Saline alkaline lakes that precipitate sodium carbonate evaporites are most common in volcanic terrains in semi‐arid environments. Processes that lead to trona precipitation are poorly understood compared to those in sulphate‐dominated and chloride‐dominated lake brines. Nasikie Engida (Little Magadi) in the southern Kenya Rift shows the initial st...
Laser trapping at an interface is a unique platform for aligning and assembling nanomaterials outside the focal spot. In our previous studies, Au nanoparticles form a dynamically evolved assembly outside the focus, leading to the formation of an antenna-like structure with their fluctuating swarms. Herein, we unravel the role of surface plasmon res...

Bread crumb firming is largely determined by the properties of gluten and starch, and the transformations they undergo during bread making and storage. Amylose (AM) and amylopectin (AP) functionality in fresh and stored bread was investigated with NMR relaxometry. Bread was prepared from flours containing normal and atypical starches, e.g., flour f...
Thermal treatment offers an alternative method for the separation of Al foil and cathode materials during spent lithium-ion batteries (LIBs) recycling. In this work, the pyrolysis behavior of cathode from spent LIBs was investigated using advanced thermogravimetric Fourier transformed infrared spectroscopy coupled with gas chromatography-mass spect...

Herein, a novel method for the adsorption of metal ions from sewage by NaP zeolite adsorbent synthesized from stage-treated coal fly ash (CFA) was proposed. The pre-treatment of CFA and grading extraction of silicon and aluminum were explored, and the effects of crystallization parameters and sodium salts on the yield and purity of NaP zeolites wer...

The preparation of solar grade silicon (Si) is popularly carried out in silica (SiO2) crucible containing porous alpha-Si3N4 coating, in which poorly wetting SiO(2 )film around alpha-Si3N4 particles act as barrier for Si infiltration. The present investigation studies the influence of oxygen (O) content in coating on wettability and infiltration fo...
