Consumer technology today relies primarily on batteries to fulfill energy needs. Conventional batteries use chemical reactions to store energy, offering high energy density, which is to say that they provide long run times for our devices. However, they struggle with slow charging and degradation after just a few thousand use cycles. By contrast, supercapacitors use electrical charge separation to store energy. They can charge almost instantly and withstand more cycles without degradation.

A new theory proposes "unified theory of everything."vchal/iStockA unified theory of everything has long eluded scientists due to gravity being irreconcilable with the three other fundamental forces (electromagnetic, weak, and strong) described using quantum field theory (QFT). The fundamental discrepancy between the unification lies in how the two theories are described.

Modern electronic devices heavily rely on lithium-ion batteries, including smartphones, electric vehicles, and even aircraft. Even though these batteries are omnipresent in technology, traditional battery designs are reaching their limits in terms of how much energy they can store per unit of battery weight, known as energy density. Despite efforts to maximize the energy density, we are getting closer to the physical limits of what can be achieved with these traditional lithium-ion batteries.

In a new Nature Communications study, researchers have developed an in-memory ferroelectric differentiator capable of performing calculations directly in the memory without requiring a separate processor. The proposed differentiator promises energy efficiency, especially for edge devices like smartphones, autonomous vehicles, and security cameras. Traditional approaches to tasks like image processing and motion detection involve multi-step energy-intensive processes.
