Liquid Phase Exfoliation of Two-Dimensional Materials for Sensors and Photocatalysis-A Review.

Two-dimensional (2D) materials have rewritten many disciplines of modern science and technology, both through intensive fundamental research. In this review, we will provide a comprehensive summary of the properties, synthesis, characterization, and application of 2D materials (Graphene, Hexagonal boron nitride (h-BN) and transition dichalcogenide (TMD'S) in the context of electrochemistry and related scientific fields. 2D material nanosheets have been characterized by using different techniques such as X-ray diffraction, field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), UV-Visible Spectroscopy, FT-IR Spectroscopy and Atomic Force Microscopy.

Improving the process of research ethics review.

Background: Research Ethics Boards, or Institutional Review Boards, protect the safety and welfare of human research participants. These bodies are responsible for providing an independent evaluation of proposed research studies, ultimately ensuring that the research does not proceed unless standards and regulations are met.

Main Body: Concurrent with the growing volume of human participant research, the workload and responsibilities of Research Ethics Boards (REBs) have continued to increase.

Self-Assembly in Aqueous Oppositely Charged Gemini Surfactants: A Correlation between Morphology and Solubilization Efficacy.

Micellization behavior of oppositely charged gemini surfactants (anionic surfactant; phosphoric acid, P,P'-1,4-butanedieyl, P,P'-didodecylester, disodium salt (12-4-12A), and cationic surfactant; butanediyl-1,4, bis (N,N-hexadecyl ammonium) dibromide (16-4-16) or (D-isosorbate-1,4-diyl bis(N,N-dimethyl-N-hexadecylammonium acetoxy) dichloride (16-Isb-16)) has been studied (individually or of a gemini mixture) by conductivity and surface tension measurements. Critical micelle concentration (CMC) data show both synergistic (for 12-4-12A + 16-Isb-16) and antagonistic (for 12-4-12A + 16-4-16) interactions between the two components. Small angle neutron scattering (SANS) measurement shows formation of various aggregates, spherical (or ellipsoidal), rod-shaped, and vesicular, by changing the mole fraction (at fixed total surfactant concentration, 10 mM).
