A method for regulating the rutile and anatase ratio of TiO 2 products by adding tartaric acid is reported. By this method, TiO 2 with a specific anatase/rutile ratio exhibited excellent selective adsorption performance of 68 Ge and 68 Ga. Experiment shows that Tartaric acid assist synthesized TiO 2 enabled strong 68 Ge adsorption but negligible adsorption of 68 Ga. Meanwhile, the TiO 2 adsorption exhibited significant acid resistance, with minimal Ti 4+ leaching. In addition, the 68 Ga elution efficiency and 68 Ge breakthrough of radioactivity experiments demonstrated that synthesized TiO 2 achieved an initial 68 Ga elution efficiency of 75%, which remained about 65% after 200 elution cycles. Furthermore, over the four-month observation period, the 68 Ge breakthrough of the TiO 2 adsorbent did not exhibit a significant increase, remaining below 1×10 -5 . Generally, the synthesized TiO 2 adsorbent exhibits potential as a 68 Ge/ 68 Ga generator column adsorbent with outstanding acid-resistant, radiation-resistant, efficient 68 Ga elution and low 68 Ge breakthrough for long-term.

The efficient recovery of germanium from complex secondary resources is a significant challenge in resource sustainability. In this study, a tartaric acid-functionalized nitrogen-doped hydrochar (NPB-TA) was synthesized for selective germanium (Ge) capture from aqueous solutions containing other metal ions. Adsorption experiments demonstrated that NPB-TA can be used in germanium solutions of varying pH and concentration, achieving a saturated adsorption capacity of 112.23 mg/g at pH = 3. The adsorption process was found to be in accordance with the Langmuir isotherm and pseudo-second-order kinetic models, indicating monolayer adsorption and chemisorption as the dominant mechanisms. Moreover, NPB-TA exhibited superior selectivity toward Ge (IV) even in binary systems with competing ions. Fourier-transform infrared spectroscopy, X-ray photoelectron spectroscopy, and Density functional theory calculations were applied to elucidate the adsorption mechanism. The mechanism involves synergistic coordination between Ge (IV) and surface-bound -OH/-COOH groups, with amino groups facilitating the formation of stable chelating rings containing C-O-Ge/C-N-Ge bonds. This study demonstrates that tartaric acid-modified N-doped biosorbent has potential for the selective recovery of germanium from aqueous solution.

Cu bismuthate nanosheets have been synthesized by a facile hydrothermal process. The structure and morphology of the nanosheets are analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and high-resolution TEM (HRTEM). Electrochemical performance for the determination of tartaric acid using Cu bismuthate nanosheets has also been analyzed by cyclic voltammetric (CV) method. XRD pattern shows that the Cu bismuthate nanosheets are composed of tetragonal CuBi 2 O 4 phase. Electron microscopy observations indicate that the Cu bismuthate nanosheets have the polycrystalline structure with the thickness of about 50 nm and width of 300 nm-2 μm. The morphological and structural evolution of the products have been analyzed by controlling the hydrothermal temperature and reaction time. The Cu bismuthate nanosheets modified glassy carbon electrode (GCE) is used to investigate the electrochemical performance for the detection of tartaric acid in 0.1 M KCl electrolyte. A pair of semi-reversible CV peaks are located at −0.45 V and −0.02 V at the Cu bismuthate nanosheets modified GCE in 2 mM tartaric acid. The calculated detection limit is 1.6 μM at the signal to noise ratio of 3 with tartaric acid concentration of 0.005–2 mM. The nanosheets modified GCE shows good application promising for the electrochemical detection of biological molecules.

Graphene quantum dots (GQDs) and tartaric acid (TA) were successively electrodeposited onto the surface of a glassy carbon electrode (GCE). Due to the intrinsic chirality of L-(+)-TA and D-(−)-TA and the signal amplification function of GQDs, the GQDs–TA hybrid modified GCE could be regarded as an efficient electrochemical chiral sensing platform and used for chiral recognition of tryptophan (Trp) isomers. The recognition efficiency with the proposed GQDs–TA is significantly higher than that with TA alone. Of particular interest, GQDs-L-(+)–TA and GQDs-D-(−)–TA exhibit completely opposite selectivity toward L-Trp and D-Trp. Also in this work, the pH-sensitive enantiorecognition of the GQDs–TA hybrids was investigated.

Ni/SAPO-11 catalysts with highly dispersed Ni (TA-Ni/SA-11) were prepared using tartaric acid as a dispersant. The effect of the tartaric acid content on the physiochemical properties of the TA-Ni/SA-11 catalysts and their n-heptane hydroisomerization performance were investigated. TA-Ni/SA-11 exhibits smaller Ni particles and more Ni active sites in comparison to conventional Ni/SAPO-11 prepared via the impregnation method due to the interaction between tartaric acid and Ni 2+ . As the molar ratio of tartaric acid and Ni 2+ (n TA /n Ni ) increases, the number of Ni active sites in TA-Ni/SA-11 rises, while the surface area and relative crystallinity decrease because of the dealumination of SAPO-11. When n TA /n Ni is 0.75, 0.75TA-Ni/SA-11 presents the highest n-heptane conversion of 82.4% and isomer selectivity of 90.5%, as well as the lowest cracking selectivity of 9.0% at 380 °C, 1.5 MPa, 2 h − 1 , and a volume ratio of H 2 to n-heptane of 400 among these catalysts.

Non-traditional intrinsic luminescent polymers (NTILPs) have shown great potential in the fields of bioimaging and anti-counterfeiting applications. However, the intrinsic luminescent mechanism in these polymers is still under debate, with clustering-triggered emission (CTE) theory being one of the most plausible explanations, yet further research is needed. In this work, starting from acylamination of tartaric acid, we synthesized a pair of chiral polyamides, PA6LAT and PA6DAT. Circular dichroism spectroscopy confirmed the opposite helical conformations of PA6LAT and PA6DAT, exhibiting pronounced aggregation chirality amplification behavior and demonstrating typical CTE characteristics. The solid-state powders of the polyamides showed finely tunable multicolor fluorescence under different excitation wavelengths. The presence of through-space conjugations in the polyamides was further confirmed through theoretical calculations, revealing the significance of amide clusters and oxygen clusters in their CTE behavior. Interestingly, changing the solvent from HFIP to DMSO enabled single emission behavior in polyamide solutions, with the emission peak precisely tunable from 430 nm to 485 nm. This solvent-dependent shift is attributed to the differential dissociation of amide and oxygen clusters in these two solvents, corresponding to the opposite optical rotation of the polyamides induced by the solvents. The fluorescent behavior in solvents also further confirmed the emission mechanism triggered by amide and oxygen clusters in PA6LAT and PA6DAT. This study deepens the understanding of the intrinsic luminescent mechanism of polyamides, reporting for the first time the precise tuning of NTILPs fluorescence behavior and the underlying mechanism through solvent-induced effects, contributing to a better understanding of the multicolor luminescent behavior of NTILPs.

A novel tartaric acid co-precipitation process was firstly reported to prepare tetragonal BaTiO 3 nano-powder with barium chloride, titanium tetrachloride as raw materials and tartaric acid as precipitant agent. The as-obtained BaTiO 3 powder exhibited a small average particle size about 140 nm, which still held a high tetragonality (c/a ratio) of 1.0092, suggesting its promising applications in multilayer ceramic capacitors (MLCC). In addition, this synthetic method will be of general interest to people who focuses on synthesis technology of Ti-based multicomponent oxides nano-materials owing to its outstanding advantages, including mild reaction condition, facile synthetic processes and especially stabilization of (TiO) 2+ even in a high pH about 8.

The eco-benign water-absorbent gel was obtained by modification of tartaric acid (TA) onto parenchyma cellulose from corn stalk pith (CSP) in N, N-dimethylacetamide (DMAc)/LiCl system. The water affinity of the gel was aided with TA as both grafting agent and cross-linker via esterification. The degree of swelling was strongly influenced by TA amount, reaction temperature and duration, and the absorbency of TA-esterified product reached up to about 417 g H 2 O/g dry gel. The three-dimensional macro-porous structures of the bio-absorbent led to fast penetration and diffusion of water into gel. Studies of absorption behavior in deionized water showed that the initial water uptake followed the non-Fickian mechanism, the Schott second-order equation governed the swelling kinetics, and the later part of swelling was relaxation of polymer chains. FTIR and X-ray diffraction analyses confirmed successful modification of TA molecules onto cellulose chains through the formation of ester bonds and transition of crystalline forms from cellulose Ⅰ to cellulose Ⅱ. Moreover, thermogravimetric outcomes illustrated the thermal resistance of the TA-esterified gel with a loose structure was lower than SCP cellulose. This work designed a green water-absorbent that could be potentially utilized as favorable water retention material in agriculture and horticulture.

Tartaric acid (TA) is an important component of plant rhizosphere secretion, having a certain influence on the adsorption and desorption behavior of heavy metals in soil. Humin could serve as an environmentally compatible passivator of heavy metal in soil. The aims of this study were to simulate the adsorption of Pb (II) via humin in a soil solution, explore the effects of TA on the adsorption of Pb (II) by humin and elucidate the mechanism of its influence. The results indicated that the adsorption of Pb (II) on the surface of humin within and without TA was consistent with the Langmuir isotherm equation and the pseudo-secondary kinetic model (R 2 > 0.99). The effect of TA on adsorption was related to the concentration of TA. With the increasing of TA concentration, the adsorption of Pb (II) by humin showed a peak change and the adsorption amount reached the maximum with 0.5 mmol L −1 humin, is 192.31 mg L −1 with 0.1 mmol TA. Basing on adsorption experiments and characterization of FTIR, SEM, EDX and XPS. It revealed that the oxygenated groups of TA can be combined with humin by hydrogen bonding, in the low concentration TA (less than 0.5 mmol L −1 ), which is equivalent to an increment of the carboxyl group on the surface of humin, thus adsorption amount was increased. The increasing of the concentration of TA led to an increment of free TA in the solution, which would complex with the lead ions in the solution, and indirectly reduce the amount of Pb(II) adsorption on the humin.

Photoluminescent nano material has been reported as an intriguing field during the past few decades. In this article, tartaric-templated silica nanotubes were conveniently synthesized by sol–gel method. X-ray diffraction analysis, scanning electron microscopy, transmission electron microscopy, fourier transform infrared spectra and photoluminescence spectra analysis were employed to characterize the growth, structure, morphology and optical property of the products. It is found that tartaric templates can form spindle/spherical-like aggregates composed of many sheets under static/stirring condition, which lead to the different shapes of silica nanotubes. Then the probable strategies for silica nanotubes templating with tartaric acid were described particularly. Hydrogen-bond interaction, supramolecular interaction and a competition of various effects may be the reasons of the nanotubes formation. Moreover, under ultraviolet light excitation, the silica nanotubes exhibited blue emission and luminescent intensity of the tubes prepared under the static condition is much stronger than the stirring ones, mostly because of more defect centers in the structures obtained under stirring condition.

Single crystalline bismuth nickelate nanorods with cubic Bi 12 NiO 19 phase and flat tips have been successfully synthesized by a facile hydrothermal route without any additives. Electron microscopy observations show that the length and diameter of the bismuth nickelate nanorods are 1–3 μm μm and 30–100 nm, respectively. The formation, length and diameter of the nanorods depend on the hydrothermal temperature and duration time. The formation of the bismuth nickelate nanorods are explained according to the nucleation and crystalline growth process. The bismuth nickelate nanorods are applied as the glassy carbon electrode (GCE) materials for the detection of tartaric acid in KCl solution. The roles of scan rate, electrolyte species and tartaric acid concentration on the electrochemical responses of tartaric acid have been investigated. The obtained linear concentration calibration plot shows a low detection limit of 0.52 μm, wide linear range of 0.001–2 mM and correlation coefficient of 0.996. The bismuth nickelate nanorods modified GCE shows good reproducibility and stability.

With the rapid development of modern communication technology, the exploration of flexible wearable shielding fabrics with exceptional electromagnetic interference (EMI) shielding performance has emerged as an utmost priority to safeguard both human beings and electronic devices from the detrimental effects of electromagnetic radiation. Herein, a scalable multilayer stacking assembly method is proposed to prepare uniform MXene/CuNWs/Tartaric Acid (TA) composites-coated fabrics. MXene, as a new type of material, can achieve higher electron and ion transfer rates. However, it is prone to oxidation in air, leading to poor stability. Benefiting from the synergistic effect of tartaric acid, the MXene/CuNWs/TA-coated fabrics exhibit certain oxidation stability and corrosion resistance, while retaining the inherent flexibility and breathability of natural polymer textiles. Furthermore, the multilayer stacking structure works perfectly with the MXene/CuNWs conductive network, enabling multiple reflections and absorptions of electromagnetic waves internally, thus effectively diminishing energy transmission. The modified fabrics exhibit a low sheet resistance of 3.25 ± 0.12 Ω/sq and a good EMI shielding performance of 41.2 dB at X-band. Therefore, MXene/CuNWs/TA fabrics with high shielding performance are expected to reach their potential in wearable electronic products.
