The job of a synthetic chemist is akin to that of an architect. While the architect could actually see the building he is constructing, a molecular architect called chemist is handicapped by the fact that the molecule he is synthesizing is too small to be seen. With such a limitation, how does he ‘see’ the developing structure? For this purpose, a chemist makes use of spectroscopic tools. How does he cut, tailor and glue the components on a molecule that he cannot see? For this purpose chemists have developed molecular level tools called Reagents and Reactions. How does he clean the debris and produce pure molecules? This feat is achieved by crystallization, distillation and extensive use of Chromatography techniques. A mastery over several such techniques enables the molecular architect (popularly known as organic chemist) to achieve the challenging task of synthesizing the myriade of molecular structures encountered in Natural Products Chemistry, Drug Chemistry and modern Molecular Materials. In this task, organic chemists are further guided by several ‘thumb rules’ that chemists have evolved over the past two centuries.

Dissolved ions are present in all freshwater systems, but humans can change the chemical composition of freshwater in several ways. In this activity, students will examine the concentration of major ions in freshwater systems over time and reason about potential drivers of these changes.

In this activity, students use the virtual lab to create stock solutions starting from solid salts. Students must first calculate the correct amount of solid to make the solution. Next, they prepare the solution using the appropriate glassware. Students can check to see if their procedure was correct using the concentration viewer in the solution info panel.

A class on setting up and managing research materials; caring for digital files to enable collaboration, sharing, and re-use; and helpful software/digital tools for organizing personal research files.

User-friendly Geographic Information Systems (GIS) is the common thread of this collection of presentations, and activities with full lesson plans. The first section of the site contains an overview of cartography, the art of creating maps, and then looks at historical mapping platforms like Hypercities and Donald Rumsey Historical Mapping Project. In the next section Google Earth Desktop Pro is introduced, with lessons and activities on the basics of GE such as pins, paths, and kml files, as well as a more complex activity on "georeferencing" an historic map over Google Earth imagery. The final section deals with ARCGIS Online and StoryMaps with tutorials, basic exercises on pins, paths, and CSV import, and a lesson plan for creating a research project presentation on an historic building in StoryMaps. In addition to an xml file that has been uploaded here to Academic Works, the module is also a live website at https://libguides.brooklyn.cuny.edu/cs-x. The site was created with Libguides software, and is a Community Libguide that can be reused and imported into other LibGuides sites. The website also contains links to two live StoryMaps, one on an Introduction to ARCGIS StoryMaps (https://arcg.is/1SX1zH), and the second, a model assignment on the history of the Fairway building in Red Hook, Brooklyn (https://arcg.is/1nbHP).

Mathematics for Biomedical Physics is an open textbook, published by the Wayne State University Library System, geared to introduce several mathematical topics at the rudimentary level so that students can appreciate the applications of mathematics to the interdisciplinary field of biomedical physics. Most of the topics are presented in their simplest but rigorous form so that students can easily understand the advanced form of these topics when the need arises. Several end-of-chapter problems and chapter examples relate the applications of mathematics to biomedical physics. After mastering the topics of this book, students would be ready to embark on quantitative thinking in various topics of biology and medicine.

You and a friend are hiking the Appalachian Trail when a storm comes through. You stop to eat, but find that all available firewood is too wet to start a fire. From your Chem 106 class, you remember that heat is given off by some chemical reactions; if you could mix two solutions together to produce an exothermic reaction, you might be able to cook the food you brought along for the hike. Luckily, being the dedicated chemist that you are, you never go anywhere without taking along a couple chemical solutions called X and Y just for times like this. The Virtual Lab contains solutions of compounds X and Y of various concentrations.

As an analytical chemist at a company developing new engine coolants your task is to determine the heat capacity of a newly developed product and then to determine if its heat capacity is greater of less than that of ethylene glycol.

This is a calculus-based book meant for the first semester of the type of freshman survey course taken by engineering and physical science majors. A treatment of relativity is interspersed with the Newtonian mechanics, in optional sections. The book is designed so that it can be used as a drop-in replacement for the corresponding part of Simple Nature, for instructors who prefer a traditional order of topics. Simple Nature does energy before force, while Mechanics does force before energy. Simple Nature has its treatment of relativity all in a single chapter, rather than in parallel with the development of Newtonian mechanics.

In Mechanics and Relativity, the reader is taken on a tour through time and space. Starting from the basic axioms formulated by Newton and Einstein, the theory of motion at both the everyday and the highly relativistic level is developed without the need of prior knowledge. The relevant mathematics is provided in an appendix. The text contains various worked examples and a large number of original problems to help the reader develop an intuition for the physics. Applications covered in the book span a wide range of physical phenomena, including rocket motion, spinning tennis rackets and high-energy particle collisions.

Mesoscopic physics is the area of Solid State physics that covers the transition regime between macroscopic objects and the microscopic, atomic world. The main goal of the course is to introduce the physical concepts underlying the phenomena in this field.

Students will learn about a technique called microarray that measures changes in mRNA

You probably remember the mole from high school chemistry, but do you remember why it is useful to chemists? The goal of the following video is to give the "big picture" of the mole and its applications; information on how to use the mole in calculations can be found in another tutorial. Throughout this course, we will use the term "molecular weight" to refer to the mass of a mole of a substance (for instance, the molecular weight of oxygen (O2) is 32 g/mol). Recent textbooks refer to this as "molar mass" to emphasize (i) that this term refers to the mass, not the weight, of substance, and (ii) that the quantity refers to a mole of a substance, not a single molecule. "Molecular weight" may be less precise, but it remains the term that most practicing chemists use in the laboratory. For this reason, we continue to use "molecular weight" in this course.

Short Description:
Organic chemistry is the chemistry of carbon and carbon-containing compounds. Since the core structural, catalytic, information storage, and retrieval systems of organisms are carbon-based macromolecules, organic chemistry is of direct relevance to the life sciences. Just as importantly, the properties of carbon make possible an amazing range of molecules with unique properties, from small molecules to complex plastics and even more complex biomolecules.

Long Description:
The essence of organic chemistry is how carbon atoms interact with other atoms and groups of atoms to produce an astounding array of complex and interesting molecules. The basics of bonding and intermolecular interactions are introduced in the general chemistry version of CLUE (Chemistry, Life, the Universe & Everything), along with how the structure of a molecule affects its properties, how the energy changes associated with chemical and physical changes can be predicted and explained, and how chemical systems can be stabilized or perturbed by changing conditions. These four core ideas (structure-property relationships, bonding and interactions, energy, and stability, and change) are continued on into OCLUE and are deepened and expanded as we discover and explain ever more complex chemical systems.
