Abstract The aim of the study is to investigate the relationship between the physico‐chemical properties of superparamagnetic iron oxide nanoparticles ( SPION s) and their cytotoxicity profile in light of their potential biomedical application as nanocarriers for pancreatic cancer treatment. Two types of SPION s were…
Abstract One application of nanocopper is as a wood-preserving pesticide in pressure-treated lumber. Recent research has shown that pressure-treated lumber amended with micronized copper azole (MCA), which contains nanosized copper, releases copper under estuarine and marine conditions. The form of copper released (i.…
Changes in the polymer properties of poly(lactic acid) (PLA) fibers during drawing and degradation processes were analyzed using solid-state NMR, with the goal of elucidating morphological changes that influence fiber tensile properties. Combination of X-ray diffraction (XRD) and differential scanning calorimeter (DSC…
to titanium dioxide nanoparticles (TiO₂ NPs). The different algae age was obtained by changes in flow rate of continually stirred tank reactors prior to NP exposure. Increased algae age led to a decreased growth, variations in chlorophyll content, and an increased lipid peroxidation. Increased initial algae population…
Abstract Toxicity of silver nanoparticles (AgNPs) to benthic organisms is a major concern. The use of AgNPs in industry and consumer products leads to increasing release of AgNPs into the aquatic environment—sediments being the major sink. Effects of sediment pH on the toxicity of AgNPs to benthic oligochaeta Lumbricu…
Abstract Hydrolysis of the phosphate triester tris‐2‐pyridyl phosphate is catalyzed upon complexation with Cu 2+ , with enhancements of the order of 10 7 ‐fold in comparison to the spontaneous hydrolysis of the substrate. Experimental and theoretical results suggest that Cu 2+ most probably coordinates to the nitrogen…
Nacre is a complex biomaterial made of aragonite-tablet bricks and organic mortar that is considerably resilient against breakage. Nacre has been studied with a wide range of laboratory techniques, leading to understanding key fundamentals and informing the creation of bio-inspired materials. In this article, we prese…
We investigated the composition and surface energy characteristics—the surface free energy, its acid‐base and dispersive components, acid and base parameters (according to the van Oss–Chaudhury–Good method), and acidity parameter (according to the Berger method) of composite materials based on the ethylene‐vinyl aceta…
The purpose of this work is to create and examine the mechanical properties of an eco-friendly, low-cost natural fiber filled with glass-fiber-reinforced polymer composite. Cotton shell (CS) particles are a less expensive natural fiber material that can be used as filler, integrated with glass fiber in epoxy-resin mat…
ABSTRACT Polyimine vitrimers are known for their malleability, which endows these materials with properties such as self‐healing, recycling, and reshaping. To enhance the mechanical properties of the polyimine vitrimers, composites were fabricated by incorporating amine‐functionalized TiO 2 microspheres (amTiO 2 MS) i…
Liquids confined between two parallel plates can perform the function of transmission, support, or lubrication in many practical applications, due to which to maintain liquids stable within their working area is very important. However, instabilities may lead to the formation of leaking drops outside the bulk liquid,…
ABSTRACT Herein, we used an electrospinning process to develop nanofibers based on poly‐cyclodextrin. This article describes a simple and effective method to produce fibers of a water‐soluble hyperbranched polymer based on β‐CD and pyromellitic dianhydride via electrospinning. The obtained fibers were made insoluble i…
High‐resolution computed X‐ray tomography (XCT) is applied in this study to characterize the microstructure of Molten Carbonate Fuel Cell (MCFC) cathodes after operation, where a “virgin cathode” formed by porous nickel has been in situ oxidized and infiltrated by liquid electrolyte. This technique extends state‐of‐th…
Porphyrin–trimethyl‐β‐cyclodextrin (TMe‐β‐CDx) complexes have pseudorotaxane structures in which two meso ‐phenyl and/or ‐pyridyl moieties penetrate the upper rim of two TMe‐β‐CDx molecules. Porphyrin derivatives with one to three pyridyl moieties at meso positions formed complexes with TMe‐β‐CDx in which the penetrat…
The synthesis of a novel ordered liquid crystalline epoxy carbon composite was presented in this article. Anthracite thermally modified at 2,000°C (SV2000) having graphitic structure was used as a filler in the composite with matrix obtained by crosslinking a liquid crystalline diepoxy monomer LCEM containing triaroma…
Pesticide resistance and environment threat due to injudicious use of chemical pesticides for disease management employs the alteration in management practices. Chitosan, a deacetylated chitin derivative, behaves like a general elicitor, inducing a non-host resistance, and prime the plants for systemic acquired resist…
This study attempts to improve mechanical and material properties by incorporating hybrid fillers of rice bran carbon (RBC) and modified fumed silica (SiO 2 ). The composites of solution‐polymerized styrene butadiene rubber (SSBR) filled with RBC and SiO 2 were prepared via a mechanical mixing method. The effect of Si…
ABSTRACT Green electrospinning technique was employed to prepare chloroacetated natural rubber (CNR)/poly(vinyl alcohol) (PVA) nanofiber films by varying the addition of PVA in the range 2.5–55 wt % followed by encapsulation of 2.5 wt % fumed silica (FS). In this study, the risk of using organic solvents was eliminate…
Seven‐coordinate Tb III complexes with strong luminescence and thermosensing properties are reported. Mononuclear [Tb(tmh) 3 (PEB)] [tmh: 2,2,6,6‐tetramethyl‐3,5‐heptanedione, PEB: (diphenylphosphoryl)ethynyl]benzene and dinuclear [Tb 2 (tmh) 6 ( m ‐BPEB)] [ m ‐BPEB: 1,3‐bis(diphenylphosphoryl)ethynyl]benzene were cha…
Ultraviolet (UV) light can be used in versatile applications ranging from photoelectronic devices to biomedical imaging. In the development of new UV light sources, in this study, stable UV emission at ≈350 nm is unprecedentedly obtained from carbon nanospheres (CNSs). The origin of the UV fluorescence is comprehensiv…
