Direct Ink Writing (DIW) has demonstrated great potential as a versatile method to 3D print multifunctional structures. In this work, we report the implementation of hydrogel meta-structures using DIW at room temperature, which seamlessly integrate large specific surface areas, interconnected porous characteristics, mechanical toughness, biocompatibility, and water absorption retention capabilities. Robust but hydrophobic polymers weakly crosslinked nature-origin hydrogels form balance in...

In this paper, the expressway engineering case along west bank of Qinghai Lake is taken as research background, and typical “aquatic grassland” silt on object. Through geotechnical test, wet‐dry cycle direct shear influence moisture content strength its indexes are studied. The results show that index c φ unmodified first increase then decline with water content, optimal about 30%. values , remolded decrease wetting drying cycles. When cycles exceed 5 times, does not have much effect...

Based on the Silicon-based IPD(Integrated Passive Device) technology, an experiment IPD microstrips is presented. Some metal materials which are used in semiconductor press applied and optimized for 50Ω impedance matching better signal transmission. The carried by HFSS simulated software transmission status from DC-30GHz reason loss analysed. In this experiment, theory evidences choosing

Abstract Qinghai Province is the second largest meteorolites falling area in China. The samples are provided by Tianshi Cultural Development Co., Ltd., and numbered HYLYS-1, THYS-2, HTYS-3 SMDYS-4, results of density test 7.57g / cm 3 , 3.60 3.80/cm 3.19 respectively. Major elements include Al, Ti, Ni, Mg, Ca, Fe, K, etc. Trace Co, Ba, Te, Cd, Ce, Li, La, Nd, Sr, testing shows that resistivity low, which indicates there many metal minerals such as iron nickel, SMDYS-4 high, few minerals....
