The Effect of Temperature on the Properties of Fresh Self-Compacting Concrete

open access: yesArchives of Civil Engineering, 2016
The rheological properties of self-compacting concrete are closely influenced by temperature and the time. Previous studies which aim was to research the effect of temperature on self-compacting concrete workability, showed that the behaviour of fresh ...

From Geometry to Function: Programmable Mechanical Response in 3D‐Printed Adipose‐Inspired Soft Metamaterials

open access: yesAdvanced Functional Materials, EarlyView.
Geometry‐driven design of soft cellular metamaterials is systematically investigated by combining experiments, finite element modeling, and statistical prediction. The study quantifies how unit cell geometry and material properties govern stiffness, instability, densification, and energy absorption.

Advancements in Hypersaline Wastewater Treatment: The Promise of Quasi‐Liquid Surfaces to Reduce Salt Scaling

open access: yesAdvanced Functional Materials, EarlyView.
Durable quasi‐liquid polymer brush surfaces provide an anti‐scaling strategy for hypersaline brine evaporation and zero‐liquid‐discharge desalination. The smooth, liquid‐like QLS interface suppresses substrate‐side salt nucleation, promotes compact crystallization and dewetting, reduces crystal–surface contact area, and enables low‐adhesion salt ...

Giant Electrostriction in Halide Perovskites Revisited With Double‐Modulation Interferometry

open access: yesAdvanced Functional Materials, EarlyView.
A giant electrostrictive effect in lead halide perovskites had been reported previously. This work uses sensitive interferometry to measure the electromechanical response of various halide perovskite samples. The results reveal no intrinsic electrostrictive compression. Instead, the materials expand primarily under an applied electric field as a result

Development of self-compacting eco-concrete

open access: yes, 2006
Ever since its introduction and increasingly widespread use since the early nineties, new mix design methods of Self-Compacting Concrete (SCC) can hardly be recognized. Despite intensive research and a substantial number of publications in this new technology the design concept still mainly follows the so-called "Japanese method" introduced by Okamura /

Halide Perovskite Integrated Photovoltaic Cathodes Incorporating Pt on ZIF‐8‐Derived Carbon for Solar Hydrogen Production

open access: yesAdvanced Functional Materials, EarlyView.
A low‐Pt catalyst supported on zeolitic imidazolate framework (ZIF‐8)‐derived porous carbon and graphite is integrated with a halide perovskite photovoltaic, yielding cathodes that achieve a high photocurrent density (∼20 mA cm−2) under simulated sunlight and exhibit remarkable stability in acidic media over several days, thereby demonstrating a ...
