In the time period 2010 2015, the worldwide annual production
of plastics is very likely to surpass 300 million tons,1,2 requiring
multiple amounts of petroleum and leading to hundreds
of millions of tons ofCO2 in addition to health risks for the public
due to the release of other types of emissions.1,3 A large amount
of plastics (at least 40% of the total consumption) is used in
short-term applications, and the resulting waste can quickly
lead to additional environmental damage unless adequate
waste management systems are in place. For example, conventional
petrochemical plastics are harmful for terrestrial and
sea animals as well as birds that tend to eat plastic residues;4
these impacts could be reduced by plastics that are biodegradable
by microorganisms. In short, petrochemical plastics are
not sustainable and bio-based sustainable plastics should be
developed to avoid problems caused by the petrochemical
plastics.

Plastics derived from biological sources: present and future: a technical and environmental review.

In the last half-century, the development of biodegradable polymeric materials for biomedical applications has advanced significantly. Biodegradable polymeric materials are favored in the development of therapeutic devices, including temporary implants and three-dimensional scaffolds for tissue engineering. Further advancements have occurred in the utilization of biodegradable polymeric materials for pharmacological applications such as delivery vehicles for controlled/sustained drug release. These applications require particular physicochemical, biological, and degradation properties of the materials to deliver effective therapy. As a result, a wide range of natural or synthetic polymers able to undergo hydrolytic or enzymatic degradation is being studied for biomedical applications. This review outlines the current development of biodegradable natural and synthetic polymeric materials for various biomedical applications, including tissue engineering, temporary implants, wound healing, and drug delivery.

Polyhedral Oligomeric Silsesquioxanes (POSS)-based Hybrid Soft Gels: Molecular Design, Material Advantages and Emerging Applications

Organic pollutants including industrial dyes and chemicals and agricultural waste have become a major environmental issue in recent years. As an alternative to simple adsorption, photocatalytic decontamination is an efficient and energy-saving technology to eliminate these pollutants from water environment, utilizing the energy of external light, and unique function of photocatalysts. Having a large specific surface area, numerous active sites, and varied band structures, 2D nanosheets have exhibited promising applications as an efficient photocatalyst for degrading organic pollutants, particularly hybridization with other functional components. The novel hybridization of 2D nanomaterials with various functional species is summarized systematically with emphasis on their enhanced photocatalytic activities and outstanding performances in environmental remediation. First, the mechanism of photocatalytic degradation is given for discussing the advantages/shortcomings of regular 2D materials and identifying the importance of constructing hybrid 2D photocatalysts. An overview of several types of intensively investigated 2D nanomaterials (i.e., graphene, g-C3 N4 , MoS2 , WO3 , Bi2 O3 , and BiOX) is then given to indicate their hybridized methodologies, synergistic effect, and improved applications in decontamination of organic dyes and other pollutants. Finally, future research directions are rationally suggested based on the current challenges.
