Summary: We present a controllable and specific functionalisation approach for graphene field-effect transistors (GFETs) in order to detect small physiologically active molecules. The key step involves the noncovalent functionalisation of graphene with perylene bisimide (PBI) molecules directly on the growth substrate. This method allows for the homogeneous self-assembly of PBI molecules on graphene, followed by the immobilization of antibodies. The functionalised GFET devices showed excellent performance in terms of atomic force microscopy, Raman spectroscopy, and electrical measurements compared to conventional functionalisation methods. Specific sensing of small molecules such as methamphetamine and cortisol was achieved by monitoring the electrical changes of the functionalised GFET devices. The sensors were able to detect methamphetamine down to a concentration of 300 ng ml(-1).

Summary: A new class of 2D Ti3C2Tx (MXene) in different weight percentages were hybrid with TiO2 nanopowder to form TiO2/MXene nanohybrids, serving as electron transport layer (ETL) for carbon perovskite solar cells (PSC), through artist spray gun assisted (ASG) pyrolysis method. The influence of Ti3C2Tx on TiO2 in light absorption, charge separation and carrier dynamics was studied. The results showed that TiO2/MXene nanohybrids exhibited improved charge transfer and higher photocurrent, making them a promising ETL for enhancing the photo-conversion efficiency of carbon PSC. The TiO2-MXene (1 wt.%) nanohybrid ETL showed the highest PCE of 5.15% among the tested samples.

Summary: Pr3+-ion doped YF3, LaF3, and GdF3 nanoparticles were investigated for their physiochemical characteristics. The results showed that the crystal phase and crystallinity of the nanoparticles were influenced by the dopant ions and the host ion's ionic radius. YF3:Pr nanoparticles exhibited better emission and excitation transitions compared to GdF3:Pr and LaF3:Pr nanoparticles. The study suggests that YF3:Pr nanoparticles are a useful host matrix for the development of luminescent phosphor materials.
