The band structure of graphene, N-graphitic graphene, defect-graphene, and N-pyridinic graphene reveals the band opening features that influence adsorption interactions with K⁺ ions. The ease with which K⁺ ions interact on the graphene surface is facilitated by a larger bandgap energy. The bandgap energies of vacantcy-containing graphene and N-pyridine-doped graphene are larger, leading to greater K⁺ ion interactions. In the pyridine arrangement, the presence of N doping degrades graphene symmetry, changes Fermi levels and increases the bandgap. The greater the bandgap, the stronger the interaction of graphene with K⁺ ions. The interaction between K⁺ ions and N-pyridine-doped graphene, however, results in an energy that is too high in this approach.

Cyrene^® (2), a commercially available solvent, is obtained by hydrogenation of levoglucosenone (LGO, 1), itself the product of pyrolysis of acid-treated cellulose. iso-Cyrene (4) has now been prepared from iso-LGO (3) and shown to display certain complementary solvent properties.

This paper proposes a fluorescent aptasensor for detecting carbendazim (CBZ) based on the interaction among CBZ, CBZ-aptamer and Synergy Brands, SYBR Green I (SG-I). The results show the aptasensor has a linear range from 3.58 to 230 nM and a good limit of detection (LOD) of 3.58 nM.

The solubility of CO₂ in some of ionic liquids (ILs) was measured. CO₂ solubility in ILs with different alkyl chain lengths in the cation increased with increasing alkyl chain length. Also, CO₂ solubility increased with increasing anion basicity.

We developed a new amplified chemiluminescence sensing platform based on WS₂ nanosheet chemiluminescence resonance energy transfer (CRET) for light on detection of ochratoxin A (OTA). In this study, lambda exonuclease (λexo) was added to catalyse the degradation of phosphate-DNA in the dsDNA, which can then provide a stable supply of a form of the OTA aptamer-12-mer linker-DNAzyme that can easily bind to hemin and OTA.

Hydrogen-bonded supramolecules Tx-Ay were prepared by solution blending of triazine derivatives (Tx) and aromatic acids (Ay). ¹H NMR and FT-IR results showed that hydrogen-bonded supramolecules were formed in all triazine-aromatic acid groups except T3-A1. DSC and POM analysis indicated that T1-A4, T2-A4 and T4-A4 in A4 series showed columnar liquid crystal behavior in a certain temperature range, while T3-A4 was nematic liquid crystal; WAXS confirmed that T1-A1, T2-A1 and T1-A4 were room temperature columnar liquid crystals.
