Microwave Reactor

We have developed a microwave reactor.

Our proposal is a multi-emitter microwave device that captures gases, CO2 from engines, and reforms them into calcium carbonates, And The Calcium Carbonate is of high value for gas and oil drilling. Since it saves money by preventing drilling fluids from being lost in cracks, when trepanning.

Electro-Oxidative Wastewater Treatment and Coupled Hydrogen Generation Using PFAS as a Test Case

Hydrogen combustion is eco-friendly: its combustion returns water to the ecosystem. Water electrolysis – a green hydrogen concept – coupled with proton permeable membrane technology is one way to generate hydrogen. The main challenge with this technique is the high electric power consumption required to split water.

High-Entropy Sodium-Ion Battery: A Sustainable, Scalable, and Safe Energy Storage Solution

The growing global demand for sustainable and cost-effective energy storage systems has exposed key limitations in current lithium-ion battery (LIB) technologies—namely, resource scarcity, high costs, and safety concerns. Our high-entropy sodium-ion battery (HE-SIB) addresses these issues by replacing lithium with sodium, an abundant and low-cost alternative,
