The study aimed to enhance the stability and efficiency of removing bivalent Pb(II) by encapsulating AlNi-layered double hydroxide (LDH) in chitosan and itaconic acid to create an adsorbent with chemically active sites. The resulting material, AlNi-LDH/CS, underwent thorough property analysis using XRD, FT-IR, XPS, EDX, N adsorption/desorption isotherm, and FESEM to find out what textural characteristics it has. Specifically, nitrogen adsorption/desorption isotherms were utilized to assess the textural properties of AlNi-LDH/CS.

Article Synopsis
  • The AcPase enzyme has a high specific activity of 31.32 U/mg with significant purification and a low yield of 3.15% compared to the Zn-dependent variant which has a lower specific activity of 14 U/mg and higher total recovery at 5.14%.
  • SDS-PAGE analysis shows a single band for each enzyme, with AcPase at 18 kDa and Zn-AcPase at 29 kDa, indicating their molecular weights.
  • AcPase shows broad substrate specificity, while Zn-AcPase shows preference for certain substrates, and various divalent metal ions enhance enzyme activity, while others inhibit it; competitive inhibitors have been identified for both enzyme types,

With the goal of developing a high-performance organic solar cell, nine molecules of A-D-A-D-A type are originated in the current investigation. The optoelectronic properties of all the proposed compounds are examined by employing the DFT approach and the B3LYP functional with a 6-31G (d, p) basis set. By substituting the terminal moieties of reference molecule with newly proposed acceptor groups, several optoelectronic and photovoltaic characteristics of OSCs have been studied, which are improved to a significant level when compared with reference molecule, i.

Modification of terminal acceptors of non-fullerene organic solar cell molecule with different terminal acceptors can help in screening of molecules to develop organic photovoltaic cells with improved performance. Thus, in this work, seven new molecules with an unfused core have been designed and thoroughly investigated. DFT/TD-DFT simulations were performed on studied molecules to explore the ground and excited state characteristics.

Flurbiprofen (FP) is one of the non-steroidal anti-inflammatory drugs (NSAIDs) commonly used to treat arthritic conditions. FP has two enantiomers: S-FP and R-FP. S-FP has potent anti-inflammatory effects, while R-FP has nearly no such effects.

New fluorescent 4-alkoxyphenyl-nitrothiophene compounds 4a-d bearing diverse alkoxyl tails are described. The synthetic strategy was simply accomplished by alkali-assisted alkylation of 4-(5-nitrothiophen-2-yl)phenol (3) with propyl, hexyl, nonyl, and/or dodecyl iodide. The molecular structures were determined using infrared (IR), H NMR, and mass spectroscopy.
