Solar-driven interfacial evaporation has emerged as an efficient and sustainable way to generate freshwater from seawater to address the crisis of drinkable water. Though rational designs of photothermal materials and structures are essential to the interfacial solar vaporization process, the...

Proton exchange membrane fuel cells (PEMFCs) durability has been severely hindered by poor stability of carbon support in the cathodic Pt-based catalyst. Herein, a high-surface-area nitrogen doped graphitic nanocarbon (N-G-CA) with mesopores is developed as Pt support to address PEMFCs...

Lithium-sulfur (Li-S) batteries have attracted significant attention as next-generation energy storage systems owing to their high theoretical specific capacity (1675 mAh g –1 ) and energy density (2567 Wh kg –1 ) . However, the low electrical conductivity of S and the dissolution of...

Corrosion performance of stainless steels 316L and 347H, and nickel alloys 625 and 800H were investigated in molten sodium carbonate/potassium carbonate eutectic salt, which is a promising phase change material for use in thermal energy storage applications, at 750 °C under argon and CO2...

Aluminum matrix reinforced by "in situ" α-Al2O3 nanoparticles are fabricated via a direct chemical reaction between molten aluminum and TiO2 nanopowder under molten salt layer at 700-8000 C under air atmosphere, and the morphologies, sizes and distributions of the in situ particles, as well as...

This paper studies the long-term effect of taxation on economic geography and development. We rely on a unique natural experiment in place during France’s ancien régime: the salt tax. Introduced in the late 13th century and abrogated by the French Revolution in 1789, the salt tax was not...

The production and use of carbon nanotubes (CNTs) have become extremely wide within the last decade. Hence, the high interest in producing non-expensive and quality CNTs has motivated many research projects. This research considers the design and development of new technology for producing...

Is it feasible to build desalination plants for the co-production of salt and freshwater from U.S. seawater that could lead to a restructuring of supply chains for salt imports? As it is predicted that climate change will increase water stress worldwide, an increasing number of countries are...

Iodine deficiency is the leading cause of preventable mental retardation in the world today. The condition, which was common in the developed world until the introduction of iodized salt in the 1920s, is connected to low iodine levels in the soil and water. We examine the impact of salt...

Long-term follow-up of early childhood health interventions is important for human capital accumulation. We provide experimental evidence on child health and human capital outcomes from the longer-term follow-up of a school-based nutrition intervention in India. Using panel data, we examine the...

Sugary drinks taxes have been implemented around the world and governments around the world are considering extending these taxes to address concerns about rising obesity. We demonstrate the range of impacts a tax on added sugar and salt could have on purchases of food at home and out of the...

Salinity in surface waters is on the rise throughout much of the world. Many factors contribute to this change, including increased water extraction, poor irrigation management, and sea-level rise. To date no study has attempted to quantify the impacts on global food production. This paper...

Traditional steam methane reforming facilities for producing hydrogen not only consume a large amount of natural gas, but also emit a lot of greenhouse gas. Considering the utilization of clean energy, the reduction of carbon dioxide emission, and the production of chemicals, this paper...

This paper examines the effects of a massive salt iodization program on human capital formation of school-aged children in China. Exploiting province and time variation, we find a strong positive impact on cognition for girls and no effects for boys. For non-cognitive skills, we find the...

We present experimental evidence on the impact of the use of double-fortified salt in school meals on anemia, cognition, and the learning outcomes of primary school children in rural Bihar, one of the poorest regions of India. We find that year-long intervention had statistically significant...

In 1924, The Morton Salt Company began nationwide distribution of iodine-fortified salt. Ac- cess to iodine, a key determinant of cognitive ability, rose sharply. We compare outcomes for cohorts exposed in utero with those of slightly older, unexposed cohorts, across states with high versus low...

In this viewpoint, I evaluate the potential for state and local governments to raise revenue in a post-Quill world. I then examine dynamic sales and how they work, assess the state of current technology affecting online sales, and propose dynamically taxing electronic transactions (including...

State governments are considering new charitable tax credits designed to circumvent the 2017 federal tax overhaul's cap on state and local tax deductions. Will these plans work? This essay argues that the answer is: yes, but with some qualifications
