The Real Structure of Intergrown ZSM‐5/ZSM‐11 Industrial Zeolite Catalysts

Small Structures
In some industrial‐scale reactions, an intergrowth of ZSM‐5 and ZSM‐11 aluminosilicate zeolites is the preferred catalyst. These structures each have two intersecting channel systems with 10‐ring windows, defined by 10 oxygen atoms. The channels are both

Soft tissue abnormalities in the congenital limb malformation radial dysplasia (RD): Their clinical impact and treatment significance

Journal of Anatomy, EarlyView.
We review the characteristic changes to the limb soft tissue and neurovascular abnormalities that have been described in the congenital limb birth defect, Radial Dysplasia. These include consistent changes in muscle anatomy or absence of specific muscles, persistent median arteries and absent radial arteries and consistent alterations in neural ...

Transitioning of the Chemical Industry Toward a Net‐Zero Carbon Dioxide Emission Path

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
One way to reduce the greenhouse gas footprint of the chemical industry to almost zero would be the production of the platform molecules C1‐compounds, olefins, aromatics, and ammonia by non‐fossil pathways. The rest of the chemical production chains could be essentially left unchanged, provided the process energy input is renewable.

Synergistic effects of Ni and CeO2 on ZSM-5 for enhancement of CO2 methanation at low temperatures

Sustainable Chemistry for Climate Action
Methanation offers a potential option for converting CO2 to green synthetic fuels, providing a solution for reducing carbon emissions. Nickel-based catalysts, promoted with CeO2 and supported on zeolite ZSM-5, were synthesized for CO2 methanation using ...

The Effect of Mesoporous H-ZSM-5 Crystallinity as a CaO Support on the Transesterification of Used Cooking Oil

Bulletin of Chemical Reaction Engineering & Catalysis, 2017
Transesterification of used cooking oil was carried out over calcium oxide supported on mesoporous H-ZSM-5 prepared from kaolin as solid base catalysts. Solid basic catalysts investigated in this study were characterized by XRD, FTIR spectroscopy, and N2

Sleep and Maladaptive Personality Traits: A Twin Study

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep is essential for human functioning, but little attention has been paid to the interplay between sleep and maladaptive personality traits. We examined genetic and environmental associations between sleep and four maladaptive domains (MDs)—Negative Affectivity, Detachment, Disinhibition, and Psychoticism—within the framework of the DSM‐5 ...

Variable Flood Discharge Constrains Autochthonous Organic Carbon Preservation in Deltas: Insights From Physical Experiments

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Many global and regional climate models predict shifts in the frequency and magnitude of precipitation events. It is unclear how this transition will influence delta and wetland development. We address this knowledge gap via two reduced‐scale physical delta experiments: one with constant discharge and the other with variable discharge.
