Embodiments of the present invention include systems and methods for generating a curvature compensated bandgap voltage reference. In an embodiment, a curvature compensated bandgap reference voltage is achieved by injecting a temperature dependent current at different points in the bandgap reference voltage circuit. In an embodiment, the temperature dependent current is injected in the proportional to absolute temperature (PTAT) and complementary to absolute temperature (CTAT) current generation block of the bandgap circuit. Alternatively, or additionally, the temperature dependent current is injected at the output stage of the bandgap circuit. In an embodiment, the temperature dependent current is a linear piecewise continuous function of temperature. In another embodiment, the temperature dependent current has opposite dependence on temperature to that of the bandgap voltage reference before curvature compensation.
Phylogenetically diverse anammox bacteria have been detected in most of anoxic natural and engineered ecosystems and thus regarded as key players in the global nitrogen cycle. However, ecological niche differentiation of anammox bacteria remains unresolved despite its ecological and practical importance. In this study, the microbial competitions for a common substrate (nitrite) among three anammox species (i.e. "Candidatus Brocadia sinica", "Candidatus Jettenia caeni" and "Candidatus Kuenenia stuttgartiensis") were systematically investigated in nitrite-limited gel-immobilized column reactors (GICR) and membrane bioreactors (MBRs) under different nitrogen loading rates (NLRs). 16 S rRNA gene-based population dynamics revealed that "Ca. J. caeni" could proliferate only at low NLRs, whereas "Ca. B. sinica" outcompeted other two species at higher NLRs in both types of reactors. Furthermore, FISH analysis revealed that "Ca. J. caeni" was mainly present as spherical microclusters at the inner part ...
Metal halide perovskites such as methylammonium lead iodide (CH3NH3PbI3) are generating great excitement due to their outstanding optoelectronic properties, which lend them to application in high-efficiency solar cells and light-emission devices. However, there is currently debate over what drives the second-order electron-hole recombination in these materials. Here, we propose that the bandgap in CH3NH3PbI3 has a direct-indirect character. Time-resolved photo-conductance measurements show that generation of free mobile charges is maximized for excitation energies just above the indirect bandgap. Furthermore, we find that second-order electron-hole recombination of photo-excited charges is retarded at lower temperature. These observations are consistent with a slow phonon-assisted recombination pathway via the indirect bandgap. Interestingly, in the low-temperature orthorhombic phase, fast quenching of mobile charges occurs independent of the temperature and photon excitation energy. Our work ...

Anaerobic ammonium-oxidizing (anammox) bacteria perform an important step in the global nitrogen cycle: oxidizing ammonium and reducing nitrite to form dinitrogen gas in the absence of oxygen. Anammox bacteria from the Planctomycetes phylum have been identified in a variety of natural environments but their role in groundwater ammonium oxidation has been unclear. Recent isotope studies have suggested that anammox bacteria are likely active in ammonium attenuation at contaminated groundwater sites; however, only limited biomarker-based data confirmed their presence prior to this study. I used complimentary molecular and isotope-based methods to assess the communities of anammox performing organisms at three ammonium contaminated groundwater sites in Canada: quantitative real-time PCR (qPCR), denaturing gradient gel electrophoresis (DGGE), DNA sequencing of 16S rRNA genes (with both Sanger and Illumina technologies), and ¹⁵N-tracer incubations. DNA sequencing and qPCR results demonstrated that ...

We here report a simple and efficient method to grow single-layer bismuth nanoparticles (BiNPs) with various sizes on glass substrates. Optimal conditions were found to be 200°C and 0.12 W/cm2 at a growth rate of 6 Å/s, with the deposition time around 40 s. Scanning electron microscope (SEM) images were used to calculate the particle size distribution statistics, and high-resolution X-ray diffraction (XRD) patterns were used to examine the chemical interactions between BiNPs and the substrates. By measuring the transmission spectra within the range of 300 to 1,000 nm, we found that the optical bandgap can be modulated from 0.45 to 2.63 eV by controlling the size of these BiNPs. These interesting discoveries offer an insight to explore the dynamic nature of nanoparticles.
Surface Bloch modes induced on three-dimensional dielectric photonic crystals with a complete photonic bandgap are evanescently decaying states at surfaces and have large field overlap with low-index media, resulting in narrow spectrum linewidth and simultaneously a large resonance shift due to a perturbation of the refractive index in the background media. Surface Bloch resonance states are analyzed for ...
An effective description is developed for a metalodielectric photonic bandgap (PBG) material far beyond the quasi-static limit of traditional effective-medium theories. An analytic approach, recently presented by the authors, is further advanced to provide the complete effective permittivity and permeability functions. Reflection and transmission coefficients are presented for both TM and TE oblique plane-wave incidence, based on the determination of the equivalent impedance for each lattice plane in the crystal and the transfer-matrix method for reconstructing the effect of successive lattice planes. An analysis of the semi-infinite and slab observables yields the anisotropic effective refractive index, effective permittivity, and effective permeability, thus completing the macroscopic description of the interaction of electromagnetic waves with the medium. Among the novel aspects of the analysis is the equivalence of our PBG system with a physically dispersive system at ultraviolet frequencies ...
An n-type layer of the opposite conduction type composed of n-GaN is formed between a light emitting layer and a p-type cladding layer composed of p-AlGaN. The bandgap of the n-type layer of the opposite conduction type is larger than the bandgap of the light emitting layer and is smaller than the bandgap of the p-type cladding layer.
Anammox﻽: Traditionally, all nitrification was thought to be carried out under aerobic conditions, but recently a new type of ammonia oxidation occurring under anoxic conditions was discovered (Strous et al. 1999). Anammox (anaerobic ammonia oxidation) is carried out by prokaryotes belonging to the Planctomycetes phylum of Bacteria. The first described anammox bacterium was Brocadia anammoxidans. Anammox bacteria oxidize ammonia by using nitrite as the electron acceptor to produce gaseous nitrogen (Figure 6). Anammox bacteria were first discovered in anoxic bioreactors of wasterwater treatment plants but have since been found in a variety of aquatic systems, including low-oxygen zones of the ocean, coastal and estuarine sediments, mangroves, and freshwater lakes. In some areas of the ocean, the anammox process is considered to be responsible for a significant loss of nitrogen (Kuypers et al. 2005). However, Ward et al. (2009) argue that denitrification rather than anammox is responsible for ...

Objectives: This study was undertaken to examine the influence of partial demineralization of xenogenous dentin on bone formation in an osteoconductive environment. Materials and methods: Sixty dentin blocks, 2-3 mm thick and 4 mm in diameter, were prepared from developing teeth of young pigs. Forty blocks were demineralized in 24% ethylenediaminetetraacetic acid (pH 7.0) for 1, 2, 6 or 12 h. Forty adult rats divided into eight groups with five rats in each group were used. A sagittal midcranial incision was made from the occipital to the frontal region. Through a subperiostal dissection, a pocket was created on each side of the skull. One demineralized block was placed on one side, and a non-demineralized block was placed on the contralateral side, or the pocket was left empty as controls. Thus, eight experimental groups with five rats in each were formed. Results: Resorption increased significantly with increasing degree of demineralization while bone formation increased significantly with ...
Because the TA signal results from combined Pauli blocking and bandgap renormalization effects (44, 49), there are two possible reasons for the increased TA intensities at strong-coupling locations: (i) The absorption above the bandgap is increased by the interlayer CT transitions and an increased TA intensity is due to Pauli blocking and (ii) photoexcitation of CT transitions leads to larger bandgap renormalization effects than excitons. Note that transient bandgap renormalization observed here is due to further modifications of the exciton energy upon photoexcitation beyond the static effect (49, 50). To directly measure the interlayer coupling-dependent absorption at 3.14 eV, we imaged correlated reflection and transmission of 1L-WS2/G on a transparent sapphire substrate (fig. S9). The linear absorption is deduced using approaches described in Materials and Methods. The linear absorption and correlated TAM image are shown in Fig. 4 (C and D). Both linear absorption and transient absorption ...

Silicon technologyhas been seekingfor a monolithic solution for a chip where data processing and data communication is performed in the CMOS part and the photonic component, respectively. Traditionally, silicon has been widely considered for electronic applications but not for photonic applications due to its indirect bandgap nature. However, band structure engineering and manipulation through alloying Si with Ge and Sn has opened new possibilities. Theoretical calculations show that it is possible to achieve direct transitions from Ge ifit is alloyed with Sn. Therefore, a GeSn system is a choice to get a direct bandgap. Extending to ternary GeSnSi and quaternary GeSnSiCstructures grown on Si wafers not only makes the bandgap engineering possible but also allowsgrowing lattice matched systems with different strain and bandgaps located in the infrared region. Different heterostructures can be designed and fabricated for detecting lightas photonic sensing oremitting the light as lasers. Alloying ...
UV light.. Major efforts have been made to improve titanias absorption of visible light or develop visible-light sensitive materials in general.. Methods used for titania, including metal ion doping, carbon doping, nitrogen doping and hydrogenation usually require stringent conditions to obtain the modified TiO2 such as elevated temperature or high pressure.. In their innovative paper published in Chemical Communications, a Royal Society of Chemistry journal, the researchers observed that when TiO2 particles are mixed with graphene quantum dots, the resulting composite absorbs visible light by a quantum-confined bandgap narrowing mechanism.. "We were really excited to discover this: when two UV absorbing materials, namely TiO2 and graphene quantum dots, were mixed together, they started to absorb in the visible range, more significantly, the bandgap can be tuned by the size of graphene quantum dots," says Dr Li.. "We named the phenomenon quantum-confined bandgap narrowing and this mechanism ...

A semiconductive conjugated copolymer comprises at least two chemically different monomer units which, when existing in their individual homopolymer forms, have different semiconductor bandgaps. The proportion of said at least two chemically different monomer units in the copolymer is selected to control the semiconductor bandgap of the copolymer so as to control the optical properties of the copolymer. The copolymer is formed in a manner enabling it to be laid down as a film without substantially affecting the luminescent characteristics of the copolymer and is stable at operational temperature. The semiconductor bandgap may be spatially modulated so as to increase the quantum efficiency of the copolymer when excited to luminesce, to select the wavelength of radiation emitted during luminescence or to select the refractive index of the copolymer.

In 2006 the German government introduced the "new start-up subsidy" ("Gründungszuschuss") to support unemployed individuals to become self-employed. The implementation of this program replaced two earlier programs, i.e., the bridging allowance ("Überbrückungsgeld") and the start-up subsidy ("Existenzgründungs-zuschuss"). Evaluations of the latter two programs within the Hartz-Evaluation and the IZA research project Long-Run Effects of Start-Up Subsidies (see below) showed that they were quite successful. The current project aims at evaluating the new start-up subsidy and is therefore a consistent extension of the research on start-up subsidies in Germany. We adopt a holistic evaluation approach, comparing the labor market outcomes of subsidized business founders and a control group of other unemployed individuals on the one hand, and the performance of subsidized businesses to unsubsidized start-ups on the other. Furthermore, we survey supported entrepreneurs right after they are starting ...
Devices and techniques for integrating a silicon superlattice optical modulator on a silicon substrate with other circuit elements. The superlattice structure is designed to convert the indirect bandgap structure of silicon into a direct bandgap structure to achieve more efficient optical absorption. The modulator can be fabricated based on a structure of a circuit element by using standard fabrication processes for silicon integrated circuits such as metal oxide semiconductor processing.
The present invention provides a heterojunction photodiode which includes a pn or Schottky-barrier junction formed in a first material region having a bandgap energy E.sub.g1. When reverse-biased, the junction creates a depletion region which expands towards a second material region having a bandgap energy E.sub.g2 which is less than E.sub.g1. This facilitates signal photocurrent generated in the second region to flow efficiently through the junction in the first region while minimizing the process-related dark currents and associated noise due to near junction defects and imperfect surfaces which typically reduce photodiode device performance. The heterojunction photodiode can be included in an imaging system which includes an array of junctions to form an imager.

Due to the strong quantum confinement effect, few-layer γ-InSe exhibits a layer-dependent bandgap, spanning the visible and near infrared regions, and thus recently draws tremendous attention. As a two-dimensional material, the mechanical flexibility provides an additional tuning knob for the electronic structures. Here, for the first time, we engineer the band structures of few-layer and bulk-like InSe by uniaxial tensile strain, and observe salient shift of photoluminescence (PL) peaks. The shift rate of the optical gap is approximately 90-100 meV per 1% strain for 4- to 8-layer samples, which is much larger than that for the widely studied MoS2 monolayer ...

The nitrogen removal pathways in anaerobic ammonium oxidation (anammox) process where anaerobic ammonium-oxidizing bacteria and denitrifying heterotrophs convert ammonium and nitrite directly to dinitrogen gas under anoxic conditions were investigated using a mathematical model. The Activated Sludge Model No. 1 (ASM1) was modified with two step denitrification and one-step anaerobic ammonia oxidation. A one dimensional granular biofilm model was implemented in Aquasim 2.1v (EAWAG, Switzerland) in order to describe a series of batch processes operated in a bioreactor treating synthetic wastewater. A sophisticated statistical method was used for parameter estimation. The model was not sensitive with respect to the detachment velocity in the biofilm matrix as well as the porosity coefficients of dissolved state variables. The final results showed a satisfactory goodness of fitness representing Pearson correlation coefficients of 0.96, 0.98 and 0.81 for modeled and measured concentrations of NH4-N, NO2-N
12 Apr 2017. NUS chemists have demonstrated an electrical field-controlled giant Stark effect in black phosphorus for potential applications in advanced electro-optic modulators and photodetector devices.. The bandgap is a material property that determines electrical conductivity. Solids with large bandgaps are generally insulators as they do not conduct electricity. Those with smaller bandgaps are semiconductors. A team of NUS researchers have demonstrated that the bandgap of black phosphorus (BP) changes in the presence of an electric field. By controlling the electric field strength, they have shown that the bandgap of BP can be adjusted to a desired level. This means that by changing the electric field, the material can be made to either conduct or not to conduct electricity. The findings can potentially be used for advanced optoelectronic devices operating beyond the visible light spectrum.. When a few atomic layers of BP are exposed to an electric field, a physical phenomenon known as the ...

This study investigated the diversity, community composition, and abundance of anaerobic ammonium oxidation (anammox) bacteria along the altitudinal gradient in Qinghai-Tibet Plateau. Two types of soil samples (wetland and dryland soils, n = 123) were collected from 641 m to 5,033 m altitudes. Polymerase chain reaction (PCR) screening showed that anammox were not widespread, and were only detected in 9 sampling sites of the 50 sites tested by amplifying the 16S rRNA genes. Then, only samples collected from Linzhi (2,715 m), Rikaze (4,030 m), and Naqu (5,011 m), which were positive for the presence of anammox, were further processed to explore the biogeography of anammox bacteria in Qinghai-Tibet Plateau ...

Graphene is a zero-gap semiconductor, because its conduction and valence bands meet at the Dirac points, which are six locations in momentum space, on the edge of the Brillouin zone, divided into two non-equivalent sets of three points. The two sets are labeled K and K. The sets give graphene a valley degeneracy of gv = 2. By contrast, for traditional semiconductors the primary point of interest is generally Γ, where momentum is zero. Four electronic properties separate it from other condensed matter systems. However, if the in-plane direction is confined, in which case it is referred to as a nanoribbon, its electronic structure is different. If it is "zig-zag", the bandgap is zero. If it is "armchair", the bandgap is non-zero (see figure). Electrons propagating through graphenes honeycomb lattice effectively lose their mass, producing quasi-particles that are described by a 2D analogue of the Dirac equation rather than the Schrödinger equation for spin-​1⁄2 particles. When atoms are ...
Instead of getting graphene to behave like traditional silicon transistors, researchers propose harnessing the non-Boolean logic that graphene devices naturally exhibit.

High-mobility perovskite BaSnO 3 films are of significant interest as newwide bandgap semiconductors for power electronics, transparent conductors, and as high mobility channels for epitaxial integration with functional perovskites. Despite promising results for single crystals, high-mobility BaSnO 3 films have been challenging to grow. Here, we demonstrate a modified oxide molecular beam epitaxy (MBE) approach, which supplies pre-oxidized SnO x. This technique addresses issues in the MBE of ternary stannates related to volatile SnO formation and enables growth of epitaxial, stoichiometric BaSnO 3. We demonstrate room temperature electron mobilities of 150 cm 2 V -1 s -1 in films grown on PrScO 3. Lastly, the results open up a wide range of opportunities for future electronic devices. ...

It is claimed that the addition of biochar to soil improves C sequestration, soil fertility and plant growth, especially when combined with organic fertilizers such as compost. However, little is known about agricultural effects of small amounts of composted biochar. This greenhouse study was carried out to examine effects of co-composted biochar on oat (Avena sativa L.) yield in both sandy and loamy soil. The aim of this study was to test whether biochar effects can be observed at very low biochar concentrations. To test a variety of application amounts below 3 Mg biochar ha−1, we co-composted five different biochar concentrations (0, 3, 5, 10 kg Mg−1 compost). The biochar-containing compost was applied at five application rates (10, 50, 100, 150, 250 Mg ha−1 20 cm−1). Effects of compost addition on plant growth, Total Organic Carbon, Ntot, pH and soluble nutrients outweighed the effects of the minimal biochar amounts in the composted substrates so that a no effect level of biochar of at
The work, being led by Prof Colin Stanley at the universitys department of Electronics and Electrical Engineering, centres around the use of quantum dot crystals to develop photovoltaic (PV) cells known as Intermediate Band Solar Cells (IBSCs).. In PV cells a proportion of the solar spectrum is unused because the semiconductor from which the cell is made is transparent to photons with energies less than its bandgap. A higher proportion of the solar spectrum can be absorbed by using a semiconductor with a small bandgap.. A cell made from this material will produce a lot of current, but at a low voltage, explained Stanley. Conversely, if a wide bandgap semiconductor is employed, the output voltage will be high but the current will be low.. In an attempt to address these trade-offs, the team at Glasgow has been working on a new type of PV based on III-V semiconductor quantum dots, which has the potential to outperform existing types of multi-junction III-VPVs.. According to Stanley, the IBSC ...

A by-product of biofuel manufacture can power microbial fuel cells to generate electricity cheaply and efficiently, according to scientists presenting their work at the Society for General Microbiologys Autumn Conference. The work could help develop self-powered devices that would depollute waste water and be used to survey weather in extreme environments.. Distillers Dried Grain with Solubles (DDGS) is a waste product from bioethanol production that is commonly used as a low-cost animal feed. Researchers from the University of Surrey incorporated DDGS together with bacteria-inoculated sludge from a waste water treatment plant in their microbial fuel cell. The design of the fuel cell meant that the bacteria, which used the DDGS for growth, were physically separated from their oxygen supply. This meant that the bacteria were forced into sending electrons around a circuit leading to a supply of oxygen. By tapping into this electron flow, electricity could be generated from the waste..

Little or no urine is made, even though the kidney itself is working.. When nitrogen waste products, such as creatinine and urea, build up in the body, the condition is called azotemia. These waste products act as poisons when they build up. They damage tissues and reduce the ability of the organs to function..
