Technical challenges

Known specific toxicides of nano- and nano/bio-based materials 

Known receptor and ligand interactions for a number of probable targets 

Nano-based therapeutics Ability to design nano-materials for ease of administration 

A family of animal models that support the evaluation of nanomaterials. In order to obtain FDA approval, the animal models must be relevant to the human model. The animal models need to identify and verify nanomaterial fate, toxicity, pharmacokinetics, and immune response. 

To better advance technologies that meet practical, in-field deployment requirements, a mechanism is needed to monitor progress of technology development compared to snch that it continues in line with reality and with milestones. Moreover, there shonld be a mechanism by which companies are encouraged to participate in the research in the early stages to help maintain the focus on the end-point and the needs of the end user.

Laborelec is the laboratory of the Belgian electricity industry. The laboratory is in charge of solving and anticipating the technical challenges related to the power generation, transmission and distribution of electricity. 

The advantages of homogenous immunoassays are simple formats and rapid data output producing user-friendly and cost-effective products. Technical challenges to consider, however, are the necessity to remove or minimize background interference from the reagents and nonspecific binding reactions. 

Flashspun high density polyethylene fabrics have been commercial since the 1960s however, this is a proprietary and radically different process of manufacturing a spunbonded fabric, more technically challenging to produce, and highly capital intensive. 

Polymeric surfaces are fundamentally different from metal oxide surfaces, and consequently the technical challenges to obtaining strong and durable adhesive... 

Whatever the battciy construction and mix of materials being considered, the technical challenges facing developers are... 

USA. In Europe the technical challenge of recharging but also saving money, continues to be stronger than elsewhere [4]. 

This chapter looks at the particular question of polymers and the environment. A book on the science of polymers ought to give some consideration to this issue because of the growing concern about the effect of discarded plastic on the quality of life on Earth. If we are to produce and use polymers in ways that are more environmentally responsible (and society will increasingly demand that we do) then there will be new technical challenges to face. One purpose of this chapter is to indicate what some of these challenges might be. 

The rapid pace of development of our world over the last century has heen largely based on easy access to fossil fuels. These resources are, however, limited, while their demand is growing rapidly. It is also becoming clear that the scale of carbon dioxide (CO2) emissions following the use of fossil fuels is threatening the climate of the Earth. This makes the development of sustainable production and energy solutions in industry, transportation, and households the most important scientific and technical challenge of our time. 

Ihe implementation of the Resource Conservation and Recovery Act (RCRA) and the Comprehensive Environmental Response, Compensation, and Liability Act (Superfund) has underscored a number of the weaknesses in our capabilities to measure the chemical characteristics of wastes. We are now being called upon to identify and quantify with unprecedented sensitivity hundreds of chemicals found in many types of materials within waste sites, near discharges of hazardous contaminants, and in the surrounding environments. Extrapolations from a limited number of measurements must indicate the general environmental conditions near waste sites. The measurements have to be made faster and cheaper than ever before, with the precision and bias of each measurement fully documented. Thus, the technical challenges facing the monitoring community are substantial. 

Of course, water molecules are not NMR silent and NMRI engineering has, indeed, advanced at a remarkable pace to provide extraordinary technical capabilities. These capabilities now enable studies of systems beyond those in the biomedical arena, systems that are, in many respects, far more technically challenging. This has led to the development of innovative and fascinating strategies and tactics to deal with NMRI-unfriendly samples and conditions. 

Studies of thermally denatured proteins remain technically challenging owing to the propensity of thermally unfolded proteins to aggregate. Despite this potential difficulty, small-angle scattering techniques have been employed in the characterization of a number of thermally unfolded states. 

A modern variation on the rapid scan spectrometer, which is under development, uses a laser-generated plasma as a high intensity broad-band IR source (65). This method has been used to probe the vc—o absorption of W(CO)6. Another technique TRISP (time-resolved IR spectral photography), which involves up-conversion of IR radiation to the visible, has also been used to probe transients (66). This method has the enormous advantage that efficient phototubes and photodiodes can be used as detectors. However, it is a technically challenging procedure with limitations on the frequency range which depend on the optical material used as an up-converter.
