Beams-driven structures are structures that use beams to support their weight. The beams are typically arranged in a way that distributes the weight of the structure evenly. Beams-driven structures are often used in buildings, bridges, and other complicated structures. Beams-driven ... Read More
The low-temperature electrochemical conversion of CO₂ to ethylene offers significant potential for reducing the chemical industry’s reliance on fossil fuels. Despite recent advancements, the key performance indicators—activity, selectivity, and durability—are insufficient for industrial ... Read More
Problem - The occlusion effect is an increase in loudness (sound pressure level) of your internal voice, especially in the low frequency range. Also, self-generated sounds such as chewing, swallowing, walking or running are amplified when the ears are blocked or occluded. Occlusion ... Read More
