Angraecum sesquipedale, also known as Darwin's orchid, possesses an exceptionally long nectar spur. Charles Darwin predicted the orchid to be pollinated by a hawkmoth with a correspondingly long proboscis, later identified as Xanthopan praedicta. In this plant-pollinator interaction, the A.

Herein, NH-MIL-125(Ti)/TiO Z-scheme heterojunction with intimate interfacial contact was synthesized for synchronous removal of pollutant in coexisting Cr(VI)/dyes system under simulated solar irradiation. Structural and optical investigations indicated that a well-defined interface was formed by establishing a Ti-N-C bond, facilitating the spatial separation of the photoexcited carriers of the Z-scheme heterojunction.

The resulting CDs emit ultraviolet (UV) PL centered at 345 nm with a full width at half maximum (FWHM) of 54 nm, with blue-shift of over 100 nm and FWHM narrowed by nearly half in comparison with that of the CDs prepared by using the traditional solvothermal method.

Here, we show that in LLC-PK1 cells, APC and KIF2A, an MT depolymerase, form a complex clustering at the cell edge and destabilize MTs at the MT plus ends. Further biochemical characterization and mutational analysis reveal key residues for the APC-KIF2A interaction.

Herein, a proof-of-concept hybridized local and charge transfer (HLCT) molecule, named ICz-BO, is prepared and characterized, in which both multiresonant (MR) skeletons are integrated via conjugation connection. A slightly distorted structure and weak intramolecular charge transfer (CT) interaction between two MR subunits lead to a high-lying reverse intersystem crossing (h-RISC) channel of T→S, also evidenced by both experimental and calculated results.

However, due to the extremely high homology among the three PIM isoforms (PIM1, PIM2, PIM3) and the limited availability of existing bioactivity data, screening and designing selective PIM inhibitors remain a daunting challenge. To address this issue, this study constructed a multitask regression model that can simultaneously predict the half-maximal inhibitory concentration (IC values).

A high-capacity and rate capability anode material is highly desired to improve the export performance of aqueous alkaline batteries (AABs). Due to the 3-electrons redox chemistry within a wide negative potential range, bismuth (Bi) based compounds are promising candidates as anode materials in AABs. A hybrid composed of different Bi-based compounds is envisioned to further reinforce the faradaic activity and affinity for electrolyte ions, thereby maximizing the charge storage capacity.

While immune checkpoint inhibitors (ICIs) have transformed treatment for advanced NSCLC, the role of bone metastasis in modulating ICI efficacy remains unclear. Bone metastasis, occurring in 30-40% of advanced NSCLC cases, is associated with worse outcomes.

Soft confinement is realized in binary blends composed of AB diblock copolymers and C homopolymers, where the copolymers self-assemble to form a droplet embedded in a homopolymer matrix. The phase behavior of the confined block copolymers is regulated by the degree of confinement and the selectivity of the homopolymers, resulting in a rich variety of novel structures.
