Summary: The study found that iron mineral-driven reduction of NO3- or NO2- in experiments containing NOx- could not provide sufficient NH3/NH4+ to form amino acids, requiring an exogenous source of NH3/NH4+. Additionally, NO2- was observed to react with Fe2+ and Fe(II) minerals, leading to Fe oxidation and the formation of oxidized mineral phases.

Summary: This study successfully used Fe-BC-Cu filler synthesized from waste Lycium barbarum L. branches to treat oil refinery water, achieving maximum COD and TOC removal efficiency of 77.11% and 68.71% respectively under optimal conditions of initial wastewater pH of 4.0, Fe-BC ratio of 1:1, and Fe-BC-Cu ratio of 1:1:1. Reusability tests showed that the COD removal efficiency remained at around 80% over 10 cycles. Heavy metal analysis of the effluent indicated no risk of heavy metal release, and the micro-electrolysis filler showed extraordinary potential for industrial applications.

Summary: Layered transition metal molybdates (LTMs) are proposed as slow-release fertilizer compounds for micronutrients molybdenum (Mo), zinc (Zn), and copper (Cu). LTMs were successfully prepared and characterized, and their solubility in water was tested. The LTMs showed limited stability in acidic conditions, so co-compaction with pH neutral or alkaline macronutrient carriers was explored. A Zn-based LTM co-compacted in a muriate of potash (MOP) carrier showed a slow and constant release rate of both Mo and Zn, making it a potential slow-release fertilizer or raw material for non-acidic fertilizers.

Summary: In this study, selective sequential extraction and microanalysis methods were used to investigate the distribution and occurrence modes of arsenic in phosphate ore. It was found that arsenic mainly existed in carbonate minerals, oxides/hydroxides, and sulfide minerals fractions, with a small portion in the exchangeable and soluble fraction. Microanalysis revealed that iron oxides/hydroxides, rhodochrosite particles, and pyrite were the main arsenic-containing minerals. These findings provide valuable insights for developing techniques to remove arsenic from phosphate ores.

Summary: The slow kinetics of the oxygen evolution reaction (OER) hinders the progress of water electrolysis technology and the long-term efficiency of hydrogen energy production. By creating a self-supported electrode with FeS film coated Fe foam as a substrate, ordering resoluble molybdate (MoO42-) anions in interlayers, and codoping as a catalytically active phase, an electrochemically self-reconstructing (ECSR) catalyst for OER is developed. The catalyst introduces new active sites through the dissolution of molybdate and sulfur ions, resulting in improved OER activity and stability.

Summary: This study provides insights into the influence of sulphate addition on the glass forming properties of SiO2-P2O5-K2O-MgO/CaO/MgOCaO systems. The results show that only the system containing MgO can obtain amorphous materials. The addition of SO3 increases the glass transformation temperature and decreases the vitreous state transformation range and onset of the crystallization process. The precipitate K2SO4 exists in the studied materials regardless of the composition of the base glass.

Summary: The synthesis method used allows for uniform deposition of both large and small Fe2O3 nanoparticles on the surface of TiO2. Analysis confirms the presence of anatase TiO2 and hematite Fe2O3 in the heterostructure. The TiO2@Fe2O3 heterostructure exhibits enhanced photocatalytic activity compared to pure titanium and iron oxides. The magnetic properties and optical transitions in nanometric Fe2O3 are influenced by the size of the Fe2O3 particles on the surface of TiO2 nanocrystals.

Current strategies to reduce this issue often fail when particle size is reduced. This study analyzed the curing and debinding behavior of magnesium aluminate spinel in different acrylates and methacrylate, and evaluated the strategy of reducing exothermal effects through the addition of propylene carbonate.

Summary: A series of TiO2-based catalysts were designed with tungstophosphoric acid (HPW), alone or with Fe2O3 addition. These HPW@Fe2O3@TiO2 nanocomposites showed satisfactory catalytic performance in the dehydration of n-butanol under both thermocatalytic and photothermocatalytic conditions. The highest catalytic activity was achieved over HPW/hp, HPW/Fe/hp, and HPW/T805. The main product was found to be cis-butene, along with trans-butene, di-n-butyl ether (DNBE), and butyraldehyde.

Summary: This paper presents the synthesis and properties of nanometric TiO2 powders obtained by the sol-gel method at elevated temperatures. The presence of brookite inhibits the anatase-rutile transformation at higher temperatures. Even after the treatment of gel at 700 degrees C, a large amount of anatase in the TiO2 powders was found. Measurements in the UV-vis range were performed to determine the optical band-gap of TiO2. Results of photocatalytic tests for the degradation of RhB and NO under UV are also presented. The obtained powders despite being prepared at this temperature were more efficient in both RhB and NO decomposition compared to the reference sample. The results indicate the possibility of modifying materials that are produced or work at high temperatures, by adding TiO2 with high photocatalytic capacity in the UV range.

Summary: SiCO coated AISI 301 steel with different molar mass polysiloxane precursors (C1, C2, C3) was prepared by pyrolysis. The oxidation behavior of SiCO coated AISI 301 substrates was studied at 900 degrees C for 100 h. The SiCO coated steel exhibited better performance (kp similar to 10(-13) g(2)cm-4s(-1)) compared to the uncoated steel (kp similar to 10(-12) g(2)cm(-4)s(-1)) due to the formation of dense and well-adherent coatings. The molecular weight of the polymer did not affect the thickness or protective properties of the layers. An attempt was made to investigate the oxidation mechanism of the SiCO layer through a marker experiment.

Summary: This paper presents the optimization of the sintering process of Ti6Al4V powders using SPS and the study of the impact of graphene oxide (GO) on this material. The effect of adding GO to Ti6Al4V was determined and optimal mixing parameters were selected based on the homogeneity of carbon distribution determined by X-ray spectrometry. Tests using SEM, TEM, and Raman spectrometry techniques were performed to identify the phase boundaries between Ti6Al4V and GO. The results showed that the addition of GO strengthens Ti6Al4V and the proposed method is effective in strengthening the Ti6Al4V alloy.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: This study explores the potential of biphenylene as a nanocarrier for the delivery of the anticancer drug cisplatin. It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.

The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
