Trends of atmospheric heavy metal deposition in Lithuania

Lithuanian Journal of Physics, 2011
The results of long-term measurements of heavy metal (Pb, Zn, Cr, Ni, Cu, Mn, Cd, Fe, As, Hg) concentrations carried out at the Aukstaitija and Žemaitija integrated monitoring stations (IMS) are presented in this work. The average annual concentrations of heavy metals in the air in 2007–2008 and in precipitation over the period 2006–2010 are analysed ...

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.

Long‐Range Coordination Environment Modulates Single‐Atom Local States and Systemic Impact on CO2 Photoconversion

Advanced Functional Materials, EarlyView.
Terminal groups on Cu porphyrins modulate the electronic states of single‐atom Cu centers through a long‐range electronic effect, without altering the Cu coordination geometry. Meanwhile, a multi‐descriptor framework is established that incorporates porphyrin regulation, hybrid catalyst properties, and CO2 photoreduction capabilities.

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

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 ...

Mechanoluminescent HOF Nanotransducers Enabled Sono‐Optogenetics in Parkinsonian Rats

Advanced Functional Materials, EarlyView.
We present a mechanoluminescent system utilizing porous hydrogen‐bonded organic frameworks (HOFs) as a toolkit for focused ultrasound‐triggered, non‐invasive light delivery to the deep brain in rats. This approach enables the specific activation of PV‐GPe neurons in dopamine‐depleted Parkinson's disease rat models, resulting in a comparable alleviation

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
