Zeolitic imidazolate framework-8(ZIF-8) and its composites have diverse applications. However,ZIF-8-based nanocomposites are mainly used as carriers in biomolecular delivery, with the functions of metal ions and ligands rarely used to modulate the biofunctions. In this work, dendritic mesoporous organosilica nanoparticles(DMONs) with tetrasulfide bond were used to confine ZIF-8 growth partially inside mesopores as a novel nanocomposite for m RNA delivery. Each component in the resultant DMONs-ZIF-8 contributed to m RNA delivery applications, including high loading benefitting from positively charged ZIF-8 and large mesopores of DMONs, endosomal escape promoted by the imidazole ring of ZIF-8, and long-term glutathione depletion mediated by both zinc ions and tetrasulfide *** together, DMONs-ZIF-8 demonstrated enhanced m RNA translation and better transfection efficiency than commercial products and toxic polymer-modified DMONs in vitro and in vivo.

Photovoltaic metal halide perovskite solar cells(PSCs) convert light to electricity more efficiently than crystalline silicon cells, and the cost of materials used to make them is lower than that of silicon *** efficiency is not a core issue affecting the application of perovskite solar cells in special *** present, stability is the major technical encounters that hinders its further commercial development. Microstrain in PSCs is currently a significant factor responsible for the device's instability. Strain-induced ion migration is widely believed to accelerate perovskite degradation even when external stimuli are ***, it is imperative to study strain to enhance the stability of PSCs. This paper reviews recent developments to understand strain's origin and effect mechanisms on performance of PSCs, including ion migration,failure behavior, defect formation, and its effect on photoelectric properties, stability, and ***, several well-known strain management strategies are systematically introduced based on the strain effect mechanism and strain engineering on the film, providing more clues for further preparation with increased stability. The manipulation of external physical strain applied from films to entire devices has been extensively studied. Furthermore, recommendations for future research directions and chemical approaches have been provided. It is emphasized that strain engineering plays a crucial role in improving the efficiency and longevity of PSCs. Tensile strain causes rapid degradation, while moderate compressive strain and external strain control could improve properties and stability. Efforts should focus on controlling compressive strain to mitigate residual tensile strain and introducing it in a controlled manner. Future research endeavors may focus on exploring these pathways to improve the efficiency and lifespan of PSCs.

Phototherapy, including photodynamic therapy(PDT) and photothermal therapy (PTT), is a promisingmethod of tumor treatment, which has the advantages ofstrong specificity and small side effects. However, PDT willaggravate the hypoxic environment in tumor cells, and PTTwill lead to heat-resistant reaction, both of which will make theorganism quickly produce heat shock proteins (HSPs) toprotect itself, thus seriously hindering the therapeuticefficiency of phototherapy. As a natural HSPs inhibitor,quercetin (QR) provides a feasible way to solve this ***, a kind of metal organic framework (MOF), Fe-TCPP(FT), was used as a delivery material and photosensitizer tobuild a chemo-phototherapy platform, and QR was used as achemotherapy drug and HSPs inhibitor. On this basis, the nanoparticles (NPs) were modified with PEG-CPP30 (a cellpenetratingpeptide that specifically recognizes human breast cancer MCF-7 cells), which showed excellent targetingcapacity and biocompatibility. The combination of chemotherapy and phototherapy significantly improved the anti-cancereffect. At the same time, NPs also showed prominent anti-HSPs effect. The effective connection of the two played acomplementary role in the process of tumor treatment, which provided a new strategy for the accurate and efficienttreatment of tumors in the future.

As the simple dispersion model tested is not sufficiently accurate to predict the SO2 concentration in complex terrain commonly encountered amongst high rise buildings in Hong kong, and the lack of comprehensive local wind data at most sites prevents the use of more advanced dispersion model to assess the impact of major air pollutant sources, a receptor model approach is adopted for the apportionment of air pollution sources in Hong kong. The preliminary results obtained are presented and discussed.
