anomaterials have been widely implemented in a variety
of beneficial applications to humanity; however, most
of these nanomaterials are not natural and synthesized by
complicated industrial processes with dilemmas of being
expensive, toxic, inefficient in energy and their potential
environmental impact. Therefore, there is a growing need to
implement green sustainable natural materials as precursors
in nanoparticles synthesizing (nano-organics) by using green
methods. The synthesized nanoparticles by green sustainable
methods are environmentally benign and safe to use in many
applications. There is a world movement towards creation a
combination between nanotechnology and green chemistry
to create and implement green technologies in synthesizing
smart materials. In our green chemistry lab, nano-organics
have been synthesized fromcellulose and clay by simple green
methods and applied in a number of important applications,
including desertification treatment, pollutants degradation
and drugs delivery.
Green mat for desertification treatment:
In 2019, Iraqi
invention aimed to create a natural green mat to reclaim
sandy lands or fix sand dunes. The invention idea meets
with the criteria of sustainable environmental and economic
development to overcome the scarcity of water, food and
energy especially in the developing countries.
The outer main layer of green mat formed from hydrogel as
a coating thin film for the purpose of water absorption falling
on it. This film of hydrogel protects the plant seeds (barley)
against the drought and atmospheric effects, assist the plants
to immerse their roots inside the mat’s layers and support
the roots extension. The practical results were obtained for
the agricultural reclamation of barley plants and stabilization
of sand and were compared with local methods to treat
desertification in Iraq or international methods, such as the
Indian and Japanese companies that carried out projects in
the UAE and other countries.
