While sustainable solar energy can potentially meet our global power needs, it has one major flaw. When sunlight disappears, solar panels stop generating electricity. The problem is that while they do an excellent job of converting light into power, they are not so good at storing the energy they collect.

One solution is to use materials known to capture heat and release it later, such as phase change materials (PCMs)...

Master Pressure Advance for Sharp Corners and Smooth 3D Prints

Successful 3D printer calibration is the fundamental bridge that takes your production quality from “good” to “perfect.” While most enthusiasts focus on temperature, mastering Pressure Advance is the true secret to professional-grade results. This guide serves as a vital technical extension of our 3D Printing Guide Review and complements our deep-dive into Precision 3D Printer Calibration.

What is Pressure Advance in 3D Printing?

Pressure Advance (known as Linear Advance in Marlin firmware) is a predictive technology that manages the internal pressure of the hotend. Because 3D printing filament is slightly elastic, the extruder often pushes too much plastic during deceleration and too little during acceleration. This phenomenon causes bulging corners and uneven surfaces.

A new technology allows light to be “designed” into desired forms, potentially making AI and communication technologies faster and more accurate. A KAIST research team has developed an “integrated photonic resonator”โ€”a core component of next-generation optical integrated circuits that process data using light. Interestingly, the research was led by an undergraduate student. This technology is expected to serve as a key foundation for next-generation security technologies such as highspeed data processing and quantum communication.

The resonator developed by the research team of Professor Sangsik Kim from the School of Electrical Engineering, in collaboration with Professor Jae Woong Yoon’s t...

Smart cable sharing gives quantum computers a big boost

An artistโ€™s rendering of time multiplexing of control signals to a quantum computer.
The control signals for single-qubit gates (short blocks) and two-qubit gates (long blocks) travel through common cables (tunnels) to switches, which distribute them among the qubits (spheres) based on switching signals (diamonds). By ordering the control signals in a clever way, akin to playing Tetris, traffic jams in the flow of control signals can largely be avoided and programs on the quantum computer can be executed almost as fast as if each qubit had its own cable for control signals.

A major obstacle in the development of powerful quantum computers is the growing number of cables required to control a computer as the number of qubits increases...
