Summary: Nanofluidic diode based on a covalent organic framework (COF) is studied, showing remarkable diode behavior in a hybrid-bilayer COF but not in its constituent single-layer COFs through molecular simulation. The rectification effect of ion current in the hybrid-bilayer COF is attributed to an asymmetric electrostatic potential across the COF nanopore. Furthermore, a synergistic effect of counterion is unraveled in the hybrid-bilayer COF, reducing the entry barrier and facilitating ion transport. The performance of the hybrid-bilayer COF as a nanofluidic diode is comprehensively investigated, demonstrating its feasibility and potentially stimulating the development of new nanofluidic platforms.

Summary: Cells coordinate their activities towards multicellular goals through efficient information processing mechanisms. Bioelectrical signals encode instructive rules at multiple scales, influencing transcription and morphogenesis. Biophysical models suggest that bi-stable and oscillatory bioelectrical memories can form pattern memories instructive for morphological outcomes. Multicellular aggregates exhibit spatio-temporal distributions of ions and activators correlated with electric potential patterns, forming dynamic subsystems with cells sharing the same bioelectrical state. Manipulating these subsystems allows for retrieval or rewriting of pattern memories, influencing morphology.

Summary: This paper compares two methods for analyzing the usage of earth pigments in historical paintings - one based on the correlation of Fe and Mn counts with the optical image of the painting, and the other based on Mn/Fe correlation plots. By identifying clusters within the correlation plots, the authors are able to determine the composition of different color areas and shed light on the different usage of these pigments in two paintings. The analysis of single-pixel spectra helps refine the interpretation of specific Mn/Fe correlation plots.

Summary: Electrochemical impedance spectroscopy (EIS) is a valuable tool in membrane science and technology that provides information on the structure and functionality of the membrane. By studying multipore asymmetric membranes with conical pores, it was found that the ionic conduction properties can be modulated by adjusting the electrical interaction between charges on the pore surface and the nanoconfined ionic solution. The membrane's electrical response was found to be influenced by the amplitude and frequency of the external voltage signal, the electrolyte type and concentration, and the solution pH.
