Kind reminder about new program to improve fabrication quality at Birck
by Peroulis, Dimitrios 21 Mar '17

21 Mar '17

Dear all, This is just a kind reminder that we would like your input to the following program by Friday March 24th (the weekend is ok too). Thanks much to everyone who responded already. Best Dimitri From: Peroulis, Dimitrios Sent: Friday, March 3, 2017 10:02 AM To: 'bnc-all(a)ecn.purdue.edu' <bnc-all(a)ecn.purdue.edu> Subject: New program to improve fabrication quality at Birck - input requested by March 24 Dear all, In an effort to improve fabrication quality at Birck, we are starting a new program focused on process characterization, monitoring, and control. Essentially, we would like our engineering staff to help you achieve consistent and repeatable results by regularly running and characterizing your critical fabrication processes in the cleanroom. This could have multiple benefits: 1. Improved quality control and repeatability 2. Provides early warning for process and equipment problems 3. Effectively creating and maintaining process database and lab memory 4. Active engagement of engineering staff into research 5. Lowering fabrication cost and time for everyone This effort will be successful only with active participation of faculty and their research group. As a first step, we would like to invite each group to document the steps for a couple of critical processes they follow on a regular basis. For example, it could be a lithography process (document PR, recipes, measurement method), or an oxide deposition process (document sample preparation, deposition recipe, measurement method). In the beginning students/postdocs will be training engineering staff to run these processes. In the long run the staff members will run these on a regular basis and maintain a database. This will be a dynamic program with new processes being added and obsolete ones being retired on a regular basis. Priority will be given to processes that benefit multiple groups. Please send these processes to Ron and I by March 24, 2017 in a ppt format. After this, we will have a meeting to group these and discuss a plan to get started. We would very much welcome any thoughts and ideas you have on how to make this successful and improve everyone's fabrication results at Birck. Best, Dimitri ________________________________________________________________________________ Dimitrios Peroulis Professor, School of Electrical and Computer Engineering Deputy Director, Birck Nanotechnology Center Purdue University 1205 West State Street West Lafayette, IN 47907-2057 tel: (765) 494-3491 email: dperouli(a)purdue.edu<mailto:dperouli@purdue.edu> http://sites.google.com/site/peroulisteam/ ________________________________________________________________________________

Re: [BNC-all] UPDATE - URGENT - Emergency Shutdown Due to Loss Campus Steam -
by Voorhis, Mark L. 14 Mar '17

14 Mar '17

Update on campus steam. It appears that several boilers shutdown for unexplained reasons at the wade power plant allowing our incoming steam pressure to drop from 125psi to 15 psi in 30 minutes. Physical Facilities has restarted 7 boilers trying to recover steam pressure across campus. Our building is currently stable waiting for the steam pressure to return to normal. At this time we do not expect any interruption to ambient controls or hazardous processes. Building systems should recover to normal operation in the next 2-3 hours given the present conditions. Thank you for your patience. From: BNC-all [mailto:bnc-all-bounces@ecn.purdue.edu] On Behalf Of Voorhis, Mark L.

The loss of steam during cold weather may result in shutting down all cleanroom and general laboratory air handling units losing temperature and humidity ambient control. This may also shut down all chemical exhaust systems and hazardous processes. We have implemented contingency plans to conserve steam the best we can. These changes may lead to the cleanroom going negative allowing dirty air to be pulled into the cleanroom so plan accordingly to protect any contamination sensitive research inside the cleanroom.

Especially in the context of the disease of cancer, isolation of rare cells from blood samples of patients is extremely important as it offers a glimpse into the tumor using a simple blood test. One important downstream application for such methods is testing of drugs in a personalized manner. One can isolate the tumor cells of a particular patient and find out which drugs are effective in killing these cells before trying drugs directly on the patient. However tumor cells are found in blood samples only in extremely small amounts. This is a challenge because one normally needs a lot of cells to test sufficient combinations and dosages of drugs. It is therefore important to culture the isolated cells and increase their number. While culturing the cells, it is important to mimic conditions that the cells experience in their natural environment as much as possible so that the resulting tests can correlate with realistic outcomes. This can best be achieved with 3D culture conditions where cells are suspended in a manner that surrounds them with tissue-like milieu, as opposed to 2D methods where cells attach to a flat surface, a condition that is not natural. We are collaborating with Drs. Lelièvre and Kwok to develop novel methods to culture single rare cells in a manner that allows high throughout analysis and testing. We expect that these studies will enhance our understanding of heterogeneity and pave the way to personalized therapy. Professor Çağrı A. Savran School of Mechanical Engineering School of Biomedical Engineering (by courtesy) School of Electrical and Computer Engineering (by courtesy) ________________________________ 3D in Focus Osteoarthritis is one of the leading causes of chronic disability for elderlies. One of the possible causes of the disease is synovial inflammation by macrophage activation. The objective of the article highlighted in this newsletter was to build and validate a 3D coculture system for osteoarthritis inflammation through paracrine interactions between chondrocytes and macrophages. Featured article: Satyavrata Samavedi, Patricia Diaz-Rodriguez, Joshua D. Erndt-Marino, and Mariah S. Hahn. A Three-Dimensional Chondrocyte-Macrophage Coculture System to Probe Inflammation in Experimental Osteoarthritis Tissue. Tissue Engineering: Part A 2017, 23: 101-114. In the transwell system, normal chondrocytes (NCs) cultured in the upper chamber and activated macrophages (AMs) cultured in the bottom chamber were both placed in a 3D environment by encapsulation within poly(ethylene glycol) diacrylate hydrogels. Increased levels of matrix metalloproteinases (MMPs) and proinflammatory cytokines that are associated with early stages of osteoarthritis were observed in NCs cells in the coculture system. Such increases were also detected in osteoarthritic chondrocytes (OACs) in coculture with AMs, although the levels of MMPs and proinflammatory cytokines were already enhanced in OACs due to the natural disease process. The OACs cultured in the presence of nonactivated macrophages demonstrated a lower increase in levels of MMPs and proinflammatory cytokines, indicating that AMs may intensify the abnormal matrix degradation and cytokine secretion in OACs. In addition, AMs cocultured with OACs expressed significantly more IL-1b and VEGF-A compared to AMs alone, suggesting that OACs may also intensify abnormal activation in macrophages. Advantages of the proposed model: Despite the primary location of the macrophages in the knee joint within the synovial membrane, in the previously reported models of in vitro osteoarthritis, only the chondrocytes were cultured in a 3D microenvironment; the macrophages were cultured in 2D as a monolayer. The significance of the present model is to culture both chondrocytes and macrophages in a 3D environment. Moreover, the authors of the present report investigated the phenotypic changes in macrophages in coculture with chondrocytes; these cells have not been a focus of study in previous work dealing with osteoarthritis. Furthermore, the use of diseased rather than normal chondrocytes may enable the modeling of the later stages of osteoarthritis progression; this seems an appropriate model for testing potential therapeutic approaches of the disease. Next possible steps: Osteoarthritis progression involves many steps and interactions among different cell types and extracellular matrices. The work in the highlighted article, however, examined only the interaction between chondrocytes and macrophages for synovial inflammation. Moreover, models that recapitulate various stages in osteoarthritis are still needed. This work shows like other models before that is possible to obtain interesting answers even when using cell types from two different species (human chondrocytes vs. mouse macrophages). Future studies using primary human macrophages in the coculture system will be important to confirm the interaction between chondrocytes and macrophages described here. ________________________________ 3D in Publications Recent publications on 3D culture (please click to access the list on our web page https://nanohub.org/groups/3d3cfacility) Review<https://nanohub.org/groups/3d3cfacility/news#reviews> The research articles and reviews are arranged in the following categories: Scaffold free/Scaffold Organ/Tissue/Cell Others Spheroids<https://nanohub.org/groups/3d3cfacility/news#spheroids> Organoid<https://nanohub.org/groups/3d3cfacility/news#organoid> Scaffold<https://nanohub.org/groups/3d3cfacility/news#scaffold> Hydrogel<https://nanohub.org/groups/3d3cfacility/news#hydrogel> Matrix<https://nanohub.org/groups/3d3cfacility/news#matrix> Microfluidics<https://nanohub.org/groups/3d3cfacility/news#microfluidic> Microfabrication<https://nanohub.org/groups/3d3cfacility/news#microfabrication> Bone<https://nanohub.org/groups/3d3cfacility/news#bone> Bone Marrow<https://nanohub.org/groups/3d3cfacility/news#bonemarrow> Breast<https://nanohub.org/groups/3d3cfacility/news#breast> Colon<https://nanohub.org/groups/3d3cfacility/news#colon> Heart<https://nanohub.org/groups/3d3cfacility/news#heart> Liver<https://nanohub.org/groups/3d3cfacility/news#liver> Lung<https://nanohub.org/groups/3d3cfacility/news#lung> Muscle<https://nanohub.org/groups/3d3cfacility/news#muscle> Nerve<https://nanohub.org/groups/3d3cfacility/news#nerve> Prostate<https://nanohub.org/groups/3d3cfacility/news#prostate> Endothelial cells<https://nanohub.org/groups/3d3cfacility/news#endothelialcells> Fibroblast<https://nanohub.org/groups/3d3cfacility/news#fibroblast> Stem Cells<https://nanohub.org/groups/3d3cfacility/news#stemcells> Stromal Cells<https://nanohub.org/groups/3d3cfacility/news#stromalcells> Cancer/Tumor<https://nanohub.org/groups/3d3cfacility/news#cancer> Screening<https://nanohub.org/groups/3d3cfacility/news#screening> 3D bioprinting<https://nanohub.org/groups/3d3cfacility/news#3dbioprinting> Imaging<https://nanohub.org/groups/3d3cfacility/news#imaging> ________________________________ 3D in Meetings Keystone Symposia - Engineered Cells and Tissues as Platforms for Discovery and Therapy Date: 9th to12th March 2017 Location: Boston, Massachusetts, United States Website: https://www.keystonesymposia.org/17K1 Contact: Phone: 1 800-253-0685; Email: info(a)keystonesymposia.org<mailto:info@keystonesymposia.org> Organized by: Keystone Symposium Cell Culture World Congress USA 2017 Date: 23rd to 24th May 2017 Location: San Diego, California, United States Website: http://go.evvnt.com/68105-0 Contact person: Freya Smale This event allows research scientists engaged in upstream and downstream bioprocessing to discuss novel techniques and techniques and technologies.

Vibration Alert - Demolition of Housing North of the BNC
by Voorhis, Mark L. 08 Mar '17

08 Mar '17

Dear BNC User: I was notified today that the demolition of buildings in front (north of) the BNC will begin next Monday (3/13/17). This is part of the Innovation and South Street project. The demolition is expected to continue for approximately 3-4 weeks. The contractor will be working from 7:00 am until 5:30 pm Mon - Fri. It is possible that the BNC may experience vibration during this demolition process. Please be aware of this possibility and organize your work accordingly. Also, please notify me at mvoorhis(a)purdue.edu<mailto:mvoorhis@purdue.edu> if you experience any vibration issues in your research as a result of this demolition. Thank you in advance for your understanding during this Purdue University Physical Facilities (PUPF) project. From: Denecke, Jacob M Sent: Wednesday, March 08, 2017 1:37 PM To: Voorhis, Mark L. Subject: PVIL Demolition | Next Week Look Ahead Mark, Per our discussion, here is a look ahead for next week: We expect that heavy demo will commence on or after 3-13-17 at the far East end in front of Birck and will progress East to West toward Airport road. The buildings are masonry and concrete floor plates on bar joists and will come done easily. In the process of bringing them down it is possible that large sections of masonry wall or the floor plates will impact with the ground causing vibrations. The work hours will be 7 am to 5:30 pm M-F and the possibility of Saturday work as well. Within each building is a slab on grade and also a basement which will have to be demolished and could also cause some vibrations. The basement areas and utility trenches will have to be backfilled in lifts and vibratory compaction equipment will be used and will cause vibrations. We are currently erecting silt fence and other erosion control measures and installing tree protection fencing and other site prep, asbestos abatement and utility disconnections from the buildings. I'll send you additional updates as they become available. Please let me know if you would like additional person(s) CC'd on these updates. Please direct all PVIL demolition communication through me. As always, if you have any questions, please do not hesitate to contact me. Best Regards, Jacob Denecke, P.E.
