The mechanical properties of metals, such as hardness, ability to resist repeated stressing (fatigue strength), ductility, and malleability, are often attributed to defects or imperfections in their crystal structure. The absence of a layer of atoms in its densely packed structure, for example, ena...

Figure 1. The main mechanisms of bacterial inactivation by metals. Different colored arrows are used to distinguish each mechanism. To date, metallic materials with proven antiviral capability are mainly composed of noble metal elements (e.g., gold and silver) and transition metal elements (e.g....
13, 1970 with the release of Black Sabbath's classic self-titled debut record. The omnipresent darkness and heaviness felt so far removed from the popular hard rock of the time, ushering in a new era of music. However, Sabbath's riff-driven style would later catch on within the doom and...
with control exmperiment revealed that the coordinaion of H+, generated from water dissociation on the catalyst surface, at the Pt-O-Fe interface elongated the Pt-O bond and weakned the bonding strength accordingly. This strategy is general and can be extended to other catalysts systerm having...
agZW-UiO-67·MSA was reheated to 90 °C and then compressed into sheet with both faces attached to gold wires. Before test, sample was pre-heated at 60 °C under vacuum overnight. At each temperature point, the measurement was conducted repeatedly with an interval of half an hour ...
T of gold shows a saturation tendency. The polyvalent metals to the right of the noble metals in the periodic table all have comparatively small thermopower, within the range 3 μVK−1 to −2 μVK−1 at room temperature. Of these metals, lead is of a particular importance for ...
Briefly, Au nanoparticles (NSp) were synthesized with a diameter of 30–40 nm as core by a standard sodium citrate reduction method. Then freshly prepared aqueous solution of 1 mM (3-aminopropyl) trimethoxysilane (APS, Sigma Aldrich) was added to the gold sol under vigorous magnetic ...
