Maureen This update has been given to us by Robert Jones, Senior Superintendent of the construction site across the street from the Allen building. They will be closing the sidewalk on the west side of the building, the construction fence will moved to the poles right up to the poles of our building and they will demolish the sidewalk with jackhammers. We think this work will happen this Friday. You will have a couple of different options to get into the building. You can come through the doors facing the Packard building or through shipping and receiving on Via Ortega and if either of these potion doesn't work for you then your last option is to come through the side door of the Allen building that faces Serra. Expect delays so plan accordingly.

To mimic the best film, the goals of an image sensor have always been to achieve the most pixels, the smallest cost, the highest sensitivity, the largest signal-to-noise ratio, and etc. Despite that many of these goals compete against each other, image sensors today are amazing in terms of pixel count, sensitivity, low-cost, and read noise. During this sensor improvement, something else has been happening in imaging technology. Recently, a new approach of image creation called computational photography has emerged. In this approach, a picture is no longer taken but rather computed to improve image quality or produce pictures that could not have been taken by traditional cameras. Computing rather than taking a picture, however, is changing the requirements for image sensors. In this talk, I will present new image sensors with multi-bucket pixels that enable time-multiplexed exposure, an alternative imaging approach. This approach deals nicely with scene motion, and greatly improves high dynamic range imaging, structured light sensing, coded exposure, etc. Using some clever implant design, the new image sensors have successfully incorporated virtual phase charge-coupled device concept into a standard 4-transistor CMOS imager pixel, with small area overhead. Two image sensors with dual and quad in-pixel memories have been designed and fabricated. Pixel sizes of the two sensors represent state-of-the-art for this class of pixel. The technology allows both small cell size, and adjustable charge storage capacity. Using this sensor we have implemented and enhanced some computational photography applications and results agree with theoretical predictions. For computational photography researchers, the sensors will stimulate new software algorithms to be developed by providing a piece of hardware with new functionality.

Allen Auditorium (CIS-X 101) Lecture at 3:30PM Bioinspired Soft Materials to Direct Stem Cell Function and Tissue Regeneration *Kevin E. Healy* Jan Fandrianto Distinguished Professor in Engineering Departments of Materials Science and Engineering, and Bioengineering University of California at Berkeley Highly regulated signals in the stem cell microenvironment, such as growth factor presentation and concentration, matrix stiffness, and ligand adhesion density have been implicated in modulating stem cell proliferation and maturation. Therefore, it is desirable to have independent control over both the biochemical and mechanical cues presented to cells to analyze their relative and combined effects on stem cell function. Accordingly, we have developed synthetic hydrogels and biointerfaces to assess the effects of adhesion ligand presentation and material moduli spanning physiologically relevant ranges (10 to 10,000 Pa) on stem cell function. Employing these soft materials, we have demonstrated that the mechanical and biochemical properties of a stem cell microenvironment can be tuned to regulate the self-renewal and differentiation of different types of stem cells including human embryonic, neural, and mesenchymal stem cells. We have further modified these tunable biomimetic hydrogels with matrix metalloproteinase labile crosslinkers (e.g. MMP-2, 9 &13), to be used as an assistive microenvironment for transplantation of stem cells into diseased or damaged tissue such as the infracted myocardium. These biomimetic hydrogels provide a foundation for systematic development of ?pro-survival? microenvironments for cell transplantation and the potential improvement in the long-term results of regenerative therapies. Various examples from our work will be discussed during this presentation. ???MSE Undergraduate Summer Research Poster Symposium Science and Technology at the Nanoscale Friday, August 26, 2011 CIS-X Patio 4:30PM After the invited talk by Prof. Kevin Healy Sponsored by the Office of the Vice Provost for Undergraduate Education (VPUE) ** Pizza and drinks will be served** *#* *Student Name* *Advisor* *Project Name* 1 Dustin Barfield N.

Best, Yongliang From mtang at stanford.edu Tue Aug 23 16:01:54 2011 From: mtang at stanford.edu (Mary Tang) Date: Tue, 23 Aug 2011 16:01:54 -0700 Subject: OK to enter the lab, following evacuation Message-ID: <4E543162.10301@stanford.edu> Dear labmembers -- It is now OK to re-enter the lab. Many thanks to maintenance and facilities staff who stayed to check on their systems. This is what transpired. At 2:18 pm today, the fire alarms for the Allen/Annex building sounded and both buildings were evacuated. The cause was found to be an unstable toxic gas sensor in the occupied area of a lab in the Annex building. This particular sensor model is prone to false alarms, particularly when the weather is warm; as part of the upcoming renovation, these sensors will be replaced with more reliable ones. But we must all treat all alarms as real. When an alarm sounds, LEAVE THE LAB through the nearest exit. Continue out the building for fire alarm. Be aware that any labmember who does not evacuate promptly or re-enters before the area is cleared will have their lab privileges revoked. Always remember that your health and safety are more important than your experiment. That said, everyone who was inside the cleanroom at the time the alarm sounded evacuated beautifully (hooray!) Thankfully, this was not a true emergency -- but it is a reminder that we work in a building with many hazards and we should take them seriously.

B. Miller Date: Sept. 2, 2011 (Friday) Time: 1 PM (Refreshments served at 12:45 PM) Location: Paul Allen Auditorium (CISX-AUD) Abstract: One of the major challenges in the design of future integrated circuits is accommodating the increasing power consumption and bandwidth density of inter- and intra-chip communication links. Replacing wires with optical data links is a viable solution, provided device size and performance criteria are met. The quantum-confined Stark effect (QCSE) in Ge quantum wells (QWs) is a strong, efficient Si-based electro-optic mechanism for modulators operating in the communications band. Using the QCSE in Ge QWs, we have designed and demonstrated surface-normal asymmetric Fabry-Perot and microdisk resonator electroabsorption modulators. Leveraging advancements in SiGe epitaxy grown on silicon and metal contacting techniques, these devices are capable of high-speed, efficient modulation and compact form factors necessary for CMOS process integration. -- Elizabeth Edwards PhD Candidate Dept. of Electrical Engineering Stanford University Center for Nanoscale Science and Technology 348 Via Pueblo Mall, Stanford, CA 94305-4088 ehe at stanford.edu From dasgupta at stanford.edu Tue Aug 30 14:16:15 2011 From: dasgupta at stanford.edu (Neil Dasgupta) Date: Tue, 30 Aug 2011 14:16:15 -0700 (PDT) Subject: wet etching TiO2 Message-ID: <2079550784.932730.1314738975037.JavaMail.root@zm03.stanford.edu> Hi all, Does anybody have any experience wet etching TiO2 thin films?

I was surprised to find this.? 50:1 HF dip may be a little slow, but it is worth a try.? I would also try mixing 1 conc, HF to 9 H2O.? Or stronger still.??? What are you stopping on?? As always with wet etch, I recommend a hot plate re-bake, 4 or 5 min., 115 C within ~ 30 min of the wet etch.? If you stop and rinse for inspection, re-bake again before going back to the etch.? This helps a lot with resist lifting and undercut. TiO2 should plasma etch in an Al recipe, P5000 for semi-clean or PQuest for "golden" jim ________________________________ From: Neil Dasgupta To: labmembers Sent: Tuesday, August 30, 2011 2:16 PM Subject: wet etching TiO2 Hi all, Does anybody have any experience wet etching TiO2 thin films??
