Crystal structure of 4-[(adamantan-1-yl)amino]naphthalene-1,2-dione

Acta Crystallographica Section E: Crystallographic Communications, 2019
The title compound, C20H21NO2, an example of a stable 1,2-naphthoquinone, was determined by single-crystal X-ray diffraction analysis at 100 K. This structure illustrates steric buttressing of the adamantanyl group, forcing the N—H group into the ...

Investigation and Evaluation of Wax Deposition Treatment Methods in Large Natural Gas Plants

Energy Science &Engineering, EarlyView.
Problem: Wax blockage (Biphenyl, PAHs) in low‐temperature units crippled plant capacity. Solution: A novel Circulating Light Hydrocarbon Injection technology. Mechanism: Light hydrocarbons disrupt wax crystals via “like dissolves like” and are continuously recovered. Outcome: 1. Throughput dropped from 10 MMscmd to 3 MMscmd 2.

Hydrogel Adhesives for Gastrointestinal Perforation: Design Principles and Applications

Exploration, EarlyView.
There are few reviews on hydrogel adhesives that comprehensively highlight the design principles, factors affecting adhesion, and applications for gastrointestinal (GI) perforation repair. This review outlines the mainstream design approaches of hydrogel adhesives via covalent and noncovalent molecular interactions, illustrating the underlying adhesive

Keto-Adamantane-Based Macrocycle Crystalline Supramolecular Assemblies Showing Selective Vapochromism to Tetrahydrofuran

Molecules
Here, we report the synthesis of adamantane-based macrocycle 2 by combining adamantane building blocks with π-donor 1,3-dimethoxy-benzene units. An unpredictable keto-adamantane-based macrocycle 3 was obtained by the oxidation of 2 using DDQ as an ...

Unraveling Water Sorption in Single‐Crystal MOFs: Insights from Spectroscopy and Modeling on the Role of Structure, Composition, and Guest Molecules

Small, EarlyView.
Water scarcity drives the search for efficient atmospheric water harvesting (AWH) materials. This study explores the impact of metal substitution (Zr to Hf) and linker exchange (fumaric to trimesic acid) on the water sorption performance of MOF‐801 and MOF‐808.

Fluorinated copolymer resists for high‐resolution negative‐tone lithography: Preparation and patterning performance

Smart Molecules, EarlyView.
Electron‐beam induced C–F cleavage in –CF3 generates F−, which abstracts a proton to form the acid that catalyzes tBMA deprotection during post‐exposure baking. This self‐sensitization mechanism enables the precise formation of high‐resolution negative‐tone patterns with enhanced sensitivity and resolution.
