Well-intergrown ZIF-8 membranes are prepared by using zinc hydroxide nanostrands as the unique zinc source in benign solvent at room temperature and exhibit very fast H 2 permeability and high selectivity for gas separation after secondary growth.
A novel electrochemical cytosensor was developed for the fast and high-sensitivity recognition of drug-resistant leukemia K562/ADM cells based on the P-glycoprotein (P-gp) expression level on a cell membrane. The nanocomposite interface of the gold nanoparticles/polyaniline nanofibers (AuNPs/PANI-NF) was chosen to des…
A new thiacalix[4]arene-fluorescein based fluorescent probe was synthesized, which shows a turn-on fluorescence response in the presence of CN(-) ions attributed to the nucleophilic addition of cyanide ions and the resulting cyanide adduct was used for the selective detection of copper ions. Furthermore, based on the…
The OLED devices fabricated using two novel indolo[3,2- b ]carbazole derivatives containing dimesitylboron groups as electroluminescent materials show reasonably good performance.
Abstract In this work, we report on high‐performance bottom‐gate top‐contact (BGTC) amorphous‐Indium‐Gallium‐Zinc‐Oxide (a‐IGZO) thin‐film transistor (TFT) with SiO2 as an etch‐stop‐layer (ESL) deposited by medium frequency physical vapor deposition (mf‐PVD). The TFTs show field‐effect mobility (μFE) of 16.0 cm2/(V.s)…
The European Commission's Joint Research Centre (JRC) provides scientific support to European Union (EU) policy regarding nanotechnology. Within this context, the European Commission’s Joint Research Centre launched, in February 2011, a repository for Representative Test Materials (RTMs), based on preparatory work sta…
We present a new way to enhance the electron-phonon coupling constant and the critical superconducting temperature of graphene, significantly beyond all reported values. Using density functional theory, we explore the application effects of the tensile biaxial strain on the lithium intercalated graphene. Both effects…
Abstract Synthesis of poly(vinyl chloride-graft-2-vinylpyridine) graft copolymers was carried out by reversible addition-fragmentation chain transfer (RAFT) polymerization of 2-vinylpyridine using a novel macroinitiator (RAFT macroinitiator). For this purpose, RAFT macroinitiator was obtained from the potassium salt o…
In this study, rice straw was pretreated by an ionic liquid, 1-ethyl-3-methylimidazolium acetate ((EMIM)(OAc)), prior to enzymatic hydrolysis and ethanol production. The pretreatment was carried out at 120 °C for 5 h under atmospheric pressure. Afterward, saccharification was conducted at 45 °C for 72 h using 20 FPU c…
PURPOSE: The surface integrity associated with implant placement was examined to determine whether the topography of common implant surface modifications is retained after implant insertion. MATERIALS AND METHODS: Turned (TU), acid-etched (AE), and anodized (AN) experimental implants prepared in-house were inserted in…
This paper gives an overview of OpenMC, an open source Monte Carlo particle transport code recently developed at the Massachusetts Institute of Technology. OpenMC uses continuous-energy cross sections and a constructive solid geometry representation, enabling high-fidelity modeling of nuclear reactors and other system…
Skeletal muscle has good regenerative capacity, but the extent of muscle injury and the developed fibrosis might prevent complete regeneration. The in vivo application of human mesenchymal stem cells (HMSCs) of the umbilical cord and the conditioned media (CM) where the HMSCs were cultured and expanded, associated wit…
Peptides present a low cost and environmentally friendly route to facilitate the fabrication of organic solar cells.
A naphthalimide-based azo dye (1) used as a colorimetric and ratiometric probe for the detection of CN− was synthesized by incorporating a salicylaldehyde moiety, which acts as a recognition unit, to the naphthalimido diazonium salt. Upon reacting with CN−, probe 1 displays dramatic colour changes rapidly from yellowi…
A new water-soluble pillar[6]arene was successfully prepared. It complexed with a sodium p-hydroxybenzoate derivative to form a supra-amphiphile. The controllable self-assembly and application in controlled release of this supra-amphiphile in water were investigated.
Cationic gemini surfactants have strong potential as compaction agents of nucleic acids for efficient non-viral gene delivery. In this work, we present the aggregation behavior of three novel cationic serine-based gemini surfactants as well as their ability to compact DNA per se and mixed with a helper lipid, 1,2-diol…
Two new monoclinic BiPO 4 nanodendrites were for the first time hydrothermally synthesized in the presence of ethylenediamine-tetraacetic acid.
Inspired by bio-adhesive ability of marine mussel, a versatile and effective synthesis strategy was developed to prepare dense zeolite LTA membranes.
We have studied the photoluminescence (PL) properties of [n]cycloparaphenylenes ([n]CPPs), which have simple string structures consisting of varying numbers of benzene rings, using steady-state and time-resolved PL spectroscopy. The PL lifetime decreased dramatically as the number of benzene rings increased, and incre…
Petrographic studies on the intrusive rocks from the Ishiagu area show that they are gabbro, dolerites, and diorite. The gabbro and diorite occur as stocks while the dolerites occur as sills in folded sedimentary sequence predominated by shale. Geochemical data confirmed the rocks as basic (gabbro and dolerites) and i…
