows the transition of the findings to clinical…
Ultrafast transient absorption spectroscopy is used to investigate the exciton dynamics of Type II ZnTe-ZnSe core-shell colloidal quantum dots. Surface-trapping is shown to occur within a few picosecond for hot electrons and with a few 10s of picoseconds for electrons cooled to the band-edge, and is the dominant proce…
A zirconia coated column was prepared for capillary electrophoresis separation based on a mussel adhesive protein inspired polydopamine coating for the first time. Polydopamine, formed by the spontaneous oxidative polymerization of dopamine under alkaline conditions, was used to immobilize zirconia onto the inner surf…
This paper depicts the processing and mechanical characterization of a new class of multiphase biocomposites consisting of epoxy resin reinforced with glass fiber and filled with rice husk particulates. In this work, the rice husk is used as a filler material. The effects of incorporation of rice husk in modifying the…
CuInS2 (CIS) was deposited on ZnO nanowires by a chemical spray pyrolysis (CSP) method, resulting in an ultra-thin, conformal CIS coating on ZnO forming ZnO–CIS core–shell structures. A high-resolution transmission electron microscope and elemental mapping showed the excellent quality of the coating, while Raman spect…
Abstract Soda–lime silicate glasses are composition used recently in container, table ware, float glass, etc. Most of soda-lime silicate glasses are produced by major component sand (silica, SiO2), soda ash (Na2CO3) and lime stone (CaCO3) by adding effective minor additive such as dolomite (CaMg(CO3)2), sodium sulfate…
Simply mixing layered rare-earth hydroxide colloidal solutions and paratungstate solution at pH > 7 led to directional self-assembly of rare-earth hydroxide nanosheets and paradodecatungstates. These hybrids exhibit efficient energy transfer from the OMCT band to rare-earth ions in the hydroxide layers as well as high…
Nanoporous silicate materials, produced using an evaporation-induced self-assembly (EISA) approach, are highly effective catalysts for transacetalization reactions. Both acyclic acetals and ketals undergo rapid exchange in the presence of low loadings of nanoporous aluminosilicate materials and diols and triols to gen…
Development of responsive surfaces with switchable hydrophobicity is hindered by their limited mechanical stability. Herein, to address this problem, we fabricated a mechanically durable responsive surface of CNTs/polyethylene composite coating by a facile route. Superhydrophobic CNTs/polyethylene composite coating wa…
This paper presents experimental and theoretical results concerning the corrosion inhibitor effect of imidazole and five of its derivatives on iron surface. Gravimetric methods and polarization curves were the experimental techniques used in this study. The polarization curves showed that the inhibitors have an anodic…
Hydrogels based on segmented PLAaPEGbPLAa triblock copolymers have been extensively researched for biomedical applications, largely for drug delivery and tissue engineering applications, due in particular to the ability to tune their rate of degradation. By copolymerizing acrylated PLAaPEGbPLAa with acrylated Boltorn-…
Aza-crown ether acridinedione-functionalized quantum dots (ACEADD-QDs) and aza-crown ether acridinedione-functionalized gold nanorods (ACEADD-GNRs) have been developed as a pair for a fluorescent chemosensor detecting metal ions. The ACEADD-QDs have dual emissions at a visible wavelength of ∼430 nm from the acridinedi…
