The cover image shows the triphenylene molecule as a potential precursor to two‐dimensional graphite nanosheets in the interstellar medium. The barrier‐less, exoergic nature of the reaction reveals a versatile reaction mechanism that may drive molecular mass growth processes in cold environments in deep space. Read more »

Reversible Lattice-Oxygen Reactions in Batteries
Researchers quantified a strong, beneficial, and reversible (over hundreds of cycles) chemical reaction involving oxygen ions in the crystal lattice of battery electrode materials. The results open up new ways to explore how to pack more energy into batteries with electrodes made out of low-cost, common materials. Read more »
Conductive triethylene glycol monomethyl ether substituted polythiophenes with high stability in the doped state
Researchers synthesized and characterized two iodine-doped polymers with high conductivity and stability. The doping increases the transparency of thin films of the polymer, which are resistant to common organic solvents. All these properties indicate great potential for the polymers to be used in applications such as organic field effect transistors, organic photovoltaic devices, and sensors. Read more »
Biochemical and structural characterization of two variants of uncertain significance in the PMS2 gene
The lack of information as to whether a genetic mutation is pathogenic or benign causes ambiguity during clinical diagnosis and hinders appropriate treatment. Here, researchers use several techniques, including small‐angle x‐ray scattering, to help classify genetic variants associated with an increased predisposition to certain cancers. Read more »
Scientists Take a Deep Dive Into the Imperfect World of 2D Materials
Researchers combined a toolbox of techniques to home in on natural, nanoscale defects formed in the manufacture of monolayer WS2, measuring their electronic effects in detail not possible before. The latest result marks the first comprehensive study at the ALS involving nanoARPES, which researchers enlisted to probe the 2D samples with x-rays. Read more »
Plumbing the Depths of Interfaces and Finding Buried Treasure
Understanding the interfaces where solids and liquids meet is key to controlling a wide range of energy-relevant processes, from how batteries store energy to how metals corrode, and more. Now researchers have explored such interfaces and found what they describe as a treasure trove of unexpected results that expands our understanding of working interfaces and how to probe them.

How to Catch a Magnetic Monopole in the Act
A research team has created a nanoscale “playground” on a chip that simulates the formation of exotic magnetic particles called “monopoles.” The study could unlock the secrets to ever-smaller, more powerful memory devices, microelectronics, and next-generation hard drives that employ the power of magnetic spin to store data.

Winter 2019 Shutdown Recap
A two-month scheduled shutdown of the ALS is nearly complete. It allowed significant progress on two new beamlines under construction, QERLIN and Gemini, and also saw the completion of a long-term project to upgrade the storage ring’s radio frequency (rf) system. The facility should return to user operations as scheduled on February 28. Read more »
CVs Now Required for All On-Site Foreign Nationals
As of February 1, all on-site foreign nationals (non-US citizens) are required to provide their CV listing all science and technology activities to complete their registration. Read more »
February 2019 Message from the UEC
Fanny Rodolakis, the chair of the Users’ Executive Committee (UEC) for 2019, reports on the most recent UEC meeting and calls for speaker suggestions for this year’s User Meeting. Read more »
