Pemanfaatan Ekstrak Biji Feun Kase (Thevetia peruviana) sebagai Inhibitor Korosi Logam Seng dalam Media HCl
Authors: Batu Matius Stefanus , Kolo Maria Magdalena , Kono Adolvina
Published: October 2022

Feun Kase seed extract can be used as a corrosion inhibitor on zinc metal in HCl solution. This study aims to determine the secondary metabolites contained in Feun Kase seed extract, inhibition efficiency and corrosion rate, and surface morphology of zinc metal in the inhibition process using Feun Kase seed extract in HCl media. Feun Kase seed extract was obtained by maceration extraction using methanol. In the corrosion inhibition test, the concentration and temperature variations were carried out to determine the effect on the inhibition efficiency and the corrosion rate per year. The results showed that the methanol extract of Feun Kase seeds contained secondary metabolites of alkaloids, flavonoids and saponins. The optimum inhibition efficiency was obtained at an inhibitor concentration of 30 ppm of 82.70% with a corrosion rate of 5.80 mm/year and at a temperature of 35ºC of 75.84% with a corrosion rate of 7.28 mm/year in the test of increasing the temperature of the corrosion medium. The morphological analysis of the zinc plate using the SEM instrument showed that the zinc plate without surface treatment (not immersed in HCl media) was still smooth. This is indicated by the surface of the zinc plate which is still clearly visible because it has not been affected by the corrosion medium. The zinc plate when immersed in HCl media, is damaged which is indicated by the presence of pores or holes. Zinc plate when added with Feun Kase seed extract in HCl media, the zinc surface was damaged but the damage was not as prominent as in HCl media without using an inhibitor.

Highly non-stoichiometric YAG ceramics with modified luminescence properties

Published: October 2022

Yttrium aluminium garnet Y3Al5O12 (YAG) is a widely used phosphor host. Its optical properties are tuned by chemical substitution at its YO8 or AlO6/AlO4 sublattices, with emission wavelengths defined by a finite number of rare-earth (YO8 sublattice) and transition-metal (AlO6/AlO4 sublattice) dopants which have been explored extensively. Non-stoichiometric compositions Y3+xAl5-xO12 (x ≠ 0) may offer a route to new emission wavelengths by distributing dopants over multiple crystallographic sites, but deviation from Y3Al5O12 stoichiometry is difficult to achieve and limited generally to < 1% excess Y3+. Here we report a series of highly non-stoichiometric YAG ceramics Y3+xAl5-xO12 (0 ≤ x ≤ 0.4), with up to 20% of the AlO6 sublattice substituted by Y3+, synthesised by advanced melt-quenching techniques. This impacts the up-conversion luminescence of Yb3+/Er3+-doped systems, whose yellow-green emission contrasts with the red-orange emission of their stoichiometric counterparts. This contrasts with YAG:Ce3+ where the dopant ions occupy the YO8 sublattice exclusively, with down-conversion luminescence that is hardly affected by host nonstoichiometry. Beyond YAG, analogous highly non-stoichiometric systems should be obtainable for a range of functional garnets, demonstrated here by the successful synthesis of Gd3.2Al4.8O12 and Gd3.2Ga4.8O12. This opens the way to property tuning by control of garnet host stoichiometry, and the prospect of improved performance or new applications for garnet-type optical and magnetic materials.
Alkyl Formates as Transfer Hydroalkylation Reagents and Their Use in the Conversion of Imines to Alkylamines
Authors: Crochet Etienne , Anthore-Dalion Lucile , Cantat Thibault
Published: October 2022

Easily accessible via a simple esterification of alcohols with formic acid, alkyl formates are used as a novel class of transfer hydroalkylation reagents, CO2 acting as a traceless linker. As a proof-of-concept, their reactivity in the transfer hydroalkylation of imines is investigated, using a ruthenium-based catalyst and LiI as promoter to cleave the C−O σ–bond of the formate scaffold. Providing tertiary amines, the reaction displays a reverse and complementary regioselectivity compared to previously reported transfer hydroalkylation strategies.
Allosteric rescue of catalytically impaired ATP phosphoribosyltransferase variants links protein dynamics to active-site electrostatic preorganisation

Published: October 2022

ATP phosphoribosyltransferase catalyses the first step of histidine biosynthesis and is controlled via a complex allosteric mechanism where the regulatory protein HisZ enhances catalysis by the catalytic protein HisGS while mediating allosteric inhibition by histidine. Activation by HisZ was proposed to position HisGS Arg56 to stabilise departure of the pyrophosphate leaving group. Here we report active-site mutants of HisGS with impaired reaction chemistry which can be allosterically restored by HisZ despite the HisZ:HisGS interface lying ~20 Å away from the active site. MD simulations indicate HisZ binding constrains the dynamics of HisGS to favour a preorganised active site where both Arg56 and Arg32 are poised to stabilise leaving-group departure in WT-HisGS. In the Arg56Ala-HisGS mutant, HisZ modulates Arg32 dynamics so that it can partially compensate for the absence of Arg56. These results illustrate how remote protein-protein interactions translate into catalytic resilience by restoring damaged electrostatic preorganisation at the active site.
Exploring Deep Learning for Metalloporphyrins: Databases, Molecular Representations, and Model Architectures
Authors: Su An , Zhang Chengwei , She Yuanbin , Yang Yun-Fang
Published: October 2022

Metalloporphyrins have been studied as biomimetic catalysts for more than 120 years and have accumulated a large amount of data, which provides a solid foundation for deep learning to discover chemical trends and structure-function relationships. In this study, key components of deep learning of metalloporphyrins, including databases, molecular representations, and model architectures, were systematically investigated. A protocol to construct canonical SMILES for metalloporphyrins was proposed, which was then used to represent the two-dimensional structures of over 10,000 metalloporphyrins in an existing computational database. Subsequently, several state-of-the-art chemical deep learning models, including graph neural network-based models and natural language processing-based models, were employed to predict the energy gaps of metalloporphyrins. Two models showed satisfactory predictive performance (R2>0.94) with canonical SMILES as the only source of structural information. In addition, an unsupervised visualization algorithm was used to interpret the molecular features learned by the deep learning models.
