Comparison of sulfuric and oxalic acid anodizing for preparation of thermal control coatings for spacecraft

The development of thermal control surfaces, which maintain stable solar absorptivity and infrared emissivity over long periods, is challenging due to severe conditions in low-Earth orbit (LEO). Some candidate coatings are second-surface silver-coated Teflon; second-surface, silvered optical solar reflectors made of glass or quartz; and anodized aluminum. Sulfuric acid anodized and oxalic acid anodized aluminum was evaluated under simulated LEO conditions. Oxalic acid anodizing shows promise of greater stability in LEO over long missions, such as the 30 years planned for the Space Station. However, sulfuric acid anodizing shows lower solar absorptivity

The top patient safety strategies that can be encouraged for adoption now

Progress in patient safety improvement has been hindered by a lack of high-quality research on error prevention, poor understanding of how context influences safety strategies, and insufficient information on how best to implement evidence-based safety strategies. The Agency for Healthcare Research and Quality funded a multi-institutional effort to address these challenges, which culminated in the release of the Making Health Care Safer II report. Detailing methodology that the report's authors used to systematically review the evidence on effectiveness, context, and implementation for 41 key safety strategies, this commentary presents 10 strategies considered ready for widespread implementation. These strategies—including checklists to prevent certain health care–associated infections and surgical complications, bundled interventions to reduce falls and pressure ulcers, and interventions to decrease medication errors and improve hand hygiene—are all considered to have strong evidence of effectiveness, minimal potential for adverse consequences, and be reasonably easy to implement. This commentary is part of a special patient safety supplement in the Annals of Internal Medicine
