Nano‐networks via reaction‐induced self‐assembly coordinate spatiotemporal multi‐drug delivery for acute kidney injury therapy

open access: yesBMEMat, EarlyView.
Multifunctional nano‐networks (NNWs) are prepared via reaction‐induced self‐assembly (RISA) of spermidine (SPD), epigallocatechin gallate (EGCG), 2‐formylphenylboronic acid (2‐FPBA), and deferoxamine (DFO) through dynamic iminoboronate bonds. These NNWs leverage the oxidative AKI microenvironment to trigger disintegration, enabling site‐specific ...

Evaluation and alert of water environment security before and after " Five-Water-Governance" in Zhejiang province(浙江省“五水共治”决策前后水环境安全评估预警)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2018
水环境安全不仅是生态环境问题,更是直接关系区域经济发展和政治稳定的问题.基于“压力-状态-响应”模型和“五水共治”决策构建评估指标体系,应用层次分析评估方法,对浙江省治水前后水环境安全进行评估与预警.结果显示:自2014年治水工作开展以来,浙江省水环境安全趋于好转,安全指数呈上升趋势,2014年、2015年较2013年分别提高了 7.38%和16.85%,水环境安全从预警状态转为较安全状态.按照“五水共治”分阶段规划要求,浙江省2017和2020年水环境安全度值分别达到0.754 5和0.798 9 ...

浙江省鸟类多样性与区系分析

open access: yes野生动物学报, 2019
综合文献报道以及本课题组积累的资料,严格核定近年来的浙江鸟类新增种以及全省各鸟种的居留型和区系类型,并按照鸟类最新分类系统编制《浙江省鸟类多样性名录》,这对于理解地区鸟类多样性及其分布现状具有重要意义。结果显示:浙江省鸟类共计22目87科266属519种及26亚种,比《浙江鸟类名录更新》多36种及2亚种。全省鸟类以雀形目为主(236种),非雀形目鸟类以鸻形目种数(86种)最多。浙江省水鸟共计168种,其中鸻形目种数最多(83种);海鸟共计42种,其中鸥科种数最多(28种);猛禽共计52种 ...

A Research on Mobile Terminal Promotion Based on Big Data of Zhejiang Telecom [PDF]

open access: yes, 2016
2008年,中国电信业进行了重组,全面形成了中国电信、中国移动、中国联通三家综合性运营商全业务营销的模式,同时也意味着中国电信业打破垄断经营机制,形成了全面竞争的格局。八年来,中国电信在面临三大运营商之间竞争不断加剧的势态的同时,持续加快3G和4G网络的建设,加大手机移动用户的发展,以终端引领移动业务的发展,在移动业务市场上占有了一席之地。 然而,受国家政策指引,通信行业的资费在不断进行下调,近年来陆续实施了接听免费、漫游资费下调、宽带资费下调、流量不清零等政策,使得话音、宽带 ...

Correlating the Interfacial Chemistries With Ion Conduction and Lithium Deactivation in Hybrid Solid Electrolytes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The rapid ion transport characteristics of nano‐Li2S at the intrinsic/extrinsic interface in typical hybrid electrolytes have been detected at the atomic scale, enabling the Li || Li cell to cycle for over 3000 h. Inactive lithium (dead Li) is the key factor leading to the performance degradation of solid‐state Li metal batteries.

Runoff characteristics of Cao'e River and its effect on processes of the estuary(曹娥江径流特性及其对河口冲淤的影响)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2000
曹娥江径流具有浙闽山溪性强潮河口的若干特征,径流年际、年内变幅较大,洪水暴涨暴落,洪枯比极大,年内存在两个汛期,即梅汛期和台风汛期.根据曹娥江径流特性,本文讨论了曹娥江河口河床洪冲枯淤变化特性,径流对潮汐大小的间接影响以及径流对曹娥江口门外主槽出口方向的影响.

Design and Implementation of Infrastructural Projects Online Contracts Management System Based on C/S Framework [PDF]

open access: yes, 2015
21世纪是科技创新的世纪,我们的计算机技术以及互联网技术也在这个世纪日渐发展,我们社会的各个领域也因为计算机技术的发展发生了巨大的变化。在计算机互联网技术领域,浙江省针对国库集中支付改革推出了金财工程管理软件供地方财政部门使用,财政支付由于互联网技术的推广,程序越发简便,支付效率大大提高。随着改革的深入,政府投资项目(简称基建项目)资金也陆续进入改革范畴。由于政府投资项目不同于部门其他项目,其资金支付具有连续性、分期性、大额性以及完整性,项目资金的支付大多以签订合同的形式有序进行。所以 ...
