Lithium-rich layered oxide Li1.2Ni0.2Mn0.6O2 with a stable network flake structure has been synthesized through a facile resorcinol–formaldehyde (RF) organic carbon gel-assisted method. The as-prepared sample used as a cathode material in lithium ion batteries (LIBs) was characterized by X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), field-emission scanning electron mic...

Over the past decade, some groups have reported that nanofluids, which are liquids containing suspensions of nanoparticles, have substantially higher thermal conductivity than that of the base fluids. However, the reported high thermal conductivity sometimes cannot be reproduced. Theoretically, potential mechanisms leading to this enhancement are still under scrutiny. In this thesis, we present...

Abstract MXenes are atomically layered carbides and nitrides of transition metals that have potential for micro-devices applications in energy storage, conversion, transport. This emerging family materials is typically studied as nanosheets or ultra-thin films, which the internal defects mostly nanoscale flake-flake interface separation type. However, would require thicker exhibit very high den...

The preparation of two-dimensional transition metal dichalcogenides on an industrially relevant scale will rely heavily bottom-up methods such as chemical vapour deposition. In order to obtain sufficiently large quantities high-quality material, a knowledge-based optimization strategy for the synthesis process must be developed. A major problem that has not yet been considered is degradation ma...

Heavy mineral assemblages were studied in onshore sandy deposits from the 26 December 2004 tsunami on Kho Khao Island, southern Thailand. The most common minerals included tourmalines, zircon, muscovite, biotite, limonites and opaque minerals. An abundance of micas and depletion in tourmalines allowed us to distinguish the tsunami deposits from modern beach sediments and pre-tsunami soils. Majo...

Objective—To investigate possible neurotoxic eVects in groups of aluminium pot room and foundry workers, aluminium welders, and a small group of workers exposed to aluminium in the production of flake powder. Methods—Exposure to aluminium was evaluated with aluminium concentrations in blood and urine as well as a questionnaire. The groups exposed to aluminium were compared with a group of mild ...

The Zinc oxide nanoparticles were successfully synthesized using nitrate as the precursor and extract of Illicium verum was used reducing stabilizing agent. Synthesized particles in nano size characterizedby FT-IR, Ultraviolet-visible SEM & XRD techniques. formed confirmed zinc by UV- Visible, FT-IR spectroscopic data gave results regarding structure prepared nano-sized particles. According...
