Summary: This study explores the growth behaviors and colloidal stability of inorganic cesium lead bromide perovskite nanocrystals synthesized using the ligand-assisted reprecipitation method. It finds that long-chain ligands result in more homogeneous and stable nanocrystals, while short-chain ligands are unable to produce functional nanocrystals with desired sizes and shapes. Excessive amines or polar antisolvents lead to the transformation of nanocrystals into a non-perovskite structure with poorer emission functionalities and larger size distributions.

Summary: In this research, the physical properties of galena ore were determined, and the microstructure and particle size of galena powder were investigated using SEM and EDS. The results confirmed that the as-received galena ore was mainly lead sulfide (PbS). The high-vibration milling machine produced nanoscale particles of about 90 nm in a short time. The sintered samples showed smaller grain size compared to the starting galena ore, with a high relative sinter density achieved under vacuum.

Summary: The surface structures or shapes of metal nanocrystals strongly influence their catalytic performance. Electrochemical square-wave potential (SWP) method is advantageous in the shape-controlled synthesis of Pt-group metal nanocrystals with high-index facets. In this study, the effect of electrolyte (H2SO4 and Na2SO4) on the shape evolution of Pt nanocrystals prepared by the SWP method was investigated. It was found that high-index faceted Pt nanocrystals can be obtained in H2SO4 electrolyte, while mainly low-index facets are formed in Na2SO4 electrolyte. The pH value was identified as a key factor in the shape evolution.

Summary: A new transmetallation approach is introduced for the synthesis of metal oxide nanocrystals, where the inclusion of group 13 cations facilitates the efficient synthesis of Cu2O nanocrystals with size/morphology control. Continuous-injection procedure allows monitoring of the reactivity of the precursor and catalyst, showing that M3+ catalysts drive esterification to generate Cu+-OH monomers required for condensation. Ga3+ is identified as an optimal catalyst, producing Cu2O nanocrystals with unique cubic morphology due to rapid transmetallation kinetics.

Summary: This study reports a robust method to synthesize single-crystalline Ag nanocubes with high purity (>95%) and uniform size in oil phase, which has received little attention. The evolution of Ag nanoparticles from different reaction times reveals that multiply twinned seeds and single-crystalline seeds were formed together in the early stage of the reaction. The synthetic parameters such as temperature, air flow, and the concentration of cupric chloride and AgNO3 precursors have been systematically investigated to control the morphology and size of Ag nanocubes, with temperature playing a crucial role.

Summary: Researchers found through in situ studies that in the early stage of the CdSe nanoplatelet reaction, both isotropic nanocrystals and mini-nanoplatelets form in the absence of short-chain ligands, but most precursors are consumed in isotropic growth. The addition of acetate induces a dramatic shift towards nearly exclusive 2D growth of already existing mini-nanoplatelets. Therefore, mature nanoplatelets only grow through a subtle interplay between myristate and acetate, with the latter catalyzing fast lateral growth of the side facets of the mini-nanoplatelets.

Summary: A self-driven electrical stimulation-promoted cancer catalytic therapy and chemotherapy is proposed by integrating a human-driven triboelectric nanogenerator (TENG) with an implantable and biodegradable nanofibrous patch. The patch incorporates doxorubicin (DOX) and graphitic carbon nitride (gC3N4) to enhance the peroxidase (POD)-like activity of g-C3N4 and release DOX under a weakly acidic tumor microenvironment (TME), achieving synergistic therapy. The in vitro and in vivo experimental results demonstrate superior tumor suppression outcome and suggest a new complementary strategy for catalytic therapy of solid tumors using multifunctional nanofibrous patches.

Summary: Sonodynamic therapy (SDT) is a promising strategy for cancer treatment, but the inefficient production of reactive oxygen species (ROS) limits its applications. This study developed a piezoelectric nanoplatform with manganese oxide (MnOx) and bismuth oxychloride nanosheets (BiOCl NSs) to enhance SDT. The nanoplatform exhibited piezotronic effect to promote charge separation and transport, leading to enhanced ROS generation. Additionally, the MnOx on the nanoplatform showed multiple enzyme-like activities, which downregulated intracellular glutathione (GSH) level and disintegrated hydrogen peroxide (H2O2) to generate oxygen (O2) and hydroxyl radicals (.OH). The nanoplatform demonstrated excellent biocompatibility and tumor suppression in a murine model of 4 T1 breast cancer under ultrasound irradiation. This work presents a feasible pathway for improving SDT using piezoelectric platforms.

Summary: Sonodynamic therapy (SDT) is a promising cancer treatment strategy with low invasiveness and high tissue penetration. However, the lack of efficient sonosensitizers has hindered its application. In this study, iron-doped and oxygen-deficient bismuth tungstate nanosheets (BWO-Fe NSs) with piezotronic effect were synthesized to enhance SDT. The presence of oxygen defects and Fenton reactivity in BWO-Fe improved its activation by ultrasound and amplified the cellular oxidative damage.

Summary: Ultrasound-triggered sonodynamic therapy (SDT) is a promising method for cancer treatment due to its non-invasive nature and high tissue penetration ability. However, current sonosensitizers have low yields of free radicals. In this study, organic semiconductor π-conjugated covalent organic framework nanocages (COFNs) were developed as efficient sonosensitizers to enhance free radical production and improve cancer therapy. The COFNs exhibited significantly improved SDT performance through enhanced electron utilization and cavitation effect, resulting in increased ultrasound pressure and O-1(2) production. In vitro and in vivo experiments confirmed the elevated SDT performance, demonstrating high tumor suppression in refractory breast cancer. This work provides a promising strategy to develop high-performance sonosensitizers for cancer therapy.

Summary: This study presents a robust sonodynamic and gas cancer therapeutic platform based on strontium-doped barium titanate piezoelectric nanoparticles. The doping of strontium improves the piezoelectricity and enhances the production of reactive oxygen species upon ultrasound stimulation. In addition, the surface-tethered L-arginine is decomposed by the generated reactive oxygen species, leading to the controlled release of nitric oxide gas at the tumor site. Remarkable tumor suppression rate in a mouse model demonstrates the effectiveness of this strategy.
