With 4D printing, the objects can change shape or properties using external stimuli such as temperature, light, pH, magnetic field, electricity, and moisture. Additionally, the changes in shape or ...

Laser powder bed fusion, a 3D-printing technique, offers potential in the manufacturing industry, particularly when fabricating nickel-titanium shape memory alloys with complex geometries. Although ...

(Nanowerk Spotlight) Millions suffer from bone defects worldwide, caused by disease, injury or age-related conditions. Traditional treatment options include bone grafting, where bone tissue is ...

3D printing, an additive manufacturing (AM) technique, has the potential to revolutionize how we produce objects that we want and need in the modern world. Among other developments, innovations in ...

(Nanowerk Spotlight) The next generation of robots may not look anything like the rigid, mechanical machines we’re used to. Instead, imagine a robot that moves more like an octopus or a human hand, ...

Smart polymers with “life-like” properties: due to dynamic chemical bonds the micrometric 3D structures can grow eight-fold in just a few hours and harden. Scale: 20 micrometres (µm). This image may ...

In a development poised to shift the paradigm in cardiovascular medicine, researchers are designing fully polymeric heart valves to replace traditional metallic implants. These valves, crafted from ...

Infected bone defects arise in conditions such as osteomyelitis and post-traumatic bone infections, where microbial persistence and immune imbalance prevent effective healing. Standard treatments rely ...

Scientists at Friedrich-Alexander-Universität Erlangen-Nürnberg have created materials that change their shape and mechanical properties when exposed to light. By integrating nanoscale molecular ...
