Article Synopsis
- - The study introduces a technique called four-dimensional (4D) scanning transmission electron microscopy (STEM) to analyze nanoscale ordering in disordered organic semiconducting polymers, which is critical for understanding their properties.
- - By utilizing advanced nanodiffraction patterns and reconstruction methods, researchers were able to visualize the ordered domains in materials like P3HT and IDTBT, allowing for detailed measurement of molecular stacking and orientation.
- - The results revealed a clear correlation between the type and size of molecular ordering in the samples, with various analyses providing insights into the molecular structures and changes that occur when fullerenes are added to P3HT.
Conductive and transparent coatings consisting of silver nanowires (AgNWs) are promising candidates for emerging flexible electronics applications. Coatings of aligned AgNWs offer unusual electronic and optical anisotropies, with potential for use in micro-circuits, antennas, and polarization sensors. Here we explore a microfluidics setup and flow-induced alignment mechanisms to create centimeter-scale highly conductive coatings of aligned AgNWs with order parameters reaching 0.

In this study, a green synthesis method was performed to prepare nanohybrids of GO and nZVI to provide an adsorbent with high adsorption efficiency that can be removed from aqueous solution easily by magnetic separation. GO-nZVI nanohybrids were synthesized by using biocompatible cross linkers named 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide (EDC) and -hydroxysuccinimide (NHS).
