TL;DR: In this article, a method of patterning a material surface is provided in which an elastomeric stamp having a stamping surface is coated with a self-assembled monolayer forming species having a functional group selected to bind to a particular material.
Abstract: A method of patterning a material surface is provided in which an elastomeric stamp having a stamping surface is coated with a self-assembled monolayer forming species having a functional group selected to bind to a particular material, and the stamping surface is placed against a surface of material and is removed to leave a self-assembled monolayer of the species according to the stamping surface pattern of the stamp. Additional stamping steps may be subsequently effected to produce any of a variety of SAM patterns on the surface. Additionally, portions of the material surface that are not coated with a stamped SAM pattern may be filled in with another SAM-forming species. Alternately, portions that are not covered by a SAM layer may be etched or plated. Additionally, an optical switch and other optical devices and elements are provided, comprising articles similar to the inventive stamp.

TL;DR: In this article, a scalable, low-cost stamping strategy was used to produce flexible all-MXene MSCs with controlled architectures, which can be easily scaled up by designing pad or cylindrical stamps, followed by a cold rolling process.
Abstract: The fast growth of portable smart electronics and internet of things have greatly stimulated the demand for miniaturized energy storage devices. Micro-supercapacitors (MSCs), which can provide high power density and a long lifetime, are ideal stand-alone power sources for smart microelectronics. However, relatively few MSCs exhibit both high areal and volumetric capacitance. Here rapid production of flexible MSCs is demonstrated through a scalable, low-cost stamping strategy. Combining 3D-printed stamps with arbitrary shapes and 2D titanium carbide or carbonitride inks (Ti3C2Tx and Ti3CNTx, respectively, known as MXenes), flexible all-MXene MSCs with controlled architectures are produced. The interdigitated Ti3C2Tx MSC exhibits high areal capacitance: 61 mF cm−2 at 25 μA cm−2 and 50 mF cm−2 as the current density increases by 32 fold. The Ti3C2Tx MSCs also showcase capacitive charge storage properties, good cycling lifetime, high energy and power densities, etc. The production of such high-performance Ti3C2Tx MSCs can be easily scaled up by designing pad or cylindrical stamps, followed by a cold rolling process. Collectively, the rapid, efficient production of flexible allMXene MSCs with state-of-the-art performance opens new exciting opportunities for future applications in wearable and portable electronics.

TL;DR: In this article, it is shown that the forming limit for both proportional loading and non-proportional loading can be explained from a single criterion which is based on the state of stress rather than the state-of-stress.
