Abstract:

Phosphorus-31 1D NMR spectra of a stationary powder sample of a phosphole tetramer containing two phosphorus spin pairs have been obtained at 4.7 T and 9.4 T. In order to separate 31P-31P spin-spin coupling from anisotropic chemical shielding, 2D spin-echo NMR spectra have been acquired. Phosphorus-31 CPMAS NMR experiments indicate that the two spin pairs of the tetramer are equivalent and each may be treated as an isolated spin pair. Within a given spin pair, the difference between the isotropic chemical shifts of two directly bonded phosphorus nuclei is 1.7 ppm. As well, they are spin-spin coupled by both the indirect and direct interactions, 1J(31P, 31P) = -362 Hz and RDD = 1.80 kHz, respectively. The principal components and relative orientation of the two phosphorus chemical shielding tensors have been determined using the dipolar-chemical shift technique; however, since the dipolar tensor is axially symmetric, ambiguities in the chemical shielding tensor orientation relative to the molecular framework result. Using ab initio calculations and simulations of the 2D spin-echo spectra, many of these ambiguities have been resolved. The spans and skews of the phosphorus shielding tensors for all four three-coordinate phosphorus nuclei are the same within experimental error, 115 ppm and 0.70, respectively. Combined experimental and theoretical results indicate that the phosphorus shielding tensor orientations are dictated by the local environment. For both shielding tensors, the most shielded component, δ33, is approximately 78° from the P-P bond and in the phosphole ring plane. The relative orientation of the δ33 components is described by a dihedral angle of 82°, similar to the dihedral angle of approximately 76° defining the twist of the phosphole rings about the bridging P-P bond.Key words: solid-state 31P NMR, phosphorus chemical shielding tensors, phosphole tetramer, 31P31P spin pairs, ab initio calculations.

Abstract:

We tested the hypothesis that aging alters physiological regulation of the serum concentration of 1,25-dihydroxyvitamin D [1,25(OH)2D] by inorganic phosphorus. In seven elderly men [age 71 +/- 1 (SE) yr] and 9 young men (29 +/- 2 yr), dietary phosphorus was first normal, then increased and decreased within its normal range. At each intake of phosphorus, serum concentrations of 1,25(OH)2D in the elderly did not differ from those in young men, but fasting and 24-h mean serum concentrations of phosphorus were lower in elderly men. With phosphorus restriction, in each group serum 1,25(OH)2D increased by 47%, and 24-h mean serum phosphorus decreased by 0.6 +/- 0.1 mg/dl. Serum concentrations of 1,25(OH)2D varied inversely with 24-h mean serum phosphorus (R= -0.92, P<0.0001). Thus, in healthy elderly men in whom glomerular filtration rate is normal or near normal, serum concentrations of 1,25(OH)2D increase when dietary phosphorus is restricted; the magnitude of response at steady state is unaffected by aging, but the time course of response is delayed. At any level of serum phosphorus, serum 1,25(OH)2D is lower than that in young men, as reflected by a lower intercept of regression of serum 1,25(OH)2D on 24-h mean phosphorus.

Abstract:

We examined the regulation of 1,25-dihydroxyvitamin D [1,25(OH)2D] synthesis in patients with hypoparathyroidism (n = 5) and pseudohypoparathyroidism (n = 5) by administration of parathyroid extract (PTE) and N6,O2-dibutyryladenosine 3',5'-cyclic monophosphate (dbcAMP) and by phosphorus deprivation with antacids. In response to PTE, patients with hypoparathyroidism increased serum 1,25(OH)2D from 17 +/- 5 to 30 +/- 5 (SD) pg/ml (P less than 0.01). An approximate doubling of the 1,25(OH)2D concentration also occurred following dbcAMP infusion or phosphorus deprivation (serum phosphorus 4.4 +/- 0.5 to 2.6 +/- 1.1, P less than 0.01). Serum phosphorus and 1,25(OH)2D concentrations were inversely correlated (r = -0.73, P less than 0.001). Patients with pseudohypoparathyroidism had negligible responses to PTE with respect to urinary adenosine 3', 5'-cyclic monophosphate excretion, serum phosphorus concentration, or 1,25(OH)2D synthesis. They did show a rise in serum 1,25(OH)2D from 17 +/- 4 to 44 +/- 5 pg/ml (P less than 0.001) in response to dbcAMP infusion. During phosphorus deprivation, serum phosphorus decreased from 4.1 +/- 0.8 to 3.2 +/- 1.2 mg/dl (P less than 0.05), but there was no change in serum 1,25(OH)2D concentration or any correlation between serum phosphorus and 1,25(OH)2D levels. Although reduction in mean serum phosphorus levels was generally not as great in patients with pseudohypoparathyroidism, one such patient attained serum phosphorus of 1.2 mg/dl and still did not increase serum 1,25(OH)2D concentration. In addition to an abnormal parathyroid hormone receptor-adenylate cyclase complex, patients with pseudohypoparathyroidism appear to have an abnormal renal 1 alpha-hydroxylase, which does not respond appropriately to phosphate deprivation.

Abstract:

We tested the hypothesis that in humans, metabolic acidosis can disorder the metabolism of 1,25-dihydroxyvitamin D [1,25(OH)2D] by impairing the capacity for a sustained physiological stimulus to increase renal production of this hormone. Specifically, in seven healthy men in whom restriction of dietary phosphorus had doubled their serum concentration of 1,25(OH)2D, we induced metabolic acidosis of moderate severity with oral NH4Cl, administered for 7 days. With induction of acidosis, the serum concentration of 1,25(OH)2D decreased sharply and remained decreased and near constant throughout the period of acidosis, the decrease amounting to one-half of the increment induced by phosphorus restriction alone. The serum concentration of free 1,25(OH)2D also decreased, since the measured free fraction of 1,25(OH)2D was unaffected by NH4Cl. The decrease in serum 1,25(OH)2D was accounted for by a 16% increase in its metabolic clearance rate and by a 19% decrease in its production rate. Metabolic acidosis induced a modest increase in the concentrations of blood ionized calcium and serum phosphorus. Multiple linear regression analysis revealed that serum levels of 1,25(OH)2D varied inversely and significantly with those of plasma hydrogen ion (R = -0.77, P < 0.001), but not with those of blood ionized calcium or serum phosphorus. These data demonstrate in humans that metabolic acidosis can substantially reverse the increase in serum concentration of 1,25(OH)2D induced by phosphorus restriction. The data provide evidence that acidosis can restrict the increase in renal production and serum concentration of 1,25(OH)2D effected by a sustained physiological stimulus.

Abstract:

To investigate the role of zinc depletion in the response of calcitriol to a single provocative stimulus, we studied vitamin D metabolites, parathyroid hormone (PTH), and mineral balance during phosphorus depletion in animals with different zinc nutritional status. Male Lewis rats (66) were pair fed normal phosphorus (NP), zinc-replete (+) or -deplete (-) diets for 2 wk. Thereafter, one-half of each paired group underwent 1 wk of phosphorus depletion (LP). Zinc-deplete animals had lower plasma zinc, and phosphorus-deplete animals had lower plasma phosphorus concentrations than respective nutritionally replete controls. Plasma calcium, PTH, and 25-hydroxycholecalciferol concentrations were similar in all four groups at end of experiment. Mean plasma 1,25(OH)2D concentration increased 80% from 35 +/- 3 to 63 +/- 9 pg/ml (P less than 0.007) when values were compared before and after phosphorus restriction in zinc-replete animals (LP + group). The 7.9% increase from 35 +/- 4 to 38 +/- 4 pg/ml in 1,25(OH)2D concentration in animals with combined zinc and phosphorus depletion (LP-) was not significant. External calcium balance, however, was maintained in the combined zinc and phosphorus-deplete group. We conclude that zinc depletion limits the increase in plasma 1,25(OH)2D concentration associated with phosphorus depletion. The mechanism is unknown but may involve an effect of zinc on renal 25(OH)D 1-alpha-hydroxylase synthetic activity.

Abstract:

In recent years, photoelectric performances of many low-dimensional metal halide hybrid materials have been researched and utilized in the domain of phosphors, light emitting diodes (LEDs) and photoelectric detection etc. Nevertheless, unlike two-dimensional (2D) ones, one-dimensional (1D) hybrids received less attention to study their structures and optical properties. Herein, we deal with luminous performance and photoluminescence mechanism for an original 1D organic-inorganic lead chloride hybrid C5H14N3PbCl3 which is abbreviated as TMGPbCl3 (TMG+ = 1, 1, 3, 3-tetramethyguanidine cation). According to photoluminescence spectra, its broadband white-light luminescence are dual emissions from organic component TMG+ peaked at 429 nm and self-trapped excitons (STEs) of inorganic metal halide octahedra peaked at 510 nm, respectively and this property make it to be a promising white-light phosphor.

Abstract:

Tri-layer black phosphorus exhibits unique carrier-transport features. Two descriptors have been proposed to analyze the scattering process of electrons and holes and their recombination as well as relaxation dynamics in black phosphorus. This approach is general enough to be applied for the assessment of transport-anisotropy in any 2D (or quasi-2D) materials as well as the critical dependence on the number of layers.

Abstract:

ABSTRACTChemically exfoliated two-dimensional (2D) materials have shown promise in a variety of applications such as thin film transistors and photovoltaic devices. Here, we present a scalable method for preparing black phosphorus membranes via direct liquid-phase exfoliation of the bulk crystal in organic solvents. The black phosphorus sheets are characterized by Raman and Photoluminescence (PL) spectroscopy, and optical microscopy. The properties of these chemically exfoliated black phosphorus was compared to mechanically exfoliated nanomembranes. The liquid-phase exfoliation nonetheless yields the potential for large-area scalability. Our results highlight the important aspects of forming solution dispersions of 2D black phosphorus which can subsequently be the stepping stone for future work on the ink-jet printing of such dispersions over a wide range of substrates.

Abstract:

To determine whether postmaturational aging influences the kinetics of 1,25-dihydroxyvitamin D [1,25(OH)2D] metabolism in the rat, we measured the metabolic clearance (MCR) and production (PR) rates of 1,25(OH)2D in 6-, 12-, 18-, and 24-mo-old Fischer 344 rats using the constant infusion method. Plasma calcium, phosphorus, and parathyroid hormone (PTH), urinary calcium and phosphorus, and glomerular filtration rate (GFR) were also measured. MCR and PR increased 57 and 91%, respectively (when expressed per rat), and 32 and 39%, respectively (when expressed per kg body wt), between 6 and 24 mo of age, with the greatest increase occurring between 18 and 24 mo. The plasma concentration of 1,25(OH)2D remained unchanged. Plasma PTH, when compared with 6-mo-old animals, was significantly elevated at 18 mo (147%) and even higher at 24 mo (240%). GFR (51Cr-labeled EDTA clearance) remained unchanged through 18 mo but tended to be reduced at 24 mo. Plasma phosphorus tended to decrease with age, whereas plasma calcium, urinary calcium, and urinary phosphorus did not differ among the age groups. These data indicate that both clearance and production of 1,25(OH)2D increase with postmaturational aging in the rat. They also suggest that the early age-related rise in plasma PTH is neither a consequence of low plasma calcium nor of renal insufficiency.

Abstract:

The plasma concentration of 1,25-dihydroxyvitamin D [1,25(OH)2D] decreases during skeletal unloading and increases when normal weight bearing is restored. To determine whether these changes in plasma 1,25(OH)2D reflect changes in production, metabolic clearance, or both we measured the kinetics of 1,25(OH)2D metabolism in rats whose skeletons were normally loaded, unloaded, or reloaded after a period of nonweight bearing. Skeletal unloading produced a transient but striking fall in the production (-73%) and plasma concentration (-72%) of 1,25(OH)2D without having a significant effect (< 20%) on metabolic clearance. Skeletal reloading returned production to normal. Bone formation predictably decreased during unloading and returned to normal after return to weight bearing. No consistent changes in blood ionized calcium, plasma immunoreactive parathyroid hormone (irPTH), or plasma phosphorus occurred. These data suggest that the changes in plasma 1,25-(OH)2D associated with changes in skeletal weight bearing primarily reflect changes in 1,25(OH)2D production. The data provide no evidence that the changes in 1,25(OH)2D production are a consequence of changes in blood ionized calcium, plasma irPTH, or phosphorus.

Abstract:

The osteopetrotic (op) rat is a lethal mutation characterized by severe skeletal sclerosis resulting from reduced bone resorption. Although the skeletal manifestations have been studied extensively, little is known about mineral homeostasis in this mutation. This paucity of data prompted us to undertake this study quantitating circulating levels of calcium, phosphorus, 1,25-dihydroxyvitamin D [1,25(OH)2D] and parathyroid hormone (PTH) in op mutants and normal rats between 2 and 8 wk of age. Calcium and phosphorus levels were significantly lower in op mutants at younger ages; both parameters normalized by 6 wk. Serum levels of 1,25(OH)2D were markedly elevated in op rats at all ages and showed no signs of normalization. Serum PTH levels were also elevated at most ages, with the greatest increase occurring when op mutants were severely hypocalcemic. These results demonstrate that, in op mutants, changes in circulating PTH and calcium levels were interdependent; however, levels of 1,25(OH)2D did not change despite normalization of serum calcium and phosphorus. The latter deserves further investigation and supports the hypothesis of a localized (skeletal) resistance to 1,25(OH)2D.

Abstract:

One hundred years after its first successful synthesis in the bulk form in 1914, black phosphorus (black P) was recently rediscovered from the perspective of a 2D layered material, attracting tremendous interest from condensed matter physicists, chemists, semiconductor device engineers, and material scientists. Similar to graphite and transition metal dichalcogenides (TMDs), black P has a layered structure but with a unique puckered single-layer geometry. Because the direct electronic band gap of thin film black P can be varied from 0.3 eV to around 2 eV, depending on its film thickness, and because of its high carrier mobility and anisotropic in-plane properties, black P is promising for novel applications in nanoelectronics and nanophotonics different from graphene and TMDs. Black P as a nanomaterial has already attracted much attention from researchers within the past year. Here, we offer our opinions on this emerging material with the goal of motivating and inspiring fellow researchers in the 2D materials community and the broad readership of PNAS to discuss and contribute to this exciting new field. We also give our perspectives on future 2D and thin film black P research directions, aiming to assist researchers coming from a variety of disciplines who are desirous of working in this exciting research field.

Abstract:

AbstractIn this review, we survey the recent advances in nonlinear optics and the applications of two-dimensional (2D) materials. We briefly cover the key developments pertaining to research in the nonlinear optics of graphene, the quintessential 2D material. Subsequently, we discuss the linear and nonlinear optical properties of several other 2D layered materials, including transition metal chalcogenides, black phosphorus, hexagonal boron nitride, perovskites, and topological insulators, as well as the recent progress in hybrid nanostructures containing 2D materials, such as composites with dyes, plasmonic particles, 2D crystals, and silicon integrated structures. Finally, we highlight a few representative current applications of 2D materials to photonic and optoelectronic devices.

Abstract:

The prospects of using nanostructured black phosphorus for the development of humidity sensors are considered. It was shown that black phosphorus has a set of parameters that distinguish it from other two-dimensional (2D) materials such as graphene, silicone, and dichalcogenides. At the same time, an analysis of shortcomings, limiting the use of black phosphorus as a humidity sensitive material in devices aimed for market of humidity sensors, was also conducted.

Abstract:

Black phosphorus (BP), a single elemental two-dimensional (2D) material with a sizable band gap, meets several critical material requirements in the development of future nanoelectronic applications. This work reports the ambipolar characteristics of few-layer BP, induced using 2D transparent hexagonal boron nitride (h-BN) capping. The 2D h-BN capping have several advantages over conventional Al2O3 capping in flexible and transparent 2D device applications. The h-BN capping technique was used to achieve an electron mobility in the BP devices of 73 cm2V−1s−1, thereby demonstrating n-type behavior. The ambipolar BP devices exhibited ultrafast photodetector behavior with a very high photoresponsivity of 1980 mA/W over the ultraviolet (UV), visible, and infrared (IR) spectral ranges. The h-BN capping process offers a feasible approach to fabricating n-type behavior BP semiconductors and high photoresponse BP photodetectors.

Abstract:

AbstractTwo-dimensional (2D) mono-elemental materials (Xenes) show remarkable potential in the fields of fundamental science and technology, have been regarded as a wide range of building blocks for electronic technologies due to their unique chemical, physical, electrical, and optical properties. Here, 2D tellurene/black phosphorus (Te/BP) heterojunctions are successfully fabricated through liquid-phase exfoliation (LPE) method. Their nonlinear optical absorption properties at 1.0, 2.0, and 2.8 μm have been studied by an open-aperture Z-scan method. The results revealed the excellent broadband saturable absorption responses of the prepared BP/Te heterojunctions, which are further confirmed by using them as saturable absorbers (SAs) for passively Q-switched all-solid-state lasers operating at 1.0, 2.0, and 2.8 μm, respectively. In particular, 1.04 μm continuous-wave (CW) mode-locked lasers with a pulse width of 404 fs is realized for the first time, to our best knowledge. Our work indicates that 2D Xenes especially 2D Xenes based heterojunctions have great potential in the fields of pulsed laser generation/modulation and other optoelectronic and photonic devices.

Abstract:

In the present study, we have evaluated the role of calcium and phosphorus concentrations in serum on the mineralization of bone in the absence of vitamin D. This was accomplished by feeding mother rats and subsequently their pups vitamin D-deficient diets varying in calcium, phosphorus, and lactose content. After 5-7 wk on these diets, serum concentrations of 25-hydroxyvitamin D [25(OH)D] and 1,25-hydroxyvitamin D [1,25(OH)2D] were undetectable. Rats fed a vitamin D-deficient diet containing 0.44% calcium and 0.3% phosphorus showed a serum calcium of 4.9-5.9 mg/dl and a serum phosphorus of 7.3-8.2 mg/dl; rickets (wide epiphysial plates) had developed as well as osteomalacia (wide osteoid seams). Rats maintained on a vitamin D-deficient diet containing 3% calcium and 0.65% phosphorus had normal serum calcium, low serum phosphorus, and severe rickets, but osteomalacia was not seen. Rats fed a diet containing 20% lactose, 4% calcium, and 1% phosphorus showed normal serum calcium, somewhat low serum phosphorus, normal serum PTH, normal width of the epiphysial plate, normal volume density of trabecular bone, and normal volume density of osteoid seams. These data confirm the findings of others, using a different experimental model, that serum calcium and phosphorus concentrations are the determining factors in mineralization defects and not the absence of 25(OH)D or 1,25(OH)2D. In these rats thyroparathyroidectomy is well tolerated, which makes for an ideal model for the study of the effects of calcium-regulating hormones on bone histology, cytology, and biochemistry.
