Gallium Microalloying in Bi–Sn Solders: Interfacial Phase Formation, Wettability, and Long‐Term Shear Reliability Under Isothermal Aging

open access: yesAdvanced Engineering Materials, EarlyView.
Gallium microalloying redirects interfacial reactions in low‐temperature Bi–Sn solders from Cu–Sn toward Cu–Ga intermetallic formation. The resulting Cu–Ga layer suppresses intermetallic growth during thermal aging, alters fracture pathways, and improves interfacial stability.

Denitrification by rhizobia: A possible factor contributing to nitrogen losses from soils [PDF]

open access: yes, 1980
The intensive pastoral farming system on which New Zealand animal production is based is almost completely dependent upon the rhizobium-legurne symbiosis for the fixed nitrogen required for pasture production.

Effect of Phosphorus Supply Levels on Nodule Nitrogen Fixation and Nitrogen Accumulation in Soybean (Glycine max L.)

open access: yesAgronomy, 2022
The specific mechanism by which phosphorus affects nodule nitrogen fixation and nitrogen absorption in soybeans remains inconclusive. To further quantitatively analyze the effect of phosphorus on nodule nitrogen fixation and nitrogen accumulation in ...

Impact of Hydrogen Incorporation on Electronic and Magnetic Structure of X2CrNi18‐9 Stainless Steel

open access: yesAdvanced Engineering Materials, EarlyView.
Hydrogen uptake in austenitic stainless steel alters both its electronic and magnetic structure. Seebeck measurements reveal hydrogen‐induced shifts in the electronic density of states, while neutron scattering uncovers nanoscale inhomogeneities that grow upon hydrogen incorporation, with the most pronounced effect observed in the PBF as‐built state ...

Biological nitrogen fixation of Biserrula pelecinus L. under water deficit [PDF]

open access: yes, 2012
The present work studied the effects of water deficiency conditions on the biological nitrogen fixation of three na- tive rhizobia (SafPt12, SafPt6, and AjuPt16) isolated from Biserrula pelecinus L., and a reference strain Mesorhizo- bium ciceri biovar ...

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

open access: yesAdvanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Identifying Mechanisms of Putative Drought Tolerance in New Cotton and Soybean Genotypes Under Rainfed Field Conditions

open access: yesAgronomy
New drought-tolerant row crop germplasm may help reduce risk under drought conditions in the southeastern U.S., but how these genotypes adapt to drought is poorly understood.

A Novel Nitrogen-Fixing Bacterium Raoultella electrica Isolated from the Midgut of the Leafhopper Recilia dorsalis

open access: yesInsects, 2023
Nitrogen is a crucial element for the growth and development of insects, but herbivorous insects often suffer from nitrogen nutrition deficiencies in their diets.

Dynamically Actuated Reconfigurable Topographical Surface Enables Active Control of Implant‐Associated Infections

open access: yesAdvanced Functional Materials, EarlyView.
A dynamically actuated reconfigurable topographical surface (DARTS) integrates contact‐mediated bactericidal nanotopography with programmable mechanical actuation to actively disrupt bacterial biofilms. Dynamic surface reconfiguration enhances bacterial killing and suppresses implant‐associated infections in vivo, providing a new strategy for active ...

New hints on nutrients dynamics and their impact on carbon sequestration in the Mediterranean Sea [PDF]

open access: yes, 2009
In the World Ocean nitrogen and phosphorus cycles are deeply linked to the carbon cycle. As nitrate and phosphate play an important role in controlling biological production, the intensity of atmospheric carbon sequestration is strongly influenced by ...
