Dr. Meng Qu, Senior Research Scientist at Schlumberger-Doll Research gave an introductory talk on how her team develops materials for oil and gas applications such as plug and abandonment (P&A) and drill bit.  She discussed how her team focuses on understanding the fundamental science of each material, and applies this knowledge to guide material design and development.


Dr. Hongjie Dai,
 Professor at Stanford University, first briefly reviewed his earlier work on carbon nanomaterials including carbon nanotubes and graphene nanoribbons, and fluorescence and fluorescence imaging in the previously unexplored 1000-1700 nmNIR-II window to benefit from greatly suppressed photon scattering at long wavelengths.Schlumberger_MaterialsScience_Lecture_0304

The second part of the talk focused on Dr. Dai’s work on advancing new types of electrocatalysts for renewable catalyst applications and the development of novel batteries. He talked about achieving record setting performance of electrocatalysts for water splitting including HER and OER. He showed how his lab has developed a novel Ni/NiO heterostructured hydrogen evolution reaction (HER) catalyst and a NiFe layered double hydroxide (NiFe LDH) oxygen evolution reaction (OER) catalyst to enable water splitting using a record low voltage of < 1.5 volt, making it possible to make an electrolyzer for hydrogen and oxygen gas generation running on a single AAA alkaline battery cell.

The talk was followed by a wine & cheese reception in the Photonics 9th floor atrium.

Assistant Professor Masha Kamenetska receives Patricia Mclellan Leavitt Research Fund

May 22nd, 2018 in Uncategorized

MASHAMasha Kamenetska, who holds joint academic appointments of Assistant Professor in Chemistry and Physics and is a member of Boston University’s Materials Science & Engineering Division, was recently awarded the Patricia Mclellan Leavitt Research Fund. This award is designed “to support research of one or more non-tenured junior faculty members, or graduate students, in chemistry or biology at the College of Arts and Sciences. Preference shall be given to female faculty who demonstrate a commitment to encouraging women to study science, or to female graduate students.”

Dr. Kamenetska will use these funds to support her research on the mechanism of gene regulation by nucleosomes. Nucleosomes are the basic unit of chromatin which package DNA inside the nucleus by winding 147 base-pairs around a core of eight histone proteins. They also regulate gene expression by impeding access to the genetic code by transcription machinery.  Using single molecule nanomanipulation and spectroscopy techniques, Dr. Kamenetska can probe molecular level structure of biological complexes such as nucleosomes to understand their function. With this award Dr. Kamenetska plans to fund graduate and undergraduate students to develop an optical tweezer instrument which measures force-dependent unwinding of individual nucleosome particles while tracking their position along the DNA.  In addition to supporting her lab at this critical early point in her career, this award will also benefit the undergraduate women who will work on this projects during the summer and fall.

Her unique research focus at the nexus of biology, chemistry and physics, and her commitment to encouraging women to participate in science, make her an ideal recipient for this junior faculty award. Congratulations Dr. Kamenetska!

2018 Lambert Lecture featured Dr. Eric Jacobsen of Harvard University

On April 30th, 2018 Dr. Eric Jacobsen, Sheldon Emery Professor of Chemistry at Harvard University, presented The 2018 Lambert Lecture, speaking on New Modes of Anion-Binding Catalysis.

His work is focused on low molecular weight, chiral organic molecules possessing distinct hydrogen-bond donor motifs, which have been shown to catalyze an array of C–C and C–heteroatom bond-forming reactions with high enantioselectivity and broad substrate scope. In particular, dual hydrogen bond donors such as ureas, thioureas, squaramides, and guanidinium ions have been studied in detail in the context of electrophile activation. These catalysts operate by either of two, fundamentally different modes of electrophile activation: 1) direct hydrogen bonding to a neutral electrophile, and 2) anion binding to generate chiral ion pair. We have applied the latter reactivity concept to several classes of cationic electrophiles that have presented long-standing challenges to asymmetric catalysis.

In this lecture, Professor Jacobsen described his detailed kinetic and mechanistic studies of catalytic anion-abstraction processes. He discussed how these investigations have revealed unexpected cooperative mechanisms, and new strategies for the design of highly efficient catalysts for a wide range of nucleophilic substitution reactions including enantioselective SN1 pathways and stereospecific glycosylation reactions.

The Lambert Lecture is supported by an endowment established by alumnus Benjamin Lambert, who earned his bachelor’s degree in chemistry at Boston University (CAS ’55). After graduating from law school, he went on to pursue a distinguished career as a patent attorney with such major pharmaceutical companies as Merck and Johnson & Johnson. Each year, the Lambert Lecture addresses different topics in chemistry, the field of Lambert’s undergraduate and graduate studies, and features some of the most distinguished and creative scientists working in the field today.
