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
Large and detached eddy simulation of separated flow over 3D hill geometries with surface roughness to mimic flows over complex terrains
No full textWith the push to making wind power a significant contributor to the energy portfolio in the U.S. and Europe, there is considerable effort to deploy the currently available peta-scale computational resources to assess and improve well known simulation techniques, such as the large eddy simulation (LES) and detached eddy simulation (DES) techniques, to model the complex flows in wind farms, taken as a whole, as opposed to individual wind turbines. Simulating turbulent flows in wind farms, consisting of arrays of wind turbines, begins with the modeling and simulation of the atmospheric boundary layer (ABL) over complex terrain that is characterized by regions of separated flow with a high degree of turbulence anisotropy. Over the years there has been considerable work on applying LES and Reynolds Averaged Navier--Stokes (RANS) simulations over terrain geometries, such as the Askervein Hill, to understand turbulence closure models for flow over complex terrain. Such studies, however, have had limited success due to difficulties associated with the closure models in the near wall region of the flow. At the same time, turbulence simulations over \emph{canonical} geometries, such as the periodic and axisymmetric hills, have been shown to compare well with data obtained from laboratory scale experiments, where the inflow turbulence and boundary conditions are better characterized and defined respectively. In an effort to extend these canonical flows to be more representative of flows over complex terrain, this paper aims to present results of large and detached eddy simulations of separated flow over three dimensional hill geometries with roughness parametrization, with the objective of developing better closure models for flow over complex terrain
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).

On defect CFT and path integral methods for entanglement in quantum field theories
No full textIn the first few chapters of the thesis, we will study defect CFT methods based on the replica trick for characterizing quantum information in quantum field theories. We calculate a coefficient that characterizes the strength of the two point function of the displacement operator in the replica twist defect placed in a holographic CFT, which controls the second order shape dependence of Renyi entropy. We introduce defect CFT methods for calculating correlation functions involving the modular Hamiltonian together with probe operators inserted at lightcone separation. We use these methods to further calculate correlation functions involving modular flows of these probe operators. Tomita-Takesaki theory constrains these correlation functions, which when combined with our defect CFT calculations, provides a proof of the Quantum Null Energy Condition.
In the last few chapters of this thesis, we will calculate entanglement measures for states that are defined by a Euclidean path integral together with a source for an operator inserted in the path integral. We provide a purely Lorentzian formula for the modular Hamiltonians for these states for flat entangling cuts which systematizes the task of writing time-ordered expressions for relative entropy of these states with respect to the vacuum to all orders in the source. We further apply this method to calculate a formula for shape deformed modular Hamiltonian for the vacuum state to all orders in the shape deformation. In the case of null shape deformation, we recover the formula for the vacuum modular Hamiltonian for null cuts. We then calculate the shape deformation of relative entropy and provide evidence for the presence of a shock in the stress tensor expectation value when one performs the Connes cocycle flow of the state.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2023-12-01The student, Srivatsan Balakrishnan, accepted the attached license on 2021-07-16 at 15:10.The student, Srivatsan Balakrishnan, submitted this Dissertation for approval on 2021-07-16 at 15:25.This Dissertation was approved for publication on 2021-07-19 at 10:22.DSpace SAF Submission Ingestion Package generated from Vireo submission #16990 on 2022-04-06 at 17:16:09Made available in DSpace on 2022-04-29T21:41:38Z (GMT).
