Gas Delivery System To Provide Induced Partial Saturation Through Solute Transport And Reactivity For Liquefaction Mitigation
US Patent:
2013033, Dec 19, 2013
Filed:
Aug 19, 2013
Appl. No.:
13/969885
Inventors:
Michac YEGIAN - Lexington MA, US
Akram ALSHAWABKEH - Franklin MA, US
Akram ALSHAWABKEH - Franklin MA, US
Assignee:
NORTHEASTERN UNIVERSITY - Boston MA
International Classification:
E02D 3/12, G01N 29/02, C09K 17/00
US Classification:
73 6178, 4051287
Abstract:
A system and method for providing a partial level of saturation to a mass of sand, through generation of gas bubbles, as a way to prevent liquefaction during earthquakes. The system includes a solution that is operable to generate gas bubbles and a solution generator that prepares the solution. A conduit delivers the solution to the sand, so that the solution generates the gas bubbles during and after being delivered to the sand. A probe may be used to determine whether the sand is susceptible to liquefaction before the solution is delivered and to assess a change in degree of partial saturation after the solution has been delivered.
Method Of Containing And At Least Partially Remediating Contaminants In Soils, Including Sediments
US Patent:
2006022, Oct 5, 2006
Filed:
Aug 2, 2005
Appl. No.:
11/194641
Inventors:

International Classification:
B09C 1/08
US Classification:
405129650, 405128750
Abstract:
In one application for containing and remediating contaminants in sediments, employing a geocomposite eliminates the need for a thick cap or removal and subsequent ex situ treatment of the sediment. A geocomposite with at least one layer of reactive material is placed over the area to be remediated. A layer of available surcharge materials such as sand, gravel, or riprap covers the geocomposite. The weight of the surcharge materials causes pore water to flow from the sediment through the reactive layer or layers. Contaminants may be trapped in this reactive layer or layers. A top or bottom layer, or both a top and bottom layer, may be provided to inhibit incursion from outside the sediment layer, while permitting appropriate flow direction of pore water into the reactive layer or layers.

Electrolytic Transformation Of Water Contaminants
US Patent:
2014006, Mar 6, 2014
Filed:
Feb 6, 2012
Appl. No.:
13/983749
Inventors:
Akram Alshawabkeh - Franklin MA, US

Xuhui Mao - Malden MA, US
Assignee:
NORTHEASTERN UNIVERSITY - Boston MA
International Classification:
C02F 1/461
US Classification:
205758, 204660, 204674, 205761
Abstract:
Methods and apparatuses to transform contaminants in water by electrolytic processes are described. In some embodiments, the apparatuses and electrolytic processes couple an anode comprising iron and a high specific surface area cathode. Methods and apparatuses described herein provide advantages over conventional apparatuses and methods such as, for example, cost savings, efficiency, environmentally benign impact and versality for a variety contaminants.
