Summary: A sandwich enzyme-linked dendrimer-aptamer assay (ELDAA) was developed to improve the detection performances of a traditional enzyme-linked immunosorbent assay (ELISA) using glass-bottom 96-micro-well plates. Poly(amidoamine) (PAMAM) dendrimers were immobilized onto the microwell surfaces and aptamers against human platelet-derived growth factor BB (PDGF-BB) were conjugated onto the surfaces via the immobilized PAMAM dendrimer templates. The ELDAA demonstrated a broader linear detection range and a lower limit of detection compared to the standard ELISA.

Summary: Molybdenum carbide (Mo2C) with sulfur modification has been developed as an efficient catalyst for hydrogen evolution reaction (HER). The sulfur atoms replace a portion of the oxygen atoms on the surface of Mo2C, activating the surface and improving the HER performance. Theoretical studies suggest that the strong hydrogen bonding of Mo atoms in the oxide layer is the primary reason for impaired HER performance, and sulfur modification weakens the Mo-H bond, leading to enhanced HER activity.

Summary: In this paper, two surface oxygen vacancy-rich TiO2 composite photocatalysts were successfully constructed using different methods. The excellent photocatalytic performance of Nd-Fe-(D-Vo)TiO2 was attributed to its doping energy and surface oxygen vacancies. The bonding of ellagic acid (EA) to the surface of TiO2 further improved the visible light absorption and photocatalytic performance, and Nd-Fe-(D-Vo)TiO2@EA achieved a high degradation degree of ethinyl estradiol.

Summary: This study investigated the effect of coating a non-biodegradable polymer on the degradation of a biodegradable polymer film. The results showed that the coated films had less degradation in the presence of enzymes, but the surface-deacetylated coated films could be degraded. Additionally, it was found that the coated films underwent deacetylation in seawater and exposed the underlying material, thereby promoting degradation.

Summary: This study investigates composites containing undoped and barium-doped Bi2WO6:Ba2 thorn for shielding against diagnostic X-ray. The results show that barium-doped Bi2WO6 has a higher attenuation effect compared to undoped Bi2WO6, and the attenuation coefficients increase with an increase in the amount of barium. The calculated parameters such as half-value layer, tenth-value layer, and 0.25 mm lead equivalent thickness demonstrate the optimal shielding performance of the sample with 7.5 mmol barium-doped Bi2WO6.

Summary: Blue ceramic nanopigments were prepared using clinoptilolite zeolite as a precursor. The pigment showed various intense blue colors based on the crystal structures of Co-willemite and spinel of Co-zinc aluminate and cobalt aluminate. Increasing zinc and decreasing cobalt content in the composition resulted in a high-intensity peaks pattern and crystalline particle structure with intense blue color. The blue pigment coated on ceramic tile exhibited high reflectance in the NIR range, making it a cool coating material.

Summary: Replicating the enzymatic surface microenvironment in vitro is challenging, but constructing an analogous model could facilitate our understanding of surface effects and aid in developing an efficient bioinspired catalytic system. In this study, five unique Cu2O morphologies were generated, and the surface morphology variations were found to be a consequence of differences in the exposure of low-index facets. The reactivity of Cu2O was found to be influenced by the proportion of {110} planes, with r-Cu2O exhibiting the highest reactivity.
