Have spare batteries and a battery charger. A charger may take eight hours to recharge a battery. Use a camera feature that continuously displays the date on the screen this establishes without question when the scene was shot. You may wish also to photo a card with the operator s name. Plan the location of camera and subject ahead of time. Use a tripod. Multiple views arc best. Use some combination of a front view, a side view, a back view, stepladder views (a partial-plan view), overall views, and closeup views. Begin a scene with a full view (far shot, wide-angle view) and then zoom as desired. 

In the next version of SHMM the studied PET filaments were subjected to extension at a constant speed and constant temperatures in the same temperature range from 80 to 95 C. The structural characterizations of the studied fibers after the above described heat-mechanical treatments were realized using differential scanning calorimetry (DSC) and wide-angle X-ray scattering (WAXS) measurements.

There is no doubt that methods of adsorption of gases and vapors, overall, are used for the characterization of porosity in carbons. This is because die molecular-sized porosity responds to the presence of the similar-sized molecules of an adsorptive. Another effective, but much less used (because of the need for specialty equipment), approach is that of SAXS and SANS. These two approaches provide informations which, generally, are in agreement with adsorption methods described above, as well as additional informations. They are non-destructive approaches where the probes are photons of X-ray radiation and neutrons. SAXS involves scattering of photons at interfaces with pores and tends to be more diffuse (because electron density is not zero within pores) than the scattering of neutrons. The technique is quite different to wide-angle X-ray diffraction (XRD), a technique most suitable for crystalline materials. An in-depth review of this subject area of scattering phenomena is provided by Hoinkis (1997). 

Obviously, the properties of the electrolyte in Li-ion batteries are of crucial importance, and a few comprehensive general review articles have already been pubhshed on the subject [116, 117, 120, 133]. In this chapter, the recent advances and new trends in electrolyte research will be overviewed from a wide angle, with a focus on novel electrolytes and electrolyte additives for high-energy electrode materials. 

Perfluorosulfonated membranes have a microscopic phase-separated structure with hydrophobic regions and hydrophilic domain. Hydrophobic regions provide the mechanical support and hydrophilic ionic domains provide proton transport channel. Many morphological models for PFSA have been developed based on SAXS and wide-angle x-ray scattering (WAXS) experiments of the membranes. However, because of the random chemical structure of the PFSA copolymer, morphological variation with water content and complexity of coorganized crystalline and ionic domains, limited characteristic detail proved by the SAXS and WAXS experiments, the structure of the PFSl has been still subject of debate. Here, a brief description of seven membrane structure models is provided.
