Combined Effects of Thermal Cycling Aging and Reinforcement Content on the Ball‐On‐Disk Wear of Additively Manufactured Polylactic Acid Composites

Polymer Composites, EarlyView.
Thermal Aging and Tribological Tests of Additive Manufactured PLA Composites. ABSTRACT This study focuses on the additive manufacturing of pure polylactic acid (PLA) specimens and milled glass fiber (GF)‐filled PLA composites under thermal cycling aging and wear tests. Wear tracks have been analyzed via 3D optical profiling and SEM imaging.

Composite Fibers of Hydroxypropyl Cellulose and Alginate Spun From Aqueous Solution: Crosslinking Effects on Water Absorption and Mechanical Properties

Polymer Engineering &Science, EarlyView.
Alginate‐HPC composite fibers spun via CaCl2‐induced gelation process. Fiber diameter ranges from 100 to 200 μm after air drying. Higher alginate boosts water absorption in dried fibers. HPC selectively diffuses out when fibers are soaked in water. Crosslinking with hexamethylene diisocyanate improves mechanical strength.

Effect of Crystal Polymorphism on Elastic Modulus and Hardness of Poly(Butylene 2,6‐Naphthalate) (PBN)

Polymer Engineering &Science, EarlyView.
The research provides insight into the mechanical behavior of the high‐performance polyester Poly(Butylene 2,6‐Naphthalate) containing different crystal polymorphs, adjustable by the conditions of melt‐crystallization. ABSTRACT The modulus of elasticity and hardness of poly(butylene 2,6‐naphthalate) (PBN) were investigated at different length scales ...

Internal Structure, Kinematics, and Prehistory of Frozen Debris Lobe‐A (FDL‐A), Brooks Range, Alaska

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Frozen Debris Lobe‐A (FDL‐A)—one of hundreds of FDLs in the Brooks Range of northern Alaska—is a slow‐moving landslide in permafrost that has been the subject of research since 2008 due to its close proximity to the Dalton Highway. Here, we synthesize more than a decade's worth of climate and surface measurements of monitored FDLs, and the ...

Controlled incubation, leachate, and pot assays of shrimp shell‐based compost for suppressing Verticillium dahliae in olive

Pest Management Science, EarlyView.
Shrimp shell compost suppresses Verticillium dahliae microsclerotia, enhances chitinase activity, lowers olive wilt severity and improves plant recovery under controlled conditions. Abstract BACKGROUND Verticillium wilt of olive (Olea europaea L.), caused by Verticillium dahliae Kleb., is difficult to manage because long‐lived microsclerotia persist in

Scalable low‐cost seabed landers: the missing link for sustained, integrated, long‐term observations in dynamic shallow seas

Remote Sensing in Ecology and Conservation, EarlyView.
Seabed landers, when equipped with a range of biotic and abiotic sensors, offer a non‐invasive and cost‐effective solution for ecosystem‐scale monitoring of Essential Biodiversity Variables (EBVs) and Essential Ocean Variables (EOVs) in dynamic shallow seas.

Understanding Interactions Between Sustainable Development Goals Within and Between Policy Programmes: The Case of Kenya's Dairy Sector

Sustainable Development, EarlyView.
ABSTRACT Achieving Agenda 2030 depends on addressing interactions between the sustainable development goals (SDGs). In this paper, we conceptualize SDG interactions as synergies or trade‐offs, incoming or outgoing, and internal or external, and analyze how SDG 2 (Zero Hunger) interacts with other SDGs within and across policy programmes that support ...

AI‐Driven Circular Construction Waste Management for Advancing Sustainable Development

Sustainable Development, EarlyView.
ABSTRACT Construction and demolition waste (C&DW) represents up to 40% of global solid waste, posing a significant barrier to achieving circular economy (CE) objectives and the Sustainable Development Goals (SDGs), particularly SDG 11 and SDG 12. However, construction waste management (CWM) systems remain constrained by fragmented data environments ...

Electrically Switchable Diffraction Grating Based on Electrophoretic Redistribution of Carbon Black Nanoparticles

Small, EarlyView.
Electrically reconfigurable diffraction gratings based on electrophoretic carbon black (CB) nanoparticles are demonstrated. Voltage‐driven particle redistribution forms periodic absorbing patterns with switchable wide‐ and narrow‐slit diffraction modes. The proposed diffractor exhibits negligible polarization dependence, wide‐temperature operation from

Thermal Instability Pathways of Aluminum‐Based Nanocomposites: The Role of Alloying‐Element‐Driven Precipitation and Amorphous Interlayers

Small, EarlyView.
Thermal instability mechanisms governing novel Al‐based PVD/ALD nanocomposites are uncovered through synchrotron XRD, STEM, APT, and micromechanical testing. Temperature‐dependent crystallite evolution reveals a defined stability window before degradation dominates, offering new insight into the design of thermally robust, functional Al‐based ...
