Handbook of bioplastics and biocomposites engineering applications (Wiley-Scrivener)
In today's world, bioplastics are becoming increasingly prominent owing mainly to scarcity of oil, increase in the cost of petroleum-based commodities, and growing environmental concerns with the dumping of non-biodegradable plastics in landfills. This book summarizes the field of bioplastics by illustrating how they form a unique class of research area that integrates pure and applied sciences such as chemistry, engineering and materials science, to initate solutions. Compelling science demystics this complex and often ambiguous branch of study for benefit of all those concerned with bioplastics.

Bayesian LSTM-Based Missing Data Estimation and Flexural Strength Assessment for Determination of Novel Smart Mobility Pavement Materials: Mgsub.2 Added Plastic Composites
The construction field needs to reduce carbon emissions; therefore, many methods are being attempted applying to materials research. Concrete and asphalt are the representative materials for the pavement system. However, a lack of aggregates and certain limits in binder replacement are the main obstacles to achieving a reduction in carbon emissions. This study aims to address the lack of sustainable alternatives in pavement materials by investigating recycled plastic composites with Mg(OH)[sub.2], thereby filling a research gap in low-carbon, mechanically viable solutions for smart mobility infrastructure. Three types of recycled plastics—polypropylene (PP), polyethylene terephthalate (PET), and OTHER (OTH) resins—were combined with Mg(OH)[sub.2] to produce nine specimen configurations. The mechanical behavior and flexural performance were evaluated through displacement–flexural stress curve tests, while missing experimental data were reconstructed using a Bayesian long short-term memory (BLSTM) machine learning approach. The BLSTM model achieved an average R[sup.2] of 0.8018 in testing and 0.7618 in validation, confirming reliable prediction capability even with a small dataset. All composites demonstrated a minimum flexural strength of 30 MPa, with PP-based specimens reaching approximately 40 MPa, confirming their suitability for pavement applications. These results highlight the flexural performance of each composite type, with PP emerging as the most promising candidate.

Review on Molecular Dynamics Simulations of Effects of Carbon Nanotubes (CNTs) on Electrical and Thermal Conductivities of CNT-Modified Polymeric Composites
Due to the unique properties of carbon nanotubes (CNTs), the electrical and thermal conductivity of CNT-modified polymeric composites (CNTMPCs) can be manipulated and depend on several factors. There are many factors that affect the thermal and electrical conductivity of CNTs and CNTMPCs, such as chirality, length, type of CNTs, fabrication, surface treatment, matrix and interfacial interaction between the matrix and reinforcement (CNTs). This paper reviews the research on molecular dynamics (MD) simulations of the effects of some factors affecting the thermal and electrical conductivity of CNTs and CNTMPCs. First, the chirality dependence of the thermal and electrical conductivity of single-walled carbon nanotubes (SWNTs) was analyzed. The effect of chirality on the conductivity of short-length CNTs is greater than that of long-length CNTs, and the larger the chiral angle, the greater the conductivity of the CNTs. Furthermore, the thermal and electrical conductivity of the zigzag CNTs is smaller than that of the armchair one. Therefore, as the tube aspect ratio becomes longer and conductivity increases, while the effect of chirality on the conductivity decreases. In addition, hydrogen bonding affects the electrical and thermal conductivity of the CNTMPCs. The modeling of SWNTs shows that the thermal and electrical conductivity increases significantly with increasing overlap length. MD simulations can be effectively used to design highly conductive CNTMPCs with appropriated thermal and electrical properties. Since there are too many factors affecting the thermal and electrical conductivity of CNTMPCs, this paper only reviews the effects of limited factors on the thermal and electrical conductivity of CNTs and CNTMPCs based on MD simulations, and further detailed studies are required.

Interface/interphase in polymer nanocomposites
Significant research has been done in polymeric nanocomposites and progress has been made in understanding nanofiller-polymer interface and interphase and their relation to nanocomposite properties. However, the information is scattered in many different publication media. This is the first book that consolidates the current knowledge on understanding, characterization and tailoring interfacial interactions between nanofillers and polymers by bringing together leading researchers and experts in this field to present their cutting edge research.
Eleven chapters authored by senior subject specialists cover topics including:
* Thermodynamic mechanisms governing nanofiller dispersion, engineering of interphase with nanofillers
* Role of interphase in governing the mechanical, electrical, thermal and other functional properties of nanocomposites, characterization and modelling of the interphase
* Effects of crystallization on the interface, chemical and physical techniques for surface modification of nanocellulose reinforcements
* Electro-micromechanical and nanoindentation techniques for interface evaluation, molecular dynamics (MD) simulations to quantify filler-matrix adhesion and nanocomposite mechanical properties.
