Ambient temperature solid-state reaction of Pb(OAc)2 with TabHPF6 afforded an intermediate product [Pb(Tab)2]2(PF6)4, which further reacted with 4,4'-bipy in the solid state to generate a unique 2D cationic coordination polymer [Pb(Tab)2(4,4'-bipy)](PF6)2 in quantitative yield. Both complexes possess a low dielectric constant and low dielectric loss in the high electric field frequency range.

Atmosphere-controlled high-voltage electrospray (AHES) was utilised to modify the structure of chitosan (CS) films. The applied voltage in the AHES process ranged from 60 to 100 kV, with variations in the O content of the propellant gas from 0 to 100 %. The number density of cations in the charging environment reached 600 × 10 cations/cm.

Ground-level ozone (O) can infiltrate indoor environments, severely impacting the environment and human health. Moisture-induced catalyst deactivation is a major challenge in catalytic ozone removal. MOF-template-derived heterojunctions supported by carbon materials can prevent chemisorption of water vapor at active sites.

Carbon dots (CDs) as a new class of photoluminescent zero-dimension carbon nanoparticles have attracted significant research interests owing to their extraordinary opto-electro-properties and biocompatibility. So far, almost all syntheses of CDs require either heat treatment or exertion of high energy fields. Herein, a scalable room-temperature vortex fluidic method is introduced to the CDs synthesis using the angled vortex fluidic device (VFD).

Dicarboxylic acids (DCAs), with their deliquescence and hygroscopic nature, can function as cloud condensation nuclei (CCN) and ice nuclei (IN), affecting rainfall patterns. DCA analysis can serve as organic molecular markers for anthropogenic and biogenic sources. Very few studies deal with the optimization of the protocol for qualitative and quantitative analysis of DCAs using gas chromatography-mass spectrometry (GC-MS).

A new approach for hydrogen isotope separation using an unsaturated organometallic complex was proposed. Adsorption measurements of [Mn(dppe)(CO)(N)](BArF) (Mn-dppe) (dppe = 1,2-bis(diphenylphosphino)ethane, BArF = B[CH(3,5-CF)]) using H and D revealed a significant difference in the adsorption enthalpy of H/D at much higher room temperatures than in previous studies, with D molecules being more strongly adsorbed on unsaturated metal sites. Mixed gas adsorption isotherms were calculated at each temperature using IAST, and it was predicted that D uptake was much larger than H uptake.
