keynote: Advantages and Limitations of Nanotechnology
Biography:


Abstract:
Nanotechnology is the science to manipulate the matter in nanoscale. It is seen as the way of the future and this technology is believed to bring benefit in our daily life. But, no technology can be perfect and there will always be advantages and limitations of all the existing and future technologies.

Advantages of Nanotechnology:
  • Nanotechnology can actually revolutionize a lot of electronic products, procedures, and applications. The areas that benefit from the continued development of nanotechnology when it comes to electronic products include nano transistors, nano diodes, plasma displays, quantum computers, and many more.

  • Nanotechnology can also benefit the energy sector. The development of more effective energy-producing, energy-absorbing, and energy storage products in smaller and more efficient devices is possible with this technology. Such items like batteries, fuel cells, and solar cells can be built smaller but can be made to be more effective with this technology.

  • Another industry that can benefit from nanotechnology is the manufacturing sector that will need materials like nanotubes, aerogels, nano particles, and other similar items to produce their products with. These materials are often stronger, more durable, and lighter than those that are not produced with the help of nanotechnology.

  • In the medical world, nanotechnology is also seen as a boon since these can help with creating what is called smart drugs. Compared to traditional drugs, this approach could help cure people faster and without the side effects. We also find that the research of nanotechnology in medicine is now focusing on areas like tissue regeneration, bone repair, immunity and even cures for such ailments like cancer, diabetes, and other life threatening diseases.

  • Compared to synthetic chemistry approach, nanotechnology provides an easy access for developing multifunctional agents for tumor-imaging and therapy- a "See and Treat" approach.

Limitations of Nanotechnology:
  • The development of nanotechnology can also bring adverse impact on certain markets, e. g., lowering of the value of oil and diamonds due to the possibility of developing alternative sources of energy that are more efficient and won't require the use of fossil fuels. This can also mean that since people can now develop products at the molecular level, diamonds will also lose its value since it can now be mass produced.

  • Atomic weapons can now be more accessible and made to be more powerful and more destructive. These can also become more accessible with nanotechnology.

  • Since these particles are very small, problems can actually arise from the inhalation of these minute particles, much like the problems a person gets from inhaling minute asbestos particles.

  • In drug formulation, reproducibility/stability from batch to batch, especially in large scale manufacturing could be problematic.

  • Desirable pharmacokinetic/pharmacodynamics profiles (in humans) of certain nanoparticles may be difficult to achieve on the basis of animal results. Therefore, it is the responsibility of the scientific community to have a serious look on a particular technology before recommending it for its use, especially in healthcare.

Abstract:
Organic and printed photovoltaics (OPVs) onto plastic substrates have attracted an enormous interest in the modern science & industry, due to their several advantages that include conformability to curved surfaces and potentiality for fabrication by low-cost production processes such as roll-to-roll (r2r) printing. One of the main factors that determines the achievement of high OPV efficiency is the optimization of the morphology of the photoactive layer, which is a blend of a polymer electron donor and a fullerene-based electron acceptor. Also, the optimization of the quality of the OPV printed nanomaterials (organic semiconductors, transparent electrodes, barrier nano-layers etc.) onto flexible polymer substrates is a prerequisite for the achievement of the required performance, efficiency and lifetime of OPVs that will enable their wide market exploitation.

In this presentation, we provide an overview of the latest advances on the fabrication of advanced nanomaterials for OPV applications by r2r printing methods, in combination with laser scribing (in both sheet-to-sheet and roll-to-roll configurations) of the different OPV layers (transparent electrodes, photoactive layers, metal electrodes). The methodology for the combination of the different printing and structuring techniques will enable the low-cost fabrication of OE devices for several consumer applications. Also, we present the novel methodology for the combination of in-line Spectroscopic Ellipsometry (SE) working in the near infrared to visible and far ultraviolet spectral region and Raman Spectroscopy (RS) for the robust investigation of the optical properties, morphology and bonding structure of r2r printed OPVs. Finally, we demonstrate the potentiality of SE and RS to be used as standard tools for the in-line robust determination of the thickness, optical and structural properties and the quality of other thin films and nanolayers for many organic and printed electronics applications.

Istvan Halasz
PQ Corporation, USA
keynote: Combination of experiments and computer modeling for exploring fine structural details in amorphous silica and zeolites
Biography:
Si and O are among the most abundant elements in the universe and SiO2, also named as silica, is the most copious mineral in the Earth's crust. Thus, silica derivatives have been utilized from prehistoric times. Beyond ceramic, glass and construction applications, today's diverse utilizations include the manufacturing of cosmetics, paper, beer, rubber, polymers, gasoline to name but a few examples. Nano and sub-nano sized particles and pores play pivotal role in many silica applications, for which our company supplies material. Our task at the R&D center is to help to adjust material properties to the different needs. In this presentation I will show in a few examples how we combined various experimental techniques, from porosity tests through atomically resolved electron microscopy to solid state NMR and molecular spectroscopy, with force field and DFT (density functional theory) based model calculations to elucidate curious or only empirically explored material properties at the molecular level.

Abstract:
Istvan Halasz obtained Magna Cum Laude doctorate degree from the Lajos Kossuth University and the Academy of Sciences (HAS) in Hungary. In the Hungarian Hydrocarbon Institute he developed and scaled up efficient processes for pharmaceutical, fine chemical and petrochemical industries beside fundamental acid-base catalytic studies. Later in the Chemistry Institute of HAS and at USA universities he studied zeolite catalysis, high temperature superconductor synthesis, and catalytic fume abatement for automobile exhausts and stack gases. For the past 17 years he has investigated the properties of silicates at PQ R&D. Chaired the Philadelphia Catalysis Club; current president of North-East Corridor Zeolite association (NECZA); edited a book about recent catalytic applications of silica, authored 120+ book chapters, journal papers, and patents and held 80+ conference presentations.
