Compositionally complex doping of spinel oxides toward high-entropy oxides is expected to enhance their electrochemical performance substantially. We successfully prepared high-entropy compounds, the oxide (ZnMgCoCu)FeO (HEOFe), lithiated oxyfluoride Li(ZnMgCoCu)FeOF (LiHEOFeF), and lithiated oxychloride Li(ZnMgCoCu)FeOCl (LiHEOFeCl) with a spinel-based cubic structure by ball milling and subsequent heat treatment. The products exhibit particles with sizes from 50 to 200 nm with a homogeneous atomic distribution.

Although Kaposi sarcoma more commonly affects the cutaneous tissues, lymph nodes, and visceral organs, it can also be present in ocular and ocular adnexal tissues. We report a case of a 58-year-old Indo-Caribbean woman living with AIDS who presented with a large upper eyelid mass that was clinically diagnosed as Kaposi sarcoma.

- The study investigates how reallocating time among physical activity, sedentary behavior, and sleep affects obesity indicators like BMI and waist circumference across various age groups.
- Researchers analyzed data from 9,818 participants using isotemporal substitution models to understand the implications of these behavior changes.
- Results indicated that even small shifts of 10-30 minutes can significantly impact obesity, with reallocating moderate-to-vigorous physical activity (MVPA) to lighter activities or sedentary behavior having particularly detrimental effects.
