Organic Ink Multi-Material 3D Printing of Sustainable Soft Systems.

Drawing inspiration from nature, soft materials are at the core of a transformation toward adaptive and responsive engineered systems, capable of conquering demanding terrain and safe when interacting with biological life. Despite recent advances in 3D printing of soft materials, researchers are still far from being able to print complex soft systems where a multitude of different components need to work together symbiotically. Closing this gap necessitates a platform that unites diverse materials into one synergetic process.

Ultrafast small-scale soft electromagnetic robots.

High-speed locomotion is an essential survival strategy for animals, allowing populating harsh and unpredictable environments. Bio-inspired soft robots equally benefit from versatile and ultrafast motion but require appropriate driving mechanisms and device designs. Here, we present a class of small-scale soft electromagnetic robots made of curved elastomeric bilayers, driven by Lorentz forces acting on embedded printed liquid metal channels carrying alternating currents with driving voltages of several volts in a static magnetic field.

Stretchable and Biodegradable Batteries with High Energy and Power Density.

Realizing a sustainable, technologically advanced future will necessitate solving the electronic waste problem. Biodegradable forms of electronics offer a viable path through their environmental benignity. With both the sheer number of devices produced every day as well as their areas of application ever increasing, new concepts of degradable batteries able to sustain the high power demands of modern electronics must be developed.

Resilient yet entirely degradable gelatin-based biogels for soft robots and electronics.

Biodegradable and biocompatible elastic materials for soft robotics, tissue engineering or stretchable electronics with good mechanical properties, tunability, modifiability or healing properties drive technological advance, and yet they are not durable under ambient conditions and do not combine all the attributes in a single platform. We have developed a versatile gelatin-based biogel, which is highly resilient with outstanding elastic characteristics, yet degrades fully when disposed. It self-adheres, is rapidly healable and derived entirely from natural and food-safe constituents.

Application of Ti-in-zircon thermometry to granite studies: problems and possible solutions.

The application of the Ti-in-zircon thermometer to granitic rock requires consideration of and during zircon crystallization. Thermodynamic software programs such as rhyolite-MELTS or Perple_X permit the estimation of and values from whole-rock geochemical data as a function of pressure and temperature. Model calculations carried out on a set of 14 different granite types at 2 kbar, 5 kbar, and HO = 3 wt% show during zircon crystallization close to 1 (0.

An in-situ simulation-based educational outreach project for pediatric trauma care in a rural trauma system.

Background: Outcome disparities between urban and rural pediatric trauma patients persist, despite regionalization of trauma systems. Rural patients are initially transported to the nearest emergency department (ED), where pediatric care is infrequent. We aim to identify educational intervention targets and increase provider experience via pediatric trauma simulation.
