Fostering strategies in materials design

Finding a material to meet a minimum set of requirements can be a matter of trial and error, but knowing what will be the best material usually means understanding how it meets those requirements.

Atomic layer deposition – tooling up nanotechnology step by step

Atomic layer deposition (ALD) was already a useful tool for thin films in the 1980s, but it wasn’t until the end of the 1990s that the great match between the fabrication requirements in nanotechnology and the precision and control the technique can achieve became apparent.

Clinicians, companies and academics converge for Nano World Cancer Day 2016

From patient compliance and receptor-aided drug delivery, to regulatory taxonomy and funding, experts from different sectors came together to tackle the challenge of improving cancer treatments.

Light discussion on nanophotonics

During the 2015 International Year of Light, Nanotechnology brought together a panel of research experts to discuss the most pressing topics in nanophotonics research.

Single-electron devices come together

The ability to produce transistor structures so small that the current is just a single electron has created an intersection of research in quantum mechanics, thermodynamics, electronics, quantum information and metrology (with audio).

DNA sequencing: Nanotechnology unravels the code for life

The two main drivers in next-generation DNA sequencing technology are arguably increasing the speed and reducing the cost of DNA reading, both of which are likely to be tackled using nanotechnology.

Nano-cartography: knowing where to look

Mapping aids navigation. Now a well-stocked tool box of approaches provides information on how electronic, optical, mechanical and magnetic properties vary in nanosystems, with ever more refined techniques for accruing insights into the interplay of different system parameters.

Electron microscopy reaches new heights

(with audio) Researchers gathered at the inauguration of the SuperSTEM 3 electron microscope in Daresbury, UK, told nanotechweb.org about their outlook for the equipment and its high-resolution spectroscopic and spatial capabilities.

Nanophotonics and plasmonics: a great look for the International Year of Light

Studies of the interactions of light with nanostructures have revealed behaviour that can be exploited in new devices for slowing, filtering, trapping, confining and enhancing light.

MRS Fall 2014

We pick out some of the highlights from MRS Fall 2014.

Upconversion: When two wrongs make a right

Upconversion anti-Stokes processes allows emitted photons with higher energy than the energy of the incident photons, which may greatly benefit photovoltaic and photocatalysis technologies.

Making good of losses: generating heat with nanostructures

Nanoscale structures provide a rich playing field for generating useful heat from losses.

Bionanotechnology: Arrays in the future prospects of the field

Nanotechnology’s prominence in modern medicine is indisputable, but establishing exactly how biological systems will interact with nanostructures can be far from clean cut. We look at some of the progress in the field so far and trends that are emerging from the literature.

Carbon and terahertz nanotechnology: A promising alliance

The unique characteristics of both terahertz radiation and carbon nanostructures are encouraging a number of researchers to investigate potential physics and applications that combine them.

Brazil’s research investment yields returns at the nanoscale

We speak to researchers in the top nanomaterials labs in Brazil about their work and how it has been affected by recent research funding.

Lancaster University launches Quantum Technology Centre

Centre director Yuri Pashkin and Mark Rushforth from the faculty of science and technology at Lancaster University speak to nanotechweb.org about the new Quantum Technology Centre, which will be launched on Wednesday 28 May.

Thermoelectric nanodevices: Catering for global energy needs little by little

By enlisting the idiosyncrasies of nanostructures, thermoelectric power could be a useful source of energy particularly for small devices.

Ion age transport: Developing devices beyond electronics

Controlling the movement of ions and molecules through nanoscale channels offers a promising alternative to the use of traditional electronic current in a range of medical, sensing and energy devices.

Podcast: Trends in Nanotechnology conference comes to Japan

Anna Demming reports from nanoweek in Tokyo where the conference Trends in Nanotechnology joins the line-up of events in Japan for the first time.

Graphene research moves towards devices

Research into applications for graphene in real devices takes over from the initial studies on graphene production.
