Quasi-crystalline geometry for architectrual structures
This document discusses using quasi-crystal geometry for architectural structures. Some key points:
1) Quasi-crystals have an aperiodic structure that breaks from traditional crystal symmetries, allowing new geometric patterns. The document explores using golden cubes and Penrose tilings as the basis for 3D quasi-crystal geometries.
2) For architectural structures, quasi-crystals would need to be stabilized through the addition of connecting bars or plates. The number and placement of stabilizing elements is analyzed to achieve structural stability.
3) Potential architectural applications are explored at multiple scales, from individual building components to urban planning. Quasi-crystals could provide more design flexibility compared to traditional symmetries while still maintaining
CRYSTAL STRUCTURE
The document discusses the concept of a unit cell in crystal structures. It defines a unit cell as the smallest repeating unit that can recreate the entire crystal when translated in three dimensions. There are different types of unit cells depending on the symmetry and structure of the crystal, with the primitive unit cell being the smallest possible. A crystal's unit cell and symmetry determine many of its physical properties.

Solid state chemistry
This document discusses different types of solids and their crystal structures. It describes crystalline solids as having long-range periodic atomic arrangements, while amorphous solids lack long-range order. Polycrystalline solids consist of many small crystallites. Common crystal structures include body-centered cubic, face-centered cubic, and hexagonal close-packed arrangements. Defects in crystal structures like point defects and dislocations are also summarized.
Crystal structure of metals and semiconductors
The document discusses the crystal structures of materials. It begins by explaining that the properties of some materials are directly related to their crystal structures. For example, magnesium and beryllium have different properties than gold and silver due to differences in their crystal structures. It then lists the key learning objectives which include describing different crystal structures, computing densities, and distinguishing between single crystals and polycrystalline materials. The document goes on to explain common metallic crystal structures like body centered cubic and face centered cubic, as well as non-metallic structures like rock salt and cesium chloride. It also discusses factors that determine crystal structure such as the relative sizes of ions to maximize interactions and maintain charge neutrality.

There are several types of defects that can arise in solids, including point defects like vacancies and interstitials, line defects like dislocations, and area defects like grain boundaries. The number and type of defects can be controlled through processing parameters and affect the material properties. While some defects are undesirable, others can play important roles like enabling plastic deformation through dislocation motion. Advanced microscopy techniques allow direct imaging of these defect structures at atomic scales.

X ray diffraction for m.sc. chemistry
X-ray diffraction is a technique used to determine the atomic structure of crystals. When X-rays hit the periodic lattice of atoms in a crystal, the X-rays diffract into specific directions. This was first discovered by Max von Laue in 1912. Bragg's law quantifies the conditions under which constructive interference, and therefore diffraction, occurs for waves scattered by atomic planes in a crystal. X-ray diffraction methods are now commonly used to analyze crystal structures.

We have observed a metallic solid (Al —14-at. /o-Mn) with long-range orientational order, but with icosahedral point group symmetry, which is inconsistent with lattice translations. Its diffraction spots are as sharp as those of crystals but cannot be indexed to any Bravais lattice. The solid is metastable and forms from the melt by a first-order transition.
structures-and-types-of-solids presentation
There are two main types of solids: crystalline and amorphous. Crystalline solids have a highly regular arrangement of particles at the microscopic level, forming crystals. They have a repeating lattice structure made up of points indicating the position of atoms. There are three main types of unit cells that make up crystalline lattice structures: simple cubic, body centered cubic, and face centered cubic. Crystalline solids can be classified based on what type of particle occupies the lattice points, including ionic, molecular, and atomic solids like metals. Metals have a nondirectional covalent bonding structure and exist in crystalline forms with the closest packing of spherical atoms, including hexagonal closest packed and cubic closest packed arrangements.

This document discusses various types of imperfections that can occur in solid materials, including crystalline defects. It begins by noting that real materials have irregularities in their crystal structure compared to the assumed perfect order in previous lectures. Defects are then classified as either point defects (e.g. vacancies, interstitials), line defects (dislocations), or planar defects (e.g. grain boundaries, twins, stacking faults). The document goes on to describe various defect types in more detail and how defects influence material properties. It also discusses grain structure formation during solidification and examines defects using microscopy techniques.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
