Production of Poly(3-hydroxybutyrate--3-hydroxyvalerate) (PHBV) by Using Candy Industry Waste as Raw Materials.

The haloarchaeon synthesizes poly(3-hydroxybutyrate--3-hydroxyvalerate) (PHBV) under unfavorable nutritional conditions without the addition of any precursor to the culture, which is an advantage compared to other microbial counterparts able to synthesize polyhydroxyalkanoates (PHA). PHBV is a biodegradable polymer showing physiochemical properties of biotechnological and biomedical interest and can be used as an alternative to plastics made from chemical synthesis (which are not environmentally friendly). The versatile metabolism of makes the use of waste as a carbon source for cellular growth and PHA synthesis possible.

A Vibration-Induced-Emission-Based Fluorescent Chemosensor for the Selective and Visual Recognition of Glucose.

The development of chemosensors to detect analytes in biologically relevant solutions is a challenging task. We report the synthesis of a fluorescent receptor that combines vibration-induced emission (VIE) and dynamic covalent chemistry for the detection of glucose in aqueous media. We show that the bis-2-(N-methylaminomethyl)phenylboronic acid-decorated N,N'-diphenyl-dihydrodibenzo[a,c]phenazine (DPAC) receptor 1 can detect glucose and discriminate between closely related monosaccharides including those commonly found in blood.

Modulation of the Selectivity in Anions Recognition Processes by Combining Hydrogen- and Halogen-Bonding Interactions.

Most of the halogen bonding receptors for anions described use halogen bonding binding sites solely in the anion recognition process; only a few examples report the study of anion receptors in which the halogen bonding interaction has been used in combination with any other non-covalent interaction. With the aims to extend the knowledge in the behaviour of this kind of mixed receptors, we report here the synthesis and the anion recognition and sensing properties of a new halogen- and hydrogen- bonding receptor which binds anions by the cooperation of both non-covalent interactions. Fluorescence studies showed that the behaviour observed in the anion recognition sensing is similar to the one previously described for the halogen analogue and is quite different to the hydrogen one.

Synthesis and crystal structure of [Pd{CH(CHNHCHPh)-2-κ,}(μ-I)].

The binuclear title complex, di-μ-iodido-bis(-{2-[(benzylamino-κ)meth-yl]phenyl-κ}palladium(II)), [PdI(CHN)], was prepared by reaction of [Pd{CH(CHNHCHPh)-2}(μ-OAc)] with NaI. It crystallizes with one discrete mol-ecule in the asymmetric unit. The mol-ecule presents an iodide-bridged dimeric structure with a arrangement with respect to the ,-cyclo-palladated ligands.
