Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

Advanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

Demonstration of an All‐Optical AND Gate Mediated by Photochromic Molecules

Advanced Functional Materials, EarlyView.
A logic AND gate that runs on photons is demonstrated. It relies on two spatially separated photochromic molecules that work in tandem. Abstract The realization of a photonic logic AND gate, i.e. a logic AND gate that runs on photons rather than electrons, and where all steps are controlled by light, is demonstrated. In a proof‐of‐principle experiment,

Selective Benzene Capture by Metal‐Organic Frameworks

Advanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) hold significant potential for capturing benzene from air emissions and hydrocarbon mixtures in liquid phases. This capability stems from their precisely engineered structures, versatile chemistries, and diverse binding interactions.

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Factors Affecting Vehicular Emissions and Emission Models

ICTE 2013, 2013
Because there is no second opinion about the fact that traffic-induced emissions are the major air pollutants, considerable attention is required to determine and quantify the factors that are responsible for these emissions. The following factors directly or indirectly are known to affect the emission levels: vehicle type, fuel type, driving activity,

Sugarcane burning emissions: Characterization and emission factors

Atmospheric Environment, 2018
Abstract Open burning of sugarcane (Saccharum officinarum) has a large impact in regional atmospheric pollution and global climatic change. In this research, pollutant emissions from sugarcane residues burning were measured in order to determine the emission factors (EFs) of elemental carbon (EC), organic carbon (OC), 18 polycyclic aromatic ...

Evaluation of Emissions and Emission Factors

1997
The EURAD model has been applied to a summer smog episode in July/August 1990. The transport, chemical transformation and deposition of atmospheric constituents for that episode have been calculated. Emission data estimated by GENEMIS have been used to replace the standard scheme of the EURAD emission model EEM which is based mainly on annual EMEP data.
