Continuous arterial spin labeling (CASL) magnetic resonance imaging (MRI) was combined with multivariate analysis for detection of an Alzheimer's disease (AD)-related cerebral blood flow (CBF) covariance pattern. Whole-brain resting CBF maps were obtained using spin echo, echo planar imaging (SE-EPI) CASL in patients with mild AD (n=12, age=70.7+/-8.7 years, 7 males, modified Mini-Mental State ...

Gas separation membranes are one of the lowest energy technologies available for the separation of carbon dioxide from flue gas. Key to handling the immense scale of this separation is maximised membrane permeability at sufficient selectivity for CO2 over N2. For the first time it is revealed that metals can be post-synthetically exchanged in MOFs to drastically enhance gas transport performanc...

In previous work, we have used Bayesian methods in the analysis of various models to explain past variation and forecast future values of the rates of growth of real GDP for 18 industrialized countries. Using these models, point and turning point forecasts were calculated and found to be reasonably accurate compared to those of benchmark and other models' forecasts. In this paper, Marshallian d...

Growing evidence indicates that the CO2 emissions from the combustion of fossil fuels are contributing to global climate change. One indispensable approach to controlling CO2 emissions to the atmosphere is carbon capture, utilization and sequestration (CCUS) from large point sources, such as coal power plants. Membrane technology has emerged as an important separation technology for CO2 capture...

Heavy metal pollution represents an urgent worldwide problem due to the increasing number of its sources; it derives both from industrial, e.g., mining, metallurgical, incineration, etc., and agricultural sources, pesticide fertilizer use. Features membrane technology are absence phase change or chemical additives, modularity easy scale-up, simplicity in concept operation, energy efficiency, sm...

Mixed-matrix membranes (MMMs) are promising candidates to improve the competitiveness of membrane technology against energy-intensive conventional technologies. In this work, MMM composed of poly(octylmethylsiloxane) (POMS) and activated carbon (AC) were investigated with respect to separation of higher hydrocarbons (C3+) from permanent gas streams. Membranes were prepared as thin film composit...

Flux and antifouling properties of mixed matrix membranes (MMMs) are yet to attain satisfactory status. The objective of this study is to find a method for mitigating the biofouling of poly(ether sulfone) (PES) ultrafiltration membranes via blending of thermoexfoliated vermiculite (VMT). Flow cytometry analysis shows that the behaviors of Bacillus subtilis 168 as a Gram-positive bacterium and E...

Achieving homogeneous dispersion of nanoporous fillers within membrane architectures remains a great challenge for mixed-matrix membrane (MMMs) technology. Imparting solution processability of nanoporous materials would help advance the development of MMMs for membrane-based gas separations. For the first time, we report a novel mechanochemical-assisted oxidative coupling polymerization strateg...

Moisture plays a key role in rock decay the built and natural environments. Rock-cut sites are particularly vulnerable to moisture-related weathering as they carved into outcrops do not have impermeable foundations or roofs retard flow of moisture. To characterise moisture dynamics its influence on rock-cut sites, we undertook monitoring campaign using non-destructive Microwave Measurement Syst...

Global energy demand is met in large part, by burning of fossil fuels, which causing global warming. Mixed matrix membranes (MMMs) with metal organic frameworks (MOFs) as fillers are an interesting alternative for capturing post combustion CO2 would make the sector sustainable. This research focused on synthesis MOF ZIF-94 from recycling its mother liquors and incorporation synthesized into a P...
