Advanced Functional Materials, EarlyView.This study introduces a novel chloro boron subphthalocyanine/polymer blend OFET sensor achieving 0.005 ppb limit of detection for ammonia at room temperature and high selectivity against similar amines. An original theoretical framework is proposed to describe the sensing mechanism, relating analyte molecular volume and Lewis basicity to sensor ...

Advanced Functional Materials, EarlyView.Light reflectance increases along incidence angle and transmittance significantly drops around 90‐degree incidence angle. Here, we report two‐photon laser printed micro mirrors that redirect the skimming light beam into normal light absorption. Using this technique, light‐driven micro walkers and grippers are demonstrated by using grazing incidence ...

Bridges With Lightweight Aggregate Concrete Structures
The Baltic Journal of Road and Bridge Engineering, 2006 Traditionally the lightweight aggregate concrete (LWAC) has been applied in buildings for many years. The improvement of the technology of production, mix composition and execution has considerably changed the nowadays LWAC properties. The uses of various admixtures have increased the strength, stress-strain modulus and decreased the creep that allowed

Novel Functional Materials via 3D Printing by Vat Photopolymerization
Advanced Functional Materials, EarlyView.This Perspective systematically analyzes strategies for incorporating functionalities into 3D‐printed materials via Vat Photopolymerization (VP). It explores the spectrum of achievable functionalities in recently reported novel materials—such as conductive, energy‐storing, biodegradable, stimuli‐responsive, self‐healing, shape‐memory, biomaterials, and

Optimising dosage of Lytag used as coarse aggregate in lightweight aggregate concretes
Journal of the South African Institution of Civil Engineers, 2013 Lytag, manufactured first by pelletisation of a mixture of fly ash, bentonite and water, and then by sintering the spherical pellets at about 1 300°C, is used as coarse aggregate for producing lightweight plain and structural concrete mixtures.
