The aim of this study was to evaluate effects of incorporating red Hibiscus sabdariffa seed meal into the feed ration on the growth performance, carcass characteristics and economic margins of broiler chickens in Côte d'Ivoire. To achieve this, 237 broiler chicks of the Cobb500 strain, two (2) weeks old, were divided into three (3) lots of 79 birds each. lot 1 was fed with ration that did not contain Hibiscus sabdariffa red variety (HSR0) seed meal. Lots 2 and 3 were fed respectively by ration HSR 2% and HSR 4% by which contain 2 % and 4 % of Hibiscus sabdariffa seed meal respectively. The results showed that the inclusion of Hibiscus sabdariffa seeds significantly reduced food consumption in subjects fed HSR 2 and HSR 4 compared with ration HSR 0 (control). It varied from 38.71 ± 1.26 g/d to 161 ± 5.08 g/d for lot 2 and from 37.85 ± 1.16 g/d to 148 ± 6.08 g/d for lot 3 compared with 39.8±1.3 g/dr to 172 ± 7.2 g/d for lot 1. On other hand, the subjects in lot 2 achieved better growth performance than the other lots. They recorded an average weight of 2,334±208.6 g compared with 2,213 ± 170.78 g and 1,958 ± 182.57 g for lots 1 and 3 respectively. Over the 4-week period, the highest mortality rate was observed in lot 1, at 10.13 %. No negative effect was observed on the carcass yield of chickens fed Hibiscus sabdariffa meal. In economic terms, incorporation reduced the production cost of broilers. In conclusion Hibiscus sabdariffa seeds can therefore be incorporated up to 2% into chicken rations without causing any significant loss in chicken weight. Studies need to be carried out to improve the organoleptic quality of Hibiscus sabdariffa seeds.

The Kodihalli sub-watershed (4D4D2f) is lies between 14028’23.68”-14034’20.103” North latitudes and 75026’49.224”-75031’44.208” East longitudes and covers an area of about 4398.83 ha. with an average annual rainfall of 783.0 mm (2014-2021). The maximum rainfall of 439.0 mm is received from June to September, 226.0 mm from October to early December and the remaining 118.0 mm is received during the rest of the year. The number of rainy days (>2.5 mm) varied from 13-24 days per year. On an average, the number of rainy-day events likely to produce runoff (20 to 30 mm) are about 2 to 8 rainy days per year with moderate variation across the years. The Actual Evapotranspiration (AET) over the years 2014 - 2021 in the Kodihalli sub-watershed varied from 383.0 to 770.0 mm. During 2014 - 2021, the average annual AET (621.0 mm) was less than the average rainfall (783.0 mm). The average AET/P ratio between 2014-2021 was about 0.79 which is less than the sustainable limit of about 0.80. The soils of watershed viz., sandy clay loam (IR 10 mm/hr) and sandy clay (IR 14 mm/hr) resulted in more infiltration rate than clay (2 mm/hr) and clay loam soils (7 mm/hr). Soil infiltration during a rainstorm is closely related to a number of factors such as the intensity and kinetic energy of the rainfall, soil surface conditions and soil properties such as those related to aggregate stability. For effective soil and water conservation, maximum area of about 3769 ha (85.7%) requires graded bunding and 267 ha (6.06%) area requires contour bunding.

AbstractCovalent polymer networks (CPNs) are of great technological interest due to their robustness and tunability; however, they are rarely applied as semiconductors in optoelectronic devices due to poor material processability. Herein, a simple, rapid, and powerful approach is reported to prepare CPN thin films based on an in situ thermal azide–alkyne cycloaddition (TAAC) in the absence of catalyst or solvent. The method is demonstrated with perylenediimide and triazine‐based monomers, and affords smooth and homogenous CPN films through solution processing and heat treatment (10 min). Moreover, the site‐specific TAAC realizes semiconducting CPNs without undesired impurities or byproducts, and tunable optoelectronic properties are achieved by varying the reaction temperature, which affects the intermolecular self‐assembly. The obtained CPN films exhibit exceptional solvent resistance and good n‐type semiconducting behavior, which together afford application in a series of multilayer solution‐processed organic photovoltaics, where the presence of CPN films significantly improves the solar energy conversion efficiency to over 8% (7% in control devices) when the CPN is used in a planar‐mixed heterojunction device architecture.
Metal–Organic Frameworks (MOFs)‐Derived Nitrogen‐Doped Porous Carbon Anchored on Graphene with Multifunctional Effects for Lithium–Sulfur Batteries

Published: February 2018

AbstractLithium–sulfur (Li–S) batteries are highly appealing for next‐generation electrochemical energy storage owing to their high theoretical energy density, environmental friendliness, and low cost. However, the insulating nature of sulfur and migration of dissolved polysulfide intermediates lead to low active material utilization and fast capacity decay, which pose a significant challenge to their practical applications. Here, this paper reports a multifunctional carbon hybrid with metal–organic frameworks (MOFs)‐derived nitrogen‐doped porous carbon anchored on graphene sheets (NPC/G) serving as a sulfur host. On the one hand, the high surface area and nitrogen‐doping of the carbon nanoparticles enable effective polysulfide immobilization through both physical confinement and chemical adsorption; on the other hand, the highly conductive graphene provides an interconnected conductive framework to facilitate fast electron transport, improving the sulfur utilization. As a result, the NPC/G‐based sulfur cathode exhibits a high specific capacity of 1372 mAh g−1 with good cycling stability over 300 cycles. This approach provides a promising approach for the design of MOFs‐derived carbon materials for high performance Li–S batteries.

Abstract2D van der Waals (vdW) layered polar crystals sustaining phonon polaritons (PhPs) have opened up new avenues for fundamental research and optoelectronic applications in the mid‐infrared to terahertz ranges. To date, 2D vdW crystals with PhPs are only experimentally demonstrated in hexagonal boron nitride (hBN) slabs. For optoelectronic and active photonic applications, semiconductors with tunable charges, finite conductivity, and moderate bandgaps are preferred. Here, PhPs are demonstrated with low loss and ultrahigh electromagnetic field confinements in semiconducting vdW α‐MoO3. The α‐MoO3 supports strong hyperbolic PhPs in the mid‐infrared range, with a damping rate as low as 0.08. The electromagnetic confinements can reach ≈λ0/120, which can be tailored by altering the thicknesses of the α‐MoO3 2D flakes. Furthermore, spatial control over the PhPs is achieved with a metal‐ion‐intercalation strategy. The results demonstrate α‐MoO3 as a new platform for studying hyperbolic PhPs with tunability, which enable switchable mid‐infrared nanophotonic devices.

AbstractA Cu(I)‐catalyzed regioselective cross‐dehydrogenative coupling of indoline with a variety aryl and alkyl carboxylic acids is described. The divergent process for the oxygenation was achieved in satisfactory yields under additive free conditions, which provides an efficient strategy for the regioselective C7 functionalization of indolines using inexpensive copper catalyst. Oxygen as the sole oxidant is required in this protocol. The method is tolerated by a wide range of functional groups. Preliminary mechanistic study provided support for a reversible C−H bond metallation step.magnified image
Graphite as Cointercalation Electrode for Sodium‐Ion Batteries: Electrode Dynamics and the Missing Solid Electrolyte Interphase (SEI)

AbstractThe intercalation of solvated sodium ions into graphite from ether electrolytes was recently discovered to be a surprisingly reversible process. The mechanisms of this “cointercalation reaction” are poorly understood and commonly accepted design criteria for graphite intercalation electrodes do not seem to apply. The excellent reversibility despite the large volume expansion, the small polarization and the puzzling role of the solid electrolyte interphase (SEI) are particularly striking. Here, in situ electrochemical dilatometry, online electrochemical mass spectrometry (OEMS), a variety of other methods among scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X‐ray diffraction (XRD) as well as theory to advance the understanding of this peculiar electrode reaction are used. The electrode periodically “breathes” by about 70–100% during cycling yet excellent reversibility is maintained. This is because the graphite particles exfoliate to crystalline platelets but do not delaminate. The speed at which the electrode breathes strongly depends on the state of discharge/charge. Below 0.5 V versus Na+/Na, the reaction behaves more pseudocapacitive than Faradaic. Despite the large volume changes, OEMS gas analysis shows that electrolyte decomposition is largely restricted to the first cycle only. Combined with TEM analysis and the electrochemical results, this suggests that the reaction is likely the first example of a SEI‐free graphite anode.

AbstractReceptor–neurotransmitter molecular recognition is key for neurotransmission. Although crystal structures of the receptors are known, the mechanism for recognition is not clear. Reported here is the ultraviolet (UV) and infrared (IR) spectra of complexes between a partial peptide (SIVSF), mimicking the binding motif of a catechol ring in the adrenergic receptor, and various ligands. The UV spectra show that two isomers coexist in the complex of SIVSF with properly recognized ligands, such as protonated adrenaline (adrenalineH+). From IR spectra, they are assigned to catechol‐ and amino‐bound structures. The catechol‐bound structure is not observed when the ligand is replaced by nonproper molecules, such as noradrenalineH+. The results suggest that SIVSF not only recognizes the catechol ring but can distinguish differences in the amine side chain. The method provides a new possibility for screening molecules as potential therapeutics for activating the receptor.

Published: February 2018

In this study, a novel heterogeneous palladium catalyst was synthesized by anchoring palladium onto ethylenediaminetetraacetic acid (EDTA)‐coated Fe3O4@SiO2 magnetic nanocomposite and used for the Suzuki and Sonogashira cross‐coupling reactions. The properties of the magnetic catalyst were characterized by FT‐IR, XRD, TEM, FE‐SEM, DLS EDX, XPS, N2 adsorption‐desorption isotherm analysis, TGA, VSM, elemental analysis and the loading level of Pd in catalyst was measured to be 0.51 mmol/g by ICP. The catalyst was used in Suzuki cross‐coupling reactions of various aryl halides, including less reactive chlorobenzenes with phenylboronic acid without any additive or ligand under green conditions. Furthermore, we have reported this recyclable catalytic system for Sonogashira cross‐coupling reactions of various aryl halides (I, Br, Cl) under copper and ligand‐free conditions in the presence of DMF/H2O (1:2/v:v) as a solvent. The magnetic catalyst could also be separated by an external magnet and reused six times without any significant loss of activity.

AbstractMolecular oxygen in living cells is distributed and consumed inhomogeneously, depending on the activity of each organelle. Therefore, tractable methods that can be used to monitor the oxygen status in each organelle are needed to understand cellular function. Here we report the design of a new oxygen‐sensing probe for use in the cell nucleus. We prepared “Ru‐Hoechsts”, each consisting of a phosphorescent ruthenium complex linked to a Hoechst 33258 moiety, and characterized their properties as oxygen sensors. The Hoechst unit shows strong DNA‐binding properties in the nucleus, and the ruthenium complex shows oxygen‐dependent phosphorescence. Thus, Ru‐Hoechsts accumulated in the cell nucleus and showed oxygen‐dependent signals that could be monitored. Of the Ru‐Hoechsts prepared in this study, Ru‐Hoechst b, in which the ruthenium complex and the Hoechst unit were linked through a hexyl chain, showed the most suitable properties for monitoring the oxygen status. Ru‐Hoechsts are probes with high potential for visualizing oxygen fluctuations in the nucleus.
All stent strut malappositions are not created equal
Authors: Uretsky Barry F. 
Published: February 2018

Key Points

The current meta‐analysis evaluates the relationship of late incomplete stent apposition (LISA) observed either by IVUS or OCT 6–18 months after PCI and long‐term outcomes, particularly in regard to stent thrombosis (ST) and has demonstrated a small but significant increase in ST with LISA.
The results of the current study do not apply to acute stent malapposition whose relevance to adverse outcomes is uncertain based on current evidence and a malapposition classification based on presence, length, and severity of malapposed struts.
A classification of stent malapposition based on cause of malapposition is proposed as a method to determine prognostic importance of acute incomplete stent apposition.
