- 2025| CEE (Chemical Engine...Nickel-based complexes are increasingly studied due to their promising roles in medicine, catalysis, and energy storage. This review offers an in-depth survey of recent progress in the synthesis of nickel complexes, with emphasis on methods involving both organic and inorganic ligands. The influence of ligand type on the stability, geometry, and electronic characteristics of these complexes is discussed in detail. Key analytical techniques, such as UV-Vis spectroscopy, FTIR, NMR, and X-ray diffraction, are highlighted for their importance in characterizing the structure and composition of nickel complexes. The review also examines the electrochemical properties of these compounds, focusing on their redox behavior and potential applications as catalysts in energy-related processes. Critical factors influencing the performance and reactivity of nickel complexes, including ligand environment, nickel oxidation state, and coordination geometry, are identified and analyzed. This article aims to provide valuable insights for researchers focusing on the design, characterization, and diverse applications of nickel-containing complexes in various scientific fields.

- Cobalt ferrite nanocomposite was synthesized and characterized by analytical techniques such as FESEM, EDS and XRD. The average crystallite size was found to be in the range of 10–12 nm with a cubic structure. Further, the nanocomposite was used for the detection of guanine (GU) and uric acid (UA) and found to be an efficient electrode modifier. The lower limit of detection for GU and UA was found to be 300 nM and 400 nM, respectively.

- This work reports the enantioresolution of (RS)-acebutolol (ACB) by a thin-layer chromatographic method involving colistin sulfate (CS) as chiral selector. For this purpose, glass plates of dimension (12 cm × 4 cm × 0.4 cm) were prepared and used in four different approaches. The chiral selector was used in four different approaches before or during the chromatographic processes. Out of several mobile phase systems tried, the mobile phase system MeCN–MeOH−H2O (5.5:2.5:1.0, V/V) was found to be successful for better resolution (RS = 2.2). To confirm the elution order, the chromatograms of (RS)-ACB were developed along with the pure enantiomer of ACB, i.e., (R)-ACB, and it was concluded that (R)-ACB eluted before (S) enantiomer. The detection limit for each enantiomer of ACB was found in the range 12−15 μg spot−1. The developed method can be applied for the enantioresolution of ACB and its analogs in dosage formulations.
