Nanoscale fabrication

The nanostructured molecular arrangements from DNA developed by Seeman may find applications as biological encapsulation and drug-delivery systems, as artificial multienzymes, or as scaffolds for the self-assembling nanoscale fabrication of technical elements. Moreover, DNA-protein conjugates may be anticipated as versatile building blocks in the fabrication of multifunctional supramolecular devices and also as highly functional-...

Most of the reported nanostmctured actinide compounds considered here have been obtained under soft S5mthesis conditions (room-temperature crystallization from aqueous solutions). Most of these compounds are soluble and it is rather hard to foresee any practical application of them. However, findings reported here demonstrate the possibility of nanoscale fabrication for actinides in higher oxidation states. For instance, we expect that a whole new range of uranium-based nanotubular and nanocomposite materials can be... 

In the past, most studies have examined surfaces with topographical features on the microscale level, due to limitations in nanoscale fabrication. However, recent advances in creating surfaces with submicrometer surface features have allowed analysis of more biologically relevant features. Nanometer-size topographical features more closely mimic the natural ECM, thus enabling researchers to more accurately recreate a cell s in vivo environment. 

EMM with ultrashort voltage pulse and much smaller lEG improves the precision to nanometer range and provides an alternative to the established nanoscale fabrication technologies which are mostly limited to two-dimensional structures. EMM can also be successfully utilized for nano-fabrication of three-dimensional structures with much lesser cost and lesser time which is still a challenge to the researchers. However, this area of EMM requires in-depth research to make it commercially successful in various nanotechnology applications. 

Basic modules with the design shown in Figure 3.24 are frequently used in sensor technology. By the way, such a device has been used for the detection of the curing behavior of coatings [169]. The trend goes to nanoscale fabrication in... 

The methods for miniaturization of chemical and biosensors are based on an extension of VLSI fabrication techniques, however with a broader range of materials [1-6], The range of materials is beyond what is normal for IC electronic devices because additional functionality is needed. These materials include electrochemi-cally active metals with catalytic properties, conductive oxides, and high-temperature materials. Examples of metal oxides include Sn02, WO3, and Ti02, and other catalytic metals include Pt, Ru, Ir, Pd, and Ag needed for electrochemical sensors [7,8]. As the dimensions of semiconductor devices continue to move to smaller gate lengths, nanoscale fabrication techniques are now developed. Hence, stmctures for sensors... 

In this entry we describe the basic processes and lithography which is the foundation of miniaturization, followed by a description of a range of methods for depositing thin films. Throughout the entiy examples will be provided to illustrate the versatility of the micro-/nanoscale fabrication processes for the manufacture of chemical sensors. 

Relatively recent advancements have been made in the understanding of heterogeneous ORR catalysis using the combination of molecular and atomic level simulation tools, nanoscale fabrication methods, and nanoscale characterization techniques. For example, the early experimental work of Markovic [17], combined with the important theoretical work of Nprskov [18], Mavrakakis [19], Neurock [20], and others, has now given a deeper understanding not only of the thermodynamics involved in the ORR, and the likely cause of the associated overpotential. 

The third approach is modifying the surface morphology. For example, super-hydrophobicity (contact angle approaching 180 degrees) may be accomplished when a surface is covered wi nanoscale fabricated structures [18].
