Summary: The CNG membrane, serving as a desolvation layer, effectively prevents water molecules from contacting the zinc anode, thereby delaying water-induced corrosion reactions and promoting redirected zinc deposition through deanionization shock. The flexible and toughened nature of the CNG membrane allows it to withstand strong forces and accommodate surface fluctuations of the zinc anode during plating/stripping processes, resulting in enhanced Coulombic efficiency and extended cycle life.

Summary: This study presents an innovative method for fabricating inkjet-printed tracks using Zn nanoparticle ink and low-temperature in situ chemical sintering of curing ink. Chemical curing allows for the use of flexible substrates that cannot withstand traditional high thermal budgets. A specific acid concentration in the curing ink is found to be crucial in determining the electrical properties of the printed Zn nanoparticles, resulting in highly conductive and mechanically flexible features. Additionally, a touch sensor circuit utilizing all-Zn printed conductive tracks is demonstrated.

Summary: Silver-bismuth double perovskites show promise as replacements for lead-based materials in photovoltaic devices. Dimensional reduction from 3D to 2D perovskite structure can improve their electronic properties, but also limits light absorption in the visible. Doping with iodide can achieve a bathochromic shift in absorption features of butylammonium-based silver-bismuth bromide monolayer double perovskite.

Summary: Thin, porous films of WO3 were synthesized using solution-based methods with polymeric structure-directing agents. The use of polyethylene glycol (PEG) led to fast reversible electrochromic switching and high coloration efficiency, while the use of a block copolymer (PIB50-b-PEO45) resulted in electrochromic performance similar to compact WO3. Films prepared in the presence of both PEG and PIB50-b-PEO45 showed the best characteristics with interconnected mesopores and improved electrochromic switching compared to compact or microporous WO3.

Summary: This study investigates the factors influencing the performance of polymer electrolyte membrane (PEM) electrolyzers, specifically the porous transport layer (PTL). By conducting numerical simulations and calculations, the researchers found that reducing porosity and fiber radii improved interfacial contact and electrical conductivity of the PTL, while decreasing the anisotropy parameters increased electrical conductivity in the through-plane direction. The design of PTLs should be differentiated based on the operating conditions, with lower porosity and fiber radii for nonstarvation conditions and higher porosity, lower anisotropy parameters, and smaller fiber radii for starvation conditions. Graded PTLs with customized porosity, fiber radius, and fiber orientation can enhance structural and transport properties.
