An archaeological mystery revealed by radiocarbon dating of cross-flow nanofiltrated amino acids derived from bone collagen, silk, and hair: case study of the bishops Baldwin I and Radbot II from Noyon-Tournai [PDF]

, 2014
Excavations in the cathedral of Tournai revealed two sepultures, which were identified by the excavators as those of bishops because of their special location in the cathedral. One burial was assigned to Baldwin I, who died in AD 1068, because (1) a ring

Evaluating the Impact of Cellulose Nanocrystals on the Performance of Polycarbonate Thin‐Film Nanocomposite Membranes for Treating Oily Wastewater

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT A new type of thin‐film nanocomposite (TFN) membrane was synthesized by incorporating cellulose nanocrystals (CNCs) into a polyvinyl alcohol (PVA) top layer on a polycarbonate (PC) substrate via dip‐coating. The synthesized TFC and TFN membranes (PC/PVA TFC and PC/PVA‐CNC TFN membranes) were evaluated using contact angle measurement, field ...

Characterization and Modeling of Industrial Phosphoric Acids' Rheological Behavior: Impact of Magnesium Monoxide on Viscosity

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigates the rheological behavior of industrial phosphoric acids (H3PO4) produced at the JORF–LASFAR phosphoric plant in Morocco, with P2O5 concentrations of 18%, 29%, 42%, and 54%. Rheological measurements were performed using a rotary cylinder rheometer over a shear rate range of 1–1000 s−1.
