Abstract
Electrical phenomena are not limited to the inherent properties of a material but may also arise due to the orientation of the material building blocks. That is the case for the one atom-thin 2D carbon nanomaterial graphene, and possibly for other 2D material as well. By placing one sheet of graphene over another, rotating (“twisting) the other sheet to a special orientation, or ‘magic
angle’, and cooling the ensemble to a fraction of a degree above absolute zero turns graphene into a superconductor. Material properties seem to be orientation dependent on the nanoscale. The twist turns the material first into an insulator and then, into a superconductor. Remarkable is that combining two non-superconducting atomic layers together in a certain orientation turns it into a superconductor which shows he double life or Dr. Jekyl and Mr. Hyde character of graphene.
Those remarkable properties may arise from strong interactions or ‘correlations’ between electrons.
Here we would like to elucidate the ‘double life of graphene as it appears by simple twisting the individual monoatomic sheets of a graphene and exemplary other 2D materials double layer. This field i.e. manipulating electronic properties by a twist is often referred to as “twistronics”.
As the authors also work in a bigger more overarching project concerning 3D graphene and how the 2D graphene properties can be preserved also in the third dimension, the subject of “Twistronics” is relevant also to how, if and why “twisted” single sheet graphene layer may lead to altered properties in 3D graphene geometries. Those important aspects are elucidated.

Abstract
This Plenary Talk will feature a discussion on the Materials Science/Technologies Development of a unique new paradigm multifunctional material named ultrananocrystalline diamond (UNCDTM) in film (coating) form, and application to new generations of industrial, high-tech, external/implantable medical devices / prostheses, as described below:
UNCDTM films co-developed/patented by Auciello and colleagues are synthesized by microwave plasma chemical vapor deposition and hot filament chemical vapor deposition, using a patented Ar/CH4 gas flow into an air evacuated chamber, where C, CHx (x=1,2,3) species, produced in the plasma or on hot filaments, landing on the substrate surfaces, induce growth of low-cost polycrystalline diamond films with the smallest gran size demonstrated today (3-5 nm). UNCDTM films exhibit a unique combination of physical, mechanical, chemical, electrical, biological properties, namely: 1) hardest coating (98 GPa/similar to diamond gem-hardest material on Earth); 2) highest Young modulus (998 GPa/similar to diamond gem) coating; 3) lowest friction coefficient (0.02-0.04) compared with materials (≥ 0.5) currently used in mechanical pump seals/bearings, prostheses (e.g., dental implants, hips, knees); 4) first electrically conductive diamond coating, via N atoms inserted in grain boundaries, during N-UNCDTM film growth with Ar/CH4/N2; 5) UNCDTM coatings exhibit best biocompatibility because they are made of C atoms (element of life in the human DNA, cells, and molecules); 6) demonstrated as superior scaffolds for embryonic cell growth and differentiation to use cells grown in the lab for treatment of biological conditions.
Technological applications include: 1) UNCDTM-coated pump seals/bearings/AFM tips (marketed by Advanced Diamond Technologies (Auciello/co-founder/2003); 2) High-tech/medical devices, marketed by Original Biomedical Implants (OBI-USA-2013 and OBI-México-2016/Auciello-co-founder), described from less to highest current development, namely: a) UNCD-MEMS cantilevers biosensors and biting heart cells energy generation, powering new generation defibrillator/pacemaker, cell phones and mobile electronics; c) New generation of Li-ion batteries with ≥ 10x longer life/safer, using N-UNCDTM-coated metal electrodes; d) New generation of implantable prostheses (e.g., dental implants (in clinical trials in humans-50 patients received UNCDTM-coated DI in World Class clinic in Querétaro-México since 2018), hips, knees, stents and more) coated with UNCDTM, eliminating failure of current metal implants due to synergistic mechanical wear / blood interaction / chemical corrosion by body fluids; e) UNCD-coated silicon microchip implantable inside the eye as a key component of the artificial retina to return partial vision to people blinded by genetically-induced degeneration of photoreceptors (a device named Argus II is currently in the USA and EU markets by Second Sight, returning partial vision to people blinded by retinitis pigmentosa).

Abstract
In recent years, the need for collecting sunlight in an efficient and economical way has become one of the main goals of the photovoltaic-energy research field. Luminescent solar concentrators (LSC) based on doped polymer optical fibers (POFs) appears to be a competent solution since sunlight can be concentrated onto smaller areas of PV cells. Besides, POFs can easily integrate fluorescent dyes with spectral characteristics, especially suitable for solar concentrators. Additionally, a less cost and great availability of the used materials, no need for a sun-tracking system, great flexibility and ease of processing make them highly suitable candidates for the goal. Therefore, this presentation will provide an overview of the fabrication process and of optical properties characterization of our polymer optical fibers and preforms doped with different perylene-derivatives dyes with potential as fluorescent fiber solar concentrators.

Abstract
When dealing with the normal, everyday, statistical risk evaluation events, the methodologies currently at hand are quite successful for analyzing those jeopardies. When conditions fall into an extreme value type of event, Risk Mitigation become considerably more difficult to properly handle. When faced with a known extreme value event, a qualitative Generalized Extreme Value (GEV) approach is essential to help to avoid a high consequence loss. It is precisely during these extreme value events that most losses of high consequence statistically occur.

Abstract
There are only a few reports on luminescence dosimetry for undoped and doped MgO due to the lack of reproducibility for the luminescent signal in thermoluminescence (TL), regardless the synthesis method (i. e. solid state reactions, crystal growth, hydrothermal synthesis, co-precipitation synthesis, and sol-gel) [1]. Moreover, it is reported that introduction of alkaline metal ions into lanthanide-doped MgO enhances the photoluminescence (PL) signal significantly due to compensation charge effects with lanthanide ions [2], [3]. Motivated by the antecedents mentioned above, TL features of MgO co-doped with lanthanides and Li ions, obtained by solution combustion synthesis based on glycine and urea as fuels, are presented in this work. On the other hand, reliable dosimetric studies of any TL material should be based on a good knowledge of its kinetic parameters as well. Thus, kinetic parameters of the phosphors obtained have been calculated.

Abstract
The demand for advanced structural materials (Aluminum, magnesium, and titanium alloys) with tailored properties are increasingly being used in the automotive, aerospace and consumer industries for weight reduction, structural efficiency, and mechanical performance under elevated temperature and corrosive environment. These structural alloys are of industrial relevance and their properties are very sensitive to the variation in chemistry, which can be difficult to capture for multicomponent alloys. These properties also strongly depend on the solidification, thermal history, and formation of age-hardened precipitates, of which most are thermodynamically metastable. Experiments and handbook data cannot consider all possible variations in chemistry and processing conditions. Where this data is missing, computational thermodynamic couple with CALPHAD (Calculation of Phase Diagram) has emerged as a powerful tool for accelerating the development of high performing structural alloys, as well as process optimization and better predictions of material behavior throughout the material’s life cycle without costly, time-consuming experiments or estimations based on the limited data available.

Abstract
Scanning probe microscopy (SPM) is arguably the most versatile and powerful 3rd generation microscopy technology for studying samples at the nanoscale. It is versatile because an SPM can not only image in three-dimensional topography but also provides various types of surface measurements to the needs of scientists and engineers. Among the various developed SPMs, the Atomic Force Microscope (AFM) is the most widely used. The ability to measure forces, as indicated by the deflection of the AFM cantilever, has put it into prominence in surveying various properties of materials. Over the past three decades, AFM has evolved into an ideal methodology for non-destructive sample scanning with longer tip life, higher accuracy, repeatability, and automation. Along the way, various SPM techniques were developed to study the structures and functions of the target sample. In addition to the recent advances in SPM technology, it further expands the SPM application by combining it with other metrological technologies. Through this presentation, I will briefly introduce the 40 years of SPM technology development, contributions to real-life applications, and prospects.

Abstract
Three dimensional (3D) graphene has as high electrical conductivity, high surface area, and high electrical capacitance, which make them attractive as electrodes for electrochemical cells, capacitive deionizers and electrochemical supercapacitors. However, since graphene sheets act as ion-filters, they hinder diffusion of ions across them. This lacuna limits the thickness of 3D graphene electrodes, thereby reducing their cost effectiveness. By introducing nanometric-size holes in the graphene sheets, it is possible to make the electrodes both thick and with high efficiency for ion transport. Important factors determining the efficiency is size and areal density of holes, and arrangement of holes on sheets. The optimal size and arrangement of holes provide ionic flow paths which produce uniform distribution of ions within the electrode without hindering their transport. In this talk, we discuss various aspects associated with preparation and optimization of 3D holey graphene electrodes for variety of applications. This review is a part of our bigger project concerning how to preserve the properties of 2D graphene during its conversion to 3D graphene.

Abstract
Nanomedicine is the use of nanomaterials to improve disease prevention, detection, and treatment which has resulted in hundreds of US FDA approved medical products. While nanomedicine has been around for several decades, new technological advances are pushing its boundaries. For example, this presentation will present an over 25 year journey of commercializing nano orthopedic implants now in over 30,000 patients to date showing no signs of failure (over the past 5 years). Current orthopedic implants face a failure rate of 5 – 10% and sometimes as high as 60% for bone cancer patients. Further, Artificial Intelligence (AI) has revolutionized numerous industries to date. However, its use in nanomedicine has remained few and far between. One area that AI has significantly improved nanomedicine is through implantable sensors. This talk will present research in which implantable sensors, using AI, can learn from patient’s response to implants and predict future outcomes. Such implantable sensors not only incorporate AI, but also communicate to a handheld device, and can reverse AI predicted adverse events. Examples will be given in which AI implantable sensors have been used in orthopedics to inhibit implant infection and promote prolonged bone growth. In vitro and in vivo experiments will be provided that demonstrate how AI can be used towards our advantage in nanomedicine, especially implantable sensors. Lastly, this talk will summarize recent advances in nanomedicine to both help human health and save the environment.

Abstract
The global historic and eminently smart research aspects having to ‘Materials Science Nanotechnology’ attempts on hybrid composite utilization of liquid crystals and graphene to produce value-added chemicals from smart resources as well as improve novel device quality. Dielectric relaxations are studied at three different frequencies of a hydrogen bond liquid crystal chloro benzoic acid with nonyloxy benzoic acid. The process of synthesis is described and the synthesized mesogen is a monophase variant with nematic phase. Carbon-based nanomaterials (CNMs), like CNTs, graphene, carbon dots (Cdots), and some other CNMs, have recently drawn a lot of interest in their future application as an elevated-performance sensor implementation. For the first time in the history of liquid crystal dielectric work, we observed that in the present sample at higher frequency the process mentioned above is reversed. All the dielectric data points obtained at various temperatures when plotted they are found to converge at the ε∞ values and diverge at ε0 values. This process is referred as frequency cross over. Nematic growth order derived from dielectric studies is also presented. We explored that qualitatively different behaviors could emerge via the specific nature of the inter-component interaction. Mastering this mechanism could lead to various applications based on phase tunable properties and novel switching

Abstract
At the nanoscale, bone consists of a hierarchical structure of mineral crystals (hard material) and collagen (soft material). Inspired by bone’s nanoscale structure and properties, we design a nanocomposite with flexible pristine/polycrystalline graphene embedded in a hard Ni matrix. We model Ni graphene nanocomposites, with different structural arrangements for graphene in the Ni matrix. We use molecular dynamics to investigate the deformation of Ni-graphene nanocomposites under 3-point bending. We find that nanocomposites can deform approximately 30% more than pure Ni. The flexibility of the nanocomposite is optimally enhanced with a distance between graphene sheets greater than or equal to 3.05 nm. Polycrystalline graphene nanocomposites show approximately 15–20% improvement in bending modulus compared to pristine graphene nanocomposites. The increase in bending modulus of polycrystalline graphene nanocomposite is because polycrystalline graphene has higher interfacial shear strength compared to pristine graphene. We also find that the structural arrangement of graphene sheets is more important than increases in their volume fraction in the Ni matrix. These results suggest that graphene sheets scattered in the Ni-matrix is preferable to other structural arrangements. The results from this simulation could help in tuning nanocomposite with desired mechanical properties for various engineering applications.

Abstract
Metal-organic frameworks (MOFs) are porous crystalline materials constructed of organic linkers connected by metal clusters. Biomedical applications of MOFs have become of great interest in recent years due to their high porosity and tailorability to accommodate a wide range of guest molecules. The use of MOFs as drug delivery vehicles in cancer treatment has been widely explored as an alternative to traditional chemotherapeutic routes in efforts to increase efficacy and reduce harmful side effects. In addition to acting as carriers, the surface of MOFs can be decorated with moieties that discriminately bind to cancer cells allowing for advanced targeting capabilities. This presentation explores current work in the evaluation of novel small molecule inhibitor, PDZ1i combinatorial therapies using MOFs as drug delivery vehicles in the treatment of hepatocellular cancer. PDZ1i acts on MDA-9, a pro-metastatic and proangiogenic gene, associated with various types of cancer.

Abstract
Here, we discuss about various two-dimensional (2D) material synthesis process by the chemical vapor deposition (CVD) methods. Single crystal domain and large area monolayer graphene growth by catalytic approach were developed by using the solid precursor based thermal CVD techniques. Similarly, growth of high-quality hexagonal boron nitride (hBN) and monolayer tungsten disulfide (MoS2) layer has been achieved in thermal CVD approach. The synthesized materials can be used for fabrication of heterojunction photovoltaic, photocatalytic devices and energy storage/conversion devices. Further, synthesis of heteroatom doped graphitic carbon nanofibers by the CVD technique was developed for application in catalytic reactions. It was obtained that effective oxygen reduction reaction; oxygen evolution reaction and hydrogen generation reaction can be performed using the developed heteroatom doped graphitic carbon nanofibers as catalysts. Thus, I am going to introduce various novel material systems and their synthesis process for application in the energy-related devices.

Abstract
The textile industry is one of the polluting industries on the planet. Public awareness has increased manufacturer's responsibility and forced them to shift from linear to the circular production line to reduce the amount of environmental impact and cutting down the use of raw material. Recycling, remanufacturing and reusing are some practices that can be done to minimize the environmental impact and to keep used clothes out of the landfills.
One of these preventive actions is textiles recycling which involves so many uncertainties, such as quality, quantity, and type of the used materials.
In order to meet the needs of the increasing world population, recently, the concepts of sustainability and recycling have gained importance in the textile industry. The rapid change in today's trends has developed disposable habits. Thanks to recycling, it is possible to reuse the waste textile materials that we leave to nature. Due to the increase in agricultural production costs, it has become difficult to obtain the raw materials used for textiles. production with textile waste recycling can be advantageous. Using natural waste fibres instead of natural virgin Fibres to produce home textile products both reduces costs and makes production easier. In this study, recycled (waste) cotton was obtained by shredding white, 100% cotton and blended woven blankets and knitting, duvet covers and sheets purchased from a Governmental and private sectors of hospitals, military clothes , A 50%-50% waste-natural blend was created from the cotton obtained. Blankets fabrics were woven using open-end yarns numbered Ne24 and Ne12 produced from this blend. The physical characteristics of the fabric were investigated. The results obtained were analysed statistically and the effect of the blend created on the fabric quality was comprehensively examined.
And determining the types of magnetic parts while building machines to separate metal parts from old clothes and fabrics as a new approach machines architecture of emerging in magnetism for materials recycling of waste for producing textiles fibres
