On the use of an explicit chemical mechanism to dissect peroxy acetyl nitrate formation. [PDF]

, 2014
Peroxy acetyl nitrate (PAN) is a key component of photochemical smog and plays an important role in atmospheric chemistry. Though it has been known that PAN is produced via reactions of nitrogen oxides (NOx) with some volatile organic compounds (VOCs ...

C16 Phase High Entropy Borides With High Magnetic Anisotropy

Advanced Materials, EarlyView.
Rare‐earth‐free C16‐phase high entropy boride thin films exhibit enhanced magnetic anisotropy with coercivities surpassing their binary and ternary counterparts. Combinatorial synthesis of (Fe‐Co‐Ni‐Mn)2B films combined with density functional theory enables mapping of the magnetic properties across the composition space, revealing high entropy ...

Biogenic Silica from Rice Husk Ash - Sustainable Sources for the Synthesis of Value Added Silica

Chemical Engineering Transactions, 2014
Ordered mesoporous silica with two dimensional MCM-41 or three dimensional MCM-48 pore structure are prepared via pseudomorphic transformation. Rice husk ash (RHA) with high purity was used as silica source for the first time.

Eutectozymes as Soft Hybrid Materials for Advanced Biocatalysis

Advanced Materials, EarlyView.
Eutectozymes are sustainable hybrid materials that embed a GOx–HRP cascade within hydrophobic eutectogels featuring a dual supramolecular–covalent network. This architecture preserves native enzyme structure and stability, enables efficient heterogeneous biocatalysis in aqueous media, and positions eutectogels as robust platforms for next‐generation ...

Tailor-Made Nanostructured Ion Selective MCM-48 Membranes [PDF]

, 2003
Mesoporous templated MCM-48 silica was prepared using a C16 surfactant as template. The MCM-48 powders and thin films were characterized by different techniques. Two types of porous supports were used, namely macroporous ¿-alumina and silicon microsieves.

Engineering Free Volume within Frontal Ring‐Opening Metathesis Polymerization via Pendant Plasticization

Advanced Materials, EarlyView.
Norbornene‐based copolymers with tunable n‐alkyl pendant length provide control over matrix free volume, enabling elastomeric materials via frontal ring‐opening metathesis polymerization (FROMP). ABSTRACT Frontal ring‐opening metathesis polymerization (FROMP) enables rapid, energy‐efficient access to high‐performance thermosets and thermoplastics, but ...

Galactic Archaeology with CoRoT and APOGEE: Creating mock observations from a chemodynamical model [PDF]

, 2016
In a companion paper, we have presented the combined asteroseismic-spectroscopic dataset obtained from CoRoT lightcurves and APOGEE infra-red spectra for 678 solar-like oscillating red giants in two fields of the Galactic disc (CoRoGEE). We have measured
