This chapter presents the outstandingly large glass-forming ability of the new Pd 40 Cu 30 Ni 10 P 20 alloy through the investigation of in situ undercooling behaviour using a thermal analysis technique. In order to demonstrate the large glass-forming ability of the new palladium-based quaternary metallic glass, the p…
In previous chapters, we have introduced a number of S-FEM models and demonstrated the excellent properties and performance of these models for general problems of solid mechanics defined (by default) in a Lipschitzian domain (i.e., not singular). This chapter aims to extend the application of these S-FEM models for a…
Volatile organic compounds (VOCs) generally are fuels that are easily combustible. Through combustion, which is synomonous with thermal oxidation and incinceration, the organic compounds are oxidized to CO and water, while trace elements such as sulfur and chlorine are oxidized to species such as SO and HCl. Three com…
Dielectric and electro-optic low-frequency analyses are the basic source of information on the electric polarization of charged colloids. In electro-optic investigations, the saturation curves are used to apply fitting procedures to test theoretical constructions or to obtain the saturation value at complete particle…
Quality control procedures are necessary to ensure that the obtained analytical data and reported values are correct. Validation and approval of analytical data are based on a well-designed and regularly applied quality assurance/quality control (QA/QC) program. The components of this program are divided into a manage…
Matter is anything that has mass and occupies space. Matter is found in many different forms, and every year thousands of new types of matter are synthesized. Matter is grouped into two major classes: pure substances and mixtures. Pure substances are subdivided into elements and compounds. Elements are pure substances…
Pseudopeptidic compounds are chemical entities that combine peptide-like moieties with nonnatural substructures. Therefore, they are ideal scaffolds for setting up non-covalent interactions of different nature. These interactions can be used for improving the synthesis of challenging architectures like macrocycles and…
Weiss and Forrer (1926) showed experimentally that TðI2Þ dependences in ferromagnets are linear in the paraprocess region in accordance with equations (2.42) and (2.50). Extrapolating the linear part of TðI2Þ to the I2 axis, Weiss and Forer (1926) determined a value of spontaneous magnetization I2s at various temperat…
This chapter focuses on the nucleation mechanisms of highly potent heterogeneous sites in aluminium castings, separating the potential influences of nucleation and growth restriction. Heterogeneous nucleation in aluminium alloys is still the weak link in the understanding and modelling of grain refinement as a nucleat…
Samples containing particulate or organic material generally require pretreatment before analysis. Colorless, transparent samples (primarily drinking water) containing a turbidity of less than 1 NTU (nephelometric turbidity unit), and single-phase samples can be analyzed directly via atomic absorption spectroscopy or…
Pencemaran logam berat Kadmium (Cd) di perairan dapat mengganggu kestabilan ekosistem di perairan karena logam sukar untuk didegradasi. Pencemaran logam berat secara tidak langsung dapat terakumulasi melalui rantai makanan. Chlorella sp. adalah mikroalga yang dapat digunakan sebagai agensia bioremediasi yang baik dan…
The possibility of implementing microwave technology to photoresist film curing which is a major process in the production of electronic printed circuit boards (PCB) was investigated and compared with a conventional curing method, e.g. UV lithography. Since both techniques involved irradiation, hot plate curing which…
This chapter discusses the electro-optical properties of the compounds only with covalent type of C 60 linkage. It reviews properties of fullerenes themselves detected by optical Kerr effect and electro-optical Kerr effect in solutions. The chapter describes electro-optical behavior of C 60 adducts, and presents analy…

The unique properties of bacterial nanocellulose (BNC) provide the basis for a wide range of applications in human and veterinary medicine, odontology, pharmaceuticals, acoustic and filter membranes, biotechnological devices, and in the food and paper industry. In this chapter, an overview of surface modifications of…
This PhD focuses on the relationship between the preparation process and the structure of polypropylene/clay nanocomposites. First, the samples were prepared via an internal mixer. Scanning electron microscopy observations, completed by X-ray diffraction analysis and rheology measurements enabled us to characterize th…
Abstract For the safety of spent nuclear fuel assemblies stored in storage pool in the extreme condition where the water is lost completely, a passive spray cooling technique was designed, and its effectiveness has been validated by a functional experiment. The spray cooling characteristics of the spent fuel assembly…
