Black phosphorous (BP) is is recently unveiled as a promising two-dimensional direct bandgap semiconducting material. Here, we report the ambipolar field effect transistor behavior of multilayers of BP with ferromagnetic tunnel contacts. We observe a reduced of Schottky barrier < 50 meV by using TiO2/Co contacts, which could be further tuned by gate voltages. Eminently a good transistor perform...

Abstract Aims Plant investment in sexual reproduction is affected by nitrogen (N): phosphorus (P) stoichiometry. It has been suggested that an important adaptation to strong P limitation reduced reproduction. We aim investigate the specific influence of N:P on performance within and between grassland species. Methods Eleven species were selected ten plots covering N limitation, co-limitation li...

Phosphorus (P) loss from cropland to ground and surface waters is a global concern. In cold climates (CCs), freeze–thaw cycles, snowmelt runoff events, seasonally wet soils increase P potential while limiting removal effectiveness of riparian buffer zones (RBZs) other practices. While RBZs can help reduce particulate transfer streams, attenuation dissolved forms more challenging. Moreover, tran...

Background/Objective: Hyperphosphatemia is the consequence of end stage renal failure. Inadequate control of serum phosphorus results in elevated Ca×P product with subsequent soft tissue deposition in the form of conjunctival and corneal calcification.  In this study, we evaluated the relationship of conjunctival and corneal calcification with secondary hyperparathyroidism in hemodialysis patie...

In this research, novel functionally graded Ni-P coating was deposited with electroless process. The content of phosphorus was controlled to change gradual through the thickness of the coating. During the plating, bath temperature and pH were changed at specified intervals to obtain functionally graded structure. To compare the properties of functionally graded coating with Ni-P single-layer co...

the mean of all PTH, calcium and phosphorus measurements obtained during the whole period of 9 months, before (PTH 590.4 pg/ml) and 9 months after the treatment with cinacalcet (PTH 414.2 pg/ml). In the Table, the PTH, calcium and phosphorus at time 0 (just before starting cinacalcet) and after 9 months of treatment with cinacalcet are shown. Control of secondary hyperparathyroidism (SHPT) in C...

OBJECTIVE The objective of this experiment was to characterize the mRNA expression profile of type IIb sodium-inorganic phosphate cotransporter (NaPi-IIb) and the biochemical values of serum alkaline phosphatase (AKP), calcium, inorganic phosphorus, tibial ash and minerals of broiler chickens with aging. METHODS A total of 56 one-day-old Arbor Acres male broiler chickens were used. Broiler ch...

walnut tree is grown for multiple purposes. indeed, it is economically important and increasing its yield and improving its quality in order to compete in the international markets is one of great importance. to this end, one significant management practice is proper use of suitable fertilizers. zinc and phosphorus are two important elements in the nutrition of walnut. in this study, experiment...
