MAESTRO explores the world in 2D

MAESTRO explores the world in 2D
To see what is driving the exotic behaviour in some atomically thin – or 2D – materials, and find out what happens when they are stacked like Lego bricks in different combinations with other ultrathin materials, scientists want to observe their properties at the smallest possible scales. Enter MAESTRO, a next-generation platform for X-ray experiments at the ALS at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), that is providing new microscale views of this weird 2D world.

Optical materials could lead to light bending devices

Optical materials could lead to light bending devices
Northwestern University researchers have developed a first-of-its-kind technique for creating entirely new classes of optical materials and devices that could lead to light bending and cloaking devices — news to make the ears of Star Trek’s Spock perk up. Using DNA as a key tool, the interdisciplinary team took gold nanoparticles of different sizes and shapes and arranged them in two and three dimensions to form optically active superlattices.

Self-organising organic molecules form complex materials

Self-organising organic molecules form complex materials
An international team of researchers lead by the Technical University of Munich (TUM) has discovered a reaction path that produces exotic layers with semiregular structures. These kinds of materials are interesting because they frequently possess extraordinary properties. In the process, simple organic molecules are converted to larger units which form the complex, semiregular patterns.

Antibiotics can benefit from latest type of cellulose

Antibiotics can benefit from latest type of cellulose
Produced by plants, algae and some bacteria, cellulose is an abundant molecule involved in the production of hundreds of products, from paper to fabrics to renewable building materials. It’s also one starting material for producing ethanol, a common fuel additive and renewable fuel source. Now, Stanford scientists have found a new type of cellulose in bacteria with properties that could make it an improvement over traditional cellulose for fuels and other materials, or for better understanding and treating bacterial infections.

Self-healing concrete uses type of fungi as healing agent

Self-healing concrete uses type of fungi as healing agent
America’s crumbling infrastructure has been a topic of ongoing discussion in political debates and campaign rallies. The problem of aging bridges and increasingly dangerous roads is one that has been well documented and there seems to be a consensus from both democrats and republicans that something must be done. However, spending on infrastructure improvement has continually gone down.

Designing metamaterials with quantum mechanics

Designing metamaterials with quantum mechanics
Engineers at Caltech and ETH Zürich in Switzerland have created a method to systematically design metamaterials using principles of quantum mechanics. Their work could pave the way for wider use of metamaterials in more mainstream applications by creating a purpose-driven framework for their design. Metamaterials are engineered materials that exploit the geometry of their internal structure to manipulate incoming waves.

Topological materials could boost the efficiency of thermoelectric devices

Topological materials could boost the efficiency of thermoelectric devices
What if you could run your air conditioner not on conventional electricity, but on the sun’s heat during a warm summer’s day? With advancements in thermoelectric technology, this sustainable solution might one day become a reality. Thermoelectric devices are made from materials that can convert a temperature difference into electricity, without requiring any moving parts — a quality that makes thermoelectrics a potentially appealing source of electricity.

Epoxy based dual curing adhesive

Epoxy based dual curing adhesive
Master Bond UV22DC80-10F is a single component, nanosilica filled compound featuring a UV and heat curing mechanism. This thixotropic, moderately low viscosity compound has a viscosity of 8,000-12,000 cps at 75°F (~ 23°C). It is said to provide outstanding dimensional stability and superior physical strength properties. Additionally, UV22DC80-10F is optically clear and offers the ability to be cured in shadowed out areas.

Latest methods in bionics via the use of natural structures

Latest methods in bionics via the use of natural structures
Biofilms are generally seen as a problem to be eradicated due to the hazards they pose for humans and materials. However, these communities of algae, fungi, or bacteria possess interesting properties both from a scientific and a technical standpoint. A team from the Technical University of Munich (TUM) describes processes from the field of biology that utilise biofilms as ‘construction workers’ to create structural templates for new materials that possess the properties of natural materials.

The world's smallest Mona Lisa

The world's smallest Mona Lisa
In 2006, Caltech's Paul Rothemund (BS '94)—now research professor of bioengineering, computing and mathematical sciences, and computation and neural systems—developed a method to fold a long strand of DNA into a prescribed shape. The technique, dubbed DNA origami, enabled scientists to create self-assembling DNA structures that could carry any specified pattern, such as a 100-nanometer-wide smiley face.
