Inorganic gels as precursors of TiO2 photocatalysts prepared by low temperature microwave or thermal treatment
2008
Abstract A simple procedure for preparing active TiO2 photocatalysts is presented. The starting materials were unusual TiO2 gels formed from TiCl4. The use of microwaves for a very short time enhanced the TiO2 crystallinity preventing an increase of particle size and minimizing the decrease of specific surface area. This result makes this preparation very attractive. The formation of the gels was monitored through measurements of viscosity. All the samples were characterized by means of X-ray diffraction, diffuse reflectance spectroscopy and BET specific surface area measurements. The photoactivity of the samples was evaluated using the photodegradation of 4-nitrophenol in liquid–solid regi…
Frontiers of metal-coordinating drug design
2020
INTRODUCTION: The occurrence of metal ions in biomolecules is required to exert vital cellular functions. Metal-containing biomolecules can be modulated by small-molecule inhibitors targeting their metal-moiety. As well, the discovery of cisplatin ushered the rational discovery of metal-containing-drugs. The use of both drug types exploiting metal–ligand interactions is well established to treat distinct pathologies. Therefore, characterizing and leveraging metal-coordinating drugs is a pivotal, yet challenging, part of medicinal chemistry. AREA COVERED: Atomic-level simulations are increasingly employed to overcome the challenges met by traditional drug-discovery approaches and to compleme…
Adverse drug reactions in some African herbal medicine: literature review and stakeholders’ interview
2014
International audience; Background: In view of the large consumption of herbal medicine in Africa countries, it is likely that many adverse drugs reactions go unrecorded with either patients failing to present to health services, or no pharmacovigilance analysis being made, or the analysis not being reported centrally. This problem is of interest especially for those who are working in the general area of adverse drug reactions or stakeholders in the domain of herbal medicine for considering safety issues. Methods: We are particularly interested in the way that the use of very wellknown and highly valued plants is linked to the observation of adverse drug reactions in African countries. We …
Dental Public Health Landscape: Challenges, Technological Innovation and Opportunities in the 21st Century and COVID-19 Pandemic
2020
The convergent forces of rising costs, growing consumerism, expensive new treatments, sociodemographic shifts and increasing health disparities are exerting intense and unsustainable pressures on healthcare systems. As with the other health domains, these disruptive forces demand new approaches and delivery models for oral healthcare. Technological innovations and practices borrowed from the e-commerce and tech sectors could facilitate the move to a sustainable 21(st) century oral healthcare system, one that delivers high-quality, value-based care to wider groups of patients. The broad reach of mobile technologies and changing digital lifestyles provide unique opportunities for using remote…
Electrochemical abatement of chloroethanes in water: Reduction, oxidation and combined processes
2010
An electrochemical route, based on the anodic oxidation to carbon dioxide coupled with the cathodic reduction to de-halogenated hydrocarbons, was proposed for the treatment of waters contaminated by chloroethanes. The electrochemical abatement of two model compounds, namely 1,2-dichloroethane and 1,1,2,2-tetrachloroethane, was carried out by cathodic reduction at silver, anodic oxidation at boron doped diamond (BDD) and combined processes. The anodic oxidation gives rise to a high abatement of the concentration of both these compounds and of COD. The reduction of 1,1,2,2-tetrachloroethane proceeds also with high abatement but with the formation of some halogenated intermediates and final pr…
Making white spots disappear! Do minimally invasive treatments improve incisor opacities in children with molar-incisor hypomineralisation?
2022
BACKGROUND Children with molar incisor hypomineralisation (MIH) frequently seek aesthetic treatment for incisor opacities. Surprisingly few studies have evaluated the clinical success of such interventions. AIM To quantify the effectiveness of minimally invasive treatments in reducing enamel opacity visibility in children with MIH. DESIGN This in-vitro study used digital clinical images of 23 children aged 8-16 years with MIH who underwent microabrasion and/or resin infiltration for management of incisor opacities. Standard images were taken pre- and six-months post-treatment. Image software (Image-Pro Plus®V7) was employed to convert 24-bit RGB images to 16-bit grey-scale and 45% magnifica…
Modeling temporal treatment effects with zero inflated semi-parametric regression models: The case of local development policies in France
2017
International audience; A semi-parametric approach is proposed to estimate the variation along time of the effects of two distinct public policies that were devoted to boost rural development in France over a similar period of time. At a micro data level, it is often observed that the dependent variable, such as local employment, does not vary along time, so that we face a kind of zero inflated phenomenon that cannot be dealt with a continuous response model. We introduce a conditional mixture model which combines a mass at zero and a continuous response. The suggested zero inflated semi-parametric statistical approach relies on the flexibility and modularity of additive models with the abi…
Effectiveness of sodium acetate treatment on the mechanical properties and morphology of natural fiber-reinforced composites
2021
This paper aims to investigate the ability of an eco-friendly and cheap treatment based on sodium acetate solutions to improve the mechanical properties of flax fiber-reinforced composites. Flax fibers were treated for 5 days (i.e., 120 h) at 25 °C with mildly alkaline solutions at 5%, 10% and 20% weight content of the sodium salt. Quasi-static tensile and flexural tests, Charpy impact tests and dynamical mechanical thermal (DMTA) tests were carried out to evaluate the mechanical properties of the resulting composites. Fourier transform infrared analysis (FTIR) was used to evaluate the chemical modification on the fibers surface due to the proposed treatment, whereas scanning electron micro…
Effect of Hot Air Treatment on Quality and Shelf Life of Minimally Processed Cauliflower.
2012
Cauliflower, as other cabbages, has a high nutritional value due to its content of vitamins, antioxidants and anti-carcinogenic compounds. Cauliflower inflorescences are harvested when they are still totally immature. The request of minimally processed vegetable is continuously increasing, and there is a growing interest for new fresh cut products. Cauliflower is suitable to be used as a minimally processed vegetable, but harvesting and the following processing can cause a severe stress determining the appearance of accelerated senescence symptoms. The effect of hot air treatment on minimally processed cauliflower was investigated. Florets were put in PE sealed bags before treating at 48°C …
