Biogenic Synthesis and Characterisation of Novel Potassium Nanoparticles by Flower Extract and Evaluation of Their Potential Antibacterial, Anti-biofilm and Antibiotic Development.

Scientific researches on the synthesis, characterisation, and biological activity of potassium nanoparticles (K NPs) are extremely rare. In our study, we successfully synthesised a novel form of K NPs using () flower extract as a reducing and capping agent. The formation of K NPs in new form (KO NPs) was confirmed by UV-vis and XRD spectra.

Preparation of novel BC nanostructure/Si photodetectors by laser ablation in liquid.

In this study, boron carbide (BC) nanoparticles (NPs) are synthesized by pulsed laser ablation of boron in ethanol at a laser fluence of 6.36 J cm pulse. The effect of numbers of laser pulses on the structural, optical, and electrical properties of BC NPs was studied.

Biosynthesis and antibacterial activity of manganese oxide nanoparticles prepared by green tea extract.

Amongst chemical and physical techniques, the biosynthesis method of metal nanoparticles has received the interest of many researchers owing to its environmental safety, simplicity and inexpensiveness. Manganese oxide nanoparticles (MnO NPs) were successfully synthesised using green tea extract as the reducing agent and characterised by UV-Vis spectroscopy, X-ray diffractometry and Fourier transform infrared spectroscopy. The shape and size of the MnO NPs were obtained by scanning electron microscopy.

Rapid Synthesis of Hexagonal-Shaped Zn(Al)O-MMO Nanorods for Dye-Sensitized Solar Cell Using Zn/Al-LDH as Precursor.

This study reports a simple new technique for the preparation of novel hexagonal-shaped mixed metal oxides (MMO) nanorods using Zn/Al-layered double hydroxide (LDH) as a precursor for dye-sensitized solar cell (DSSC) application. The effect of the Zn to Al molar ratio demonstrated a sound correlation between the obtained nanorods’ diameter and the fabricated DSSCs efficiency. Additionally, the optical behavior of the fabricated MMO film as well as the absorption enhancement due to the utilized dye are also demonstrated; a cut-off phenomenon at around 376 nm corresponds to the attained hexagonal nanorods.
