In the past decade, nanoscale solid materials have become very important because of their
special properties, 1, 2 and the nanomaterials field has gained increasing attention from …

A facile, rapid and frugal approach was developed for the preparation of highly fluorescent
carbon quantum dots (CQDs) by pyrolysis of Finger millet ragi (Eleusine coracana) as a …

Green synthesis of carbon quantum dots (CQDs) from natural sources always remain an
attraction due to their excellent optical properties. In present work, highly fluorescent N, S co …

A facile, economical and effective green method was developed for synthesis of fluorescent
carbon dots (C-dots) from prawn shells. The results showed that these C-dots (with an …

A novel Schiff base ligand based nano-composite adsorbent (NCA) was prepared for the
detection and removal of copper (Cu (II)) ions in wastewater samples. Upon the addition of …

Herein, a novel MXene aerogel-CuO/carbon cloth (MXA-CuO/CC) electrochemical sensor
was constructed, and the synergistic adsorption of heavy metal ions by oxygen vacancies …

Abstract Copper ion (Cu 2+) and l-cysteine (l-Cys) detection is critically important since an
abnormal level of Cu 2+ or l-Cys is an indicator for many diseases. In this paper, we …

Metal ions are widely present in biological systems and participate in many critical
biochemical processes such as material transportation, energy conversion, information …

The phase-separation phenomenon of non-ionic surfactants occurring in aqueous solution
was used for the extraction of cadmium (II), lead (II), palladium (II) and silver (I). The …

The abnormal accumulation of copper ions (Cu 2+) is considered to be one of the
pathological factors of Alzheimer's disease (AD), but the internal relationship between Cu 2+ …
