Unlocking Micro-Origami Energy Storage.

Transforming thin films into high-order stacks has proven effective for robust energy storage in macroscopic configurations like cylindrical, prismatic, and pouch cells. However, the lack of tools at the submillimeter scales has hindered the creation of similar high-order stacks for micro- and nanoscale energy storage devices, a critical step toward autonomous intelligent microsystems. This Spotlight on Applications article presents recent advancements in micro-origami technology, focusing on shaping nano/micrometer-thick films into three-dimensional architectures to achieve folded or rolled structures for microscale energy storage devices.

Synergy and competition during the anaerobic degradation of N-acetylglucosamine in a methane-emitting, subarctic, pH-neutral fen.

Peatlands are invaluable but threatened ecosystems that store huge amounts of organic carbon globally and emit the greenhouse gasses carbon dioxide (CO) and methane (CH). Trophic interactions of microbial groups essential for methanogenesis are poorly understood in such systems, despite their importance. Thus, the present study aimed at unraveling trophic interactions between fermenters and methanogens in a nitrogen-limited, subarctic, pH-neutral fen.

A bright future for micro-LED displays.

The development of GaN-based Micro-LED arrays achieving brightnesses exceeding 10 nits and high-density micro-displays with up to 1080×780 pixels marks a true breakthrough in the field. This breakthrough is a result of mastering a combination of long-standing challenges comprising wafer-scale high-quality epitaxial growth, sidewall passivation, efficient photon extraction, and elegant bonding technologies, and promises significant advantages for augmented and virtual reality devices, wearables, and next-generation consumer electronics.

Application of isotope and multi-element fingerprinting in subregional milk authentication - The case of Ningxia, China.

Traceability of origin enhances the branding and safety of agricultural products. This study developed a subregional milk origin tracing method by selecting thirty large-scale farms: twenty-seven in Ningxia and three in Beijing. The farms were classified into six groups based on subregions: A (Yinchuan), B (Shizuishan), C (Qingtongxia), D (Yanchi), E (Zhongwei), and F (Beijing).

Maintenance OCS Were Used More Frequently Than Biologics in Patients with Uncontrolled GINA 4/5 Asthma in Germany in 2019.

Purpose: Asthma is affecting 4-5% of all adults (10% of children) in Germany, ≥ half are inadequately controlled. In 2019 up to 54 thousand patients suffered from severe uncontrolled asthma, 52% were treated/co-treated by pneumonologists. 45% of them had continuous oral corticosteroid (OCS)- and short-acting β2-agonist (SABA) overuse for ≥2 years.
