Without
any tweezers or human intervention, nano boxes and other higher-order
polyhedra have been self-assembled by engineers at Johns Hopkins
University and mathematicians at Brown University. The process depends
on flattening the panels of the structures and relying on the
interaction of thermal changes and surface tension.

Thermal
stress can cause debonding between thin layers in microelectronics.
Taking advantage of the force generated by magnetic repulsion,
researchers have developed a new technique for measuring the adhesion
strength between thin films of materials used in these devices, and they
hope to apply the method improve solar cells or microelectromechanical
devices.

Engineers at the University of California, Davis, have invented a superthin nanoglue that could be used in new-generation microchip fabrication. Conventional glues form a thick layer between two surfaces, while the new nanoglue, which conducts heat and can be printed, or applied, in patterns, forms a layer the thickness of only a few molecules.

3M Scotch-Weld Instant Adhesive was recently responsible for a Guinness World Records-setting feat, lifting a 8.1 metric ton forklift in the air for one hour. The successful demonstration set a new world record for the heaviest weight lifted with glue.

For years, biologists have been amazed by the power of gecko feet, which let these lizards produce an adhesive force roughly equivalent to carrying nine pounds up a wall without slipping. Now, a team from University of Massachusetts Amherst has discovered exactly how the gecko does it, leading them to invent "Geckskin," a device that can hold 700 lbs on a smooth wall.

By manipulating the way bacteria "talk" to each
other, researchers at Texas A&M University have achieved an
unprecedented
degree of control over the formation and dispersal of biofilms—a finding
with
potentially significant health and industrial applications, particularly
to
bioreactor technology.

In the human world of manufacturing, many companies are now applying an on-demand, just-in-time strategy to conserve resources, reduce costs, and promote production of goods precisely when and where they are most needed. A recent study from Indiana University scientists reveals that bacteria have evolved a similar just-in-time strategy to constrain production of an extremely sticky cement to exactly the appropriate time and place, avoiding wasteful and problematic production of the material.

3M and IBM announced that the two companies plan to jointly
develop the first adhesives that can be used to package semiconductors
into
densely stacked silicon "towers." The companies are aiming to create a
new
class of materials, which will make it possible to build, for the first
time,
commercial microprocessors composed of layers of up to 100 separate
chips.

The editors of R&D Magazine have opened the nominations for the 2012 R&D 100 Awards competition, which will celebrate the 50th anniversary of the awards. If your organization introduced a new product this year, or is planning to, you can begin the entry process now.

Engineers at Oregon State Univ. have invented a new way to
use surface-mount adhesives in the production of low-temperature,
microchannel
heat exchangers—an advance that will make this promising technology much
less
expensive for many commercial applications.
