Investigation on the mechanical behavior of the multiple‐layered lining structure of a water conveyance tunnel with high internal water pressure

Deep Underground Science and Engineering, EarlyView.
This study presents large‐scale similarity model testing (geometric ratio 3.6) of an innovative multiple‐layered lining system—comprising exterior precast segments, middle self‐compacting concrete, and an interior steel pipe—for high‐pressure (0.75 MPa) water conveyance tunnels.

Fluorescence Behavior of Water‐Soluble Porphyrins Immobilized on LTA Zeolite and Its Chlorogenic Acid Polyphenol Sensing in Coffee Wastewater

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
During coffee bean and cherry washing, contaminants are released into water, making this process a major source of water pollution. Chlorogenic acid can be efficiently detected using hybrid zeolite–porphyrin materials by measuring fluorescence quenching, achieving detection limits lower than current regulatory thresholds.

Properties of Liquid Crystalline Elastomer Foams

Macromolecular Rapid Communications, EarlyView.
Controlled foaming of liquid crystalline elastomers (LCE) with expandable microspheres creates particle‐centred mesogenic interphases that enhance viscoelastic dissipation at low bubble fractions. Under impact, optimal damping shifts to moderate porosity, balancing interphase loss, bubble compression, compliance, and integrity.

Modeling the Elastic Recovery of PET Bottles via a Free‐Blowing of Preforms Campaign

Polymer Engineering &Science, EarlyView.
From free‐blown preforms to mechanical properties. ABSTRACT This study aims to quantify the elastic properties induced by biaxial stretching at different temperatures in order to simulate the complete process including the final elastic recovery. The elastic modulus is identified from geometric measurements obtained during free‐blowing experiments. PET

Iron(III) ion reinforced P(NiPAAm‐co‐AA) beads as tunable smart organogels

Polymer International, EarlyView.
Macroporous beads of PNiPAAm‐co‐AA copolymers were further crosslinked by iron(III) ions. The resulting beads are mechanically robust and reversibly responsive to a change of solvent from ethanol to ethyl acetate with half‐lives in the range of minutes.
