Liquid Jetting‐Based Miniature Robotic Navigation in Confined Fluidic Spaces

Advanced Intelligent Systems, EarlyView.
We introduce a new class of liquid‐jetting‐based miniature robots (JetBots) ranging in size from mm‐to‐cm, featuring a unified approach in design, fabrication, and actuation. They demonstrate fast locomotion (30.3 cm/s), rapid steering (648.8°/s), and diverse functions, such as puncturing soft materials and unlimited cargo sampling and delivery, paving

Transforming waste into valuable resources: Recycled nitrile-butadiene rubber scraps filled with electric arc furnace slag

Cleaner Engineering and Technology
This study investigates the valorization of two industrial waste streams - nitrile butadiene rubber (NBR) scraps and electric arc furnace (EAF) slag – in the development of recycled NBR compounds filled with EAF slag as filler. A new recycling method for

Natural rubber: leather composites

Polímeros, 2005
Leather is a fibrous protein consisting of collagen in a three dimensionally crosslinked network. Chrome tanning of leather improves the appearance of leather but at the same time emits both solid and liquid chrome leather wastes.

Eco‐Friendly Aqueous Polymeric Binders for High‐Performance Graphite Anodes: Structure–Property Insights for Lithium‐Ion Batteries

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Polyvinylidene fluoride (PVdF) is commonly used as a binder material in the preparation of anode or cathode electrode slurries for commercial Li‐ion batteries (LIBs). High‐cost PVdF binder generally requires the use of toxic and environmentally unfriendly N‐methyl‐2‐pyrrolidone (NMP) as a solvent for dissolution.

Evaluation of the Efficiency of a Biobased Reactive Plasticizer on the Morphology and Properties of Sustainable Flexible Films Based on Poly(Lactic Acid) (PLA) Produced by Blown Film Extrusion

Journal of Applied Polymer Science, EarlyView.
A comparative investigation of two epoxy additives derived from cardanol (NC513 and NC514s) for production of films based on poly (lactic acid) (PLA), acetyl tributyl citrate (ATBC), and poly (butylene adipate‐co‐terephthalate) (PBAT) clarified their distinct roles, with NC513 mainly acting as a plasticizer, reducing viscosity and enhancing ductility ...

Constructing high roughness structure of rubber powder by swelling mechano-chemical method to improve interfacial bonding strength with natural rubber matrix

Industrial Crops and Products
Preparing rubber powder (RP) from waste rubber and incorporating it into natural rubber (NR) to save NR sources constitutes an effective strategy for the valuable recycling of waste rubber. Nevertheless, the relatively large particle size of RPs produced

Characterizing Heterogeneity in Post‐Consumer Rigid PP Packaging Waste: Implications for Object and Property‐Based Flake Sorting

Journal of Applied Polymer Science, EarlyView.
Commercial PP packaging grades span wide ranges in melt flow rate and stiffness, defining distinct application‐specific property spaces. Post‐consumer rigid PP products populate these spaces heterogeneously, with processing method and degradation shifting properties beyond virgin grade benchmarks.
