The high performance and increased tumor-targeting accumulation of magnetic nanocrystals (MNCs) are the most important considerations in cancer targeted hyperthermia (TMH). To achieve these goals, our study was firstly done using well-established fluorescence/magnetic Mn–Zn ferrite MNCs (core size: 14 nm) as multi-modal imaging contrast agents highly-efficient "heat generators", which were coated with a biocompatible PEG-phospholipid (DSPE-PEG2000) further modified by cyclic tripeptide...

The properties of plant residue-derived biochars (PLABs) and animal waste-derived (ANIBs) obtained at low high heating treatment temperatures (300 450°C) as well their sorption dibutyl phthalate (DBP) phenanthrene (PHE) were investigated in this study. higher C content PLABs could explain that CO2-surface area (CO2-SA) was remarkably relative to ANIBs. OC aromatic two key factors influencing the CO2-SA biochars. Much surface ANIBs than bulk likely explained exhibited DBP PHE compared PLABs....

Abstract. This study investigates the seasonal variation, molecular distribution and stable carbon isotopic composition of diacids, oxocarboxylic acids α-dicarbonyls to better understand sources formation processes fine aerosols (PM2.5) in Beijing. The concentrations total dicarboxylic varied from 110 2580 ng m−3, whereas oxoacids (9.50–353 m−3) dicarbonyls (1.50–85.9 were less abundant. Oxalic acid was found be most abundant individual species, followed by succinic or occasionally...

Understanding the response of vegetation spring phenology to climatic factors in arid regions is crucial for projecting land-climate interactions ecosystems under climate change. The Xinjiang region, an important part northern China with complex features, was selected as a case study. We investigated impact temperature, precipitation, and solar radiation on start growing season (SOS) using long-term series normalized difference index, data from 1982 2014, partial least squares regression...

Abstract Background/Aim With the pharmaceutical innovation and clinical knowledge updating, continuing education on-the-job training are extremely important for improving community pharmacists’ professional competence. Previous often adopted traditional lecture-based teaching, efficacy was limited. The aim of this study is to develop a new strategy pharmacist training. Methods Based on BOPPPS (Bridge-in, Objective, Pre-assessment, Participatory Learning, Post-assessment Summary) teaching...

CWMFC is a novel technology that has been used for almost decade concurrent wastewater treatment and electricity generation in varying scopes of domestic, municipal, industrial applications since its implementation 2012. Its advantage low-cost enhanced sustainable bioelectricity gained considerable attention. Nevertheless, the overall efficiency this inclined by several operating factors configuration strands, such as pH, sewage composition, organic loading, electrode material, filter media,...

Satellite remote sensing data, such as moderate resolution imaging spectroradiometers (MODIS) and advanced very high-resolution radiometers (AVHRR), are being widely used to monitor sea ice conditions their variability in the Bohai Sea, southernmost frozen Northern Hemisphere. Monitoring characteristics of Sea can provide crucial information for disaster prevention marine transportation, oil field operation, regional climate change studies. Although these satellite data cover study area with...
