We have studied the response of ferromagnetic liquid crystals to external magnetic and electric fields, and compared it to the usual response of nematic liquid crystals (NLCs). We have observed effects, which are not present in a pure NLC and are a consequence of the coupling between the nematic director and the magne…
The thermoelectric performance of poly(3,4-ethylenedioxythiophene) complexed with a poly(4-styrenesulfonic acid) (PEDOT:PSS) film was enhanced by a three-step process.
The lanthanide(iii) cyanoacetate complexes of the formula {[Ln2(CNCH2COO)6(H2O)4]·2H2O}n, where Ln = Eu (), Gd (), Nd (), have been prepared and characterized by X-ray diffraction analysis. Complexes and are isostructural and differ from the binding scheme of the neodymium compound , structurally described earlier. In…
Co <sub>9</sub> S <sub>8</sub> /graphene nanocomposites (Co <sub>9</sub> S <sub>8</sub> /G) at various concentrations of graphene and Co <sub>9</sub> S <sub>8</sub> were prepared and tested for its electrochemical behaviour for supercapacitors.
We designed a perfluorinated dopamine derivative, which, upon oxidative polymerization, formed a structurally rough film of extremely low surface energy on various substrates. The static water contact angles larger than 150° and the low water sliding angles less than 7° confirmed the formation of superhydrophobic, sel…
Poly(vinylidene fluoride) microparticles with diameters between 0.80 and 5.50 μm were produced. Cell viability shows their suitability for tissue engineering.
Infection is the major reason for GTR/GBR membrane failure in clinical applications. In this work, we developed GTR/GBR membranes with localized drug delivery function to prevent infection. Hierarchical membranes containing micro- and nano-fibers were fabricated. The effects of the incorporation of gelatin and loading…
A solid-state high performance flexible asymmetric supercapacitor (ASC) was fabricated. Its anode is based on organic-inorganic materials, where polypyrrole (PPy) is uniformly wrapped on MnO2 nanoflowers grown on carbon cloth (CC), and its cathode is made of activated carbon (AC) on CC. The ASC has an areal capacitanc…
The evolution of copper-based interconnects requires the realization of an ultrathin diffusion barrier layer between the Cu interconnect and insulating layers. The present work reports the use of atomically thin layer graphene as a diffusion barrier to Cu metallization. The diffusion barrier performance is investigate…
Chemical speciation of heavy metals has become extremely important in environmental and analytical research because of the strong dependence that toxicity, environmental mobility, persistence and bioavailability of these pollutants have on their specific chemical forms. Novel nano-optical-based detection strategies, c…
In this work, we report the dielectric, impedance, modulus and conductivity study of BaBi4Ti4O15 ceramic synthesized by solid state reaction. X-ray diffraction (XRD) pattern showed orthorhombic structure with space group A21am confirming it to be an m=4 member of the Aurivillius oxide. The frequency dependence dielect…
A flower-like C@MnCo <sub>2</sub> O <sub>4</sub> composite with a hollow structure was synthesized through a hydrothermal method followed by a calcination process, which shows enhanced rate capability and an excellent cycling stability of 95.9% retention after 1000 cycles.
This work was devoted to reinforcement of polyvinyl alcohol (PVA) using cellulose nanofibers from Aloe vera rind. Nanofibers were isolated from Aloe vera rind in the form of an aqueous suspension using chemimechanical technique. Mechanical characterizations showed that incorporation of even small amounts of nanofibers…
Reinforcement of PANI–SA conducting hydrogels is attributed to the interaction of PANI–SA chains and the inter/intramolecular hydrogen bonding within the SA chains.
The production of stable aqueous suspensions of several inorganic graphene analogues was performed by exfoliation of the corresponding bulk layered materials <italic>via</italic> sonication using non-ionic surfactants as dispersing agents.
This article reviews some of the recent biological applications of gold nanoparticles (GNPs) which have been discovered lately by individual studies all around the world. GNPs have emerged as a promising candidates for various biological applications due to their unique physical properties (size and shape dependent),…
A novel electrode material of the three-dimensional (3D) multicomponent oxide NiCo2O4@NiMoO4 core-shell was synthesized via a facile two-step hydrothermal method using a post-annealing procedure. The uniform NiMoO4 nanosheets were grown on the seaurchin-like NiCo2O4 backbone to form a NiCo2O4@NiMoO4 core-shell materia…
A free-standing graphene silk composite (G/S) film was fabricated via vacuum filtration of a mixed suspension of graphene oxide and silk fibres, followed by chemical reduction. Spiky structured Pt nanospheres were grown on the film substrate by cyclic voltammetry electrodeposition. The electrical and mechanical perfor…
A green approach to synthesise nitrogen/sulfur co-doped carbon dots has been developed and the product was successfully analysed by HPLC.
Recyclable, fast and visible-light responsive polymer-dispersed liquid crystal/graphene oxide nanocomposite films were fabricated by solution casting and mechanical stretching.
