BACKGROUND English ivy (Hedera helix) is well known for its adhesive properties and climbing ability. Essential to its ability to adhere to vertical surfaces is the secretion of a nanocomposite adhesive containing spherical nanoparticles, 60-85 nm in diameter, produced exclusively by root hairs present on adventitious roots. These organic nanoparticles have shown promise in biomedical and cosme...

Understanding friction and wear at the nanoscale is important for many applications that involve nanoscale components sliding on a surface, such as nanolithography, nanometrology and nanomanufacturing. Defects, cracks and other phenomena that influence material strength and wear at macroscopic scales are less important at the nanoscale, which is why nanowires can, for example, show higher stren...

Every so often, a new term comes along that represents an emerging scientific trend. Biotechnology, genetic engineering, tissue engineering, gene therapy, combinatorial chemistry, high throughput screening, and stem cells are some examples of past terms. Recently, nanotechnology has become a popular term representing the main efforts of the current science and technology. Nanotechnology, which ...

Nanoimprint lithography (NIL) is a promising nanomanufacturing technology that offers an alternative to traditional photolithography for manufacturing next-generation semiconductor devices. This technology involves coating an ultraviolet (UV)-curable monomer layer on the substrate and then imprinting it with a template containing topography corresponding to the desired substrate features. While...

Recent experiments show that external inplanar electric field can be employed to guide the molecular self-assembly in diblock copolymer (BCP) thin films to form lamellar nanostructures with potential applications in nanotechnology. We study this self-assembly process through a detailed coarse-grained phase-separation modeling. During the process, the free energy of the BCP films is modeled as t...

Abstract Microreactor-Assisted Nanomaterial Deposition (MAND) process offers unique capabilities in achieving large size and shape control levels while providing a more rapid path for scaling via intensification nanomaterial production. This review highlights the application of continuous flow microreactors to synthesize, assemble, transform, deposit nanostructured materials Solar Photovoltaics...

Nanoscale science and engineering are providing unprecedented understanding and control over the basic building blocks of matter, leading to increased coherence in knowledge, technology, and education. The main reason for developing nanotechnology is to advance broad societal goals such as improved comprehension of nature, increased productivity, better healthcare, and extending the limits of s...

Nanofountain probes (NFPs) are atomic force microscopy (AFM) probes designed for direct-write delivery of liquid molecular “inks” with sub-100 nm resolution. Liquid inks’ stored in an on-chip reservoir are fed through integrated microchannels to apertured dispensing tips by capillary action. This allows continuous delivery either to a substrate for direct-write nanopatterning, or to a cell for ...

This paper describes a case study representing the design essence of a prototype ultra-high vacuum artifact transport system (ATS) in an existing design repository (DR). Specifically designed for the purpose of transporting nanometer-scale dimensional artifacts at pressures ~10 -8 Pa, the ATS consists of a transport cart and an ultra-high vacuum (UHV) system. The artifacts are the result of nan...

DOI: 10.1002/admi.201500762 temperature, and solution processability makes it possible for the realization of a high throughput, roll-to-roll production process of high effi ciency photovoltaics, thus ending the gap between academic prototypes and industrial standards. While the prospect of harnessing these advantageous properties makes perovskites ideal candidates for next generation solar cel...
