Look at USDA needs


applied work


Grand Challenges:


1)

Renewable sources to replace petroleum.


2)

Production of value
-
added materials through nanoscale processes/materials.


3)

Favorably impact of CO
2

and wa
ter management.


4)

Sustainable smart fields and feed stocks.


5)

Management of local and environmental emission


6)

Reduction and/or conversion of waste into value
-
added products.


7)

Provide a new avenue of business for the producers by producing new nanomaterials.


Examples of 3
-
5 year achievable products:


1)

Hurricane
-
resistant houses based on nanocomposite materials.


2)

Nanocatalysts for conversion of vegetable oils to biodegradable industrial solvents and bio
-
based fuels.


3)

Printable bio
-
coating for environmental fri
endly disposable materials.


4)

Self
-
healing materials from self
-
assembled
-
fatty acids for safer airplanes.


5)

Improve food quality through nano
-
scale processes to convert/modify the composition of
various food types.


6)

Agriculture
-
derivatized biopolymers for i
ndustrial and biomedical applications.


List of opportunities:


1. Use nanocatalysts to help convert biomass to biofuels team up with materials science people
to design nanocatalysts (corn stalk and soybean)


2. Produce coatings atomlayer by atomlayer


surface modification (plasma technique) surface
modification and coatings using nanoscale techniques


modify properties of agricultural
materials and packaging;

3.

Biopolymer modification; chemical and/or physical; enhance processing for industrial
product
s, harvesting, fractionation, understanding structure, functional processes,


4.

Mechanics of nanomaterials; improve understanding, knowledge, do we understand the
transition from bulk to nano in agricultural materials??? Change morphology, texture,
chemistry
, etc. to arrive at a better understanding; adapt materials; measurement methods;
apply new measurement techniques; to apply multiscale modeling to agricultural systems;


5.

Self
-
assembly; triglycerides


use them as templates for self
-
assembly; from all ag

oils;
biomimetics; how does silica get assembled in rice?
--

understand, mimic carbon tube
provides skeleton for self
-
assembly; nanoscale assembly; requires an extraordinary amount
of modeling;


6.

Redirect some agricultural crops to industrial crops rat
her than food crops to grow materials
necessary for high performance products.


7.

Control CO
2

levels


tailoring nanoscale phenomena to make value
-
added products and have
a beneficial effect on CO2 levels;


8.


Look at zeolite packs in lettuce pumps in oxygen

(fluidized bed catalysts); nanobased
materials to facilitate the storage and distribution ; preservation of food; improvement of
packaging for food materials, keep out contamination etc.


9.

Imitate what the petroleum based industry has done; replace petr
oleum based monomers
with ag based monomers and so on; ag industry has a lot to offer that the petroleum industry
does not have to offer;


13. Resource use: nanomaterials can render processes more efficient; control extent of
fertilization and soil de
gradation, and therefore increase the longevity of ag systems



14. Have a plant that produces custom tailored nanomaterials / catalysts;


15. Education: generate enthusiasm for ag. Education; some programs are very visible and
attract many students;

bring nano to the table


make ag visible; make it exciting;
biologically engineer nanomaterials; need to show continuity between fundamentals and
applied ag.; draw attention to nanophenomena existing in nature; dyestuffs
--

heterogeneous, occurs at

the nanoscale; tell a story that will capture the imagination of the
young people;


16.

Restructure IP issues; industry working w/ academia and government


intellectual property
issues;


17.

Emphasize value of production of nanomaterials; state plays a sig
nificant role in risk
reduction; value added


needs to be large value added.


18.

New nanomaterials for personal
-
care products.


List of needs:

1)

Fundamental research, including synthesis, chemical modification, characterization and
structure
-
function relation
, and multi
-
scale modeling.

2)

Application of fundamentals to scale
-
up for industrial and agricultural situations.

3)

Robust, simple, and automated instrumentation.

4)

Education and outreach for effectively networking and extension.

5)

Networking with government and i
ndustrial nano
-
tech centers and laboratories.

6)

Bring the producers into business adventure and opportunities.

7)

Examine agricultural materials at the nanoscale under realistic environmental conditions;
temperature; humidity; pH; CO2; measurements under real
istic environmental
parameters; we are dealing with biological / living systems


wet world; supply
sophisticated instrumentation

8)

Create consortia between agriculture, industries, high tech industries, application of nano
to ag does not mean ‘tiny, un
affordable’ things;


Budget:


2 points

1)

Use bulk commodity (ag materials) to produce material / products

2)

Produce nanomaterials to improve safety, products, make sensors etc.
