Linker Encouraged Solid State Synthesis of MOF Derived Z-Scheme NiCoO/NiO/C toward Efficient Removal of Organic and Inorganic Pollutants from Water.

Here, we represent a solid-state route for the construction of MOF derived multifunctional Z-scheme NiCoO/NiO/C applied for the photocatalytic removal of methylene blue (dye) and tetracycline (drug) and the reduction of Cr(VI) (heavy metal). The developed solid-state method yielded a highly effective NiCoO/NiO/C catalyst by mechanically grinding independently produced Ni and Co-MOFs and subsequently pyrolyzing them. The use of different linkers in the Ni MOF (H-BTC linker) and Co-MOF (2-methylimidazole linker) proved to be effective in constructing the NiCoO/NiO/C composite, ensuring a nonaggregated distribution on a carbon framework.

La-Fe-O Perovskite Based Gas Sensors: Recent Advances and Future Challenges.

Interest in the importance of gas sensing devices has increased significantly due to their critical function in monitoring the environment and controlling pollution, resulting in an increased market demand. The present review explores perovskite La-Fe-O based gas sensors with a special focus on LaFeO and evaluates their sensitivity to a diverse range of practical target gases that need to be monitored. An analysis has been conducted to assess different routes not only of synthesizing LaFeO material but also of characterization with the targeted use for their gas sensing abilities.

Awareness, access, and communication: provider perspectives on early intervention services for children with sickle cell disease.

Purpose: This study aimed to identify determinants influencing the utilization of early intervention services among young children with sickle cell disease (SCD) based on perspectives from medical and early intervention providers.

Design And Methods: Early intervention and medical providers from the catchment area surrounding St. Jude Children's Research Hospital and Washington University were recruited (20 total providers).

Bismuth ferrite based acetone gas sensor: evaluation of graphene oxide loading.

We report a BiFeO/graphene oxide (BFO/GO) perovskite, synthesized using a CTAB-functionalized glycine combustion route, as a potential material for acetone gas sensing applications. The physicochemical properties of the developed perovskite were analysed using XRD, FE-SEM, TEM, HRTEM, EDAX and XPS. The gas sensing performance was analysed for various test gases, including ethanol, acetone, propanol, ammonia, nitric acid, hydrogen sulphide and trimethylamine at a concentration of 500 ppm.

Social participation of school-aged survivors of pediatric brain tumors: A daily diary report.

Background: Difficulties with social functioning are common among survivors of pediatric brain tumors. Social participation is an understudied measure of social functioning that is associated with emotional health across the lifespan. This paper uses a diary method to assess the social participation of survivors of pediatric brain tumors in middle childhood.
