6. Investigation of graphene oxide in diesel sootSwapna Mohanachandran Nair Sindhu, Sankararaman S, 2017, izvirni znanstveni članek Opis: Graphene has emerged as a potential material in various scientific disciplines, ranging from material science, engineering, and more
recently biomedicine. The paper describes the investigation of the presence of graphene and graphene oxide (GO) in the carbon soot of
internal combustion diesel engines. The UV-Visible, Fourier transform infrared (FTIR), X- ray diffraction (XRD), Photoluminescent
(PL) and Raman spectroscopic analysis of the sample provided a conclusive evidence of the formation of graphene and GO. The Field
Emission Scanning Electron Microscopy (FESEM) and Energy Dispersive Spectrum (EDX) of the sample show carbon nanoparticles
(CNPs) of size less than 50nm. The High -Resolution Transmission Electron Microscopy (HR-TEM) analysis confirmed the formation
of graphene sheets with carbon nanospheres attached to it. The study reveals the possible exploitation of the diesel soot for potential
applications in science and technology

7. Through-plane and in-plane thermal diffusivity determination of graphene nanoplatelets by photothermal beam deflection spectrometryHumberto Cabrera, Dorota Korte, Hanna Budasheva, Behnaz Abbasgholi N. Asbaghi, Stefano Bellucci, 2021, izvirni znanstveni članek Opis: In this work, in-plane and through-plane thermal diffusivities and conductivities of a freestanding
sheet of graphene nanoplatelets are determined using photothermal beam deflection spectrometry.
Two experimental methods were employed in order to observe the effect of load pressures
on the thermal diffusivity and conductivity of the materials. The in-plane thermal diffusivity was
determined by the use of a slope method supported by a new theoretical model, whereas the
through-plane thermal diffusivity was determined by a frequency scan method in which the obtained
data were processed with a specifically developed least-squares data processing algorithm.
On the basis of the determined values, the in-plane and through-plane thermal conductivities and
their dependences on the values of thermal diffusivity were found. The results show a significant
difference in the character of thermal parameter dependence between the two methods. In the case
of the in-plane configuration of the experimental setup, the thermal conductivity decreases with the
increase in thermal diffusivity, whereas with the through-plane variant, the thermal conductivity
increases with an increase in thermal diffusivity for the whole range of the loading pressure used.
This behavior is due to the dependence of heat propagation on changes introduced in the graphene
nano-platelets structure by compression.
