Phosphorus in Finnish soils in the 1900s with particular reference to the acid ammonium acetate soil test [PDF]

open access: yes, 2002
Comprehensive research into phosphorus (P) in soils and crops began in Finland in the early 1900s. The average amount of total P in the ploughed topsoil layer of mineral soils was about two tonnes per hectare in the 1930s, before the abundant use of ...

Unlocking Ultra‐Long Cycle Stability of Li Metal Electrode by Separators Modified by Porous Red Phosphorus Nanosheets

open access: yesAdvanced Functional Materials, EarlyView.
Coating the standard polypropylene separator with a porous red phosphorous nanosheet greatly improves cycling performance in Li electrode cells. The phosphorus‐based surface chemistry deactivates electrolyte solvent decomposition and enhances the cleavage of F‐containing salt, resulting in an inorganic‐dominated electrolyte interphase (SEI) composition

Dual mutualistic associations in sainfoin (Onobrychis viciifolia Scop.) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Agronomy at Massey University [PDF]

open access: yes, 1982
Recent studies established that many legumes, when infected with the appropriate Rhizobium spp. and arbuscular fungi, nodulated better and exhibited greater dinitrogen fixation than plants infected with only the rhizobia.

Photoactivation of NV Centers in Diamond via Continuous Wave Laser Illumination of Shallow As‐Implanted Nitrogen

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...

Determination of Vanadium, Iron, Manganese and Phosphorus Contents in Ferrovanadium Slag by Alkali Fusion-Inductively Coupled Plasma Atomic Emission Spectrometry

open access: yesKuangchan zonghe liyong, 2022
The ferrovanadium slag sample was fused with sodium carbonate-boric acid at high temperature, then acidified with hydrochloric. Vanadium 310.230 nm, iron 259.940 nm, manganese 257.610 nm and phosphorus 213.618 nm were selected as the analytical lines ...

Prediction of soil available phosphorus based on soil organic carbon [PDF]

open access: yes, 2008
There are many cases in which it is desirable to determine relationships among some soil physical and chemical properties. In soil studies, soil available phosphorous (AP) are often determined using laboratory tests, but it may be more suitable and ...

Enhancing Direct Solar Water Splitting via ALD of Multifunctional TiO2/Pt Nanoparticle Coatings With Engineered Interfaces to GaAs/GaInP Tandem Cells

open access: yesAdvanced Functional Materials, EarlyView.
Multifunctional atomic layer deposited coatings and interface treatments enhance direct solar water splitting on GaAs/GaInP tandem cells. Optimized TiO2/Pt nanoparticle bilayers ensure durability and catalytic efficiency with minimal optical losses, while H2 plasma pretreatments maximize photovoltage and interfacial charge extraction.

Effect of Hydroxide-Based Ionic Liquids on the Determination of Available Phosphorus in Alkaline Soils

open access: yesYankuang ceshi
The level of available phosphorus in soil significantly impacted plant growth, soil fertility, and agricultural productivity. However, in alkaline soils, phosphorus mobility was low and was often tightly bound to minerals and organic matter, complicating
