The Emerging 4D Printing of Shape‐Memory Thermomorphs for Self‐Adaptative Biomedical Implants

Advanced Functional Materials, EarlyView.
4D printing enables the creation of smart implants that adapt to changing conditions in the human body over time. At the core of this technology are shape‐memory thermomorphs (SMTMs). This review offers an in‐depth analysis of 4D printing with SMTMs, emphasizing the latest advancements in smart materials, stimuli, programming principles, and their ...

Evidence of Long‐Range Dzyaloshinskii–Moriya Interaction at Ferrimagnetic Insulator/Nonmagnetic Metal Interfaces

Advanced Functional Materials, EarlyView.
This study demonstrates that in sputter‐deposited Tb3Fe5O12 (TbIG)/nonmagnetic metal (NM) heterostructures, the interfacial Dzyaloshinskii–Moriya Interaction (DMI) originates at the TbIG/NM interface. Furthermore, measurements suggest a significant interfacial DMI arising from a second non‐local interface, created by inserting a Cu spacer layer between

A Gym for Cells—Direct Laser Writing of Magnetic Multilayered Micro Actuators for Mechanical Stimulation of Cells

Advanced Functional Materials, EarlyView.
Surface‐attached multilayer micromagnet systems are fabricated by two‐photon crosslinking. The pillar‐shaped micro actuators consist of a soft and flexible surface‐attached cell‐repellent hydrogel layer at the bottom, acting as a hinge and a cell‐adhesive hydrophobic polymer filled with magnetic nanoparticles.

On how finite β and three-dimensional magnetic perturbations affect the instability of toroidal ion temperature gradient mode

Nuclear Fusion
The effects of finite $\beta $ (the ratio of plasma kinetic pressure to magnetic pressure) and three-dimensional (3D) magnetic perturbations (MPs) on the instability of toroidal ion temperature gradient (ITG) mode are studied in this work. The expression

Electrically Induced Negative Differential Resistance States Mediated by Oxygen Octahedra Coupling in Manganites for Neuronal Dynamics

Advanced Functional Materials, EarlyView.
The negative differential resistance is exploited, using a La0.67Sr0.33MnO3 thin film network to demonstrate various neuronal functionalities of the human brain, such as leaky‐integrate‐fire and oscillatory patterns. Transmission electron microscope studies show local modification in oxygen octahedra in the network leads to co‐existing phases ...

Fusion It is time to color outside the lines [PDF]

arXiv
There has been some good news, and some bad news in the controlled fusion community recently. The good news is that the Lawrence Livermore National Laboratory (LLNL) has recently produced a burning plasma. It succeeded on several of its shots where ~1.5-2 megajoules from its laser (National Ignition Facility, or NIF) has generated ~ 1.3-3 megajoules of

New option for solving the climatic problems with non-thermal laser driven boron fusion and ultrahigh magnetic fields [PDF]

arXiv, 2014
In contrast to the broad stream of sustainable developments on fusion energy, new aspects are developed now by applying ultra-short, ultra-powerful laser pulses in a plasma-block ignition scheme by avoiding the well known difficulties of thermal-pressure instabilities and losses through using electro-dynamic non-thermal energy conversion.
