Wet-chemical preparation and physicochemical characterization of nanostructured Zn-Bi2O3/CeO2 composite: A visible-light-driven catalyst for the annihilation of pharmaceutical pollutant

A modified co-precipitation technique assisted with cetyltrimethylammonium bromide (CTAB) surfactant was used to synthesize a nanostructured and zinc-doped mixed metal oxide (Zn-Bi2O3/CeO2) composite. Using X-ray diffraction (XRD), the synthesized nanocomposite was studied in terms of its crystal structure, grain size, percentage crystallinity, and percentage porosity. Energy dispersive X-ray elemental analysis (EDX) was used to ascertain the chemical composition, SEM to confirm the creation of nanostructure material, and Fourier transform infrared spectroscopy (FTIR) to extract the existing functional groups. Investigation of light harvesting properties (UV/Vis) and thermogravimetric analysis (TGA) reveals that the doped composite exhibits a band gap driven by visible light and remarkable thermal stability at high temperatures. The pH value at which a material's net charge is zero, known as pHpzc, is 7.93 for the doped mixed metal oxide composite. The Zn-Bi2O3/CeO2 nanocomposite effectively eliminates 98.4 percent of the quinolone antibiotic (levofloxacin) via a mechanism that integrates sorption and photocatalytic degradation induced by visible light. To determine the optimal circumstances for the efficient operation of a photocatalyst, we experimented with different time intervals, beginning drug concentrations, catalyst dosages, operating temperatures, and pH levels. Reusability tests and post-activity FTIR analysis were used to investigate the long-term usability and structural stability of the newly developed doped composite photocatalyst. The scavenging tests revealed a potential photocatalytic mechanism to explain the annihilation of the levofloxacin drug on the synthesized catalyst. The physicochemical and photocatalytic evaluations recommend that the assembled integrated material has excellent potential for mineralizing medicinal products in pharmaceutical wastes.

Polymer-stabilized cholesteric liquid crystals with multi-state reversibility for applications in advanced smart adjustable anti-counterfeiting and energy-saving displays

The creation of an anti-counterfeiting material with reflection color, fluorescence, infrared imaging, and electrical property information will increase the level of anti-counterfeiting. However, the creation of such a material has proved to be extremely challenging. In this study, twin anti-counterfeiting labels with intelligently tunable patterns were obtained through a strategy of PMMA loaded chiral molecules via diffusing on the micrometer scale. In order to enhance anti-counterfeiting ability, the multi-mode intelligently modulated advanced anti-counterfeiting material was obtained through the strategy of introducing photo-isomerizing dithienylethene and infrared-shielding Cs0.33WO3 nanoparticles. This material can be reversibly converted into fluorescent, reflected colors, infrared, and electrical characteristic signals. The encrypted information is displayed with red fluorescence under UV light irradiation. Furthermore, the encrypted information can be reversibly displayed and erased under repeated stimulation by voltage and pressure, heating and cooling, UV, visible and near infrared (NIR) light. The aim of our work is to create a simple method to prepare complex patterns of structural and fluorescent color anti-counterfeiting films with the improved anti-counterfeiting capability. Based on this, the strategy of co-doping fluorescent molecules and photochromic molecules in liquid crystals combined with etching technology has realized a multiple anti-counterfeiting mode with a higher level of security. The advanced multiple anti-counterfeiting mode can output encrypted information of multiple states which will greatly improve the level of anti-counterfeiting. In terms of display, we obtained billboards with complex patterns, price intelligently tunable and full-color display by diffusion S5011 in liquid crystals, thus extending their application in the field of electronic shelf labels.

Processing and characterization of waste dolomite dust filled hemp‐epoxy composites

AbstractThe necessity to adapt sustainable development, green chemistry and industrial ecology leads to the creation of newer materials and the utilization of waste. In this context, this work aims at exploring the feasibility of the fabrication of hybrid composites comprised of a polymeric resin reinforced with a natural fiber (hemp) and an industry waste filler (dolomite dust). While the hemp fiber content is kept constant, epoxy‐based hybrid composites are fabricated with different weight percentages of dolomite dust using the conventional hand lay‐up route. The microstructural features of the constituent materials are studied using stereo and scanning electron microscopes which show the shape and size of dolomite particles and the arrangement of fibers. An x‐ray diffraction analysis revealed the presence of hematite, graphite, lime and manganite. The presence of functional groups like hydroxyl, carboxyl and azide is ascertained from the transmittance spectra of Fourier transform infrared spectroscopy. The density and void fractions are increasing with the amount of filler particles in the composite. It is observed that the tensile and flexural strengths of the composites marginally drop with increase in dolomite dust content, but there is a reasonable improvement in their inter‐laminar shear strength, micro‐hardness and impact strength values.

Microplastics originated from Plasmix-based materials caused biochemical and behavioral adverse effects on Daphnia magna

The implementation of advanced recycling techniques represents a key strategy for mitigating the mismanagement and the environmental impact of plastic waste. A limited array of plastic polymers can be efficiently recycled, while a notable portion of plastic waste remains unrecyclable. In Italy, this residual, heterogeneous fraction is referred to as Plasmix. Because of its complexity and non-homogeneous composition, Plasmix is primarily directed towards low-value applications. However, recent developments in laboratory-scale mechanical recycling have enabled the creation of new plastic materials from Plasmix. Prior to their application, these materials must undergo rigorous eco-safety evaluation. The present study aims to assess the potential toxicity of microplastics (MPs) from Plasmix-based materials on the freshwater crustacean Daphnia magna. Specifically, this study investigated sub-individual and individual effects induced by a 21-day exposure to different concentrations of MPs generated from the grinding of naïve and Additivated Plasmix-based materials (hereafter referred to as Px-MPs and APx-MPs, respectively). Sub-individual endpoints focused on changes in oxidative status, including the modulation of antioxidant and detoxifying enzyme activities, as well as oxidative damage, such as lipid peroxidation. Individual level endpoints included alterations in survival and reproduction. Microscopy analyses confirmed the ingestion of both Px-MPs and APx-MPs by D. magna individuals. An oxidative stress condition raised in organisms exposed to Px-MPs, whereas no effect was observed in individuals exposed to APx-MPs. Although survival was not affected, a significant impairment in reproductive output was detected at the end of exposure to all the concentrations of both MP types. These findings suggest that even low concentrations of Px-MPs and APx-MPs could negatively affect the health status of D. magna, underscoring the need for further research to complete the risk assessment of Plasmix-based materials prior to their use in consumer products.

Interface-Interactive Nanoarchitectonics: Solid and/or Liquid.

The methodology of nanoarchitectonics is to construct functional materials using nanounits such as atoms, molecules, and nanoobjects, just like architecting buildings. Nanoarchitectonics pursues the ultimate concept of materials science through the integration of related fields. In this review paper, under the title of interface-interactive nanoarchitectonics, several examples of structure fabrication and function development at interfaces will be discussed, highlighting the importance of architecting materials with nanoscale considerations. Two sections provide some examples at the solid and liquid surfaces. In solid interfacial environments, molecular structures can be precisely observed and analyzed with theoretical calculations. Solid surfaces are a prime site for nanoarchitectonics at the molecular level. Nanoarchitectonics of solid surfaces has the potential to pave the way for cutting-edge functionality and science based on advanced observation and analysis. Liquid surfaces are more kinetic and dynamic than solid interfaces, and their high fluidity offers many possibilities for structure fabrications by nanoarchitectonics. The latter feature has advantages in terms of freedom of interaction and diversity of components, therefore, liquid surfaces may be more suitable environments for the development of functionalities. The final section then discusses what is needed for the future of material creation in nanoarchitectonics.

The study aims to critically analyze the potential use of structural elements made of ferromagnetic materials with a second-kind phase transition temperature (Curie temperature or Curie point) in high-performance, knowledge-intensive industries, particularly the chemical industry. These materials correspond to the required temperature of the processed or transported liquid or loose medium. The technological processes using the magnetothermal effect and the corresponding designs of equipment are considered: heat exchange, heat and mass exchange, mechanical and hydromechanical, equipment for processing thermoplastics, as well as other devices used in various branches of industry, in particular chemical, food and microbiological, in thermal energy, metallurgy, agriculture, medicine and construction. It is shown that the specified method of ensuring the required thermal regime is suitable for use primarily in large-tonnage continuous production. As the conducted studies have shown, the proposed approach to stabilizing the heat flow of various technological and auxiliary equipment is effective and quite promising. The indisputable advantage of the corresponding method is to ensure a certain temperature of the working parts of the equipment with high accuracy, however, this method is quite difficult to implement on the existing equipment, which is mostly made of magnetic materials (steel, cast iron). Therefore, to implement the proposed method in practice, it is necessary to develop new equipment designs or to subject existing samples to deep modernization. At the same time, there may be difficulties associated with the search for existing or the creation of new ferromagnetic materials with the required thermomagnetic properties for the manufacture of appropriate structural elements of technological and auxiliary equipment. However, in certain cases, the proposed method of maintaining the specified temperature of the processed media may become the most appropriate (primarily in fine chemical technology, biotechnology, pharmaceuticals, precision instrument manufacturing, microelectronics, and medicine).

Breeding peculiarities of the manifestation of hemp fiberness signs

Aim. To establish the genetic features of the manifestation of signs of fibrousness and yield of stems, depending on growing conditions and harvesting periods. Methods. New methods were applied: "Method of evaluation of hemp plants for the presence of cannabinoids", "Method of evaluation of individual plants of monoecious hemp varieties by fiber content at the beginning of flowering", "Method of creation of hybrid breeding material of monoecious hemp". Results. It was established that the main conditions for obtaining the maximum amount of fiber and its quality indicators are the use of the late-ripening variety Hlukhivski 51, sowing with a feeding area of 15x5 cm, the diameter of the stems 6-8 mm, the sowing rate of 75 kg/ha (4.2 million pcs./ha) against the background of increased fertilization. Conclusions. The genetic features of the Hlukhivski 51 variety are high fibrousness and high yield of the stems, which are maximally manifested by observing the conditions of the feeding area of 15x5 cm, the sowing rate of 75 kg/ha (4.2 million pieces/ha) and the increased background of fertilization (N120P90K90). Expansion of the response of genotypes of late-ripening varieties to the level of dry biomass yield of 20 t/ha occurs with a feeding area of 50x5 and 50x10 cm and increased doses of N150P120K120 fertilizers. This can become the basis for the use of hemp for bioenergy purposes. When growing production crops for fiber in order to speed up harvesting, an important factor is the start of harvesting at an earlier time, and therefore we recommend growing two varieties of hemp: early-ripening (technical maturity occurs 2 weeks earlier than late-ripening varieties) and late-ripening varieties of hemp.

Enhanced piezoelectric properties of additively manufactured BCZT with an oriented ceramic lamellar structure formed via vat photopolymerization

Advances in additive manufacturing have enabled the creation of piezoceramic materials with complex architectures. However, the lack of a clear structural design strategy limits their performance and application in high-performance piezoelectric transducer devices. This work outlines the additive manufacture of a novel sandwich architecture based on a porous (Ba0.85Ca0.15)(Zr0.1Ti0.9)O3 (BCZT) layer containing oriented ceramic lamellae. The d33 charge coefficients and g33 voltage coefficients of the optimized porous ceramic were 1.16 times and 2.11 times higher than those of the dense counterparts respectively. After electroding the aligned lamellar ceramic with an indium tine oxide film a piezoelectric sensor was obtained which, when subject to a pressure of 7.5 MPa, produced a open circuit voltage of 173 V. This paper provides a new structural design strategy to effectively improve the performance of piezoelectric ceramics, and provides new opportunites for the design and production of additive manufactured piezoelectric sensors and energy harvesting devices.
