What is a Nanostructure? 
It is exciting to see new nano-structures being discovered and developed on a persistent basis. There is no nomenclature code for any of these structures making it easy to mistake one for another. A chart is presented here to simplify the characterization process.

At any rate, a structure on the nanoscale has been accepted to mean a physical entity that is 100nm or smaller. This structure may be a single component of a single material (e.g. Au nanoparticle). The structure may also be more sophisticated, including TiO2 nanofibres and three dimensional architectures.

The methods of manufacturing nanostructures range from natural processes such as volcano eruptions to synthetic processes such as laser irradiation. The choice of technique depends on the desired synthesis controllability, versatility, mass quantity and cost.

What nanostructures can do for us is both harm and good. Ultra-fast and large surface area reactions mean more efficient energy, faster patient rehabilitation, improved sustainability etc. but we need to keep mindful of the long-term effects. Industrial and governmental cooperation is critical in this aspect as we explore new potentials.

Raman Spectroscopy 
Incident energy may shift due to characteristic vibration modes of a molecule or compound. In the case of Raman Spectroscopy, typically visible light may be Stokes-shifted by a particular wavenumber. The resulting spectrum is often regarded as a fingerprint identification of a molecule. The quality of this spectrum is dependent on factors such as sample stability, sample fluorescence and scattering intensity. The later factor is subject to expensive studies involving surface-enhanced Raman spectroscopy (SERS). SERS has been successfully deployed in situations requiring label-free, non-invasive and on-site analysis. Established applications include, but are not limited to: nanostructure characterization, biomolecular detection, environmental pollutant detection etc. Check out our latest Raman solutions (link).

 

 

Solar Energy 
An ongoing aspiration of the solar energy industry is towards an efficient, sustainable, cheap manufacturing and operations of harvesting the energy of our Sun. Concentrated solar collectors, photosynthetics and photovoltaics are just some project areas. Both Si and  TiO2 are materials of choice that are experiencing tremendous developments in terms of the material purities, bang-gap activations and absorption efficiencies.

At Open NDTM, we put our theoretical and practical skills to the test. Our manufacturing pipeline includes experience in TiO2 solar cell design as well controlling Si absorption efficiency. We eagerly look forward to our next challenge.
Bio-scaffold 
Tissue regeneration is more than a cosmetic initiative, it is targeted to enhance or replace natural biological functions. The aim is to help various cells (e.g. bone, blood vessel, skin etc.) to regenerate faster and happier. Scaffold systems play a major role in tissue engineering as cell behavior is directly correlated to surface interactions.

At Open NDTM, we have a proven capability of improved bioactivity by mimicking an extracellular matrix based on a porous TiO2 3D nanofibrous architecture. Ask us about our biomaterial expertise.
