Copper oxide nanoparticles were anchored on sodium dodecyl sulphate (SDS)-functionalized macroporous carbon by utilizing the supramolecular self-assembly of SDS acting as a soft template. The as-prepared composite provides new features of electrocatalytic activities and may hold great promise for the design of environmental sensors.

Flower-like gold nanoparticles (Au-NPs) were fabricated in surfactant-PMo(12) hybrid assemblies, where PMo(12) served as a UV-switchable reducing agent for producing Au-NPs and the organic surfactant matrices played the role of a soft template for the formation of flower-like structure of Au-NPs.

The morphological evolution of PANI helixes was achieved without the use of chiral dopants, but by a facile process through the generation of onion-like multi-lamellar vesicles used as a novel soft-template and a liquid crystal acting as a promoter for PANI polymerization and self-assembly, which is a breakthrough for the synthesis of helical structures.

Personal identification and authentication is very crucial in the current scenario. Biometrics plays an important role in this area. Biometric based authentication has proved superior compared to traditional password based authentication. Anyhow biometrics is permanent feature of a person and cannot be reissued when compromised as passwords. To over come this problem, instead of storing the ori...

Nanocrystalline strontium hexaferrite (SrFe12O19) powders have been successfully synthesized using the facile Co-precipitation method. The ferrite precursors were achieved from mixtures of strontium and ferric chloride in an aqueous medium without any surfactant and soft template. The as-received powders were calcined at 800 and 1000 ˚C for 2 hours in air. The final powders were characterized b...

      Hydroxyapatite (HA) nano-rods with uniform morphology and controllable size have been successfully synthesized in the presence of cationic and non-ionic surfactants by a hydrothermal method. (NH4) 2HPO4 and Ca(NO 3)2.4H2O were used as the phosphorus and calcium sources, respectively. The composition of synthesized powders w...
