Mixed metal nanoparticle assembly and the effect on surface enhanced raman scattering [PDF]
Here we report the assembly of mixed metal nanoparticles using an oligonucleotide-templated approach. Substitution of one of the gold nanoparticle probes with an analagous silver probe to produce a hetero-metal duplex permitted surface enhanced Raman ...

Controlled side-by-side assembly of gold nanorods and dye molecules into polymer-wrapped SERRS-active clusters [PDF]
The controlled side-by-side assembly of gold nanorods in solution together with Raman reporter dye molecules to create small SERRS-active clusters stabilised by a surrounding polymer layer is demonstrated.

Room-Temperature Multiferroic Liquids: Ferroelectric and Ferromagnetic Order in a Hybrid Nanoparticle-Liquid Crystal System. [PDF]
A hybrid fluid combining ferrimagnetic nanoplatelets and a ferroelectric nematic displays coexisting magnetization and polarisation at room temperature. This self‐assembled multiferroic shows strong magnetoelectric effect and nonlinear optical response, offering a soft, reconfigurable platform for next‐generation sensing, actuation, and photonic ...

Microbial-Physical Synthesis of Fe and Fe3O4 Magnetic Nanoparticles Using Aspergillus niger YESM1 and Supercritical Condition of Ethanol [PDF]
Magnetic Fe and Fe3O4 (magnetite) nanoparticles are successfully synthesized using Aspergillus niger YESM 1 and supercritical condition of liquids. Aspergillus niger is used for decomposition of FeSO4 and FeCl3 to FeS and Fe2O3, respectively.

A Second Harmonic Wave Angle Sensor with a Collimated Beam of Femtosecond Laser
An optical angle sensor based on the collimated mode-locked femtosecond laser (Fs) beam, in which the angle measurement is carried out by observing the second harmonic wave generated by irradiating the Fs beam towards MgO:LiNbO3 crystal, is proposed. The

Lasers for Nanometrology [PDF]
AbstractOver the last few decades the interest in phenomena on nanoscale or even atomic scale has increased significantly.A prominent, but at the same time very demanding technique is atomic force microscopy (AFM). AFM can reveal surface topographies at atomic resolution or be used to measure small forces in the range of only a few piconewtons.
