“My time at [Pasadena City College] has opened doors to internships and clubs, giving me hands-on experience in electrical engineering,” says Ani Hakobyan, an electrical engineering student at Pasadena City College. “These opportunities have broadened my perspective on the field and helped me explore different career paths.” Ani is featured in a “Student Success” Q&A article produced by the Micro Nano Technology Education Center (MNT-EC), in which she discusses her experience at Pasadena City College, her academic and career goals, and how she balances the workload of classes with part-time work: https://lnkd.in/ecpb3Smt  

Register to attend a webinar on Friday (Nov. 1) on #nanometrology that involves #BigData, #ArtificialIntelligence (#AI), and modeling. Colin Ophus (Stanford University), Subramanian Sankaranarayanan (Center for Nanoscale Nanomaterials at Argonne National Laboratory), and Kamal Choudhary (National Institute of Standards and Technology (NIST)) will discuss measurement and analysis challenges in #nanotechnology that may be bottlenecked by computational challenges and large datasets. More details and registration information are available at: https://lnkd.in/gVnEdpuQ.

Congratulations to the winners of the “Art of Science” image contest, which was organized in celebration of #NationalNanoDay by the Northwestern University Atomic and Nanoscale Characterization Experimental Center (NUANCE Center & SHyNE Resource): https://lnkd.in/eppsk-8r . According to the NUANCE website, the contest commemorates and unveils the talented persons behind the instrument and the aesthetics emerging beyond the science.

Researchers from Penn State University, the Massachusetts Institute of Technology (MIT) (including the MIT Institute for Soldier Nanotechnologies), and North Carolina Agricultural and Technical State University have discovered a different version of the #HallEffect, called the nonreciprocal Hall effect, which, unlike the conventional Hall effect, does not require a #magnetic field. In this case, the Hall voltage is proportional to the square of the current instead of being proportional to the current. Also, unlike the conventional Hall effect, which is driven by a force induced by the magnetic field, the nonreciprocal Hall effect arises from flowing #electrons interacting with #platinum #nanoparticles. This discovery could lead to applications in the development of #quantum communication and harvesting of #energy via #RadioFrequencies. https://lnkd.in/ej-GCaJS (Work funded by the National Science Foundation (NSF) and the United States Department of Defense)

The next virtual session of the NanoEducators Quarterly Forum will be on Tuesday, Nov. 12. Berton Mahardja, Director of Global Education Initiatives at the SEMI Foundation and former school teacher, will introduce free resources for teachers that are available through the SEMI Foundation’s webpage, including a teacher-developed curriculum. These resources will help you introduce your students to #nanotechnology and #semiconductors! To attend, register here: https://lnkd.in/ewHVN2cB.

James Utama Surjadi of the Massachusetts Institute of Technology has won the #NanoInFocus image contest for his entry, Three-Dimensional Nanoarchitected Hexagonal Boron Nitride. 👏 https://lnkd.in/eDugP2h7 #NationalChemistryWeek

And the winners of the #NanoInFocus contest are … James Utama Surjadi (first place) for “Three-Dimensional Nanoarchitected Hexagonal Boron Nitride,” Caleb DeWitt (second place) for “Micro-Broccoli,” and Matthew Hershey (third place) for “Landscape of Nanospheres.” Check out these images at: https://lnkd.in/e5zJXbux. The NanoInFocus image contest was an opportunity for people to explore the beauty of the #nanoscale and learn the value of working at fundamental length scales. It was organized by the National Nanotechnology Coordination Office, on behalf of the National Nanotechnology Initiative, along with the National Science Foundation (NSF)-funded UC San Diego Materials Research Science and Engineering Center (UCSD MRSEC), and the American Chemical Society.

Researchers from the University of Virginia, the University of California, Berkeley, the University of Florida, the University of Tennessee, Knoxville, the University of Michigan, and the U.S. Department of Energy’s Sandia National Laboratories and Center for Integrated Nanotechnologies have developed an innovative technique to better determine the #nanoscale effects of #radiation on materials. Using advanced time-series #imaging techniques with a transmission #ElectronMicroscope, the team compiled more than 1,000 images capturing more than 250,000 #defects formed during ion #irradiation. The study revealed that defects in #copper and #gold exhibit different behaviors compared to those in #palladium. This distinction underscores the need for specialized analytical models to accurately study these materials under radiation. https://lnkd.in/ePwhsy2X (Work funded by the U.S. Department of Energy (DOE)) Kory Burns

A difficult-to-describe #nanoscale object called a #magnetic #skyrmion – which can be thought of as spinning circles of #magnetism – might one day yield new #microelectronic devices that can do more while consuming less power. Researchers from the Department of Energy's (DOE) Lawrence Berkeley Lab, Paul Scherrer Institute in Villigen, Switzerland, and Western Digital (San Jose, CA) have now made three-dimensional (3D) #Xray images of magnetic skyrmions. "Our results provide a foundation for nanoscale metrology for spintronics devices," said Peter Fischer, the scientist who led this study. The research was conducted in part at the Molecular Foundry, a DOE Office of Science user facility at Berkeley Lab. https://lnkd.in/gi_q564Y (Work funded by the U.S. Department of Energy (DOE)) David Raftrey

Researchers from New York University, the U.S. Department of Energy’s Brookhaven National Laboratory, the Korea Advanced Institute of Science and Technology, and the National Institute for Materials Science in Tsukuba, Japan, have pioneered a new technique to identify and characterize atomic-scale defects in a two-dimensional material (#2Dmaterial) called hexagonal #BoronNitride. The team was able to detect the presence of individual #carbon #atoms replacing #boron atoms in this material. "In this project, we essentially created a stethoscope for 2D materials," said Davood Shahrjerdi, one of the researchers involved in this study. "By analyzing the tiny and rhythmic fluctuations in electrical current, we can 'perceive' the behavior of single atomic defects." https://lnkd.in/e4VJPvt9 (Work funded by the National Science Foundation (NSF) and the U.S. Department of Energy (DOE)) Yong-Hoon Kim Zhujun Huang
