The Problem With Diesel [PDF]

open access: yesJNCI Journal of the National Cancer Institute, 2012
Diesel engine exhaust (DEE) is a complex mixture of substances characterized by polycyclic aromatic hydrocarbons (PAH) surrounding an elemental carbon core. Diesel engines have a wide range of industrial applications including on-road equipment (most heavy and medium duty trucks and buses use diesel engines) and off-road applications in the mining ...

Testing the Indicators of Diesel Vehicles Operating on Diesel Oil and Diesel Biofuel

open access: yesEnergies, 2022
The growth in the number of cars and the increasing demand for fuels require scientific work to develop alternative fuels. The energy crisis, which is becoming more and more evident, is not unimportant. The manuscript presents an analysis of the possibility of using agricultural biofuels to power a diesel engine.

Numerical simulation of diesel combustion based on n-heptane and toluene

open access: yesPropulsion and Power Research, 2019
Considering the self-ignition characteristic and C/H ratio, n-heptane and toluene (6:4 by mass) are chosen to constitute diesel surrogate fuel, and a reduced oxidation mechanism was developed.

Ketal Protection of Glycerol for Selective Electrosynthesis of Glyceric Acid in Highly Alkaline Media

open access: yesAngewandte Chemie, EarlyView.
Using a ketal‐protected glycerol derivative (solketal) as the oxidation substrate enables site‐selective electrooxidation that suppresses C–C cleavage on non‐noble catalysts. Highly alkaline conditions promote reactive solketal alkoxide formation, weaken the Cα─H bond to facilitate dehydrogenation, and buffer local acidification, enabling a record‐high

Laser Activation for Highly Boron-Doped Passivated Contacts

open access: yesSolar, 2023
Passivated, selective contacts in silicon solar cells consist of a double layer of highly doped polycrystalline silicon (poly Si) and thin interfacial silicon dioxide (SiO2). This design concept allows for the highest efficiencies.
