Highlights•Citrus peel and fruit juices waste streams are rich in limonene molecule.•Limonene can be used in the nutritional, pharmaceutical and cosmetic fields.•Traditional techniques to recover limonene involve the use of polluting solvents.•Cost-benefit analysis is required to estimate the most viable extracting technique.•Anaerobic digestion and fermentation are suitable post-limonene extraction processes. AbstractThe citrus peels and residue of fruit juices production are rich in D-limonene, a cyclic terpen characterized by antimicrobial activity, which could hamper energy valorization bioprocess. Considering that limonene is used in nutritional, pharmaceutical and cosmetic fields, citrus by-products processing appear to be a suitable feedstock either for high value product recovery or energy bio-processes. This waste stream, more than 10 MTon at 2013 in European Union (AIJN, 2014), can be considered very interesting, from the view point of conducting a key study on limonene recovery, as its content of about 1% w/w of high value-added molecule. Different processes are currently being studied to recover or remove limonene from citrus peel to both prevent pollution and resources and energy recovery. The present review is aimed to highlight pros and contras of different approaches suggesting an energy sustainability criterion to select the most effective one for materials and energy valorization.

•Multistep procedure for process energy sustainability is proposed.•All the energy terms were considered direct as well as the indirect by LCA approach.•Fuzzy modelling has been used to score different process using EROI and EPT values.•The Anaerobic Digestion using organic wastes and maize as feed has been analyzed.•Results shown that the use of organic wastes is two folds more sustainable than maize. AbstractThe present paper proposes a fuzzy procedure for evaluating and scoring the energy sustainability of a process. The fuzzy procedure permits to handle Energy Return on Investment (EROI) and Energy Payback Time (EPT) values as characterizing parameters for the energy sustainability evaluation. The procedure is articulated in three steps: a first screening among many processes is performed by using the Energy Sustainability Index (ESI), which takes into account the total Produced Energy referred respect to the direct spent energy (heat and electricity). The second step is the Analogical Model, i.e. the quantification of each chemicals, materials and energy to estimate the Useful Energy with a Life Cycle approach, taking into account all the Indirect Energy terms. The third step is the evaluation of two parameters: EROI and EPT, considering all the involved energy flows. Therefore, a fuzzy combination of EROI and EPT permits to evaluate a Sustainable Useful Index (SUI). This procedure is useful for local planning, for allocating financing resources for new energy processes exploitation and for selecting the most sustainable choice among several research programs. Here two cases-studies are reported and compared to highlight the approach: the Anaerobic Digestion producing CH4 using Organic Refuses and maize as Energy Crop.

Highlights•Carbon felt is modified using HNO3 activation and original polyaniline layer deposition methods.•Both modification methods increase roughness and bacteria attachment on carbon felt.•Modified carbon felts decrease activation losses by promoting electron transfer.•Power losses are avoided by strong reduction of resistivity of modified electrodes.•MFC performances are increased up to three times using modified carbon felts. AbstractCommercial carbon felt is frequently used as anodic material in MFCs (Microbial Fuel Cells). In this work, it is modified through nitric acid activation and polyaniline deposition with the aim of improving power density. The modified anodic materials are characterized from both morphological and chemical point of views by FESEM (Field Emission Scanning Electron Microscope), EDS (Energy Dispersive Spectroscopy), FT-IR (Fourier Transform Infrared Spectroscopy), resistivity measurements and impedance spectroscopy. In addition, their performances are evaluated by comparing them with commercial carbon felt as anode material in a two-compartment laboratory MFC prototype using Saccaromyces cerevisiae as active microorganism in the anodic chamber. The electrochemical measurements are performed by means of LSV (Linear Sweep Voltammetry) and CI (Current Interrupt) techniques. The power density of the HNO3-treated and the polyaniline-covered carbon felts results 2.5 and 2.9 fold higher than commercial carbon felt, respectively. The increase of the power density obtained by both surface treatments seems to be related with a strong reduction of resistivity of the anodic material. Graphical abstract

During rest, brain activity is synchronized between different regions widely distributed throughout the brain, forming functional networks. However, the molecular mechanisms supporting functional connectivity remain undefined. We show that functional brain networks defined with resting-state functional magnetic resonance imaging can be recapitulated by using measures of correlated gene expression in a post mortem brain tissue data set. The set of 136 genes we identify is significantly enriched for ion channels. Polymorphisms in this set of genes significantly affect resting-state functional connectivity in a large sample of healthy adolescents. Expression levels of these genes are also significantly associated with axonal connectivity in the mouse. The results provide convergent, multimodal evidence that resting-state functional networks correlate with the orchestrated activity of dozens of genes linked to ion channel activity and synaptic function.
