The pure water permeability of the neat PS membrane was 15 L.m−2 h−1 bar−1. The optimal dosage of the individually doped membranes was 1.5% weight CN to PS and 5% weight PEO to PS resulting in permeabilities of 56 and 237 L m−2 h−1 bar−1, respectively.

Although natural products are widely used as lead compounds for the design of therapeutic drugs, few studies have looked for potential wound healing compounds in nature. In this review, we briefly discuss each phase of the wound healing process. Examples of natural and non-natural products with wound healing activities are listed, and the ...

Environmentally friendly sulfonated black carbon (BC) catalysts were prepared from biodiesel waste, glycerol. These black carbons (BCs) contain a high amount of acidic groups, mainly sulfonated and oxygenated groups. Furthermore, these catalysts show a high catalytic activity in the glycerol etherification reaction with tert-butyl alcohol, the activity being larger for the sample prepared with a higher glycerol:sulfuric acid ratio (1:3). The yield for mono-tert-butyl glycerol (MTBG), di-tert-butyl glycerol ( ...

Abstract The influence of structural relaxation on crystal nucleation has been underexplored and remains elusive. This article discusses its possible effect on the nucleation process using a stoichiometric soda‐lime‐silica (2Na 2 O·CaO·3SiO 2 ) glass as a model system. We show that the relaxation effect is powerful at low temperatures, close and below the glass transition, , and leads to a continuous increase in the nucleation rate. At any given temperature, the nucleation rate eventually reaches its ...

In this work, we significantly extend our new approach for analyzing nucleation kinetics below the glass transition, Tg, which considers the structural relaxation effect. Using a 5BaO·8SiO2 (B5S8) glass, we showed a significant stepwise change in the nucleation relaxation time, τsr, with temperature in the Tg region, in contrast with the expected monotonous variation with temperature: τsr is four times shorter for the supercooled liquid than for the glass. Then, using a combination of new experimental ...

Nucleation is one of the primary contributions to the microstructure of glass-ceramics. However, the nucleation process within glass-ceramics is not understood across all glass systems, nor is the specific role of nucleating agents. The present article proposes a comprehensive definition of a nucleating agent: "a nucleating agent is a minority component of the glass composition that leads to increased internal nucleation rates or precipitation and control of desired crystal phases, either by lowering ...

Fungi are some of the most neglected pathogens in terms of new drug discovery. Paracoccidioidomycosis, an endemic disease to South America, is caused by dimorphic fungi of Paracoccidioides genus. Reasonable citotoxicity, limited efficacy, and frequent use of current commercial antifungals have led to the emergence of resistance. Thus, the development of new antifungals with more selectivity and large spectrum of action is mandatory. In this work, six calix[n]arenes were synthesized and their activity ...

Abstract We collected a plethora of new data to test the hypothesis that the failure of the Classical Nucleation Theory (CNT) below the glass transition range is just an experimental artifact. Since reaching the steady‐state nucleation regime takes a significant time for treatments below the glass transition temperature, data collected in this temperature range tend not to have reached a steady state. Because of this potential problem, we examined the CNT using new experimental data for three stoichiometric ...
