Aggregation-induced emission luminogens (AIEgens) exhibit efficient cytotoxic reactive oxygen species (ROS) generation capability and unique light-up features in the aggregated state, which have been well explored image-guided photodynamic therapy (PDT). However, limited penetration depth of light tissue severely hinders AIEgens as a candidate for primary or adjunctive clinical applications. Coincidentally, microwaves (MWs) show distinct advantage deeper tissues than light. Herein, first...
Abstract Malignant tumors are considered “unresectable” if they adhere to vital structures or the surgery would cause irreversible damages patients. Though a variety of cytotoxic drugs and radiation therapies currently available in clinical practice treat such tumor masses, these therapeutic modalities always associated with substantial side effects. Here, we report an injectable nanoparticle-based internal source that potentially offers more efficacious treatment unresectable solid without...
Gas evolution during electrochemical deposition has long been regarded as undesired and deliberately suppressed. Here, we show a new role of electrochemically evolved hydrogen bubbles, serving both templates reducing agent to form hollow Au nanoparticles via electroless deposition. Hollow gold with complete nanocrystalline shell 50 nm core were fabricated. By controlling the thickness, particle size can be varied from 100 150 nm. The process is very simple, scalable, high throughput. Using...
We have studied the effect of magnetostatic interactions on overall shape hysteresis loops for arrays single domain particles. A computational model was used to calculate major particles with an easy axis along applied field. The shear loop, and consequent loss squareness, is found increase both interaction strength standard deviation switching field This has been tested several shapes particles, including axes parallel perpendicular plane. For cylindrical we find excellent fit between data....
Au–PtCu core–shell nanoparticles were successfully synthesized via galvanic replacement of Cu by Pt on hollow Au nano-spheres. Characterizations the conducted X-ray diffraction (XRD), transmission electron microscopy (TEM), and electrochemical measurements. Results indicate 2–2.5 times higher specific activity mass catalysts than commercial black Pt/C in oxygen reduction reaction (ORR), measured a rotating disk electrode system. Besides, thinner PtCu coating (25 nm thick, deposition time 20...
We report the successful synthesis of monodispersed Cu2S nanocrystals and subsequent formation highly ordered nanocrystal superlattices. The is performed under ambient air conditions using simple experimental setups, making process both accessible scalable. By systematically tuning reaction temperature duration, we demonstrate precise control over size, which crucial in achieving uniformity monodispersity. Furthermore, uncover a previously unidentified growth mechanism that plays key role...
A facile method has been developed to synthesize Au/Pd core-shell nanoparticles via galvanic replacement of Cu by Pd on hollow Au nanospheres. The unique were characterized X-ray diffraction, photoelectron spectroscopy, transmission electron microscopy, ultraviolet-visible and electrochemical measurements. When the concentration solution was decreased, grain size polycrystalline nanospheres reduced, structures became highly porous. After shell formed these nanospheres, morphology structure...

Single-crystal silver dendrite structures, which possess a high surface area along with narrow gaps and sharp edges, have been widely explored as enhanced Raman scattering substrates for catalytic biosensing applications. With one of the simplest galvanic reactions, reaction AgNO3 Cu, Ag dendrites can easily be produced. Here, we report new findings about this growth mechanisms. A series experiments revealed much more complicated mechanism: metal could form through reduction Ag+ by...
