A nano-scaled coating of titanium oxide (TiO 2 ) on graphene (G) has been achieved via a novel atomic layer deposition (ALD) method. As a potential supercapacitor material, the TiO 2 -G composites exhibited a capacity of 75 F/g and 84 F/g at a scan rate of 10 mV/s for composites grown using 50 and 100 ALD cycles, resp…
Oxides and mixed oxides have a tremendous importance in the field of heterogeneous catalysis, serving either as catalysts or as supports for active species. The performance of a catalyst depends directly on its composition, texture, structure and surface properties, which have to be precisely controlled and adapted to…
Chirality is absolutely central in chemistry and biology. The recent findings of chiral self-assembling peptides' remarkable chemical complementarity and structural compatibility make it one of the most inspired designer materials and structures in nanobiotechnology. The emerging field of designer chemistry and biolog…
Stimulated by the recent experimental synthesis of a new layered carbon allotrope-graphdiyne film, we provide the first systematic ab initio investigation of the structural and electronic properties of bilayer and trilayer graphdiyne and explore the possibility of tuning the energy gap via a homogeneous perpendicular…
Graphene oxide was found to be a convenient and efficient supporting material for grafting of oxo-vanadium Schiff basevia covalent attachment. The low dimensionality and rich surface chemistry of graphene oxide play critical roles in order to achieve a good degree of such grafting. Catalytic potential of the so prepar…
Palladium (Pd) nanoparticles were synthesized using protein rich soybean leaf extract based biological process. Reduction of palladium ions by soybean leaf extract was examined by UV-visible spectroscopic technique. It was believed that the proteins and some of the amino acids that are exist in soybean leaf extracts w…
We review the recent progress in the quantitative understanding of light absorption by colloidal semiconductor quantum dots within the framework of the Maxwell-Garnett (MG) effective medium theory. The fundamental quantities used to describe light absorption by dispersed absorbers—intrinsic absorption coefficient, mol…
We report a new phenomenon in which the reversible formation and disruption of a cellulose nano-whisker (CNW) percolation network in an elastomeric thermoplastic polyurethane (TPU) matrix leads to an unprecedentedly rapidly switchable shape-memory effect (SME) that may be activated by water. The materials have been fu…
Nanoparticles probably constitute the largest class of nanomaterials. Nanoparticles of several inorganic materials have been prepared by employing a variety of synthetic strategies. Besides synthesizing nanoparticles, there has been considerable effort to selectively prepare nanoparticles of different shapes. In view…
A simple and efficient approach of preparing copper oxide/reduced graphene oxide (CuO/rGO) nanocomposite has been demonstrated. CuO/rGO nanocomposites were successfully synthesized through a one-step redox reaction between graphene oxide (GO) sheets and cuprous ions in CuCl without extra reducing agent. Notably, the r…
Don't forget poly(disulfide)s. There is a rich literature pointing out the advantages of the dynamic nature of single disulfide bridges to explore self-sorting, biomolecular engineering, biomembrane analysis, and so on. Disulfide bonds between polymer chains are essential for protein folding, materials properties and…
A mononuclear Dy(III) complex with a non-Schiff base compartmental ligand has been prepared and characterised by X-ray crystallography and ac magnetic susceptibility measurements. The complex exhibits SIM behaviour induced by dilution and/or magnetic field with two thermally activated relaxation processes.
A simple microwave assisted route has been formulated to synthesise various surface functionalized carbogenic quantum dots from biodegradable polysaccharides. The photoluminescence (PL) properties of such surface functional carbon quantum dots (CQDs) have been tuned by the in situ addition of high boiling organic solv…
Due to their low thermal conductivity, non-toxicity and low cost, conductive polymer materials are potential candidates for thermoelectric applications. Here, a detailed investigation into the thermoelectric properties of P3HT films is reported. A thermoelectric power factor over 20 μW m−1 K−2 at room temperature was…

The separation of CO₂ from a mixture of CO₂ and N₂ using a porous graphene membrane was investigated using molecular dynamics (MD) simulations. The effects of chemical functionalization of the graphene sheet and pore rim on the gas separation performance of porous graphene membranes were examined. It was found that ch…
One-dimensional (1D) nanostructures, including polymeric, small molecule and inorganic types, are currently being investigated in great detail for their unique mechanical, optical, electronic properties and potential implementation as devices. To integrate 1D nanostructures into device applications, it is of importanc…
Cobalt-free small La3+-doped BaFeO3−δ is synthesized and systematically characterized towards application as an oxygen reduction electrode material for intermediate temperature solid oxide fuel cells (IT-SOFCs) with oxygen-ion conducting electrolyte. The formation of an oxygen vacancy-disordered perovskite oxide with…
A series of six perylene bisimides (PBIs) with hydrophilic and hydrophobic side chains at the imide nitrogens were applied for a comparative study of the solvent and structural effects on the aggregation behaviour of this class of dyes. A comparison of the binding constants in tetrachloromethane at room temperature re…
Three-dimensional (3D) structures of graphene have attracted extensive interest for their practical applications, such as supercapacitors and catalyst supports. Self-assembly is a typical technique to fabricate macroscopic graphene materials integrated with various superior properties. However, an efficient and enviro…
