A glass of Er doped Li2O-Nb2O5-SiO2-B2O3 with an addition of CuO or Sm2O3 crystallizing nonlinear optical lithium niobate LiNbO3 (LN) is developed. Crystalline lines of LN have been fabricated on the glass surface by continuous wave Yb fiber laser irradiations with a wavelength of 1080 nm. The laser written LN crystalline lines have been found, by means of electron back scattering method, micro...

Synthesis and characterization of nano-crystalline silicon grown by atom beam sputtering technique are reported. Rapid thermal annealing of the deposited films is carried out in Ar + 5% H2 atmosphere for 5 min at different temperatures for precipitation of silicon nano-crystals. The samples are characterized for their optical and structural properties using various techniques. Structural studie...

In order to machine micro structured dies and molds made of ceramics, micro milling tools made of poly-crystalline diamond (PCD) are developed. Many cutting edges are ground with diamond wheels. Tool wears of the PCD milling tool are evaluated by cutting spherical molds made of binder-less tungsten carbide and structured surfaces are machined for trial. From the experiments, it is clarified tha...

Tubular structures built from amphiphilic molecules are of interest for nano-sensing, drug delivery, and structuring of oils. In this study, we characterized the tubules built in aqueous suspensions of a cholesteryl nucleoside conjugate, cholesterylaminouridine (CholAU) and phosphatidylcholines (PCs). In mixtures with unsaturated PCs having chain lengths comparable to the length of CholAU, two ...

A organic-solution-processable functionalized-graphene (SPFGraphene) material has been studied on pre-concentration and determination of trace Mo(II)ions. In this process, the effects of pH solution, elution conditions on pre-concentration of trace Mo(II) were studied and the effect of interfering ions was also investigated. A selective method for the fast determination of trace amounts of Mo (...

A  facile  effective  stirring  aging  at  room  temperature  prior  to  conventional  hydrothermal treatment was employed in the template-free synthesis of micro- and nano-crystalline sodalites with  two  different  initial  gel  compositions.  The  effect  of  initial  Si/Al  molar  ratio,  NaOH concentration and stirring aging time were investigated on the morphology and particle size of the...

Photovoltaic devices directly convert solar energy into electricity, and thus are highly attractive for a wide range of applications. Although the energy harvested by solar cell technology accounts for only about 0.04% of today’s global energy consumption1, it is one of the fastestgrowing energy sectors, in part because of the vast research and development efforts that have been undertaken in r...

The Special Issue on “Crystalline Micro- and Nano-Materials for Medical Other Biochemical Applications” is a collection of seven original articles (including three research papers four review papers) dedicated to theoretical experimental work that provides new insights practical findings in the field crystal-related biomedicine [...]
