Tailored silver grid as transparent electrodes directly written by femtosecond laser

Applied Physics Letters (2016)

Yuanyuan Zhao Mei‐Ling Zheng Xian-Zi Dong Feng Jin Jie Liu

We present the design and realization of silver grid transparent electrodes (SGTEs) easily fabricated by femtosecond laser direct writing of silver aqueous solution. The fabricated SGTEs with a sheet resistance down to 47 Ω/□ and optical transmittance up to 93% are demonstrated. These sheet resistance and transmittance values are comparable to commercially available indium tin oxide. High uniform morphology of the directly written SGTEs results in the ultra-stable tailored performance parameter at electronic and optical fields. The sheet resistance and transmittance can be tailored precisely by manipulating the filling fraction of the uniform SGTEs. This study provides an approach for creating SGTEs in a controllable fashion, and the SGTEs exhibit high transmittance and low sheet resistance, which could open up new avenues towards widespread application in electronics, photovoltaics, and optoelectronics.

Investigation of the effect of polar components in cream on the flavor of heated cream based on NMR and GC-MS methods

LWT (2021)

Tingting Ye Jie Liu Peng Wan Si-Yi Liu Qin‐Zhi Wang

Cream is usually used during baking and contributes a pleasant aroma to the baked foods, but the effect of its polar components on the cream flavor is not fully understood. In this study, the polar components were extracted by using ethanol, and then were analyzed by 1H nuclear magnetic resonance (NMR). The main compositions in the extraction were lactose, phospholipids, free amino acids and free fatty acids. Then all the samples were baked at 160 °C for 30 min, respectively. GC-MS analysis showed that the polar components could generate lots of odorants, and with the addition of polar components, the lipid-derived volatile compounds in cream were significantly increased and varied, as well as Maillard reaction and caramelization products, especially butanoic acid, hexanal, (E,E)-2,4-decadienal, furfural, furaneol, maltol, methylpyrazine, 2,3-dimethylpyrazine, 2-methyl and 3-methylbutanal. On the contrary, the ethanol-treated cream sample had less odorants. Sensory analysis confirmed that the caramel and roasted notes were significantly enhanced with the addition of polar components, the ethanol-treated cream and polar components sample was similar to the cream in the attributes of milk, sweet and buttery. These data indicated that polar components in cream could be used as a functional flavor enhancer.

Y. Oka Yuki Ishiwatari Jie Liu Takayuki Terai Shinya Nagasaki

Research program of a supercritical-pressure light water cooled fast reactor (Super Fast Reactor) is funded by MEXT (Ministry of Education, Culture, Sports, Science and Technology) in December 2005 as one of the research programs of Japanese NERI (Nuclear Energy Research Initiative). It consists of three programs. (1) development of Super Fast Reactor concept; (2) thermal-hydraulic experiments; (3) material developments. The purpose of the concept development is to pursue the advantage of high power density of fast reactor over thermal reactors to achieve economic competitiveness of fast reactor for its deployment without waiting for exhausting uranium resources. Design goal is not breeding, but maximizing reactor power by using plutonium from spent LWR fuel. MOX will be the fuel of the Super Fast Reactor. Thermal-hydraulic experiments will be conducted with HCFC22 (Hydro chlorofluorocarbons) heat transfer loop of Kyushu University and supercritical water loop at JAEA. Heat transfer data including effect of grid spacers will be taken. The critical flow and condensation of supercritical fluid will be studied. The materials research includes the development and testing of austenitic stainless steel cladding from the experience of PNC1520 for LMFBR. Material for thermal insulation will be tested. SCWR (Supercritical-Water Cooled Reactor) of GIF (Generation-4 Internationalmore » Forum) includes both thermal and fast reactors. The research of the Super Fast Reactor will enhance SCWR research and the data base. The research period will be until March 2010. (authors)« less

Bioorthogonal SERS Nanoprobes for Mulitplex Spectroscopic Detection, Tumor Cell Targeting, and Tissue Imaging

Chemistry - A European Journal (2015)

Junzhou Wu Duanwei Liang Qingqing Jin Jie Liu Mei‐Ling Zheng

A surface-enhanced Raman scattering (SERS) technique shows extraordinary features for a range of biological and biomedical applications. Herein, a series of novel bioorthogonal SERS nanoprobes were constructed with Gold nanoflower (AuNF) and Raman reporters, the signals of which were located in a Raman-silent region of biological samples. AS1411 aptamer was also co-conjugated with AuNF through a self-assembled monolayer coverage strategy. Multiplex SERS imaging using these nanoprobes with three different bioorthogonal small-molecule Raman reporters is successfully achieved with high multiplexing capacity in a biologically Raman-silent region. These Raman nanoprobes co-conjugated with AS1411 showed high affinity for tumor cells with overexpressed nucleolin and can be used for selective tumor cell screening and tissue imaging.

Protein-Based 3D Microstructures with Controllable Morphology and pH-Responsive Properties

ACS Applied Materials & Interfaces (2017)

Shuxin Wei Jie Liu Yuanyuan Zhao Tingbin Zhang Mei‐Ling Zheng

The microtechnology of controlling stimuli-responsive biomaterials at micrometer scale is crucial for biomedical applications. Here, we report bovine serum albumin (BSA)-based three-dimensional (3D) microstructures with tunable surface morphology and pH-responsive properties via two-photon polymerization microfabrication technology. The laser processing parameters, including laser power, scanning speed, and layer distance, are optimized for the fabrication of well-defined 3D BSA microstructures. The tunable morphology of BSA microstructures and a wide range of pH response corresponding to the swelling ratio of 1.08-2.71 have been achieved. The swelling behavior of the microstructures can be strongly influenced by the concentration of BSA precursor, which has been illustrated by a reasonable mechanism. A panda face-shaped BSA microrelief with reversible pH-responsive properties is fabricated and exhibits unique "facial expression" variations in pH cycle. We further design a mesh sieve-shaped microstructure as a functional device for promising microparticle separation. The pore sizes of microstructures can be tuned by changing the pH values. Therefore, such protein-based microstructures with controllable morphology and pH-responsive properties have potential applications especially in biomedicine and biosensors.

Dynamic Color‐Switching of Hydrogel Micropillar Array under Ethanol Vapor for Optical Encryption

Small (2023)

Ming‐Xia Zhou Feng Jin Jianyu Wang Xian‐Zi Dong Jie Liu

Responsive structural colors from artificially engineered micro/nanostructures are critical to the development of anti-counterfeiting, optical encryption, and intelligent display. Herein, the responsive structural color of hydrogel micropillar array is demonstrated under the external stimulus of ethanol vapor. Micropillar arrays with full color are fabricated via femtosecond laser direct writing by controlling the height and diameter of the micropillars according to the FDTD simulation. Color-switching of the micropillar arrays is achieved in <1 s due to the formation of liquid film among micropillars. More importantly, the structural color blueshift of the micropillar arrays is sensitive to the micropillar diameter, instead of the micropillar height. The micropillar array with a diameter of 772 nm takes 400 ms to complete blueshift under ethanol vapor, while that with a diameter of 522 nm blueshifts at 2400 ms. Microscale patterns are realized by employing the size-dependent color-switching of designed micropillar arrays under ethanol vapor. Moreover, Morse code and directional blueshift of structural colors are realized in the micropillar arrays. The advantages of controllable color-switching of the hydrogel micropillar array would be prospective in the areas of optical encryption, dynamic display, and anti-counterfeiting.

Plasmon-enhanced nanosoldering of silver nanoparticles for high-conductive nanowires electrodes

Opto-Electronic Advances (2021)

Yuanyuan Zhao Xue-Liang Ren Mei‐Ling Zheng Feng Jin Jie Liu

The silver nanowires (Ag NWs) electrodes, which consist of incompact Ag nanoparticles (NPs) formed by multi-photon photoreduction, usually have poor conductivities. An effective strategy for enhancing conductivity of the Ag NWs electrodes is plasmon-enhanced nanosoldering (PLNS) by laser irradiation. Here, plasmon-enhanced photothermal effect is used to locally solder Ag NPs and then aggregates of these NPs grow into large irregular particles in PLNS process. Finite element method (FEM) simulations indicate that the soldering process is triggered by localized surface plasmon-induced electric field enhancement at “hot-spots”. The effectiveness of PLNS for enhancing conductivity depends on laser power density and irradiation time. By optimizing the conditions of PLNS, the electrical conductivity of Ag NWs is significantly enhanced and the conductivity σ_s is increased to 2.45×10⁷ S/m, which is about 39% of the bulk Ag. This PLNS of Ag NWs provides an efficient and cost-effective technique to rapidly produce large-area metal nanowire electrodes and capacitors with high conductivity, excellent uniformity, and good flexibility.
