In this paper, Graphene Aerogel (GA) is prepared and investigated for its potential employment for solar energy harvesting applications. GA can be applied in solar cells applications as an absorption material and as a catalyst for fuel cells. GA is characterized by its extraordinary electrical conductivity and mechanical strength, in addition to a large surface and a low density. The electrical, mechanical, thermal, and absorption characteristics of GA can be tuned depending on the manufacturing process. Hence, GA is utilized in a multitude of applications such as: supercapacitors, air purification, oil and dye absorption from water, and water waste treatment. GA is also an excellent candidate for superior electrodes. In addition, GA are environmentally friendly materials since they are 100% recyclable and do not produce any ozone-depleting compounds. In this paper, GA is synthesized, characterized, and assessed for solar energy harvesting applications with the aid of absorption and Cyclic voltammetry (CV) tests. Results show that GA has immense potential in solar application due to its low band gap and outstanding optical and electrochemical properties. © 2022 IEEE.

Non-linear energy harvesting system was project to enhance interaction to ambient vibration that is wide band and low power which difficult the design for resonant solution. To improve efficiency of a non-linear design it was project a control system based in optimal linear control (OLC). Applying numerical evaluations it was possible to analyze the kinetic energy from the system as also the resulting output voltage. As main result there was a considerable increase of output voltage due controlled system in comparison to open loop for the same excitation. © (2013) Trans Tech Publications, Switzerland.

In this study, nerve conduits of chitosan and collagen composites with biocompatibility and biodegradability were fabricated. The effects of material composition and surface morphology on the axonal growth and directionality of rat epinephric pheochromocytoma PC12 were investigated. The cells were separated by a PDMS structure to simulate nerve injury, and the growth of axons of PC12 cells was observed under the separation of large gaps. At the same time, mitochondria extracted from osteosarcoma cybrid cells (C2-GFP) were added to the culture to investigate the effect of healthy mitochondria on axon differentiation and growth. The experimental results showed that the chitosan-collagen composite film can promote the growth of PC12 axons more effectively than the pure chitosan film. Cell culture results at different groove widths also showed that smaller grooves resulted in more axon numbers and longer axon lengths. Nerve injury simulation experiments showed that the nerve repair could be almost completed after 12 days of culture. Copyright © 2024 by ASME.

13th Biennial Norddesign Conference, NordDesign 2018

The objective of this paper is to propose functional guidelines for the assertive practice of the design thinking approach in organizational environments, and therefore to promote innovation. Considering the statement that contextual conditions directly influence innovation, a literature review is conducted in both design thinking and organizational structures bodies of knowledge in order to discover possible relationships between one another. A brief explanation about how designers make sense of things is presented in order to exploit connections between design thinking, creativity, and innovation, and after three specific organizational structures - formalization, hierarchy and functional differentiation - are analyzed, relationships between them and design thinking are established. Accordingly, three functional guidelines for organizations to exercise design thinking assertively are proposed: in terms of formalization, employees must be provided with clearly specified rules and procedures that encourage creative, exploratory, and risk friendly work and learning in a design conductive ecosystem so engagement, motivation and productivity can be increased;in terms of hierarchy, managerial responsibilities and roles must be designated so strategic decisions can be made quickly and co-creation can work;in terms of functional differentiation, integrative, human-centered, and collaborative work has to be contemplated with the existence of interdisciplinary teams for a rich mix of expertise and points of view so opportunities can be better seized. © Proceedings of NordDesign: Design in the Era of Digitalization, NordDesign 2018.

There is reasonable doubt that current arrangements for clinical training will sustain projected increased requirements for health education. It is evident that Simulation Education provides a solution to this sustainability problem, and the increasing sophistication of Virtual world technologies create opportunities to migrate elements from traditional to online models, thus addressing the issues of cost of access to traditional Simulation Centres. However, creating exciting online environments in isolation is insufficient in addressing the complex requirements of undergraduate health care training. The authors propose that by balancing the focus between cognitive reasoning structure and the need to establish an emotional connection, they have delivered a high quality, learner-centric online world that increases the "real world readiness" for undergraduates. Furthermore, by delivering the tool through a supportive online community of practice, the learner has a sustainable, continuous opportunity to practice essential skills in a safe environment before entering the clinical environment.

Human blood vessel organoids (hBVOs) have emerged as a system to model human vascular development and disease. Here, we use single-cell multi-omics together with genetic and signaling pathway perturbations to reconstruct hBVO development. Mesodermal progenitors bifurcate into endothelial and mural fates in vitro, and xenografted BVOs acquire definitive arteriovenous endothelial cell specification. We infer a gene regulatory network and use single-cell genetic perturbations to identify transcription factors (TFs) and receptors involved in cell fate specification, including a role for MECOM in endothelial and mural specification. We assess the potential of BVOs to generate organotypic states, identify TFs lacking expression in hBVOs, and find that induced LEF1 overexpression increases brain vasculature specificity. Finally, we map vascular disease-associated genes to hBVO cell states and analyze an hBVO model of diabetes. Altogether, we provide a comprehensive cell state atlas of hBVO development and illuminate the power and limitation of hBVOs for translational research. © 2025 The Authors

In this study, we demonstrated a novel micro periodic domain (MPD), results in rough surface on a silicon wafer, formed by self-assembled nano particles (SANP) and observed a 100 fold improvement in SERS signal for detection of Colon cancer miRNA21 on Au coated nano mushroom periodic domains compared to uniform nano mushroom domain on Si wafer. The single layer deposition on Silicon wafer is achieved by using the in house developed self-assembly deposition technique . The mono layer retains the shape of hexagonal arrangement in between nano particles and forms a periodic micro domains. © 17CBMS-0001.
