  • Using THz spectroscopy to analyse atomic layer deposited (ALD) TiN

    Oxford Instruments and das-nano demonstrate non-destructive wafer based thickness and resistivity metrology for PEALD TiN. Commonly titanium nitride (TiN) thickness and resistivity wafer fab in-line metrology is based on ellipsometry and 4-point probe resistivity mapping. Alternative and relatively slower or more complex methods are X-ray photoelectron spectroscopy (XPS), X-ray ...

  • Protective coatings for Underground utility concrete structures

    As our cities and municipalities grow older, the utility and wastewater infrastructure and corrosion preventive program for underground asset protection are aging with them. Municipalities and Utility Companies are struggling to handle rehabilitation measures and effective corrosion prevention programs to deal with prolonging the life of their buried assets. More municipalities are in the process ...

  • Why Geocells Outperform Geogrids for Road Construction

    Geocells (cellular confinement) offer a more effective and practical 3D design solution to load support challenges than multilayered 2D geogrid efforts. Geocells transfer applied loads instantaneously, delivering practical soil stabilization in a product that is fast and easy to install. How do geogrids work? Geogrids rely on rutting, displacement and lateral movement of the road ...

  • What are the main indicators of water quality?

    “Water is the driving force of all nature;” so said Leonardo da Vinci. The survival of our planet depends on the availability of water and the condition that it is in. It is therefore vital to make sure that it is able to provide a hospitable environment for those that live in it, and is free from harmful levels of substances for those that drink it. Not ...

  • Proliferation resistance and the nuclear renaissance

    Currently, nuclear power provides 16% of the world's electricity, using 439 reactors in 30 states and in Taiwan, China. This paper explores how emphasising proliferation resistance can guide decisions allowing increasing use of nuclear power without challenging international security. It reviews the definition of proliferation resistance and describes how proliferation resistance for a given fuel ...

  • Resistivity system voltage output

    One limit of FlashRES resistivity meter is its voltage output. It can output maximum voltage of 350v, this is because the multi-core cable of the FlashRES cannot withstand voltage over 350v. the multi-core cable contains 32 small wires, voltage higher than 350v will damage these wires and make the cable short circuit. We thus limit the maximum voltage output for safety reasons. Reference ...

  • Fiction EHC fluid resistivity

    Since the mid 1960's turbine hydraulic fluid systems have been using Fire Resistant Fluid (FRF) to control their turbine inlet valves. It is a known “FACT” that low fluid resistivity adversely affects the internal components of servo valves within the hydraulic fluid system. Root cause analysis studies conducted by numerous agencies have determined ...

  • Multidrug resistance in fungi

    One of the major advances serving to define the beginning of the era of modern medicine was the development of penicillin in the early 1940s as the first widely used antibiotic effective against microorganisms (reviewed in reference 111). In what has become an all-too-common trend, antibiotic-resistant isolates emerged soon after the large-scale use of penicillin to treat bacterial infections ...

  • Cultural resistance to change

    Organisational Change Management is the management of realigning an organisation to meet the changing demands of its business environment, including improving service delivery and capitalising on business opportunities, underpinned by business process improvement and technologies. It includes the management of changes to the organisational culture, business processes, physical environment, job ...

  • Flame Resistant Clothing

    Flame resistant (FR) clothing is designed as a means or protection against potentially fatal flash fire and arc flash environments.  The main source of fatal and serious burn injuries are usually due to the igniting of an individual’s clothing.  Flame resistant clothing allows precious time for the person wearing the clothes and also helps to prevent clothing ignition.  Keep in ...

  • HDPE - A Hydrocarbon Resistant Membrane?

    Most brownfield redevelopment and environmental protection applications require the use of a hydrocarbon resistant membrane.  However, each membrane material will vary in its ability to resist chemical attack and its effectiveness as a barrier to permeation.  It is essential that a barrier material prevents the migration of contaminants, thereby not harming the surrounding environment ...

  • A history of chemically resistant membranes

    The use of polymeric membranes for filtration of non-aqueous solutions started around 1960 and has been developed significantly since then [1]. Today, non-aqueous membrane filtration applications in chemical and pharmaceutical processing account for more than 25% of the global total polymeric membrane market [2]. ...

  • Roll along resistivity survey

    A roll-along survey is a method for operator to survey a long line. After the initial survey, the operator will leave one cable on the ground and move the instrument and cables forward. So there is always one cable overlap between two surveys. Alternatively, the operator can divide the cable in half and only overlap 16 electrode spacing. In this way, the opearator could complete the survey ...

  • The fundamental conductivity and resistivity of water

    Pure water has a very low. but not quite zero, electrical conductivity. This conductivity provides a probe into fundamental properties of water, including the electrochemical mobility of the hydrogen and hydroxide ions. Deviation from this value is a measure of trace ionic impurities. Ultrapure water (UPW). with impurities at or below the sub-parts-per-billion range, is used extensively in many ...

  • Triclosan resistant bacteria in sewage effluent and cross-resistance to antibiotics

    The purpose of this study was to identify triclosan tolerant heterotrophic plate count (HPC) bacteria from sewage effluent and to determine cross-resistance to antibiotics. R2 agar supplemented with triclosan was utilised to isolate triclosan resistant bacteria and 16S rRNA gene sequencing was conducted to identify the isolates. Minimum inhibitory concentrations (MICs) of organisms were ...

  • Determination of the cutting resistance model of soil

    Excavation methods depend on the rock conditions, location, etc. This paper investigated the penetration of an excavator blade into soil. Finite element modelling using the ABAQUS software and analytical methods were used to predict the horizontal forces due to blade movement with varying soil parameters such as friction angle, cohesion coefficient, and angle between soil and blade. The results ...
