Summary: In this study, highly ordered nanoporous carbon decorated with CaF2 nanoclusters are synthesized using dairy milk as a carbon and calcium source through nano-hard templating approach. The materials exhibit high specific surface area and bimodal porous structures, with stable electrode performance and high capacitance of 182 F g(-1) at 0.5 A g(-1) with nearly 100% retention rate after 5000 cycles due to the strong intimate coupling generated by the CaF2 nanoclusters within the wall structure. The electrode performance of milk derived carbon samples is superior to other carbon materials such as activated carbon, multiwalled carbon nanotubes, and mesoporous carbons without CaF2.

Summary: The assembly pattern of micelles plays a crucial role in determining the architectures of carbon materials prepared via soft-templating method. In this study, a kinetics-controlled strategy is developed to fabricate ordered mesoporous carbon (OMC) single crystals from liquefied wood by regulating the polymerization rate of carbon precursors using melamine. The addition of melamine slows down the reaction kinetics, allowing composite micelles to orderly aggregate and form OMC single crystals with high specific surface areas, uniform mesopore size, and ordered Im3m mesostructure. These OMC single crystals show excellent catalytic performance for the reduction of 4-nitrophenol when coupled with Ag nanoparticles.

Summary: This study investigates the performance of individual ions in salt solutions and the impact of ionic hydration on hydrogen bonding network distortion, surface stress, and solution viscosity. The findings reveal that ions occupy the interstitial space of water eccentrically to form hydration cells, and the polarization of ions affects the length and stiffness of H-O bonds. Furthermore, the screening effect of hydrating water dipoles limits the size of cation hydration cells, while inter-anion repulsion reduces the hydration volume. The polarization of cations and anions contributes to the linear and nonlinear components of viscosity and surface stress.

Summary: In this paper, a graphdiyne (GDY)-modified glassy carbon electrode was prepared and used for the sensitive and simultaneous detection of Zn2+, Cd2+ and Hg2+ heavy metal ions. The GDY-modified electrode provided a larger surface area and more active sites for the absorption of metal ions. By codeposition with Bi3+, the heavy metal ions were pre-concentrated on the GDY-modified electrode surface, resulting in high sensitivity and selectivity during stripping analysis. The detection ranges and limits for Zn2+, Cd2+ and Hg2+ were determined using differential pulse anodic stripping voltammetry.

Summary: A novel colorimetric aptasensor was developed to detect ochratoxin A (OTA) by utilizing charge effect-assisted silver enhancement. Gold nanoparticles (AuNPs) were used as carriers of aptamers tagged with a positively charged tetramethylrhodamine (TAMRA), which catalyzed silver reduction and deposition. The TAMRA attracted and retained the silver lactate around the AuNPs due to the attraction between positive and negative charges, increasing the chance of AuNP-catalyzed silver reduction. The charge effect-assisted silver enhancement was confirmed by tagging aptamers of different base pair lengths with TAMRA. The as-prepared OTA aptasensor exhibited a working range of 1 x 10(2)-1 x 10(6) pg mL(-1) and a detection limit of 28.18 pg mL(-1). It was successfully applied to determine OTA in actual samples with satisfactory results.

Summary: Black phosphorene quantum dots (BPQDs) with proven morphologies by TEM results were prepared using ultrasonic-assisted liquid-phase exfoliation and centrifugation. A novel electrochemical enzyme sensor was then developed by co-modification of BPQDs with horseradish peroxidase (HRP) on a carbon ionic liquid electrode (CILE). The presence of BPQDs accelerated the electron transfer rate between HRP and the electrode surface, resulting in well-shaped voltammetric peaks and a fast channel for direct electron transfer.
