Observations and Origin of Interfacial Heterogeneities in High-Performance Engineering Thermoplastics During Additive Manufacturing via Synchrotron X-ray Diffraction Open
Heterogeneity in extrusion-based 3D-printed thermoplastic polymers is generally both challenging to control and harmful to mechanical performance. Abrupt changes in material properties at the interfaces between roads are of particular inte…

Development of a Novel, All‐Aromatic High Tensile Modulus Liquid Crystalline Polyimide for Fused Filament Fabrication Applications Open
Polyimides (PIs), known for their thermal resistance, chemical stability, and mechanical properties, are often considered challenging materials to process, resulting in limited commercial availability of PIs for melt extrusion, injection m…

Mapping Crystallization Kinetics during 3D Printing of Poly(ether ether ketone) Open
Additively manufactured, high-performance polymers are increasingly used to realize complex, three-dimensional (3D) products but remain challenging from the point of view of performance control. To correlate and ultimately predict relation…

Abnormal Litter Induced by Typhoon Disturbances Had Higher Rates of Mass Loss and Carbon Release than Physiological Litter in Coastal Subtropical Urban Forest Ecosystems Open
The decomposition of abnormal litter caused by extreme weather events might play an increasingly important role in carbon and nutrient cycling in forest ecosystems under climate change scenarios, which needs to be fully investigated. In Au…

Controlling Rheology of Fluid Interfaces through Microblock Length of Sequence‐Controlled Amphiphilic Copolymers Open
Article 2200110 by Surita R. Bhatia and co-workers explores the rheology of fluid interfaces with sequence-specific amphiphilic copolymers. Copolymers contain short “microblocks” of 1–6 hydrophobic or hydrophilic repeat units. Results demo…

Controlling Rheology of Fluid Interfaces through Microblock Length of Sequence‐Controlled Amphiphilic Copolymers Open
Previous studies have demonstrated that films of sequence‐controlled amphiphilic copolymers display contact angles that depend on microblock size. This suggests that microblock length may provide a means of tuning surface and interfacial p…

Changes in plant debris and carbon stocks across a subalpine forest successional series Open
Background As a structurally and functionally important component in forest ecosystems, plant debris plays a crucial role in the global carbon cycle. Although it is well known that plant debris stocks vary greatly with tree species composi…
