A structurally modified quinazoline derivative (L) acts as highly selective chemosensor for Al(3+) ions in DMSO-H2O (1:9, v/v) over the other competitive metal ions. L shows a red shifted fluorescence after the addition of Al(3+) ions and later the further fluorescence enhancement is due to chelation enhanced fluorescence (CHEF) through inhibition of photoinduced electron transfer (PET). This probe (L) detects Al(3+) ions as low as 9nM in DMSO-H2O (1:9, v/v) at biological pH. The non-cytotoxic probe (L) can efficiently detect the intercellular distribution of Al(3+) ions in living cells under a fluorescence microscope to exhibit its sensible applications in the biological systems.

Toxic metal ion contamination poses a significant environmental challenge, severely impacting plant growth, development, and reproduction. To cope with metal-induced stress, plants have evolved diverse molecular and physiological mechanisms. Among these, the xyloglucan endotransglucosylase/hydrolase (XTH) gene family, which encodes enzymes responsible for cell wall remodeling, plays a crucial role in enhancing plant resilience to metal ion stress.

Excessive aluminum ions (Al) contaminate environmental water bodies, and once they remain in the human body, they will pose a threat to human health. In this paper, a benzothiazole-based fluorescent sensor named BHMH for detecting Al was successfully synthesized and comprehensively characterized. It exhibited remarkable selectivity and sensitivity, manifested by a substantial fluorescence augmentation and a discernible color alteration in the presence of Al.

Aluminum (Al)-ion batteries have gained popularity because of their improved energy density, increased safety, eco-friendliness, abundant Al resources, and extremely attractive three-electron redox, making Al-ion batteries an appealing candidate. However, the progress in Al-ion batteries has been hindered by the unavailability of potential cathode materials that could reversibly host Al ions. In this work, we investigated VSe, a 2D material with a graphene-like layered structure, as a potential cathode for aqueous aluminum-ion batteries.

Xanthan gum (XG) has performed far better than other polysaccharides for industrial purposes, e.g., food, pharmaceutical, and cosmetic applications, due to its outstanding thickening effect, pseudoplastic rheological properties, and non-toxicity.

A novel fluorescent and colorimetric probe (L3), based on 2,6-pyridinedicarbohydrazide, was rationally designed and synthesized for the highly selective and reversible detection of Cu²⁺ ions. The structural and optical properties of the probe were comprehensively characterized by FT-IR, ¹H NMR, UV-Vis spectroscopy, fluorescence analysis, ESI⁺-MS, and elemental analysis. The probe L3 displayed a high selectivity, high sensitivity and quick response to Cu ions in the presence of other competing cations including Ba, K, Pb, Hg, Al, Zn, Fe, Tl, Mg, Ni, Nd, Fe, Ag, Ca, Cs, Co, Cd, Sr, and Mn ions).
