Atmospheric water irrigation enabled by super moisture absorbent gels
Overview
The global population is projected to reach 9.6 billion people by 2025, requiring food production to increase by 70% to meet the demand of the huge population. Water is most limiting natural resource for agricultural production due to the freshwater shortage and enormous need for irrigation. Dry cropland accounts for 84% of the cultivated...

Electrochemical production of solar-grade silicon films from SiO2
Background Silicon thin films are an important limitation for solar photovoltaic cells. Currently, manufacturing of these films are from single crystal silicon and a large amount of raw material is wasted. Single crystal silicon is not a cheap commodity. Thus, the sawing process used on single crystal silicon is costly not only from a manufacturing...

Generating water from air
Background Air water generation (AWG) is a technology that extracts water molecules from the relative humidity in the atmosphere, passes the condensed water vapor through a filter to produce a drinkable source of water. This type of technology is most beneficial in environments that do not produce large amounts of drinkable water such as arid climates...

A new way to extract lithium chloride from liquid and solid solutions
Lithium chloride (LiCl) is a critical lithium containing material involved in producing battery-grade lithium hydroxide (LiOH). LiOH is required as a precursor material for many of the high-performance Li+-ion battery cathode chemistries in use today for portable electronic applications from laptops to electric vehicles. However, current battery production...
