Genetic Parameters and Prediction of Breeding Values in Switchgrass Bred for Bioenergy
Authors: Edmé Serge , Mitchell Robert , Sarath Gautam
Published: March 2017

Estimating genetic parameters is an essential step in breeding by recurrent selection to maximize genetic gains over time. This study evaluated the effects of selection on genetic variation across two successive cycles (C1 and C2) of a ‘Summer'x‘Kanlow’ switchgrass (Panicum virgatum L.) population. Two progeny tests were planted in 2007 and 2011 near Mead, NE and respectively analyzed for 2 and 4 yr. Each test was a randomized complete block design, with four replicates of 34 halfsib families in single‐row plots of 10 seedlings in C1 and with three replicates of 111 halfsib families in single‐row plots of five seedlings in C2. The C2 test included C0, C1, and parental populations for comparison. Multivariate mixed linear models revealed ample additive genetic variation for dry matter yield (DMY), Klason lignin (KL), and predicted ethanol yield (ETOH) in both cycles, with heritability ranging from 0.40±0.18 to 0.5±0.14 at the family level, from 0.22±0.17 to 0.36±0.22 at the individual level, and from 0.25 to 0.31 within family in C1. Matching values in C2 were: from 0.42±0.09 to 0.63±0.07, from 0.10±0.07 to 0.34±0.13, and from 0.12 to 0.48. More opportunity exists to improve DMY, with a coefficient of additive genetic variation of 11 to 32%, than KL (3–5%) or ETOH (3–6%). The traits were properly aligned for joint improvement for high DMY and reduced KL in C1, owing to favorable genetic correlations (rA=−0.33±0.11) and each having respective rA of 0.60±0.05 and −0.62±0.07 with ETOH. In C2, the rA between DMY and KL (−0.19±0.10) or ETOH (0.04±0.04) decreased towards zero, and that between KL and ETOH was moderately less negative (−0.35±0.15). These results suggest a strong genetic basis for improvement of the traits and monitoring of their patterns every cycle to find the proper weights that maximize the breeding goal of designing the ideal bioenergy switchgrass.

Published: March 2017

This work introduces the symbiotic organisms search (SOS) evolutionary algorithm to the optimization of reservoir operation. Unlike the genetic algorithm (GA) and the water cycle algorithm (WCA) the SOS does not require specification of algorithmic parameters. The solution effectiveness of the GA, SOS, and WCA was assessed with a single-reservoir and a multi-reservoir optimization problem. The SOS proved superior to the GA and the WCA in optimizing the objective functions of the two reservoir systems. In the single reservoir problem, with global optimum value of 1.213, the SOS, GA, and WCA determined 1.240, 1.535, and 1.262 as the optimal solutions, respectively. The superiority of SOS was also verified in a hypothetical four-reservoir optimization problem. In this case, the GA, WCA, and SOS in their best performance among 10 solution runs converged to 97.46%, 99.56%, and 99.86% of the global optimal solution. Besides its better performance in approximating optima, the SOS avoided premature convergence and produced lower standard deviation about optima.
Numerical modeling of the effects of pumping on tide-induced groundwater level fluctuation and on the accuracy of the aquifer's hydraulic parameters estimated via tidal method: a case study in Donghai Island, China
Authors: Zhou Pengpeng , Qiao Xiaojuan , Li Xiaolei
Published: March 2017

Coastal groundwater level is affected both by tide and pumping. This paper presents a numerical model to study the effects of pumping on tide-induced groundwater level fluctuation and on accuracy of hydraulic parameters estimated via tidal method. Firstly, for the effects of pumping on the groundwater level fluctuation under the combined influence of pumping and tide, groundwater level has a drawdown but eventually reaches a quasi-steady-state again. Steady pumping can attenuate the amplitude but cannot affect the phase of the quasi-steady fluctuation. However, seaward steady pumping plays a relatively obvious role in enhancing drawdown compared with landward pumping, a partial penetration well leads to greater drawdown than a full penetration well, and transient pumping induces large amplitude which does not reflect large transmissivity. Secondly, for the effects of pumping on the accuracy of the parameter estimated via the tidal method, transient pumping or large steady pumping, especially in a full penetration well, significantly affects accuracy of the estimated parameters. However, when the distance between the pumping well and tide observation well exceeds 200% of the distance between observation well and shoreline, pumping effect on estimated parameters can be neglected. The conclusions could provide guidance for reasonable application of the tidal method.
Damming water influences the structure, composition and functions of adjacent savannahs

Published: March 2017

Dams are important to human wellbeing; however, they can cause various environmental changes. In the cerrado stricto sensu, waters from the reservoir modify water supply in the soil and can affect species establishment. It is argued that species adapted to high water availability can establish close to river banks and water reservoirs and their characteristics are different from those of species from the cerrado stricto sensu. These characteristics could be more similar to those of species from riparian forests, with higher values of height and basal area. Thus, we aim to analyze changes in an area of the cerrado stricto sensu, 35 years after the construction of a hydroelectric dam. We tested different parameters to determine these changes, including richness, diversity, individual height and basal area (using the square-point method), with individuals <1 m, individuals >1 m, and Bromeliaceae (using the plot method) in three sectors close to the artificial lakeshore (0 m - 20 m, 40 m - 60 m, and 80 m - 100 m away from the water). Using species diversity, we also compared the species functional group within these sectors. Sectors closer to the dam acted as an edge, presenting lower basal area and individual’s height, but species with different traits compared to those of a cerrado stricto sensu area.ResumoRepresas são importantes para o bem-estar humano, no entanto, podem causar diversas alterações nos ambientes. No cerrado stricto sensu, as águas represadas modificam o abastecimento de água no solo e podem alterar o estabelecimento das espécies. Argumenta-se que as espécies adaptadas à alta disponibilidade de água podem estabelecer-se próximo às margens de rios e reservatórios e possuem características distintas daquelas de espécies de cerrado stricto sensu. As características seriam mais semelhantes àquelas de espécies de matas ciliares, com elevada estatura e área basal. Assim, almejamos analisar as mudanças em uma área de cerrado stricto sensu após 35 anos sob a influência de uma usina hidrelétrica. Testamos parâmetros distintos para determinar essas mudanças, tais como a riqueza, a diversidade, altura dos indivíduos e área basal (utilizando o método do ponto quadrante), com indivíduos < 1 m, indivíduos > 1 m e Bromeliaceae (utilizando o método de parcelas) em três setores próximo à margem da represa (a 0 m - 20 m, 40 m - 60 m e 80 m - 100 m da represa). Utilizando a diversidade de espécies, também comparamos os grupos funcionais de espécies nesses setores. Os setores mais próximos à represa possuíam baixa área basal e altura dos indivíduos atuando como uma borda, mas com espécies com diferentes características em relação ao cerrado stricto sensu.Palavras chave: acumulação de biomassa, cerrado stricto sensu, comunidade  arbórea, energia hidroelétrica, fitossociologia, grupos funcionais, traços funcionais.

Lendo e compartilhando Jane Jacobs
Authors: Cymbalista Renato
Published: March 2017

Ironicamente, o sucesso indiscutível d obra de Jane Jacobs tem como uma de suas vítimas o seu livro mais importante, "Morte e vida das grandes cidades americanas": quanto mais ele é citado, menos é lido, pois temos cada vez mais a impressão de que conhecemos a autora e suas ideias. Uma das atividades da disciplina “História do Urbanismo Contemporâneo” da FAU-USP no segundo semestre de 2016 foi a leitura e discussão coletiva do livro, com o intuito de ir além da fala genérica sobre Jane Jacobs. Como o tempo para a leitura da obra inteira não estava à disposição dos estudantes em meio às imensa sobrecarga de trabalho, foi feita uma dinâmica de leitura compartilhada: as 23 seções do livro foram divididas pela turma, e cada um foi lida por 2 a 3 alunos. Os alunos foram divididos em 4 grupos, correspondentes às 4 partes do livro, e em um primeiro momento houve uma discussão de cada parte. Cada grupo escolheu um relator, que trouxe as principais ideias-força de cada parte. Mais do que resumir o livro, a pergunta era sobre a atualidade de suas ideias: em que medida “Morte e vida” traz discussões ainda pertinentes para a contemporaneidade, e em que medida merece uma leitura mais distanciada e historiográfica? O veredito do grupo indicou que a obra é, em grande medida, atual, em que pesem elementos anacrônicos e por demais referentes à realidade urbana norte-americana de meados do século XX

Sobre el resentimiento y el perdón
Authors: Gibu Shimabukuro Ricardo
Published: March 2017

Recibido: 3/12/2015 • Aceptado: 27/01/2016

El presente trabajo es una reflexión en torno a la naturaleza del resentimiento y su poderoso influjo en el orden social. En diálogo con la caracterización del resentimiento propuesta por Scheler en su Das Ressentiment im Aufbau der Moralen  (1912), se describe la particular forma de violencia implicada en esta disposición afectiva. La sed de venganza que la anima promueve una dinámica incesante de ataques y contraataques que sólo puede resolverse a través del perdón. Si sólo es posible perdonar a través del amor, ¿dónde halla el agredido la fuerza para amar al agresor? En la última parte del trabajo, se busca dar respuesta a esta cuestión en una línea muy cercana a la del teólogo alemán Romano Guardini.

Takođe, date su i preporuke za primenu drugih propisa koje dopunjuju pomenute smernice. Imajući u vidu značaj sistema KGH, preporučuje se testiranje i niskopritisnih kanalskih mreža na zaptivenost.
Osnovne postavke standarda kvaliteta čvrstih biogoriva iz sekundarnih drvnih sirovina
Authors: Petrović Predrag , Petrović Marija
Published: March 2017

Čvrsta biogoriva iz sekundarnih drvnih sirovina, predstavljaju značajan izvor obnovljive energije. Pored drvnih sekundarnih sirovina u primeni se nalaze i sekundarne sirovine iz: poljoprivrede, voćarstva, prehrambene industrije, komunalnog i drugog otpada. Sekundarni drvni otpad je veoma prihvatljiv kao obnovljivi izvor energije, kojem se u svetu pridaje velika pažnja kroz definisanje standarda kvaliteta. Međutim, određeni drvni otpad, na primer iz građevinarstva i drvne industrije, može sadržati halogena organska jedinjenja ili teške metale kao rezultat tretmana drveta sredstvima zaštite i premaza i u njihovim produktima sagorevanjem mogu se naći ekološki neželjeni elementi. U tehnološkim operacijama pri: proizvodnji, kontrolisanju, laboratorijskim analizama, trgovini i korišćenju čvrstih biogoriva, primena tehničke regulative je neophodna kako bi se obezbedili svi neophodni postupci u celokupnom tehnološko-proizvodnom lancu. Primena zahteva standarda je neophodna i zbog sprečavanja stvaranja i emisije štetnih produkata sagorevanja, odnosno u cilju očuvanja i zaštite životne sredine. Srbija nije član Evropskog komiteta za standarde (CEN), ali kao kandidat za članstvo u Evropskoj uniji, ali i u okviru mnogobrojnih političko-ekonomskih mera, mora usaglasiti i mnogobrojne različite regulative, u koje spada i set standarda koji se odnose na kvalitet čvrstih drvnih biogoriva. Set serije standarda za čvrsta biogoriva, pruža nedvosmislene i jasne principe klasifikacije, koji služe kao alat kojim se omogućava njihova efikasna trgovina, dobro razumevanje između prodavca i kupca, kao i dobra komunikacija sa proizvođačima opreme. Standardi u ovoj oblasti su veoma obimni i studiozni i obuhvataju celokupan lanac proizvodnje, kontrole kvaliteta i karakteristika, snabdevanja, isporuke, korišćenja i drugih neophodnih tehnoloških postupaka, a sve u cilju kvalitativnog zadovoljenja krajnjeg korisnika. U ovom radu su prikazane neke osnovne smernice standarda kvaliteta za čvrsta biogoriva, proizvedena od sekundarnih produkata šumske i drvne industrije, pre svega sa aspekta podizanja energetske efikasnosti i očuvanja i zaštite životne sredine.

The study aimed to evaluate 1) whether the PAKEM plan carried out as a fulfillment of the standardized goal-oriented learning plan. 2) The performance of PAKEM learning carried out looking into whether it is in accordance with the goal-oriented plans. 3)The outputs of PAKEM learning, measured by the achievement of the learning objectives. The research conducted here has applied an evaluative approach using both quantitative and qualitative methodology. This research was conducted in SMPN 2 Boja Kendal regency. The respondents assigned to the research were principal, 20 classroom teachers of IX grade and 30 students of class IX C. The data collection techniques used observation, documentation study and interview. The quantitative data analysis was conducted to gain the results of the data of observation and of studying the documents, whereas the qualitative data analysis was carried out to examine the results of the interviews. The research showed that (1) the PAKEM learning plan carried out had fulfilled the standardized goal-oriented learning plan. Nevertheless, the teachers’ competence in selecting and making use of teaching media needs improving. Teachers as individuals or with the support of school may do this either. (2) The performance of PAKEM learning carried out has been done well in accordance with the goal-oriented plan because all the teachers have achieved good grades of teaching performance. However, to enhance their teaching performance, it is necessary for the teachers to improve their competence in making use of the available learning and teaching sources, teaching media and in assessing the students learning. (3) The outputs of PAKEM learning have been able to measure the goal achievement of learning. This has been proven by the fact that a lot of students have passed most of the school subjects (8 subjects) achieving grades higher than the minimum grades required to pass them. Referring to the minimum grade required to pass the subjects, only a few students have not passed 4 of them. Nevertheless, school needs to gradually raise the minimum passing grade in order to be equal to the national one.

PRESERVICE TEACHERS ON TEACHING WITH AND ABOUT ICT: AN INDONESIAN STUDY
Authors: Relmasira Stefanus Christian , Thrupp Rose-Marie
Published: March 2017

Teaching about and with digital technologies continues to challenge teachers. Aligned with the permeation of Information Communication Technologies (ICT) in our daily lives is the challenge of ICT in the classroom. Curriculum writers strive to identify declarative and procedural knowledge needed by future citizens. Teachers strive to design ICT-enabled learning that engages contemporary learners.  The identity of a teacher of ICT and using ICT for learning challenges preservice teachers as they create their own identity in the classroom.  These challenges cross borders, both geographical and cultural. Using a research approach developed by Hunt (2015), preservice teachers in a teacher education program in Central Java, Indonesia were asked to draw what teachers and ICT look like, sound like, and feel like. This study builds upon the ideas of Goodenough (1926) and Chambers (1983) to examine the views of teachers and ICT held by preservice teachers. These findings can inform the design of teacher education programs in supporting preservice teachers to build their self-efficacy as teachers teaching with and about ICT in their classroom and contribute to the construction of professional learning post-graduation.

One of the primary goals for the oilseed sunflower (Helianthus annuus L.) industry is to provide novel oil products for human consumption. One oil profile of particular interest is high oleic and low saturated fat, because it combines high oxidative stability of the oil with a reduction in the fatty acids that are detrimental to human health, namely saturated and trans‐fats. In addition, traits that contribute to ease of production, such as tolerance to common herbicides, are also required in modern cultivars. We describe the development of lines that combine imidazolinone herbicide tolerance and a favorable genetic background with a high oleic, low saturated fat profile in the seed oil. HOLS1 (Reg. No. GS‐58, PI 678787), HOLS2 (Reg. No. GS‐59, PI 678788), HOLS3 (Reg. No. GS‐60, PI 678789), and HOLS4 (Reg. No. GS‐61, PI 678790) are maintainer inbred genetic stocks that were developed using backcross and pedigree methods, with testing of each generation for fatty acid composition in the seed oil and confirmation of imidazolinone tolerance in later generations. These lines were released by the USDA‐ARS and the North Dakota Agricultural Experiment Station, Fargo, to fill the urgent need for useful variation in fatty acid composition in oilseed sunflower.

Six upland cotton (Gossypium hirsutum L.) germplasm lines, M Rk‐Rn 1(Reg. No. GP‐1015, PI 678938), M Rk‐Rn 2 (Reg. No. GP‐1016, PI 678939), M Rk‐Rn 3 (Reg. No. GP‐1017, PI 678940), M Rk‐Rn 4 (Reg. No. GP‐1018, PI 678941), M Rk‐Rn 5 (Reg. No. GP‐1019, PI 678942), and M Rk‐Rn 6 (Reg. No. GP‐1020, PI 78943), with resistance to root‐knot nematode [Meloidogyne incognita (Kofoid and White) Chitwood], and reniform nematode (Rotylenchulus reniformis Linford and Oliveria) were jointly released by the USDA‐ARS and the Mississippi Agricultural and Forestry Experiment Station in 2016. The source of resistance to root‐knot nematode was M‐240 RNR (PI 592511) and to reniform nematode was M713 Ren1 (PI 665928). The two lines were crossed and plants were selected using markers with subsequent crosses to ‘Sure‐Grow 747’ (PI 656375), followed by marker selection. The germplasm lines were selected using simple sequence repeat (SSR) markers CIR 316 and BNL 3661 that are linked to root‐knot resistance and GH 132, BNL 3279, and BNL 569 that are linked to reniform resistance genes. Egg production of root‐knot and reniform nematodes was suppressed significantly from the susceptible check Sure‐Grow 747 in growth chamber tests. In addition to resistance to both nematodes, these lines, which also exhibit differences for agronomic and fiber traits such as length, strength, and micronaire, should be valuable to cotton breeding programs. The successful use of these specific SSR markers further validates their use in selection of nematode‐resistant plants in segregating generations.

Impact of Practice Change on Runoff Water Quality and Vegetable Yield—An On-Farm Case Study
Authors: Nachimuthu Gunasekhar , Halpin Neil , Bell Michael
Published: March 2017

Intensive agricultural practices in farming systems in eastern Australia have been identified as a contributor to the poor runoff water quality entering the Great Barrier Reef (GBR). A field investigation was carried out to measure the off-farm water quality and productivity in a coastal farming system in northeastern Australia. Two vegetable crops (capsicum and zucchini) were grown in summer 2010–2011 and winter 2011 respectively using four different management practices (Conventional—plastic mulch, bare inter-row conventional tillage and commercial fertilizer inputs; Improved—improved practice with plastic mulch, inter-row vegetative mulch, zonal tillage and reduced fertilizer rates; Trash mulch—improved practice with cane-trash or forage-sorghum mulch with reduced fertilizer rates, minimum or zero tillage; and Vegetable only—improved practice with Rhodes grass or forage-sorghum mulch, minimum or zero tillage, reduced fertilizer rates). Results suggest improved and trash mulch systems reduced sediment and nutrient loads by at least 50% compared to conventional systems. The residual nitrate nitrogen in soil accumulated at the end-of-break crop cycle was lost by deep drainage before the subsequent sugarcane crop could utilize it. These results suggest that future research into establishing the linkages between deep drainage, groundwater quality and lateral movement into adjacent streams is needed. The improvement in runoff water quality was accompanied by yield reductions of up to 55% in capsicum and 57% in zucchini under trash mulch systems, suggesting a commercially unacceptable trade-off between water quality and productivity for a practice change. The current study has shown that variations around improved practice (modified nutrient application strategies under plastic mulch, but with an inter-space mulch to minimize runoff and sediment loss) may be the most practical solution to improve water quality and maintain productivity. However, more work is required to optimize this approach and thus reduce the size of any potential productivity and profitability gap that would necessitate an expensive policy intervention to implement.

Published: March 2017

A new elastoplastic J 2 -flow models with thermal effects is proposed toward simulating thermo-coupled finite deformation behaviors of shape memory polymers. In this new model, an elastic potential evolving with development of plastic flow is incorporated to characterize the stress-softening effect at unloading and, moreover, thermo-induced plastic flow is introduced to represent the strain recovery effect at heating. It is shown that any given test data for both effects may be accurately simulated by means of direct and explicit procedures. Numerical examples for model predictions compare well with test data in literature.

Entrained air voids can improve the freeze-thaw durability of concrete, and also affect its mechanical and transport properties. Therefore, it is important to measure the air void structure and understand its influence on concrete performance for quality control. This paper aims to measure air void structure evolution at both early-age and hardened stages with the ultrasonic technique, and evaluates its influence on concrete properties. Three samples with different air entrainment agent content were specially prepared. The air void structure was determined with optimized inverse analysis by achieving the minimum error between experimental and theoretical attenuation. The early-age sample measurement showed that the air void content with the whole size range slightly decreases with curing time. The air void size distribution of hardened samples (at Day 28) was compared with American Society for Testing and Materials (ASTM) C457 test results. The air void size distribution with different amount of air entrainment agent was also favorably compared. In addition, the transport property, compressive strength, and dynamic modulus of concrete samples were also evaluated. The concrete transport decreased with the curing age, which is in accordance with the air void shrinkage. The correlation between the early-age strength development and hardened dynamic modulus with the ultrasonic parameters was also evaluated. The existence of clustered air voids in the Interfacial Transition Zone (ITZ) area was found to cause severe compressive strength loss. The results indicated that this developed ultrasonic technique has potential in air void size distribution measurement, and demonstrated the influence of air void structure evolution on concrete properties during both early-age and hardened stages.

A novel development on halloysite-polyvinyl alcohol (HNTs-PVA) nanocomposites has been conducted using malonic acid (MA) by crosslinking PVA and HNTs. PVA-MA crosslinking produces smooth surfaces, which play an important role in enhancing the properties of HNTs-PVA nanocomposite. The crystallographic structures of crosslinked HNTs-PVA show almost no change as depicted by the X-ray diffraction (XRD)-2θ-peak, suggesting that MA has no or little influence on the crystallographic structure of the HNTs-PVA. Images taken by field emission scanning electron microscope (FESEM) suggest possible effects of MA on the morphology and internal features of HNTs-PVA by reducing the agglomeration of HNTs, which is considered a decisive step in improving the surface qualities of HNTs. Investigating the samples using the Brunauer–Emmelt–Teller (BET) technique showed that the surface area was increased by about 10 times, reaching the second highest recorded results compared to the HNTs, which could be considered a breakthrough step in enhancing the properties of HNTs-PVA due to MA crosslinking.

RNAs are central to all gene expression through the control of protein synthesis. Four major nucleosides, adenosine, guanosine, cytidine and uridine, compose RNAs and provide sequence variation, but are limited in contributions to structural variation as well as distinct chemical properties. The ability of RNAs to play multiple roles in cellular metabolism is made possible by extensive variation in length, conformational dynamics, and the over 100 post-transcriptional modifications. There are several reviews of the biochemical pathways leading to RNA modification, but the physicochemical nature of modified nucleosides and how they facilitate RNA function is of keen interest, particularly with regard to the contributions of modified nucleosides. Transfer RNAs (tRNAs) are the most extensively modified RNAs. The diversity of modifications provide versatility to the chemical and structural environments. The added chemistry, conformation and dynamics of modified nucleosides occurring at the termini of stems in tRNA’s cloverleaf secondary structure affect the global three-dimensional conformation, produce unique recognition determinants for macromolecules to recognize tRNAs, and affect the accurate and efficient decoding ability of tRNAs. This review will discuss the impact of specific chemical moieties on the structure, stability, electrochemical properties, and function of tRNAs.

QueF enzymes catalyze the nicotinamide adenine dinucleotide phosphate (NADPH)-dependent reduction of the nitrile group of 7-cyano-7-deazaguanine (preQ0) to 7-aminomethyl-7-deazaguanine (preQ1) in the biosynthetic pathway to the tRNA modified nucleoside queuosine. The QueF-catalyzed reaction includes formation of a covalent thioimide intermediate with a conserved active site cysteine that is prone to oxidation in vivo. Here, we report the crystal structure of a mutant of Bacillus subtilis QueF, which reveals an unanticipated intramolecular disulfide formed between the catalytic Cys55 and a conserved Cys99 located near the active site. This structure is more symmetric than the substrate-bound structure and exhibits major rearrangement of the loops responsible for substrate binding. Mutation of Cys99 to Ala/Ser does not compromise enzyme activity, indicating that the disulfide does not play a catalytic role. Peroxide-induced inactivation of the wild-type enzyme is reversible with thioredoxin, while such inactivation of the Cys99Ala/Ser mutants is irreversible, consistent with protection of Cys55 from irreversible oxidation by disulfide formation with Cys99. Conservation of the cysteine pair, and the reported in vivo interaction of QueF with the thioredoxin-like hydroperoxide reductase AhpC in Escherichia coli suggest that regulation by the thioredoxin disulfide-thiol exchange system may constitute a general mechanism for protection of QueF from oxidative stress in vivo.

Automotive and stationary energy storage are among the most recently-proposed and still unfulfilled applications for lithium ion devices. Higher energy, power and superior safety standards, well beyond the present state of the art, are actually required to extend the Li-ion battery market to these challenging fields, but such a goal can only be achieved by the development of new materials with improved performances. Focusing on the negative electrode materials, alloying and conversion chemistries have been widely explored in the last decade to circumvent the main weakness of the intercalation processes: the limitation in capacity to one or at most two lithium atoms per host formula unit. Among all of the many proposed conversion chemistries, hydrides have been proposed and investigated since 2008. In lithium cells, these materials undergo a conversion reaction that gives metallic nanoparticles surrounded by an amorphous matrix of LiH. Among all of the reported conversion materials, hydrides have outstanding theoretical properties and have been only marginally explored, thus making this class of materials an interesting playground for both fundamental and applied research. In this review, we illustrate the most relevant results achieved in the frame of the Italian National Research Project FIRB 2010 Futuro in Ricerca “Hydrides as high capacity anodes in lithium cells” and possible future perspectives of research for this class of materials in electrochemical energy storage devices.
