On page 96, C.-F. Chen, Y. Wang, and co-workers demonstrate how electrical breakdown of the metallic pathways in double-walled carbon nanotubes yields high-performance thin-film transistors with simultaneous high ON-state conductance and high ON/OFF ratios.
Hydrogen uptake during the mechanochemistry of lithium nitride under 9 MPa hydrogen pressure has been analyzed by means of in situ solid-gas absorption and ex situ X-ray diffraction (XRD) measurements. In situ hydrogenation curves show two H-sorption steps leading to an overall hydrogen uptake of 9.8 wt% H after 3 hou…
Graphyne, a novel carbon allotrope, is a two-dimensional lattice of sp2+ sp1 hybridization-type carbon atoms, similar to graphene. The initiation and development of wrinkles in single-layer graphynes ( α-, β-, γ-, and 6, 6, 12-graphyne) subjected to in-plane circular shearing are investigated. In comparison with graph…
Three-dimensional (3D) ZnO porous films composed of an interconnected skeleton were fabricated successfully through atomic layer deposition method using carbon nanoparticles as template.
The study of conducting polymers (CPs) is of high current interest due to their wide application in a range of optical and electronic devices. Poly(3,4-Ethylenedioxythiophene)-Poly(Styrene Sulfonate) (PEDOT:PSS) is considered one of the most electrochemically and thermally stable CPs currently available. In many appli…
Poly(dimethylsiloxane) (PDMS) surface was patterned by poly(2-methacryloyloxyethyl phosphorylcholine) (PMPC)-containing photo-crosslinking diblock copolymers upon photo-irradiation.
Photoreactive gold nanoparticles (NP) can be encoded in a spatially resolved fashion using direct laser writing techniques into variable patterns. The surface of the gold nanoparticles is imparted with photoreactivity by tethering photo-caged dienes ('photoenols'), which are able to undergo a rapid Diels-Alder cycload…
The purpose of this work is a detailed comparison of the fundamental magnetic properties of nanocomposite systems consisting of Fe3O4 nanoparticle-loaded porous silicon as well as silicon nanotubes. Such composite structures are of potential merit in the area of magnetically guided drug delivery. For magnetic systems…
We incorporated carbon dots (CDs) into a SrAl 2 O 4 :Eu,Dy phosphor (SAO), and made use of the dual emission from the CDs and SAO within such a composite to realize ratiometric temperature sensing from 100 to 400 K.
Modified amorphous GeTe was analyzed in terms of variations in the local bonding structure. Inducstion of intermediated Ge–Te bonding in modified structure critically affects the phase change process.
We report the investigation of response time of spin resolved electron traversing through a magnetic Co-graphene nano-device. For this purpose, we calculate the transient current under a step-like upward pulse for this system from first principles using non-equilibrium Green's function (NEGF) formalism within the fram…
An economic and low toxicity gold plating process for bio-compatible device fabrication was investigated. A tiopronin-gold complex altered by mercaptothiodiazole or mercaptotriazole derivatives gave a form of the complex that could be reduced autocatalytically to enable electroless gold plating. Catalytic ca. 5 nm gol…
Electron and ion conducting polymer film prepared by hydroiodic acid catalyzed dehydration of poly(vinyl alcohol) and 1-propyl-3-methylimidazolium iodide blend.
Both a Meisenheimer complex and deprotonated TNT are formed when TNT meets amino acid-capped quantum dots.
The study on the quantum dot quantum well (QDQW) microstructure modified by choosing different ligands containing a sulfhydryl group is of significance because it enables one to regulate photoexcited free charge carriers' (FCCs') transport behaviours in high-quality CdTe/ligand QDs via a self-assembled way. The photoe…
The underlying chemical processes of the unexpected thermal decomposition behavior of poly( N -vinylimidazole)- l- poly(tetrahydrofuran) amphiphilic conetworks were investigated by thermogravimetric analysis and thermogravimetry-mass spectrometry.
The twelve-membered tetraazamacrocyclic ligand L1 bears an appended lipoic acid unit, whose disulphide ring is an efficient grafting moiety for the surface of gold nanostars (GNS). The GNS that were used featured a localized surface plasmon resonance (LSPR) absorption at ∼800 nm, i.e. in the near infrared (NIR). We in…
The delivery of chemotherapeutics into tumor cells is a fundamental knot for tumor-target therapy to improve the curative effect and avoid side effects. Here, A54 peptide-functionalized poly(lactic-co-glycolic acid)-grafted dextran (A54-Dex-PLGA) was synthesized. The synthesized A54-Dex-PLGA self-assembled to form mic…
The relaxor ferroelectric K(0.5)Bi(0.5)TiO(3) has been synthesised in a solid-solution series with K(0.5)Bi(0.5)ZrO(3), as K(0.5)Bi(0.5)Ti1-xZrxO(3). High-resolution synchrotron X-ray powder diffraction and X-ray absorption near edge structure spectroscopy were used to characterise the long-range average and local str…
This study investigated high-cycle fatigue behavior in three β-Ti wires (TMA, Resolve, Gummetal). Fatigue was evaluated using a static three-point bending test and a high-cycle fatigue test with a three-point bending mode. The surfaces of fractured wires were observed with scanning electron microscopy, and the post-fa…
