The exploitation of by-products of fruit and vegetable processing as a source of functional compounds and their application in food is a promising field which requires more interdisciplinary research in the following aspects  

The ready availability of starch-based industrial wastes and their renewable nature merit their use as substrates for poly-betahydroxybutyrate (PHB) production from activated sludge. This would not only utilize the excess sludge generated and reduce the load on landfills, but would also contribute to reduction in the cost of PHB production by avoiding sterile conditions and pure carbon sources for maintenance and growth of pure cultures. PHB content is the most important factor affecting the production cost of PHB due to its effect on PHB yield and recovery efficiency, followed by cultural conditions and carbon substrates used (Khardenavis, 2007).

Clearly, neutron reflectivity has contributed much to our understanding of the nature of surfactant adsorption at the solid-solution interface. It has already been successfully applied to an extensive range of systems, as illustrated in this chapter. 

The ability to manipulate the neutron refractive index, through D/H isotopic substitution, makes it a powerful technique for the study of mixtures, and for more detailed structural investigations. This is an aspect of the technique that will clearly be important in the future as more complex multi-component systems are investigated. 

Although in the direction normal to the surface, relatively high-resolution structural information is already accessible in the plane, there is relatively little direct information on a relevant length scale available. Current developments in the technique associated with off-specular scattering will address this over the next 2-3 years, and this will transform our ability to obtain the relevant structural information in the plane of the surface. Hence, the degree of surface ordering and the extent of the bilayer or micellar patches will be accessible. 

The associated and paralleled developments in GISANS will provide access to not only the surface, but also to the near surface structure, and this will enhance considerably our ability to study ordered and relatively more concentrated systems.

An example of potential-modulated FT-IR measurements is shown in Fig. 8.32. The figure shows a Cole-Cole plot of the in-phase [Re(AA)] and quadrature [Im(AA)j components of the band intensity at 1618 cm from a 4-PySH SAM on an Au electrode. The data at several potential-modulation frequencies form a semicircle as in a.c. impedance, from which kinetic parameters can be extracted [137]. Kinetic parameters can also be obtained from the in-phase and quadrature components of the modulated IR signal measured at a fixed modulation frequency [138]. 

As has been discussed in the preceding section, most of the recent ATR-SEIRAS measurements are carried out simultaneously with electrochemical 

In addition to the expansion of time resolution, the expansion of spectral range to far IR is also desirable, since metal-adsorbate vibrations and surface vibrational modes occur in this range. The available spectral range is now limited by the prism ( 900 cm for Si and 700 cm for Ge), the low intensity of the light source, and the low sensitivity of detectors. Since the absorption coefficient of Si fortunately decreases in the far-IR region, ATR-SEIRAS in the far-IR wiU be possible with the use of a synchrotron far-IR facility and a helium-cooled bolometer [142].

On the basis of these discussions, the molecular-scale model for the lipid-cholesterol complex is proposed, as shown in Fig. 18.10b. Before that time, several models for the lipid-cholesterol complexes were proposed on the basis of the results obtained by spectroscopic methods and molecular dynamics simulations. However, it had been difficult to unambiguously determin the molecular-scale structure. The result obtained in this experiment showed that FM-AFM can be a powerful means to determine the molecular-scale structure of biomolecular complexes. 

In addition to the structure of the molecular surfaces, the distribution of water and ions interacting with the surface is also visualized by FM-AFM. Finally, the molecular-scale arrangement of the unknown biomolecular complex (i.e., the lipid-cholesterol complex) was determined by FM-AFM imaging. 

Until recently, the use of FM-AFM in liquid was very limited. However, several AFM research groups have already started to use it for their own applications. Kawakatsu et al developed a low-noise cantilever deflection sensor using a Doppler interferometer and obtained atomic-resolution images of mica in liquid. Umeda et al. reduced the deflection noise by modifying the cantilever 

Because of the existence of the hydration layers, a solid-liquid interface has a vertical extent up to a few nanometers, which is much broader than that of a solid-vacuum interface. It is possible to investigate vertical and lateral distribution of water by taking a one-dimensional (ID) force profile and a 2D height image, as shown in Fig. 18.8. 

However, understanding the three-dimensional (3D) interfacial phenomena by taking ID profiles and 2D images is often too inefficient or too inaccurate to be used in a practical study. The author and coworkers recently developed a method referred to as 3D scanning force microscopy (3D-SFM), where the tip is scanned in the vertical direction as well as in the lateral direction. The method made it possible to image the 3D distribution of water molecules at the mica-water interface with atomic-scale resolution in 53 seconds, as shown in Fig 18.11. 

Concerning the reaction types that would be studied in the futiue, it is of interest in carbocatalysis to show that this concept can be used to promote reaction types that are cmrently considered to be catalyzed exclusively by metals. A target in the area of carbocatalysis should be to show that G type materials are active for cross-coupling reactions, oxidations, hydrogenations, and any other types in which metals are now being applied. 

With regard to the use of G materials as supports, also design and modification of G support to increase the interaction with the metal are key concepts to fully exploit the promises hold by the 2D morphology of Gs and their interaction with the metal NPs. The target in this area is to show the advantages in terms of optimal use of support, fine tuning of the catalytic activity of the metal and stability of G-based supported catalyst with respect to any other support including metal oxides. 

Considering the featmes of G as one atom thick surface combining the possibility to imprint the active site or support the metal NPs, the use of G could lead in a few years to a drastic change in the panorama of catalysis optimizing the use of noble and critical metals and reducing the dependency of catalysis on these inorganic elements.
