Amine-functionalized magnetic nanocomposite particles for efficient immobilization of lipase: effects of functional molecule size on properties of the immobilized lipase
(Journal article; Peer reviewed, 2015)A cost-effective design of reusable enzyme-functionalized particles with better catalytic activity is of great scientific interest due to their applications in a wide range of catalytic reactions in several industrial ... -
Chemical stability of Ca3Co4−xO9+δ/CaMnO3−δ p–n junction for oxide-based thermoelectric generators
(Peer reviewed; Journal article, 2020)An all-oxide thermoelectric generator for high-temperature operation depends on a low electrical resistance of the direct p–n junction. Ca3Co4−xO9+δ and CaMnO3−δ exhibit p-type and n-type electronic conductivity, respectively, ... -
Colloid-probe AFM studies of the surface functionality and adsorbed proteins on binary colloidal crystal layers
(Journal article; Peer reviewed, 2017)Colloid-probe-AFM has been widely used to measure the forces of interaction between two surfaces such as particles of different size and functionality or a flat surface and a particle in aqueous environments. However, the ... -
Controlling the self-assembly and optical properties of gold nanoclusters and gold nanoparticles biomineralized with bovine serum albumin
(Journal article; Peer reviewed, 2015)While the size-dependent optical properties of BSA-stabilized gold nanoclusters are well known, the time-dependent growth mechanism remains to be described. Herein, we systematically compare two synthesis methods with and ... -
Electronic and structural properties of the natural dyes curcumin, bixin and indigo
(Peer reviewed; Journal article, 2021)An optical, electronic and structural characterisation of three natural dyes potentially interesting for application in organic solar cells, curcumin (C21H20O6), bixin (C25H30O4) and indigo (C16H10N2O2), was performed. ... -
Improved electrochemical performance and solid electrolyte interphase properties of electrolytes based on lithium bis(fluorosulfonyl)imide for high content silicon anodes
(Journal article; Peer reviewed, 2022)Electrodes containing 60 wt% micron-sized silicon were investigated with electrolytes containing carbonate solvents and either LiPF6 or lithium bis(fluorosulfonyl)imide (LiFSI) salt. The electrodes showed improved performance, ... -
Nanostructured diatom earth SiO2 negative electrodes with superior electrochemical performance for lithium ion batteries
(Peer reviewed; Journal article, 2020)Diatomaceous earth (DE) is a naturally occurring silica source constituted by fossilized remains of diatoms, a type of hard-shelled algae, which exhibits a complex hierarchically nanostructured porous silica network. In ... -
One-step lipase-catalysed preparation of eslicarbazepine
(Peer reviewed; Journal article, 2016)The antiepileptic eslicarbazepine (S-licarbazepine) has been prepared in one step from its racemic form RS-licarbazepine via lipase catalysed kinetic resolution. A novel stereoselective simultaneous HPLC separations of ... -
Preparation of electrocatalysts by reduction of precursors with sodium citrate
(Journal article; Peer reviewed, 2014)In this work synthesis of Pt/C catalysts by reduction of H2PtCl6 with sodium citrate has been investigated. The strong pH-dependence of citrate as a reducing and stabilizing agent has been explored, and an optimum pH range ... -
Silica from diatom frustules as anode material for Li-ion batteries
(Journal article; Peer reviewed, 2019)In spite of its insulating nature, SiO2 may be utilized as active anode material for Li-ion batteries. Synthetic SiO2 will typically require sophisticated synthesis and/or activation procedures in order to obtain a ... -
Structural evolution of water and hydroxyl groups during thermal, mechanical and chemical treatment of high purity natural quartz
(Peer reviewed; Journal article, 2020)Fused silica crucibles are commonly used in the fabrication process of solar grade silicon ingots. These crucibles are manufactured from high purity natural quartz sand and as a consequence, their properties are influenced ... -
The effect of mesoporous silica nanoparticle surface chemistry and concentration on the α-synuclein fibrillation
(Journal article; Peer reviewed, 2015)The aggregation of an amyloid protein, α-synuclein (α-Syn), has been suggested as a potential cause of Parkinson's and several other neurodegenerative diseases. To explore the possibility of using nanoparticle-based ... -
Van der Waals density functional study of the energetics of alkali metal intercalation in graphite
(Journal article; Peer reviewed, 2014)We report on the energetics of intercalation of lithium, sodium and potassium in graphite by density functional theory using recently developed van der Waals (vdW) density functionals. First stage intercalation compounds ...
