NEW CARBON FIBER SAVES

MONEY AND ENERGY

LeMond Composites, Minneapolis,

secured a licensing agreement with the

DOE’s Oak Ridge National Laboratory

(ORNL), Tenn., to offer what is said to be

an industry-disrupting carbon fiber to

the transportation, renewable energy,

and infrastructure markets. The break-

through process, invented by LeMond

CEO Connie Jackson and a research

team at ORNL, will reduce carbon fiber

production costs by more than 50%

relative to the lowest cost industrial

grade carbon fiber now available. The

LeMond version features mechanical

properties comparable to carbon fiber

costing three times as much. This new

method also reduces energy consumed

during production by up to 60%. The

innovative process will allow high vol-

ume, cost sensitive industries around

the world to reap the benefits of car-

bon fiber composites at a fraction of

the cost while incorporating chemistry

geared toward recyclability, says Jack-

son.

for producing 2D quasicrystals, which

could facilitate a better understanding

of these peculiar patterns.

Researchers successfully linked

europium with organic compounds,

thereby constructing a 2D quasicrystal

that has the potential to be extended

into a 3D quasicrystal. They also thor-

oughly elucidated the new network

geometry in unparalleled resolution

using a scanning tunneling microscope

and found a mosaic of four different

basic elements comprising triangles

and rectangles distributed irregularly

on a substrate. Some of these basic

elements assembled themselves to

regular dodecagons that, however,

cannot be mapped onto each other

through parallel translation. The result

is a complex pattern, a small work of

art at the atomic level with dodeca-

gonal symmetry.

HYDROGEL MATERIAL

SPURS BONE BONDING

Researchers at HokkaidoUniversi-

ty, Japan, developed a new kind of hy-

drogel that bonds spontaneously and

strongly to defective or injured bones,

suggesting potential use for treating

joint damage. The group previously

developed a tough, high-strength

network gel called double-network

gel (DN gel), which exhibits excellent

performance such as low wear and

inductive function for cartilage regen-

eration. However, as the gel’s main

component is water, it is difficult for

it to bond with other surfaces—a

major stumbling block in its practical

application. Now, the team success-

fully added hydroxyapatite (HAp), the

major inorganic component of bone,

to the surface of DN gel by dipping it

in calcium solution and phosphate

solution. The HAp-coated DN gel (HAp/

DN gel) was then transplanted into a

defective rabbit bone. Four weeks lat-

er, the coated gel had securely bond-

ed to the bone, while the non-coated

gel had not bonded at all. Electron

microscope analysis reveals that the

newly formed bone component in the

damaged area had penetrated into the

gel surface and fused to it seamlessly.
