The principle is to use solar energy, collected on home roofs, which is then used to electrolyze water in order to produce hydrogen and oxygen. These gases are compressed and stored locally to match the gap between supply and demand. Hydrogen and oxygen are filled in adhoc car reservoirs, and subsequently transposed to electricity for fuel cell driven cars. Such a demonstrator system can already be built today; however the economic viability of the project depends on disruptive innovation based upon our capacity to face and resolve very demanding scientific and technical challenges in the years to follow. One of the main issues in this coherent effort is the optimization of the hydrogen production and usage chain. Several major steps, both in science and engineering, are needed to achieve the commercial exploitation of the overall concept.

Green energy - The sustainable energy source of the future 01262016Tony Green
Today we primarily use fossil fuels to heat and power our homes and fuel our cars. It’s convenient to use coal, oil, and natural gas for meeting our energy needs, but we have a limited supply of these fuels on the Earth. We’re using them much more rapidly than they are being created. Eventually, they will run out.
Here are three simple ways students can help the planet:
1) Start a simple recycling center at home to recycle glass, plastic, aluminum, and newspapers.
2) Create a compost pile using food scraps like egg shells, coffee grounds, and fruit peels to reduce waste.
3) Get creative by making cards from reused materials, carrying reusable items like water bottles and silverware, and choosing local organic food options.

There is nowadays a growing need for sensing devices offering rapid and portable analytical functionality in real-time as well as massively parallel capabilities with very high sensitivity at the molecular level. Such devices are essential to facilitate research and foster advances in fields such as drug discovery, proteomics, medical diagnostics, systems biology or environmental monitoring.
In this context, an ideal solution is an ion-sensitive field-effect transistor sensor platform based on silicon nanowires to be integrated in a CMOS architecture. Indeed, in addition to the expected high sensitivity and superior signal quality, such nanowire sensors could be mass manufactured at reasonable costs, and readily integrated into electronic diagnostic devices to facilitate bed-site diagnostics and personalized medicine. Moreover, their small size makes them ideal candidates for future implanted sensing devices. While promising biosensing experiments based on silicon nanowire field-effect transistors have been reported, real-life applications still require improved control, together with a detailed understanding of the basic sensing mechanisms. For instance, it is crucial to optimize the geometry of the wire, a still rather unexplored aspect up to now, as well as its surface functionalization or its selectivity to the targeted analytes.
This project seeks to develop a modular, scalable and integrateable sensor platform for the electronic detection of analytes in solution. The idea is to integrate silicon nanowire field-effect transistors as a sensor array and combine them with state-of-the-art microfabricated interface electronics as well as with microfluidic channels for liquid handling. Such sensors have the potential to be mass manufactured at reasonable costs, allowing their integration as the active sensor part in electronic point-of-care diagnostic devices to facilitate, for instance, bed-side diagnostics and personalized medicine. Another important field is systems biology, where many substances need to be quantitatively detected in parallel at very low concentrations: in these situations, the platform being developed fulfills the requirements ideally and will have a strong impact and provide new insights, e.g. into the metabolic processes of cells, organisms or organs.
This project targets the development of novel pocket X-ray sources and X-ray direct detectors that will be combined in a distributed network to solve important tasks, for example in the field of security, by ensuring reliable and real-time monitoring of failure sensitive parts in large manufacturing plants or in public transportation.
The miniaturized X-ray sources are based on multi-wall carbon nanotube (CNT) cold electron emitters and advanced microsystems technology. The electron field emission properties of CNTs, with their high current densities, make them prime candidates for cold emitter cathodes. Using CNT cold electron emitters will make it possible to miniaturize the whole X-ray source. Additionally, as opposed to classical thermionic emission, field electron emission of the CNT is voltage-controlled which allows for high modulation frequencies up to GHz level. The X-ray direct detectors in turn are based on crystalline germanium absorption layers grown directly on a CMOS sensor chip yielding high resolution and high sensitivity X-ray detectors. Single photon detection will allow for a significant improvement of contrast for applications in security, health care and nondestructive testing.
This project seeks to design innovative tools to measure in vivo biomechanical parameters of joint prostheses, orthopaedic implants, bones and ligaments. These tools, partly implanted, partly external, will record and analyze relevant information in order to improve medical treatments. An implant module includes sensors in order to measure the forces, temperature sensors to measure the interface frictions, magneto-resistance sensors to measure the 3D orientation of the knee joint as well as accelerometers to measure stem micro-motion and impacts. An external module, fixed on the patient.s body segments, includes electronic components to power and to communicate with the implant, as well as a set of sensors for measurements that can be realized externally.
This equipment is designed to help the surgeon with the alignment or positioning phase during surgery. After surgery, by providing excessive wear and micro-motion information about the prosthesis, it will allow to detect any early migration and potentially avoid later failure. During rehabilitation, it will provide useful outcomes to evaluate in vivo joint function. The tools provided can also be implanted during any joint surgery in order to give the physician the information needed to diagnose future disease such as ligament insufficiency, osteoarthritis or prevent further accident. The proposed nanosystems are set to improve the efficiency of healthcare, which is both a benefit to the patient and to society. Although the scientific and technical developments proposed in this project can be applied to all orthopaedic implants, the technological platform which is being built as a demonstrator is limited to the case of knee prosthesis. In addition, by reaching the minimum size achievable thanks to clever packaging techniques and also by reducing, or even removing, the cumbersome battery, it paves the way for a new generation of autonomous implantable medical devices.
There is an increasing demand for sensitive, selective, fast and portable detectors for trace components in gases and liquids, e.g. due to increasing concerns about atmospheric pollutants, and a need for improved medical screening capabilities for early detection of diseases and drug abuse. In that context, the project IrSens aims at building a versatile platform based on optical spectroscopy in the near and midinfrared range. Indeed, techniques based on optical absorption offer the possibility to realize a non-invasive and highly sensitive detection platform. It allows to probe the vibrational frequencies of the targeted molecules - most of which are located in the near and mid-infrared range, and to obtain an unambiguous signature of the investigated gas or liquid.
The idea is to create a photonic sensor platform with high performance and reliability which will leverage on the new source, detector and interaction cell technologies to create a new sensor element with vastly improved performance and lowered cost. These improvements will be demonstrated further by the incorporation into two pilot applications, the first one aiming at the demonstration of sensing in the gas phase, the second one in the liquid phase.
The document discusses a research project on 3D stacked chip architectures and interlayer cooling, including developing through-silicon vias for vertical electrical connections, using two-phase refrigerant cooling to remove heat from chip stacks more effectively than backside cooling, and experimental work on microchannel heat sinks, boiling visualization, and bubble dynamics simulation using an arbitrary Lagrangian-Eulerian technique.

Micro and nanotechnologies are the natural choice for enabling complex sensor nodes, as they are small (thus unobtrusive), cheap and low power. Carbon nanotubes (CNTs) are a perfect example of how nanosystems offer features unachievable with microsystems: their outstanding structural, mechanical and electronic properties have immediately resulted in numerous device demonstrators from transistors, to physical and chemical sensors, and actuators. A key idea of the project is to combine elements from the fundamental knowledge base on the physics of carbon nanotubes, gathered in the past several years, and the fundamental engineering sciences in the area of micro/nano-electromechanical systems, to develop novel devices and processes based on CNTs.
Specificaly, it seeks to demonstrate concepts and devices for ultra-low power, highly miniaturized functional blocks for sensing and electronics. Due to their small mass and high stiffness, doubly clamped CNTs can exhibit huge resonant frequencies. These are carbon nanotube resonators which, as recently demonstrated or predicted theoretically, can reach the multi-GHz range, can be tuned via straining over a wide range of frequency, offer an unprecedented sensitivity to strain or mass loading, exhibit high quality factors, and all these with a very low power consumption.
Recent observed environmental changes as well as projections in the fourth assessment report of the Intergovernmental Panel on Climate Change shed light on likely dramatic consequences of a changing mountain cryosphere following climate change. Some very destructive geological processes are triggered or intensified, influencing the stability of slopes and possibly inducing landslides. Unfortunately, the interaction between these complex processes is poorly understood. This project addresses the key issues in response to such changing conditons: monitoring and warning systems for the spatial and temporal detection of newly forming hazards, as well as extending the quantitative understanding of these changing natural systems and our predictive capabilities.
This project investigates the challenges in mixed signal platforms, such as those embedded in biomedical electronics, micro-systems, sensor networks and wireless communications, from both device and systems perspective. Demonstrators will be developed that cover generic sensor interface/data acquisition, passive telemetry, wireless body area network, wireless sensor networking and wireless wide area networks. The achievements will benefit other Nano-Tera projects focusing on the sensor/actuator side of microsystems, as well as wireless communications SoCs that will challenge the state-of-the-art in integration level, versatility and sophistication of nano CMOS systems.
This project is about further developing probe array techniques for life science applications, notably in the context of cancer research. The consortium shows the balance between experts in sensing technology as well as oncology.
This project aims to considerably improve cryptography on both the key distribution level and the encryption level. Quantum Key Distribution (QKD) is a secure way to generate and distribute keys, which is based on the fundamental laws of quantum mechanics. However, existing systems are too slow. The new QKD system will be capable of producing keys at 1 Mbps rate, which means it will allow 1 MHz OTP encryption for high-level applications.
The core of the system is an integrated chip, the NutriChip, which, as a demonstrator of an artificial and miniaturized gastrointestinal tract, will be able to probe the health potential of dairy food samples, using a minimal biomarker set identified through in vivo and in vitro studies. The project will develop innovative CMOS circuits at the nano-scale for high signal-to-noise ratio optical detection and propose a special microfluidic system closely integrating cell-based materials within the chip.
The NutriChip will be tested for screening and selection of dairy products with specific health-promoting properties, in particular immunomodulatory properties. The CMOS detection chip will be used to image down to single immune cells. For the biochemical validation of the NutriChip platform, the response of the immune cells upon the application of food will be examined by monitoring the Toll-like receptors 2 and 4, key molecules bridging metabolism and immuno-regulation in nutrition.
The document describes research on developing a fully implantable system for continuous monitoring of multiple human metabolic conditions. Key challenges include miniaturization to a cylinder less than 2mm in diameter and 20mm long, biocompatibility, reliable sensing of targets like glucose, pH and temperature, and low-power electronics for data processing and transmission. The proposed system uses a modular platform-based design with customizable probe-functionalized electrodes, nanostructured to enhance sensitivity, and electrochemical sensing principles to detect targets. Prototypes demonstrated remote monitoring of glucose, lactate and ATP levels with sensitivity in the pA/mM range and detection limits of hundreds of micromolar.
The document discusses fluidic mediated self-assembly for complex micro/nanosystems. It describes challenges in assembling different micro/nano devices and components. The key idea is using capillary forces at a liquid interface to align components through self-assembly. Various shapes and materials were investigated. Progress included fabricating MEMS parts, modifying surfaces for specific assembly, and experiments with in-liquid, field-induced, and template-driven assembly. The goal is to enable manufacturing of highly integrated micro/nano systems through self-assembly approaches.
This document describes the Intelligent Integrated Systems for Personalized Medicine (ISyPeM) project. The project aims to develop a platform for computer-assisted real-time dose adjustment of long-term drug therapies through personalized medicine approaches. In the short term, the project will focus on HIV therapies, immunosuppression for organ transplants, and anticancer therapies. The platform will integrate biosensors, algorithms, and low-power electronics to provide automated drug monitoring and delivery.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
