In this study, the synthesis of composite materials produced from Ni/Al with three types of carbon-based materials namely chitosan (Ch), cellulose (Ce), and graphene oxide (GO) was successfully carried out supported by X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), and Brunauer-Emmett-Teller (BET) analysis. The combined characteristics of the two starting materials are present in the composite material based on XRD and FT-IR data. The surface area of Ni/Al-LDH increased after compositing with Ch, Ce, and GO, from 3.3 m2/g to 9.5 m2/g in Ni/Al-Ch, 5.1 m2/g in Ni/Al-Ce, and 78.4 m2/g in Ni/Al-GO. These findings indicate that the materials are suitable for various applications such as photocatalytic and adsorption as effective materials in further research.

Titanium is widely recognized as the most biocompatible metal due to the inert passive oxide layer that forms spontaneously on its surface. However, dental implants made of titanium and its alloys remain susceptible to corrosion when exposed to saliva for extended periods in the oral environment. Additionally, the presence of alloying elements in the alloy may raise concerns about potential toxicity concerns upon release into the human body. Consequently, there is an increasing need for research aimed at improving the mechanical properties and biocompatibility of dental implants made from both commercially pure titanium (CP Ti) and Ti alloys. This article provides a review of recent publications that investigate the impact of grain size reduction on ultrafine-grained and nanocrystalline CP Ti and Ti alloys. The article explores the modification of the oxide layer to nanotube TiO2 and its influence on corrosion resistance. The analysis of accumulated data provides a comprehensive understanding of the mechanisms underlying corrosion resistance improvement, offering valuable insights into the crucial directions for future research in this field.
钛因其表面自发形成的惰性被动氧化层而被公认为生物相容性最好的金属。然而，由钛及其合金制成的牙科植入体在口腔环境中长期暴露于唾液中时，仍然容易受到腐蚀。此外，合金中存在的合金元素可能会引起人们对其释放到人体后的潜在毒性的担忧。因此，人们越来越需要开展研究，以改善由商业纯钛（CP Ti）和钛合金制成的牙科植入体的机械性能和生物相容性。本文综述了最近发表的研究晶粒尺寸减小对超细晶和纳米晶 CP Ti 和 Ti 合金影响的文章。文章探讨了氧化层对纳米管 TiO2 的改性及其对耐腐蚀性的影响。通过对积累的数据进行分析，可以全面了解耐腐蚀性能改善的内在机制，为该领域未来研究的重要方向提供有价值的见解。

The selectivity analysis of anionic dye adsorption by E. cottonii macroalgae has been successfully conducted in this study. Selectivity analysis encompassed congo red, direct yellow, methyl orange, and direct green dyes with measurements taken at 0, 2, 4, 6, 8, and 10-minute intervals. The dye concentration was standardized at 50 g/mL, and 20 mL of each dye solution was utilized. Variations in absorbance were assessed using a UV-Vis Spectrophotometer, revealing that E. cottonii exhibited the highest selectivity for methyl orange. Characterization through FT-IR indicated the presence of O-H, C-H aliphatic, C=N, C=C, C-O, and N-H bonds in the dried E. cottonii macroalgae material. These results affirm the superior selectivity of E. cottonii in adsorbing methyl orange, as demonstrated by the selectivity test.

This experimental inquiry delves into the evaluation of compressive and flexural strengths in concrete through the utilization of waste glass powder as a partial substitute for cement. Compressive strength is a key metric, indicating the concrete’s ability to effectively support structural axial loads, while flexural strength signifies its capacity to withstand deformation under bending, specifically the maximum tensile stress it can endure without fracturing when subjected to a bending moment. Certain pozzolanic materials have demonstrated the ability to enhance the mechanical strength of concrete when used as a cement replacement, and waste glass powder is among them. To address this, the experimental investigation included the substitution of cement with glass powder at different proportions (0%, 10%, 15%, 17.5%, and 20%) in both cubic and prismatic samples. Compressive strength and flexural strength tests were made following the curing of the samples for 7, 14, and 28 days. The findings indicated that the 17.5% cement replacement level exhibited a 6.07% over-strength for compressive strength and a 6.85% over-strength for flexural strength on the 28th day. However, the 15% replacement showed superior strength compared to a 10% replacement, and the 10% replacement was stronger than a 0% cement replacement. Notably, the 20% cement replacement displayed negative over-strength percentages, specifically -2.42% in compressive strength and -1.42% in flexural strength on the 28th day. This deviation raises concerns about its suitability for use in concrete applications, signifying that a 20% replacement may not be recommended.

This study investigates the selective adsorption capabilities of Ni/Al Layered Double Hydroxide (LDH) modified withEucheumacottoniifor the removal of cationic and anionic dyes from aqueous solutions. The primary objective was to evaluate the efficiencyand selectivity of these modified adsorbents towards different dyes, including rhodamine-b, malachite green, methylene blue(cationic dyes), and direct yellow, methyl orange, direct green (anionic dyes). The modification process aimed to enhancethe adsorption properties of LDHs, leveraging the natural adsorption capabilities ofEucheuma cottonii. Experimental resultsdemonstrated significant differences in adsorption percentages among the tested dyes, with malachite green showing thehighest adsorption efficiency among cationic dyes, indicating a strong affinity of the modified adsorbents towards cationic dyes.However, the ability to also adsorb anionic dyes suggests the dual-functionality of the modified LDHs, making them versatileagents for dye removal in water treatment applications.

Catalyst material (M2+)Al-LDH was successfully prepared in this study. Characterisation analysis by XRD and FTIR. XRD analysis of Zn/Al-LDH, Mg/Al-LDH and Ni/Al-LDH showed agreement with pure LDH as seen from the JCPDS data and showed crystal forms similar to hydrotalcite, brucite and hydrotalcite respectively. FTIR analysis of the (M2+)Al-LDH material showed the presence of functional groups which explain the presence of O-H stretching, O-H bending, CO32- bonds and identified metal oxide (MO) groups from the synthesised LDH. (M2+)Al-LDH has the ability to act as a catalyst for excellent desulphurisation of 4,6-dimethyldibencothiophene with % conversion value above 90%. In addition, (M2+)Al-LDH is a heterogeneous and reusable catalyst.

This study employed two alloys of AISI (316,304) Stainless steel to improve the mechanical characteristics. In addition, the corrosion rate achieved by pulse laser deposition (PLD) can be reduced by applying a ZnO coating. Zinc oxide has garnered significant interest. Biomaterials have long been well-acknowledged for their use in dentistry and medical applications. Using an optical microscope examined the coating morphology, scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS). The corrosion protection has been examined by assessing the mechanical characteristics when submerged in saliva with a pH of 5.6. The surface alteration is assessed using roughness and microhardness measurements. The corrosion resistance of all samples is superior to that of bare AISI (316,304) stainless steel.

The complex compound tetrakis(N,N’-diethylthiourea)bis(isothiocyanato)nickel or [Ni(detu)4(NCS)2] (denoted as UMCC-1) has been synthesized by reflux method in two different solvents namely acetone and methanol. This study aims to synthesize, characterize, and analyze the Hirshfeld Surface complex UMCC-1, which was obtained using the reflux method with the mole ratio of NiCl2: detu: KSCN is 1:2:4. Single crystals UMCC-1 in acetone and methanol are dark green in color with melting points of 135-137°C and conductivity of 66.4-84.4 µS. The FTIR absorption band analysis of the two crystals is very similar, ν(C S) detu 590 cm−1 and ν(C≡N) isothiocyanate 2119 cm−1. The refinement of the crystal structure from the single crystal XRD data shows that the two dark green crystals are a molecular type that has a distorted octahedral geometry with the same crystal lattice, monoclinic crystal lattice, P21/c1 space group (no.14), crystal lattice parameter a= 11.112(3) Å, b= 17.249(5) Å, c= 9.647(3) Å, and β= 100.785(10). However, the complex produced in acetone solvent has better refinement quality than methanol concerning %R= 3.27 and %R = 4.55, respectively. The UMCC-1 crystal shows intermolecular hydrogen bonds N-H---S(isothiocyanato) and intramolecular hydrogen bonds N-H---S(detu) with Hirshfeld Surface analysis showing a significant contribution of H---H (69.5%) on crystal packing.

This research conducted a composite of Ca/Al and Mg/Al Layered double hydroxide with Biochar material using co-precipitation method. Characterization results were carried out with various analyses including XRD, FT-IR, and BET. The results of XRD analysis on Ca/Al-BC showed peaks at 10-11° and 22°, while the Mg/Al-BC material showed peaks at 11. 41° (003), 22. 95° (002), 34. 05° (012) and 60.2° (116). The FT-IR analysis showed that Ca/Al and Mg/Al LDH materials composited with Biochar have functional groups of -OH, nitrate ions, C=O, C-H, C-O, and M-O. BET analysis results show an increase in surface area in Ca/Al and Mg/Al LDH materials after composite with biochar from 29.333 m2/g to 158.291 m2/g in Mg/Al-BC, while in Mg/Al-BC there is an increase from 23.150 m2/g to 111.404 m2/g. The Ca/Al-BC and Mg/Al-BC composite materials have better stability than Ca/Al and Mg/Al LDH materials that can be used up to the fifth cycle. Hydrogen bonding and π-π interaction between the adsorbent and the aromatic ring on phenol can affect the adsorption process.

We conducted this research to modify NiAl layered double hydroxide with several carbon-based materials, including cellulose, biochar and graphite. This material was successfully prepared by coprecipitation methods and was proven by XRD, SEM and FTIR characterization. Furthermore, we conducted the adsorption process and reusability to investigate their ability as water treatments. The dose effect on M.G. removal was investigated by the highest M.G. removal capacity using the CBC-NiAl LDHs composite, which was 100 mg. M.G. removal capacity was increased with an increase in contact time, and the saturation point was reached after 60 min for CC-NiAl and CGF-NiAl LDHs, which CBC-NiAl LDH increased and saturated after 100 min with high adsorption capacity. CC-NiAl, CBC-NiAl and CGF-NiAl LDHs composite have proved efficient, sustainable materials that maintain adsorption capability in each reusable cycle.

CC-NiAl, CBC-NiAl and CGF-NiAl LDHs composite have proved efficient, sustainable materials that maintain adsorption capability in each reusable cycle.","PeriodicalId":170983,"journal":{"name":"Indonesian Journal of Material Research","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139212154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
