Ligand Assisted Epitaxial Growth of CsPbBr3 Microcrystal Resonators With Record ‐Low Lasing Thresholds

Advanced Functional Materials, EarlyView.
Solution‐based ligand‐assisted epitaxial growth (LAEG) yields high‐quality CsPbBr3 microcrystals on different substrates with superior morphology, passivated surfaces, and high photoluminescence quantum yield. These robust micro‐resonators achieve record‐low room‐temperature lasing thresholds of 7.2 kW·cm−2 and maintain operational stability up to 90 ...

Heavy metal biosorption sites in Penicillium cyclopium

Journal of Applied Sciences and Environmental Management, 2006
The biomass of Penicillium cyclopium was subjected to chemical treatment to study the role of the functional groups in the biosorption of heavy metal ions. The modifications of the functional groups were examined with infrared spectroscopy.

3D‐Printed Gradient Shape‐Memory Strain Sensors With Rewritable Gauge Factors

Advanced Functional Materials, EarlyView.
A 3D‐printed shape‐memory strain sensor combines thermomechanical programming with gradient architectural design. Preset strain rewrites the gauge factor (GF), while the gradient geometry amplifies the response through strain redistribution. Reprogrammable sensitivity enables the same sensor to detect weak pulse signals and monitor large‐amplitude ...

Absorption of heavy metals present in food/water containers with nucleotides in safe sustainable solvents

Sustainable Chemistry for Climate Action
Heavy metal deposition poses a serious risk to climate change and ecosystem survival. Bio accumulation of heavy metals is chronic to various body organs and tissues. Heavy metal exposure mainly occurs through food and water. Heavy metals used in food and

Wet Deposition of Heavy metals in Suwon Area

Korean Journal of Environmental Agriculture, 2007
This experiment was conducted to investigate the distribution and burden characteristics of heavy metals in the rainwater sampled at Suwon area, in the middle part of Korea, from April 2002 to October 2003. The relationship between concentration of heavy metal and other chemical properties in the rainwater was also evaluated. Chemical properties in the

Magneto‐Ionic Devices With Polymer‐Based Electrolytes

Advanced Functional Materials, EarlyView.
Polymer electrolytes are introduced for magneto‐ionic devices based on hydroxide and hydrogen ions. The magneto‐ionic effect results in a pronounced voltage‐controlled variation of coercivity in both devices. The switching speed is in the range of 100 ms.

Does heavy metal deposition affect nutrient uptake by moss Pleurozium schreberi?

E3S Web of Conferences, 2013
Heavy metals may influence chemical composition of plants, and thus shape elemental stoichiometry of plant communities. That is because some physiological processes aiming at neutralization of contaminant toxicity require increased acquisition of some ...

Preparation of High-Entropy Alloy by Electrospinning and Its Application in Electrochemical Sensing for Detection of Heavy Metal Ions in Vegetables and Fruits [PDF]

Shipin Kexue
In this study, electrospinning was used to connect carbon nanofibers (CNFs) with multiple metals. Then, through high-temperature graphitization technology, uniformly sized high-entropy alloy nanoparticles (HEA NPs) were successfully synthesized in situ ...
