In the latest advance in nano- and micro-architected materials, engineers at Caltech have developed a new material made from numerous interconnected microscale knots. The knots make the material far tougher than identically structured but unknotted materials: they absorb more energy and are able to deform more while still being able to return to their original…

Knotted and woven fiber topologies in hierarchical intertwined materials. (A) Computer-aided design (CAD) rendering of a hierarchical octahedron lattice where each unit cell is composed of three rhombuses. The rhombus in the rectangular box is formed by two knotted fibers, one being highlighted in purple and tessellated vertically. (B) SEM images with color shading overlaid…

Graphical abstract. Credit: ACS Nano (2023). DOI: 10.1021/acsnano.2c06233 Non-alcoholic fatty liver disease is the most common chronic liver disease in the world. In its advanced form, non-alcoholic steatohepatitis (NASH), is curable when diagnosed and treated in its early stages. However, when left untreated, it could progress to the irreversible stage of liver cirrhosis and cancer,…

The newly developed antibody 6H4 fragments (Fabs) specific to Aβ oligomers, encapsulated in the polymeric nanomicelles (PMs), were peripherally administrated to AD model mouse for 10 weeks. In mice that were administered anti-AβO 6H4 Fabs in the PMs, various toxic Aβ species (Aβ oligomers, Aβ42s, N3pE Aβs, Aβs with toxic conformer) and the presence of…

Self-assembly of stacked kagome planes. Credit: Advanced Materials (2023). DOI: 10.1002/adma.202211197 Scientists have devised a way of fabricating a complex structure, previously found only in nature, to open up new ways for manipulating and controlling light. The structure, which naturally occurs in the wing scales of some species of butterfly, can function as a photonic…

Crystallinity and textural evolution. a XRD patterns of solids obtained at different times during the interzeolite transformation of FAU zeolite into MFI using CTPABr as both SDA and porogen (see treatment time in c). The strong band at ca. 26° 2θ corresponds to the graphite used as internal standard. b N2 physisorption isotherms at 77 K…

Vivid exhibition of high resolution pattern changes during multiple thermochromic processes: (a-i) photos of the display sample under the ever-increasing voltage of 0-8 V with gradually enhanced heater temperature. Credit: Ji Shulin There are many sputtered metal film heaters on the market, but they are opaque and can only be used on the back of…

Credit: CC0 Public Domain Due to their considerable efficiency, catalysts made of just a few atoms show great promise in the field of water treatment. In a new study, researchers looked into how to optimize the performance of these catalysts and make them viable for practical use. The results of the study, led by Prof.…
