Zeolites have been little investigated for food applications,despite their chemical composition is similar to clays and clay minerals,which have been extensively analyzed for various applications,including food.Zeolites can be distinguished from clay materials,since the former have a porous microstructure characterized by intracrystalline cavities and channels,while the latter have a laminar microstructure.The goal of this review paper was to give a comprehensive perspective in terms of the different food applications found so far for zeolites,namely:antimicrobial materials,ethylene scavengers,fillers for food packaging materials,food nanoreactors,food substance sensors,immobilizers and stabilizers of active compounds and enzymes,molecular sieves for the pretreatment of food samples,as well as intelligent food contact materials.The main food applications from zeolites are related to their good properties as adsorbent materials,and these properties can be altered and tuned by ion exchange,surface organo-modification,among others,for a specific designed application.Zeolites for food applications have been investigated primarily as antimicrobial materials,concentrators of target analytes and sensors for food substances.However,the other potential food applications indicated above from zeolites are booming,since they are harmless materials recognized by various organizations.

AIM: To evaluate the effect of an extract of Geranium schiedeanum(Gs) as a hepatoprotective agent against ethanol(Et OH)-induced toxicity in rats. METHODS: Male Wistar rats weighing 200-230 g were subjected to a 70% partial hepatectomy(PH); they were then divided into three groups(groups 1-3). During the experiment, animals in group 1 drank only water. The other two groups(2-3) drank an aqueous solution of Et OH(40%, v/v). Additionally, rats in group 3 received a Gs extract daily at a dose of 300 mg/kg body weight intragastically. Subsequently, to identify markers of liver damage in serum, alanine aminotransferase, aspartate aminotransferase, albumin and bilirubin were measured by colorimetric methods. Glucose, triglyceride and cholesterol concentrations were also determined. In addition, oxidative damage was estimated by measuring lipid peroxidation [using thiobarbituric-acid reactive substances(TBARS)] in both plasma and the liver and by measuring the total concentration of antioxidants in serum and the total antioxidant capacity in the liver. In addition, a liver mass gain assessment, total DNA analysis and a morpho-histological analysis of the liver from animals in all three groups were performed and compared. Finally, the number of deaths observed in the three groups was analyzed.RESULTS: Administration of the Geranium shiedeanum extract significantly reduced the unfavorable effect of ethanol on liver regeneration(restitution liver mass: PHEt OH group 60.68% vs PH-Gs-Et OH group 69.22%). This finding was congruent with the reduced levels of hepatic enzymes and the sustained or increased levels of albumin and decreased bilirubin in serum. The extract also modified the metabolic processes that regulate glucose and lipid levels, as observed from the serum measurements. Lower antioxidant levels and the liver damage induced by Et OH administration appeared to be mitigated by the extract, as observed from the TBARs(PH-Et OH group 200.14 mmol/mg vs PH-Gs-Et OH group 54.20 mmol/mg; P < 0.05), total status of antioxi

Sodium-ion batteries(SIBs)are considered as a promising candidate to replace lithium-ion batteries(LIBs)in large-scale energy storage applications.Abundant sodium resources and similar working principles make this technology attractive to be implemented in the near future.However,the development of high-performance carbon anodes is a focal point to the upcoming success of SIBs in terms of power density,cycling stability,and lifespan.Fundamental knowledge in electrochemical and physicochemical techniques is required to properly evaluate the anode performance and move it in the right direction.This review aims at providing a comprehensive guideline to help researchers from different backgrounds(e.g.,nanomaterials and thermochemistry)to delve into this topic.The main components,lab configurations,procedures,and working principles of SIBs are summarized.Moreover,a detailed description of the most used electrochemical and physicochemical techniques to characterize electrochemically active materials is provided.

We have shown that the expression =2tan-1/ derived by Ranganathan to calculate the angles at which there exists a CSL for rotational interfaces in the cubic system can also be applied to general (oblique) two-dimensional lattices provided that the quantities 2 and /cos() are rational numbers, with =|b|/|a| and is the angle between the basis vectors a and b. In contrast with Ranganathan’s results, N;given by N=tan2() needs no longer be an integer. Specifically, vectors a and b must have the form a=(1,0);b=(r,tan) where r is an arbitrary rational number. We have also shown that the interfacial classification of cubic twist interfaces based on the recurrence properties of the O-lattice remains valid for arbitrary two-dimensional interfaces provided the above requirements on the lattice are met.

Phase-sensitive optical time-domain reflectometry(CDOTDR)is a well-established technique that provides spatiotemporal measurements of an environmental variable in real time.This unique capability is being leveraged in an everincreasing number of applications,from energy transportation or civil security to seismology.To date,a wide number of different approaches have been implemented,providing a plethora of options in terms of performance(resolution,acquisition bandwidth,sensitivity or range).However,to achieve high spatial resolutions,detection bandwidths in the GHz range are typically required,substantially increasing the system cost and complexity.Here,we present a novel OOTDR approach that allows a customized time expansion of the received optical traces.Hence,the presented technique reaches cm-scale spatial resolutions over t km while requiring a remarkably low detection bandwidth in the MHz regime.This approach relies on the use of dual-comb spectrometry to interrogate the fibre and sample the backscattered light.Random phase-spectral coding is applied to the employed combs to maximize the signal-to-noise ratio of the sensing scheme.A comparison of the proposed method with alternative approaches aimed at similar operation features is provided,along with a thorough analysis of the new trade-offs.Our results demonstrate a radically novel high-resolution OOTDR scheme,which could promote new applications in metrology,borehole monitoring or aerospace.

The coupledΛΛnn-Ξ-pnn system was studied to investigate whether the inclusion of channel coupling is able to bind theΛΛnn system.We use a separable potential three-body model of the coupledΛΛnn-Ξ-pnn system and a variational four-body calculation with realistic interactions.Our results exclude the possibility of aΛΛnn bound state by a large margin.Instead,we found aΞ-t quasibound state above theΛΛnn threshold.

Gamification has been applied in software engineering to improve quality and results by increasing people’s motivation and engagement.A systematic mapping has identified research gaps in the field,one of them being the difficulty of creating an integrated gamified environment comprising all the tools of an organization,since most existing gamified tools are custom developments or prototypes.In this paper,we propose a gamification software architecture that allows us to transform the work environment of a software organization into an integrated gamified environment,i.e.,the organization can maintain its tools,and the rewards obtained by the users for their actions in different tools will mount up.We developed a gamification engine based on our proposal,and we carried out a case study in which we applied it in a real software development company.The case study shows that the gamification engine has allowed the company to create a gamified workplace by integrating custom-developed tools and off-the-shelf tools such as Redmine,TestLink,or JUnit,with the gamification engine.Two main advantages can be highlighted:(i)our solution allows the organization to maintain its current tools,and(ii)the rewards for actions in any tool accumulate in a centralized gamified environment.

Sol-gel borate bioactive glasses(BGs)are promising ion-releasing biomaterials for wound healing applications.Here,we report the synthesis of a series of binary B_(2)O_(3)-CaO borate BGs(CaO ranging from 50 to 90mol%)using a sol-gel-based method.The influence of CaO content in B_(2)O_(3)-CaO borate BG on morphology,structure and ion release behavior was investigated in detail.Reduced dissolution(ion release)and crystallization could be observed in borate BGs when CaO content increased,while the morphology was not significantly altered by increasing CaO content.Our results evidenced that the ion release behavior of borate BGs could be tailored by tuning the B_(2)O_(3)/CaO molar ratio.We also evaluated the in vitro cytotoxicity,hemostatic,antibacterial and angiogenic activities of borate BGs.Cytocompatibility was validated for all borate BGs.However,borate BGs exhibited composition-dependent hemostatic,antibacterial and angiogenic activities.Generally,higher contents of Ca in borate BGs facilitated hemostatic activity,while higher contents of B_(2)O_(3) were beneficial for pro-angiogenic activity.The synthesized sol-gel-derived borate BGs are promising materials for developing advanced wound healing dressings,given their fast ion release behavior and favorable hemostatic,antibacterial and angiogenic activities.
