A small size broadband microstrip patch antenna for 14.0GHz radar application with multiple substrates had been fabricated using LTCC technology. A combination of a relatively low dielectric constant LTCC substrate and a relatively high dielectric constant LTCC substrate had been incorporated to reduce the effect of trade-off relationship between antenna(More)
Zinc oxide nanoparticles (ZnO NPs) have been widely used in cosmetics and sunscreens, advanced textiles, self-charging and electronic devices; the potential for human exposure and the health impact at each stage of their manufacture and use are attracting great concerns. In addition to pulmonary damage, nanoparticle exposure is also strongly correlated with(More)
Silver nanoparticles (AgNPs) attract considerable public attention both for their antimicrobial properties and their potential adverse effects. In the present study, endoplasmic reticulum (ER) stress was used as a sensitive and early biomarker to evaluate the toxic potential of AgNPs in three different human cell lines in vitro and in vivo in mice. In 16HBE(More)
Integrating covalent organic frameworks (COFs) with other functional materials is a useful route to enhancing their performances and extending their applications. We report herein a simple encapsulation method for incorporating catalytically active Au nanoparticles with different sizes, shapes, and contents in a two-dimensional (2D) COF material constructed(More)
With rapid development of novel nanomaterials (NMs), the state of the art technologies with high efficiency and high-throughput characteristics had been applied for nanosafety evaluation. High-content screening (HCS), a cell-based multi-parametric image analysis technique, was adopted in the evaluation of eight different NMs in this study. A set of(More)
Taxol (paclitaxel) is a diterpenoid compound with significant and extensive applications in the treatment of cancer. The production of Taxol and relevant intermediates by engineered microbes is an attractive alternative to the semichemical synthesis of Taxol. In this study, based on a previously developed platform, the authors first established taxadiene(More)
Indoor air quality has great impact on the human health. An increasing number of studies have shown that printers could release particulate matters and pose adverse effects on indoor air quality. In this study, a thorough investigation was designed to assess the aerosol printer particle total number concentration (TNC) and size distribution in normal office(More)
A broadband circularly-polarized (CP) stacked patch antenna to be realized in LTCC (low temperature co-fired ceramic) technology was presented. The proposed antenna was composed of the two-layer stacked patch and LTCC substrate. It was shown that the wide bandwidth was caused by a two-frequency resonance. The CP operation was obtained by cutting corners.(More)
