Advanced Intelligent Discovery, EarlyView.The hydration behavior of C3S in seawater‐relevant solutions is studied based on experiments, boundary nucleation and growth (BNG) modeling, and machine learning. The main ions included in seawater modify hydration mechanisms, with MgCl2 showing the strongest acceleration effect at the same concentration.

Advanced Intelligent Systems, EarlyView.A digital twin framework is presented for modular soft continuum arms built from fiber‐reinforced pneumatic actuators. Cosserat rod models describe individual actuators, while virtual assemblies are formed through serial and parallel networks, preserving actuator‐level architecture and arm deformation.

Thermal and Electrical Characterization of the Carbon Nanofibers Based Cement Composites
Medžiagotyra, 2017 The paper describes the influence of chemical modification of vapor grown carbon nanofibers (VGCnFs) on the thermal and electrical properties of the cement composites. The surface modification of nanofibers was performed by means of ozone and nitric acid

THE CONSISTENCY OF CEMENT PASTES AND THEIR RHEOLOGICAL PARAMETERS
Acta Scientiarum Polonorum. Formatio Circumiectus, 2016 W pracy przedstawiono wyniki badań parametrów rozpływu oraz parametrów reologicznych zaczynów cementowych, wykonanych na bazie cementu portlandzkiego CMII 32,5R. Parametry rozpływu określono z wykorzystaniem specjalnej płyty trasowanej, natomiast cechy reologiczne określono za pomocą wiskozymetru rotacyjnego Viscotester VT 550, firmy Haake, o ...

The Anatomical Record, EarlyView.Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are based on single bones. However, multi‐bone sampling can attenuate these discrepancies, helping to infer growth dynamics and physiology of these extinct ...

The Anatomical Record, EarlyView.Polarized microscopic images of the outer bone cortex (a and b) and deeper trabecular bone (c and d) of the deer calcaneus in thin cross‐sections. The brighter gray levels reflect more oblique‐to‐transverse collagen fibers in the compression/dorsal bone (a, c) and the darker gray levels reflect more longitudinal collagen in the tension/plantar bone (b,

The distribution of sulfate in hydrated Portland cement paste
, 2007 Much of the sulfate in Portland cement paste is contained in AFm and AFt phases; measurements of sulfate sorption by C-S-H disclose that it is also a host for sulfate. The distribution of sulfate in AFt and AFm is also affected by carbonate. Quantitative
