“…It can be seen that lithium ion forms a chemical bond not only with the nitrogen atom, but also with the BH 3 unit through intramolecular Li¨¨¨H-B interactions. The binding energy of BH 3 to NMe 2 Li appears to be significant, ∆E total =´63.99 kcal/mol, Figure 3B. Just for comparison, the binding energy of BH 3 to ammonia in NH 3 BH 3 is only´30.3 kcal/mol [13].…”

“…An increase in energy consumption as well as the environmental harmfulness of current coal or hydrocarbon based fuels has led to intensive search for alternative energy sources [1][2][3]. Therefore, various hydrogen storage materials, that contain significant amounts of hydrogen, have been recently proposed.…”

Abstract:In the present work, an in-depth, qualitative and quantitative description of non-covalent interactions in the hydrogen storage materials LiN(CH 3 ) 2 BH 3 and KN(CH 3 ) 2 BH 3 was performed by means of the charge and energy decomposition method (ETS-NOCV) as well as the Interacting Quantum Atoms (IQA) approach. It was determined that both crystals are stabilized by electrostatically dominated intra-and intermolecular M¨¨¨H-B interactions (M = Li, K). For LiN(CH 3 ) 2 BH 3 the intramolecular charge transfer appeared (B-HÑLi) to be more pronounced compared with the corresponding intermolecular contribution. We clarified for the first time, based on the ETS-NOCV and IQA methods, that homopolar BH¨¨¨HB interactions in LiN(CH 3 ) 2 BH 3 can be considered as destabilizing (due to the dominance of repulsion caused by negatively charged borane units), despite the fact that some charge delocalization within BH¨¨¨HB contacts is enforced (which explains H¨¨¨H bond critical points found from the QTAIM method). Interestingly, quite similar (to BH¨¨¨HB) intermolecular homopolar dihydrogen bonds CH¨¨¨HC appared to significantly stabilize both crystals-the ETS-NOCV scheme allowed us to conclude that CH¨¨¨HC interactions are dispersion dominated, however, the electrostatic and σ/σ*(C-H) charge transfer contributions are also important. These interactions appeared to be more pronounced in KN(CH 3 ) 2 BH 3 compared with LiN(CH 3 ) 2 BH 3 .

“…W skali przemysłowej największe ilości wodoru otrzymuje się w wyniku konwersji gazu ziemnego [4,6] w obecności pary wodnej i katalizatora. Obserwuje się postępy w technologii konwersji różnych surowców [13,55] i metanolu [26] do wodoru, ale największe zainteresowanie w ostatnich latach wzbudza otrzymywanie wodoru na drodze fotokatalitycznego rozkładu wody z zastosowaniem odnawialnej energii słonecznej [9,22,25]. W ocenie autorów najlepszym źródłem informacji na temat postępów w przechowywaniu wodoru jest monografia [62].…”

“…[3]. Traditionally, H 2 is industrially produced by energy intensive processes, such as steam reforming of natural gas, gasification of coal, and water electrolysis [4]. In recent years, dark fermentative H 2 production has become a promising method for sustainable practical applications owing to simple reactor configuration, mild operation conditions, and high H 2 production rate [5].…”

Temperature Seed sludgeCorn stover hydrolyzate Denaturing gradient gel electropho- resis (DGGE)Microbial diversity analysis a b s t r a c tThe temperature effect on fermentative hydrogen (H 2 ) production from corn stover hydrolyzate was investigated under mesophilic (37 and 30 C), thermophilic (55 C), and extreme thermophilic (70 C) conditions by using two typical seed sludges (activated sludge and anaerobic granular sludge). Among various temperatures, the fermentation at 55 C reached the optimal H 2 production with the values of 6.08 mmol-H 2 /g-utilized sugar for activated sludge and 7.74 mmol-H 2 /g-utilized sugar for anaerobic granular sludge, respectively. For the two seed sludges, the effectiveness of fermentation temperature on H 2 production both followed the order as 55 C > 70 C > 37 C z 30 C. The soluble metabolites composition at 55 C showed the highest acetate and butyrate concentrations, as well as the minimum ethanol production, coinciding with better H 2 -producing performances in these cases. Microbial community analysis indicated that microbial community diversity significantly decreased with increased fermentation temperature. Facultative anaerobes, such as Enterobacter spp., Klebsiella spp., and Citrobacter spp., were dominant in microbial community of the two seed sludges. As efficient H 2 producers, Bacillus sp. AB5283 in activated sludge and Thermoanaerobacterium sp. PO-2009 in anaerobic granular sludge might be mainly responsible for high H 2 yields under thermophilic condition.
