论文题目:Macrocyclic Polyradicaloids with Unusual Super-ring Structure and Global Aromaticity

论文摘要:Organic opto-electronic and magnetic materials play an important role in future affordable electronics and clean energy, and aromaticity is one of the most important concepts that determine their physical and material properties. Over the past nine decades, Hückel's rule and Baird's rule have been developed to describe the (anti)aromaticity of monocyclic π-conjugated molecules. For polycyclic π-conjugated systems, localized aromaticity usually dominates, and there is almost no report of global aromaticity for benzenoid polycyclic hydrocarbons. In this work, we experimentally obtained two hydrocarbon-based macrocyclic polyradicaloids, which show a long-sought-after annulene-within-an-annulene super-ring structure and very unusual global aromaticity. Both Hückel's rule and Baird's rule can be followed for these polyradicaloids. Our study gives some new insight into the unique global aromaticity in polycyclic π-conjugated molecules.

论文题目:Remarkably enhanced water splitting activity of nickel foam due to simple immersion in a ferric nitrate solution

论文摘要:The development of a facile method to construct a high-performance electrode is of paramount importance to the application of alkaline water electrolysis. Here, we report that the activity of nickel foam (NF) towards the oxygen evolution reaction (OER) can be enhanced remarkably through simple immersion in a ferric nitrate (Fe(NO3)3) solution at room temperature. During this immersion process, the oxidation of the NF surface by NO3− ions increases the near-surface concentrations of OH− and Ni2+, which results in the in situ deposition of a highly active amorphous Ni-Fe hydroxide (a-NiFeOxHy) layer. Specifically, the OER overpotential of the NF electrode decreases from 371 mV (bare NF) to 270 mV (@10 mA·cm−2 in 0.1 M KOH) after immersion in a 20 mM Fe(NO3)3 solution for just 1 min. A longer immersion time results in further increased OER activity (196 mV@10 mA·cm−2 in 1 M KOH). The overall water splitting properties of the a-NiFeOxHy@NF electrode were evaluated using a two-electrode configuration. It is worth noting that the current density can reach 25 mA·cm−2 in 6 M KOH at an applied voltage of 1.5 V at room temperature.

论文题目:Engineering blood exosomes for tumor-targeting efficient gene/chemo combination therapy

论文摘要:

Rationale: Developing an effective nanoplatform to realize 'multi-in-one' is essential to broaden the therapeutic potential of combination therapy. Exosomes are ideal candidates since their intrinsic abilities of integrating multiple contents and functions. However, only limited efforts have been devoted to engineering exosomes to integrate the needed properties, also considering the safety and yield, for tumor-targeted and efficient gene/chemo combination therapy.

Methods: Herein, by manipulating the exosome membrane, blood exosomes with high abundance and safety are engineered as a versatile combinatorial delivery system, where the doxorubicin (Dox) and cholesterol-modified miRNA21 inhibitor (miR-21i) are co-embedded into the lipid bilayer of exosomes, and the magnetic molecules and endosomolytic peptides L17E are bind to the exosome membrane through ligand-receptor coupling and electrostatic interactions, respectively.

Results: It is proved that such engineering strategy not only preserves their intrinsic features, but also readily integrates multiple properties of tumor targeting, efficient transfection and gene/chemo combination therapy into blood exosomes. The lipid bilayer structure of exosomes allows them to co-load Dox and miR-21i with high-payloads. Moreover, profiting from the integration of magnetic molecules and L17E peptides, the engineered exosomes exhibit an enhanced tumor accumulation and an improved endosome escape ability, thereby specifically and efficiently delivering encapsulated cargos to tumor cells. As a result, a remarkable inhibition of tumor growth is observed in the tumor-bearing mice, and without noticeable side effects.

Conclusions: This study demonstrates the potential of engineered blood exosomes as feasible co-delivery nanosystem for tumor-targeted and efficient combination therapy. Further development by replacing the drugs combined regimens can potentially make this engineered exosome become a general platform for the design of safe and effective combination therapy modality.

论文摘要:In article number 2001388, Yupeng Zhang, Baohua Jia, Qiaoliang Bao, and co‐workers develop flat lenses based on 2D perovskite nanosheets using a cost‐effective mask‐free femtosecond direct laser writing system. The tunable material property affords effective manipulation of both amplitude and phase of the incident light, which is focused into a subwavelength 3D spot with a resolution in the range of 0.5‐.9λ.

论文摘要:In article number 1908176, Joshua D. Caldwell, Alexey Y. Nikitin, Pablo Alonso‐González, and co‐workers extract the IR permittivity of the biaxial crystal α‐MoO3 by correlative far‐ and near‐field measurements, using FTIR reflectance spectroscopy and s‐SNOM polariton interferometry, thus providing both an accurate permittivity model and a novel approach to extracting dielectric functions of nanomaterials. Moreover, through density functional theory, insights into the vibrational states dictating such permittivity are revealed.
