Staudinger Reaction-Responsive Coacervates for Cytosolic Antibody Delivery and TRIM21-Mediated Protein Degradation.

A low-molecular-weight compound whose structure strikes a fine balance between hydrophobicity and hydrophilicity may form coacervates via liquid-liquid phase separation in an aqueous solution. These coacervates may encapsulate and convoy proteins across the plasma membrane into the cell. However, releasing the cargo from the vehicle to the cytosol is challenging.

Copper-Catalysed Electrochemical CO2 Methanation via the Alloying of Single Cobalt Atoms.

The electrochemical reduction of carbon dioxide (CO2) to methane (CH4) presents a promising solution for mitigating CO2 emissions while producing valuable chemical feedstocks. Although single-atom catalysts have shown potential in selectively converting CO2 to CH4, their limited active sites often hinder the realization of high current densities, posing a selectivity-activity dilemma. In this study, we developed a single-atom cobalt (Co) doped copper catalyst (Co1Cu) that achieved a CH4 Faradaic efficiency exceeding 60% with a partial current density of -482.

Preparation of anti-shrinkage branched poly (butylene succinate-co-butylene terephthalate)/cellulose nanocrystal foam with excellent degradability and thermal insulation.

Silver-Catalyzed Cascade Radical Isonitrile Insertion/Defluorinative Cyclization: Direct Synthesis of 4-CFH-2-Phosphinoyl-quinolines.

A novel silver-catalyzed cascade radical isonitrile insertion and defluorinative cyclization have been developed to synthesize CFH- and phosphinoyl-containing quinolines from -isocyanyl α-trifluoromethylstyrenes. The reaction proceeded under redox-neutral conditions and allowed the construction of a highly attractive quinoline ring system, with the simultaneous formation of the CFH group and introduction of various phosphinoyl groups in a single transformation, showing operational simplicity, a wide substrate scope, good tolerance for functional groups, and remarkable atom-/stepeconomy. Mechanistic studies indicated that the reaction is likely to involve the participation of P-centered radicals and key carbanion intermediates.

Intramolecular Cyclization and Energetic Group Modifications for Thermally Stable and Low-Sensitivity Monocyclic Dinitromethyl Zwitterionic Pyrazoles.

Zwitterionic energetic materials offer a unique combination of high performance and stability, yet their synthesis and stability enhancement remain key challenges. In this study, we report the synthesis of a highly stable (dinitromethyl-functionalized zwitterionic compound, 1-(amino(iminio)methyl)-4,5-dihydro-1H-pyrazol-5-yl)dinitromethanide (), with a thermal decomposition temperature of 215 °C, surpassing that of most previously reported energetic monocyclic zwitterions ( < 150 °C). This compound was synthesized via intramolecular cyclization of a trinitromethyl-functionalized hydrazone precursor.

Pick-and-Place Transfer of Arbitrary-Metal Electrodes for van der Waals Device Fabrication.

Van der Waals electrode integration is a promising strategy to create nearly perfect interfaces between metals and 2D materials, with advantages such as eliminating Fermi-level pinning and reducing contact resistance. However, the lack of a simple, generalizable pick-and-place transfer technology has greatly hampered the wide use of this technique. We demonstrate the pick-and-place transfer of prefabricated electrodes from reusable polished hydrogenated diamond substrates without the use of any sacrificial layers due to the inherent low-energy and dangling-bond-free nature of the hydrogenated diamond surface.

Nineteen real driving cycles were generated using widely employed K-means and PCA algorithms.

Self-Assembling of Multilayered Polymorphs with Ion Beams.

Polymorphism determines significant variations in materials' properties by lattice symmetry variation. If they are stacked together into multilayers, polymorphs may work as an alternative approach to the sequential deposition of layers with different chemical compositions. However, selective polymorph crystallization during conventional thin film synthesis is not trivial; changes of temperature or pressure when switching from one polymorph to another during synthesis may cause degradation of the structural quality.

The explosion of Internet-of-Thing enables several interconnected devices but also gives rise chance for unauthorized parties to compromise sensitive information through wireless communication systems. Covert communication therefore has emerged as a potential candidate for ensuring data privacy in conjunction with physical layer transmission to render two lines of defense. In this paper, we aim to enhance the individual transmission of nearby users in non-orthogonal multiple access (NOMA) systems under scenarios of an eavesdropper who monitors covert transmission before decoding covert information.

The parathyroid hormone type 1 receptor (PTH1R) plays a crucial role in modulating various physiological functions and is considered an effective therapeutic target for osteoporosis. However, a lack of detailed molecular and energetic information about PTH1R limits our comprehensive understanding of its activation process. In this study, we performed computational simulations to explore key events in the activation process, such as conformational changes in PTH1R, Gs protein coupling, and the release of guanosine diphosphate (GDP).

Application of deep learning in automated localization and interpretation of coronary artery calcification in oncological PET/CT scans.

Coronary artery calcification (CAC) is a key marker of coronary artery disease (CAD) but is often underreported in cancer patients undergoing non-gated CT or PET/CT scans.
