As shown in article number 2002133 by Rong-Ming Ho and co-workers, gold nanohelices for chiral plasmonic polymer films can be fabricated using self-assembled block copolymers as templates templated electroless plating. The nanohelix serve absorber scatterer the polymeric manipulating circular-polarized light based on its chirality. This bottom-up approach suggests a facile method fabrication of...

We studied the effects of catalyst introduction methods using poly(amidoamine) (PAMAM) dendrimers on the nickel patterning of polyelectrolyte multilayer (PEM)-coated substrates. Three different approaches to palladium catalyst introduction using microcontact printing as the patterning technique were utilized and compared. The catalyst introduction methods are (1) direct catalyst stamping, (2) d...

Among various lead-free alloys, Sn-Ag(-Cu) system solders are considered the most promising lead-free solders for both wave and reflow soldering technology. Moreover, to improve the characteristics of lead-free solders, the effect of the addition of minor elements to lead-free solders on the properties of solder and interfacial reactions have been studied. The purpose of this research was to in...

Magnesium-based bulk metallic glass matrix composites (BMGMCs) have better plasticity than the corresponding bulk metallic glasses (BMGs); however, their strength and density are often compromised due to the fact that the effective reinforcement phase is mostly plastic heavy metal. For lightweight SiC-particle reinforced BMGMCs, interface wettability and the sharpness of the particles often red...

A novel technique for obtaining nonanomalous Ni-Zn-P coatings with high Ni content ~74 wt % as compared to 15-20 wt % in the conventional plating method! has been developed. These coatings show promise as a replacement for Cd in sacrificially protecting steel. Ni-Zn-P coatings were deposited using an electroless method from a solution containing NiSO4 , complexing agent and ammonium chloride. V...

Novel nickel-based microlattice materials with structural hierarchy spanning three different length scales (nm, lm, mm) are characterized microstructurally and mechanically. These materials are produced by plating a sacrificial template obtained by self-propagating photopolymer waveguide prototyping. Ni–P films with a thickness of 120 nm to 3 lm are deposited by electroless plating, whereas thi...
