Solar trackers have been used for decades. Trackers aim solar panels to continuously face the sun to maximize the energy captured. Concentrated photovoltaics (CPV), like conventional photovoltaic systems, generate electricity from sunlight. Compared to conventional photovoltaic systems, CPV are more efficient.

Overarching Challenge: How does one identify SERM (i.e. estrogen-like) molecules based upon quantum fundamentals? A pharmacophore is that set of properties, carried within a molecular framework, responsible for a drug’s biological activity.

A spray of spherical wastewater droplets into an extremely cold gas causes an ice shell to form and grow thicker and thicker as it falls downward in the spray chamber.

The growing globalization of our society, the difficulty of communication because of the language barrier the new technologies possibilities from different software platforms requires a new and updated communication system that could improve represent our society communications. Such system could simplify our communications ,

For decades, seeing eye dogs have been used by visually impaired or blind individuals. These highly trained dogs specialize in keeping the user safe from obstacles and hazards during their daily lives when they travel. While these exceptional animals are a valuable companion to the user,

In this work, we explore the implementations of the buck converter and the boost converter, using Back-End-of-Line (BEOL) Nano-electromechanical (NEM) relays, for on-chip voltage conversions.

Our study exploits the design approach for relay-based DC-DC converters using an inductorless,

This muffler is basically a combination of absorptive and reflective type and has 3 layers.

The inner one content a converging and diverging type of venturi with holes on it and a flap (can be a rhodium/palladium) in between the C/D venturi which diverts the exhaust gases.


Climate change is placing hardship on 3 billion people in poverty. Dysentery and spread of disease can be prevented if they could just boil water, keep food chilled, and power small appliances. For every tonne of carbon dioxide we emit into the atmosphere,

The mission of this device is energy savings. I call it Green It, but any name can be applied. It's designed to detect and report common and sometimes costly failures when added to an HVAC system installed in most homes and small businesses.

What is proposed is a trailer with extra lithium batteries for electric SUV's to allow them to go to remote places where recharging would not be available.
