In recent years, the design of various ultrasound responsive echogenic nanomaterials offers many advantages such as deep tissue penetration, high signal intensity, colloidal stability, biocompatibility and less expensive for ultrasound-based cancer cell imaging while providing the option to monitor the progress of tumor volume during the treatment. Further, the ability of nanomaterials to combine photo-thermal therapy (PTT) and chemotherapy has opened a new avenue in the development of cancer theranostics for synergistic cancer therapy. Herein, we report MoS nanoflowers (NFs) surface decorated with CuS nanorods (NRs) and folic acid-derived carbon dots (FACDs) using cystine-polyethyleneimine (PEI) linker for PTT-chemotherapy.

In the realm of hybrid nanomaterials, the construction of core/shell nanoparticles offer an effective strategy for encompassing a particle by a polymeric or other suitable material, leading to a nanocomposite with distinct features within its structure. The polymer shell can be formed via nanoprecipitation, optimized by manipulating fluid flow, fluid mixing, modulating device features in microfluidics. In addition to the process optimization, success of polymer assembly in encapsulation strongly lies upon the favorable molecular interactions originating from the diverse chemical environment shared between core and shell materials facilitating formation of core/shell nanostructure.

The development of high-performance electrocatalysts for hydrogen evolution reaction (HER) in different pH conditionsis pivotal in producing green hydrogen, but remains challenging. Herein, we regulate the p-d orbitals hybridization between B and Pt for effective and durable HER at all pH ranges by controlling the inserted B atom. Consequently, the optimized B-doped Pt catalysts with 20 at.

Despite being studied for almost two centuries, aromaticity has always been a controversial concept. We previously proposed a unified aromatic rule for π-conjugated systems by two-dimensional (2D) superatomic-molecule theory, where benzenoid rings are treated as period 2 2D superatoms (3π-N, 4π-O, 5π-F, 6π-Ne) and, further, bond to form 2D superatomic molecules. Herein, to build a 2D periodic table, we further extend the theory to period 3 (7π-P, 8π-S, 9π-Cl, 10π-Ar) and period 1 (1π-H, 2π-He) elements.

In this study, we investigate how modulating organic spacers in perovskites influences their X-ray detection performance and reveal the mechanism of low-dose detection with high sensitivity using femtosecond-transient absorption spectroscopy (fs-TAS). Particularly, we employ N,N,N',N'-tetramethyl-1,4-phenylenediammonium (TMPDA) and N,N-dimethylphenylene-p-diammonium (DPDA) as organic spacers to synthesize 2D perovskite single crystals (SCs). We find that DPDA-based SCs exhibit reduced interplanar spacing between inorganic layers, leading to increased lattice packing.
