Performance and applications

The practical capacity of all such batteries is also dependent on the temperature of operation and is found to drop very rapidly at temperatures below 0°C. 

As the system is thermodynamically unstable with respect to hydrogen and oxygen evolution, lead-acid cells are subject to self-discharge  

Corrosion of the positive grid can occur on charging and overcharging if the metal becomes exposed to the electrolyte. This leads to a progressive weakening of the plate structure and to an increase in the internal resistance of the cell. 

Three main types of battery will be briefly described SLI batteries, 

For vehicles used in rugged terrain, batteries with tubular positive plates are required. As discussed above, SLI batteries are sometimes supplied in a dry charged state, especially for markets where a long shelf life is needed.

The pitot-venturi flow element is capable of developing a pressure differential 5 to 10 times that of a standard pitot tube. This is accomplished by employing a pair of concentric venturi elements in place of the pitot probe. The low-pressure tap is connected to the throat of the inner venturi, which in turn discharges into the throat of the outer venturi. For a discussion of performance and application of this flow element, see Stoll, Trans. Am. Soc. Mech. Eng., 73, 963-969 (1951). 

Tribology performances and applications of ordered molecular films have been a long-standing research subject in SKLT, the workplace for the authors of this book. Hu and Luo [42] prepared SAMs of fluoroalkylsilane (FAS) and poly-fluorealkylmethacrylate (PFAM) on the magnetic head of computer hard disk drivers. Experiment results show that the molecular films greatly improve the performance of the... 

Having explained the evolution of the peptide controls concept, the remainder of this chapter will describe the technology for creating peptide controls and review the data regarding their performance and applicability to IHC laboratory testing controls. 

The performance and applicability of the levitated droplet liquid dye laser are challenged by droplet evaporation and bleaching of the laser dye. In order to minimize these effects, Azzouz et al.11 used a measurement scheme, where nominally identical droplets were loaded consecutively, and each droplet was at... 

There may be many other types of periodical vibrations for liquid disintegration or dispersion in various applications. The features, operation parameters, performance and applications of various experimental and commercially available ultrasonic and acoustic atomizers have been described and compared by Topp and EisenklamJ129 ... 

Very little work (relative to research of electrode materials and electrolytes) is directed toward characterizing and developing new separators. Similarly, not much attention has been given to separators in publications reviewing batteries.A number of reviews on the on cell fabrication, their performance, and application in real life have appeared in recent years, but none have discussed separators in detail. Recently a few reviews have been published in both English and Japanese which discuss different types of separators for various batteries. A detailed review of lead-acid and lithium-ion (li-ion) battery separators was published by Boehnstedt and Spot-nitz, respectively, in the Handbook of Battery Materials. Earlier Kinoshita et al. had done a survey of different types of membranes/separators used in different electrochemical systems, including batteries."... 

In addition to these principal requirements, there are further characteristics that affect the performance and applicability of analysers and detectors. The signal should depend as little as possible on the liquid flow-rate and temperature. With continuous monitors, the sensor should be selective for the test component. On the other hand, with chromatographic detectors, the sensor should respond to all eluted components with the same sensitivity. 

The use of fluorescent dyes in biological probes and sensors is covered in some detail in Chapter 3 (section 3.5.6). Because there are marked solvatochromic effects on the luminescent spectra of many fluorophores, this phenomenon is utilised to tune their performance and application in biological and other systems. 

A thorough discussion of cetane improver performance and applications can be found in CHAPTER 4. 

Major qualification tests consisting of a series of functional (static and dynamic) and environmental tests are conducted during the development phase. These tests depend upon the type of device, its performance and application, and functional... 

This chapter will discuss the main concepts associated with crystallization practice, and will describe the main types of equipment used nowadays, together with some indications of their performance and applicability. 

The FTIR is also useful in the identification of unknown solvents when performing trace analysis for residual solvents in bulks. The FTIR also must be looked upon as a complement to data collected by GC-MS. Reviews on the performance and application of the FTIR to various problems have been published [119,120]. Reviews on the use of the FTIR in combination with mass spectrometry have been published [121-123]. 

The manipulation of this bioreactor is generally performed in a laminar-flow cabinet, and is thus an open and risky operation. This is probably a characteristic that differentiates this bioreactor type from the other homogeneous bioreactors, where reliability of all seals and connections can be ensured through the use of direct steam. Also, the large number of connections using flexible tubing makes the operation of this type of bioreactor more complicated than that of other bioreactors of the same class. Currently, the performance and application potential of these bioreactors are under evaluation by the biotechnological community.

As the photochromic dithienylethenes have a series of useful performances and applications, various dithienylethenes have been so far prepared and their excellent properties have been studied. Dithienylethene, in combination with phthalocyanines and their analogs, is one of the most important types among these photochromic compounds.
