Mapping (Photo)Chemical Pathways using State-Resolved Imaging

Striking transformations in the chemical complexity of the Earth's atmosphere have led to a multitude of pathways to aerosol formation. Likewise, the search for more efficient fuels and engine designs has resulted in similar increases in the composition of combustible fuels. These changes present opportunities to the scientific community to develop a molecular-scale understanding of the available chemical pathways in both environments. The…


Combustion Chemistry of Cyclic Ether Radicals

Oxidation of hydrocarbons is comprised of a series of chemical reactions that are in constant competition based on the conditions of the reaction environment. Further understanding of these pathways and the implications of this competition is important to improving the efficiency of combustion systems used for transportation. To calculate the contribution of each reaction, quantification of the intermediates formed must be conducted. However,…


Singlet Fission Copolymer Design: An Approach toward building Third Generation Solar Cells

Singlet Fission (SF) is a process, in which a singlet excited state is converted into two triplet excited states within a molecular system [1] . From an application point of view, SF in the molecular semiconductor is known to generate triplet excitons that are energetically matched to the bandgap of silicon or perovskite [2] . When the triplet excitons generated by SF process are transferred to semiconductors, they create additional electron–…


Theoretical Analysis of Group 15 Periodic Trends in the Highly Strained PnC3H3 Molecule

The synthesis of highly strained molecules has garnered significant interest from the chemical community over the last few decades. The tetrahedral isomer of the C4H4 molecule (tetrahedrane) is a prototypical example of a strained molecule and remains elusive to experimental chemists despite its predicted theoretical kinetic stability[1]. Earlier this year Cummins and coworkers published a groundbreaking study in which they successfully isolated…


Nanocars: Transit for Nanoscale Construction

Controlled placement of molecules is a necessary step for the future of nanoscale synthetic methods. Although layer deposition methods provide a bottom-up process for the construction of microscopic structures, the lack of precision limits the minimum size of these designs. Nanocars, molecular machines designed for movement across solid-phase surfaces, offer a means of transporting molecules across a deposited substrate.1,2 The controlled…

Going Where Few Dare To: Investigating the Reactivity and Structure of Uranium Species Using Ion Trap Mass Spectrometry

Electrospray ionization and ion-trapping methods of mass spectrometry have significantly improved our ability to study gas-phase ion chemistry, and to determine the intrinsic structure and reactivity of metal ions and metal ion complexes. Ion traps with multi-dimensional (MSn) tandem mass spectrometry capabilities are versatile gas-phase "laboratories" within which ions can be manipulated and studied. Ion traps can also function as “sample…
