Synthesis of templated carbons starting from clay and clay-derived zeolites for hydrogen storage applications
(Wiley, 2015)
Clay and its recrystallized zeolitic derivatives were used in this study as templating agents for carbon nanostructured
materials. The conventional nanocasting process that involves impregnation with furfural alcohol and ...
Chemical–structural properties of South African bituminous coals: insights from wide angle XRD–carbon fraction analysis, ATR–FTIR, solid state 13C NMR, and HRTEM techniques
(Elsevier, 2015)
The chemical–structural properties of four South African bituminous coals were investigated using wide angle X-ray diffraction–carbon fraction analysis (WAXRD–CFA), attenuated total reflection Fourier transform infra-red ...
An analysis of the slow compression breakage of coal using microfocus X-ray computed tomography
(Taylor & Francis, 2015)
The degradation of coal and the production of coal fines during handling and
transport is a serious problem in processes that depend on closely sized large
particles. To minimize the production of fines, a fundamental ...
Model predictive control of an active magnetic bearing suspended flywheel energy
(SAIEE, 2015)
Flywheel Energy Storage (FES) is rapidly becoming an attractive enabling technology in
power systems requiring energy storage. This is mainly due to the rapid advances made in Active
Magnetic Bearing (AMB) technology. ...
Modeling hydrogen storage in boron-substituted graphene decorated with potassium metal atoms
(Wiley, 2015)
Boron-substituted graphene decorated with potassium metal atoms was considered as a novel material for hydrogen
storage. Density functional theory calculations were used to model key properties of the material, such as ...
Code-to-code comparison for analysing the steady-state heat transferand natural circulation in an air-cooled RCCS using GAMMA+ and Flownex
(Elsevier, 2015)
The GAMMA+ and Flownex codes are both based on a one-dimensional flow network modelling approach and both can account for any complex network of different heat transfer phenomena occurring simultaneously. However, there ...
Implementing a business improvement model based on integrated plant information
(Stellenbosch Univ, 2016)
The World Energy Council [1, 2] defines numerous challenges in the global energy arena that put pressure on owners and /operators to operate run existing plant better and more efficiently. As such there is an increasing ...
Does cancer risk increase with HbA1c, independent of diabetes?
(Cancer Research UK, 2014)
Background: The risks for several cancer types are increased in people with diabetes. Hyperglycaemia, hyperinsulinaemia,
inflammation and altered hormonal concentrations are common characteristics between the two diseases ...
Heading alignment with summarized inertial pose constraints
(IEEE, 2014)
A discontinuity seems to exist in present aided
inertial navigation systems – the operational availability of high
cost inertial navigation currently depends on the availability of
a valid GPS lock. In general GPS ...
