IOP Conference Series: Materials Science and Engineering, 2016 The paper analyzes the exhaust emissions from farm vehicles based on research performed under field conditions (RDE) according to the NTE procedure. This analysis has shown that it is hard to meet the NTE requirements under field conditions (engine operation in the NTE zone for at least 30 seconds).

, 2016 We present the first public implementation of antenna-based QCD initial- and final-state showers. The shower kernels are $2\to 3$ antenna functions, which capture not only the collinear dynamics but also the leading soft (coherent) singularities of QCD ...

Radio-Frequency-Controlled Urea Dosing for NH3-SCR Catalysts : NH3 Storage Influence to Catalyst Performance under Transient Conditions [PDF]
, 2017 Current developments in exhaust gas aftertreatment led to a huge mistrust in diesel driven passenger cars due to their NOx emissions being too high. The selective catalytic reduction (SCR) with ammonia (NH3) as reducing agent is the only approach today ...

Advanced Materials, Volume 38, Issue 1, 2 January 2026.Uncontrolled atomic migration during the pyrolysis of metal‐N‐C catalysts often leads to disordered coordination environments, active site loss, and poor oxygen electrocatalytic activities. Herein, a La‐mediated atomic migration strategy enables the fabrication of a well‐defined asymmetric heterostructure (LaN/LaFe‐NC) featuring a built‐in electric ...

Advanced Science, Volume 13, Issue 1, 5 January 2026.A sodium‐metalated, nitrogen‐rich carbon nitride (PH‐C3N5‐Na) is developed to generate solvated electrons (SEs) under visible‐light irradiation via a eutectic NaCl/LiCl molten salt‐assisted method. The in situ generated SEs drive a stepwise oxygen reduction via •O2−. Thus, an exceptional quantum efficiency of 54.4% (420 nm) is achieved.

Emission inventories and modeling requirements for the development of air quality plans. Application to Madrid (Spain) [PDF]
, 2014 Modeling is an essential tool for the development of atmospheric emission abatement measures and air quality plans. Most often these plans are related to urban environments with high emission density and population exposure. However, air quality modeling
