Forgotten property of the electron
The orbital angular momentum of electrons has long been considered a minor physical phenomenon, suppressed in most crystals and largely overlooked. Scientists have now discovered that in certain materials it is not only preserved but can even be actively controlled. This is due to a property of the crystal structure called chirality, which also influences […]
Designing the future of clean energy: Janus heterobilayers lead the way
Janus heterobilayers -- dual-sided materials with unique properties -- may be the key to efficiently creating clean hydrogen fuels.
Stability solution brings unique form of carbon closer to practical application
Carbyne, a one-dimensional chain of carbon atoms, is incredibly strong for being so thin, making it an intriguing possibility for use in next-generation electronics, but its extreme instability made it nearly impossible to produce at all, let alone produce enough of it for advanced studies. Now, an international team of researchers may have a solution.
One glass, full color: Sub-millimeter waveguide shrinks AR glasses
Augmented-reality (AR) technology is rapidly finding its way into everyday life, from education and healthcare to gaming and entertainment. However, the core AR device remains bulky and heavy, making prolonged wear uncomfortable. A breakthrough now promises to change that. A research team has slashed both thickness and weight using a single-layer waveguide.
Turning non-magnetic materials magnetic with atomically thin films
The rules about magnetic order may need to be rewritten. An international team of researchers found that it was possible to turn a non-magnetic material into a magnetic material by slicing it into thin films.
New microscope reveals heat flow in materials for green energy
Scientists have developed a new microscope that significantly improves the way heat flow in materials can be measured. This advancement could lead to better designs for electronic devices and energy systems.

Featured image of how to use timers in PIC16F877A

In this tutorial, we will learn what are "Timers"; we will explain this with examples using the Microcontroller PIC16F877A. For this tutorial is may be helpful to understand the basics of turning an LED on and off, which is explained in one of my previous tutorials on LEDs. In this ...
