Flocculation of harmful algal blooms by modified fly ash Chunguang Miao1,a ,Xiangqin Wang*1,b ,Hong Zhang1,c 1Key Laboratory of Ion Beam Bioengineering, Hefei Institutes of Physical science, Chinese Academy of Science, Hefei, Anhui 230031, China amiaochun@mail.ustc.edu.cn, bxqwang@ipp.ac.cn,czh_elite@126.com Corresponding Author: Prof.Xiangqin Wang Keywords: Harmful algal blooms;Fly ash; Flocculation Abstract: The flocculants of fly ash(FA) and modified fly ash (mFA)were investigated in this study to evaluate their flocculation efficiencies in freshwater containing harmful algal blooms(HABs).
Although fly ash is effectively used for building materials and soil amendments, still large amount of fly ash is not effectively reuse.

Introduction Since material performance degradation could lead to the decline of bearing capacity, the actual working life of many existing concrete beam bridges is far less than the design value.
The degradation model of reinforced concrete under general atmospheric environment The durability degradation of material is the main reason for the degradation of bridge carrying capacity.
There are lots of reasons for the durability degradation of material.

When considering their possible applications, the fatigue resistance of photochromic materials has been considered.
Materials and Methods Woven fabric, a blend of polyester and cotton 65:35, was printed with Photopia Purple Ink (Matsui) of a concentration of 100 g.kg-1 using a screen printing technique. 
A standard method of fatigue resistance test of photochromic materials is based on a relatively high number of necessary cycles that cause a 50% decrease of initial shade intensity/optical density.
