Abstract: Described herein are systems and methods for performing a surface mechanical attrition treatment (SMAT) to the surface of a variety of materials including thin films, nanomaterials, and other delicate and brittle materials. In an aspect, a surface of a material is modified to a modified surface and from an original state to a modified state, wherein the modified state comprises a physical modification, a chemical modification, or a biological modification. In another aspect, a surface mechanical attrition treatment (SMAT) is applied to the modified surface of the material for a defined duration of time, wherein a condition associated with the SMAT is adjusted based on a structural composition of the material. In yet another aspect, a defined strain is imposed on the structural composition of the material based on the SMAT.

Abstract: A nanoporous metal structure is made by etching a metal alloy structure of two or more metals. Less than all of the metals are selectively removed (e.g., dissolved in solution) from the alloy in the presence of an alternating voltage profile, for example, a periodic voltage profile. The resulting nanoporous metal structure, having pore openings of about 20 nm to about 500 nm in diameter and a purity of at least about 70%, can be further treated to alter some or all of the structure, and/or to add, remove and/or modify properties thereof.

Abstract: The invention discloses a wastewater processing method of hydrolysis-acidification enhanced by addition of zero-valent iron (ZVI), including the following steps: 3˜6 ZVI-filling layers are settled in the middle of an anaerobic hydrolysis-acidification reactor. Excess sludge taken from sewage treatment plant using as seed sludge is added into this anaerobic hydrolysis-acidification reactor for startup and domestication. In the present invention, ZVI are added into this anaerobic hydrolysis-acidification reactor to accelerate organic matters degradation and produce more acetic acids, accompanied with higher COD removal obtained. ZVI can be protected from rust in this anaerobic biological environment due to the air isolation. Also, ZVI can enhance anaerobic hydrolysis of wastewater through reducing refractory pollutants involved in wastewaters.
