Case Studies in Forensic Metallurgy
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

TV programs such as "Law and Order" show how forensic experts are called upon to give testimony that often determines the outcome of court cases. Engineers are one class of expert who can help display evidence in a new light to solve cases. In this seminar you will be part of the problem-solving process, working through both previously solved and unsolved cases. Each week we will investigate cases, from the facts that make up each side to the potential evidence we can use as engineers to expose culprits. The cases range from disintegrating airplane engines to gas main explosions to Mafia murders. This seminar will be full of discussions about the cases and creative approaches to reaching the solutions. The approach is hands-on so you will have a chance to participate in the process, not simply study it. Some background reading and oral presentation are required.

Creating Silver Nanoparticles
Read the Fine Print
Educational Use
Rating
0.0 stars

Students create silver nanoparticles using a chemical process; however, since these particles are not observable to the naked eye, they use empirical evidence and reasoning to discover them. Students first look for evidence of a chemical reaction by mixing various solutions and observing any reactions that may occur. Students discover that copper and tannic acids from tea reduce silver nitrate, which in turn form silver. They complete the reaction, allow the water to evaporate, and observe the silver nanoparticles they created in plastic dishes using a stereo microscope. Students iterate on their initial process and test to see if they can improve the manufacturing process of silver nanoparticles.

This survey chemistry course is designed to introduce students to the world of chemistry. In this course, we will study chemistry from the ground up, learning the basics of the atom and its behavior. We will apply this knowledge to understand the chemical properties of matter and the changes and reactions that take place in all types of matter. Upon successful completion of this course, students will be able to: Define the general term 'chemistry.' Distinguish between the physical and chemical properties of matter. Distinguish between mixtures and pure substances. Describe the arrangement of the periodic table. Perform mathematical operations involving significant figures. Convert measurements into scientific notation. Explain the law of conservation of mass, the law of definite composition, and the law of multiple proportions. Summarize the essential points of Dalton's atomic theory. Define the term 'atom.' Describe electron configurations. Draw Lewis structures for molecules. Name ionic and covalent compounds using the rules for nomenclature of inorganic compounds. Explain the relationship between enthalpy change and a reaction's tendency to occur.

Rating
0.0 stars

This course introduces the theory and technology of micro/nano fabrication. Lectures and laboratory sessions focus on basic processing techniques such as diffusion, oxidation, photolithography, chemical vapor deposition, and more. Through team lab assignments, students are expected to gain an understanding of these processing techniques, and how they are applied in concert to device fabrication. Students enrolled in this course have a unique opportunity to fashion and test micro/nano-devices, using modern techniques and technology.

Rating
0.0 stars

Through this lab, students are introduced to energy sciences as they explore redox reactions and how hydrogen fuel cells turn the energy released when hydrogen and oxygen are combined into electrical energy that can be read on a standard multimeter. They learn about the energy stored in bonds and how, by controlling the reaction, this energy can be turned into more or less useful forms.

Oxidation and reduction reactions power your phone and make it possible for your body to use the oxygen you inhale. We will learn about oxidation states (numbers), oxidation-reduction (redox) reactions, galvanic/voltaic cells, electrolytic cells, cell potentials, and how electrochemistry is related to thermodynamics and equilibrium.

0.0 stars

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Atherosclerosis and vascular injury are leading causes of cardiovascular disease worldwide Low-density lipoprotein (LDL) plays a key role in these diseases by inducing inflammation and oxidative stress Endothelial cells can repair blood vessels damaged by LDL But how endothelial cells mature and take on this task is unclear In a recent study, researchers examined the maturation and antioxidative activity of endothelial cells Molecular biology techniques revealed that the differentiation of endothelial cells was regulated by a microRNA molecule called miR-544 miR-544 inhibited the expression of genes involved in maintaining stem cell pluripotency Promoting endothelial cell maturation and vascular formation Transplanting endothelial cells expressing miR-544 also improved the outcome of oxidative stress injury in mice Although these studies must be further evaluated in humans The results suggest that targeting miR-544 may help with regeneration and repair of blood vessels after vascular injury Impr.."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.
