Each year the world loses enough food to feed half a billion people to fungi the most destructive pathogens of plantsMycologist and TED Fellow Mennat El Ghalid explains how a breakthrough in our understanding of the molecular signals fungi use to attack plants could disrupt this interaction and save our crops.

Molecular distillation a powerful technology for obtaining tocopherols.

Excerpt Hear former professional basketball player and motivational speaker Chris Herren speaking about his recovery from drug addictionSince August of 2008 Herren has been drugfree and alcoholfree and has refocused his life to put his sobriety and family above all other things.

Feb 11 2019nbsp018332Evolution has developed very efficient molecular machines for example for producing energy through rotationHendrik Dietz would like to harness these concepts to build his own molecular motors.

If they have different boiling points you can use the process of distillationHere well see how to separate water ether and alcoholEducator Talks Learn how educators in your community can give their own TEDstyle talks Nominate Nominate educators to work with TEDEd Support.

In this work important results from simulations are presented showing the potentiality of the molecular distillation process for recovering vitamin E from vegetal oilsTwo types of molecular distillators are considered falling film and centrifugal.

May 13 2021nbsp018332Working of Molecular Distillation The vessel walls are heated suitably by a heating jacketThe feed flows down the walls and is spread to a film by the polytetrafluoroethylene PTFE wipers which move about 3 ms giving a film velocity of about 5 msDue to heat liquid film evaporates and vapors hit the condenser.

Molecular distillation became an important industry during the past fifteen years and has enabled many thermally sensitive materials to be prepared on a commercial scale but the development of stills appears now to have reached a restingpoint.

Molecular distillation is a type of shortpath vacuum distillation characterized by an extremely low vacuum pressure 001 torr or below which is performed using a molecular stillIt is a process of separation purification and concentration of natural products complex and thermally sensitive molecules for example vitamins and polyunsaturated fatty acids.

Molecular distillation Last updated February 28 2020Molecular distillation is a type of shortpath vacuum distillation characterized by an extremely low vacuum pressure 001 torr or below which is performed using a molecular still.

Wiped Film Distillation This variation of short path distillation can operate in batch or continuous modesWhile under vacuum the oil is introduced to the top of a heated vertical cylinderAs the oil enters the cylinder it encounters rotating wipers or rollers that create a thin film on the heated surface.

Molecular distillation was studied for the separation of tocopherols from soya sludge both experimentally and by simulation under different operating conditions with good agreementEvaporator temperatures varied from 100 degrees C to 160 degrees C and feed flow rates ranged from 0The process pressure was maintained at 10 6.

Molecular distillation was studied for the separation of tocopherols from soya sludge both experimentally and by simulation under different operating conditions with good agreementEvaporator temperatures varied from 100176C to 160176C and feed flow rates ranged from 0The process pressure was maintained at 10 −6 bar the.

Hendrik Dietz Molecular machines of the future.

Some common lifesaving medicines such as insulin are made of proteins so large and fragile that they need to be injected instead of ingested as pillsBut a new generation of medicine made from smaller more durable proteins known as peptides is on its wayIn a quick informative talk molecular engineer and TED Fellow Christopher Bahl.

The best TED Talks for addiction and recovery along with other powerful YouTube videos to play for clients in a treatment setting 8211 or for yourself or for anyone who desires to learn more about substance use.

The molecular distillation principle is based on the separation of different substancesIt is based on the variance in their volatilityIt happens when a material reaches its boiling pointThe process involves 5 steps in order to be complete and get the results that are necessary to make decisions.

Wiped film molecular stills on the other hand are designed to move the material downwards through the system in a thin sheet that is heated in a homogenous fashion providing optimized heat exposure time for all material.
