Changes in speciated PM2.5 concentrations in Fresno, California, due to NOx reductions and variations in diurnal emission profiles by day of week

open access: yesElementa: Science of the Anthropocene, 2019
The San Joaquin Valley in California suffers from poor air quality due to a combination of local emissions and weak ventilation. Over the course of decades, there has been a concerted effort to control emissions from vehicles as well as from residential ...

The preservation of atmospheric nitrate in snow at Summit, Greenland [PDF]

open access: yes, 2013
There is great interest in using nitrate NO3 isotopic composition in ice cores to track the history of precursor nitrogen oxides (NOx = NO + NO2) in the atmosphere.

Pearl‐Like Bioinspired Coating Enables Regulation of Mg Degradation for Osteoporotic Bone Repair

open access: yesAdvanced Science, EarlyView.
In this study, inspired by pearl architecture, we developed a layered Ca–P “brick” and Fn‐mimetic peptide “mortar” coating on Mg alloys. The Ca–P layer moderates corrosion and offers mineral cues, while the peptide enhances adhesion and regulates immune‐vascular responses.

Molecular Electrocatalyst Enables Direct Electrochemical Capture and Conversion of CO2 up to Atmospheric Concentration

open access: yesAngewandte Chemie, EarlyView.
A molecular manganese electrocatalyst enables the direct electrochemical capture and conversion of dilute CO2 (1% – 0.2%) to CO with nearly unit Faradaic efficiency, achieving high efficiency even at atmospheric concentrations (420 ppm). By bypassing energy‐intensive pre‐concentration steps, this integrated approach highlights a sustainable pathway for

Low NOx ammonia / methane combustion with highly preheated air in a furnace

open access: yesJournal of Thermal Science and Technology
In this study, attempts have been made to utilize ammonia in the industrial heating field, in which highly preheated air around 1000°C is used under high temperature atmosphere inside the furnace 1200°C. The high temperature inlet air and atmosphere are

Interplay between BMPs and Reactive Oxygen Species in Cell Signaling and Pathology

open access: yesBiomolecules, 2019
The integration of cell extrinsic and intrinsic signals is required to maintain appropriate cell physiology and homeostasis. Bone morphogenetic proteins (BMPs) are cytokines that belong to the transforming growth factor-β (TGF-β) superfamily ...

Nox Response to Injury [PDF]

open access: yesArteriosclerosis, Thrombosis, and Vascular Biology, 2002
Szocs and colleagues,1 in this issue of Arteriosclerosis, Thrombosis and Vascular Biology , have added to our understanding of the role of NAD(P)H oxidase and reactive oxygen species in vascular injury. The study was undertaken by using the rat carotid artery balloon injury model, a well-characterized model of neointimal formation.

Ni Single‐Atom Modulation of Ti‐O Covalency Boosts Ammonia Oxidation Electrocatalysis

open access: yesAdvanced Science, EarlyView.
A Ni single‐atom‐induced enhancement of Ti‐O covalency in Ni SAC@TiO2 generates abundant active sites and promotes selective NHx‐NHy mediated N2 evolution while suppressing poisonous NOx formation, achieving nearly doubled AOR activity with excellent durability.

Electrochemical Nitrate Reduction Reaction to Ammonia at Industrial‐Level Current Densities

open access: yesAdvanced Science, EarlyView.
This review starts from the mechanism and theoretical basis of electrochemical nitrate reduction reaction (NO3−RR), and systematically summarizes and discusses the design strategies of industrial‐level current density catalysts. In addition, the progress of industrial‐level NO3−RR‐based electrolyzers, including flow reactor and membrane electrode ...

Noxed - A NOX Engine World Editor

open access: yes, 2016
Noxed is a 2D level editor built for – and with – the NOX Engine. It leverages the JSON file format of actors and world files to construct a world file that can be understood by the built-in means of world loading within the NOX Engine. It eases the process of creating levels for the games without the tedium of manual JSON addition or reliance on ...
