Summary: Two extremophilic biosorbents were used to successfully remove Cu(II), Ni(II), and Pb(II) from aqueous solutions. The biosorbents showed high affinity for these metal ions, with removal rates ranging from 73.6% to 100%, and the removal order was Pb(II) > Cu(II) > Ni(II). Both Langmuir and Freundlich models were suitable for describing the adsorption process, with the pseudo-second-order reaction model being more accurate than the pseudo-first-order model kinetically.

Summary: In this work, wafer-scale Ni and Cu heteroatomic thin films were synthesized without the use of any chemicals and used for non-enzymatic glucose sensing. The Cu-Ni thin films exhibited excellent electrocatalytic activity towards glucose oxidation, with a detection limit of 1.86 mu M. The Cu-Ni film showed significantly higher glucose oxidation activity compared to Cu and Ni electrodes, attributed to the synergistic effect of the bimetallic catalyst and high density of grain boundaries. Additionally, Cu-Ni electrodes showed excellent anti-interference characteristics. These results highlight the potential of Cu-Ni thin films for the development of non-enzymatic glucose biosensors.

Summary: A colorimetric probe based on gold nanoparticles (AuNPs), silver nanoparticles (AgNPs), and thymine (Thy) was developed for rapid and easy detection of copper (II) ions (Cu2+) in water samples. The probe showed excellent selectivity and sensitivity, allowing for Cu2+ determination within 15 minutes. It was capable of quantitative analysis using both smartphone application and UV-vis spectrophotometer.

Summary: It has been demonstrated that inexpensive and readily available N,N'-diaryldihydrophenazines can effectively replace Ir(III)- and Ru(II)-based photocatalysts in the dual photoredox/Ni(II)C-N coupling of aryl halides with a wide range of anilines, as shown by 32 examples. This efficient and operationally simple approach to diarylamines can be scaled up using a flow apparatus.

Summary: Cation exchange occurs during the synthesis of colloidal semiconductor heteronanoparticles, affecting their band gap and optoelectronic properties. The role of cation exchange during the growth of anisotropic dot-in-rod structures was studied. The dominant process in the initial stages of the shell-growth reaction was found to be cation exchange from ZnSe to CdSe.
