Summary: A porous membrane-based diffusion scrubber coupled with a conductometric detector was developed as a flow-batch system for determining ammonium in turbid surface waters. The method utilized a gravity flow of DI water as absorbing liquid and manual sample introduction, resulting in a cost-effective device without the need for a conventional pump and an injection valve. The standard calibration graph showed a linear relationship in the range of 5-100 µmol/L with a relative standard deviation of less than 5%. The proposed method provided a detection limit of 5 µmol/L based on the lowest concentration in the calibration graph. The results obtained using the proposed method matched well with those using the batch-wise indophenol blue as a standard method. This analytical system offers a cost-effective setup and easy operation for ammonium determination in turbid surface water samples, eliminating the need for a filtering process and conventional glassware.

Summary: Enhanced electrocatalysts for formic acid oxidation reaction (FAOR) were prepared by constructing N-doped graphene oxide hybrid materials and loading electrodeposited Pd nanoparticles onto the prepared GO-xFBOPHY (x = wt%) support surfaces. The morphology of the prepared catalysts was characterized by TEM, and the phase and chemicals were determined by XRD and XPS, respectively. The electrocatalytic activity and stability of the catalysts were measured by CV and CA. The results showed that GO-2FBOPHY/Pd exhibited excellent catalytic performance for FAOR, with large active surface area (ECSA = 117.2 m(2)/g), high specific activity (8.53 mA cm(-2)), long-term stability (0.113 mA cm(-2) at potential 0.20 V), and fast electron transfer (charge-transfer resistance 1353 Omega). GO-xFBOPHY/Pd weakened the COads bond strength on Pd nanoparticles at a negative onset potential (0.60 V) compared to GO/Pd (0.66 V). These prepared catalysts could improve anodic oxidation and be used in direct formic acid fuel cells.

Summary: In this study, N-methyl mesoporphyrin IX (NMM) was utilized as a voltammetric probe for the electrochemical detection of G4s. The detection of NMM was achieved by cyclic voltammetry on a hanging mercury drop electrode (HMDE) with a limit of detection (LOD) of 40 nM. The reduction signal of NMM was found to be significantly higher when G4 oligodeoxynucleotides (G4 ODNs) were present compared to single- or double-stranded ODNs or unfolded ODNs capable of forming G4s. Gradual transition from unstructured single strand to G4, induced by increasing concentrations of the G4 stabilizing K+ ions, was detected for the first time using electrochemical methods. Circular dichroism spectroscopy provided support for the obtained results. This work expands on the utilization of electrochemical probes for DNA secondary structure recognition and offers a proof of principle for the development of novel electroanalytical methods for nucleic acid structure studies.
