Chemistry is the study of matter, its properties, and its reactions. It examines how substances combine or change through various reactions and interactions. Chemistry can be considered a physical science as it studies matter and its transformations but does not examine living things. Some major branches of chemistry include organic chemistry, inorganic chemistry, analytical chemistry, physical chemistry, and biochemistry. Chemistry plays an important role in daily life through applications in food, medicine, cleaning products, and more.
Matter is everything that has mass and takes up space. It is made up of tiny particles called atoms, which can combine to form molecules or compounds. There are three main states of matter: solid, liquid, and gas. Matter undergoes physical or chemical changes that alter its properties but not its chemical makeup.
This document defines the three states of matter - solids, liquids, and gases. It explains that solids have particles that barely move and hold a defined shape, liquids have particles that flow freely but maintain a constant volume, and gases have particles that have no defined volume or shape and move very quickly. The document also notes that all states of matter are made up of particles that move at different speeds depending on whether they are a solid, liquid, or gas.
Waves can transfer energy from one place to another. There are two main types of waves: longitudinal waves, which vibrate the medium in the direction of travel, and transverse waves, which vibrate at right angles to the direction of travel. The key parts of a wave include the crest (high point), through (low point), wavelength (distance between corresponding points), and amplitude (maximum vibration distance from rest position).
Motion refers to the change in an object's position or location over time. Kinematics is the study of motion without regard to forces or energies. An object is considered in motion if its position changes relative to a reference point.
Velocity refers to both an object's speed and direction of motion. Speed in a given direction is called velocity. Average speed is calculated by dividing the total distance traveled by the total time taken. Instantaneous speed refers to an object's speed at a given instant in time.
Acceleration is a vector quantity that represents the rate of change of velocity. It occurs when an object changes its speed. The formula for calculating acceleration is the change in final velocity minus initial velocity divided by the change in time
Energy is the ability to do work or cause change and there are different types, the most important being kinetic and potential energy. Kinetic energy is related to motion and calculated using the formula of half mass times velocity squared, while potential energy is energy that can be released to transform into kinetic energy, as stated by Newton's law of conservation of energy. This law says that energy is neither created nor destroyed, merely changed from one form to another, which is important for understanding how devices like solar panels and batteries work by transforming energy. Other types include chemical (stored in food), thermal (related to heat), and nuclear (from atomic nuclei fusion or fission).
Atoms form ions by gaining or losing electrons to achieve a full outer electron shell like noble gases. Ions then bond to form ionic compounds between metals and nonmetals like NaCl. Covalent bonds form when atoms share electrons to achieve full outer shells, like in H2O. Polyatomic ions, which are ions of two or more bonded atoms, can also participate in ionic bonding, such as Ca(OH)2 which contains hydroxide ions bonding to calcium ions. The number of each type of atom in a compound is shown by subscripts based on the ions formed.
This document provides information on chemistry topics including the structure of matter, states of matter, classifying substances, physical and chemical properties, and changes in matter. It defines key terms like elements, atoms, the periodic table, and reactivity. Chemistry is the study of matter and its changes through chemical and physical transformations.
Chemistry is the science that studies the composition, structure, and properties of matter. It plays an important role in our daily lives through the materials we use and consume like fuels for cars, medicines, and food. Ancient civilizations had a basic understanding of chemistry through extracting metals, making alloys and ceramics, and using fermentation. The field of chemistry began to take shape in the 17th century with Robert Boyle's work developing the scientific method and questioning existing theories through experimentation.
Elements are composed of atoms of the same class that can be found naturally or created artificially in a laboratory. There are four main types of elements: alkali metals, halogens, transition metals, and noble gases. Noble gases are the most stable elements with full outer electron shells, while halogens have seven outer electrons and alkali metals have one. Transition metals occupy the central portion of the periodic table. Elements are classified based on their atomic numbers and valence electrons.
Redox reactions involve the transfer of electrons between atoms or molecules. During redox, oxidation and reduction occur simultaneously. Oxidation is the loss of electrons by an atom, increasing its oxidation state, while reduction is the gain of electrons by an atom, decreasing its oxidation state. Metals typically undergo oxidation by losing electrons, while nonmetals gain electrons through reduction. The oxidation states of elements in compounds can be determined based on established rules and used to balance redox reactions.
This document defines and explains key chemistry concepts such as chemical bonds, molecules, substances, pure and not pure substances, compounds, covalent and ionic bonds, polyatomic ions, protons, electrons, valence electrons, and the periodic table. It discusses how chemical bonds form between atoms through the sharing or transfer of electrons. It also describes the differences between pure substances like elements and compounds, and not pure or heterogeneous substances. Key aspects of the periodic table such as its organization, atomic number, electron configuration and use in predicting chemical reactivity are outlined.
This document provides instructions for writing formulas and naming different types of compounds. It explains that to write formulas, you must identify the elements and ions using the periodic table and write the cation first followed by the anion, balancing charges using the crisscross method. The three main types of compounds are ionic without transition metals, ionic with transition metals specified by Roman numerals, and covalent using prefixes and suffixes. Polyatomic ions also have set names and follow normal compound naming rules.
The document defines several key terms related to atoms and their structure. It explains that atoms are the fundamental building blocks of matter, consisting of protons, neutrons, and electrons. The nucleus of an atom contains protons and neutrons, while electrons orbit the nucleus in shells or orbitals. Valence electrons are located in the outermost orbital. The periodic table arranges the elements and groups them according to their chemical properties and number of valence electrons. Ions are atoms that have gained or lost electrons, giving them a positive or negative charge. Electronegativity refers to an atom's ability to attract electrons towards itself.

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

Immersive Learning That Works: Research Grounding and Paths ForwardLeonel Morgado
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
Describing and Interpreting an Immersive Learning Case with the Immersion Cub...Leonel Morgado
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
