Rutting Characteristics of Bio-Asphalt Binder Based on the Multiple Stress Creep Recovery Test Results [PDF]

open access: yesJournal of Rehabilitation in Civil Engineering
The phenomenon of asphalt binder aging can lead to various failures, such as rutting in the asphalt mixture. Rejuvenator materials are used to mitigate asphalt binder aging. Bio-asphalt, as a binder modified with bio-waste materials, offers environmental

Yogis, Ayurveda, and Kayakalpa: The Rejuvenation of Pandit Malaviya [PDF]

open access: yes, 2017
How should we read claims about health and well-being which defy common sense? Are claims of extreme longevity to be viewed as fraudulent, or as pushing the boundaries of possibility for the human body?

Aging Is a Key Driver for Adult Acute Myeloid Leukemia

open access: yesAging and Cancer, EarlyView.
Acute myeloid leukemia (AML) is a classical age‐related hematologic malignancy, and a key driver of AML is aging, which profoundly regulates intrinsic factors such as genomic instability, epigenetic reprogramming, and metabolic dysregulation, and alters bone marrow microenvironment.

Zwiększenie wskaźnika recyklingowego asfaltu : studium eksperymentalne [PDF]

open access: yes, 2014
Asphalt is material that can be recycled. In particular reclaimed asphalt (RA) contains aged binder, which limits the reuse of RA. In this study the rate of recycled asphalt was increased by adding a rejuvenator containing paraffin.

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

open access: yesAdvanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Optimization design of asphalt emulsion with rejuvenator towards a uniform distribution inside the damaged porous asphalt mixture for a better ravelling resistance

open access: yesCase Studies in Construction Materials
Porous asphalt (PA) pavements usually meet the ravelling disease after opening to traffic for several years. Spraying surface treatment (ST) emulsion to PA pavement is a feasible preventive maintenance technology to alleviate this problem.

Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.
