Analysis of the Influence of Pesticides on the Soil in an Agricultural Area
The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2021 The paper presents an analysis of the soil in an agricultural area, to determine the influence of pesticides on the soil where agricultural production is carried out. For the research of the soil quality, were analysed areas, for harvesting soil samples.

Morphological analysis of ultra fine α-MnO2 nanowires under different reaction conditions [PDF]
Materials Letters, Volume 158, 1 November 2015, Pages 309-312, 2018 A simple hydrothermal method was developed for the synthesis of ultra fine single-crystal {\alpha}-MnO2 nanowires by only using potassium permanganate and sodium nitrite in acidic solution, without any seed or template. Detailed analysis of the obtained nanowires was done using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and

Imine Crosslinked, Injectable, and Self‐Healing Fucoidan Hydrogel with Immunomodulatory Properties
Advanced Healthcare Materials, EarlyView.This study develops an injectable fucoidan‐based hydrogel with tunable properties for tissue engineering. By oxidizing fucoidan (OFu) to introduce aldehydes, imine crosslinks are formed with amine‐containing polymers, enabling self‐healing, injectability, and long‐term stability (≥28 days). The OFu‐gelatin hydrogel demonstrated biocompatibility, immune‐

Light‐Activatable Hyaluronic Acid‐Derivatives Releasing Nitric Oxide and Their Delivery in the Skin
Advanced Healthcare Materials, EarlyView.This work explores the development of photoactivatable hyaluronic acid (HA) derivatives functionalized with nitric oxide (NO) photodonors for light‐controlled therapeutic applications. The HA derivatives demonstrate enhanced keratinocyte proliferation and migration, effective NO release, and skin penetration when formulated as microemulsions.

Superstatistical approach to air pollution statistics [PDF]
Phys. Rev. Research 2, 013019 (2020), 2019 Air pollution by Nitrogen Oxides (NOx) is a major concern in large cities as it has severe adverse health effects. However, the statistical properties of air pollutants are not fully understood. Here, we use methods borrowed from nonequilibrium statistical mechanics to construct suitable superstatistical models for air pollution statistics.

Advanced Materials Interfaces, EarlyView.This study investigates the impact of nanostructured surface modification on corrosion resistance, HUVEC functions, and platelet interactions of 316L SS for cardiovascular stents. Nanostructured surfaces enhanced HUVEC proliferation, migration, and angiogenesis‐related gene expression while reducing platelet adhesion and hemolysis.

Temperature Evolution of Sodium Nitrite Structure in a Restricted Geometry [PDF]
, 2002 The NaNO$_{2}$ nanocomposite ferroelectric material in porous glass was studied by neutron diffraction. For the first time the details of the crystal structure including positions and anisotropic thermal parameters were determined for the solid material, embedded in a porous matrix, in ferro- and paraelectric phases.
