Summary: One major challenge in membrane manufacturing is to reduce environmental impact by using biobased materials and limiting toxic solvents. Environmentally friendly chitosan/kaolin composite membranes were developed using phase separation induced by a pH gradient. Addition of PEG as a pore forming agent significantly modified the morphology and properties of the membranes, leading to increased porosity and formation of a finger-like structure with interconnected pores. The hydrophilicity of the membrane surface also increased, resulting in a threefold improvement in filtration properties.

Summary: This paper aims to demonstrate the four possible mapping functions for voltage or charge inputs and their corresponding time-domain or frequency-domain electrical charge outputs when a capacitive device is voltage-charged. Similarly, there are four more possible combinations when the device is current-charged. The dual relationship between each pair of functions is established using single or double Fourier transforms. All eight system functions align only if a constant time- and frequency-independent capacitance is assumed.

Summary: This study presents an innovative approach to improve the photovoltaic conversion characteristics and stability of perovskite solar cells through carbon electrode interface modification. By in-situ polymerization and carbonization on the surface of nano-graphite, a dendritic structure carbon electrode is formed, reducing the work function and aligning the energy levels with perovskite. This leads to improved charge and hole collection efficiency, resulting in increased photovoltaic conversion efficiency. Furthermore, the modified carbon electrode-based perovskite solar cells exhibit exceptional stability, maintaining high efficiency even without encapsulation.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
