Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies

open access: yesAdvanced Engineering Materials, EarlyView.
Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...

Transition Metal‐Driven Selectivity in Direct C−H Arylation of Imidazo[2,1‐b]Thiazole

open access: yesChemistryOpen
A selective direct arylation of the different Csp2‐H bonds of imidazo[2,1‐b]thiazole with (hetero) aryl halides can be achieved simply by switching from a palladium catalyst system to the use of stoichiometric amounts of copper. The observed selectivity,

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

The versatile and strategic O-carbamate directed metalation group in the synthesis of aromatic molecules

open access: yes
The aryl O-carbamate (ArOAm) group is among the strongest of the directed metalation groups (DMGs) in directed ortho metalation (DoM) chemistry, especially in the form Ar-OCONEt$_2$.

Highly-selective metalation of porphyrin enabled by distinct aromatic ring-fused structures [PDF]

open access: yes
Metalation is an effective strategy for tuning the optical, magnetic, and other physical properties of porphyrins, which play an important role in material synthesis and biological activities. Multiple aromatic ring-fused structures (ARFSs) can be formed

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

open access: yesAdvanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Postsynthetic Rearrangement/Metalation as a Route to Bimetallic Uranyl Coordination Polymers: Syntheses, Structures, and Luminescence

open access: yes, 2016
Postsynthetic metalation of a uranyl isonicotinate starting material (UICP) with Ag­(I) and Cu­(II) under hydrothermal conditions has yielded two new coordination polymers: (UO2)­(OH)­(C6H4NO2)2Ag (1) and (UO2)2(O)­(OH)­(C6H4NO2)2Cu­(OH2)Cl (2).
