We propose an apparatus for teaching experimental thermodynamics in undergraduate introductory courses, using thermoelectric modules and a real-time data acquisition system. The device may be made at low cost, still providing an easy approach to the

We have created laboratory conditions similar to those present in a lake when the external temperature falls below 0°C. Glaciation in lakes is described in school textbooks and classroom demonstrations.1,2 It is pointed out how the anomalous behavio

Photocatalysis on titanium dioxide is dependent on the presence of suitable electron donors and acceptors in the system. In this paper, we tested Pyrococcus furiosus , Acetomicrobium flavidum and Clostridium pasteurianum hydrogenase as electron accep

We report experimental evidence of transition scenarios during the chemical evolution in an unstirred closed Belousov−Zhabotinsky (BZ) system. We demonstrate that during its chemical evolution the system spontaneously gives the following sequence o

Nitric oxide (NO) is known as a multifaceted bioregulatory agent and an environmental pollutant. We investigated the role of nitric oxide in phospholipid solutions by NMR techniques. A mixture of lipids dissolved in a ternary solvent was used. 31P NM

Nitric oxide is implicated in a wide range of biological functions and in many processes of ecological importance. The formation of iron–nitrosyl complexes is fairly well documented, although the oxidation state of the iron atom is not adequately e

We have shown that in the presence of a reactive substrate, chlorinated organic compounds can be dehalogenated by mechanical treatment, and a specific reaction product can be obtained. We have used a ball milling process at low temperature and atmosp

Aperiodic oscillations in a cerium catalyzed Belousov-Zhabotinsky reaction were experimentally observed in a closed system. This phenomenon was noted by a simple spectrophotometric measure which enabled us to prove the dependence of the initial condi

Monoanionic complexes of chromium(III) like [Cr(sq)2(cat)]−, where the ligands are anionic radicals such as 1,2-semiquinones and catecholates unsubstituted and 3,5-di-tert-butyl-substituted were detected after interaction of chromate anion (Cr(VI),

We analyzed the changes in the shape and resonance positions of the 31P NMR signals of phospholipid mixtures in a single-phase solvent containing different quantities of chloroform, methanol, and water. We obtained extremely reproducible NMR signals
