Organometallic capsule with unusual charge-transfer interactions
This study will pave the way for organometallic capsules withcatalytic, magnetic, and medicinal properties. Credit: Tokyo Tech Ferrocene is an emergent organic-metal hybrid compound, and its accidental discovery has led to the rapid development of organometallic chemistry. Aside from its interesting structure, which consists of an iron atom sandwiched between two pentagonal organic rings, ferrocene…

One-pot synthesis of iron–sulfur proteins under aerobic conditions
The proposed approach allows for the one-pot production of oxygen sensitive metalloproteins without relying on cell cultures and the glovebox, making it convenient in terms of time and handling. Credit: ELSI S clusters, which are a part of Fe–S proteins, are found across all forms of life. They play a significant role as biological cofactors—helper…

US safety board warns of hurricane threat to chemical facilities | News
The chairman of the US Chemical Safety Board (CSB) has warned that hurricanes and high winds could ‘significantly impact’ the US bulk-power system and trigger the release of hazardous chemicals if facilities lose power. In a letter to the US Federal Energy Regulatory Commission (FERC) last month, CSB chair Steve Owens urges FERC’s acting chairman…

The key compounds responsible for sourdough’s flavour | Research
10 key taste compounds and 11 aroma compounds are responsible for the unique flavour of sourdough bread. Researchers from the Technical University of Munich, Germany, who made the findings, say that this knowledge could help bakers to control the quality of their breads and make their products more consistent. The work was presented at the autumn…

Development of innovative methodology for determination of 6-thioguanine in whole blood erythrocytes by HPLC–PDA-based technique for medical diagnostics purposes
The HPLC method was developed for the determination of 6-thioguanine (6-TG) in whole blood samples containing red blood cells (RBCs) using 5-bromouracil (5-BU) as internal standard (IS) was developed. A mobile phase consisting of ACN/buffer KH2PO4 (3/97, v/v) with 50 µl H3PO4 in isocratic flow was used. 6-TG was detected at wavelength 341 nm and 6-BU at…

Osteogenic induction of asiatic acid derivatives in human periodontal ligament stem cells
Materials The derivatives of AA, 501, 502, 503, and 506 were synthesised and derivatised from AA and Asiaticoside. The chemical structures of AA and its derivatives, and the 1H-NMR, are presented in Fig. 1 and Supplementary data, Figures S1–S4. All chemicals were of analytical grade and purchased from Sigma-Aldrich (Burlington, MA, USA) or Thermo Fisher Scientific…

Synthesis and characterization of Ce0.5Bi0.5VO4/rGO nanocomposite by sonochemical method for photocatalytic desulfurization of petroleum derivatives
XRD studies and mechanism of Ce0.5Bi0.5VO4/rGO formation X-ray diffraction patterns of samples S1, S2, and S3, which belong to CeVO4, BiVO4, and CeVO4/BiVO4, respectively, are shown in Fig. 2a–c. As can be seen, the samples are amorphous, which is due to the use of ultrasound waves for synthesis. Figure 2d corresponds to sample S3 (CeVO4/BiVO4) after calcination…
