Epitaxially grown heterogeneous nanowires present dislocations at the interface between the phases if their radius is big. We consider a corresponding variational discrete model with quadratic pairwise atomic interaction energy. By employing the notion of Gamma-convergence and a geometric rigidity estimate, we perform…
A hybrid epoxy resin with intrinsic self healing properties has been prepared from a bifunctional Diels-Alder (DA) adduct. The obtained network, based on conventional Diglycidyl ether of BisphenolA (DGEBA) and DA epoxy, leads to simultaneous tuning of physical-chemical properties and healing capability. The self-repai…
The influence of the polymer length and the valency of guest-modified poly(ethylene glycol) (PEG) on the stability, size tunability and formation dynamics of supramolecular nanoparticles (SNPs) has been studied. SNPs were formed by molecular recognition between multi- and monovalent supramolecular building blocks with…
This feature paper reviews our recent efforts to theoretically model the effect of polymer mediated interactions on the coagulation-fragmentation of nano-colloids in different settings encountered in practical systems. The polymer-mediated interactions among nanoparticles play a key role in many biological and technol…
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 sp 2 + sp 1 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 gr…
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 <sub>2</sub> O <sub>4</sub> :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( <italic>N</italic> -vinylimidazole)- <italic>l-</italic> poly(tetrahydrofuran) amphiphilic conetworks were investigated by thermogravimetric analysis and thermogravimetry-mass spectrometry.
