SLAC Director Chi-Chang Kao Announces Kelly Gaffney as New SSRL Director
On Monday, August 18, 2014, SLAC Director Chi-Chang Kao announced:
“After a year-long international search for a new Director of the
Stanford Synchrotron Radiation Lightsource (SSRL), I am very pleased to
announce that Kelly Gaffney, a faculty member in the SLAC Photon Science
Department and a member of the Stanford-SLAC joint PULSE Institute, has agreed
to take on the role of SSRL Director. Kelly will officially start in his new
position this week.
A chemist by training, Kelly is one of the world’s leading experts in
using femtosecond x-ray pulses – ultrashort, intense pulses – to
study how chemical bonds are created and modified. Kelly focuses on how
material, chemical or biological changes occur on very fast time scales, but
the approach is one that can be used generally to study a wide range of
processes with facilities, such as SSRL and the Linac Coherent Light Source
(LCLS), also at SLAC. Kelly will use his expertise to expand research
programs at SSRL, strengthen the connection with Stanford, and develop a
long-term upgrade strategy for the facility. Kelly has the right skills for
this job and I look forward to working with him as we build on SSRL’s
successful past to define the facility’s next chapter.
I also want to thank Piero Pianetta, who has been serving as Acting Director
at SSRL, for the tremendous work he has done in leading the facility the last
year. Piero will return to his role as Deputy Director for SSRL and will
continue to be a guiding force for the facility’s people as well as a
great resource for Kelly as he steps into his new role.”

Lithium-Manganese Rich NMC Composite Cathodes with Cycling –

Responsible, eco-friendly and sustainable use of energy is one of the
biggest challenges in today’s world. Current rates of energy consumption
demand the development of efficient ways to store energy, for instance in safe
and durable rechargeable batteries. However, repeated charge cycles degrade
batteries over time, eventually leading to their failure. Researchers from the
University of Science and Technology of China, SSRL and Oak Ridge National
Laboratory have recently developed a new approach to visualize and quantify
changes in battery materials during electrochemical cycling – providing
crucial information for a better understanding of battery failure and potential
improvements of energy storage materials. Read more...

Microscopy of Micrometer-sized Germanium Particles in Battery Anodes –
Contacts: Johanna Nelson Weker and Michael Toney (SSRL)
Rechargeable lithium-ion batteries are widely used in a variety of
applications, ranging from consumer electronics to electric vehicles. Their
breadth of use makes the development of new, high-capacity battery materials
highly desirable. Yet, the progress of lithium-ion technology has been rather
slow over the past decades. One promising approach to enhancing the capacity of
lithium-ion batteries is to use silicon or germanium anodes that form alloys
with lithium during cycling. Unfortunately, these electrodes fail after a few
charge cycles for reasons that had not been fully understood. A recent
study has now revealed that fracturing of the anode material during
battery operation causes the anodes to malfunction. Read more...
SSRL Award Announced
Ying Diao Honored with 2014 Spicer Award for Her Work at
Excerpted from August 18, 2014 SLAC News Feature
Ying Diao, a SLAC/Stanford postdoctoral researcher who has brought key
innovations to a printing technique for flexible electronics, solar panels and
other uses, has been selected to receive this year's William
E. and Diane M. Spicer Young Investigator Award.
"I was surprised and honored to receive this award," said Diao,
who in 2011 joined research groups led by Stanford Professor Zhenan Bao and
SSRL's Stefan Mannsfeld as a member of SIMES, the Stanford Institute for
Materials and Energy Sciences. "It's humbling because I know how much
previous recipients have achieved to earn this award, and I admire many of
While she hadn't had much experience in x-ray science while pursuing her
PhD in chemical engineering at the Massachusetts Institute of Technology, she
welcomed the opportunity to engage in x-ray studies at SSRL. "I had
dreamed about using synchrotron facilities," she said. "I was very
much drawn to deciphering structures using x-rays." She quickly became a
regular participant in SSRL experiments.
Diao has been an author in 20 scientific publications since 2011, serving as
lead author for eight of those, including a Nature Materials publication detailing the
printing technique, dubbed FLUENCE,
that she developed. This technique combines multiple innovations to precisely
print semiconductors. One key innovation uses a blade embedded with tiny
pillars to "comb" ink that is spread on a heated layer. The ink
solution dries, crystallizing into a semiconductor material. Read more...
