AI Article Synopsis
- - A new Rh-Sb co-doped SrTiO photocatalyst (STO:Rh,Sb) was created using ball-milling, which improved its surface area and performance in breaking down acetaldehyde.
- - The activity of STO:Rh,Sb after 60 minutes of grinding was better than that of a similar photocatalyst (STO:Rh) without antimony, indicating antimony helps prevent recombination of charge carriers.
- - The STO:Rh,Sb photocatalyst maintained its effectiveness over three cycles, showcasing its durability and potential for use in environmental clean-up with visible light.
Article Abstract
A visible-light-responsive Rh-Sb co-doped SrTiO photocatalyst (STO:Rh,Sb) a solid-state reaction was successfully developed, following pulverization by using ball-milling. The prepared STO:Rh,Sb exhibited a large surface area and showed efficient photocatalytic degradation of acetaldehyde. The photocatalytic activity of STO:Rh,Sb ground for 60 min exceeded that of STO:Rh ground for 60 min (photocatalyst doped without antimony), indicating that doped antimony plays an important role in suppressing the Rh, which works as a recombination center, in STO:Rh,Sb. Furthermore, the photocatalytic performance of STO:Rh,Sb ground for 60 min was sustained over 3 cycles, confirming the chemical stability of the photocatalyst. Therefore, ground STO:Rh,Sb has the potential to be applied to environmental remediation under visible light irradiation.

January 2025
Background: Mission Controllers (MCs) are the main point of contact for space crews and are vital for successful human spaceflight. On a mission to Mars, there will be as long as 22-min one-way communication delays between the ground and the crew, causing major changes to current communication infrastructures.
Methods: This exploratory study assessed the impact of a 20-min one-way communication delay on MCs' task performance, workload, and stress levels under nominal and off-nominal conditions, conducted during a 21-d analog mission.

An 89-year-old male with a medical history of non-ischemic cardiomyopathy was initially admitted with acute hypoxic respiratory failure attributed to heart failure exacerbation. Aside from progressive dyspnea, a non-pruritic, non-painful rash and constitutional symptoms were reported. Initial work-up was remarkable for normocytic anemia, lymphopenia, mild hypercalcemia, and elevated inflammatory markers.
