Peering into materials down to the nanoscale in the COCOON lab
A new Tufts University imaging facility is doing something that most microscopy centers in the world cannot: allowing scientists to examine a butterfly wing, a living tissue or a microchip and reveal its physical structure, molecular chemistry and elemental composition across eve

New 3D COF structure could help tune porous materials for batteries and cleanup
A research team synthesized and determined the structure of a borate-linked 3D crystalline covalent organic framework, TCTP-COF, via electron diffraction for the first time. These findings will help scientists determine the structure-property relationships for other 3D COFs and f

New platform creates digital map for marine biobanks
New platform creates digital map for marine biobanks
A new digital platform developed under the leadership of CIIMAR is making Portugal's marine biodiversity more accessible by bringing together thousands of biological resources into a single access point. The Blue Biobanks Digital Research Platform aims to bridge scientific resear
Physicists finally build a quantum material predicted more than a decade ago
Physicists finally build a quantum material predicted more than a decade ago
Researchers have achieved a major milestone by creating a long-sought two-dimensional quantum material and confirming its unusual conducting edge states. The ability to control these states through strain could make the material a promising platform for future room-temperature qu
This electric field trick boosted heat flow by nearly 300%
This electric field trick boosted heat flow by nearly 300%
Researchers discovered that electricity can dramatically reshape how heat flows through certain ceramic materials, increasing heat conduction by almost threefold in a preferred direction. The unexpected result could lead to much more efficient cooling technologies and energy-savi
Secure glass containers for storing chemical waste through laser welding
Secure glass containers for storing chemical waste through laser welding
As the adoption of electric vehicles continues to grow, so does the need for the safe and permanent storage of battery materials and industrial chemical waste. Certain waste streams require disposal in what are known as Category IV landfills, which impose particularly stringent r
New method brings single-particle quality control to nanocrystal manufacturing
New method brings single-particle quality control to nanocrystal manufacturing
Nanocrystals are already used in millions of devices, including televisions, laptops and displays, and are considered key materials for the next generation of quantum, sensing and solar technologies. However, they have not yet fully realized their potential. One major reason is t

Self‑building molecular rings bring next‑generation drug delivery and smart materials clos
Rotaxanes are dumbbell-shaped mechanically interlocked molecules in which one or more ring-shaped molecules are threaded through a linear segment, known as the axle. To keep the ring from sliding off, two bulky groups, sometimes called stoppers, are added to the ends of the axle.
New imaging method offers fresh insight into LED materials
New imaging method offers fresh insight into LED materials
Light Emitting Diodes (LEDs) are used in everything from household lighting and mobile phones to large display screens. Improving their efficiency could reduce energy use and enhance performance across a wide range of technologies. A new study involving researchers from the Unive
