Lignin Nanoparticles and Their Biodegradable Composites
No full textThe plant-based bioresources play a key role in fulfilling human needs and overall socio-economic development. The world of today uses a variety of bioresources, which emanate from sectors like forestry, agriculture, aquaculture, livestock, and bio-wastes. Lignin was once considered a waste by-product, but recently, it has developed into a large bio-industry that has infinite applications. This chapter provides a concise classification of lignin and lignin-based materials within the research field of bioresources and discusses its development as a raw material in nanoparticles and biodegradable composites. Various strategies for extraction, separation, and processing of lignin from plant material are explained. A detailed account of newly found applications of lignin, lignin nanoparticles, and their biodegradable composites is given for multidisciplinary areas, for instance, in pharmaceuticals, industry, and value-added products. The chapter closes with a precise discussion of the issues, challenges, and prospects of each lignin material in the context of the application, processing, and development.</p
Molecular Imprinted Nanocomposites for Green Chemistry
No full textNanocomposite materials which are considered ‘green’ refer to non-toxic, biodegradable and renewable nanocomposites. The reasons of preferring green nanocomposites much more could be explained by environmental friendly, fully degradability, renewability and sustainability in all respects. Furthermore, the production of green nanocomposites should not be based on toxic chemicals. When their functions are definitely completed, they can be easily destroyed without harming the environment. The challenge with green composites arises from the difficulty of producing green nano-polymers to be applied as matrices in the construction of basic composites. Molecularly imprinted polymers (MIPs) have been extensively synthesized from various functional monomers. In green chemistry principles, elimination of toxic reagents in the analytical process, the use of reagents from a renewable source are performed. To date, there are some publications pointing out the utilization of harmless chemicals for the design of MIPs. It has been a great opportunity that a novel research area has emerged considering the combination of environmentally friendly reagents and traditional organic monomers for MIP synthesis. In this chapter, the recent advances in the field of both green synthesis and green applications by focusing the molecular imprinting technology are summarized, and the developments in green strategies are highlighted
Ceramic biomaterials for tissue engineering
No full textBioceramics, natural and synthetic, are designed to induce a strong bonding to bone and appeared as an alternative to metallic implants. Bioceramic materials currently used for the repair and reconstruction of hard and soft tissues can be categorized according its composition, structure, and properties. These biomaterials are grouped bioinert ceramics as alumina and zirconia, bioactive glasses and glass ceramics and bioresorbable calcium phosphates-based materials. The bioceramics concepts, namely physico-chemical, mechanical and biological properties, and respective applications in diverse fields of tissue engineering are discussed in depth herein. An up-to-date of bioceramics clinical trials is also considered. Based on the stringent requirements for clinical application, prospects for the development of advanced functional bioceramics for tissue engineering are highlighted for the future.The authors thank to the project FROnTHERA (NORTE-01-0145-FEDER-000023), supported by Norte Portugal Regional Operational Programme (NORTE 2020), under the PORTUGAL 2020 Partnership Agreement, through the European Regional Development Fund (ERDF).

Temporal Delta Layer: Training Towards Brain Inspired Temporal Sparsity for Energy Efficient Deep Neural Networks
No full textIn the recent past, real-time video processing using state-of-the-art deep neural networks (DNN) has achieved human-like accuracy but at the cost of high energy consumption, making them infeasible for edge device deployment. The energy consumed by running DNNs on hardware accelerators is dominated by the number of memory read/writes and multiplyaccumulate (MAC) operations required. As a potential solution, this work explores the role of activation sparsity in efficient DNN inference. As the predominant operation in DNNs is matrix-vector multiplication of weights with activations, skipping operations and memoryfetches where (at least) one of them is zero can make inference more energy efficient. Although spatial sparsification of activations is researched extensively, introducing and exploiting temporal sparsity is much less explored in DNN literature. This work presents a new DNN layer (called temporal delta layer) whose primary objective is to induce temporal activation sparsity during training. The temporal delta layer promotes activation sparsity by performing delta operation facilitated by activation quantization and l1 norm based penalty to the cost function. During inference, the resulting model acts as a conventional quantizedDNN with high temporal activation sparsity. The new layer was incorporated as a part of the standard ResNet50 architecture to be trained and tested on the popular human action recognition dataset (UCF101). The method caused 2x improvement in activation sparsity, with 5% accuracy loss.Electrical Engineerin
Design and synthesis of Ag NPs/Cellulose nanofiber-starch nano-bio composites for packaging applications
No full textAddressing problems due to conventional plastics requires a comprehensive approach involving waste reduction, improved waste management practices, and the development of sustainable alternatives to conventional plastics. In this study, a system was designed that can decorate cellulose nanofiber with silver nanoparticles (AgNP) and then used as a reinforcing agent in thermoplastic starch matrix. The composites were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Field emission scanning electron microscopy (FESEM), Transmission electron microscopy (TEM) and transport properties. The morphology and chemical modification of cellulose nanomaterials with silver nanoparticles were confirmed by FESEM, TEM and FTIR and the results indicated proper adhesion of silver nanoparticles in cellulose nanofiber. The addition of AgNP decorated cellulose nanofiber on thermoplastic starch matrix could effectively reduce cracks and pores and improves the overall performance of nanocomposite films. The unique properties of starch nanoparticles make them a promising candidate for diverse applications, showcasing their potential as a sustainable and versatile nanomaterial
