Bølgehøstning - fra elektrisk energi til mekanisk energi
Wave harvesting - from electric energy to mechanical energy
Dielektriske elastomerer er ifølge Anne det mest oplagte materiale at anvende netop til at indfri behovet for effektive og bæredygtige energikilder på grund af materialets enestående egenskaber.
According to Anne, dielectric elastomers are the most obvious material to use when it comes to fulfil the need for efficient and sustainable energy due to the unique properties of the material.
Dielektriske elastomerer udvider sig nemlig hvis de udsættes for et elektrisk felt og kan derfor omsætte energi fra en form til en anden: Enten som aktuator, fra elektrisk energi til mekanisk energi eller som en generator, fra mekanisk energi til elektrisk energi som det er tilfældet med bølgeenergihøstning.
If dielectric elastomers are exposed to an electric field, they expand and convert energy from one form to another: Either as actuator, from electric energy to mechanical energy or as a generator, from mechanical energy to electric energy, as the case with wave harvesting.
Snart vil SBM France lægge en 500 meter lang elastomerslange ud i havet ud fra Franskrigs kyst - fem meter under havets overflade.
Potentially, SBM France will place a 500-meter long elastomer tube of the coast of France - five meters below the bottom of the ocean.
Elastomerslangen vil fungere som en generator og deformeres af bølgernes kraft, og det er her at den mekaniske deformering omdannes til elektrisk energi.
What will happened is that the elastomer generator will deform by the huge wave powers, and the mechanical deformations will in return turn into electric energy.
Samtidigt slipper vi for alle ulemperne ved mekaniske generatorer idet elastomererne ikke larmer og er lette - til forskel fra mekaniske generatorer såsom motorer som både støjer og er enormt tunge.
At the same time, we avoid all the drawbacks of mechanical generators, as elastomers make no noise and are lightweight - unlike mechanical generators such as engines that are both noisy and extremely heavy.
Der er altså både tekniske og miljømæssige fordele ved at anvende disse kunstige muskler til at høste bølgeenergi.
Thus, there are both technical and environmental advantages of using these artificial muscles to harvest wave energy.
Håndteringen af materialet er dog stadig udfordrende, fortsætter hun.
However, handling the material is still not without its challenges, she continues.
I et tidligere projekt med Danfoss PolyPower har vi arbejdet direkte med at processere filmen med høj pålidelighed, og den viden bruges nu også i projektet med SBM”.
In an earlier project with Danfoss PolyPower we have worked directly on processing thin films with high reliability, and the gathered knowledge is now also used in the project with SBM”.
Anne Ladegaard Skov har nu afsluttet WEC projektet, og næste skridt for SBM France er at teste den 500 meter lange silikoneslange i det rigtige hav.
Anne Ladegaard Skov has completed her task in the WEC project, and next step for SBM France is to test the 500-meter long elastomer tube in the ocean.

Kvinder kan have bakterier i livmoderen, som kan få betydning for fostres immunsystem, viser ny forskning.
According to new research, women can have bacteria in their uteri which may have an impact on foetuses' immune systems.
Hidtil har æggestokke, æggeledere og livmoder været anset for at være et sterilt miljø.
Until now, the ovaries, Fallopian tubes, and the uterus have been considered sterile environments.
Resultatet er er offentliggjort i det videnskabelige tidsskrift Nature Communications.
The findings have been published in the scientific journal Nature Communications.
Forskningen er udført på Institute of Metagenomics, BGI-Shenzhen, Kina i samarbejde mellem Københavns Universitet, Nasjonalt Institutt for Ernæring- og Sjømatsforskning, Bergen, og DTU Bioengineering.
The research was carried out by the Institute of Metagenomics at BGI-Shenzhen, China, in collaboration with the University of Copenhagen, the National Institute of Nutrition and Seafood Research (NIFES) in Bergen, and DTU Bioengineering .
”En af de vigtige implikationer af vores fund er at de påviste mikroorganismer i kvindens underliv, kan tænkes at spille en rolle i udviklingen af fosterets immunsystem allerede under graviditeten.
“One of the important implications of our findings is that the micro-organisms which have been shown to exist in a woman's reproductive organs may play a role in the development of the foetus's immune system already during pregnancy.
Vores immunsystem er gearet til at genkende mikroorganismer, og hvis den mekanisme opbygges allerede i graviditeten, så åbner det for et helt nyt perspektiv i forhold til nye studier af kvindens rolle i programmeringen af barnets immunsystem i tidligt liv,” siger lektor Susanne Brix fra DTU Bioengineering, som har taget del i studiet.
Our immune systems are geared to recognizing micro-organisms, and if the mechanism already develops during pregnancy, it opens the door to a completely new perspective in relation to new studies of the woman's role in programming the child's immune system early on in life,” says Associate Professor Susanne Brix from DTU Bioengineering, who participated in the study.
Susanne Brix peger på, at forskningen kan danne grundlag for at udvikle nye test for sygdomme og lidelser i kvinders underliv, da de har påvist at visse bakterier dominerer ved sygdomme i de øvre dele af kvindens underliv og at disse ændringer også kan identificeres i prøver taget fra livmoderhalsen, der er nemmere at tilgå uden operation.
Susanne Brix points out that the research can provide a starting point for developing new tests for diseases and infections in the reproductive tract, as it has been shown that certain bacteria are dominant for certain diseases in the upper parts of the uterus, and that changes caused by these bacteria can also be identified in samples taken from the cervix, which is considerably easier to reach without surgery.
Stinkende slam bliver til energi og gødning
Stinking sludge into energy and fertilizer
DTU-startup udnytter slam fra fiskeopdræt og spildevand til at producere varme og næringsstoffer til markerne
DTU start-up utilizes sludge from fish farming and wastewater to produce heat and fertilizer.
Det er aktivt, gærer og indeholder meget vand - og det kan også være sundhedsfarligt.
It is active, ferments, has a high water content-and can be hazardous to health.
Kunderne står allerede i kø hos AquaGreen.
Customers are already queuing up at AquaGreen.
AquaGreens løsning består af et procesanlæg, der ved at koble tørring med damp og pyrolyse (spaltning af organiske forbindelser ved opvarmning uden ilt) kan udvinde naturlig gødning til landbruget og termisk energi til varmeforsyningen.
AquaGreen's solution consists of a processing plant which by means of steam drying and pyrolytic treatment (digestion of organic compounds by heating without oxygen) can extract natural fertilizers for agriculture and thermal energy for heating.
Alt sammen fra ildelugtende mudder.
All from foul-smelling mud.
De to venner udviklede en idé om at anvende det organiske materiale i slammet til at drive en tørrings- og forbrændingsproces på baggrund af pyrolyse.
The two friends developed the idea of using the organic material in the sludge to drive a drying and combustion process based on pyrolysis.
Pludselig kunne vi se, at vi kunne bruge nogle af de teknologier, som vi har arbejdet med de sidste 25 år.
Suddenly, we began to realize that we could use some of the technologies we had been working with over the past 25 years.
Procesanlægget har især skabt stor interesse i Norge, hvor man gradvist er ved at flytte dele af produktionen af laks fra havet op på land.
The process plant has generated particular interest in Norway, where fish farmers are gradually moving parts of their salmon farming from offshore to land-based production.
Samtidig har de norske myndigheder forbudt udledning af slam fra lakseopdræt direkte i havet, fordi det skaber store problemer.
At the same time, the Norwegian authorities have prohibited the direct emission of sludge from fish farms into the sea, as this creates huge environmental problems.
Et andet voksende marked er spildevandsslam, der i dag anvendes som gødning direkte på markerne i kommercielle landbrug.
Another growing market is wastewater sludge, which is currently used as fertilizer directly on fields in commercial agriculture.
En sådan lov kan sandsynligvis brede sig til hele EU og skabe et endnu større marked for innovative løsninger til at nedbryde de forurenende stoffer og muliggøre en sikker recirkulering af næringsstoffer.
Such legislation will most likely spread to the entire EU, thus creating an even bigger market for innovative solutions that break down the polluting substances and enable a secure recirculation of nutrients.
Ulrik Birk Henriksen, der er seniorforsker på DTU Kemiteknik, byder ind:
Ulrik Birk Henriksen, Senior Researcher at DTU Chemical Engineering, chimes in:
Normalt begynder man med at udvikle en teknik, som man derefter prøver at sælge til en virksomhed.
Normally, you start by developing a technique, which you then try to sell to a company.
I vores situation har vi kontakt til markedet fra begyndelsen.
We, however, began by going straight to the market.
Kunderne står i kø.
The customers are queueing up.
Det giver et helt andet drive.”

Matematiske modeller fra DTU Fødevareinstituttet er brugt til at udvikle nye fiskeprodukter med mindre salt og mere smag.
Mathematical models from the National Food Institute have been used to develop the recipes for a new range of fish products that contain less salt and more taste.
For folk med smag for konserverede fiskeprodukter - som rejer i lage eller gravad laks - gør en række nye saltreducerede produkter det nemmere at stille appetitten og samtidig efterleve begge kostråd.
For people with a taste for preserved fish products-such as prawns in brine or smoked salmon-a number of new salt-reduced products makes it easier to have their fill, while at the same time complying with both dietary recommendations.
Modellering forudsiger bakterievæksten
Modelling predicts bacterial growth
Salt har traditionelt været brugt til at konservere mange slags fiskeprodukter, fordi det hæmmer bakterievæksten og øger produkternes holdbarhed.
Salt has traditionally been used to preserve many types of fish products, because it inhibits bacterial growth and increases product shelf-life.
Hvis producenterne ændrer på saltindholdet, kan det derfor påvirke væksten af bakterier, som kan gøre varen dårlig eller farlig at spise.
Therefore, if manufacturers decide to change the salt content, it can affect the growth of bacteria, which can make the food go off or make it unsafe to eat.
I GUDP-projektet har DTU Fødevareinstituttets forskere udviklet nye modeller, som kan forudsige, hvordan en opskriftsændring påvirker væksten af Clostridium botulinum og pseudomonas bakterier i letkonserverede fiskeprodukter.
In the GUDP-project, researchers from the National Food Institute have developed models that can predict, how a recipe change will affect the growth of Clostridium botulinum and pseudomonas bacteria in lightly-preserved fish products.
Modellerne kan bruges sammen med instituttets eksisterende Food Spoilage and Safety Predictor (FSSP) program, som forudsiger væksten af den sygdomsfremkaldende mikroorganisme Listeria monocytogenes samt mælkesyrebakterier, der kan fordærve produkterne.
The models can be used in conjunction with the institute's existing Food Spoilage and Safety Predictor (FSSP) programme, which predicts the growth of the disease-causing microorganism Listeria monocytogenes as well as lactic acid bacteria, which can spoil the products.
Projektet har gjort det muligt for Royal Greenlands produktudviklere at forudsige, hvordan en ændring af opskriften vil påvirke bakterievæksten i et produkt.
The project has given Royal Greenland's product developers the ability to predict how a change to the recipe will affect bacterial growth in a product.
Derved er de blevet i stand til hurtigere at udvikle nye og sikre produkter, fordi de ikke har skullet bruge tid på kostbare forsøg.
As such they are able to quickly develop new and safe products, because they do not have to spend time on costly product trials.
De har i stedet brugt den viden, modellerne har givet dem, til at lave justeringer, indtil de har udviklet opskriften på et velsmagende produkt, som også er sikkert at spise.
Instead, they have used the information provided by the models to make adjustments, until they have developed the recipe for a tasty product that is also safe to eat.
Det er under projektet lykkedes Royal Greenland eksempelvis at udvikle koldtvandsrejer i lage og pasteuriserede stenbiderrogn med et 40% reduceret saltindhold.
Royal Greenland have for example managed to develop coldwater prawns in brine and pasteurized lumpfish roe that contain 40% less salt.
Siden FSSP-programmet blev introduceret i 1999 har mere end 10.000 brugere fra virksomheder, institutioner og myndigheder i mere end 100 forskellige lande taget det i brug.
Since the FSSP-programme was introduced in 1999 more than 10,000 people from companies, institutions and authorities in more than 100 countries have used it.

DTU Space er stærkt involveret i samarbejdet om den danske Ørsted satellit.
DTU Space is heavily involved in the joint project regarding the Danish Ørsted satellite.
Ørsted sender målinger af Jordens magnetfelt ned til forskerne, der bruger dem til at lave avancerede modeller af Jordens magnetfelt.
The satellite sends measurements of the Earth's magnetic field to scientists, who use these data to devise advanced models of the Earth's magnetic field.
Modellerne er udviklet af forskere fra DTU Space i samarbejde med NASA, og de bliver brugt over hele verden blandt andet til at søge efter olie og mineraler.
Developed by scientists at DTU Space in close cooperation with NASA, the models are used all over the world to search for oil and minerals.
Instituttet står desuden i spidsen for den fælles europæiske mission Swarm, der skal måle Jordens magnetfelt med hidtil uset præcision.
Moreover, the Institute is leading the joint European Swarm mission, whose objective is to measure the Earth's magnetic field with greater accuracy than ever before.
Swarm består af tre satellitter, der skal arbejde sammen om at måle magnetfeltet.
Swarm consists of three satellites that work in unison to measure the magnetic field.
Konstellationen af tre satellitter øger nøjagtigheden på målingerne med op til ti gange i forhold til tidligere, enlige satellitter, der har målt magnetfeltet.
The constellation of three satellites provides measurements of the magnetic field that are almost ten times as accurate as previous measurements taken by lone satellites.
DTU Space har udviklet de magnetometre, der skal udføre selve målingerne af magnetfeltet på Swarm.
DTU Space has developed the magnetometers aboard the Swarm mission which will record the measurements of the magnetic field.
Magnetometrene er videreudviklinger af de magnetometre, der var ombord på satellitterne Ørsted, SAC-C og CHAMP, og de gode erfaringer fra tidligere missioner har spillet en vigtig rolle i udviklingen af magnetometrene til Swarm.
The magnetometers are further refinements of those used aboard the Ørsted, SAC-C and CHAMP satellites, and the positive experience from previous missions has played an important role in developing the magnetometers destined for Swarm.
Fakta om Jordens magnetfelt
Facts on Earth's magnetic field
Når magnetfeltet i et område pludseligt bliver svagt, kan flere ladede partikler trænge igennem og gøre skade på både satellitter og passagerer i højtflyvende fly.
When the magnetic field in an area suddenly becomes weak, charged particles may penetrate the field and harm both satellites and passengers in high-flying aeroplanes.
Modified salinity water flooding er et relativ billig mulighed, da det ikke kræver dyr infrastruktur.
Modified salinity water flooding is relatively cheap, as it does not need expensive infrastructure.
Det største problem er, at selvom metoden er en succes i laboratorierne og felten, så er mekanismerne bag stadig ukendt.
The major problem is that although it is successfully tested in the lab, pilot, and field trials, its mechanism is still unknown.
Både industri- og universitetsforskere deltog med fælles fodslag i modified salinity water flooding.
Both industry and academic researchers participated with the common ground of modified salinity water flooding as a pull factor.
”Jeg kom i dag, fordi jeg aktivt arbejder med dette område.
“I came here today because I am actively working on this subject.
Indtil videre har emnerne været interessante og udfordrende, men jeg ville ønske, at der var endnu mere tid til diskussionerne, da det er dem, der skaber grundlag for ny forskning” siger workshoptaler Dr. Hassan Mahani fra Shell.
So far, the topics have been interesting and challenging, but I would like even more time for discussions as that provides the basis for new research,” says speaker Dr. Hassan Mahani from Shell.
Formålet var at invitere en forskelligartet gruppe af forskere, der har studeret forskellige mekanismer i modified salinity water flooding.
The aim was to invite a diverse group of researchers who have studied different suggested mechanisms for the modified salinity water flooding.
Denne diversitet resulterede i, at de 9 workshoptalere angreb emnet modified salinity water flooding meget forskelligt som: hvorfor modeller er vigtige og kan understøtte beslutninger, hvilke udfordringer, der ofte er i laboratorierne, hvordan forståelsen af forskningsfeltet har ændret sig over tid og erfaringsudveksling.
This diversity resulted in the 9 speakers interpreting the subject Modified Salinity Water Flooding in many different ways such as: why models are important and can support decisions, which difficulties are common in the labs, how the understanding of this research area has changed over time and the exchange of experiences.

We also planned to extend our collaborations with other researchers,” says researcher Ali Akbar Eftekhari, Danish Hydrocarbon Research and Technology Centre.
”I dag har været et godt resume af, hvad mine kollager arbejder på, hvilket altid er spændende” Siger Dr. Hassan Mahani.

Salt og solvarme kan bruges som erstatning for fossile brændsler til opvarmning af huse.
Salt and solar heat can be used to replace fossil fuels for heating houses.
Ny ph.d.-afhandling tester to prototyper, hvor solenergi lagres i en saltforbindelse og kan udløses efter behov.
A new PhD thesis is testing two prototypes, where solar energy is stored in a salt compound and can be released when needed.
Der er et kæmpe potentiale i at bruge vedvarende energikilder som eksempelvis solenergi til at opvarme bygninger.
There is a huge potential in using renewable energy sources such as solar energy to heat buildings.
Alligevel sker opvarmning af langt de fleste bygninger ved hjælp af fossile brændsler, hvilket udleder drivhusgasser til skade for miljø og klima.
Still, the vast majority of buildings are heated by fossil fuels emitting greenhouse gases harmful to the environment and climate.
For at kunne bruge vedvarende energi som effektiv energikilde er det nødvendigt at kunne lagre den overskudsenergi, som produceres, så den kan bruges senere hen.
In order to use renewable energy as an efficient source of energy, it is necessary to store the excess energy produced, so it can be used later on.
Netop lagringen er en udfordring, som forskere og virksomheder i mange år har kløet sig i nakken over.
Exactly storage is a challenge that researchers and companies have ruminated about for many years.
Ph.d.-studerende Mark Dannemand fra DTU Byg har taget udfordringen op i sin afhandling.
PhD student Mark Dannemand from DTU Civil Engineering has taken up the challenge in his thesis.
Derfor er der behov for at udvikle en effektiv måde at lagre energien på, så vi hurtigt kan få adgang til den, når behovet opstår."
Therefore there is a need to develop an efficient way to store energy, so we can access it when the need arises."
Derfor er der behov for at udvikle en effektiv måde at lagre energien på, så vi hurtigt kan få adgang til den, når behovet opstår,” siger Mark Dannemand.
Therefore there is a need to develop an efficient way to store energy, so we can access it when the need arises, "says Mark Dannemand.
Håndvarmere som inspiration
Inspiration from hand-warmers
Idéen bag Mark Dannemands forskning er inspireret af håndvarmere, som har været på markedet siden 1970'erne.
The idea behind Mark Dannemand's research was inspired by hand-warmers, which have been on the market since the 1970's.
Håndvarmerne indeholder en saltforbindelse, koges i ti minutter og er herefter opladet med varme, som kan udløses, når behovet opstår.
The hand-warmers contain a salt compound, are boiled for ten minutes and then charged with heat, which can be triggered when the need arises.
Der sker ved at knække en metalplade inden i håndvarmerne, som starter en kemisk proces, der udleder varme.
The heat is released by breaking a metal plate inside the hand-warmers, which initiates a chemical process, and heat is emitted.
”Princippet bag håndvarmerne har været kendt længe, men der er aldrig nogen, der har efterprøvet det i stor skala i praksis før.
"The principle behind the hand-warmers has been known for a long time, but no one has ever tested the principle in a large scale in practice before.
Derfor har jeg og mine kolleger udviklet en prototype på en varmelagringsenhed, som jeg tester i min afhandling,” fortæller Mark Dannemand.
Therefore, I and my colleagues developed a prototype of a heat storage device which I am testing in my thesis, "tells Mark Dannemand.
Varmelagringen i Mark Dannemands forsøg foregår ved at smelte salthydratet natriumacetat trihydrat ved 58 grader celsius.
The heat storage in Mark Dannemand's tests is conducted by melting the salt compound Sodium Acetate Trihydrate at 58 degrees Celsius.
Denne proces kaldes underafkøling.
This process is known as supercooling.
