description: Losses due to shading occur in even the most ideal PV systems owed to a range of avoidable and
unavoidable sources. Of the available shade avoidance solutions, Global Maximum Power Point Tracking (GMPPT)
and high degree diode bypassing are cost effective, complementary and implementable options available today.
GMPPT algorithms are a group of emerging tracking methods which can be implemented across a broad range of
inverter and charge controlling electronics. By differentiating local maxima from the global maximum power point,
GMPPT can avoid errors in chosen operating conditions. High degree diode bypassing, implemented through Work-
Smart™ technology, enables an increased accuracy in isolating partially shaded cells and avoids large secondary
losses in unaffected cells. This paper will present an analysis of a traditional MPPT and an operational GMPPT
algorithm, examining their interaction with modules of low degree diode bypassing as compared with Work-Smart™
technology’s high degree diode bypassing. We find that unnecessary shading losses can be nearly fully eliminated in
systems implementing GMPPT in combination with Work-Smart™ technology.

description: In this work, we present a simple approach for the transfer of the passivated emitter and rear cell
(PERC) device structure from laboratory status to industrial manufacturing. The approach uses a thin layer of
thermally grown oxide for the simultaneous passivation of both front emitter and rear surface. This Thermal Oxide
Passivated All Sides (TOPAS) structure represents an industrially feasible design of the PERC concept, as we
circumvent costly masking steps. Instead side selective, wet-chemical etching allows the realisation of a structure
with a textured and diffused front surface and a plain, non diffused rear surface. The implementation of a selective
emitter by laser-doping from a phosphosilicate glass source enables the use of screen-printed Ag front contacts. With
the presented approach, on 180 μm thick boron-doped Czochralski (Cz) grown silicon wafers of base resistivity
1.6 Ωcm we achieve efficiencies of up to 18.9 % (initial) and a high open-circuit voltage of 641 mV (stable). The
antireflection coating stack of a thin thermal oxide and a SiNX layer on top yields a lower emitter dark saturation
current density than a single SiNX layer. Furthermore, we present similar values for the specific cost of the standard
Al-BSF solar cell process and the presented TOPAS process.

description: Dye sensitized solar cells (DSSC) have gained much interest in recent years due to its low cost,
improved conversion efficiency and practical application methods. Most of the measurements of the efficiency of
dye sensitized solar cells are made in liquid electrolyte (I-/I3
- redox couple). Because, liquid electrolyte allows
high electron mass transfer between dye and counter electrode and this also contributes to the efficiency. On the
other hand, liquid electrolytes cause several problems to the system which are volatility of electrolyte, electrode
corrosion, difficulties in sealing and short time stability of the device. Recently, some work has been done to
replace liquid electrolytes with some solid systems. Solvent free ionic liquid electrolyte is shown to be a good
choice for DSSC applications due to thermal stability, non-flammability, high ionic conductivity, negligible
vapour pressure and non-toxicity as solid state. However, solid structure decreases the electron transfer rate and
diffusion length; in other words, with this type of electrolyte, efficiency decreases considerably. This decrease
can be compensated by 4 different mechanisms. These are bifacial design, additional SiO2 layer, thickness
optimization of the semiconductor layer and using additional chemicals. In this work, TiO2 will be used as
semiconductor and it will be synthesized using related procedures as porous structures. 1-propyl 3-
methylimidazolium iodide and 1-ethyl 3- methylimidazolium tetracyanoborate (PMII//(EMIB(CN)4)) electrolyte
will be used as ionic liquid electrolyte.

description: Microwave and DC plasma jets as well as the combination of both are powerful thin film deposition
technologies which offer the potential of high growing rates beyond 100 nm/s. In order to offer sufficient Si material
for large area and high rate deposition, the Si raw material is fed as powder into the plasma chamber. Then the Si
powder is consequently transferred by high energetic plasma interaction from its solid to its molten state and finally
into its atomic gas phase and furthermore ionized plasma state. The application of such high power plasma
technologies with integrated Si powder feeding results in deposited (a-Si) and (μc-Si) layers on glass and Si-wafer
substrates with experimentally proofed growing rates of up to 25-100 nm/s across an area of 0.2 m x 0.2 m.

description: Call a noncommutative rational function $r$ regular if it has no singularities, i.e., $r(X)$ is defined for all tuples of self-adjoint matrices $X$. In this article regular noncommutative rational functions $r$ are characterized via the properties of their (minimal size) linear systems realizations $r=c^* L^{-1}b$. It is shown that $r$ is regular if and only if $L=A_0+\sum_jA_j x_j$ is privileged. Roughly speaking, a linear pencil $L$ is privileged if, after a finite sequence of basis changes and restrictions, the real part of $A_0$ is positive definite and the other $A_j$ are skew-adjoint. The second main result is a solution to a noncommutative version of Hilbert's 17th problem: a positive regular noncommutative rational function is a sum of squares.

description: The optical constants of different conjugated polymers and CdSe nanoparticles (NP) are analysed using
spectroscopic ellipsometry. These results are used to model their blends by effective medium approximation (EMA)
with a strongly reduced number of parameters. As a result of these models, the volume ratio of the blended
components and gradients of the composition along the film thickness are found. The gradients are confirmed by
high-resolution transmission electron microscopy. In combination with the mass ratio of the blend the determined
volume ratio leads to the mass density of the NP species. This allows for the analysis of the capping ligand on the NP
surface in the sub-nanometer range.

description: The first rule of business is “know your customer”. This essay focuses on the user’s perspective: what do tutors need to make OBL an attractive proposition? It dissects three customer needs: the need for engagement, logistical concerns, and pedagogical dimensions. Several suggestions are offered regarding each type of need. The overall goal is to encourage the structuring of OBL promotions and provision in ways that integrate easily into the working life of tutors. This is the key to successful programme development.

description: By coupling with a qubit, we demonstrate that qubit decoherence can unambiguously detect the occurrence of ground-state degeneracy in many-body systems. We first demonstrate universality using the two-band model. Consequently, several exemplifications, focused on topological condensed matter systems in one, two, and three dimensions, are presented to validate our proposal. The key point is that qubit decoherence varies significantly when energy bands touch each other at the Fermi surface. In addition, it can partially reflect the degeneracy inside the band. This feature implies that qubit decoherence can be used for reliable diagnosis of ground-state degeneracy.

It often happens that its development and maintenance requires too much resources, especially when the data model changes. Swing Dynamic GUI library overcomes this problem and simplifies both development and maintenance of user interface. This module provides a set of ready to use mechanisms, which allows rendering and validating form fields, managing form layouts, as well as generating data-driven tables. Thanks to reflection and Bean Validation mechanisms this library handles all the Java Swing components configuration, components data binding as well as input validation allowing to generate fully functional user interfaces in fraction of time and effort by using dedicated annotations and few lines of code.

description: Dye sensitized solar cells (DSSC) employing nanoparticle based mesoporous anodes have been
extensively studied in recent years. Although best efficiencies are obtained with cells made from titanium dioxide
(TiO2), application of new metal oxides and anode structures are major subjects of research. Tin dioxide (SnO2) is a
promising candidate presenting high electron mobilities and electronic conductivity upon doping with elements like
fluorine. In this work, as a production technique, homogeneously precipitated tin dioxide nanoparticles have been
doped with fluorine under hydrothermal conditions resulting in resistivies around 770 ohm.cm. Dye sensitized solar
cells have been constructed by screen printing from bare fluorine doped SnO2 nanoparticles, commercial TiO2
nanoparticles and core shell type mesoporous anodes employing TiO2 as shell material. TiO2 coating has been
achieved from hydrolysis of aqueous solutions of ammonium hexafluorotitanate and titanium tetrachloride as
precursor materials. Upon surface treatment of tin dioxide, photovoltage, photocurrent and fill factor of cells have
been extensively improved as a result of suppression of recombination reactions. Best results were obtained from
titanium tetrachloride treated cells giving current densities of 22.8 mA/cm2, higher than that of TiO2, however
photovoltage and fill factor are still lower than TiO2, giving efficiencies of 4.61% and 6.54%, respectively.

description: Reliability is estimated within the automotive industry by established methods. Transferring this
experience to the solar industry enables one to estimate the reliability of PV modules. However, currently PV
modules are certified by third-party test laboratories according to standard test sequences which do not necessarily
provide full evidence that the product performs adequately within its lifetime of 25 years.
This work presents a method for defining tests for PV modules, exemplarily shown for one failure mode which is
thermo-mechanical fatigue of solder joints used in PV modules. The temperature changes causing damage were
measured on PV modules located in Germany. The measured data was classified into load spectrums (number of
temperature cycles and the particular distance between maximum and minimum temperature).
The acceleration factor and ageing law of the particular failure mechanism are dependent on the technology and
material which is used. This data was obtained from published data for solder joints of electronic devices.
Ageing law, acceleration factor as well as load spectrum can be used to compute the stress and the time of the tests.
Using this approach within tests, samples are stressed corresponding to the field load. Therefore, the tests are able to
represent the lifetime of PV modules. The failure-mode based approach introduced herein represents a method to
validate the reliability of a design. Moreover, it highlights that current standard test sequences may either over- or
undervalue relevant effects. In the latter case, standard test sequences may not cover all failure modes and may
therefore ignore field-relevant problems.

description: In the photovoltaic industry light trapping by front and rear side texturing is an increasing important
issue with decreasing wafer thickness down to 100 μm for saving costs. In this study the impact of backside texturing
by application of the Linear Microwave Plasma (LMP) technique in a SF6/O2 plasma chemistry has been investigated.
The textured surfaces have been characterized in terms of statistical roughness parameters and the scatter angle
distribution function using atomic force microscopy (AFM). Moreover, the reflection and transmission have been
determined using an integrating sphere setup. In addition reflection, transmission and absorption have been
investigated for the dielectric passivation system which consists of a-SiNx:H front side passivation and AlOx-SiOx
rear surface passivation as well as for the multiple layer system which consists of the dielectric passivation system
including an aluminium rear side metallization corresponding to the complete solar cell.

description: Due to the ever expanding availability of new materials for PV applications, comparison studies must
be performed to demonstrate the benefits of varying materials. In photovoltaic applications backsheets are exposed to
ultraviolet light, heat, and humidity which break down the chemical bonds in average polymeric materials causing
discoloration and reduced mechanical strength and reduced resistance to humidity which combine to destroy a
module’s capability to produce power. In this paper we will discuss the weatherability of the various backsheet
materials currently on the market. ZEFFLE®, a Daikin trademarked tetrafluoro-ethylene copolymer, coated
backsheet construction will be compared with current backsheet constructions utilizing laminated PVF films, PVDF
backsheets, and non-fluorinated laminated backsheet alternatives such as PET to demonstrate the variation in
weatherability and performance of each material.
Samples were exposed to xenon arc accelerated weathering testing per ASTM-G155 and 85/85 damp heat
testing. We will discuss several common test methods to approximate the real world performance of these materials
as backsheets over time. After reviewing the results it can be seen that ZEFFLE®’s performance as a coating is
similar to other fluorine based film products. This paper also demonstrates the benefit of fluorinated backsheets when
compared to non-fluorinated backsheets.

designs of the commercially available turnkey line “FlexLine Plus” are described: 1) a selective emitter including
laser ablation of a “diffusion inhibiting” oxide layer with a subsequent single diffusion through it and 2) a single
diffusion step selective emitter process performed by “direct laser diffusion”. Best mean values of up to 18.6 % on
monocrystalline Cz and 17.1 % on multicrystalline material processed with industrially applicable equipment and
high throughput were achieved. The additional process steps were successfully integrated into the existing standard
process.

description: In this paper we present a new wet chemical texturing process (Random Honeycomb Texturing)
suitable for thin silicon solar cells manufacturing. The benefits of proposed texturing method are: reduced front
surface reflectivity; chemical polishing of the rear surface; no defects etch; texturing is independent on saw
damage; both sides of the wafer are treated in the same step; relative simplicity of process. The key point of
process is the use of blistering of hydrogenated dielectric layer to create the local opening in the etch mask.
Texturing process was tested on industrial type high throughput equipment.

description: Inspired by the methods of Voisin, the first two authors recently proved that one could read off the gonality of a curve C from the syzygies of its ideal in any one embedding of sufficiently large degree. This was deduced from from a vanishing theorem for the asymptotic syzygies associated to an arbitrary line bundle B on C. The present paper extends this vanishing theorem to a smooth projective variety X of arbitrary dimension. Specifically, given a line bundle B on X, we prove that if B is p-jet very ample (i.e. the sections of B separate jets of total weight p+1) then the weight one Koszul cohomology group K_{p,1}(X, B; L) vanishes for all sufficiently positive L. In the other direction, we show that if there is a reduced cycle of length p+1 that fails to impose independent conditions on sections of B, then the Koszul group in question is non-zero for very positive L.

description: The current trend in solar cell manufacturing is the implementation of a selective emitter to a
standard solar cell. A very high locally phosphorous doped emitter underneath the contacts is combined with a
high sheet resistance with low auger recombination at the illuminated area. An additional efficiency increase can
be achieved by good contact formation and high line conductivity of Light Induced Plated (LIP) contacts.
In this paper the important aspects of the direct plating technology for industrial production are summarized;
details on the metal layer systems Ni/Ag and Ni/Cu/Ag are shown.

description: The time-local master equation for a driven boson system interacting with a boson environment is derived by way of a time-local Heisenberg--Langevin equation. Extension to the driven qubit fails---except for weak excitation---due to the lost linearity of the system-environment interaction. We show that a reported time-local master equation for the driven qubit is incorrect. As a corollary to our demonstration, we also uncover odd asymptotic behavior in the "repackaged" time-local dynamics of a system driven to a far-from-equilibrium steady state: the density operator becomes steady while time-dependent coefficients oscillate (with periodic singularities) forever.

Despite the tetrapyrrolic nature of the porphyrin(2.1.2.1) scaffold, this is the first case of a pyrrole-based macrocycle which acts as a bipyridyl-like complexing ligand in the formation of an octahedral Re(I) complex. X-ray analysis and 1H NMR studies show that both Re(I) complexes (H2PY and H2PZ) consist of one octahedral Re(I) ion π-bonded to a dipyrrin unit and one protonated dipyrrin moiety linked together through o-phenylene bridges. This bonding behavior is compared to related metal complexes of porphyrin(2.1.2.1) macrocycles as well as other Re(I) porphyrins and demonstrates that the distorted conformation and, by virtue, the electronics of H2Por serve as a novel platform for examining structure property relationships which differ than those of other related planar porphyrin macrocycles.

description: This session includes two short keynote speeches and a panel discussion on the topic of “AI with and for Open Science”. It tackles this from different views, Ethics – Algorithms – Infrastructure, with the aim to see how AI supports researchers in their scientific discovery and what are the key ingridients for open infrastructures to make this happen. One of the primary ways AI is changing academia is through data analysis. Researchers can leverage AI algorithms to analyze vast amounts of data quickly and efficiently. This enables them to identify patterns, correlations, and trends that may not be easily discernible through traditional methods. Moreover, AI tools are being used to generate content, write code, resolve accessibility issues, reconfigure writing processes and detect plagiarism. All this is reshaping researcher practice and culture in how they communicate, how they share, how they view infrastructure. This session tackles the “AI with and for Open Science” topic from three views, Ethics – Algorithms – Infrastructure: Ethics in AI - principles and frameworks that put ethics and responsibility into practice in data analytics; dilemmas and challenges posed by work in AI and Data Science in the context of being transparent and accountable. Large Language Models (LLMs) – controlling the future of (open) access to science; how Generative AI tools may influence ways scientific output is accessed and legitimized; challenges and opportunities in developing and hosting these models and services. Open Infrastructure fit for LLM – having open-source text generation models and variations of them is a good thing as it enables research communities to adapt models to their domains faster, and to cut costs. How do we achieve this?

description: Sentiment Classification is a fundamental task in the field of Natural Language Processing, and has very important academic and commercial applications. It aims to automatically predict the degree of sentiment present in a text that contains opinions and subjectivity at some level, like product and movie reviews, or tweets. This can be really difficult to accomplish, in part, because different domains of text contains different words and expressions. In addition, this difficulty increases when text is written in a non-English language due to the lack of databases and resources. As a consequence, several cross-domain and cross-language techniques are often applied to this task in order to improve the results. In this work we perform a study on the ability of a classification system trained with a large database of product reviews to generalize to different Spanish domains. Reviews were collected from the MercadoLibre website from seven Latin American countries, allowing the creation of a large and balanced dataset. Results suggest that generalization across domains is feasible though very challenging when trained with these product reviews, and can be improved by pre-training and fine-tuning the classification model.

description: The recent detection by Advanced LIGO of gravitational waves (GW) from the merging of a binary black hole system sets new limits on the merging rates of massive primordial black holes (PBH) that could be a significant fraction or even the totality of the dark matter in the Universe. aLIGO opens the way to the determination of the distribution and clustering of such massive PBH. If PBH clusters have a similar density to the one observed in ultra-faint dwarf galaxies, we find merging rates comparable to aLIGO expectations. Massive PBH dark matter predicts the existence of thousands of those dwarf galaxies where star formation is unlikely because of gas accretion onto PBH, which would possibly provide a solution to the missing satellite and too-big-to-fail problems. Finally, we study the possibility of using aLIGO and future GW antennas to measure the abundance and mass distribution of PBH in the range [5 - 200] Msun to 10\% accuracy.

description: A new organic-inorganic hybrid material with copper(II) as the transition metal, piperazine as the organic component and mixed bromide/chloride as halide ions, (C4H12N2)[CuBr4]0.42[CuCl4]0.58·2H2O (1), has been prepared and crystallographically investigated by single-crystal X-ray diffraction. Unlike the parent chloride or bromide-based materials which adopt the monoclinic system, this mixed halide hybrid material crystallizes in the space group Pnma of the orthorhombic system with the following parameters: a = 12.3496(6) Å, b = 16.3147(11) Å, c = 6.4415(3) Å, V = 1397.83(12) Å3 and Z = 4. Its 0-D crystal packing is built of isolated entities, a copper(II) ion surrounded by four chloride/bromide ions [CuBr4]2- and [CuCl4]2-, a diprotonated diamine (C4H12N2)2+ and free water molecules. Additionally, these entities are linked through different types of intermolecular hydrogen bonds N-H…Br, N-H…Cl, N-H…Ow, Ow-H…Br, Ow-H…Cl, and weak non-covalent interactions C-H…Br and C-H…Cl [Ow = water oxygen]. The thermal decomposition of the precursor proceeds through four stages leading to copper(II) oxide as a final product. The title compound possesses antimicrobial and anti-tumoral effects comparable to two previously described compounds, as assessed by in silico examinations. Compound 1 inhibited in a dose dependent manner, the proliferation of gram negative and positive bacteria and exhibited a microbial lipase inhibition from Candida rugosa.

description: Optimal control approaches in combination with trajectory optimization have recently proven to be a promising control strategy for legged robots. Computationally efficient and robust algorithms were derived using simplified models of the contact interaction between robot and environment such as the linear inverted pendulum model (LIPM). However, as humanoid robots enter more complex environments, less restrictive models become increasingly important. As we leave the regime of linear models, we need to build dedicated solvers that can compute interaction forces together with consistent kinematic plans for the whole-body. In this paper, we address the problem of planning robot motion and interaction forces for legged robots given predefined contact surfaces. The motion generation process is decomposed into two alternating parts computing force and motion plans in coherence. We focus on the properties of the momentum computation leading to sparse optimal control formulations to be exploited by a dedicated solver. In our experiments, we demonstrate that our motion generation algorithm computes consistent contact forces and joint trajectories for our humanoid robot. We also demonstrate the favorable time complexity due to our formulation and composition of the momentum equations.

description: Lorentz-invariant massive gravity is usually associated with a strong coupling scale $Λ_3$. By including non-trivial effects from the Stueckelberg modes, we show that about these vacua, one can push the strong coupling scale to higher values and evade the linear vDVZ-discontinuity. For generic parameters of the theory and generic vacua for the Stueckelberg fields, the $Λ_2$-decoupling limit of the theory is well-behaved and free of any ghost or gradient-like instabilities. We also discuss the implications for nonlinear sigma models with Lorentzian target spaces.

description: Bakground: The goal of our study was to test the relative stability of urine, unconjugated, free catecholamines and the methyl derivatives. We measured the change in concentrations in commercially available urines after storage at various pH values, temperatures and time, from days up to 10 weeks. Methods: Samples of commercial control urines were adjusted to pH 2.0, 4.0, 6.0 and 8.0 and aliquots stored at ambient temperature (20–26°C), 4°C and –18oC. The free catecholamines (cats) and the free methyl derivatives (mets) were measured after 1, 2, 3 and 6 days and 1, 2, 3 and 10 weeks using the automated sample trace enrichment dialysis (ASTED) procedure with reversed phase ion pair high performance liquid chromatography (HPLC) and coulometric detection. Results: Free catecholamines were relatively stable, with <15% loss of concentration, when stored at pH 6.0 or less for at least 4 days and up to 10 weeks at pH 2.0 at either 4oC or –18oC. At pH 8.0, the concentration fell to <60% after 48 h and at a pH of 6.0 or 8.0, up to 90% was lost within the first week at 4oC and 25oC. More than 40% of free normetadrenaline and metadrenaline were lost after 1–2 weeks when stored at 20–25oC and pH 8.0. After 10 weeks at pH 4.0, 6.0 and 8.0, up to 90% loss was observed at 25oC. Free cats were stable at pH 2.0 and 4.0 at –18oC and the free mets were stable at –18oC over the entire time period studied and at all pHs. Conclusions: In the analysis of free catecholamine and the free methyl derivatives, urine samples should be acidified to a pH range 2.0–3.0 to ensure stability and hence the correct analysis.

description: Ge QDs were fabricated in Si3N4 matrix with a substrate heating method. Various substrate
temperatures were attempted from 400 - 600°C. TEM, GIXRD and Raman spectroscopy were carried out structural
analysis showing a uniformly sized quantum dots (QDs). Optical properties were studied by measuring transmission
and reflection spectra and calculating the absorption and the absorption coefficient. Unfortunately no blue shift of the
absorption edge was identified, which could a direct evidence for the quantum confinement. A single layer of Ge
QDs in between of the two Si3N4 barrier layers was structured as a double barrier resonant diode (DBRD) for hot
carrier solar cells. The IV characteristic of the DBRD showed a linear response with a valley exhibiting a negative
differentia resistance.

description: White colored grid fingers reduce the optical width of the fingers which leads to a gain in short circuit
current density Jsc = 0.6 %rel. Incoming rays are reflected at the white painted fingers instead of being absorbed at
the metallic surface. The reflected rays are totally internally reflected at the glass air interface of the module with a
probability of approx. 50% and have another chance to reach the active cell area. White grid fingers reduce the
optical width of the shadowed area in solar modules without increasing the series resistance. Optimizing the size of
the white painted contact fingers, leading to an optical width half as large as the real width of the fingers achieves a
simulated gain in short circuit current density Jsc = 3 %.

description: Leading approaches to fault-tolerant quantum computation dedicate a significant portion of the hardware to computational factories that churn out high-fidelity ancillas called magic states. Consequently, efficient and realistic factory design is of paramount importance. Here we present the most detailed resource assessment to date of magic state factories within a surface code quantum computer, along the way introducing a number of new techniques. We show that the block codes of Bravyi and Haah [Phys. Rev. A 86, 052329 (2012)] have been systematically undervalued; we track correlated errors both numerically and analytically, providing fidelity estimates without appeal to the union bound. We also introduce a subsystem code realisation of these protocols with constant time and low ancilla cost. Additionally, we confirm that magic state factories have space-time costs that scale as a constant factor of surface code costs. We find that the magic state factory required for post-classical factoring can be as small as 6.3 million data qubits, ignoring ancilla qubits, assuming $10^{-4}$ error gates, and the availability of long range interactions.

description: Two binucelar oxidovanadium complexes, [(VO2)2(µ-Hpydn)2] (1) and [(VO)2(µ-pydn)2(bpy)2]·5H2O (2), where pydn = pyridoxine and bpy = 2,2’-bipyridine, were synthesized and characterized by elemental analysis and infrared (IR), electron paramagnetic resonance (EPR), and electronic (UV-vis) spectroscopies. The structure of 2 was determined by single-crystal X-ray diffraction analysis. It is comprised of two distorted octahedral oxidovanadium(IV) centers with a terminal bpy ligand and bridged by the methoxido group of the pydn ligands, forming the {VIVO(µ-OR)2}2+ core with anti-orthogonal configuration. Density functional theory (DFT) calculations at the B3LYP/LANL2DZ level were used to obtain the optimized geometries and to study the electronic structure of 1 and 2. For 2, EPR analysis in the solid state, magnetic susceptibility measurements and the theoretical magnetic exchange coupling constant (J) of 20.1 cm−1 indicate a weak ferromagnetic coupling. 51V NMR and EPR spectroscopies suggest partial breakage of both binuclear structures in solution. Both complexes act as pre-catalysts for the bromination of phenol red to phenol blue in the presence of KBr, H2O2 and perchloric acid.

description: A new screen-printable paste flux additive has been developed that improves p-type crystalline silicon
solar cell performance compared to current industry standard commercial pastes. Solar cells fabricated using the new
flux additive paste (DuPont™ Solamet® PV17x) have conductor line-silicon contact interface films that are more
uniform and have nanometer-scale thicknesses (<10nm). The ultra-thin, uniform interfacial films result in improved
solar cell performance on 65ohm/sq. emitters through improved conductor line contact resistivity (1.26mohm-cm2) and
improved contact resistivity variability, improved series resistance and open circuit voltage, and reduced
emitter/junction damage. The inherent low contact resistivity and reduced emitter/junction damage also enable contact
to lightly doped, high-sheet-resistance emitters.

description: We report the discovery of eight new giant planets, and updated orbits for four known planets, orbiting dwarf and subgiant stars using the CORALIE, HARPS, and MIKE instruments as part of the Calan-Hertfordshire Extrasolar Planet Search. The planets have masses in the range 1.1-5.4MJs, orbital periods from 40-2900 days, and eccentricities from 0.0-0.6. They include a double-planet system orbiting the most massive star in our sample (HD147873), two eccentric giant planets (HD128356b and HD154672b), and a rare 14 Herculis analogue (HD224538b). We highlight some population correlations from the sample of radial velocity detected planets orbiting nearby stars, including the mass function exponential distribution, confirmation of the growing body of evidence that low-mass planets tend to be found orbiting more metal-poor stars than giant planets, and a possible period-metallicity correlation for planets with masses >0.1MJ, based on a metallicity difference of 0.16 dex between the population of planets with orbital periods less than 100 days and those with orbital periods greater than 100 days.
