“…This technique is very sensitive to changes in the interfacial properties of the modified electrodes caused by biorecognition events at the electrode surface [22,23]. For this reason, EIS is becoming an attractive electrochemical technique for numerous applications such as immunosensing [24], enzyme activity determination [25], genosensing [26,27], studies of corrosion [28] and other surface phenomena [29].…”

We report on a sensitive aptamer-antibody interaction-based assay for cytochrome c (Cyt c) using electrochemical impedance. 4-Amino benzoic acid is used for the oriented immobilization of aminated aptamers onto multi-walled carbon nanotubes on the surface of a screen-printed electrode via electrochemical grafting. Impedance was measured in a solution containing the redox system ferro/ferricyanide. The change in interfacial charge transfer resistance (R ct ) experienced by the redox marker was recorded to confirm the formation of a complex between aptamer and the target (Cyt c). A biotinylated antibody against cytochrome c was then used in a sandwich type of assay. The addition of streptavidin conjugated to gold nanoparticles and signal enhancement by treatment with silver led to a further increase in Rct. Under optimized conditions, a detection limit as low as 12 pM was obtained. Cross-reactivity against other serum proteins including fibrinogen, BSA and immunoglobulin G demonstrated improved selectivity.

“…Th is means that alternatives must be present at higher concentration, leading to the use of more soluble compounds and consequently encapsulation as a method of regulating the response to external or internal triggers (Table 1). Some success has also been achieved in increasing the solubility by replacing methyl groups in organic functionalities with hydroxyl groups [40].…”

Metals are used extensively in modern society in a range of applications from infrastructure to aircraft to consumer products. The protection of metals, primarily from corrosion, has been an active area of materials science for many years. However, over the last 20 years, changing regulations governing both environmental issues and human health have driven even greater activity in this fi eld. Addressing these regulatory changes presents some of the most exciting challenges in materials science. This review looks at current metal protection schemes, exploring the development of 'green' inhibitors and 'self-healing' paint fi lms that have inbuilt capacity to maintain functionality. Inorganic and organic materials science has undergone rapid development in recent decades and this review looks at how some of those developments, particularly in encapsulation and polymer healing, can be applied to the design of new protective paint systems.

“…Therefore, severe corrosion, scaling and fouling organisms adhesion problems are faced when seawater is used as industrial cooling water, and seawater does not conform to cycling cooling water quality requirements stipulated in the national standards "specification for design of industrial cycling cooling water treatment ". [10][11][12] More severe problems are faced when seawater is used as industrial cycling cooling water. On one hand, more severe corrosion, scaling and fouling organisms adhesion problems are faced, and seawater need to be filtered with strainer, seawater was delt with by adding seawater corrosion inhibitor, scale inhibitor dispersing agent, bacterium and algae biocide, etc.…”

Necessity, history, actuality, problems and countermeasures, industrial application prospect of seawater used as cycling cooling water are analysed. When seawater is used as cycling cooling water, waste water discharge quantity and intake quantity of water are small, engineering investment and operation cost are low, and it is more reasonable in economy. It is in favour of saving fresh water resources, easing tensions in industrial water, protecting marine environment of coastal areas, keeping ecological balance, but the corrosion, scaling and biological control problems in the system running, including salt deposition, salt fog splash, erosion, etc of the seawater cooling tower, should be solved well. Fresh water resources are short in our country, and seawater need be used as industrial cooling waterThe shortage crisis of fresh water resources has become increasingly worse, and the normal activities of human beings are under serious threat, with the rapid development of social economy, population growth and the increasing deterioration of the ecological environment. Our country is ranked as one of the 13 driest countries in the world by the United Nations, and lack of fresh water resources is one of the most serious resource problems in our country. China's coastline is 1.82*10 3 km, and dozens of coastal cities are rich in seawater resources. [1][2][3][4] According to statistics, about 80% of the urban water is industrial water, and about 80% of the industrial water is industrial cooling water. In coastal areas, fresh water resource is very limited, and allowable withdrawal is declining year after year. In coastal and island areas, seawater used as source of thermal power, nuclear power, petrochemical, chemical, metallurgical and other industries cooling water, not only can save fresh water, make the limited freshwater resources for maximum use, alleviate contradictory problem of the shortage of fresh water and the industrial development, but also is the important way to solve the shortage of water resources in our country industry, will produce remarkable economic benefit and social benefit. At present, a batch of seawater cooling thermal power plants, nuclear power plants have been set up in China's coastal areas. [4][5][6][7][8][9] The history and status quo of seawater used as industrial cooling water Cooling ways include once-through cooling and cycling cooling when water is used as industrial cooling water.Once-through cooling using seawater is that seawater is discharged directly after it is pumped through simple grid filters and into the condensers or other heat exchange equipments. At present, the cooling way is adopting by most of coastal thermal power plants, because it has a lot of advantages, including that seawater temperature is low and quite stable, seawater resources are rich, stable and reliable, cooling effect is good, operation and management is simple,...
