Cellular uptake is a crucial process in nanomedicine and drug-delivery; however, the factors that affect its efficiency/speed are not well understood. We report computer simulations on passive uptake via receptor-mediated endocytosis of nanoparticle coated with ligands. In particular, we study how the distribution of…
Nano-sized dispersive hexagonal magnesium hydroxide (Mg(OH)2) was prepared by an ammonia-hydrothermal method. To improve the crystalline and dispersivity of magnesium hydroxide, citric acid was introduced into the reaction system at ammonia precipitation process and monoethanolamine (MEA) was introduced at hydrotherma…
Epoxidized natural rubber-graphene (ENR-GE) composites with segregated GE networks were successfully fabricated using the latex mixing combined in situ reduced technology. The rheological behavior and electrical conductivity of ENR-GE composites were investigated. At low frequencies, the storage modulus (G') became fr…
Lanthanide doped upconversion nanoparticles grafted with a photocaged analog of doxorubicin allow near IR-release of doxorubicin.
We report the finding of a bowl-shaped quasi-planar structure of a B84 cluster with four hexagonal holes and a three-chain ring all around the edges using ab initio calculations. A large number of other isomers including those explored earlier such as an empty cage, a filled cage, and a disordered structure, have been…
Highly cross-linked and fluorescent polyphosphazene nanoparticles with excellent biocompatibility and improved resistance to photobleaching and protein interference were prepared for cell imaging.
A new methodology for a stimuli-responsive polymer was proposed on the basis of cyclization and photocleavage. This requires only a single reaction per polymer molecule.
Multifunctional optical diffusers based on hybrid polysiloxane@CeO <sub>2</sub> @PMMA microspheres were successfully prepared by UV curing process.
We use in situ synchrotron small- and wide-angle X-ray scattering (SAXS/WAXS) to demonstrate that the formation of crystalline siderite (FeCO(3)) during the corrosion of steel in CO(2)-saturated brine - a problem of practical interest relating to the growth of protective scales on the interior surface of oil and gas p…
The present study examines the influence of the hydrophilic-lipophilic environment, mediated by small molecules, on the structural changes in silk protein fibroin. Small molecules mediate the various hydrophilic-lipophilic balances (HLBs) that impact the organisation of silk protein chains. Changes in the silk fibroin…
DFT and experimental studies on La <sub>x</sub> Sr <sub>1−x</sub> MnO <sub>3</sub> perovskite materials show that a Mn-terminated surface with Sr-doping displays good performance in NSR technology.
Acid functionalized MWCNTs/PC composites showed significant improvement in storage modulus upto 57% in glassy and 400% in rubbery region over pure polycarbonate.
Morphology and sensor responses.
The electronic properties of hydrofluorinated graphene nanosheets can be efficiently modified by interlayer C–H⋯F–C hydrogen bonding.
We have investigated the electronic structures and carrier mobilities of MoS2 monolayer sheets and armchair nanoribbons with chemical modification using the density functional theory combined with the Boltzmann transport method with relaxation time approximation. It is shown that the hole mobility (96.62 cm(2) V(-1) s…
Regenerated bacterial cellulose scaffolds were synthesized through solvent casting and particulate leaching method for application in <italic>in vitro</italic> tissue regeneration.
In the present work the third order nonlinear optical response of a series of pyrazoline derivatives has been experimentally investigated.
NIR absorbing copolymers based on α,β-unsubstituted BODIPY dyes suitable for NIR organic photovoltaics.
A novel negative electrode material of 3D irregular ellipsoidal VO <sub>2</sub> with excellent pseudocapacitive properties is synthesized <italic>via</italic> a simple heat treatment method.
The interfaces between different materials in the heterojunction colloidal quantum dot (QD) solar cell play an important role for charge carrier separation, recombination and collection.
