Scientists at EPFL have developed robust and easy-to-implement multicolor super-resolution imaging. The approach is based on the simultaneous acquisition of two spectral channels followed by spectral cross-cumulant analysis and unmixing. They exploit fluorophore blinking and spectral crosstalk for the generation of additional color channels with super-resolved images.

Low-Cost Imaging System Poised to Provide Automatic Mosquito Tracking

TBMG-3718407/01/2020

Mosquito-transmitted diseases such as malaria, dengue, and yellow fever are responsible for hundreds of thousands of deaths every year, according to the World Health Organization (WHO). A new low-cost imaging system could make it easier to track mosquito species that carry disease, enabling a more timely and targeted response.

Semiconductors Can Behave Like Metals and Superconductors

TBMG-3719807/01/2020

Semiconductors are the active parts of transistors, integrated circuits, sensors, and LEDs. These materials, mostly based on silicon, are at the heart of today’s electronics industry. Metals, on the other hand, wire the active electronic components and are the framework for the devices.

Understanding Sensitivity in sCMOS Microscopy Cameras

TBMG-3719007/01/2020

The first sCMOS (scientific Complementary Metal Oxide Semiconductor) cameras were introduced some 10 years ago and are now the dominant sensor technology used in microscopy imaging cameras. In recent years, a new generation of sCMOS camera models based on back-illuminated sCMOS sensors has appeared. This new iteration of sCMOS camera technology promises even higher sensitivity than prior designs, and therefore may displace previous generations of front-illuminated sCMOS cameras and further push EMCCD (Electron Multiplying Charge Coupled Device) cameras to more niche applications.

Aerospace Fluid Power - Contamination Classification for Hydraulic Fluids

AS4059F (Historical)05/05/2020

This SAE Aerospace Standard (AS) defines contamination classes and levels for particulate contamination of hydraulic fluids and includes methods of reporting related data (Appendix A). The contamination levels selected are based on the widely accepted NAS 1638 cleanliness classes. The conversion from NAS 1638 cleanliness class specifications to AS4059 class specifications is defined. The comparison of the NAS 1638 classes to AS4059 classes and levels is provided and are defined and the differences explained (Appendix B). NAS 1638 classes based on weight of particles are not applicable to these classes and are not included. A contamination code has been added to describe the contamination levels of the fluid at the specified particle size ranges.

Artificial Intelligence Finds and Labels 2D Materials Instantly

TBMG-3683105/01/2020

Researchers demonstrated an artificial intelligence system that can find and label 2D materials in microscope images in the blink of an eye. Two-dimensional materials offer a new platform for the creation of electronic devices such as transistors and light-emitting diodes. The family of crystals that can be made just one atom thick includes metals, semiconductors, and insulators.

Development of a Method to Measure Soft Particles from Diesel Type Fuels

2020-01-0344

04/14/2020

Renewable fuels have an important role to create sustainable energy systems. In this paper the focus is on biodiesel, which is produced from vegetable oils or animal fats. Today biodiesel is mostly used as a drop-in fuel, mixed into conventional diesel fuels to reduce their environmental impact. Low quality drop-in fuel can lead to deposits throughout the fuel systems of heavy duty vehicles. In a previous study fuel filters from the field were collected and analyzed with the objective to determine the main components responsible for fuel filter plugging. The identified compounds were constituents of soft particles. In the current study, the focus was on metal carboxylates since these have been found to be one of the components of the soft particles and associated with other engine malfunctions as well. Hence the measurement of metal carboxylates in the fuel is important for future studies regarding the fuel’s effect on engines. The first aim of this study was to create synthetic soft

Comparison and Evaluation of Engine Wear, Performance, NOx Reduction and Nano Particle Emission of Diesel, Karanja and Jatropha Oil Methyl Ester Biodiesel in a Military720kW, heavy duty CIDI Engine Applying EGR with Turbo Charging.

2020-01-061804/14/2020

Rapid depletion of petroleum crude oil reserves,stringent pollution legislations and global warming, has given us the opportunity to work on bio fuels. Biodiesel can be produced from edible and non-edible vegetable oils,waste bio mass and animal fats.Biodiesel is renewable,bio gradable,sulphur free, non-toxic, oxygenated and green alternative fuel. Karanja and Jatropha oils are non- edible vegetable oils. Karanja and Jatrophaoil methyl ester biodiesel are prepared by transesterification process, using methanol. JOME and KOME have comparable performance with low gaseous emission characteristics, except higher NOx emission, in comparison to mineral diesel fuel. Recent emission legislations also restrict nano particle emission in addition to particulate matter, due to their adverse impact on health.In the present study, performance, combustion and emissions of CO, CO2, UHC, NOx and PM including nano particle emission characteristics, along with engine wear were compared for KOME, JOME and

Estimation of the Mechanism to Suppress Water Degradation of 1K Heat-Curing Epoxy Adhesive with High Durability

2020-01-022704/14/2020

In recent years, structural adhesives have been used to improve the rigidity, shock resistance, etc. of joints, and the requirements for these characteristics are expected to expand further. However, heat, loads, water, etc. can become deterioration factors for adhesives, and the consequent loss of strength is known to occur. In this study, the author has focused on water absorption deterioration, considered as one of the largest deterioration factors for adhesives, and has succeeded in providing high-water resistance to a one-component(1K) heat-curing epoxy adhesive through the addition of appropriate additives. This adhesive exhibited no hydrolysis during the 14-day 70 °C, 100% RH deterioration acceleration test, and strength retention and cohesive failure rates of 100% have been confirmed. In this study, the factors that provide high durability to the adhesive are identified, and the mechanism of how these factors suppress water absorption deterioration has been estimated.

Metal Belt CVT Seizure Monitoring System Using Wear Debris Analysis and Particle Measurement

2020-01-090704/14/2020

An apparatus that automatically samples lubricating oil and measures the size distribution of particles in the oil has been developed in order to monitor the state of engines and transmissions in operation. It is a widely known fact that when an engine or transmission seizes or experiences unusual wear, comparatively large pieces of wear debris are released. The goal of the use of the apparatus is to detect these particles of wear debris, stop testing before damage occurs, and clarify the causes. Seizure was, therefore, artificially induced in a transmission, and the wear debris in the oil was closely analyzed following the test. The results showed that when the simulated seizure occurred, large, elongated particles of wear debris were produced. Similar wear debris was observed in oil recovered from the market following the seizure of a component, and at present this is believed to be a type of wear debris characteristic of seizure. By knowing in advance the particle counter that
