Experimental methods in chemical engineering: X‐ray fluorescence—XRF
Canadian Journal of Chemical EngineeringX‐ray fluorescence (XRF) is a non‐destructive spectrometric technique to detect elements with an atomic number from 11 (sodium) and beyond 92 (uranium).

Intercomparison of XRF Core Scanning Results From Seven Labs and Approaches to Practical Calibration
Geochemistry Geophysics Geosystems, 2020 X‐ray fluorescence (XRF) scanning of marine sediment has the potential to yield near‐continuous and high‐resolution records of elemental abundances, which are often interpreted as proxies for paleoceanographic processes over different time scales ...

Advanced Materials, EarlyView.A titania‐supported Co1/Ru single‐atom alloy catalyst enables efficient polypropylene hydrogenolysis. Ru─Co─Ru motifs maintain Ru activity while suppressing excessive chain scission to gaseous products. Both virgin and waste plastics achieve high, environmentally and economically optimal C11+ liquid yields, supporting sustainable chemical recycling ...

Advanced Materials, EarlyView.We reveal the electronic origin of hidden interfacial doping in monolayer MoS2 grown by MOCVD, identifying sulfate related and water like species as intrinsic donors. Through dry interface engineering approach, we demonstrate MOCVD‐grown single‐crystal MoS2 wafers as a transfer‐free platform for the reliable evaluation of intrinsic gate stacks and ...

Advanced Materials Technologies, EarlyView.ABSTRACT Real‐time insight into local chemistry is critical for reliable part quality in additive manufacturing, especially laser powder bed fusion (PBF‑LB/M), where rapid thermal cycles and localized evaporation can undermine part performance. Optical emission spectroscopy (OES) offers non‑intrusive, in situ plume monitoring, but detection geometry ...

Advanced Materials Technologies, EarlyView.Milled polycrystalline NMC811 cathode (MPC NMC) with smaller secondary particle and higher surface area had 1) greater cathode tortuosity, 2) reduced surface Ni on the cycled MPC cathodes consistent with surface reconstruction, and 3) increased Ni deposition from cathode‐anode crosstalk, manifesting in lower functional capacity and higher impedance ...

Nigerian Journal of Technological Development, 2019 Abundant aquatic animal by-products are available in Nigeria which include clam, oyster, rock Snail and periwinkle shells. These are usually dumped on open lands without any economic value after fleshy parts of these animals had been consumed by humans ...

Advanced Materials Technologies, EarlyView.The opto‐electronic response of polycrystalline (PEA)2PbBr4 thin films is investigated by correlating macroscopic photodetector performance with nanoscale mapping techniques. Grain boundary density is systematically tuned through crystallization control and linked to device responsivity.
