A freeform multimaterial assembly process (FMAP) is demonstrated, synchronizing laser induction with 3D printing for seamlessly integrating multimaterials into 3D objects, enabling streamlined, flexible, and precise electronic device fabrication.
Researchers at Fraunhofer IPM have developed a contactless flow measurement method based on magnetic fields. For the first time, they have been able to show the quantitative impact of the flow profile on the magnetic signal. This opens up new possibilities for improving the measurement method.
The results were recently published in the Journal of Applied Physics.
There are many manufacturing processes across various industries where flowing liquids play a key role. Controlling or automating such processes requires reliable data on the flow rate of the liquids. The magnetic field-based flow measurement technique developed at Fraunhofer IPM provides accurate flow data without any contact with the liquid.
One of the most common problems is spills of the salty brine that’s a toxic byproduct of pumping oil. Another is over-or under-pumping that can lead to machine failure and methane leaks. (The oil and gas industry is the largest industrial emitter of methane in the U.S.) Then there are extreme weather events, which range from winter frosts to blazing heat, that can put equipment out of commission for months. One of the wildest problems Sebastien Mannai SM ’14, PhD ’18 has encountered are hogs that pop open oil tanks with their snouts to enjoy on-demand oil baths.
Mannai helps oil field owners detect and respond to these problems while optimizing the operation of their machinery to prevent the issues from occurring in the first place. He is the founder and CEO of Amplified Industries, a company selling oil field monitoring and control tools that help make the industry more efficient and sustainable.
Amplified Industries’ sensors and analytics give oil well operators real-time alerts when things go wrong, allowing them to respond to issues before they become disasters.
Researchers at the Paul-Drude-Institute for Solid State Electronics (PDI) have observed a novel modulation regime characterized by the emergence of previously unseen “acceleration beats” in a modulated semiconductor-based laser.
As they detail in a paper published today in Nature Communications, the key—and somewhat counterintuitive—feature of this novel regime is the ability to coherently manipulate quantum systems using modulation periods longer than the coherence time, provided that the modulation amplitude is large enough.
Harmonic modulation of light sources, such as lasers, is the cornerstone of many modern and emergent telecommunications technologies. In this regard, two regimes of modulation are well-known: the adiabatic regime and the non-adiabatic regime.
To take a picture, the best digital cameras on the market open their shutter for around around one four-thousandths of a second.
To snapshot atomic activity, you’d need a shutter that clicks a lot faster.
With that in mind, scientists have unveiled a way of achieving a shutter speed that’s a mere trillionth of a second, or 250 million times faster than those digital cameras. That makes it capable of capturing something very important in materials science: dynamic disorder.
Tesla’s new patent reveals an advanced sanitization system for Robotaxis, ensuring clean interiors using sensors, UV light, and HVAC methods.
Transistors are semiconductor devices that regulate current, amplify signals, and act as switches, forming the foundation of modern electronics.
A study has unlocked new dimensions in understanding the ultrafast processes of charge and energy transfer at the microscale. The research delves into the dynamics of microscopic particles, providing insights that could revolutionize semiconductor and electronic device development.
Researchers at EPFL have discovered that by shining different wavelengths (colors) of light on a material called magnetite, they can change its state, e.g., making it more or less conducive to electricity. The discovery could lead to new ways of designing new materials for electronics such as memory storage, sensors, and other devices that rely on fast and efficient material responses.
A groundbreaking way of measuring fluid buildup in the body allows chronic heart failure patients to monitor their condition and treat it independently with a physician-approved response.
Tel Aviv-based startup Vectorious has created a tiny pressure sensor that is implanted directly into the heart. It is the only sensor in the world that measures the pressure in the left atrium (one of the heart’s two upper chambers) and is able to identify increases in that pressure caused by a buildup of fluid in the body.
This data on the left atrial pressure (LAP) is then transmitted to an app for the patient and their doctor.
