New Lund Nano Lab update Webbversion

NEWSLETTER FROM NANOSCIENCE AT LUND UNIVERSITY  |  JUNE 2017 Update on the Plans for the New Lund Nano Lab For the past  year, we have been actively working on the planning of our new, larger clean-room facility – the new Lund Nano Lab (LNL) – at Science Village Scandinavia (SVS). After analysis of expected local vibrations and magnetic fields, we have identified a suitable area within SVS, which is approximately 150 m from the planned tram station and close to MAX IV. Next to LNL, but in a separate building, you will find the pilot production facility ProNano. ProNano will be independent from Lund University, but will offer many fruitful interactions. The site for the new LNL is also next to the area where we hope that several of the divisions  currently contributing to NanoLund will be co-located in the future. The plans for the new LNL include a detailed equipment list and layout of the cleanroom, taking into consideration factors such as efficient work flow, noise reduction and safety. Equally important are the non-visible parts such as chemical and other storage, waste handling systems, transportation of goods, service areas etc.  A very important part of the process is to make the transition to the new location as smooth as possible. We have for instance considered the transportation to and from the lab until we all move closer so there will be available work areas in the vicinity of the lab and lockers to handle personal belongings and computers.  It is critical to minimize research interruptions, and we therefore aim to operate the old LNL as long as possible while ramping up operations in the new LNL. Still, there will be interruptions (probably during 2019-2020), but, we will do everything we can to keep everyone informed and to allow students and scientists to plan their research work accordingly. Many individuals are contributing to the planning work, including LNL’s reference and user groups and LNL staff. We thank everyone for their hard work and welcome all additional input. Anneli Löfgren and Maria Huffman leaders of the planning group

Nanotubes that build themselves Kenneth Wärnmark has been involved in a study which have succeeded in producing nanotubes from a single building block using so-called molecular self-recognition. The tube can also change shape depending on the surrounding environment. The results can contribute to the future development of transport channels for drugs through the cell membrane.

Cells grow more naturally in “spaghetti” Lund researchers involving NanoLund's Fredrik Johansson, have achieved good results with their three-dimensional fibre structures for cell culturing. If the new technique delivers what it promises, electrospinning will be able to provide new opportunities for both research and industry. With more natural cell cultures on which to conduct research, a number of biomedical research issues can be addressed in new ways.

Modern alchemy creates luminescent iron molecules Nature reports that the first iron-based molecule capable of emitting light has been made. This could contribute to the development of affordable and environmentally friendly materials for e.g. solar cells, light sources and displays. Through advanced molecular design, the NanoLund researchers have successfully manipulated the electronic properties of iron-based molecules so that they much better resemble the ruthenium-based substances.

Nanowire imaging by super resolution optical microscopy K Adolfsson, M Borgström and C Prinz from NanoLund, in collaboration with Nobel Prize winner Stefan Hell, have published that nanowires can be imaged using super resolution optical microscopy. GaInP nanowires were imaged using ground state depletion at a five fold resolution enhancement compared to confocal microscopy. This method is compatible with biological tissue imaging and is therefore promising for the investigations of cell-nanowire interactions. The Nano Letters article has DOI: 10.1021/acs.nanolett.7b00468 Material standing on edge for efficient solar cells Advanced Materials reports on a new structural organization using the promising solar cell material perovskite. The study shows that solar cells increase in efficiency thanks to the material’s ability to self-organise by standing on edge. The current research study deals with perovskite, a new and promising material in the context of solar cells.

Students competing in Ericsson Innovation Award 2017 Rapidus reports that a student team from the Engineering Nanoscience programme qualified for the semifinals of the Ericsson Innovation Award 2017 in competition with 900 other teams entering the competition from around the world. The student team competes with an idea to automatically lower the price of food as the expiration date comes closer. The date is stored in the bar code on the packaging, and the lower price can be read using an app or a scanner in the store. Opportunities for nanoscience using neutron sources In our educational seminar series Nanoscience for Dummies, an introductory lecture on opportunities for using neutrons for nanoscience, given by Peter Schurtenberger on May 17, attracted much interest. One of the outcomes were plans for initial experiments taking advantage of the highly controlled nanostructures that NanoLund can provide. SwedNESS kick-off The graduate school for neutron scattering (SwedNESS) kicked off at an event in Uppsala on May 16. Financed by SSF, SwedNESS’ goal is to educate 25 doctoral students as a base for Sweden's expertise in neutron scattering with respect to the ESS. Two of the first students have started at Lund University, including a project led by Tommy Nylander that has been ramped up by NanoLund funding. NanoLund Junior Scientist Ideas Awards 2017 NanoLund seed projects give junior scientists (PhD student and postdocs) the opportunity to propose and carry out new projects that are complementary to existing research directions in NanoLund. In the 2017 project call, ten projects were received and evaluated by a group of senior scientists and PhD students, with an emphasis on originality, feasibility and potential impact. Four projects were selected for funding by a one-time sum of 100000 SEK for research expenses: Atomic ordering in group III-V ternary semiconductor nanowires, by Hanna Kindlund, Postdoc at Solid State Physics Three dimensional imaging of proteins on nanowires by Stefán Bragi Gunnarsson, PhD student at Biochemistry and Structural Biology Nanowire-gas interaction: from surface site probes to sensors by Daniel Finkelstein-Shapiro, Postdoc at Chemical Physics Nanowires for efficient terahertz emission by Pierre-Adrien Mante, Postdoc at Chemical Physics The projects will be presented in the form of a NanoLund Junior Scientist Ideas Award at our annual meeting on September 7. Strengthening NanoLund's core values Our work to further develop and strengthen the culture we would like to have for NanoLund is nearing the end of it’s first phase. Starting with a voting process last autumn (with up to more than 90 responses per week), we chose three core values early this year. In discussion meetings led by NanoLund’s coordinators across all areas of NanoLund, we spent the spring fleshing out exactly what these values mean to us. Members of the NanoLund environment contributed more than 100 suggestions for how each of us can help strengthen these values. The result is a condensed description of how we jointly see the culture we would like to have, which we will launch at the Annual Meeting on September 7. Thank you all for your all-important engagement! NanoLund staff scientist: Estephania Lira At NanoLund we aim to have the highest levels of sophistication in the use of equipment and in experimental and theoretical methods. To achieve this it is crucial to have excellent senior-level technical staff who have a high level of skill, who work hands-on with PhD students and postdocs, and who help develop new methods and transfer expertise. The division of Synchrotron Radiation Research (SLF) operates as many as seven scanning probe microscopes that are heavily used for research projects within NanoLund. With the increasing size and complexity of the STM/AFM facility, Dr. Estephania Lira was hired 2014 as research engineer for maintaining the STM and AFM equipment. Since then she has extended the range of STM and AFM capabilities, and she has trained new M.Sc. and Ph.D. students in handling the microscopes. The presence of a research engineer also allows us to take on more projects with external companies. Estephania can help you getting started on STM/AFM, identifying if we have the right instrument and getting you in contact with other relevant experts at SLF if you need a more in-depth collaboration for your samples. To contact Estephania, send her an e-mail at: estephania.lira@sljus.lu.se Nanowire Week in Lund Nanowire Week is the merger of two well-established and highly successful annual workshops: NANOWIRES and the Nanowire Growth Workshop. It took place in Lund May 29-June 2, 2017 and was chaired by Kimberly Thelander. Nanowire Week covered all topics of nanowire-related research, from fabrication and fundamental properties to applications. With 340 participants it is the largest workshop entirely dedicated to this research field. Fjärde Uppgiften recently released an interview with Lars Samuelson on the beginning of a Swedish nanotechnology industry. The duration of the interview (in Swedish) is about 12 minutes. On the homepage you may also find older interviews with Lars Montelius (on lighting) and Heiner Linke (on how nanotechnology will change the world). Coming up
