TL;DR: The introduction of the spin unit not only enabled convenient sample introduction from one inlet to multiple separate channels in the multiplexed detection, but also elegantly solved the pressure cross-interference problem in themultiplexed volumetric bar-chart chip.
Abstract: A portable multiplexed bar-chart SpinChip (MB-SpinChip) integrated with nanoparticle-mediated magnetic aptasensors was developed for visual quantitative instrument-free detection of multiple pathogens. This versatile multiplexed SpinChip combines aptamer-specific recognition and nanoparticle-catalyzed pressure amplification to achieve a sample-to-answer output for sensitive point-of-care testing (POCT). This is the first report of pathogen detection using a volumetric bar-chart chip, and it is also the first bar-chart chip using a "spinning" mechanism to achieve multiplexed bar-chart detection. Additionally, the introduction of the spin unit not only enabled convenient sample introduction from one inlet to multiple separate channels in the multiplexed detection, but also elegantly solved the pressure cross-interference problem in the multiplexed volumetric bar-chart chip. This user-friendly MB-SpinChip allows visual quantitative detection of multiple pathogens simultaneously with high sensitivity but without utilizing any specialized instruments. Using this MB-SpinChip, three major foodborne pathogens including Salmonella enterica, Escherichia coli, and Listeria monocytogenes were specifically quantified in apple juice with limits of detection of about 10 CFU/mL. This MB-SpinChip with a bar-chart-based visual quantitative readout has great potential for the rapid simultaneous detection of various pathogens at the point of care and wide applications in food safety, environmental surveillance, and infectious disease diagnosis.

TL;DR: In this paper, the authors used graphite oxide to improve the hydrothermal stability and catalytic activity of metal-organic frameworks (MOFs), which are believed to play an important role in the practical applications of MOFs in catalysis.
Abstract: This paper aims to improve the hydrothermal stability and catalytic activity of metal–organic frameworks (MOFs), which are believed to play an important role in the practical applications of MOFs in catalysis. Our strategy is to incorporate graphite oxide into a typical MOF, namely HKUST-1 (Cu3(BTC)2, BTC = 1,3,5-benzenetricarboxylic acid; HKUST = Hong Kong University of Science and Technology), and the properties of MOF are successfully tailored by use of this strategy. The obtained MOF/graphite oxide composites show enhanced porosity with high surface areas and some meso/macropores. For the composite containing 8.7 wt % of graphite oxide, the surface area reaches 1257 m2 g–1, which is obviously higher than pure HKUST-1 (841 m2 g–1). The pore structure of composites favors the access of reactant molecules to active sites and accelerates mass transfer in channels. Furthermore, the incorporation of graphite oxide creates a more hydrophobic environment surrounding metallic sites, which prevents the coordina...

TL;DR: In this paper, the authors studied the oxygen permeation and stability of perovskite-type membranes at high temperatures and low oxygen partial pressures, and they found that the oxygen vacancy diffusivity and concentration gradient calculated from the unsteady-state and steady-state oxygen data for the three membranes decrease in the order of Sr > Ba > Ca.
Abstract: The oxygen permeation and stability of La0.2A0.8Co0.2Fe0.8O3-δ (A = Sr, Ba, Ca) perovskite-type membranes were studied at high temperatures and low oxygen partial pressures. The oxygen vacancy diffusivity and concentration gradient calculated from the unsteady-state and steady-state oxygen data for the three membranes decrease in the order of Sr > Ba > Ca. The activation energies for oxygen permeation increase in the order of Sr < Ba < Ca. The oxygen permeation data of the three membranes can be explained by the average bond energy, free volume, and critical radius of the materials. After exposure to air at 1173 K for 10 h, part of La0.2Sr0.8Co0.2Fe0.8O3-δ transforms to La2O3, SrO, CoO, and Fe and the crystallite size of the perovskite phase decreases. These changes were not observed for La0.2Ba0.8Co0.2Fe0.8O3-δ under the same conditions, indicating that La0.2Ba0.8Co0.2Fe0.8O3-δ membrane is much more stable than La0.2Sr0.8Co0.2Fe0.8O3-δ at high temperatures and low oxygen partial pressures.

TL;DR: In this paper, a summary review of research performed on the mechanical behavior of concrete-filled steel tube members and frames made from recycled aggregate concrete (RAC) is presented, and a prediction model for the strength of RACFST by considering whether the recycled coarse aggregates have been prewetted or not before fabrication of the structural members.
