Differential scanning calorimetry (DSC) is a technique used to analyze thermal transitions in materials. There are two main types of DSC instruments: heat-flux DSC and power-compensated DSC. Heat-flux DSC measures the difference in heat flow into the sample and reference, while power-compensated DSC maintains the sample and reference at equal temperatures while measuring the power difference required. DSC can be used to analyze properties such as glass transitions, melting points, crystallization kinetics, and heat of reactions. It has applications in fields such as materials science, polymers, and pharmaceuticals.
This document discusses different thermal analysis techniques including thermo gravimetric analysis (TGA), differential thermal analysis (DTA), and differential scanning calorimetry (DSC). TGA measures mass changes as a function of temperature. DTA measures the temperature difference between a sample and reference as they are heated. DSC directly measures heat flows into or out of a sample during transitions. The techniques are used to study physical and chemical transitions in materials and have applications in fields like polymers, food, pharmaceuticals, and ceramics for analyzing composition, stability, phase transitions, and melting/boiling points.
Thermogravimetric analysis (TGA) measures the change in mass of a sample as it is heated. In a TGA experiment, a sample is placed in a furnace that increases in temperature at a controlled rate while the sample mass is continuously monitored with a microbalance. A TGA curve plots the percentage mass change over time or temperature. TGA can be used to determine decomposition temperatures of materials, measure purity and stability, and study thermal decomposition mechanisms of organic, inorganic, and polymeric compounds.

The document discusses solvent selection for NMR spectroscopy. For proton NMR, deuterated solvents are preferred to avoid interference from solvent protons. Common deuterated solvents include deuterated water and chloroform. For carbon-13 NMR, any solvent can be used as the dominant carbon-12 isotope has no spin and does not appear in NMR. Deuterated solvents are still preferred to avoid interference from solvent protons. Trifluoroacetic acid can also be used as a solvent for proton NMR due to its proton signal appearing far downfield from the region of interest.

Both techniques can detect physical and chemical changes that occur in samples through endothermic or exothermic events as temperature is changed. DSC is now more commonly used as it provides calorimetric measurements of energy changes during transitions.

LITERACY SLIDES (click here to get full screen)lorilisi
There is no agreed upon definition of literacy as understandings of it are socially constructed. Literacy involves reading, writing, communicating, and gaining knowledge and can take many forms including cultural, informational, financial, media, scientific, critical, and digital literacies. Literacy is an ongoing social practice that allows for freedom, social action, and rereading of the world from different perspectives.
The document discusses the relationship between breaking points, turning points, and comfort zones. It shares the author's personal experience of facing challenges in school that became a breaking point, but led to a turning point. The author decided to be responsible for their actions and not take shortcuts to success. They learned breaking points can become turning points if one maintains determination. Understanding one's weaknesses and using them as stepping stones is important. Breaking points do not have to defeat people, but can propel them forward if they refuse to give up or blame external factors.

More than twenty years ago, Robert Croshon, an elderly friend of Frye Gaillard's, told him the story of Croshon's ancestor, Gilbert Fields, an African-born slave in Georgia who led his family on a daring flight to freedom.
Fields and his family ran away intending to travel north, but clouds obscured the stars and when morning came Fields discovered they had been running south instead. They had no choice but to seek sanctuary with the Seminole Indians of Florida and later a community of free blacks in Mobile.
With Croshon's blessing, Gaillard has expanded this oral history into a novel for young readers, weaving the story of Gilbert Fields through the nearly forgotten history of the Seminoles and their alliance with runaway slaves. As Gaillard's narrative makes clear, the Seminole Wars of the 1830s, in which Indians fought side by side with former slaves, represents the largest slave uprising in American history.

Just sitting there writing notes

you like other kids. They’re

they feel like you’re doing

13. Reading as Maori
Patricia Grace on when books are harmful for indigenous
readers, quoted in Anne Milne
Linda Smith (1999, p.33) directly implicates schools in the
redefinition of indigenous worlds and discusses the dangers
implicit in reading and writing. She cites Patricia Grace’s (1985)
assertion that “books are dangerous” to indigenous readers when
(1) they do not reinforce our values, actions, customs, culture and
identity; (2) when they tell us only about others they are saying
that we do not exist; (3) they may be writing about us but they are
writing things that are untrue; and (4) they are writing about us
but saying negative and insensitive things which tell us we are not
good (Smith, p.35).

Editor's Notes
How does this compare to what happens for Maori at Manawatu now?
Important to feel safe talking about race.
What do these things look like for Maori learners? How do they get affirmation, what is their notion of purpose?
