These materials retain a "memory" of their original form. This capacity is known as the shape memory effect (SME), and it may occur in shape memory alloys (SMAs) and polymers (SMPs), but it is also ...

Sustainable 4D Printable Biobased Shape Memory Polymers with Linear Tunability and Multistimuli Actuation for Advanced Applications. Small Science . DOI: 10.1002/smsc.202500104, https ...

Four-dimensional (4D) printing is an additive manufacturing (AM) process in which three-dimensional (3D) printing is combined with smart materials that have shape memory. During 4D printing, the smart ...

Additive manufacturing – or 3D printing – is 30 years old this year. Today, it’s found not just in industry but in households, as the price of 3D printers has fallen below US$1,000. Knowing ...

Enter the world's first 512Gb (that's gigabit, not gigabyte) triple level cell (TLC) 4D NAND flash memory—coming right to our desks some time in early 2023.

SK Hynix, a semiconductor leader, has made a significant stride in the NAND Flash industry by revealing a prototype of its pioneering 321-layer 4D NAND at the Flash Memory Summit (FMS) 2023 held ...

SK hynix's 238-layer 4D NAND flash memory paves the way for faster and potentially cheaper solid state drives (SSDs) and smartphone storage.
