Embedding of Laser Generated TiO in Poly(ethylene oxide) with Boosted Li Conduction for Solid-State Lithium Metal Batteries.

Poly(ethylene oxide) (PEO)-based solid polymer electrolytes are considered promising materials for realizing high-safety and high-energy-density lithium metal batteries. However, the high crystallinity of PEO at room temperature triggers low ionic conductivity and Li transference number, critically hindering practical applications in solid-state lithium metal batteries. Herein, we prepared nanosized TiO with enriched oxygen vacancies down to 13 nm as fillers by laser irradiation, which can be coated by in situ generated polyacetonitrile, ensuring good dispersibility in PEO.

Low-temperature CeCoMnO spinel-type catalysts prepared by oxalate co-precipitation for selective catalytic reduction of NO using NH: A structure-activity relationship study.

CeCoMnO spinel-type catalysts for the selective catalytic reduction of NO using NH (NH-SCR) are usually prepared by alkaline co-precipitation. In this paper, a series of CeCoMnO spinel-type catalysts with different calcination temperatures were prepared by acidic oxalate co-precipitation. The physicochemical structures and NH-SCR activities of the CeCoMnO spinel-type catalysts prepared by oxalate co-precipitation and conventional ammonia co-precipitation were systematically compared.

Controlled plasmon-induced nonlinear absorption and optical limiting in Al/PVP composite nanofibers.

The effect of aluminum (Al) concentration on the surface plasmon resonance (SPR) band position of aluminum/polyvinylpyrrolidone (Al/PVP) composite nanofibers was investigated to strengthen nonlinear absorption (NLA) and widen its spectral range. With increasing Al content in PVP nanofibers, the SPR band was shifted towards excitation wavelength and an improved NLA response was achieved. The NLA response was examined both experimentally, by conducting -scan experiments, and theoretically, using two models.

Advancements and sustainable strategies for the treatment and management of wastewaters from metallurgical industries: an overview.

Metallurgy is pivotal for societal progress, yet it yields wastewater laden with hazardous compounds. Adhering to stringent environmental mandates, the scientific and industrial sectors are actively researching resilient treatment and disposal solutions for metallurgical effluents.

Tree-rings analysis to reconstruct atmospheric mercury contamination at a historical mining site.

Mercury (Hg) is a global environmental concern due to its toxicity (especially high in methylated form) and the long-range distribution of its gaseous elemental form (GEM). Hg-contaminated areas, such as abandoned mining sites, pose intrinsic difficulties for their management and heavy monitoring costs. In these environments, plant-based solutions may play a key role in the ecosystem quality assessment and support remediation strategies, combining reliability and cost-effectiveness.

Evolutions of Cube ({001}<100>) and {115}<161> Orientations in Cold-Rolled Ultra-Thin Non-Oriented Silicon Steel.

In this study, the evolutions of Cube and {115}<161> orientations of a cold-rolled ultra-thin non-oriented silicon steel were investigated using a combination of experimental investigation and the crystal plasticity finite element method (CPFEM). The results show that Cube orientations remain relatively stable when their initial deviation angles from the ideal Cube orientation are less than 12°, even after a 60% cold rolling reduction. However, larger deviations occur due to higher strain near grain boundaries.

Lead, Cadmium, and Arsenic in Raw Cow's Milk in a Central Andean Area and Risks for the Peruvian Populations.

Milk and its derivatives are basic foods in Peru, especially for children. The Junín region, in the central Andes, is one of the leading dairy basins. However, the safety of milk is affected by mining-metallurgical activities, wastewater dumping, organic residues, and inappropriate use of organophosphate fertilizers in agriculture whose contaminants reach the food chain, putting human health at risk.

The rapid removal of trace arsenic is crucial for ensuring the safety of drinking water. However, achieving the rapid removal of trace arsenic poses a significant challenge. In this study, we aim to enhance the removal efficiency of trace arsenic by increasing the specific surface area of the adsorbent material while maintaining its micrometer size.

Quality control prediction of electrolytic copper using novel hybrid nonlinear analysis algorithm.

Traditional linear regression and neural network models demonstrate suboptimal fit and lower predictive accuracy while the quality of electrolytic copper is estimated. A more dependable and accurate model is essential for these challenges. Notably, the maximum information coefficient was employed initially to discern the non-linear correlation between the nineteen factors influencing electrolytic copper quality and the five quality control indicators.

Synergy of copper vacancies and amorphous regions in copper sulfides enables superior capacity for Hg adsorption.

Adsorption is a high-efficiency and low-cost approach to control elemental mercury emission from industrial flue gas. However, the adsorption capacity is unsatisfactory due to its surface-only adsorption. In this work, a facile method was used for preparing the crystalline-amorphous co-existed copper sulfides (CA-CuS) with an abundance of copper vacancies and amorphous regions through temperature-controlled ultrasonic cavitation.

An experimental setup and segmentation method for CFU counting on agar plate for the assessment of drinking water.

Quantification of bacterial colonies on an agar plate is a daily routine for a microbiologist to determine the number of viable microorganisms in the sample. In general, microbiologists perform a visual assessment of bacterial colonies which is time-consuming (takes 2 min per plate), tedious, and subjective. Some automatic counting algorithms are developed that save labour and time, but their results are affected by the non-illumination on an agar plate.
