Silver nanoplate hierarchical turreted ordered arrays were fabricated through an electro-deposition method on ordered acuate silicon nanocone templates. Such arrays can be used as SERS substrates for trace analyses of streptomycin sulphate, and exhibit high activity and stability. This work is of importance in practical applications based on the SERS effect of noble metal micro/nano-structured ...

the synthesis of nano- structured cobalt through a controlled chemical process followed by heat treating at various temperatures is studied. the product is characterized by icp, xrd, fesem , and tem, indicating that the as- synthesized particles have an amorphous structure with 1.76 for co/b ratio, an average size of 50 nm. the transformation of intermediate phases into single phase nano- cryst...

A facile strategy was developed to delicately control the morphologies of hydroxyapatite materials from simple 0D morphologies to complicated 3D architectures using hard-precursors with similar structures. The present study provides a new platform for hydroxyapatite materials to be efficiently synthesized and manipulated.

Recent developments in grinding have opened up new avenues for finishingof hard and brittle materials with Nano-surface finish, high tolerance and accuracy.Grinding with super abrasive diamond wheels is an excellent way to produce ultraprecision surface finish. However, super abrasive diamond grits need higher bondingstrength while grinding, which metal-bonded grinding wheels ca...

An optical attractor based on a simple and easy to fabricate structured metal-dielectric-metal (SMDM) waveguide is proposed. The structured waveguide has a variable thickness in the vicinity of an embedded microsphere and allow for adiabatic nano-focusing of gap-surface plasmon polaritons (GSPPs). We show that the proposed system acts as an omnidirectional absorber across a broad spectral range...

Nanorods of a three-dimensional Zn(II) metal-organic framework, [Zn₂(btec)(DMF)₂]n (1) (btec=1,2,4,5-benzenetetracarboxylate, DMF=N,N-dimethylformamide), have been synthesized by a sonochemical process and characterized by field emission scanning electron microscopy (FE-SEM), powder XRD and FT-IR spectroscopy. Structural determination of compound 1 was determined by single crystal X-ray diffrac...
