- Effect of Fabricating Parameters on Morphology and Photocatalytic Performance of CdS NCs/TiO2 NTs Photoelectrode for Decomposition of Organic Pollutants
Xiuwen Cheng, Guoping Pan and Xiujuan Yu
Article first published online: 27 APR 2015 | DOI: 10.1002/adem.201500049
In this study, CdS NCs/TiO2 NTs photoelectrode is fabricated through anodization, followed by electrodeposition strategy. Meanwhile, some critical parameters are optimized through morphologies observation and PC decomposition of rhodamine B (RhB). Results show that the influence of fabricating parameters for degradation of RhB aqueous solution fitted well with the pseudo-first-order kinetics function.
- Solid-State Foaming by Oxide Reduction and Expansion: Tailoring the Foamed Metal Microstructure in the Cu–CuO System with Oxide Content and Annealing Conditions
Mark A. Atwater, Kris A. Darling and Mark A. Tschopp

Copper foam is created by the reduction of a ball-milled Cu–CuO composite. Final density is dependent on time and temperature, but very small pore and grain sizes are achieved under all processing conditions. This presents unique implications for creating tailored foam structures in loose powder as well as in bulk parts created via powder metallurgy.
- Dynamic Behavior of Vertically Aligned Carbon Nanotube Foams With Patterned Microstructure

Micropatterned VACNT foams are fabricated to investigate the relationship between the structure and the bulk dynamic response. Changes in the patterns' geometry allow tuning the specific energy absorption of VACNTs under impact loading, and result in materials with significantly reduced bulk density. The study confirms that patterned VACNT foams hold great potential as novel lightweight material for impact protection.
- Cushioning and Energy Absorbing Property of Combined Aluminum Honeycomb
Yu-Liang Lin, Zhi-Feng Zhang, Rong Chen, Yan Li, Xue-Jun Wen and Fang-Yun Lu

Out-of-plane crushing behavior of combined aluminum honeycomb sample is investigated. Inserting processes between different honeycombs smooth the stress curve and lower the stress level, which is beneficial to the optimization design of aluminum honeycomb buffer.
- Production of Clad Steel Strips by Twin-Roll Strip Casting
Michele Vidoni, Rebecca Ackermann, Silvia Richter and Gerhard Hirt
Article first published online: 22 APR 2015 | DOI: 10.1002/adem.201500094
Cladding by twin-roll strip casting of a combination of the austenitic stainless steel 1.4301 and the carbon steel 1.1248 was investigated. This production method is based on the introduction of a solid strip between the casting rolls, where the joining takes place. For the first time this process is used to combine two steel alloys. Shear tests with an optimized shearing surface are used to measure the mechanical resistance of the clad joint.
