_{Nucleation comprises the initial step of polymer crystallization, wherein the polymer melt stabilizes into ordered local structures, allowing for points from which polymer crystals can begin to grow. Nucleation quality can significantly impact the materials properties and processability of a polymer and is therefore of high importance to the materials science community. However, the collective understanding of polymer nucleation remains largely empirical.}

Methanotrophs produce methanobactin (Mbn), a copper-chelating peptide, when copper levels in the environment are low.^1,2 These methanotrophs utilize the copper-dependent enzyme methane monooxygenase to oxidize methane, which is the methanotrophs only carbon source.

Systems of chemical reactions are central to a wide range of technological and environmental questions, such as autoignition in combustion engines, heterogeneous catalysis, or formation of atmospheric aerosols. Understanding the details of these systems requires knowledge of not only the individual reaction steps but also the way these steps interact in the web of chemical transformations. 

One large roadblock to the development of commercially viable hydrogen fuel cells is the cost of the platinum group metal (PGM) oxygen reduction reaction (ORR) catalysts used in proton-exchange membrane fuel cells (PEMFCs). Unfortunately, similarly active catalysts, like Fe-N-C catalysts, have suffered from stability issues limiting their use. To better understand these stability issues and design better catalysts a number of degradation mechanisms have been proposed and experimentally tested including demetalation, autocatalysis, and more.

This study systematically examines the interactions of the tetrafluoroborate anion (BF₄^–) with up to four water molecules (BF₄^–(H₂O)_n=1,2,3,4).

There has been a growing interest in nitrogen-vacancy (NV) centers as high precision sensors in biology, chemistry, and physics. NV centers are naturally occurring defects in diamonds. They can detect nanoscale perturbations in local temperature, pressure, magnetic and electric fields. These quantum sensors perform optimally in ambient conditions, and their biocompatibility permits their use in vivo. The electronic states of the NV center can be controlled by optical pumping and measured by optical readout.
