Acidification of Rainwater Due to Washout of Atmospheric Gaseous Pollutants

Deposition of Atmospheric Pollutants to a Limestone Building

Production of Lunar Concrete Using Molten Sulfur
A study has been undertaken by the authors and supported by NASA to study the feasibility of using lunar regolith with different binders such as molten sulfur, epoxy or hydraulic cement...

Tests for Biogenic Sulfuric Acid Corrosion in a Simulation Chamber Confirms the On Site Performance of Calcium Aluminate Based Concretes in Sewage Applications

Caustic Spray for Sewer Crown Corrosion Control
A novel method to control sewer crown corrosion which involves spray application of a caustic solution to the sewer crown is described. Corrosion control using this concept is based on...

Utilization of Waste Sulfur in Construction Materials and as a Stabilization/Encapsulation Agent for Toxic, Hazardous and Radioactive Waste

The Use of Phosphogypsum-Based Slag Aggregate in Hot Mix Asphaltic Concrete

The Use of Flue Gas Desulfurization Gypsum in Civil Engineering Applications

Sulfur as a Lunar Resource
Sulfur on the Moon may prove to be a satisfactory replacement in some uses for lighter volatile elements and their compounds. Although sulfur is not richly concentrated on the Moon, it...

In Situ Recovery of Water from Dormant Comet Cores & CI Carbonaceous Chondrites
Water and volatiles may be produced by drill holes into dormant comet cores or class CI or CM asteroids. This is modeled after in-situ mining as in the Frasch process sulfur mines of the...

FGD Waste Engineering Properties are Controlled by Disposal Choice

Screening Emissions Control Measures
Under the new Clean Air Act, electric utilities will be able to choose from a wider range of sulfur dioxide emissions control options than in the past. Among the newly available measures...

Gas Transfer Velocities on Lakes Measured with Sulfur Hexafluoride
Gas transfer velocities have been determined on five lakes ranging in size from 0.13 km2 to 450 km2 using...

Optimization Models for Acid Rain Control
A series of related optimization formulations are presented for developing and analyzing acid rain control strategies. These models span a wide array of approaches and reflect a similarly...

Kinetics of the Oxidation of Sulfonic Acids by Hydroxyl Radicals in Aqueous Solution

Beach Evolution in Sulphur Island
Seasonal variation of shore area of Sulphur Island is studied by analyzing aerial photographs of the island taken seasonally for the past two years. Analysis reveals that shore area in...

Sulfur Polymer Concrete for Special-Purpose Applications
Special-purpose sulfur concrete construction materials, based on sulfur polymer cement (SPC) and mineral aggregate, have been developed by the U.S. Bureau of Mines as part of a program...
