It is desirable for the photothermal conversion materials in the actuators to be downsized to the molecular scale. However, in conventional actuator materials using copolymer gels composed of thermosensitive and photothermal conversion molecule-coordinated monomers, the strong cross-linking of molecules in the networks impairs the actuator deformation. In this study, we fabricated soft actuators consisting of interpenetrating polymer network (IPN) gels to suppress the cross-linking of the thermosensitive networks. Nd3+ and Yb3+ were used as wavelength-selective photothermal conversion molecules at 808 and 980 nm. Hydrophobic acrylamide derivatives and sodium acrylate were used as the thermosensitive and lanthanoid-ion-coordinated polymers, respectively. The lanthanoid ion concentrations in the IPN gels were about 0.2 M, which is 6 times larger than those of previous gels. The temperature response of swelling degrees (wt%) of the lanthanoid-ion-coordinated IPN gels were three times larger than that of the previous gels. Sandwich structure actuators consisting of Nd3+ and Yb 3+ IPN gels bent selectively toward the Nd 3+ gel side under 808 nm irradiation and toward the Yb3+ gel side under 980 nm irradiation.","PeriodicalId":16626,"journal":{"name":"Journal of oleo science","volume":"74 2","pages":"165-171"},"PeriodicalIF":1.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143066170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Total phenol amounts of caper seed oils extracted by cold press, sonication and solvent systems were recorded as 0.10, 0.11 and 0.16 mg GAE/100 g, respectively. There was no statistically significant differences between the total phenol values of caper seed oils provided by sonication and cold press systems (p > 0.05). While the flavonoid amount of the oil extracted from caper seeds by solvent extraction system is determined as 358.9 mg CE/100 g, the total flavonoid amounts of caper seed oils extracted by sonication and cold pressing methods were established as 194.6 and 83.9 mgCE/100 g, respectively. The highest antioxidant capacity was established in the oil provided by solvent extraction (1.456%), followed by ultrasonic extraction (1.453%) and cold press oil (1.448%) in decreasing order. The dominant phenolic components of caper seed oils were quercetin, kaempferol, gallic acid, resveratrol and catechin. The fatty acid detected at the highest value in caper oils extracted by different extraction systems was linoleic acid (61.16-62.74%), followed by oleic, palmitic and stearic acids in decreasing order. Other fatty acids were recorded at low levels. As a result, it can be said that the caper oil extracted by solvent extraction is richer in quercetin and linoleic acid.","PeriodicalId":16626,"journal":{"name":"Journal of oleo science","volume":"74 2","pages":"139-146"},"PeriodicalIF":1.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143066094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the mechanisms underlying these diverse and delicate tactile sensations are poorly understood. We developed a \"biomimetic tactile sensing system\" to reproduce the interfacial phenomena that occur on the skin surfaces and evaluated the \"moist\" and \"dry\" sensations of surface-treated cosmetic powders and the texture of organogel and dispersion formulations. This tactile sensing system consists of a finger model contact probe that mimics the fingerprint and mechanical properties of a human finger and a sinusoidal motion friction evaluation device that can reproduce natural and smooth motions. The finger model contact probe, which mimics the fingerprint and mechanical properties of a human finger, was designed such that the elastic modulus, which reflects hardness, and the surface energy, which affects adhesion, were comparable to those of human skin. In addition, grooves of hundreds of micrometers were engraved to imitate fingerprints. A scotch yoke mechanism that converts elliptical motion into sinusoidal motion was introduced into a sinusoidal motion friction evaluation device to reproduce natural and smooth motions. We analyzed the relationship between sensory evaluation and friction data for cosmetics and cosmetic ingredients and constructed a physical model of tactile sensation evocation. For example, the \"moistness\" of cosmetic powder was strongly felt when the friction coefficient in the sliding process was low, and a gap existed where the frictional force reached its maximum value. Commercially available makeup cosmetics and sunscreens were characterized based on their friction dynamics and classified accordingly. The wax derived from rice bran and rice paraffin was shown to have high oil-gelling ability, and the resulting gel was smooth to the touch, indicating that it is suitable as a raw material for lipstick and cleansing products.","PeriodicalId":16626,"journal":{"name":"Journal of oleo science","volume":"74 3","pages":"233-240"},"PeriodicalIF":1.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143537217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This collaborative study was organized by the Alternative Gas for the GC Subcommittee of the Japan Oil Chemists' Society and was evaluated by analyzing a standard mixture of fatty acid methyl esters (Supelco 37 Component FAME Mix), soybean, and sardine oils. On a 50% cyanopropyl siloxane capillary column, the resolution of 37 FAME mixtures using He, H2, or N2 gas was greater than 1.0. For the area% of the 37 FAME mixtures, the reproducibility relative standard deviations ranged from 0.59 to 4.72% for He gas, 0.39 to 4.96% for H2 gas, and 0.60 to 4.91% for N2 gas. No significant difference was observed in the area% for the 37 FAME mixtures among the three carrier gases. Furthermore, no significant differences in the percentages of major fatty acids in the soybean and sardine oils were detected between the different carrier gases. This study also determined that the analysis time was prolonged when N2 gas was used compared to when H2 or He gas was used. However, a cyanopropyl siloxane capillary column for fast and selective separation could improve the analysis time using N2 gas. Therefore, we conclude that the present method using H2 or N2 gas qualifies as a tentative official method of the Japan Oil Chemists' Society.","PeriodicalId":16626,"journal":{"name":"Journal of oleo science","volume":"74 4","pages":"349-360"},"PeriodicalIF":1.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143772719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
