Contribution of ultrafine particles to alkalinity in a limestone‐treated waterbody

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract While it is well recognized that suspended particles can bias titration‐based total alkalinity (TA), whether addition of minerals for alkalinity enhancement introduces systematic TA artifacts remains poorly quantified. To address this gap, we quantified the contribution of ultrafine particles (< 0.2 μm) to TA titration introduced by limestone (

Association Between Long‐Term Exposure to Air Pollution and Parkinson's Disease: Administrative Cohort of Older Adults in South Korea

open access: yesMovement Disorders, EarlyView.
Abstract Background Evidence regarding the association between long‐term exposure to ambient air pollution and Parkinson's disease (PD) remains inconsistent, particularly among older adults in Asian populations. Objective We aimed to examine the association between long‐term exposure to ambient air pollutants and incident PD in a nationwide ...

Computational Analysis of the Vibrational Response of Lunar Regolith Made of Nonspherical Grains

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Vibration‐based systems have shown that appropriately oriented and tuned mechanical oscillations can disrupt regolith interlocking and promote flow. Building on this evidence, the present study investigates vibration‐controlled granular discharge as a potential ISRU (In Situ Resource Utilization) strategy, with the aim of supporting ...

Lichen‐Derived Mineral Residue as a Renewable Particulate Filler in Polylactic Acid Biocomposites: Structure, Melt Rheology, Viscoelastic, and Flexural Behavior

open access: yesPolymer Composites, EarlyView.
Lichen residue, a renewable mineral‐organic material, was melt compounded with polylactic acid and triacetin in a twin‐screw extruder. ABSTRACT A lichen‐derived natural material, known as “höllük” in southeastern Turkey, is introduced as a renewable filler for polylactic acid (PLA).

Wear‐Activated Surface Engineering of Thermoplastic Polyurethane/Graphene Nanoplatelet Nanocomposites for Ice Friction Control

open access: yesPolymer Composites, EarlyView.
Wear‐activated surface engineering of TPU/GNP nanocomposites through improved filler dispersion and interfacial anchoring of functionalized graphene nanoplatelets, leading to finer post‐abrasion textures and enhanced ice traction. ABSTRACT Graphene‐reinforced thermoplastic polyurethane (TPU) composites offer a promising route for developing ...
