Strategic Approach for Enhancing Sensitivity of Ammonia Gas Detection: Molecular Design Rule and Morphology Optimization for Stable Radical Anion Formation of Rylene Diimide Semiconductors

A strategic approach to enhance the sensitivity of ammonia gas detection using n-type organic semiconductor thin film is developed by boosting the efficiency of ammonia-gas-induced stable radical anion formation, which enables simultaneous achievement of excellent gas-responsivity and detection limit. Abstract Herein, a strategic approach...

Engineered Polymeric Carbon Nitride Additive for Energy Storage Materials: A Review

Polymeric carbon nitride (PCN) has been increasingly studied in energy storage fields. Herein, the recent developments on the constructions and applications of PCN-based nanocomposites in various types of batteries and supercapacitors are summarized with a focus on engineering PCN into electrode materials, accompanied by providing mechanism insights...

An Integrated Microfluidic‐SERS Platform Enables Sensitive Phenotyping of Serum Extracellular Vesicles in Early Stage Melanomas

A detection platform that integrates a circulating nanomixing-microchip and a multiplexing surface-enhanced Raman spectroscopy barcoding system for sensitive phenotypic characterization of serum extracellular vesicles, without extensive sample pre-enrichment is developed. This platform, combined with the panel of melanoma-associated biomarkers, has...

Dopant‐Free Polymer HTM‐Based CsPbI2Br Solar Cells with Efficiency Over 17% in Sunlight and 34% in Indoor Light

A new polymer, PDTDT, is developed as hole-transporting material for CsPbI2Br solar cells. Using PDTDT, an ultra-high efficiency of 17.36% with V OC of 1.42 V under one sun and 34.20% with V OC of 1.14 V under 200 lux indoor light are achieved. PDTDT based cells also show superior/comparable stability to dopant-free P3HT reference. Abstract...

Purely Electrical Controllable Complete Spin Logic in a Single Magnetic Heterojunction

Purely electrical controllable complete spin logic is demonstrated in a single Pt/IrMn/Co/Ru/CoPt heterojunction. By applying current pulses along with two orthogonal directions, all 16 Boolean logic functions can be realized in a purely electrical way, relying on the electrical manipulation of magnetic-field-free spin-orbit torque switching. This study...

Self‐Delivered Supramolecular Nanomedicine with Transformable Shape for Ferrocene‐Amplified Photodynamic Therapy of Breast Cancer and Bone Metastases

A self-delivery supramolecular nanoplatform (Ce6-CD/Fc-pep-PEG) is constructed to co-deliver ferrocene and chlorin e6 for self-amplified chemo-photodynamic therapy of breast cancer and bone metastases. Its shape-transforming capacity further improves the penetration and retention of Ce6-CD/Fc-pep-PEG in the tumor, which enhances the therapy efficiency...

Engineering Synergistic Edge‐N Dipole in Metal‐Free Carbon Nanoflakes toward the Intensified Oxygen Reduction Electrocatalysis

Edge-suffused and graphite-analogous nitrogen-doped carbon nanoflakes (NCF) are fabricated by a tandem catalytic graphitization and nitrogen modification strategy. The key electronic synergism of the edge-type pyridinic-N/graphitic-N dipole is identified to empower NCF with superior electrocatalytic oxygen reduction performances. Abstract Nitrogen...

Bionic Adaptive Thin‐Membranes Sensory System Based on Microspring Effect for High‐Sensitive Airflow Perception and Noncontact Manipulation

A flexible and adaptable airflow sensor enabled by bioinspired thin-membrane based on reversible microspring effect is described. The graphene/single-walled nanotubes structured thin membrane can respond rapidly and sensitively to applied airflow with ultralow detection limit, fast response time, and wide working range. Furthermore, a smart window and...

Mechanically Robust and Flexible Films of Ionic Liquid‐Modulated Polymer Thermoelectric Composites

Ionic liquid-assisted fabricated flexible films of polymer composites show a high thermoelectric performance (power factor of 106.1 ± 8.2 µW m−1 K−2) and strong mechanical robustness (tensile modulus of 4.2 ± 0.5 GPa, fracture strength of 133.4 ± 10.6 MPa). This study provides a promising way to help address the intractable issue of inferior mechanical...

Preclinical Cancer Theranostics—From Nanomaterials to Clinic: The Missing Link

The present review summarizes the in vivo preclinical status of various organic, inorganic, 2D, and hybrid nanomaterials employed in cancer theranostics. Performance outcomes of these systems in animal models and the limitations and challenges for their clinical translation are discussed. Strategies to enhance the biocompatibility of theranostic nanoparticles...
