Abstract:
We present recent work on molecular strategies for photon downconversion and upconversion aimed at surpassing the detailed balance limit of solar cell efficiency.  For high-energy photons with energies above the semiconductor bandgap, singlet fission (SF)-a downconversion mechanism -helps mitigate thermalization losses. For low-energy photons below the semiconductor bandgap, triplet-triplet annihilation upconversion (TTA-UC) offers a complementary approach by enabling photon upconversion to reduce sub-bandgap losses.  Together, these strategies demonstrate how acene-based materials can address key loss mechanisms in conventional solar cells by managing both high- and low-energy photon losses. 

Abstract:
The development of new chemical methods for the next generation of nanoparticles with very high magnetic moment, fine tuning Au nanostructures and novel hybrid and multifunctional nanostructure is presented. Detailed mechanistic studies of their formation by sophisticated analysis of the nanostructure allows tuning of the physical properties at the nanoscale, which can be exploited for diagnosis and treatment of various diseases. The aim is to provide insight for future material design approaches and to identify the critical process parameters that can be manipulated to obtain suitable physical properties for the intended applications. 

Abstract:
This presentation will give an overview of scientific publishing, with a particular focus given to the Nanoscale journal family, introducing how these journals work together and how to select which journal is right for you. I will also describe the role of a scientific publisher, how to write your paper, what is needed for submission, peer-review, publishing ethics and open access, along with practical tips and tricks for preparing your manuscripts and navigating the publication process.
