Neural interfaces establish direct communication between the central nervous system (CNS) and a sovereign, man-made digital system. This technology is perhaps the most important advance in the study and treatment of the brain is the development of the neural interface. Nanotechnology fabrication methods can overcome the limitations of existing interface devices by producing electrodes with an extremely high surface to volume ratio, i.e., more probe units within the same volume, resulting in unprecedented specificity.

In addition to economic, social and political measures, new technologies can provide tools for poverty reduction. Many people in developing countries don't just lack money. Especially in remote regions, many also lack access to electricity, clean drinking water and basic sanitation, cooking facilities, healthcare, adequate housing, etc. The innovative solutions for developing countries supported by the use of nanotechnologies mainly target five areas: water; medicine; agriculture; food; and energy.

New work demonstrates that one of the most important security primitives, i.e. a true random number generator (TRNG), can be realized within the rigorous constraints required for future Internet-of-Things electronics. The solution-processability of semiconducting single-walled carbon nanotubes allows to meet these strict constraints by simultaneously enabling small-scale, low cost fabrication of low-power, ultra-thin, printable, and mechanically flexible security devices. This presents a significant milestone in enabling higher level cryptographic solutions using scalable solution processing.

The robustness, accuracy, and validity of an atomistic simulations hinge on the appropriate choice of force fields. Force fields are key for modeling the interaction between atoms of a matter under study, and the challenge is to have an accurate force field working for any specific material at any desired temperature. To serve this objective and make a benchmark as well as a shortcut for users to find their best force fields, scientists have examined a number of force fields for materials that are popular in micro- and nanotechnologies.

In recent years, researchers working on de-icing and anti-icing strategies have been inspired by biology and nanotechnology to develop nanocoatings and other nanostructured surfaces. Researchers now have demonstrated the ability to spatially control frost nucleation (ice formation from water vapor) and to manipulate ice crystal growth kinetics. This ice nucleation control and the confinement of ice crystal growth direction through manipulating roughness scale have not been reported before.

Carbon nanotubes (CNTs), by possessing a uniquely large disparity among its intertube and intratube interaction strengths, have been established as ultralow friction nanostructures and are serving as testbeds for tuning frictional response. In new woirk, researchers now have revealed the phononic origins of friction in CNT oscillators. This work, for the first time, provides a precise connection between individual phonon mode scattering and friction force.

Written by Nanowerk's Michael Berger, this just published book is a collection of essays about researchers involved in all facets of nanotechnologies. Nanoscience and nanotechnology research are truly multidisciplinary and international efforts, covering a wide range of scientific disciplines such as medicine, materials sciences, chemistry, biology and biotechnology, physics and electronics. Each of the book's chapters is based on a scientific paper that has been published in a peer-reviewed journal. Although each story revolves around one or two scientists who were interviewed for this book, many, if not most, of the scientific accomplishments covered here are the result of collaborative efforts by several scientists and research groups, often from different organizations and from different countries.
