Restructuring of plasmonic nanoparticle aggregates with arbitrary particle size distribution in pulsed laser fields

We have studied processes of interaction of pulsed laser radiation with resonant groups of plasmonic nanoparticles（resonant domains） in large colloidal nanoparticle aggregates having different interparticle gaps and particle size distributions.These processes are responsible for the origin of nonlinear optical effects and photochromic reactions in multiparticle aggregates.To describe photo-induced transformations in resonant domains and alterations in their absorption spectra remaining after the pulse action,we introduce the factor of spectral photomodification.Based on calculation of changes in thermodynamic,mechanical,and optical characteristics of the domains,the histograms of the spectrum photomodification factor have been obtained for various interparticle gaps,an average particle size,and the degree of polydispersity.Variations in spectra have been analyzed depending on the intensity of laser radiation and various combinations of size characteristics of domains.The obtained results can be used to predict manifestation of photochromic effects in composite materials containing different plasmonic nanoparticle aggregates in pulsed laser fields.

Some Novel Viewpoints on Physiology and Pathology of TCM Sphygmology

In Traditional Chinese Medicine(TCM),pulse manifestation are an essential method for clinicians to make accurate diagnosis while researches on pulse manifestation are also an important direction for the modernization of TCM.According to the viewpoints of TCM,the abnormality of qi,xue,yin and yang will lead to some alterations of pulse manifestations while by detecting these alterations of pulse manifestation,TCM researchers can not only conclude the abnormality of the qi,xue,yin and yang in the patients,make exact diagnose in TCM but also afford the just therapies.Our past researches had abstracted all metabolisms in our body into to pathways:energy metabolism which should be regarded as yang and stem cell proliferation&differentiation(SCPD)which should be regarded as yin.These two pathways support the metabolisms of local tissue and organs while arteries play vital roles for transportation of energy agents and stem cells to local tissue and organs.By detecting the alterations of pulse manifestations,clinician can conclude the alterations of energy metabolism and SCPD in body.Moreover,many novel parameters should be taken into consideration for describing the pulse manifestations and uncovering the physiology and pathology of pulse manifestations.
