This chapter contains sections titled: Introduction to Colloidal Silica Chemistry of Silica Surface Functionalization by Organosilanes Characterization and Product Properties of Silane–Modified Silica Dispersions Applications for Silanized Silica Nanoparticles in Paint and Coatings Conclusion and Outlook
The presence of oxo and carboxylate ligands is crucial to decreasing the redox potentials of the oxygen evolving complex (OEC). It has been proved that negatively charged ligands can stabilize the high oxidation states of various transition metal-based complexes and lower their oxidation potentials. This chapter focus…

Nanotechnology along with its nanoengineering materials has become a new area of research that may soon revolutionize the traditional medicine management. Nanotechnology offers promising tools for the targeted delivery of various drugs, molecules, DNA, and so on to specific tumor sites, highly sensitive diagnosis, ima…
Des produits de consommation de première nécessité aux produits les plus fortuits, l'emballage, en particulier plastique, constitue aujourd'hui un élément indispensable de notre vie quotidienne. Son utilisation intensive dans le domaine agroalimentaire pour un usage unique à courte durée de vie incite aujourd'hui à s'…
Thermally responsive shape memory alloys (SMA) demonstrate interesting properties\nlike shape memory effect (SME) and superelasticity (SE). SMA components in\nthe form of wires, springs and beams typically exhibit complex, nonlinear hysteretic\nresponses and are subjected to tension, torsion or bending loading conditi…
Dispersant materials used in response to oil spills undergo a demanding effectiveness approval process, and approved dispersants are stockpiled near drilling activity and possible spill locations. The molecular versatility of poly ethylene oxide (PEO)/PEG polymers in solution makes them a challenge for molecularly spe…
This chapter contains sections titled: Introduction Solid Particles Nanocapsules Ultra–Thin Silicone Films Conclusion and Outlook
Since the advent of “Nanomedicine,” which refers to the applications of nanotechnology for the treatment, diagnosis, monitoring, and control of the biological machinery, there has been a significant change in the paradigm of cancer diagnosis, treatment, and prevention. Nanomedicine provides great promise for the treat…
This chapter contains sections titled: Introduction Lubrication of Pharmaceutical Containers and Devices Silicone Oil: A Molecular Perspective Silicone Oil Coatings in Pharmaceutical Devices Protein Adsorption to Hydrophobic Interfaces Physical Stability of Biologics in the Presence of Silicone Oil Overcoming Silicone…
Due to the possibility of the adverse effects of nanomaterials, many regulatory agencies, such as governmental bodies and international organizations, have initiated regulatory activities to protect consumers from any potential harm. Since nanomaterials have been used in many different areas, various regulatory plans…
There is an increasing requirement to identify the hazard of silver nanoparticles (AgNPs) and develop a test strategy to evaluate genotoxicity of AgNPs because of the rapid growth in the application of AgNPs-containing consumer products. There are a number of studies on genotoxicity of AgNPs using different genotoxici…
This chapter contains sections titled: Introduction Inorganic Materials as Candidate for Nanocomposite Formation Nanocomposites as Non-Halogenated Flame Retardation Solutions Combinations of Nanocomposite with Traditional Flame Retardants Contribution of Nanocomposites to Achieve New FR Cable Standard (EU CPR) New Dev…
We describe a computer algorithm that searches for substitution rules on a set of triangles, the angles of which are all integer multiples of π/n. We find new substitution rules admitting 7-fold rotational symmetry at many different inflation factors.
RF sputtered ZnO and Al:ZnO films are attractive transparent conductive oxides for fabrication of opto-electronic devices. In this paper we present efforts to control carrier concentration and mobility of ZnO/Al:ZnO thin films by controlling deposition parameters (RF power, pressure and substrate temperature. Al:ZnO t…
Biological barriers represent a stumbling block to the pharmacological treatment of lesions occurring in central nervous system or retina. The advent of nanodrugs was welcomed as a means to tide over and cross the barriers. Expectations, however, have not been completely fulfilled, as nanocarriers often accumulated at…
The possible reaction path for O–O bond formation has been a point of contention among investigators of water oxidation, but there is a growing consensus acknowledging two main pathways: (1) a nucleophilic attack of water on a high-valent metal–oxo species, and (2) a coupling reaction of two metal–oxo species to give…
