8.3.2019 Measurements yielded precise atomic masses for nuclear reactions in the stars

Our body and the matter around us is composed of chemical elements mainly created in stars via nuclear reactions and complex nuclear reaction networks. To understand these processes, we need to know properties of participating nuclei, such as their masses. In her doctoral thesis in the field of nuclear physics at the University of Jyväskylä, M. Sc. Laetitia Canete has precisely measured the atomic masses of the radioactive isotope of six elements. The measurement data can be used to better model different astrophysical processes.

Dissertation: 22.2..2019 M.Sc. Oleg Kit (Faculty of Mathematics and Science, Physics)

Graphene is a material made of a single layer of carbon atoms. It is closely related to carbon nanotubes, which are used as reinforcing agents for durable products such as wind turbine parts, spaceship components, smart paints and sports equipment. According to a recent doctoral dissertation in physics and nanoscience, completed at the University of Jyväskylä, Finland, carbon nanotubes can be produced in a new way, by twisting ribbon-like graphene.

Dissertation: 1.3.2019 M.Sc. Luis Cort Barrada (Faculty of Mathematics and Science, The Department of Physics)
Mar 01, 2019 from 12:00 PM to 04:00 PM

One of the most used methods in condensed matter theory and quantum chemistry for the description of matter properties is Time-dependent density-functional theory (TDDFT), an alternative formalism to wave function methods which uses the time-dependent electronic density for the determination of any quantum average of an electronic system. In his dissertation M.Sc Luis Cort Barrada has tested Time-dependent density-functional theory with SCE density functionals which describe physics of strongly interacting electrons.

Dissertation: 18.12.2018: New hybrid material for in next generation flexible touch screen? (Shao)
Dec 18, 2018 from 12:00 PM to 04:00 PM

The latest dissertation of Physics gives important information to the nano-electronic and nano-biotechnology. The flexible transparent conductive thin films (TCFs) could use new complex of the environmental friendly hemisellulose with carbon nanotube. It could use in next generation flexible touch screen. In addition the found of functionality of chi-avidin could be used in biosensors.

Dissertation: 7.12.2018: Theoretical predictions help the dark matter hunt (Pirinen)
Dec 07, 2018 from 12:00 PM to 03:00 PM

A new PhD thesis in the University of Jyväskylä shows how utilizing tellurium as a detector material can help detect dark matter more effectively than currently used materials. The research also lays a foundation for differentiating between collisions caused by dark matter and neutrinos, the so-called ghost particles, in dark matter detectors using xenon.

1.3.2019 Time-dependent density-functional theory for strongly correlated electrons

One of the most used methods in condensed matter theory and quantum chemistry for the description of matter properties is Time-dependent density-functional theory (TDDFT), an alternative formalism to wave function methods which uses the time-dependent electronic density for the determination of any quantum average of an electronic system. In his dissertation M.Sc Luis Cort Barrada has tested Time-dependent density-functional theory with SCE density functionals which describe physics of strongly interacting electrons.
