Boosting the capacitive property of nickel cobalt aluminum layered double hydroxide in neutral electrolyte.

Layered double hydroxide (LDH) has shown great potential for energy storage due to their high theoretical specific capacitance, relatively low cost and eco-friendliness. LDH, however, always works in alkali aqueous electrolyte for supercapacitors, which brings serious environmental pollution. In this work, a reduced graphite oxide/Fe(CN)- nickel cobalt aluminum LDH (RGO/Fe(CN)-LDH) composite has been prepared via ion-exchange reaction using RGO/LDH as precursor.

Highly Selective Detection of Metronidazole by Self-Assembly via 0D/2D N-C QDs/g-CN Nanocomposites Through FRET Mechanism.

A 0D/2D (0-dimensional/2-dimensional) nanostructure was designed by self-assembly of N-C QDs and carboxylated g-CN nanosheets and used as a fluorescence resonance energy transfer (FRET) fluorescent sensor.

Boronic acid-modified polyhedral oligomeric silsesquioxanes on polydopamine-coated magnetized graphene oxide for selective and high-capacity extraction of the catecholamines epinephrine, dopamine and isoprenaline.

Amino-functionalized polyhedral oligomeric silsesquioxanes (POSS-8NH) were covalently bound to the surface of polydopamine-coated magnetized graphene oxide.

Ab initio Molecular Dynamics Simulation Study of Dissociation Electron Attachment to Lactic Acid and Isomer.

Dissociation processes of lactic acid and its isomer formed by low-energy dissociation electron attachment (DEA) in the gas phase are investigated by using ab initio molecular dynamics (MD) simulations. The ab initio MD simulations using an atom-centered density matrix propagation (ADMP) method are carried out to investigate the DEA dissociation process of lactic acid and its isomer. The analysis of the simulated dissociation trajectories of lactic acid and its isomer indicates that the C-C, C-H, and C-O bonds are cleaved within femtoseconds of the simulation time scale in the DEA dissociation process, and the difference in dissociation trajectory depends on the size of the three basis sets.
