Some technological implications of optical brighteners addition in gelatin systems have been investigated: a) the effect on viscosity as a consequence of ionic strength influence; b) the impact on the kinetics of the hardening process, quantifying the size of the rate constant for the cross-linking reaction of gelatin with a slow acting hardener (pseudo first order reaction), by measuring the reduction of swelling for the coated layers. Variations of the rate constant are given in relation to: optical brighteners' concentration optical brighteners' type (disulphoaminostilbene or dichloraminostilbene) gelatin type (limed bone or acid bone) The experimental results have confirmed the structure-breaking action of optical brighteners in the gelatin network.","PeriodicalId":149069,"journal":{"name":"Journal of The Society of Photographic Science and Technology of Japan","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115486961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different kinds of the substituents(phenyl, p-tolyl and m-tolyl)with and without the orientation of the main chains are examined. It is found that the trapped carriers are released at some specific temperatures exhibiting the endothermic motion of polysilanes but cannot be released completely in one scan of the measurement. This behavior has been analyzed by introducing a concept of the temperature-dependent lifetime of trapped carriers. It is considered that the aromatic substituents in polysilanes form π-π states to be trapping centers for holes and the trapped holes are released by the endothermic motions of the substituents. The analysis reveals that 1)the substituents examined have two principal holereIease peaks at 215K-219K and 226K-234K, 2)the orientation broadens the peak widths, and 3)the orientation also shifts the peaks to higher temperatures for polysilanes with phenyl and p-tolyl but not for polysilanes with m-tolyl because of its strong steric hindrance.","PeriodicalId":149069,"journal":{"name":"Journal of The Society of Photographic Science and Technology of Japan","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129160237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Self-adapting systems are proposed as potential solutions. Such systems perform spectral content analysis on an encountered scene, reacting to the analysis by configuring efficient high quality spectral reconstruction. An experiment is reported comparing scene-derived spectral estimation transforms to static global transforms in multi-channel imaging simulations. For noise-free simulations, the adaptive approach showed clear benefit in terms of colorimetric and spectral statistics. When noise was added, the adaptive method continued to be superior in terms of spectral evaluations, but colorimetric degradation for the adaptive approach exceeded that of the static. This provided additional evidence that spectral reconstruction methods should reference psychometrics as an integral part of spectral error management.","PeriodicalId":149069,"journal":{"name":"Journal of The Society of Photographic Science and Technology of Japan","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115960001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The in-situ time-resolved absorption spectra of the J-aggregate provided direct spectroscopic evidence for the reversible J-aggregate oxidation and a convenient way to monitor the oxidized mole fraction in the J-aggregate in real time. The potential step method enabled us to observe the reversible redox equilibrium of the layered J-aggregate. The experimental data were analyzed in the framework of the ideal Nernst equation to extract the standard potential for the J-aggregate oxidation and to examine the extent of non-ideality caused at higher oxidation levels due to the repulsive interactions between dye positive holes. The standard potential for the J-aggregate oxidation in the model system was substantially more negative than that known for the monomer by —0.14V. Implications of the results for spectral sensitization phenomena are also discussed.","PeriodicalId":149069,"journal":{"name":"Journal of The Society of Photographic Science and Technology of Japan","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122710652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have fabricated field emitters using carbon nanocoils with different diameters and lengths. The field emission measurement shows that the turn-on voltages of carbon nanocoil field emitters are dependent on the diameters of the coiled tubules. Decreasing the thickness of iron film and the flow rate of acetylene gas can decrease the average diameter of grown carbon nanocoils. Decreasing the growth time can obviously decrease the average length of the coils. It is expected to use carbon nanocoils with small diameter and short length to fabricate high performance flat panel display, which is driven at low voltage and has high resolution and brightness.","PeriodicalId":149069,"journal":{"name":"Journal of The Society of Photographic Science and Technology of Japan","volume":"154 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123447109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
