High belite cement from alternative raw materials
Materiales de Construccion, 2014 Three high belite laboratory clinkers were prepared from traditional and alternative raw materials. Reference clinker was obtained from 77% limestone, 11% sandy clays, 11% fatty clays and 1% iron scales.

Carbonation of concretes containing LC³ cements with different supplementary materials
Semina: Ciências Exatas e Tecnológicas, 2022 Due to the clinkerization process during the Portland cement production, large amounts of CO2 are emitted, increasing the effects related to climate change (approximately 5-10% of global CO2 emissions come from cement production), consequently, the seek

Proposed textural indexes to quantify the distribution of the portland cement clinker phases
Materiales de Construccion, 1988 Some textural parameters to quantify the distribution of the Portland cement clínker phases are proposed. These parameters are evaluated under reflected-light microscopy and allow the characterization of Clinker homogeneity.

Biokatalysatoren für die Geranylierung von Peptiden mit Linearen und Zyklischen Prenylgruppen
Angewandte Chemie, EarlyView.A combination of genome mining, synthetic biology, and biocatalytic assays revealed enzymes that install linear and cyclized prenyl moieties on ribosomally or chemically synthesized peptides. The promiscuity of both enzymes, while being specific for modification of C‐terminal tryptophans, enables enzymatic access to peptide terpenoid hybrids ...

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection
Archaeological Prospection, EarlyView.ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...
