| 1 | Massively parallel direct writing of nanoapertures using multi-optical probes and super-resolution near-fields显示文摘Laser direct-writing enables micro and nanoscale patterning,and is thus widely used for cutting-edge research and industrial applications.Various nanolithography methods,such as near-field,plasmonic,and scanning-probe lithography,are gaining increasing attention because they enable fabrication of high-resolution nanopatterns that are much smaller than the wavelength of light.However,conventional methods are limited by low throughput and scalability,and tend to use electron beams or focused-ion beams to create nanostructures.In this study,we developed a procedure for massively parallel direct writing of nanoapertures using a multi-optical probe system and superresolution near-fields.A glass micro-Fresnel zone plate array,which is an ultra-precision far-field optical system,was designed and fabricated as the multi-optical probe system.As a chalcogenide phase-change material(PCM),multiple layers of Sb_(65)Se_(35) were used to generate the super-resolution near-field effect.A nanoaperture was fabricated through direct laser writing on a large-area(200×200mm^(2))multi-layered PCM.A photoresist nanopattern was fabricated on an 8-inch wafer via near-field nanolithography using the developed nanoaperture and an i-line commercial exposure system.Unlike other methods,this technique allows high-throughput large-area nanolithography and overcomes the gap-control issue between the probe array and the patterning surface. | Changsu Park Soobin Hwang Donghyun Kim Nahyun Won Runjia Han Seonghyeon Jeon Wooyoung Shim Jiseok Lim Chulmin Joo Shinill Kang | 2022 | Microsystems & Nanoengineering2022，8，5： | 0 |
| 2 | Effects of homogenization and heat treatment on fatty acids in milk from five dairy species显示文摘Milk fatty acids significantly contribute to human nutrition and clinical health.However,previous evidence for changes in the fatty acid profiles of different dairy species following homogenization and heat treatment is lacking.Here,changes in fat globule particle size and fatty acids in samples of Holstein,goat,buffalo,yak,and camel milk following homogenization(20 MPa)and heat treatment(63℃for 30 min and 90℃for 15 min)were investigated using a laser particle sizer and gas chromatography approach.The results indicated that the milk fat globule particle size of all studied dairy species significantly decreased after homogenization and heat treatment,in which there was no difference.The fatty acid composition of C10:0 and medium-chain fatty acid in goat milk,Ci8:0 and long-chain fatty acid in camel milk,and C16:0 in buffalo and yak milk served as the characteristic traits of these milks.Changes in the relative contents of several fatty acids(C4:0,C10:0,C16:0,C18:0,C18:1n9c,and C18:3n3)were dependent on homogenization,heat treatment,and the type of dairy species.In particular,C18:3n3 significantly decreased in goat and camel milk after homogenization and heat treatment.These findings provide new insights into how homogenization and heat treatment affect the fatty acid profile and can be used to further improve the heat treatment of milk from minor dairy species. | Rongbo Fani Runjia Shi Zhongyuan Ji Qijing Du Jun Wang Hongning Jiang Rongwei Han Yongxin Yang | 2023 | Food Quality and Safety2023，7，1： | 0 |
