Progress 10/01/19 to 09/30/20
Outputs Target Audience: Forest and agriculture industries Packaging Industries Wood industries Pulp and paper industries Packaging Industries Changes/Problems:The major finding during this period is that hemicellulose from hardwood species such as poplar can be combined with metals such as Nickel, and/or copper and used in the field of electrochemistry as a sensor for the detection of hydrogen peroxide and in the manufacture of super-capacitor as evidenced by the initial 6 peer-reviewed published papersin the field of energy and fuels. We will continue to focus on the development of new high values products from forest and agricultureresidues to generate more interest and funding to maintain and manage of natural ecosystem and satisfy our rural community. What opportunities for training and professional development has the project provided?Ae student who was working on the making of flexiblefilms from chitosan and hemicellulose graduated and got a job in a packaging division of the USA army to work on the use of some wood components for the manufacture of flexible bioavailable and degradable food packaging.Another student working on the physical properties of the hemicellulose-based flexible film made using hemicelluloses such as xylan or galactan graduated with a Ph.D. and got a job as a university professor in the field of flexible biodegradable starches based films How have the results been disseminated to communities of interest?Several papers were published in peer-review journals in the area of electrochemistry and flexible film-based packaging containing essential oils to enhance their antibacterial properties in the journal of packaging food products, fuel and energies, and molecular biology. What do you plan to do during the next reporting period to accomplish the goals?Inthe future, understanding the impact of the addition or incorporation of biodegradable bioavailable hemicellulose on the properties of flexible films used in food packagingin the next 3 years.
Impacts What was accomplished under these goals?
Hemicellulose isolated from wood poplar was used to reinforce Chitosan-based films and supercapacitors in the design of Metal-OrganicFrameworks(MOF) for high-performance super capacitance and enzymeless hydrogen peroxide detector/sensor. Silver, copper, and titanic oxide well known for their antibacterial properties in the construction industry are under investigation for their potential antibacterial on paper and paper board based packaging. If effective, such treatment will help prevent the growth of some bacteria on paper-based products located on retail shops and distribution shelves.

Progress 10/01/18 to 09/30/19
Outputs Target Audience:Packaging Industry, Forest land owner, Forest Products Industry, agriculture engineering Changes/Problems:
Nothing Reported
What opportunities for training and professional development has the project provided?A graduation student was trained on the laboratory making of flexible film from biopolymers and the testing protocoles to evaluate their properties How have the results been disseminated to communities of interest?The findings were published in a peer reviewed journal of food packaging and included in lectures on packaging using biobased polymers from wood and agriculture residues to improve sustainability What do you plan to do during the next reporting period to accomplish the goals?How to improve the barrier properties of the biobased films, mainly water resitance by using milk proteins and lipids and also the potential use of a.aluminum oxide as an antioxidant b. cerrium nitrate to contrl photodegradation.
Impacts What was accomplished under these goals?
A biodegradablecomposite film made of chitosan xyan and carvacrol has been developed for food packaging application. Only 0.5 %v/v concentration acidic acid (at least 50% less than previous studies) showed to be sufficient to dissolve chitosan. As high concentrations of acidic acid can be harmful to plants, animals, and aquatic life, therefore our finding is more eco-friendly compared to chitosan-based films. Mechanical properties,Thermal analysis, and Antibacterial activity analysis have been investigated in this study. The film possesses high flexibility/toughness which satisfy the packaging requirements. Rubberwood from India was successfully treated with micronized copper to enhance the biological durability and extend their service life.

Progress 10/01/17 to 09/30/18
Outputs Target Audience:Several meetings with Forest land owners and Forest products Industry were organized to discuss information on age, species, sylviculture practices, genetic and other ecosystem parameters that may influence the properties of the lignocellulosic residues specimens that will be used. Changes/Problems:Information related to sylvilculture practises on the lignocelulose during growth is difficult to obtain. The relation between the properties of biopolymers from lignocellulose is known to vary with in species, genetic factors , sylviculure practices and ecosystems. These parameters are very important in the maximizatioon of the utilizationof forest products biopolymers. What opportunities for training and professional development has the project provided?Underraduate student was trained to perform tensile testing and data analysis. How have the results been disseminated to communities of interest?
Nothing Reported
What do you plan to do during the next reporting period to accomplish the goals?Improve the extraction yield of xylan from lignocelulose by using various solvents
Impacts What was accomplished under these goals?
The extraction of xylan from (CTMP)Chemica Treated mechanical hardwood species (poplar) pulp was conducted. about 10% Xylan was fragmented , purified and used to make flexible films. The characrization is underway. Xylan will be used to nreinforce the barrier properties of the film such as oxygen permeability and tensile strength.
