| 1 | 小婴儿腰椎穿刺脑脊液参考值显示文摘研究背景既往有关脑脊液(CSF)参考值的研究为单中心研究,且样本量较小,因此其应用价值有限。研究新知这项多中心横断面调查研究确定了不同日龄段婴儿的CSF参考值,并且提供了日龄相关CSF百分位参考曲线。 | Joanna Thomson Heidi Sucharew Andrea T. Cruz Lise E.

| 2 | Magnetic poly(acrylic acid)-based hydrogels for rapid ammonium sorption and efficient sorbent separation from sewage显示文摘Ammonium sorption and recovery processes typically take place in conventional packed columns,with a configuration that enables maximum sorption by the sorbents.However,batch or semi-continuous operations in packed columns have associated issues such as scaling and frequent backwashing requirements,which are economically prohibitive.As an alternative,ammonium sorption could occur in well-mixed continuously stirred tanks,which would allow for the ammonium sorption process to be retrofitted in existing wastewater treatment plants,provided that efficient sorbent separation can be achieved.This study demonstrates,for the first time,the preparation of magnetic poly(acrylic acid)-based(PAA)ammonium sorbents through the incorporation of magnetic(Fe_(3)O_(4))nanoparticles(MNP)produced via scalable and cost-effective electrochemical synthesis.The MNP and PAA hydrogels were synthesized independently and the MNPs subsequently integrated into the PAA hydrogel network by particle diffusion and physical entrapment.No adverse effects on swelling and ammonium sorption following immersion in either synthetic or real sewage were observed after MNPs were incorporated into the hydrogels.Importantly,PAA-MNP hydrogels demonstrated high ammonium sorption efficiencies(80-93%)in real sewage and achieved rapid ammonium recovery of 73±1.1% within 15 min of mild acid washing(pH 4)15 min at a maximum recovery. | Heidy Cruz Miriam Yap Gabon Sirajus Salehin Thomas Seviour Bronwyn Laycock Ilje Pikaar | 2021 | Environmental Science and Ecotechnology2021，，2： | 0 |
