What happens when materials take tiny hits

When tiny particles strike a metal surface at high speed — for example, as coatings being sprayed or as micrometeorites pummeling a space station — the moment of impact happens so fast that the details of process haven’t been clearly understood, until now. A team of researchers at MIT has…   more

Healing Deeper Flaws in Metal

Surface scratches are one thing, but what if materials could heal deeper flaws too? Research into self-healing metals, a completely different material, is also yielding promising results at an early stage. The idea is to create metals that can better cope with the repeated pressures of daily use…   more

Transparent Graphene

The vast majority of computing devices today are made from silicon, the second most abundant element on Earth, after oxygen. Silicon can be found in various forms in rocks, clay, sand, and soil. And while it is not the best semiconducting material that exists on the planet, it is by far the most…   more

Getting to the heart of carbon nanotube clusters

Integrating nanoscale fibers such as carbon nanotubes (CNTs) into commercial applications, from coatings for aircraft wings to heat sinks for mobile computing, requires them to be produced in large scale and at low cost. Chemical vapor deposition (CVD) is a promising approach to manufacture CNTs…   more

New technique allows rapid screening for new types of solar cells

The worldwide quest by researchers to find better, more efficient materials for tomorrow’s solar panels is usually slow and painstaking. Researchers typically must produce lab samples — which are often composed of multiple layers of different materials bonded together — for extensive testing.…   more

Researchers develop flexible, stretchable photonic devices

Researchers at MIT and several other institutions have developed a method for making photonic devices — similar to electronic devices but based on light rather than electricity — that can bend and stretch without damage. The devices could find uses in cables to connect computing devices, or in…   more

New property found in unusual crystalline materials

Most metals and semiconductors, from the steel in a knife blade to the silicon in a solar panel, are made up of many tiny crystalline grains. The way these grains meet at their edges can have a major impact on the solid’s properties, including mechanical strength, electrical conductivity,…   more

Fast-moving magnetic particles could enable new form of data storage

New research from the Beach Group has shown that an exotic kind of magnetic behavior discovered just a few years ago holds great promise as a way of storing data — one that could overcome fundamental limits that might otherwise be signaling the end of “Moore’s Law,” which describes the ongoing…   more

Materials Day Symposium 2017

Hosted annually by our friends at MPC, Materials Day includes a topical symposium followed by a student poster session. This year the symposium will be broad in scope and will involve primarily speakers from MIT. The theme will be Frontiers in Materials Research. Presentations will be given by speakers who represent MIT’s new generation of leaders in material research.   more

Future Semiconductors Could be 'Photocopied' Using Graphene

Semiconductor chips of tomorrow could one day be manufactured by using a "photocopying" process on super-thin sheets of graphene, rather than using traditional silicon, according to research being conducted at MIT. The MIT research involves graphene, which are single-atom-thin sheets of…   more

Converging on cancer at the nanoscale

This summer, the Koch Institute for Integrative Cancer Research at MIT marks the first anniversary of the launch of the Marble Center for Cancer Nanomedicine. The Marble Center for Cancer Nanomedicine focuses on grand challenges in cancer detection, treatment, and monitoring that can…   more

MIT.nano has its first public showing

The brand new, state-of-the-art MIT.nano building had its first public showing recently. The new building promises to be an enormously influential toolbox for many MIT departments, especially DMSE. Faculty and other researchers are excited for its completion slated for 2018. Krystyn Van…   more

Researchers “iron out” graphene’s wrinkles

Jeehwan Kim has a PNAS paper in which he confirms that a technique he previously developed does indeed create single domain graphene, meaning graphene that uniformly conducts electrons.…   more

Conquering metal fatigue

"Metal fatigue can lead to abrupt and sometimes catastrophic failures in parts that undergo repeated loading, or stress. It’s a major cause of failure in structural components of everything from aircraft and spacecraft to bridges and powerplants. As a result, such structures are typically built…   more

New method snips complex fibers into uniform particles

  "An interdisciplinary team of researchers enabled by the National Science Foundation-funded Materials Research Science and Engineering Centers (MRSEC) program has developed a way to break fibers or sheets of material into many tiny, almost perfectly uniform segments or strips. The…   more

Self-Stacking Nanogrids

Members of DMSE have discovered a way to stack block-copolymer layers into neatly…   more

Chemical Sensing on a Chip

Anuradha Agarwal is working with Lionel Kimerling and Juejun Hu of MIT's DMSE in the pursuit of shrinking and advancing sensory technology.  …   more
