- Abstract:
- ... Herein, a sensitive fluorescence (FL) biosensor for the assay of ascorbic acid oxidase (AAO) was established based on the fluorescence resonance energy transfer (FRET) between MoS₂ quantum dots (MQDs) and CoOOH nanoflakes. CoOOH nanoflakes as effective FL quencher could quench the FL signal of MQDs on the basis of FRET. When ascorbic acid (AA) was added to the MQDs/CoOOH nanoflakes system, the FL ...

Panorpa diqingensissp. n. can be distinguished from its congeners by vertex dark brown, and occiput yellow; pleura dark brown; gonocoxites bearing a cluster of stout black setae on inner apex; parameres S-shaped in male genitalia. Panorpa dispergenssp. n. can be readily differentiated fr ...

- Abstract:
- ... Remote sensing data have been widely used in research on population spatialization. Previous studies have generally divided study areas into several sub-areas with similar features by artificial or clustering algorithms and then developed models for these sub-areas separately using statistical methods. These approaches have drawbacks due to their subjectivity and uncertainty. In this paper, we pre ...

To study the composite effect of this new type of composite structure, the slip behavior of bamboo–concrete shear connectors was first studied through push-out tests. Subsequently, four-point bending tests of ten bamboo–concrete composite beams were carried out. The results show that the fai ...

Seed removal by birds has been recognized as an important part of seed dispersal process in patchy forest areas; however, few studies have focused on the contribution of both plant and bird traits to seed removal. In this study, field data of seed removal for Taxus chinensis was combined with the data of bird and plant traits for analysis. The relevant traits of plants and birds that influenced T. ...

Trypsin can hydrolyze cytochrome c into heme-peptide fragments with peroxidase-like activity. In the presence of hydrogen peroxide, the fragments can generates hydroxyl radicals, which can oxidize o-phenylenediamine (OPD) to f ...

- Abstract:
- ... In matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS), the analyte is usually distributed unevenly throughout the sample spot. The area with aggregated analyte molecules contributing abundant signal, is termed as “sweet spot”, which results in poor detection reproducibility and makes it impossible to quantify analytes without internal standards. We proposed a strategy to elim ...
