Crystal structure of μ-peroxido-κ4O1,O2:O1′,O2′-bis[(nitrato-κO)(2,2′:6′,2′′-terpyridine-κ3N,N′,N′′)dioxidouranium(VI)]

Acta Crystallographica Section E: Crystallographic Communications, 2015
In the title dimeric complex, [{UO2(NO3)(C15H11N3)}2O2], a peroxide ion bridges the two uranyl(VI) [O=U=O]2+ ions. The O—O bond length of the peroxide is 1.485 (6) Å and the mid-point of this bond is located at the inversion centre of the dimer.

Direct Ink Writing of Conductive Hydrogels

Advanced Functional Materials, EarlyView.
This review examines the use of direct ink writing (DIW) for fabricating conductive hydrogels with customizable 3D structures. It outlines the rheological requirements for successful DIW, followed by an exploration of the materials and ink formulations used to impart electronic and/or ionic conductivity to hydrogels while maintaining printability ...

Recent Advances in Enzyme‐based Biofuel Cells Using Glucose Fuel: Achieving High Power Output and Enhanced Operational Stability

Advanced Functional Materials, EarlyView.
Effective electron transfer and stable enzyme immobilization, both between enzymes and host electrodes as well as between adjacent enzymes, are crucial for optimizing the biofuel cell (BFC) performance. Recently, efforts have focused on integrating these strategies with porous host electrodes.

Dimethylenediol peroxide (diformal peroxide hydrate) [PDF]

Proceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1914
The conditions of the co-existence of hydrogen dioxide and formaldehyde, and the nature of their interaction, are of special interest in connection with the theories which have been advanced to account for the photosynthesis of carbohydrates in plants.

Small RNA ArcZ Regulates Oxidative Stress Response Genes and Regulons in Erwinia amylovora

Frontiers in Microbiology, 2019
Erwinia amylovora, causative agent of fire blight disease of apple and pear trees, has evolved to use small RNAs for post-transcriptional regulation of virulence traits important for disease development.

Time‐Controlled Dual Targeting to Program Systemic and Intercellular Transfer of Therapeutic Effects

Advanced Functional Materials, EarlyView.
Aspirin‐liposomes loaded onto monocytes enable inflammation‐triggered targeting and efficient hand‐over of aspirin to inflamed cells. Monocytes uptake a significant portion of aspirin‐liposomes, prolonging therapeutic action. This approach enhances anti‐inflammatory effects through intercellular transfer, demonstrating a translational strategy for ...

Instability of Amorphous Oxide Semiconductors via Carrier-Mediated Structural Transition between Disorder and Peroxide State [PDF]

arXiv, 2011
The excited holes occupying the valence band tail states in amorphous oxide semiconductors are found to induce formation of meta-stable O$_2^{2-}$ peroxide defects. The valence band tail states are at least partly characterized by the O-O pp{\sigma}* molecular orbital, and the localized-hole-mediated lattice instability results in the formation of the ...

Effects of hole self-trapping by polarons on transport and negative bias illumination stress in amorphous-IGZO [PDF]

, 2017
The effects of hole injection in amorphous-IGZO is analyzed by means of first-principles calculations. The injection of holes in the valence band tail states leads to their capture as a polaron, with high self-trapping energies (from 0.44 to 1.15 eV). Once formed, they mediate the formation of peroxides and remain localized close to the hole injection ...
