Chemistry of Breadmaking: An Introduction to the Science of Baking
 
05:30
Produced by Skylar Goldman; created 5/4/14 This video is intended to help people interested in chemistry learn something about baking, and those interested in baking learn a little bit about the science behind baking. The target audience is students in either chemistry or baking courses at the middle or high school level, as well as adult hobbyists in either area. This video was produced for the course CMS.333, Producing Educational Videos, at MIT in Spring 2014. As both a chemical engineering student and amateur baker, I was excited to produce a video at this intersection.

Introduction to Electrochemistry
 
16:37
Everything you need to know about Electrochemistry. Electrochemistry is the relationship between electricity and chemical reactions. There are two ways that electricity and chemical reactions interact: certain chemical reactions can create electricity, and electricity can force certain chemical reactions to happen that wouldn't happen otherwise. We'll look at two very common examples in electrochemistry. We'll see how a galvanic or voltaic cell uses a chemical reaction to create electricity, and we'll see how electrolysis uses electricity to cause water to decompose into hydrogen and oxygen gas. We'll also look at the list of Standard Reduction Potentials, to figure out what chemical reactions will happen on their own (are spontaneous) are can create electricity, and which will not happen on their own (are not spontaneous) and require electricity to happen.

Wastewater treatment process overview
 
18:50
This lecture explains about the Wastewater treatment process and industrial wastewater management with sewage treatment. http://shomusbiology.weebly.com/ Download the study materials here- http://shomusbiology.weebly.com/bio-materials.html Sewage treatment is the process of removing contaminants from wastewater and household sewage, both runoff (effluents), domestic, commercial and institutional. It includes physical, chemical, and biological processes to remove physical, chemical and biological contaminants. Its objective is to produce an environmentally safe fluid waste stream (or treated effluent) and a solid waste (or treated sludge) suitable for disposal or reuse (usually as farm fertilizer). Using advanced technology it is now possible to re-use sewage effluent for drinking water, although Singapore is the only country to implement such technology on a production scale in its production of NEWater.[2] Source of the article published in description is Wikipedia.

What is Automation?

✅ C'mon over to https://realpars.com where you can learn PLC programming faster and easier than you ever thought possible! ========================== ✅ Check out the full blog post over at https: https://realpars.com/what-is-industrial-automation/ ========================== You’re sleepy, you wake in the middle of the night to get a drink. On your way to the kitchen, you stub your toe on a chair, kick the dog's water bowl which spills water all over the tile floor. You search for the light switch, slipping on the spilt water and fall on your, well, you know. How many times have you wished that this late night venture of searching for the light switch could be automated? Meaning, you just want to walk into the kitchen and the light will turn on all on its own. And of course, when you are finished and leave the room, the light should turn off as well. Well, an automatic process such as this is not unlike the factory floor and the concept of automation or industrial automation. This video discusses manual processes versus automated processes. The manual process being fumbling around in the kitchen searching for that illusive light switch and the automatic process of the light turning on automatically when you enter the room. The video will then bring those examples to the factory floor which will give you an in-depth look at the world of industrial automation. Let’s learn something! ========================== Missed our most recent videos?

High Performance Liquid Chromatography (HPLC) is a form of column chromatography that pumps a sample mixture or analyte in a solvent which is known as the mobile phase at high pressure through a column with chromatographic packing material known as stationary phase. The sample is carried by a moving carrier gas stream of helium or nitrogen. HPLC has the ability to separate, and identify compounds that are present in any sample that can be dissolved in a liquid in trace concentrations as low as parts per trillion. Because of this versatility, HPLC is used in a variety of industrial and scientific applications, such as pharmaceutical, environmental, forensics, and chemicals. Sample retention time will vary depending on the interaction between the stationary phase, the molecules being analyzed, and the solvent, or solvents used. As the sample passes through the column it interacts between the two phases at different rate, primarily due to different polarities in the analytes. Analytes that have the least amount of interaction with the stationary phase or the most amount of interaction with the mobile phase will exit the column faster. This lecture explains the following things about Hplc chromatography - 1. Hplc chromatography principle 2. Hplc chromatography instrumentation 3. Hplc chromatography types High-Performance Liquid Chromatography - Other HPLC Types Ultra High Performance Liquid Chromatography (uHPLC): Where standard HPLC typically uses column particles with sizes from 3 to 5µm and pressures of around 400 bar, uHPLC use specially designed columns with particles down to 1.7µm in size, at pressures in excess of 1000 bar. The main advantage of an uHPLC is speed. These systems are faster, more sensitive, and rely on smaller volumes of organic solvents than standard HPLC, resulting in the ability to run more samples in less time.

034 - Electrochemistry In this video Paul Andersen explains how electrochemical reactions can separate the reduction and oxidation portions of a redox reactions to generate (or consume) electricity. The half reactions can be analyzed to determine the potential of either a galvanic (voltaic) or an electrolytic cell. The reduction takes place at the cathode and the oxidation takes place at the anode. Do you speak another language?

NMR spectroscopy
 
30:56
NMR spectroscopy lecture by Suman Bhattacharjee - This lecture explains about the NMR spectroscopy basics. Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy, is a research technique that exploits the magnetic properties of certain atomic nuclei. It determines the physical and chemical properties of atoms or the molecules in which they are contained. It relies on the phenomenon of nuclear magnetic resonance and can provide detailed information about the structure, dynamics, reaction state, and chemical environment of molecules. The intramolecular magnetic field around an atom in a molecule changes the resonance frequency, thus giving access to details of the electronic structure of a molecule. Most frequently, NMR spectroscopy is used by chemists and biochemists to investigate the properties of organic molecules, although it is applicable to any kind of sample that contains nuclei possessing spin. Suitable samples range from small compounds analyzed with 1-dimensional proton or carbon-13 NMR spectroscopy to large proteins or nucleic acids using 3 or 4-dimensional techniques. The impact of NMR spectroscopy on the sciences has been substantial because of the range of information and the diversity of samples, including solutions and solids. NMR spectra are unique, well-resolved, analytically tractable and often highly predictable for small molecules. Thus, in organic chemistry practice, NMR analysis is used to confirm the identity of a substance. Different functional groups are obviously distinguishable, and identical functional groups with differing neighboring substituents still give distinguishable signals. NMR has largely replaced traditional wet chemistry tests such as color reagents for identification. A disadvantage is that a relatively large amount, 2–50 mg, of a purified substance is required, although it may be recovered. Preferably, the sample should be dissolved in a solvent, because NMR analysis of solids requires a dedicated MAS machine and may not give equally well-resolved spectra. The timescale of NMR is relatively long, and thus it is not suitable for observing fast phenomena, producing only an averaged spectrum. Although large amounts of impurities do show on an NMR spectrum, better methods exist for detecting impurities, as NMR is inherently not very sensitive. NMR spectrometers are relatively expensive; universities usually have them, but they are less common in private companies. Modern NMR spectrometers have a very strong, large and expensive liquid helium-cooled superconducting magnet, because resolution directly depends on magnetic field strength. Less expensive machines using permanent magnets and lower resolution are also available, which still give sufficient performance for certain application such as reaction monitoring and quick checking of samples. There are even benchtop NMR spectrometers. This important and well-established application of nuclear magnetic resonance will serve to illustrate some of the novel aspects of this method. To begin with, the nmr spectrometer must be tuned to a specific nucleus, in this case the proton. The actual procedure for obtaining the spectrum varies, but the simplest is referred to as the continuous wave (CW) method. A typical CW-spectrometer is shown in the following diagram.

How the Leaning Tower of Pisa Was Saved: Crash Course Engineering #40
 
09:54
This week we’re going underground to explore geotechnical and seismic engineering. We’ll look at how structures connect to the ground and transmit loads through their foundations, and how those foundations need to provide a high bearing capacity. We’ll see how properties of the soil, like shear strength, affect bearing capacity. We’ll also consider happens when the ground experiences stress from seismic activity and how seismic engineers work to counteract those effects.

Gas Chromatography | working principle and instrumentation lecture
 
26:02
Gas chromatography lecture - This chromatography lecture explains about the instrumentation, principle of gas chromatography. Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture (the relative amounts of such components can also be determined). In some situations, GC may help in identifying a compound. In preparative chromatography, GC can be used to prepare pure compounds from a mixture. This lecture will explain the principle of gas chromatography and the instrumentation and uses of gas chromatography. In gas chromatography, the mobile phase (or "moving phase") is a carrier gas, usually an inert gas such as helium or an unreactive gas such as nitrogen. Helium remains the most commonly used carrier gas in about 90% of instruments although hydrogen is preferred for improved separations.The stationary phase is a microscopic layer of liquid or polymer on an inert solid support, inside a piece of glass or metal tubing called a column (an homage to the fractionating column used in distillation). The instrument used to perform gas chromatography is called a gas chromatograph (or "aerograph", "gas separator"). Gas chromatography is in principle similar to column chromatography (as well as other forms of chromatography, such as HPLC, TLC), but has several notable differences. First, the process of separating the compounds in a mixture is carried out between a liquid stationary phase and a gas mobile phase, whereas in column chromatography the stationary phase is a solid and the mobile phase is a liquid. (Hence the full name of the procedure is "Gas–liquid chromatography", referring to the mobile and stationary phases, respectively.) Second, the column through which the gas phase passes is located in an oven where the temperature of the gas can be controlled, whereas column chromatography (typically) has no such temperature control. Finally, the concentration of a compound in the gas phase is solely a function of the vapor pressure of the gas. Gas chromatography is also similar to fractional distillation, since both processes separate the components of a mixture primarily based on boiling point (or vapor pressure) differences. Gas chromatography is also sometimes known as vapor-phase chromatography (VPC), or gas–liquid partition chromatography (GLPC). These alternative names, as well as their respective abbreviations, are frequently used in scientific literature. Strictly speaking, GLPC is the most correct terminology, and is thus preferred by many authors. In most modern GC-MS systems, computer software is used to draw and integrate peaks, and match MS spectra to library spectra. Gas Chromatography is used extensively in forensic science.

Absorption and Adsorption - Definition, Difference, Examples
 
04:54
Absorption And Adsorption Adsorption is the adhesion of molecules of gas, liquid, or dissolved solids to a surface. This process creates a film of the adsorbate (the molecules or atoms being accumulated) on the surface of the adsorbent. It differs from absorption, in which a fluid permeates or is dissolved by a liquid or solid. The term sorption encompasses both processes, while desorption is the reverse of adsorption. Similar to surface tension, adsorption is a consequence of surface energy. In a bulk material, all the bonding requirements (be they ionic, covalent, or metallic) of the constituent atoms of the material are filled by other atoms in the material. However, atoms on the surface of the adsorbent are not wholly surrounded by other adsorbent atoms and therefore can attract adsorbates. The exact nature of the bonding depends on the details of the species involved, but the adsorption process is generally classified as physisorption (characteristic of weak van der Waals forces) or chemisorption (characteristic of covalent bonding). Adsorption is present in many natural physical, biological, and chemical systems, and is widely used in industrial applications such as activated charcoal, capturing and using waste heat to provide cold water for air conditioning and other process requirements (adsorption chillers), synthetic resins, increase storage capacity of carbide-derived carbons for tunable nanoporous carbon, and water purification. Adsorption, ion exchange, and chromatography are sorption processes in which certain adsorbates are selectively transferred from the fluid phase to the surface of insoluble, rigid particles suspended in a vessel or packed in a column.
