We report a novel method termed matrix suppressed laser desorption/ionization to improve the analysis of low-mass molecules by MALDI-TOF mass spectrometry. In this method, surfactant cetrimonium bromide (CTAB) is added conventional α-cyano-4-hydroxycinnamic acid solution prepare MALDI samples. During process, presence CTAB could substantially or even completely suppress matrix-related ion background. As result, very clean spectra can be routinely obtained in range. addition, significantly...

Harmful algal blooms formed by fast-growing, ephemeral macroalgae have expanded worldwide, yet there is limited knowledge of their potential ecological consequences. Here, we select intense green tides Ulva prolifera in the Yellow Sea, China, to examine consequences these blooms. Using 28-isofucosterol surface sediment as a biomarker algae, identified settlement region massive floating algae area southeast Shandong Peninsula southern Sea. The responses phytoplankton assemblage from deep...

Abstract Kuroshio, the strongest west boundary current of Pacific Ocean, has significant impacts on oceanographic conditions and ecological processes Pacific‐Asian marginal seas through exchange water, heat, materials. In two cruises organized in East China Sea (ECS) Yellow spring 2014, observations picosized nanosized phytoplankton assemblages using flow cytometry reflected potential Kuroshio intrusion communities, particularly ECS. The distribution pattern Prochlorococcus ECS clearly...

In this work, the atomic level doping of Sn into Ga2O3 films was successfully deposited by using a plasma-enhanced layer deposition method. Here, we systematically studied changes in chemical state, microstructure evolution, optical properties, energy band alignment, and electrical properties for various configurations Sn-doped films. The results indicated that all have high transparency with an average transmittance above 90% over ultraviolet visible light wavelengths. X-ray reflectivity...

In this paper, high-quality β-Ga2O3 films were grown on silicon substrates by plasma-enhanced atomic layer deposition (PEALD). Effects of annealing temperature thin studied. Atomic force microscopy (AFM), X-ray diffraction (XRD), photoelectron spectroscopy (XPS), reflection (XRR), and ultraviolet (UV) emission used to systematically characterize Ga2O3 films. AFM test results showed that as increased from 500 900 °C, the roughness film 0.542 1.58 nm. XPS concentration oxygen vacancies in...

The identification of core genes involved in the biosynthesis saxitoxin (STX) offers a great opportunity to detect toxic algae associated with paralytic shellfish toxins (PST). In Yellow Sea (YS) China, both and nontoxic Alexandrium species are present, which makes it difficult issue specifically monitor PST-producing algae. this study, quantitative PCR (qPCR) assay targeting sxtA4, domain sxt gene cluster that encodes unique enzyme STX biosynthesis, was applied analyze samples collected...
