Fatigue
This chapter deals with the historical background of fatigue and mechanisms of crack initiation. It focuses on the growth of fatigue cracks, together with a consideration of design procedures and a discussion of some case studies. The fatigue lifetime is strongly affected by a number of factors, such as the type of lo…

Front Cover: Top and lateral views of the crystalline structures of the two nanoporous crystalline forms of syndiotactic polystyrene (sPS) are shown. The different packing of sPS helices in the two crystal lattices is responsible for the difference in shape and volume of empty space. The porosity is distributed as cav…

3D Reactor Physics Modelling Of Reduced-Moderation Water Reactor (RMWR) Fuel
The Reduced-Moderation Water Reactor (RMWR) is an innovative water-cooled reactor with some of the characteristics of a fast neutron reactor, which can achieve a high conversion ratio of more than 1.0 and a negative void reactivity coefficient. The conception of RMWR is built on established Boiling Water Reactor (BWR)…

The Efficiency of the burn-leach method in assessing the integrity of TRISO coated particle layers
The basic fuel unit of the High Temperature Reactor (HTR) of the Pebble Bed Modular Reactor (PBMR) is a uranium dioxide kernel coated with a buffer layer, an inner pyrolytic carbon (IPyC) layer, a silicon carbide (SiC) layer and an outer pyrolytic carbon (OPyC) layer and is commonly referred to as a TRISO particle. Th…
Materials at Extreme Conditions [Slides]
The area of warm, dense matter (WDM) has received considerable attention recently due its identification with an assortment of environments as diverse as the interiors of exoplanets, the atmospheres of stars, inertial confinement fusion capsules, and the plasma from laser interactions with materials from clusters to n…
Viewpoint: Molecules for Spin Devices
Researchers propose a new type of spintronics device, based on an organic molecule bound to a surface, which could act as a spin filter or a magnetic memory element.
Interaction of microorganisms with sheet silicates
To study the interaction between microorganisms and sheet silicates, nontronite (NAu-2), and chlinochlore (CCa-2) as a powder form less than 2 µm were incubated with two microorganisms; Streptomyces acidiscabies and Schizophyllum commune strains in liquid culture flasks for two months. CCa-2 is a non swelling mineral,…
A New Incorporation Method of Metallic Precursors Into a Nafion Film via a Drying Process for thePreparation of Metallic Nanocatalysts/Nafion
A new simple drying process was developed in order to prepare a metallic nanocatalysts/Nafion for self-humidifying membrane in a proton-exchange membrane fuel cell (PEMFC). Metallic precursors such as platinum(ll) bis(acetylacetonate) or palladium(ll) bis(acetylacetonate) was sublimed and simultaneously penetrated int…

Studies on the Characteristics and Durability of a Vertical Type Organic Transistor Using Indenofluorenedione Derivatives as an N-Type Active Material
We have fabricated a vertical type organic field effect transistor (OFET) using indenofluorenedione derivatives (IF-dione-F) as an n-type organic active material and dimethyldicyanoquinonediimine (DMDCNQI) as an n-type buffer layer. The configuration of the vertical type OFET was ITO (drain)/ IF-dione-F/Metal (gate)/I…
Synthesis And Foam Power Of New Biodegradable Surfactant
This work deals with the synthesis and the determination of some surface properties of a new anionic surfactant belonging to sulfonamide derivatives. The interest in this new surfactant is that its behavior in aqueous solution is interesting both from a fundamental and a practice point of view. Indeed, it is well know…
Comprehensive Centralised Surveillance System for Safe Operation of Radiological Laboratory
The ventilation system plays an important role in preventing the release and dispersal of radioactive materials. There are a set of radiation monitoring instruments installed in vantage points in the laboratory to monitor whether ambient radiation level is within safe limits. Novel implementation of collecting ventila…
