Congrats to Kwabena Bediako for Receiving a Heising-Simons Faculty Fellowship

The Heising-Simons Faculty Fellows Program catalyzes scientific discovery by investing in high-risk, high-reward research directions. The Program supports exceptional faculty working on topics in a diverse set of fields, including astronomy, physics, geology and geophysics, materials sciences (in both physics and engineering), and physical and materials chemistry. Program awards will focus on creative and novel approaches that promise to lead to important scientific breakthroughs contributing to a greater understanding of the universe and its components, from the molecular and atomic to the geological and planetary scales, among other areas. Awards also fund the development of new tools, techniques and measurements that help probe these physical phenomena in new ways.

The Heising-Simons Faculty Fellows awards will be made to two UC Berkeley faculty members each year. Each $1M faculty award will be distributed over a period of five years. All early- and mid-career UC Berkeley faculty regardless of their home department are eligible to apply.

Prof. Bediako’s project is “Manipulating Electron Transfer with Twisted Interfaces”.

Congrats to Kwabena Bediako for Receiving an NSF Career Award

Kwabena Bediako, campus assistant chemistry professor, was awarded the National Science Foundation, or NSF, CAREER award for his ongoing research and outreach proposal.

The CAREER award is a five-year grant open to assistant professors who are fairly early on in their careers, Bediako noted. This grant will help him and his team continue their work with structural distortions in atomically thin materials, as stated in the NSF award abstract.

“With the solids that we work with, the layers can slide over each other, so it turns out that you can also control how they are twisted to each other,” Bediako said. “Even this twisting effect — the angle that you twist them at can significantly transform how the material behaves.”

Electron-beam-induced dynamics of colloids at fluid interfaces

Abstract: Electron beams present a new platform for manipulating colloidal particles with localized nanoscale control. Leveraging the high spatial and temporal resolution of scanning electron microscopy, we investigate the driven response of dispersed silica particles pinned to the interface of an ionic liquid droplet. By tuning the beam voltage, we precisely adjust both the strength and polarity of the interaction, sweeping between repulsive and attractive regimes. With this improved control, we demonstrate the capability of directed particle transport for writing colloidal patterns at the droplet surface. We additionally use this platform to explore particle-particle interactions in dense monolayers of bidisperse size mixtures. We find that the interaction is inherently non-additive, as determined by the confined packing geometry. Adjusting the particle size ratio modulates this geometric non-additivity, providing a unique platform for systematically investigating its structural and dynamic consequences.

Speaker bio: Jonathan Raybin is a postdoctoral researcher at UC Berkeley working with Prof. Naomi Ginsberg. His research focuses on imaging the environmental response of soft materials outside of equilibrium, exploring a range of phenomena including fluctuations, transport, and phase transformations. He earned his PhD from the University of Chicago, studying block copolymer self-assembly under the supervision of Prof. Steven Sibener. Jonathan is the recipient of the Charles H. Viol Fellowship and an NRC Postdoctoral Fellowship.

Congrats to Jeremy Thurston for Receiving the Emil Wolf Outstanding Student Paper Award at Frontiers in Optics

Every year, the Frontiers in Optics conference holds the Emil Wolf Outstanding Student Paper Competition, acknowledging the excellence of students in presenting their work at the conference in both paper and poster form. This year, JILA graduate student Jeremy Thurston of the Murnane and Kapteyn research groups showcased his work in both a paper and presentation titled: “Bright Tunable Ultrafast Deep- and Vacuum-Ultraviolet Harmonic Combs,” which was awarded a prize by the judges for excellence in communication.

“I’m very honored to be selected by the FiO committee for this award and want to extend my congratulations to the many collaborators at JILA and KMLabs that contributed to this work,” stated Thurston about the award. Congratulations, Jeremy!

Congrats to Daniel Carlson for Receiving the Best Paper Award at Optica International Conference on Advanced Solid State Lasers

To honor students’ abilities for clear and effective communication in quantum physics, Optica offers a yearly “best paper” award at its International Conference on Advanced Solid State Lasers. This year, JILA graduate student Daniel Carlson was among the list of winners, with his presentation “Carbon K-Edge Soft X-Rays Driven by a 3 µm,1 kHz OPCPA Laser System” winning over the judges. Carlson, who is a researcher in JILA Fellows and University of Colorado Boulder professor Margaret Murnane and Henry Kapteyn, studies the creation of special X-rays using laser systems. Congratulations, Daniel!

Congrats to Drew Morrill for Receiving the Colorado Photonics Industry Association Poster Award

Drew Morrill’s poster, titled: “High-harmonic generation from a 3 μm wavelength OPCPA,” received an award from the Colorado Photonics Industry Association. The poster illustrates a method to generate soft X-rays using laser arrays. Congratulations, Drew!

MRS PREM Research Scholars Symposium

STROBE Director of Outreach and Broadening Participation, Dr. Sarah Schreiner, worked with the NSF and other PREM (NSF Partnership for Research and Education in Materials) faculty to develop and organize an MRS PREM Research Scholars Symposium at the 2023 MRS Spring Meeting in San Francisco. This symposium hosted over 100 undergraduate PREM Research Scholars from around the US for two days to participate in professional development and networking activities. Dr. Schreiner ran two workshops at the symposium on Networking at Conferences and Turning Your Science into a Story. The symposium ended with a poster session for all participants. The STROBE-PREM partnership, PEAQS, had 10 students from Fort Lewis College and Norfolk State University participating in the symposium.

CU Students Become Solar Scientists

An unusual research project at the University of Colorado turned more than a thousand undergrad students into instant solar scientists.

X-Ray/Raman Microfluidics Postdoctoral Fellow

Join our team at Lawrence Berkeley National Lab’s (LBNL) Chemical Sciences (CSD) Division as a Postdoctoral Scholar in developing X-Ray and vibrational spectroscopy techniques coupled to microfluidics. 

In this role, you will contribute to the development of a multimodal-in situ experimental platform for controlling the latent heat in phase change materials (PCMs) for thermal energy storage. You will leverage the potential of metal organic compounds with hydrogen and coordination bonds to modulate phase transition through inter and intramolecular interactions. By employing an advanced, multimodal characterization platform, that includes  in situ/multimodal Raman spectroscopy, X-ray scattering, ambient pressure X-ray photoelectron spectroscopy & synchrotron based Infrared Nano-spectroscopy at the Advanced Light Source, your work will provide molecular-level mechanistic insights into PCMs across various length and time scales.
