The storage of information in biological memory relies on changes in neuronal circuits, termed plasticity. Synaptic contributions to plasticity, which are an important component, may be divided into changes in existing synapses, and changes in interneuronal connectivity through formation and elimination of synapses. Interneuronal connectivity changes may be further divided into contributions as...

native population of raspberry fruits (rubus spp) were treated with methyl jasmonate (mj) fumigation and were assayed for the antioxidant capacity, total anthocyanins and postharvest quality after 7 days storage at 4?c. the result of experiment revealed that berries treated with methyl jasmonate (mj) showed higher antioxidant capacity and total anthocyanins compared to the controled ones (non...

Abstract A balance between soil water and air is needed to optimize microbial activity in laboratory incubations. Some fraction of holding capacity (WHC) often used during controlled incubations, yet this level may differ among soils. This study was undertaken develop relationships gravimetric volumetric content, WHC, water‐filled pore space (WFPS) a variety soils, representing eight orders, 46...

Borane amine compounds hold promise in a chemical hydrogen storage setting due to their high gravimetric and volumetric content of releasable hydrogen. The heats of formation and the thermodynamics of the dehydrogenation of N-methyl substituted cyclodi-, cyclotriand cyclotetraborazane were predicted at the G3(MP2) level following B3LYP/DGDVZP2 level optimization. The dehydrogenation of the N-me...

Quick on the uptake: A multiscale theoretical method predicts that the gravimetric adsorption capacities of H(2) in Li-doped covalent organic frameworks based on the building blocks shown (Li violet, H white, B pink, C green, O red, Si yellow) can reach nearly 7 % at T=298 K and p=100 bar, suggesting that these Li-doped materials are promising adsorbents for hydrogen storage.

Rare earth (RE) borohydrides have received considerable attention during the past ten years as possible hydrogen storage materials due to their relatively high gravimetric hydrogen density. This review illustrates the rich chemistry, structural diversity and thermal properties of borohydrides containing RE elements. In addition, it highlights the decomposition and rehydrogenation properties of ...

Metal-organic frameworks (MOFs) are an emerging class of microporous, crystalline materials with potential applications in the capture, storage, and separation of gases. Of the many known MOFs, MOF-5 has attracted considerable attention because of its ability to store gaseous fuels at low pressure with high densities. Nevertheless, MOF-5 and several other MOFs exhibit limited stability upon exp...

We study polylithiated molecules as building blocks for hydrogen storage materials, using first-principles calculations. CLi4 and OLi2 bind 12 and 10 hydrogen molecules, respectively, with an average binding energy of 0.10 and 0.13 eV, leading to gravimetric densities of 37.8 and 40.3 weight % H. Bonding between Li and C or O is strongly polar and H2 molecules attach to the partially charged Li...
