Biography:

I was born in paradise and I was raised by Gods. This lasted during the first 10 years then the lights went out. I’m talking about the country of Albania and my family, friends and everyone involved in the formation of my personality. I was born into a fruitful land where everything was once organic, life was a beautiful dream, and love, it was just abundant. It helped form a concrete core that would later withstand, a revolution, a Great Depression, a civil war-like situation and lots of crime and violence. No matter what happened, I always made time for art. Despite the shortage of paper, writing and coloring tools, or any artistic infrastructure, I drew on the ground with a stick, I sculpted out of the asphalt dripping on the sides of old brick buildings, created toys, insects and figurines out of electrical cables and studied the smallest details I could see on all live plants and animals I got my hands on. My family and I arrived in America in April of 1998, due to my mom winning the green card lottery. It was here when art flourished again for me. While in high school, my best friend got me my first mural. Later on I attended college and earned a Masters in Architecture. Then eager to work on cooler projects, I ended up 3D modeling the hottest 3D printed high heel, ‘Biomimicry Shoe’, in collaboration with Marieka Ratsma. This made me internet famous, opened many doors and I eventually found myself in New York City, living the life of a rockstar, which only lasted about eight months. Lets not forget Shapeways, today’s largest global 3D Printing service provider, and second home for me to experiment, collaborate and grow. Eventually my wife found me on LinkedIn to collaborate on her shoe designs. We ended up falling in love and here we are today, making the craziest, most futuristic shoes on the planet.   

Abstract:

When we look at one’s career progression today, it goes something like this. Find passion, master the skills needed to pursuit passion, learn through trial and error, perfect one’s skills, become aware of big ideas, proliferate ideas through leadership and make a global impact. In simpler words, do what you love and outsource what you don’t. This approach has led humanity towards ever evolving progress, prosperity and technological marvels. However, it still leaves humanity with winners and losers and we finally have the right tools to improve our story. Instead of doing what we love and outsourcing what we do not, we automate the undesirable. This approach leads us to the tipping point, the transition from type zero to type one civilization (see Kardashev scale), we are moving from human doing to human being. I will tell you a story, enriched with animated visuals from my experience in leading a half a million dollar private footwear and apparel company towards automation, by simplifying the product creation process into clean steps, rewritten as algorithms to be fed to machine learning mechanisms on phase one. Next, the machines will breed between digitally human created 3d CAD models, similar to how nature breeds us and everything alive. Finally, bring in artificial intelligence to bridge the gap between creator and benefactor (client) allowing everyone involved to seamlessly influence the product throughout its entire life-cycle.

Abstract:

Experiments on the formation of nanoporous silicon and germanium layers with silver nanoparticles by low-energy high-dose ion implantation are observed. For this task Ag+-ion implantation into monocrystalline silicon and germanium substrates at energy 30, keV with doses from 7.5·1016 to 1.5·1017 ion/cm2 was realized. Surface nanoporous semiconductor structures were studied by scanning electron microscopy, imaging, and energy-dispersive X-ray analysis. It is demonstrated that nanoporous silicon and germanium with silver nanoparticles could be fabricated by Ag-ion implantation. The average sizes of porous holes and thickness of walls between porous in silicon are about 110-130 and 30-60 nm, respectively. Silver nanoparticles are synthesized and uniformly distributed over the silicon surface. In germanium, regular holes were not observed. A porous amorphous germanium layer of a spongy structure consisting of a network of intersecting nanofibers with an average diameter of ~10‒20 nm is formed. At the ends of the nanofibers, the formation of Ag nanoparticles is detected. It is found that the formation of pores during implantation with Ag+ ions is accompanied by the effective spraying of the silicon and germanium surface. Thus, ion implantation is suggested for the industry to be used for a formation of nanoporous semiconductor thin layers containing silver nanoparticles, which could be easily combined with the crystalline substrates for various applications such as, for example, solar cell. This study was supported by the Russian Science Foundation, project no. 17-12-01176.    .

Chen Lai

Shenzhen Institute Peking University, China

Keynote: Novel mesh based on nano bacterial cellulose and poly(lactide-co-glycolide) composite

Time : 332342

Biography:

Chen Lai received her PhD from Hunan University for studies on biomaterials. She is Vice director of biomedical engineering center in Shenzhen institute Peking University, with responsibility for research activities on bacterial nano-cellulose (BC). Major research areas are BC modification and its clinical applications

Abstract:

The current study was designed to evaluate and directly compare the biomechanics and biocompatibiltiy properties of the novel bacterial cellulose (BC) and poly(lactide-co-glycolide) (PLGA)/BC composite meshes. Composite mesh was characterized by Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM) and scanning electron microscopy (SEM), demonstrating that PLGA only adheres to the BC surface. Laser perforation generated isotropic, flat and stable structures that prevented deformation under pressure and reduced the risk of potential bacterial colonization. In contrast to the pure BC mesh, the results of the in vitro study, which involved protein adsorption and cell-material interaction, suggested that composite mesh preferentially adsorbed bovine serum albumin (BSA) and enhanced the expression of type I collagen in fibroblasts. PLGA/BC mesh caused less inflammation and was surrounded by newly formed connective tissue composed of type I collagen after implantation in a rabbit model for one week, demonstrating that the novel mesh is fully biocompatible and can integrate into surrounding tissues. From this study, PLGA/BC mesh may prove to be a viable clinical alternative to existing materials.

Daniela Wittmann

German Research Center for Artificial Intelligence, Germany

Keynote: Smart Clothing: Construction kit for multifunctional textileadapted electronic microsystems

Time : 10:00 A.M to 10:40 AM

Biography:

Daniela Wittmann has expertise in the field of textile and clothing technology with a focus on Smart Textiles. Her current work combines the industrial background of garment technology with the participative user-oriented knowledge from previous design-oriented projects at the Design Research Lab (University of the Arts Berlin) and the German Research Center for Artificial Intelligence (Interactive Textiles). In various interdisciplinary projects during the last years in the field of Smart Textiles, she was able to gain her in-depth expertise. She focuses on participative methods and design methods for the conception of use cases for wearables and processing of intelligent textile demonstrators.

Abstract:

Statement of the Problem: Since the development of conductive thread material the processing according to classic industrial textile and clothing manufacturing techniques has been possible. However, there are weak points such as the connection of the conductive thread with the electronic components. (1) Until now, very different techniques have been used to process textile circuits and to combine hard components with the flexible textile - often also from the classical craft. These prove to be neither economical nor reliable. However, this reliability plays a major role in the user acceptance of wearables. In addition, wearables often do not meet aesthetic requirements of the user. (2) With the acquisition of information about the user the acceptance can be increased. (3) Methodology and results: On the basis of an exemplary scenario in the potential medical field of application, the research area of interactive textiles at the DFKI uses participative methods to ensure usability and to determine the technical system requirements. To solve the problem, a modular system is being developed in the BMBF funding project. This makes it possible to process the textile circuit on an industrial scale without purchasing new machines or acquiring additional special know-how. The problem of break resistance of the electrical conducting paths is solved by the embroidery process, which at the same time offers reliable contacting of the components. In order to allow many variations in the design and thus a multitude of applications, an interposer is developed that can accommodate various electronic components by means of a click system. In cooperation with the project partners Bosch, TITV Greiz, WESKO, Smart-Battery-Solutions and KUZ Leipzig, reduction of production costs, reliability of the system and high user acceptance are achieved

Dr Abdennacer Benali

Institute Microelectronic Materials and Nanosciences of Provence

Keynote: Complex dewetting of ultrathin silicon films for large-scale nanoarchitectures

Time : 10:40 AM to 11:20 AM

Biography:

Dr Abdennacer Benali has his expertise in Molecular Beam Epitaxy for both III-V and IV-IV semiconductors. He worked on III-V nanowires for photovoltaics where he acquired a strong knowledge in the material elaboration field. He also worked on the dewetting of Si and SiGe layers on SOI substrates. He made strong collaboration with laboratories all over Europe during his different projects.

Abstract:

Silicon-based nanocrystals represent a promising resource both for next generation electronic devices and for nano-photonics applications but require precise size, shape and position control [1,2]. However owing to their large surface-area-to-volume ratio, thin semiconductor solid films are often unstable upon annealing. Under the action of surface diffusion the film breaks eventually forming isolated islands. This is one of the main factors impeding the use of ultra-thin silicon films on insulators (UT-SOI) for the further miniaturization of electronic components. Here, with an e-beam lithographic method, we demonstrate the ultimate control of UT-SOI dewetting for the precise formation of complex nano-architectures featuring extremely reduced fluctuations of size, shape and positioning (a few %) over hundreds of repetitions and on large scales [3,4]. The solid state dewetting initiated at the edges of the patterns controllably creates the ordering of nanocrystals (NCs) with ad hoc placement and periodicity [5,6]. The NC size is tuned by varying the nominal thickness of the film while their position results from the association of film retraction from the edges of the lay out and Rayleigh-like instability. Islands formation, organization, positioning and composition are studied by dark-field, atomic force microscopy and scanning electron microscopy (Figure 1). Predictive phase-field simulations of the mass transport mechanism, assess the dominant role of surface diffusion providing a tool for further engineering this hybrid top-down/bottom-up self-assembly method (Figure 2). We also investigate the influence of adding a Ge flux during the dewetting. Finally, we show the feasibility to perform ultra-long Si nanowires on SiO2 and also core-shell structures by adding SiGe fluxes with different compositions.
