- Fabricating Three-Dimensional Periodic Micro Patterns on Photo-Resists Using Laser Interference Lithography
Florian Rößler, Valentin Lang, Denise Günther and Andrés Fabián Lasagni
Version of Record online: 21 FEB 2017 | DOI: 10.1002/adem.201600855
Mushroom geometries as in the springtails have demonstrated to show outstanding surface functionalities such as non-wetting and prevention of bacterial settlement. This study focus on the development of a laser-based fabrication method to produce three-dimensional periodic patterns with undercuts irradiating a multilayered system of SU-8 and LOR using interference patterns.
- Microstructure, Texture, and Mechanical Properties of Alternate α/β Mg–Li Composite Sheets Prepared by Accumulative Roll Bonding
Feng Zhong, Tianzi Wang, Ruizhi Wu, Legan Hou, Jinghuai Zhang, Xinlin Li, Milin Zhang, Anping Dong and Baode Sun
Version of Record online: 20 FEB 2017 | DOI: 10.1002/adem.201600817
Mg–5Li–1Al sheet and Mg–12Li–1Al sheet are used to prepare α/β Mg–Li composite sheets with accumulative roll bonding. The microstructure of the specimens is investigated. The texture and mechanical properties are improved. In the interface areas between sheets, a cross shear zone exists.
- The Effect of Pressure Stress on the Evolution of B2(ω) Phase in High Nb Containing TiAl Alloy
Bei Cao, Jieren Yang, Xuyang Wang and Rui Hu
Version of Record online: 20 FEB 2017 | DOI: 10.1002/adem.201600844
The B2 phase is unstable at 850 °C and transfers to ω phase in high Nb–TiAl alloy, which can be promoted by press pressure. The ω fraction further increases to 65.2% under 500 MPa after 1 h. Also, pressure can suppress the transition of ω B2 at 900 °C. The ω phase remains in B2 area as 34.1 vol% content under 300 MPa after 1 h.
- High-Quality Epitaxial MgB2 Josephson Junctions Grown by Molecular Beam Epitaxy
Lin Li, Hui Zhang, Yi-Hang Yang and Guo-Xing Miao
Version of Record online: 20 FEB 2017 | DOI: 10.1002/adem.201600792
Epitaxial MgB2 films are grown with molecular beam epitaxy (MBE) and optimized with the assistance of in situ reflection high-energy electron diffraction (RHEED). Hetero-epitaxial (0001)-MgB2/(111)-MgO/(0001)-MgB2 stacks are deposited and fabricated into micro Josephson junctions, which reveal clear Fraunhofer patterns and Fiske steps, indicating superb materials quality.
- Metamaterial Based Passive Wireless Temperature Sensor
Hasanul Karim, Diego Delfin, Luis A. Chavez, Luis Delfin, Ricardo Martinez, Jose Avila, Carlos Rodriguez, Raymond C. Rumpf, Norman Love and Yirong Lin
Version of Record online: 14 FEB 2017 | DOI: 10.1002/adem.201600741
A metamaterial-based passive wireless temperature sensor is presented. Boron Nitride and Barium Titanate were the ceramic materials used for the matrix, with embedded Copper rings acting as closed ring resonators. The feasibility of wireless temperature sensing is demonstrated up to 200 °C. An average sensitivity of 0.462 MHz °C was achieved.
