On‐Demand Activation of Thin Alginate Shell Encapsulated Volatile Liquid for Untethered Pneumatic Soft Actuation

Advanced Engineering Materials, EarlyView.
Phase‐changing liquids enable untethered pneumatic actuation in soft robotics but suffer from volatility and storage challenges. This work reports a simple method to encapsulate Novec 7000 within micron‐thin alginate shells via in situ injection and ionic crosslinking.

Study on the mechanical properties and pore structure of granulated blast furnace slag self-compacting concrete based on grey correlation theory

Journal of Asian Architecture and Building Engineering
Variations in the mechanical properties and pore structure of granulated blast furnace slag self-compacting concrete were studied. The grey correlation theory established the relationship between mechanical properties and pore structure. The test results

Upcycling of Disposable Face Masks into Water‐Resistant and Flame Retardant Foams

Advanced Functional Materials, EarlyView.
Disposable mask waste is upcycled into lightweight polypropylene‐based foams with tunable porosity and composite architectures reinforced by ear‐loop fibers. The sustainable solvent‐based process enables upcycling rates of 91% and solvent recovery of >90%.

Environmentally-friendly self-compacting concrete [PDF]

Journal of the Croatian Association of Civil Engineers, 2012
An experimental analysis of properties of self-compacting concrete, for both fresh and hardened states of concrete, is presented in the paper. Concrete mixes differed according to the type and quantity of mineral admixtures (metakaolin, fly ash). It was established that the addition of fly ash and metakaolin greatly improves mechanical properties and ...

Ultrathin, Stretchable, and 3D‐Printable Complementary Nanotubes–Polymer Composites for Multimodal Radiation Shielding in Extreme Environments

Advanced Materials, EarlyView.
A 3D‐printable dual‐mode radiation shielding material is introduced by combining boron nitride nanotubes and single‐walled carbon nanotubes in a stretchable PDMS matrix. The complementary nanotube network enables simultaneous attenuation of electromagnetic interference and neutron radiation while maintaining lightweight, mechanical resilience, and ...

Characterization of Self-Compacting Concrete

Procedia Engineering, 2017
Abstract This paper evaluates the rheological and mechanical properties of SCC with various dosages of viscosity modifying admixture (VMA). The rheology of fresh SCC is primarily described by its yield point and plastic viscosity. The yield point defines the force required to make the concrete flow.

Porosity of Self-compacting Concrete

Procedia Engineering, 2015
Abstract The construction industry demands more durable concrete with high performance. Self-compacting concrete (SCC) is developing gradually to meet many aspects of construction technology, especially reinforced concrete. On the other hand, durability properties still need some enhancements particularly in term of microstructure properties ...
