n‐Involved Optimization of Out‐of‐Plane Optoelectronic Performances in Nanoscale Ruddlesden–Popper Perovskite

open access: yesAdvanced Electronic Materials, 2023
Ruddlesden–Popper (RP) metal‐halide perovskites are attracting increasing attention due to their improved stability. The intercalated hydrophobic organic layer accounts for this improvement, however, it is detrimental to the out‐of‐plane optoelectronics.

Molecular engineering assembly of mesoporous carbon onto Ti3C2Tx MXene for enhanced lithium‐ion storage

open access: yesCarbon Neutralization, Volume 2, Issue 6, Page 678-688, November 2023., 2023
A molecular engineering assembly strategy has been proposed for assembling the N, P co‐doped mesoporous carbon onto 2D Ti3C2Tx nanosheets with the assistance of phytic acid. The delicate design endows the as‐made NPMC/Ti3C2Tx anode with an enhanced lithium‐ion storage performance. Abstract The rational construction of Ti3C2Tx MXene‐based composites has

N,N-Dibenzoylferrocenecarboxamide [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2011
In the title compound, [Fe(C(5)H(5))(C(20)H(14)NO(3))], the cyclo-penta-dienyl rings deviate by 9.3 (2)° from an eclipsed conformation, defined by C-Cg(1)-Cg(2)-C pseudo-torsion angles ranging from 8.8 (1) to 9.85 (1)°. The coordination at the N atom is slightly pyramidal, as indicated by the angular sum around it of 352.6°. The amide group is inclined

Adropin: An endocrine link between the biological clock and cholesterol homeostasis [PDF]

open access: yes, 2014
This article explores two translation models circling around the key issue “equivalence” in translation studies. They are the Jerome Model and the Horace Model. They differentiate from each other in the aspects of the translating priorities and purposes,
