Partially Biobased Polyurethanes With Reversibly Crosslinkable Furan Units Toward Recyclable Thermosetting Textile Fibres

open access: yesChemistry – A European Journal, EarlyView.
A molecular design strategy combines lignin‐derived aromatic units, sugar‐derived furan groups, and flexible glycol segments to create wet‐spinnable polyurethanes. Thermally reversible Diels–Alder crosslinking chemistry enables formation of crosslinked thermosetting fibers, repeated de‐crosslinking/re‐crosslinking cycles, and tunable fiber properties ...

Complexes of N-thiophosphorylated thioureas and triphenylphosphine with CuI [PDF]

open access: yes, 2003
The complexes (PriO)2P(S)NHC(S)R (R = NEt 2, NHPh), [(PriO)2P(S)NHC(S)] 2-1,10-diaza-18-crown-6 have been obtained by the metathesis reaction of potassium salts of corresponding thiophosphorylated thioureas with (PPh3)2CuNO3; the crystal structure of (Ph

Regioisomerism Rewires Optical and Ion Recognition Properties in Azulenylsumanenes—Curved Non‐Alternant π‐Systems

open access: yesChemistry – A European Journal, EarlyView.
Regioisomerism rewires orbital topology and electronic polarity in curved non‐alternant π‐systems, switching both optical response and alkali metal ion recognition from Na+ to Rb+ selectivity. ABSTRACT Herein, we explore the fundamental concept of combining the molecular curvature of a molecular fragment of buckminsterfullerene with the pronounced ...

Zebrafish inversin mutants develop scoliosis in the absence of laterality defects

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Human mutations in INVERSIN are associated with nephronophthisis, variable penetrance of situs inversus and congenital heart disease. Inversin has been shown to localize to cilia and many of the patient phenotypes are attributed to disrupted cilia function.

Zebrafish ventral gastrula fate map reveals neural crest progenitor domain

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Fate maps relate progenitor cell positions to later fates and locations of their progeny, revealing early embryonic organization. Previous zebrafish fate maps identified the origin of germ layers and derivative cell fates, but ventral gastrula progenitor domains were not fully resolved. In particular, the neural crest, a multipotent

Achievement of Transition Metal Chalcogenides/Oxides in Hydrogen Production by Seawater Electrolysis

open access: yesEcoEnergy, EarlyView.
Transition metal chalcogenides (TMCs)/oxides have shown great application potential in seawater splitting for hydrogen generation due to their adjustable electronic properties, abundant active sites, and excellent catalytic performance. ABSTRACT Under the impetus of global “dual carbon” goals, green hydrogen has become a key component of the future ...

Competitive Cationic Adsorption‐Driven Dynamic Electrostatic Shielding Enables Ultra‐Stable Zn Metal Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates the dynamic electrostatic shielding effect driven by competitive cation adsorption and its role in stabilizing zinc anodes for aqueous zinc metal batteries. The preferential adsorption of R+ cations, particularly K+, effectively rearranges the inner Helmholtz layer, modulates the electric field distribution, and weakens zinc ...

Unlocking Ammonium‐Ion Storage Capability of MoS2 via Synergistic Molecular Engineering Strategies

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The multiple molecular engineering strategies are simultaneously adopted to endow MoS2 with expanded interlayer distance, abundant active sites and strengthened structural stability. Benefitting from the synergistic effects of phase engineering, doping engineering, and structural engineering strategies, the proposed 1T‐O‐MoS2@HCSs exhibits ...

Enhanced Electron‐Capturing by Single‐Atomic Iron on Pyridinic N‐Deficient Carbon Drives Self‐Oxidative Degradation of Pollutants

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Pyrolysis of FeOx/g‐C3N4 and ZIF‐8 is performed to introduce Fe single atom and pyridinic nitrogen vacancies onto N‐doped carbon. This modification enables the materials to efficiently extract electrons from ciprofloxacin (CIP) and activate dissolved oxygen. 100% of CIP was degraded within 1 min without adding any oxidant.
