Engineering Polar Nanoregions in COFs via Controlled Symmetry Breaking Toward Piezocatalysis

open access: yesAngewandte Chemie, EarlyView.
Polar nanoregions (PNRs) are engineered within covalent organic frameworks via asymmetric grafting of highly polar polyfluoroalkyl chains, which enables controlled symmetry breaking. These randomly oriented artificial PNRs dynamically respond to mechanical stimuli and impart relaxation behavior to the COFs (TFB‐TAPT‐FA).

Linker‐Locking Strategy for the Rigidification of Flexible Metal–Organic Framework: Structural Stabilization and Controlled ESIPT for H2O/D2O Sensing

open access: yesAdvanced Science, EarlyView.
A linker‐locking strategy rigidifies the flexible metal–organic framework (MOF) MIL‐53‐(OH)2 via the cooperative encapsulation of ligands and structural water. This network significantly enhances the framework's aqueous stability. Crucially, rigidification suppresses enol emission to yield a single keto tautomer state with an extended lifetime ...

Moisture sorption isotherms and isosteric heat determination in Chilean papaya (Vasconcellea pubescens)

open access: yesQuímica Nova, 2008
The moisture sorption isotherms of Chilean papaya were determined at 5, 20, and 45 ºC, over a relative humidity range of 10-95%. The GAB, BET, Oswin, Halsey, Henderson, Smith, Caurie and Iglesias-Chirife models were applied to the sorption experimental ...

Measurement and modeling of water sorption isotherm for salt‐laden autoclaved aerated concrete

open access: yesJapan Architectural Review, 2018
The authors reported on the measurement of water sorption isotherms for autoclaved aerated concrete, commonly called “autoclaved lightweight concrete” in Japan, containing aqueous salt (sodium chloride or magnesium chloride) solutions in concentrations ...

Intrinsic Superprotonic Conduction in Metal‐Free Hydrogen‐Bonded Organic–Inorganic Frameworks

open access: yesAdvanced Science, EarlyView.
A simple hybridization strategy yields a suite of metal‐free hydrogen‐bonded organic‐inorganic frameworks (HOIFs) with dense, uninterrupted hydrogen‐bonded networks that possess intrinsically high superprotonic conductivity, establishing a versatile and scalable platform for high‐performance solid‐state proton conductors.

Rare‐Earth Multivariate Metal–Organic Frameworks: Cationic Radius Biased Compositional Control and Property Tuning

open access: yesAngewandte Chemie, EarlyView.
A family of multivariate metal–organic frameworks, UoB‐116(Ln), can be prepared using up to 16 different metals, revealing the ability to tune properties through compositional control. ABSTRACT The synthesis of a multivariate metal–organic framework (MTV‐MOF) family, [Ln(DNNDI)1.5]n (UoB‐116), is reported (DNNDI: N,N'‐bis(dinicotinate)‐1,4,5,8 ...

Engineering an Artificial Metalloenzyme for Efficient Photo‐Enzymatic CO2 Conversion

open access: yesAdvanced Science, EarlyView.
We built a light‐driven artificial metalloenzyme by covalently conjugating formate dehydrogenase (FDH) with a tailored rhodium complex (Rh‐L6) to overcome spatial‐separation‐limited electron transfer. This integration boosts NADH regeneration and CO2 conversion, giving 2.31‐fold higher formate yield than physical mixtures, due to a narrowed bandgap and

ZINC AND COPPER SORPTION IN THE AFFECTED SOILS OF THE CHEREPOVETS METALLURGICAL COMPLEX

open access: yesБюллетень Почвенного института им. В.В. Докучаева, 2010
The laws of zinc and copper absorption by agrarian and carbonate soils in the area of Cherepovets Steel Mill are described. Sorption isotherms demonstrate high affinity of PPK of the studied soils to zinc and copper.

Regeneration‐Optimized Chemisorbents: Evaluating Hybrid Coordination Networks for Atmospheric Water Harvesting

open access: yesAngewandte Chemie, EarlyView.
Atmospheric water harvesting (AWH) under arid conditions requires desiccants that load water below 30% RH and regenerate below 60°C, a performance regime traditionally limited to physisorbents. Here, we show that the inherent hydrolytic instability of M′FSIX‐25‐M coordination networks enable regeneration‐optimized chemisorbents (ROCs) with projected ...
