Tuning Pore Geometry of Zirconium Metal–Organic Frameworks via Bent Ligands for Enhanced Sulfide Oxidation Catalysis

open access: yesAngewandte Chemie International Edition, EarlyView.
Engineering pore geometry through ligand conformational bending enhances active‐site accessibility and mass transport in Zr‐MOFs, leading to superior catalytic sulfide oxidation. ABSTRACT Pore engineering represents a powerful strategy to tailor the physicochemical properties of metal–organic frameworks (MOFs), yet the structure‐activity relationship ...

Comparative Performance of Poly(Vinyl Alcohol)/Chitosan Hydrogels Reinforced With Kraft Lignin and Kraft Lignin Nanoparticles

open access: yesJournal of Applied Polymer Science, EarlyView.
The use of kraft lignin and kraft lignin nanoparticles in poly(vinyl alcohol)/chitosan hydrogels was comprehensively compared. The results showed that a higher loading of lignin nanoparticles than bulk kraft lignin could be incorporated while maintaining favorable hydrogel properties, leading to improved overall performance. ABSTRACT The development of

Diol Chain‐Length Effects in Adipate and Succinate Polyesters for Thermoplastic Polyurethanes

open access: yesJournal of Applied Polymer Science, EarlyView.
This study examines 20 aliphatic polyesters as soft segments for thermoplastic polyurethanes (TPU), synthesized from adipic or succinic acid and diols (C2, C3, C4, C5, and C6). A pronounced odd‐even effect shows that even diols crystallize, while odd diols remain amorphous.

Study on the crystallization kinetics of Ni-Mn-Sn-Fe alloy thin films

open access: yesMaterials Research Express
This study examines the crystallization kinetics of Ni _50−x Mn _39 Sn _11 Fe _x (x = 0, 0.5, 2, 4 at.%) amorphous thin films prepared by DC magnetron sputtering. SEM and XRD confirm their amorphous structure.

Development and application of a mechanistic model for protein A resolution of a bispecific antibody for process characterization and optimization

open access: yesBiotechnology Progress, EarlyView.
Abstract Regeneron's bispecific technology, based on a fully human IgG antibody construct, consists of two distinct heavy chains and a common light chain co‐expressed in a single cell. The co‐expression of the two distinct heavy chains, one of which contains a dipeptide substitution that ablates Protein A binding, leads to the formation of three ...

Non-Isothermal Crystallization of Polymers

open access: yes, 2013
Studie kinetiky krystalizace jsou omezené idealizovanými podmínkami, kde je například teplota konstantní (izotermní způsob krystalizace). Ve skutečnosti se však stavové vnější podmínky souvisle mění, což dělá průběh krystalizace závislým na okamžitých ...

Recent Advances in Ionizing Radiation as a Nonequilibrium Chemical Field for Catalysis

open access: yesCarbon and Hydrogen, EarlyView.
Ionizing radiation acts as a nonequilibrium chemical field that generates reactive species and structural perturbations. These radiation‐induced effects bridge catalytic material construction, including metal loading, framework evolution, defect engineering, and carbon‐network reorganization, with selective transformations such as oxidation, reduction,
