Study links deterioration of concrete and asphalt to trace quantities of organic matter; diesel exhaust, windshield washer fluids

Green Car Congress

During their experiments, the scientists happened to notice that a strange odor developed when commercial cement was mixed with water. Of the organic matter present in cement, phthalates have the highest effect on deterioration more than phosphates and AE water reducing agents. CT scans showing cracks in damaged concrete.

SwRI CAT-DEF reduces heavy-duty diesel emissions to meet CARB 2027 NOx requirements

Green Car Congress

CAT-DEF—Catalyzed Diesel Exhaust Fluid—is an SwRI-developed catalyst- and surfactant-modified diesel exhaust fluid (DEF) solution. The internally funded advancement successfully reduced heavy-duty diesel engine nitrogen oxide (NO x ) emissions to meet the California Air Resources Board (CARB) 2027 standards.

Borla Performance Industries developing muffler/membrane unit for exhaust water extraction with ORNL nanopore membrane technology

Green Car Congress

Borla Performance Industries , a leader in the design and manufacture of stainless steel performance exhaust, has an option to license a novel nanopore membrane technology developed at Oak Ridge National Laboratory (ORNL). The heat recovered could serve to preheat boiler feed water, thus providing an energy savings.

First online measurement of gaseous sulfuric acid in diesel exhaust helps clarify role in formation of nucleation particles

Green Car Congress

Researchers in Germany and Finland report the first online measurement of gaseous sulfuric acid (GSA) in the exhaust gas of a modern heavy-duty diesel engine in an effort to quantify the role of low-vapor-pressure gases in the formation of nucleation particles (NUP).

EPFL team develops on-board system to capture CO2 from trucks; reducing emissions by 90%

Green Car Congress

The EPFL system captures CO 2 directly in the trucks’ exhaust system and liquefies it in a box on the vehicle’s roof. First, the vehicle’s flue gases in the exhaust pipe are cooled down and the water is separated from the gases. Researchers at EPFL have patented a new concept that could cut trucks’ CO 2 emissions by almost 90%.

UCLA study shows how air pollution can lead to damage to brain cells; zebrafish and Parkinson?s

Green Car Congress

Published in the journal Toxicological Sciences , the findings show that chemicals in diesel exhaust can trigger the toxic buildup of a protein in the brain called alpha-synuclein, which is commonly seen in people with the disease. Barnhill added certain chemicals found in diesel exhaust to the water in which the zebrafish were kept.
