We discuss the appearance of odd-frequency spin-triplet $s$-wave superconductivity, first proposed by Berezinskii [J. Exp. Theor. Phys. 20, 287 (1974)], on the surface of a topological insulator proximity coupled to a conventional spin-singlet $s$-wave superconductor. Using both analytical and numerical methods, we sh…
Interest is growing in the use of hydrogels as bone tissue-engineering (TE) scaffolds due to advantages such as injectability and ease of incorporation of active substances such as enzymes. Hydrogels consisting of gellan gum (GG), an inexpensive calcium-crosslinkable polysaccharide, have been applied in cartilage TE.…
In this tutorial article, the recent development of polymer assisted deposition (PAD) for the growth of a wide range of materials, in particular in thin films, is reviewed. Specifically, we describe the unique chemistry and processes of PAD for the deposition of metals, metal-oxides, metal-nitrides, metal-carbides, an…
A ruthenium trichloride complex has been loaded into an aluminium metal-organic framework (MOF), MOF-253, by post-synthetic modification to give MOF-253-Ru. MOF-253 contains open bipyridine sites that are available to bind with the ruthenium complex. MOF-253-Ru was characterised by elemental analysis, N(2) sorption an…
The assembly and isolation of DNA oligonucleotide-functionalized gold nanoparticles (AuNPs) has become a well-developed technology that is based on the strong bonding interactions between gold and thiolated DNA. However, achieving DNA-functionalized semiconductor quantum dots (QDs) that are robust enough to withstand…
Efforts to develop engineered tendons and ligaments have focused on the use of a biomaterial scaffold and a stem cell source. However, the ideal scaffold microenvironment to promote stem cell differentiation and development of organized extracellular matrix is unknown. Through electrospinning, fibre scaffolds can be d…
The present study reports the optimized synthesis, physicochemical characterization, and biological evaluation of a novel, multiwalled carbon nanotube-hyaluronic acid (MWCNT-HA) conjugate, complexed with an anticancer agent, Doxorubicin (DOX) via π-π stacking interaction. The therapeutic conjugate was concomitantly la…
We study the interplay between disorder and interaction in one-dimensional topological superconductors which carry localized Majorana zero-energy states. Using Abelian bosonization and the perturbative renormalization group approach, we obtain the renormalization group flow and the associated scaling dimensions of the…
The chemical bond as a physical linkage between atoms has proven to be an immensely powerful heuristic device, providing insight into the general relationships between the structure and properties of molecules and solids. Unfortunately, the bond concept is incomplete and fails to explain more subtle aspects of molecul…
Abstract Nanoparticles of mesoporous MIL‐100(Al, Cr or Fe) metal–organic frameworks were synthesized by a microwave‐assisted solvothermal route with green solvents. The optimization of yield, crystallinity, and particle size was achieved through the control of synthetic parameters such as temperature, heating rate, an…
Dilute acid as well as water only (hydrothermal) pretreatments often lead to a significant hemicellulose loss to soluble furans and insoluble degradation products, collectively termed as chars and/or pseudo-lignin. In order to understand the factors contributing to reducing sugar yields from pretreated biomass and the…
Green-absorbing dipyrromethene dyes engineered from bis-vinyl-thienyl modules are planar molecules, exhibiting strong absorption in the 713-724 nm range and displaying comparable electron and hole mobilities in thin films (maximum value 1 × 10(-3) cm(2)/(V·s)). Bulk heterojunction solar cells assembled with these dyes…
Self-supported Li(4) Ti(5) O(12) nanowire arrays with high conductivity architectures are designed and fabricated for application in a Li-ion battery. The Li(4) Ti(5) O(12) nanowire arrays grow directly on Ti foil by a facile solution-based method, further enhancing Li-ion storage properties by creating Ti(3+) sites t…
The energy costs associated with separating tightly bound excitons (photoinduced electron-hole pairs) and extracting free charges from highly disordered low-mobility networks represent fundamental losses for many low-cost photovoltaic technologies. We report a low-cost, solution-processable solar cell, based on a high…
We have calculated thermal conductance of graphene nanoribbons (GNRs) and their dependence on the type of ribbon edge termination (zigzag or armchair) and the width of the ribbon, which ranges from 50 Å to 50 μm. Our model incorporates the effect of edge roughness and includes edge roughness correlation functions for…
The structural evolution, stabilities, and electronic properties of copper-doped lithium Li n Cuλ (n = 1–9, λ = 0, −1) clusters have been systematically investigated using a density functional method at PW91PW91 level. Extensive searches for ground-state structures were carried out, and the results showed the copper t…
Due to the importance of the hydrophobic interaction in protein folding, we decided to study the effect of pressure and temperature on the phase transitions of non-polar solutes in water, and thereby their solubility, using molecular dynamics simulations. The main results are: (1) within a certain range, temperature i…
Drug delivery to brain is still a challenging task due to the presence of the blood–brain barrier (BBB), a very restrictive barrier mainly composed of tightly sealed endothelial cells. The anatomy and physiology of BBB strictly regulates the brain access and clearance of endogenous and exogenous molecules from the sys…
The present study involves the development of a carbon nanotube based DNA nanosensor to determine the toxicological behavior of mitoxantrone (MTX). Mitoxantrone intercalates with DNA and produces a MTX-DNA adduct, resulting in the blockade of protein synthesis and excessive production of free radicals in the myocardiu…
Abstract We use coarse‐grained Langevin dynamics simulations of blends of generic conjugated polymers and acceptor molecules to show how architecture (e.g., side chains, backbone flexibility of oligomers) and the pair‐wise interactions between the constituents of the blend affect morphology and phase transition. Alkyl…
