Practical methods to clean ITER's diagnostic mirrors and restore reflectivity will be critical to ITER's plasma operations. We describe a technique to assess the efficacy of mirror cleaning techniques and detect any damage to the mirror surface. The method combines microscopic imaging and reflectivity measurements in the red, green, and blue spectral regions and at selected wavelengths. The method has been applied to laser cleaning of single crystal molybdenum mirrors coated with either carbon or beryllium films 150-420 nm thick. It is suitable for hazardous materials such as beryllium as the mirrors remain sealed in a vacuum chamber.

I read with great interest the recent study by Omohwovo on wastewater management challenges in Africa, which has strong parallels with the Philippines' own struggles in this area. Like Africa, our country is experiencing rapid population growth and urbanization without the necessary infrastructure to support effective wastewater treatment. The Philippines is also facing poor wastewater management that has led to severe heath concerns for humans, animals, and ecosystem.

During the COVID-19 pandemic, synagogues faced closure, and many non-Orthodox communities transitioned their prayer services to online platforms. This presented a significant challenge for community leaders and rabbis who were faced with a profound community crisis. An innovative response emerged including new prayers and the adaptation of existing ones to better address the pandemic's unique realities, integrating aspects of health, divinity, community, and the environment.

CO mineralization, a pivotal technology in CO capture, storage, and utilization, promises to convert industrial waste into valuable industrial products. However, the intricate reaction mechanism and rate-limiting process remain inadequately elucidated. The suitable reaction conditions should be clarified when designing industrial produce.

Aviation is under tremendous pressure to mitigate its impacts on the climate, but the best response strategies are unknown today due to deep uncertainties. How low-emission fuels will scale to levels relevant for the industry, along with the best strategies for managing contrails and other non-CO effects, are unknowable today with unknown cost and disruption. A conventional risk-based approach that involves investment across a known set of options is unworkable; instead, we argue that an experimentalist approach is needed that addresses deep uncertainties head on.
