And the article contained the following:

The rhizosphere is the narrow zone of soil immediately surrounding the root, and it is a critical hotspot of microbial activity, strongly influencing the physiol. and development of plants. For analyzing the relationship between the microbiome and metabolome in the rhizosphere of tea (Camellia sinensis) plants, the bacterial composition and its correlation to soil metabolites were investigated under three different fertilization treatments (unfertilized, urea, cow manure) in different growing seasons (spring, early and late summer). The bacterial phyla Proteobacteria, Bacteroidetes, Acidobacteria and Actinobacteria dominated the rhizosphere of tea plants regardless of the sampling time. These indicated that the compositional shift was associated with different fertilizer/manure treatments as well as the sampling time. However, the relative abundance of these enriched bacteria varied under the three different fertilizer regimes. Most of the enriched metabolic pathways stimulated by different fertilizer application were all related to sugars, amino acids fatty acids and alkaloids metabolism Organic acids and fatty acids were potential metabolites mediating the plant-bacteria interaction in the rhizosphere. Bacteria in the genera Proteiniphilum, Fermentimonas and Pseudomonas in spring, Saccharimonadales and Gaiellales in early summer, Acidobacteriales and Gaiellales in late summer regulated relative contents of organic and fatty acids. This study documents the profound changes to the rhizosphere microbiome and bacterially derived metabolites under different fertilizer regimes and provides a conceptual framework towards improving the performance of tea plantations. The experimental process involved the reaction of 2,3-Dihydroxypropanoic acid(cas: 473-81-4).Safety of 2,3-Dihydroxypropanoic acid

On June 15, 2022, Namdeo, Ashutosh; Jhaveri, Jainesh H.; Mahajani, S. M.; Suresh, A. K. published an article.COA of Formula: C3H6O4 The title of the article was Palladium catalyzed liquid phase oxidation of glycerol under alkaline conditions – Kinetic analysis and modelling. And the article contained the following:

Glycerol is a major byproduct of bio-diesel production and hence its utilization has been an area of high interest in the scientific community. Oxidizing glycerol to high-value products can improve the economics of bio-diesel production In the present work, we study glycerol oxidation in alk. medium using an activated carbon supported Palladium catalyst. Kinetic studies have been performed in a batch reactor to study the effect of different parameters such as NaOH concentration, temperature, and pressure. Our results point to product inhibition by adsorbing reactant and product species. We also observe a relative insensitivity of product yields at a given conversion, to the temperature Our observations further suggest that higher NaOH concentration gives better C3 selectivity while higher oxygen pressure results in lower C3 selectivity. Based on our own studies and the literature available, the most likely kinetic pathway and a kinetic model have been proposed. Our results suggest the possibility that C-C cleavage occurs directly from the primary intermediate aldehydic species, as a result of which, carbon chain scission products (including CO2) form from very early stages of the reaction. Various strategies such as pooling temperature data to estimate rate ratios prior to full parameter estimation, use of statistical significance tests to reduce model parameters etc have been used to arrive at a minimalistic model still capable of explaining all features of the oxidation Confidence bounds on the model parameters have been estimated The experimental process involved the reaction of 2,3-Dihydroxypropanoic acid(cas: 473-81-4).COA of Formula: C3H6O4

And the article contained the following:

Achieving efficient catalytic conversion over a heterogeneous catalyst with excellent resistance against leaching is still a grand challenge for sustainable chem. synthesis in aqueous solution Herein, we devised a single-atom Pt1/hydroxyapatite (HAP) catalyst via a simple hydrothermal strategy. Gratifyingly, this robust Pt1/HAP catalyst exhibits remarkable catalytic selectivity and catalyst stability for the selective oxidation of C2-C4 polyols to corresponding primary hydroxy acids. It is found that the Pt-(O-P) linkages with strong electron-withdrawing function of PO43- (Pt1-OPO43- pair active site) not only realize the activation of the C-H bond, but also destabilize the transition state from adsorbed hydroxy acids toward the C-C cleavage, resulting in the sharply increased selectivity of hydroxy acids. Moreover, the strong PO43–coordination effect provides electrostatic stabilization for single-atom Pt, ensuring the highly efficient catalysis of Pt1/HAP for over 160 h with superior leaching resistance. The experimental process involved the reaction of 2,3-Dihydroxypropanoic acid(cas: 473-81-4).Computed Properties of 473-81-4

In this work, different shaped WO3 (rod-like, lamellar and cuboid) supported Pt catalysts were prepared in a facile routine and tested in the selective oxidation of glycerol in base-free aqueous solution Characterizations indicated that rod-like WO3 supported Pt catalyst (Pt/R-WO3) possesses higher surface area because of the formation of vertical pore channels and highly exposed plane (100), the deposited Pt atoms combined strongly with the terminal -W=O in rod-like WO3. These properties promoted the adsorption, storage and surface diffusion of oxygen over Pt/R-WO3 which exhibited the excellent activity for the selective oxidation of glycerol. And the higher amount of acid sites on the surface of Pt/R-WO3 enhanced the selectivity of glyceric acid. The calculated turnover frequency of each Pt atom in Pt/R-WO3 reached 946 h-1 at 60°C. The experimental process involved the reaction of 2,3-Dihydroxypropanoic acid(cas: 473-81-4).Synthetic Route of 473-81-4

On May 20, 2022, Yang, Dan; Liu, Xuan; Song, Fei; Dai, Yihu; Wan, Xiaoyue; Zhou, Chunmei; Yang, Yanhui published an article.Name: 2,3-Dihydroxypropanoic acid The title of the article was Chemoselective Oxidation of Glycerol over Platinum-Based Catalysts: toward the Role of Oxide Promoter. And the article contained the following:

The metal oxide promoters remarkably enhance the catalytic activity of supported Pt catalysts in the glycerol oxidation toward glyceric acid, whereas the primary factor that metal oxide promotes the reaction, as well as the kinetics relevant step remain indistinct. Herein, manganese dioxide (MnO2) is chosen as a model to uncover the role of promoter in the glycerol oxidation over Pt-based catalyst in alkali-free solution The results prove that the superior catalytic performance is mainly attributed to the increased synergistic interaction between Pt particles and the metal oxides to boost the activation of oxygen (not glycerol), while the increased dispersion shows slight effect. Furthermore, the detailed kinetic studies reveal that MnO2 is prone to accelerate the awkward step of glyceraldehyde to glyceric acid, and the lattice oxygen of MnO2 also involves in this particular step.

And the article contained the following:

The exploration of potential application of glycerol is of particular importance for solving the oversupply of glycerol as an unavoidable byproduct of biodiesel and affording profitable possibilities for sustainable biodiesel. Herein, we developed a simple, cheap but robust Cu1Mg4 catalyst, which exhibited outstanding catalytic activity for the selective conversion of glycerol towards valuable glycolic acid, eliminating the addition of extra inorganic base. As high as 71.8% yield of glycolic acid was achieved, the highest value to date as far as we know. In combination of experiment and DFT calculations, it was revealed that Cu, Mg species in catalyst enabled the relay catalysis for the cascade reactions in glycerol transformation. Cu species in catalyst dominated the first dehydrogenation reaction of glycerol to glyceraldehyde, which was promoted by Mg species. Mg species followed to catalyze the next cleavage of C2-C3 bond in glyceraldehyde to generate glycolaldehyde. The final oxidation of glycolaldehyde to glycolic acid was achieved by the catalysis of Cu species. This relay catalysis of Cu1Mg4 catalyst significantly inhibited the formation of glyceric acid and lactic acid byproducts, thereby enabling the selective generation of glycolic acid. The experimental process involved the reaction of 2,3-Dihydroxypropanoic acid(cas: 473-81-4).Electric Literature of 473-81-4

W. published an article.Recommanded Product: 473-81-4 The title of the article was Biomass-derived polyols valorization towards glycolic acid production with high atom-economy. And the article contained the following:

Taking advantage of the inherent structure in biomass for attractive chem. synthesis with high atom economy is vital for a sustainable future but remains a great challenge. Herein, we discovered a new route for glycolic acid (GcA) synthesis using various biomass-derived polyols as feedstock with an exceptionally high atom utilization (~93%). Up to ~90 C-mol% yield of GcA could be achieved, representing the highest value among the state-of-the-art biomass valorization strategies. Strongly certified by in situ exptl. tests and multi-scale theor. calculations, it was identified that dynamical accommodation of the flexible unsaturated dangling-like Cucus-O bond in Cu2O(111) to polyols drove electron transfer from polyols to Cucus, enabling the precise activation of C1-H and C2-C3 bonds. These contributions accomplished the complex cascade reactions in polyol transformation throughout chain-sugar as intermediate with notable conformation superiority, thus generating GcA selectively.

On September 30, 2022, Xu, Shuguang; Tian, Qing; Xiao, Yuan; Zhang, Wenyu; Liao, Shengqi; Li, Jianmei; Hu, Changwei published an article.Computed Properties of 473-81-4 The title of the article was Regulating the competitive reaction pathway in glycerol conversion to lactic acid/glycolic acid selectively. And the article contained the following:

The numerous parallel reactions in glycerol conversion substantially challenge the effective synthesis of target chem. from oversupplied glycerol. Herein, we intensively studied the control of the complex reaction network in glycerol conversion, and realized the selective production of lactic acid or glycolic acid by integrating the use of different bases with Cu/γ-Al2O3 catalyst. The results indicated that base promoted the oxidation dehydrogenation of glycerol over Cu/γ-Al2O3 catalyst to glyceraldehyde intermediate. Remarkably, base significantly contributed to the control of the competitive reactions in the next glyceraldehyde transformation. DFT calculation revealed that strong base (NaOH) independently promoted the removal of H in C2 of glyceraldehyde, thereby facilitating the dehydration reaction and leading to the selective production of lactic acid. Combing with First-principles calculation, it was revealed that both NaHCO3 and CuO species contributed to increase the electrophilicity of C2 and C3 in glyceraldehyde, thereby directing the conversion of the resultant glyceraldehyde intermediate towards the cleavage of C2-C3 to glycolal. Cu/γ-Al2O3 then sep. catalyzed the oxidation of glycolal selectively to glycolic acid. This work might provide a promising approach and give some clues for the valorization of glycerol in widespread applications, thus affording profitable possibilities for the sustainable biodiesel.

On January 31, 2022, Vo, Truong-Giang; Ho, Po-Yun; Chiang, Chia-Ying published an article.Name: 2,3-Dihydroxypropanoic acid The title of the article was Operando mechanistic studies of selective oxidation of glycerol to dihydroxyacetone over amorphous cobalt oxide. And the article contained the following:

In this work, cobalt oxide (CoOx) has been demonstrated as an efficient and selective electrocatalyst for producing value-added dihydroxyacetone (DHA) from industrial byproduct glycerol. Under optimized conditions, DHA with high selectivity up to 45% and a high production rate of 9.6μmol h-1 cm-2 is obtained at high c.d. over 3 mA cm-2 without the occurrence of the oxygen evolution reaction. Operando Raman spectroscopy features the potential-induced structural transformation between CoOx and oxyhydroxides from which a correlation among applied potential, surface chem. of electrocatalyst, and product distribution are built. These results point toward the viability of using inexpensive materials for electrochem. biomass upgrading as well as providing opportunities for studying structural evolution and activity origin of catalysts under realistic working conditions that can be widely extended to most electrocatalytic biomass valorization processes.
