Effects of azo dye on simultaneous biological removal of azo dye and nutrients in wastewater [PDF]

Royal Society Open Science, 2018
The potential disrupting effects of Azo dye on wastewater nutrients removal deserved more analysis. In this study, 15 days exposure experiments were conducted with alizarin yellow R (AYR) as a model dye to determine whether the dye caused adverse effects on biological removal of both the dye and nutrients in acclimated anaerobic–aerobic ...

Azobenzene's Cross‐Scale Optics and Photonics: Molecular Photoswitching, Mesoscopic Material Motions, and Adaptive Devices

Advanced Materials, EarlyView.
Azobenzene photoswitches translate molecular‐scale E/Z photoisomerization into macroscopic material responses and device‐level photonic functions. This Review highlights how azobenzene research has evolved from molecular photochemistry to photoalignment, mass migration, photomechanics, and heat release, ultimately enabling holography, reconfigurable ...

Potential and prospects of reductases in azo dye degradation: a review

The Microbe
Synthetic dyes, particularly azo dyes, pose environmental and health risks because of their toxicity and persistence. To reduce these negative effects, it is necessary to degrade and detoxify these dyes into simple, non-toxic substances.

Inductively Expandable Supraparticles as Microscopic Force Generators for Remote Mechanical Actuation

Advanced Materials, EarlyView.
This study demonstrates the combination of magnetic nanoparticles and functional blowing agents into supraparticles. Upon induction heating, they actuate via rapid gas generation or extensive volume expansion. These supraparticles lift up to 25 000 times their own mass and rapidly open cured epoxy resins, providing a versatile strategy for fast micron ...

Defect‐Driven Charge Separation in Ba‐Doped SrTiO3: Correlating Photoelectrochemical Performance With Dye‐Selective Photocatalysis

Advanced Materials Interfaces, EarlyView.
Ba‐doped SrTiO3 perovskites establish a direct correlation between photoelectrochemical activity and photocatalytic performance. Optimized Ba0.5Sr0.5TiO3 exhibits enhanced charge separation, photocurrent generation, and visible‐light‐driven dye degradation through defect‐induced oxygen vacancies and lattice distortion.
