Summary: Metal organic frameworks (MOFs) are ideal fillers for preparing mixed matrix membranes (MMMs) due to their molecular sieving property. Highly dispersed ZIF-8 nanoparticles with diameter of around 50 nm were prepared by coating isophthalic dihydrazide (IPD) molecular layer onto their surfaces. The modification of IPD greatly enhances the interfacial affinity between ZIF-8 and 6FDA-Durene polyimide (PI) in MMMs, resulting in improved gas permeation performance.

Summary: The City of Meycauayan in the Philippines is heavily industrialized and suffers from severe heavy metal pollution due to the discharge of toxic materials into the environment. This study analyzed soil and sediment samples from the Meycauayan River to identify the sources of heavy metal pollution, including Chromium, Mercury, Nickel, and Lead. The results revealed that the concentration of industrial activities downstream of the river caused severe pollution, particularly from tanneries, Pb-acid battery recycling, and gold smelting industries. The study emphasizes the urgent need to address heavy metal pollution in Meycauayan along with ongoing cleanup efforts by the local government.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
