What technical forces are shaping the modern world? Revolutionary developments in the union of chemistry and physics hold the key to solving unprecedented global problems; however, understanding the central role that chemistry and technical forces play in addressing these problems and shaping our modern world requires a grasp of fundamental concepts of energy and energy transformations. Physical sciences are fundamental to an understanding of worldwide energy sources and constraints, energy forecasts, the technology connecting energy and climate, and the role of modern materials science. In this course, you will study industrial advances in solar cells, energy storage, and molecular imaging, and how international policies relate to these innovations. You’ll learn the role of energy in climate change and exactly how irreversible global climate change causes sea levels to rise, storms to become more powerful, and how large scale shifts in the climate structure trigger water and food shortages, as well as how technology advances to address these global issues. PS11.1x: University Chemistry: Molecular Foundations and Global Frontiers is Part 1 of what will be a two-part course. Part 1 of this course will teach you the foundational principles of chemistry and energy: thermodynamics, entropy, free energy, equilibria, acid-base reactions, and electrochemistry. Instead of learning about these concepts in the abstract, case studies will be used to develop quantitative reasoning and to directly link these principles to current global strategies. There is also an optional textbook available for purchase as a supplement to the course.

The course introduces the three key spectroscopic methods used by chemists and biochemists to analyse the molecular and electronic structure of atoms and molecules. These are UV/Visible , Infra-red (IR) and Nuclear Magnetic Resonance (NMR) spectroscopies. The content is presented using short focussed and interactive screencast presentations accompanied by formative quizzes to probe understanding of the key concepts presented. Numerous exercises are provided to facilitate mastery of each topic. A unique virtual spectroscopic laboratory is made available to enable students to measure and analyse spectra online. Assessment is via summative quizzes completed during the course period.

“Syntheses for Life” will start with the Bohr model of hydrogen atom and discuss chemical evolution, protein synthesis and structure, photosynthesis, and Haber’s synthesis of ammonia. The course provides an overview of remarkable scientific discoveries. First, In 1913 Bohr showed that the hydrogen line spectrum can be explained based on the nuclear model of the atom and quantum theory. Bohr model introduced the concept of energy levels for electrons in an atom and led to wave mechanics and a full understanding of chemical bonding. We will then discuss how amino acids could be produced from methane, ammonia, water and hydrogen using electric discharge as a source of energy. Chromatographic separation of simple compounds will be demonstrated. The 1953 paper in Science by Miller will be the primary source material. Third, The central dogma in protein synthesis will be briefly described. The determination of the primary structure of insulin will be discussed using Sanger’s 1958 Nobel Lecture. Experimental techniques such as electrophoresis and mass spectrometry as well as X-ray crystallography will be highlighted. We focus on the chemical principles of oxidation and reduction in photosynthesis. Calvin’s 1961 Nobel Lecture explains the role of enzymes involved in the dark reaction. How plant life and animal life are coupled by photosynthesis and respiration will be emphasized. Finally, Haber’s synthesis of ammonia is on top of the list among scientific discoveries that saved most lives. How Haber successfully selected the right process conditions and the catalyst will be described using his 1918 Nobel Lecture. Ertl’s discovery of the mechanism of the iron catalyst will also be discussed.

During each module of this course, chefs reveal the secrets behind some of their most famous culinary creations — often right in their own restaurants. Inspired by such cooking mastery, the Harvard team will then explain the science behind the recipe. Topics will include: How molecules influence flavor The role of heat in cooking Diffusion, revealed by the phenomenon of spherification, the culinary technique pioneered by Ferran Adrià. You will also have the opportunity to become an experimental scientist in your very own laboratory — your kitchen. By following along with the engaging recipe of the week, taking precise measurements, and making skillful observations, you will learn to think like both a cook and a scientist. The lab is certainly one of the most unique components of this course — after all, in what other science course can you eat your experiments?

The use of fossil resources is a controversial topic and there is much scientific research to argue against their use for energy, chemicals, and in the production of almost every product. Because of this, we're seeing a huge shift towards sustainable biobased and renewable resources and away from fossil-based ones. In this new world, it's critical to know how to efficiently and effectively obtain valuable elements from biomass. Jointhis course and gain the latest academic knowledge on biorefinery which can be applied to their ongoing studies or to advance their careers. Just as the petrochemical refinery is a crucial part of the fossil-based industry,so is the biorefinery for the biobased industry. In a biorefinery, a complex biobased feedstock is separated and processed in such a way to maximize sustainability and application opportunities. Upon completing this course, you will understand the tools and techniques needed to efficiently disentangle, separate and convert different biomass based feedstocks into simpler (functional) components. First, you'll learn about available techniques and processes for biomass activation, disentanglement and separation. Next, you'll explore how to design a biorefinery taking into account feedstock and sustainable energy use and dive into: Mass and energy balances Design of biorefinery process units to obtain multiple products from one type of biomass How to recover energy and resources in the biorefinery system Evaluation of the designed system with respect to sustainability and economic criteria Evaluation of criteria for successful implementation This course is part of the MicroMasters programme in Chemistry and Technology for Sustainability : a series of 3 courses and a final capstone project designed to help you develop the skills needed to seize opportunities and embrace the transition from a fossil-based economy to a biobased one.It'sespecially valuable to those who have (or ambition to have) a career in industries such as: (bio)chemical industry, agrifood water companies, energy producers, logistics, and related (non-)governmental organizations.

This course is an introduction to high-throughput experimental methods that accelerate the discovery and development of new materials. It is well recognized that the discovery of new materials is the key to solving many technological problems faced by industry and society. These problems include energy production and utilization, carbon capture, tissue engineering, and sustainable materials production, among many others. This course will introduce the learner to a remarkable new approach to materials discovery and characterization: high-throughput materials development (HTMD). Engineers and scientists working in industry, academic or government will benefit from this course by developing an understanding of how to apply one element of HTMD, high-throughput experimental methods, to real-world materials discovery and characterization problems. Internationally leading faculty experts will provide a historical perspective on HTMD, describe preparation of ‘library’ samples that cover hundreds or thousands of compositions, explain techniques for characterizing the library to determine the structure and various properties including optical, electronic, mechanical, chemical, thermal, and others. Case studies in energy, transportation, and biotechnology are provided to illustrate methodologies for metals, ceramics, polymers and composites. The Georgia Tech Institute for Materials (IMat) developed this course in order to introduce a broad audience to the essential elements of the Materials Genome Initiative. Other courses will be offered by Georgia Tech through Coursera to concentrate on integrating (i) high-throughput experimentation with (ii) modeling and simulation and (iii) materials data sciences and informatics. After completing this course, learners will be able to • Identify key events in the development of High-Throughput Materials Development (HTMD) • Communicate the benefits of HTMDwithin your organization. • Explain what is meant by high throughput methods (both computational and experimental), and their merits for materials discovery/development. • Summarize the principles and methods of high throughput creation/processing of material libraries (samples that contain 100s to 1000s of smaller samples). • State the principles and methods for high-throughput characterization of structure. • State the principles and methods for high throughput property measurements. • Identify when high-throughput screening (HTS) will be valuable to a materials discovery effort. • Select an appropriate HTS method for a property measurement of interest. • Identify companies and organizations working in this field and use this knowledge to select appropriate partners for design and implementation of HTS efforts. • Apply principles of experimental design, library synthesis and screening to solve a materials design challenge. • Conceive complete high-throughput strategies to obtain processing-structure-property (PSP) relationships for materials design and discovery.
