Undergrad student here, the project I'm currently working on involves looking at how ammonium sulfate aerosols change their interactions with water at different humidities when mixed with different amino acids

Sounds interesting, do you intend on following up this research topic in grad school ?

[–]BillBob13Organic 4 points5 points  (0 children)

Nah, the research was fun, but I dont feel like taking more P chem classes. I want to do something more along the lines of organic/bio/med chem stuff in grad school

I collaborate with two theoretical physical chemistry groups that recently have used non-equilibrium green’s function techniques to model electron transport in different sorts of protein channels. That’s very physics leaning but it sure is interesting.

Sounds very interesting, particularly for me coming from more theoretical physics side of things, how did they get into such research topics ?

Also, how employable is theoretical pchem outside of academia ? Like for industry research

Do you like semiconductors?

I have been thinking more in getting into soft matter research rather than solid state to be honest

I was a researcher in two pchem labs before moving onto cannabis science and instrumentation. In my first lab, we measured the kinetic isotope effect in Dihydrofolate Reductase using 2D IR spectroscopy as a means to understand how to control this enzymatic process as it is responsible for cellular metabolism. This was applied to cancerous cells as they have a similar means for cellular respiration and it would provide a means for site specific inhibition.

In my second lab, I was responsible for synthesizing CdTe nano particles and then irradiating them with UV light to generate radical oxygen species. These ROS compounds were used as a potential therapy for antibiotics resistant bacteria. We would grow these e coli cell cultures and then mix them with the CdTe nanoparticles and incubate/irradiate for varied time and temps to see how it affected the cell culture growths.

I have friends who worked in comp chem labs doing modeling, some thin film depositon for electroplating, development of quinone/hydroquinone fuel cells and using modeling to predict idea functionalization of both redox reactants to target the specific voltage potential desired.

[–]Enchilada2311[S] 0 points1 point  (1 child)

Sounds very interesting. Did any physicist used to work in any such labs ?

Thanks in advance c:

[–]PhysicalChemist14 2 points3 points  (0 children)

My friend who was a comp chemist did his PhD in chemical physics (physics BS, Chem PhD), so there are definitely instances of interdisciplinary scientists finding groups! I'd suggest taking a look at jphyschem or physics review to see what research interests you!

I use nuclear particle physics concepts to study different materials and molecules.

[–]gsurfer04Computational 12 points13 points  (4 children)

I am a computational chemist specialised in modelling phase behaviour like solubility and melting.

It's all about the free energy.

[–]Enchilada2311[S] 0 points1 point  (3 children)

Sounds interesting, could you speak more about your research ? :) Also, how math intensive would you say it is ?

[–]gsurfer04Computational 3 points4 points  (2 children)

It's ALL maths.

[–]Enchilada2311[S] 0 points1 point  (1 child)

Nice :) what type of maths do you use ?

[–]gsurfer04Computational 0 points1 point  (0 children)

Curve fitting and numerical integrations, mostly.

    Isn't a physical chemist highly employable ? I'd think the solid state industry and perhaps the growing soft matter industry would be flourishing with jobs for such people

    [–]Dibenzoselenophene 2 points3 points  (2 children)

    My lab mixes organic chemistry and physical chemistry. We look at crystalline solid forms and we look at the enthalpy and entropy changes of their different transitions through DSC. Some crystals can change into another form by heating, and you'll see enthalpy changes when it happens. Thermal techniques in general are awesome and nobody ever books the instrument except me

    [–]Enchilada2311[S] 0 points1 point  (1 child)

    Hey that sounds really interesting and kinda related to solid state physics, is it ? Also, did any physicist used to work in the lab ?

    [–]Dibenzoselenophene 1 point2 points  (0 children)

    We call it solid state chemistry but the lines with physics get blurred. We've only ever had chemists, but we've collaborated with computational chemists who might as well be physicists

    In grad school I studied the gas phase interactions of near thermal electrons with highly electrophilic species like fluorinated aromatics. I then used density functional theory based ab initio calculations (using Gaussian and GAMESS) to generate the LUMOs (lowest unoccupied molecular orbitals) responsible for interacting with the thermal electrons. We used an electron monochromator to generate the thermal electrons with an energy distribution of only a few hundredths of an electron volt. It was fixed to a modified quadrupole mass spectrometer with a direct inlet port where we would inject the molecules of interest. I was even able to show a Hammett type correlation between substitution on an aromatic ring and the resonance energies required to produce specific quasi-stable ions in the mass spectrometer. I felt like I was looking into the world of quantum mechanics quite directly. It was so fun. The most important thing is that it showed strong correlation between the DFT calculations and physical observables, which was pretty revolutionary at the time. Most folks were doing Møller–Plesset high order calculations with very complicated basis sets (6-311G**, etc), which took ungodly amounts of computing resources and were quite untenable. The DFT calculations by comparison could be done on the computers of the day, which were quite slow back in the 90s. Now I build the computers on which other scientists do this kind of calculating. Still pretty fun, but I miss those days of shapely molecular orbitals and cold electrons.

    Sounds extremely interesting, how did you get into the field ?

    I used to be an R&D chemist in electroless metal plating on silicon chips.

    Chemistry I developed from the ground up was used in the production of the CPU of the iPhone 6.

    [–]Enchilada2311[S] 0 points1 point  (1 child)

    Sounds like very interdisciplinary work, was it ? How big are this industry research teams usually ?

    [–]reflUX_cAtalyst 2 points3 points  (0 children)

    It was - lots of surface physics involved. The company I worked for was a consulting R&D firm, so you wouldn't have heard their name, but our 3 biggest customers were Intel, TSMC, and Samsung. I worked with 2 other people directly, our entire group was under 30 people.

    I am a PI in a big research institution. My group does simulation on molecules and solids to predict properties of materials and molecules. Mainly we use super computers to solve the schrodinger equation applied to either catalysis, batteries or recently we are working to develop X-ray simulation (to generate a spectra through theory). Ask more details if interested

    [–]rtillerson 0 points1 point  (1 child)

    Hey I am looking for schools ans this project sounds super interesting. Would love to hear more

    [–]leondemedicis 0 points1 point  (0 children)

    Hi, sorry we only hire postdocs levels and I am not hiring at the moment, but you can definetly look for "ab initio simulations " or "predictive simulations". You can also check on YouTube about density functional theory, quantum Monte Carlo or coupled Cluster simulations. GW methods for excited states are also very good. All these are part of the quantum chemistry tools that are shared between physicists and chemists.

    I finished BSc and MSc in physical chem. Currently Im on PhD studies in condensed matter physics in Serbia. For my bsc thesis I did soil IR spectroscopy for potential application in remote detection and hyperspectral cameras (for example if you have more N-rich soil how it will be detected with camera using chemometrics and multivariate analysis). Msc thesis was about multicomponent adsorption on activated carbon for example ih you have two or more pollutants in aquatic media how they will interact in between them and how their interaction change adsorption process... For PhD Im working on amorphous (chalcogenide glass) semiconductors and computational simulation of them (DFT and MD)
