The combination of plant-based particles and water forms an 'eco' super-glue
25-Feb-2020
In a study published in Advanced Materials, researchers at Aalto University, the University of Tokyo, Sichuan University, and the University of British Columbia have demonstrated that plant-derived cellulose nanocrystals (CNCs) can form an adhesive that fully integrates the concepts of ...
Like Pavlov's dog, this thermoplastic is learning a new trick: Walking
06-Dec-2019
Researchers in Finland are "training" pieces of plastic to walk under the command of light. The method developed, published December 4 in the journal Matter, is the first time a synthetic actuator "learns" to do new "tricks" based on its past experiences, without computer programming. These ...
Clean carbon nanotubes with superb properties
21-Nov-2019
Scientists at Aalto University, Finland, and Nagoya University, Japan, have found a new way to make ultra-clean carbon nanotube transistors with superior semiconducting properties. Single-wall carbon nanotubes (SWCNT) have found many uses in electronics and new touch screen devices. Carbon ...
Tailor-made carbon helps pinpoint hereditary diseases and correct medication dosage
New method expands knowledge of carbon-based materials
18-Nov-2019
Sensors manufactured with carbon-based materials can provide uniquely accurate and real-time information on hereditary diseases or the concentrations of drugs in the body. In addition to medicine, carbonaceous materials are used in batteries, solar cells and water purification. Other elements, ...
Dyes and viruses create new composite material for photooxidation reactions
14-Aug-2019
A research team from Aalto University has developed a novel strategy to create virus-based materials for catalysis. The project, which is framed within the Horizon 2020 Marie Sklodowska-Curie actions, aims to pave the way towards the application of optically active biohybrid materials - a ...
Engineered metasurfaces reflect waves in unusual directions
New metasurfaces can even split energy into more than one
20-Feb-2019
In our daily lives, we can find many examples of manipulation of reflected waves such as mirrors to see our reflections or reflective surfaces for sound that improve auditorium acoustics. When a wave impinges on a reflective surface with a certain angle of incidence and the energy is sent back, ...
Quantum structures in super-chilled helium may mirror early days of universe
A pathway to recreate possible conditions of the early universe here on earth
18-Jan-2019
For the first time, researchers have documented the long-predicted occurrence of 'walls bound by strings' in superfluid helium-3. The existence of such an object, originally foreseen by cosmology theorists, may help explaining how the universe cooled down after the Big Bang. With the newfound ...
A new Bose-Einstein condensate created
18-Apr-2018
Nearly a hundred years ago, Albert Einstein and Satyendra Nath Bose predicted that quantum mechanics can force a large number of particles to behave in concert as if they were only a single particle. The phenomenon is called Bose-Einstein condensation, and it took until 1995 to create the first ...
New microscope sets a record for visualizing surface wetting properties
29-Nov-2017
Wetting is an everyday phenomenon that represents how well liquid spreads on a surface. When water comes into contact with an extremely water-repellent, or 'superhydrophobic' surface, droplets bead up and roll off easily. Aalto University researchers have developed a measurement technique called ...
Extraordinarily strong nonlinear optical graphene-like material could renovate nonlinear photonics
The discovery could enable high resolution imagining at low-power
26-Oct-2017
Nonlinear optics is a key enabling technology of our modern society, such as in imaging and high-speed data communication. But the traditional devices suffer from relatively small nonlinear optical coefficients of conventional optical materials. An interdisciplinary team of scientists from Aalto ...
