Description:About the Seminar: \n\nNanoparticles play a crucial role in adv
 ancing alternative and renewable energy technologies due to their unique p
 roperties and tunable structures. This presentation explores the nucleatio
 n\, growth\, and mechanistic pathways of both classic and selenium-contain
 ing nanoparticles (NPs)\, with a focus on formation kinetics\, stoichiomet
 ry\, and self-assembly. Key findings from well-established systems\, inclu
 ding BaSO4 and Pt\, will be discussed\, highlighting critical factors such
  as aggregation and rate constants. In more complex systems like Cu-P-Se\,
  particularly Cu3PSe4\, ex situ studies using XRD\, NMR\, and PDF beamline
  analysis reveal how selenium precursor chemistry influences nanoparticle 
 formation and stoichiometry. Challenges in synthesizing Se-containing NPs 
 and the complexities of their redox transitions will also be addressed. Th
 e broader implications for nanoparticle synthesis\, including retrosynthet
 ic approaches and future mechanistic studies using in situ techniques\, wi
 ll be outlined to advance the understanding of nanoparticle formation and 
 its application in energy-related fields. 4:00 pm
