Addressing key challenges of photoresponsive, visible light 3D printing

Addressing key challenges of photoresponsive, visible light 3D printing

Vat photopolymerization, a light-based 3D printing technique, conventionally relies on UV light to rapidly transform liquid resins into intricate solid objects. However, the use of visible light as an alternative approach has gained significant attention, particularly for its promising applications in tissue engineering and soft robotics.

Cracking the code of performance degradation in solid oxide cells at the atomic level

Cracking the code of performance degradation in solid oxide cells at the atomic level

Researchers have elucidated the mechanism of the initial degradation phenomenon that triggers the performance drop of high-temperature solid oxide electrolysis cell systems, using advanced transmission electron microscopy. Unlike previous studies, which analyzed the final stages of degradation at the micrometer scale, this study successfully verified the initial changes in electrolysis cell materials at the nanometer scale.

Transforming marine waste and carbonated water into hydrogels via CO₂ release behavior

Transforming marine waste and carbonated water into hydrogels via CO₂ release behavior

Hydrogels, which are soft materials made of water-filled, crosslinked polymer networks, have a wide range of uses, from wound dressings to enhancing soil moisture for plant growth. They are formed through a process called gelation, where polymers in a solution are linked together to form a gel.

Egg-shaped galaxies may be aligned to the black holes at their hearts, astronomers find

Egg-shaped galaxies may be aligned to the black holes at their hearts, astronomers find

Black holes don't have many identifying features. They come in one color (black) and one shape (spherical). The main difference between black holes is mass: some weigh about as much as a star like our sun, while others weigh around a million times more. Stellar-mass black holes can be found anywhere in a galaxy, but the really big ones (known as supermassive black holes) are found in the cores of galaxies.

Theoretical astrophysicist proposes solution to enigma of Crab Nebula's 'zebra' pattern

Theoretical astrophysicist proposes solution to enigma of Crab Nebula's 'zebra' pattern

A theoretical astrophysicist from the University of Kansas may have solved a nearly two-decade-old mystery over the origins of an unusual "zebra" pattern seen in high-frequency radio pulses from the Crab Nebula.

Paper wasps study shows that body size is larger in habitats nearer the equator

Paper wasps study shows that body size is larger in habitats nearer the equator

A study of the correlation between environmental variables such as latitude and body size in paper wasps (genus Polistes) by a group of Brazilian researchers concludes that the nearer the habitat of a species to the equator, the larger its body size. The genus is widely distributed around the world and serves as a model for sociobiological and ecological studies.

Tree islands restore nature in oil palm plantations: Researchers look into native species recovery in Sumatra

Tree islands restore nature in oil palm plantations: Researchers look into native species recovery in Sumatra

Southeast Asia's tropical forests are renowned for their biodiversity, but at the same time face significant threats from the expansion of oil palm plantations. With global demand for palm oil rising, the urgency for effective restoration strategies in these landscapes has become critical.

Global glacier melt: Major mass loss expected by 2100

Global glacier melt: Major mass loss expected by 2100

Glaciers around the world are shrinking at an alarming rate, threatening sea-level rise, water availability, biodiversity, and ecosystem stability. A new study led by researchers from ETH Zurich and Vrije Universiteit Brussel and published in The Cryosphere provides the most comprehensive projections to date, projecting the future of over 200,000 glaciers—excluding those in Greenland and Antarctica—under the newest climate scenarios.

Meltwater from Greenland and the Arctic is weakening ocean circulation to speed up warming down south, model suggests

Meltwater from Greenland and the Arctic is weakening ocean circulation to speed up warming down south, model suggests

A vast network of ocean currents nicknamed the "great global ocean conveyor belt" is slowing down. That's a problem because this vital system redistributes heat around the world, influencing both temperatures and rainfall.
