This review on the RM1 model presents improvements to the methodology as well as a wide range of its applications to theoretical, organic, physical, analytical, and inorganic chemistry, along with their interfaces with medicine, biology, and materials science.

Natural deep eutectic solvents (NADES) comprise a new family of agro-based, eco-friendly reaction media that can replace traditional organic solvents in polymerization and polymer reactions. A review of the current progress in this exciting new field is given in this article.

New α-Bi₂O₃@PPy core-shell hybrid composite based on polypyrrole (PPy) electropolymerized with ordered α-Bi₂O₃, which intensified the electrochemical properties, making it promising for supercapacitor application.

Human hair was used as an efficient adsorbent for palladium(II) in solution and, after a mild thermal treatment, well-dispersed Pd nanoparticles were obtained.

The non-hydrolytic sol-gel route is a single methodology to obtain different host for applications as light emission. The ruby and other semi-precious stones can be obtained by sol-gel methodology. The luminescence spectra indicated the octahedral symmetry of the chromium(III) ion replacing aluminum(III) ion in the alumina matrix.

The intensity of pyrene fluorescence bands increases with increasing sodium dodecyl sulfate (SDS) concentration, overriding the suppressive effect of peroxotungstic acid (PTA). The image at left shows small angle X-ray scattering curve for PTA/NaCl/SDS/ethanol/water and the resulting fractal structured films.

Dispersive solid phase extraction combined with headspace sampling was introduced and applied to separation and pre-concentration of polycyclic aromatic hydrocarbons (PAHs).

A biocatalytic cascade process was developed using the yeast Candida albicans CCT 0776 and a commercially available ketoreductase to promote deracemization of (±)-1-arylethanols, in high substrate concentration (above 100 mmol L^-1), to prepare the (R)-alcohols (90-99%), with a high enantiomeric excess (83-99%) after 2-19 h.

Study of the use of Fourier transform infrared spectroscopy combined with multivariate analysis to identify adulterations in raw milk and in samples from producers.

Before and after fine particulate matter on filter samples inside a bus station.

The new friedelan-1,3,21-trione, nine known friedelanes, gutta-percha, squalene and a mixture of long-chain fatty acids were reported for the first time from Tontelea micrantha and also its genus. Its extracts inhibited Zika virus (ZIKV) multiplication at different stages, presenting a high virucidal effect.

Ablation process by laser-induced breakdown spectroscopy (LIBS) on dietary supplement surface and multi-energy calibration method (MEC).

Irradiation of a HAuCl₄ solution with the 532-nm emission of a pulsated Nd-YAG laser results in the production of pristine gold nanoparticles.

Design of experiments was successfully applied to optimize atmospheric pressure photoionization (APPI)(±) Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) parameters for crude oil and its saturate, aromatic, resin and asphaltene (SARA) fractions analyses.

The combination of nuclear magnetic resonance (NMR) and mass spectrometry (MS) to directly analyze crude extracts of Bertholletia excelsa bark residues indicated this biomass as a source of health-promoting compounds. Therefore, a potential raw material for food, pharmaceutical and chemical industries is described herein.

This work showed that apparent herb-drug pharmacokinetic interaction existed between aspirin and dengzhanxixin injection, and the combination of aspirin and dengzhanxixin injection noticeably altered the absorption, distribution and disposition of salicylic acid.

This work explores the synthesis and characterization of seven new composites based on lanthanide-succinates coordination polymers and activated carbon.

A comparative study of the dehydration of glycerol with alcohols over ion exchange resin Amberlyst-35 was performed. The effect of catalyst amounts, reaction temperature, time, and the molar ratio of alcohols to glycerol were also studied.

Top figure shows the H₂O₂-stimulated colorimetric assay for monitoring of glucose oxidase (GOx) activity and the bottom figure displays the mimic enzyme-chromogenic substrate-based colorimetric immunoassay (MECI) by coupling with the hemin/4-aminoatipyrine/phenol system.

A novel and sensitive flow-injection chemiluminescence (FI-CL) method was developed for the detection of norfloxacin (NFLX) and ofloxacin (OFLX) in commercial drug, milk and human urine samples based on Ag^III-ruthenium(II) bipyridine in acidic solution.

A novel method for selective extraction of cadmium ions in water samples was performed using ion-imprinted polymer. Box-Behnken design was used in the optimization of the principal variables of pre-concentration.

Glycerol proved to be efficient towards the synthesis of well crystalline zinc ferrite nanoparticles, with highlighted characteristics.
