While it is well established that atmospheric aerosols directly interact with solar radiation and indirectly alter cloud physical properties, there remains a sizeable uncertainty in aerosol influence on climate.¹ Challenges in constraining aerosol influence arise from their complexity at the individual particle-scale as well as the global-scale. At the particle-scale, aerosols may be internally mixed, being comprised of many different molecular species which alter the particle’s direct and indirect climate effects.

In the field of omics, while single omics techniques have proven adequate, it has been observed that using multiple omics techniques in conjunction yields more thorough and informative sample profiles. The rapid gas-phase structural separation of ion mobility-mass spectrometry is beneficial for high-throughput multi-omics.

As part of their ongoing commitment to outreach, the Newton lab from the UGA Department of Chemistry recently hosted Copper Callahan, a 2024 Governor's Honors semifinalist in science from Clarke Central High School in Athens. Dr. Newton had met Copper's high school teacher, Mr. Robert Pulliam, and discussed Dr. Newton's interest in providing outreach and mentorship opportunities for local students. Mr. Pulliam then suggested that the Newton lab could be helpful in aiding Copper in preparation for his upcoming Governor's Honors selection process.

Gold nanocrystals of controlled size and shape have tunable optical properties that enable new science.  Upon illumination with resonant light, these gold nanocrystals can not only scatter light but also generate plasmons (coherent oscillations of conduction band electrons).  These plasmons, in turn, can produce local electric fields and heat.  All these modalities mean that gold nanocrystals can serve as excellent contrast and imaging agents in aqueous matrices. In this talk I will describe the synthesis and shape control of these nano

Diazo compounds were first discovered by Peter Griess in 1858.¹ The diazo group has been widely used due to its diverse reactivity, including alkylation, carbene generation, nucleophilic addition, homologation, and ring expansion. 

Since approval by the FDA in 1989, erythropoietin (EPO) has been used extensively for the treatment of anemia – especially in those with chronic kidney disease, undergoing chemotherapy, or have acquired immune deficiency syndrome (AIDS).¹ EPO is a highly glycosylated glycoprotein containing three N-linked and one O-linked glycosylation sites.

Nanoparticles (NPs) are particles of approximately 1-100 nm in size and have properties not found in bulk samples of the same material. Different materials, such as polymers, metal oxides, silica, noble metals, and carbon, can be used to create nanoparticles, which can then carry a variety of bioactive substances for use in biomedical applications, such as proteins, nucleic acids, small molecules for chemotherapy, and diagnostics.
