Engineering is the design and construction of systems and structures for influencing the world around us and enhancing our experience within it. Engineers use the fundamental principles of mathematics, physics and chemistry to create machines that enable us to travel faster, provide improved medical care, and process more complicated information.
Electrifying nonaqueous thermocatalytic reactions is challenging. Now, a multiphase approach that uses aqueous electrochemistry to drive a nonaqueous reaction through aqueous–nonaqueous interfacial proton-coupled electron transfer is developed for the production of hydrogen peroxide.
iAutoEvoLab is an industrial-grade automation platform for the growth-coupled, continuous evolution of proteins in yeast. Its high throughput, efficiency and effectiveness were demonstrated by the evolution of a DNA-binding protein (LmrA), a lactate sensor (LldR) and a RNA polymerase–capping enzyme fusion protein.
By incorporating a laser-induced solidification process into a direct ink writing process, free-standing thermoset structures can be built with tunable electrical and mechanical properties.
Wireless communication, non-destructive testing and material identification propel the development of the Terahertz frequency region. Here the authors present a fast tunable measurement system with a frequency coverage of 6.5 THz suitable for metrological applications.
An article in Advanced Materials introduces a soft hydrogel microrobot that assembles 3D cell spheroids, delivers localized photothermal stimulation and provides real-time temperature sensing.
A study in Optics Express reports the design of a simple dielectric metasurface structure composed of lithium niobate defect disks that enhances the generation of entangled photon pairs through spontaneous parametric down-conversion.
