Summary: Through pot experiment, we investigated the detoxification and tolerance mechanism of cadmium (Cd) in barley. The results showed that barley reduces the toxic effects of Cd by storing it in the roots and reducing its transport to the shoots. The conversion of Cd into less toxic forms, such as pectates and protein-integrated Cd, is mainly due to its combination with specific functional groups. Excessive Cd damages the cell membrane, organelles, and metabolism of intracellular substances, leading to toxicity symptoms.

Summary: Fibers are essential for product development and can be categorized into synthetic and natural types. Emerging nanotechnology has significantly contributed to the advancement of next-generation fabrics by providing unique properties such as higher conductivity and self-cleaning capabilities. Two cotton samples modified with titanium dioxide and zinc oxide were examined using various techniques, demonstrating that nano-coated fiber samples can be differentiated at 365 nm under UV light.

Summary: Simultaneous sulfur+phosphorus poisoning on platinum-based diesel oxidation catalyst significantly affects catalyst activity by blocking adsorption sites for sulfur species on alumina and leading to sulfur mainly adsorbing on cerium oxides, while remaining with and near platinum particles to block active sites.

Summary: The phase-structural composition of silica films grown on Si substrates implanted with different fluences of Zn ions has been studied using TEM and electron diffraction. Small and larger clusters were formed in the as-implanted silica films with Zn concentration of 6-8 at% and 16-18%, respectively. Furnace annealing at 750°C resulted in the formation of orthorhombic Zn2SiO4 phase for low fluence and the formation of zinc blended ZnO phase for high fluence.

Summary: The vault nanoparticle is a eukaryotic assembly consisting of 78 copies of the 99-kDa major vault protein. It is involved in pro-survival and cytoprotective functions, and has great potential for drug/gene delivery due to its large internal cavity and lack of toxicity/immunogenicity. A simplified purification procedure for vaults was developed, combining expression in the yeast Komagataella phaffii and a size-exclusion chromatography purification process. The protein's aggregation tendency was investigated, and suitable storage conditions were determined to maintain it in its native, soluble form.

Summary: The effect of ethanol concentration on the ionization degree of xylan and chitosan, as well as the properties of polyelectrolyte complex suspensions and derived films, was studied. Increasing ethanol concentration led to changes in particle sizes, z-potential values, and crystallinity of films. The stress at break of the films increased, while the swelling capacity decreased favorably.

Summary: This study found that extracts from Senna alexandrina leaves demonstrated antifungal activity against certain phytopathogenic fungi, but were ineffective against Candida spp. The extracts caused damage to cell morphology at MIC concentrations. Methanol and aqueous extracts may target plant pathogens by affecting fungal cell morphology and structure.

Summary: Goose liver oil microcapsules prepared with konjac glucomannan and soybean protein isolate exhibited high encapsulation efficiency and improved thermal and oxidative stability compared to free goose liver oil. The microcapsules showed a smooth spherical surface morphology and homogeneous internal structure. They also demonstrated good gastric juice permeability and controlled release in the intestinal region.

Summary: The study demonstrates that aging of metal-oxide nanoparticles in soil significantly enhances metal uptake by plants, leading to impacts on biomass accumulation and chlorophyll formation in cucumbers. This highlights the importance of careful consideration when using aged metal-oxide NPs for agricultural purposes, especially with essential and non-essential metals interacting with cucumber plants.

Summary: This study investigates the metal tolerance and biosorption characteristics of four bacterial strains isolated from Saint Clair River sediments. The findings suggest that metal tolerance does not necessarily determine metal removal efficacy. The study highlights the metal-binding capabilities of the strains through Fourier-transform infrared analysis and reveals metal accumulation and morphological changes through microscopy techniques. The species-specific differences in metal accumulation strategies are also discussed.

Summary: Understanding morphological changes of nanoparticles in solution is crucial for tailoring the functionality of energy devices. However, there is a lack of experimental methods that can visualize these processes in solution and provide three-dimensional information. This study demonstrates the use of X-ray ptychography for in situ 3D imaging of the formation and hollowing of nanoparticles in solution at high temperature.

Summary: This study successfully demonstrated the in situ controlled synthesis of alloyed AuCu nanocrystals under LP-TEM, while maintaining the molecular structure of metal thiolate complexes. The research revealed that polymer capping ligands not only have known functions during LP-TEM synthesis, but also prevent copper oxidation and facilitate the formation of prenucleation cluster intermediates.

Summary: The physicochemical characteristics of particulate matter produced by PODE2-4/diesel blended fuel at different blend ratios were characterized. Increasing PODE2-4 concentration decreased PM size and increased fractal dimension. The addition of PODE2-4 affected the nanostructure and oxidation activity of PM, leading to faster oxidation rates.
