Gold nanoparticles synthesized in water droplets (Nano Lett, 2017, 17, 1336)

An entirely new method of nanoparticle chemical synthesis  based on liquid droplet irradiation with ultralow energy electrons. We have developed a source of electrons with energies close to thermal which leads to a number of important and unique benefits. The charged species, including the growing nanoparticles, are held in an ultrathin surface reaction zone which enables extremely rapid precursor reduction. (Nano Lett, 2017, 17, 1336).

Ultra-small Silicon-carbide Nanocrystals (Nanoscale 8, 2016, 17141)

Highly size-controllable synthesis of free-standing perfectly crystalline silicon carbide nanocrystals has been achieved for the first time through a plasma-based bottom-up process. This low-cost, scalable, ligand-free atmospheric pressure technique allows fabrication of ultra-small (down to 1.5 nm) nanocrystals with very low level of surface contamination, leading to fundamental insights into optical properties of the nanocrystals (Nanoscale 8, 2016, 17141).

Carbon nanotubes on Silicon nanocrystals (ACS Appl Mater Interfaces 8, 2016, 19012)

Carbon nanotube (CNT) growth has been demonstrated from partially oxidized silicon nanocrystals (Si NCs) that exhibit quantum confinement effects. We determine experimentally and explain with theoretical simulations that the Si NCs morphology together with a necessary shell oxide of ∼1 nm is vital to allow for the nonmetallic growth of CNTs. This contribution is of significant importance to the improvement of nonmetallic catalysts for CNT growth and the development of Si NC/CNT interfaces (ACS Applied Materials & Interfaces 8 (2016) 19012).

Doping drives surface chemistry in Silicon nanocrystals (ACS Appl. Mater. Interfaces 7, 2015, 28207)

Picture1

Doping of quantum confined nanocrystals offers unique opportunities to control the bandgap and the Fermi energy level. We reveal that surface chemistries induced on the nanocrystals strongly depend on the type of dopants and result in considerable diverse optoelectronic properties (e.g., photoluminescence quantum yield is enhanced more than 6 times for n-type SiNCs).

Atmospheric Pressure Plasmas for ‘‘Green’’ 3rd Generation PVs (Plasma Process. Polym. 13, 2016, 70)

Atmospheric pressure plasmas (APPs) have achieved great scientific and technological advances for a wide range of applications. The synthesis and treatment of materials by APPs have always attracted great attention due to potential economic benefits if compared to low-pressure plasma processes. Nonetheless, APPs present very distinctive features that suggest atmospheric pressure operation could bring other benefits for emerging new technologies. In particular,materials synthesized by APPs which are suitable candidates for third generation photovoltaics are reviewed here. (Plasma Process. Polym. 13, 2016, 70).
