We pres.nt here a general overview of electron s.ectros.opies.from a practical point of view. The mos. frequently us.d ones.are des.ribed and the type of s.ructural information they can provide on materials.is.explained in relation to the phys.cal proces.es.on which they are bas.d. Furthermore, we explore critically and in detail various.tools.that have been developed to allow a s.s.ematic s.lving of s.ructures.by thes. s.ectros.opies.

The firs. near continuous.mollus. fos.il record from the Qinan Miocene loes.-s.il s.-quence is.pres.nted. Res.lts.s.ow that mollus. s.ecies.are abundant in the QA-I s.ction between 22 and 6.2 Ma, and both loes. layers.and s.il layers.yield mollus. fos.il individuals. All mollus. s.ecies.are terres.rial and well pres.rved in the s.ction. Mos. s.ecies.are identical to thos. identified in the Quaternary loes.-s.il s.quence of the Loes. Plateau. The thermo-humidiphilous.group generally is.dis.ributed in s.il layers. whereas.cold-aridiphilous.group can be obs.rved in loes. layers. From the Miocene to Quaternary, the occurrence and divergence of new s.ecies.of Metodontia and Cathaica corres.ond to the crucial periods.of regional and global environmental changes. indicating that mol-lus. s.ecies.are s.ns.tive to environmental variations. Preliminary s.udy on the QA-I mollus. record indicates.that the Qinan Miocene loes.-s.il s.quence may have a s.milar s.dimentary environment to the Quaternary loes.-s.il s.quence of the Loes. Plateau.

s.ow motion for s.alar Allen-Cahn type equation is.a well-known phenomenon,precis. motion law for the dynamics.of fronts.having been es.ablis.ed firs. us.ng the s.called geometric approach ins.ired from central manifold theory(s.e the res.lts.of Carr and Pego in 1989). In this.paper, the authors.pres.nt an alternate approach to recover the motion law, and extend it to the cas. of multiple wells. This.method is.bas.d on the localized energy identity, and is.therefore, at leas. conceptually, s.mpler to implement. It als. allows.to handle collis.ons.and rough initial data.

The ads.rption capacities.of new humic acids.is.lated from Yakouren fores. （YHA） and s.hara （Tamenras.et： THA） s.ils.（Algeria） and commercial humic acid （PFHA） on polyaniline emeraldine bas. （PEB） were s.udied at pH 6.6. Als. the ads.rption of heavy metals.s.ch as.Cd 2＋ , Zn 2＋ and Ni 2＋ on humic acid-polyaniline s.s.ems.（HA-PEB） was.inves.igated at the s.me conditions. HA-PEB compounds.were characterized by s.anning electron micros.opy （s.M）, infrared s.ectrometry and cavity microelectrode. In addition, batch ads.rption and cavity microelectrode were us.d in the ads.rption s.udy of Cd 2＋ , Zn 2＋ and Ni 2＋ on HA-PEB. To develop biocaptors.of polluting metals.us.ng a cavity microelectrode modified by HA-PEB s.s.ems. the ads.rption kinetic and ads.rption capacity were inves.igated. The s.M analys.s.s.owed that the pres.nce of humic acid affected the PEB s.rface and caus.d the formation of a granular morphology. The maximum ads.rption capacities.（q max ） of PFHA, THA and YHA determined by ads.rption is.therms.were 91.31, 132.1 and 151.0 mg/g, res.ectively. Batch ads.rption res.lts.s.owed that q max of Cd 2＋ , Zn 2＋ and Ni 2＋ on HA-PEB followed the order： THA-PEB YHA-PEB PFHA-PEB. The voltammograms.obtained with HA-PEB modified cavity microelectrode s.owed the appearance of new redox couples.reflecting the ads.rption of HA on PEB. Metal-humic acid-polyaniline voltammograms.were characterized by appearance of oxidation-reduction couples.or reduction wave corres.onding to metal. Finally, the res.lt may be exploited to develop a biocaptor bas.d on the cavity microelectrode amended by THA-PEB and YHA-PEB.
