Pollution level detection in dump clay liners by hyperspectral imaging
Landfill is the most common and cost–effective method of waste disposal, with collection and transportation accounting for 75% of the total cost. A key point in waste disposal is the picking up and the drainage of percolation fluids to limit the risk of groundwater contamination. Aim of this study was to evaluate the possibility to develop fast and reliable methods to perform an in situ ...

Comparing the effects of nano silver size and coating variations on bioavailability, internalization, and elimination, using Lumbriculus variegatus
As the production and applications of nano silver (nano Ag) increase, it is essential to characterize fate and effects in environmental systems. Nano Ag materials may settle from suspension, therefore, our objective was to utilize environmentally relevant bioassays and study the impact, bioaccumulation, tissue distribution, uptake and depuration of nano Ag on a sediment‐dwelling invertebrate, ...

Quantitative Chemical Imaging: Bringing Laboratory Quality Control to the Production Line
Attributes such as safety, quality and speed are strong differentiators for domestic companies when competing globally. Everyone is talking about digitalisation, Industry 4.0, environmental protection, and 5G. Modern manufacturing facilities around the world are therefore striving to implement reliable quality control for their incoming and outgoing goods. To remain competitive with their ...

Postgrowth modification of monolayer graphene films by low-pressure diborane-argon plasma
Polycrystalline monolayer graphene films grown by chemical vapor deposition were exposed to a low-pressure inductively coupled plasma operated in a gaseous mixture of argon and diborane. Based on Langmuir probe and Optical Absorption Spectroscopy measurements, the discharge conditions were selected to be as “mild” as possible to minimize damage formation on graphene by very-low-energy ...

THE EVOLUTION OF “OPTICAL SORTING” IN WASTE RECYCLING
We know that the “Optical Sorting” concept is not new. But what do you really know about it? Did it emerge as an exclusive technology for the waste management and recycling sector? When did it start to be applied? BRIEF HISTORY OF OPTICAL SORTING Optical Sorting is not a 21st century thing. The idea as such emerged in the first decades of the 20th century. Following the desire (and need) to ...

What makes TERS `shine` today?
After more than 15 years since TERS had its first proof of concept, HORIBA Scientific and AIST-NT have created a solution that brings TERS as an analytical method to a completely new level. TERS is not only able to perform so-called point measurements, but now TERS spectra can be collected in every single pixel of a scan map. A TERS map is composed of more than tens of thousands Raman spectra, ...

Oct. 2018 Evolution: From Plastic Sorting to Process Analysis of Secondary Fuels
In Europe, the amount of plastics wastes produced amounts to about 25 million tonnes a year. On the average, no less than 37 kg plastic waste a year will be produced by each German, this amount being based on nothing else but packaging waste [1]. Quite often these plastics will end up as micro-plastics in the air, in the soil and in the sea and thus in our foodstuffs. To counteract this adverse ...
