There is no commonly approved approach to detect and quantify the health-relevant microbial exposure in moisture-damaged buildings. In 39 single-family homes with severe moisture damage, we studied whether concentrations of viable microbes in building material samples are associated with health among 71 adults and 68 children, and assessed with symptoms questionnaires, exhaled NO, and peak expiratory flow (PEF) variability. Symptoms were grouped into three scores: upper respiratory symptoms, lower respiratory symptoms, and general symptoms. The homes were divided into three groups based on viable counts of fungi, actinomycetes, and total bacteria cultivated from building material samples. Highest group of actinomycete counts was associated with more general symptoms, worse perceived health, and higher daily PEF variability (aOR 12.51; 1.10-141.90 as compared to the lowest group) among adults, and with an increase in lower respiratory symptoms in children, but the confidence intervals were wide. We observed significant associations of fungal counts and total microbial score with worse perceived health in adults. No associations with exhaled NO were observed.

Construction and optimization of stable atomically dispersed metal sites on SiO surfaces are important yet challenging topics. In this work, we developed the amino group-assisted atomic layer deposition strategy to deposit the atomically dispersed Pt on SiO support for the first time, in which the particle size and ratio of Pt entities from single atom (Pt) to atomic cluster (Pt ) and nanoparticle (Pt ) on the SiO surface were well modulated. We demonstrated the importance of dual-site synergy for optimizing the activity of single-atom catalysts.

The creation of spatially coupled meso-/microenvironments with biomimetic compartmentalized functionalities is of great significance to achieve efficient signal transduction and amplification. Herein, using a soft-template strategy, UiO-67-type hierarchically mesoporous metal-organic frameworks (HMMOFs) were constructed to satisfy the requirements of such an artificial system. The key to the successful synthesis of HMUiO-67 is rooted in the utilization of the preformed cerium-oxo clusters as metal precursors, aligning the growth of MOF crystals with the mild conditions required for the self-assembly of the soft template.

Bisphenol A (BPA) poses a significant environmental threat due to its widespread use as an industrial chemical and its classification as an environmental endocrine disruptor. The urgent need for effective BPA removal has driven research toward innovative solutions. In this study, we present the synthesis and application of a novel 2D-3D spherically hierarchical ZnInS (ZIS) photocatalyst for the photocatalytic degradation of BPA under visible light for the first time.

An efficient Pd-catalyzed regioselective intramolecular aerobic oxidative dehydrocoupling of BH/CH between -carborane and arenes has been achieved with the construction of a series of five-, six- and seven-membered rings under mild reaction conditions. Control experiments indicate that B-H activation proceeds preferentially over the aryl C-H. These new polyarene-carborane conjugates have potential applications in materials as demonstrated by pyrene fused -carborane that exhibits unique dual-phase emission, intramolecular charge transfer (ICT), and aggregation-induced emission (AIE) properties.
