In recent years, striking discoveries have revealed that two-dimensional electron liquids (2DEL) confined at the interface between oxide band-insulators can be engineered to display a high mobility transport. The recognition that only few interfaces appear to suit hosting 2DEL is intriguing and challenges the understa…
Utilizing synergetic effects of different fillers is an important strategy to design and develop high-performance nanocomposites. However, owing to the well-known problems such as dispersion, solution viscosity control, and so on, synergetic enhancement effects are usually offset by the defects induced by fillers in h…
Core–sheath structured conductive nanocomposites were prepared by wrapping a homogenous layer of polypyrrole (PPy) around bacterial cellulose (BC) nanofibers via in situ polymerization of self-assembled pyrrole. By manipulating the ordered core–sheath nanostructure, BC/PPy nanocomposites were achieved and outstanding…
We report the formation of single-crystalline octahedral Au-Ag nanoframes by a modified galvanic replacement reaction. Upon sequential addition of AgNO(3), CuCl, and HAuCl(4) to octadecylamine solution, truncated polyhedral silver nanoparticles formed first and then changed into octahedral Au-Ag nanoframes, without re…
A well-engineered scaffold for regenerative medicine, which is suitable to be translated from the bench to the bedside, combines inspired design, technical innovation and precise craftsmanship. Electrospinning and additive manufacturing are separate approaches to manufacturing scaffolds for a variety of tissue enginee…
Magnetic resonance imaging (MRI) contrast agents are pharmaceuticals used widely in MRI examinations. Gadolinium-based MRI contrast agents (GBCAs) are by far the most commonly used. To date, nine GBCAs have been commercialized for clinical use, primarily indicated in the central nervous system, vasculature, and whole…
Porous covalent–organic materials (COMs) are a fascinating class of nanoporous material with high surface area and diverse pore dimensions, topologies and chemical functionalities. These materials have attracted ever-increasing attention from different field scientists, owing to their potential applications in gas sto…
Abstract Forming solid solutions has long been considered an effective approach for good thermoelectrics because the lattice thermal conductivities are lower than those of the constituent compounds due to phonon scattering from disordered atoms. However, this effect could also be compensated by a reduction in carrier…
Using first-principles calculations, the elastic constants, thermodynamic property and structural phase transition of rhenium diboride under pressure are investigated by means of the pseudopotential plane-waves method, as well as the effect of metallic bond on its hardness. Eight candidate structures of known transiti…
La mayoria de las estructuras de hormigon pretensadas construidas en los ultimos 50 anos han demostrado una excelente durabilidad cuando su construccion se realiza atendiendo las recomendaciones de un buen diseno asi como una buena ejecucion y puesta en obra de la estructura. Este hecho se debe en gran parte al temor…
Penelitian yang telah dilakukan ditujukan untuk memperoleh material gel pemancar cahaya. Material yang telah berhasil disintesis dan dikarakterisasi merupakan cairan ionik dengan kation cis-oleil-imidazolinium dan anion kompleks logam mangan. Material ini berfungsi sebagai elektrolit sekaligus emitter. Pada proses fab…
We show explicitly that two approaches to calculations of RKKY interaction between two magnetic impurities in graphene based on Green's functions: one using coordinate--imaginary time representation, and the other using momentum--frequency representation, give exactly the same results and none of them has to operate w…
En el presente trabajo de tesis doctoral se investiga y confirma la posibilidad de producir polihidroxialkanoatos (PHA), una familia de termoplasticos biodegradables, capaces de sustituir plasticos derivados del petroleo, a partir de diferentes materias primas de origen renovable, empleando diferentes cepas de la bact…
The Ti1.27Fe + 11 wt.% Ni composite synthesized by arc melting and ball milling and its possible use in hydrogen storage were studied. First the intermetallic Ti1.27Fe was obtained from elemental powders of Ti and Fe by using the arc melting in argon atmosphere and was cracked in a reactor, after that nickel powder wa…

Selective generation of an amine-terminated self-assembled monolayer bound to silicon wafers via a silicon-carbon linkage was realized by photocatalytically reducing the corresponding azide-terminated, self-assembled monolayers (Az-SAMs). The Az-SAM was obtained by thermal deposition of 11-chloroundecene onto a hydrog…
Synthesis of a simple fluorescent naphthalimide based receptor 4-aminobenzyl-N-methyl-1,8naphthalimide 3 was carried out as a selective fluoride ion sensor. In acetonitrile, interaction of 3 with different anions such as, AcO -, F -, Cl -, Br -, I -, and SCN -revealed significant fluorescence quenching only with the F…

Abstract Facile synthesis of a new series of π-extended thienoacenes has been described. Their electronic structures have been elucidated by UV–vis absorption and photoelectron spectra. Well-defined single-crystal microribbons composed of self-organized thienoacene molecules have been fabricated using physical vapor t…
Novel acrylated epoxidized hemp oil (AEHO) based bioresins were successfully synthesised, characterized and applied to biocomposites reinforced with woven jute fibre. Characterisation of the synthesised AEHO consisted of acid number titrations and FTIR spectroscopy to assess the success of the acrylation reaction. Thr…
