Published: February 2020

Reactive Black 5 (RB5) is one of the synthetic reactive dyes most used in the textile industry, due to its solubility in water and reactive groups which form covalent bonds within the fiber. In the process of dyeing fabrics, however, it is estimated that 12-14% of dyes are released into the effluent. This work evaluated the biodegradation of RB5 dye, adsorbed in polyurethane foam, by basidiomycetes (Phanerochaete chrysosporium ATCC 24725, Pleurotus ostreatus and Pleurotus floridae). Results were evaluated considering the partial- or total medium discoloration, the adsorption capacity of the dye in the polyurethane foam (PUF) and the respirometric measurements. The results showed that Phanerochaete chrysosporium was able to partially degrade 50 mg L-1 of RB5 in pH 6.0, when cultivated in Petri dishes. When this microorganism was cultivated in PUF cubes saturated with RB5 solution (50 mg L-1, pH 6.0), CO2 production reached an accumulated value of 2.16 mg on the fifteenth day, revealing the growth of the microorganism and consequently the contaminant degradation, which was used as the source of nutrients.
Environmentally Assisted Cracking of Subsea Pipelines in Oil & Gas Production Environments—Effect of Static Loading
Authors: Thodla Ramgopal , Gui Feng , Holtam Colum 
Published: February 2020

Fatigue crack growth rate of line pipe steels in sour environments typically exhibits a steady-state value at low frequencies. However, in highly inhibited sour environments, there is no evidence of a steady-state fatigue crack growth at low frequencies. This is likely a result of static crack growth rate at Kmax. Stable static crack growth measured under constant stress intensity factor (K) conditions in inhibited sour environments was in the range of 10−7 mm/s to 10−8 mm/s. The crack growth rate in inhibited sour environments is likely associated with crack tip processes associated with metal dissolution/film formation and associated hydrogen evolution. The results obtained were modeled based on a crack tip strain rate based approach, where the rate limiting step was the metal dissolution/FeS formation and the corresponding hydrogen generation reaction.

Abstract. Total hydroxyl radical (OH) reactivity measurements were conducted during the LANDEX intensive
field campaign in a coniferous temperate forest located in the Landes area,
southwestern France, during July 2017. In order to investigate inter-canopy and intra-canopy variability, measurements were performed inside (6 m) and above the canopy level (12 m), as well as at two different locations within the canopy, using a comparative reactivity method (CRM) and a laser photolysis–laser-induced fluorescence (LP-LIF) instrument. The two techniques were intercompared at the end of the campaign by performing measurements at the same location. Volatile organic compounds were also monitored at both levels with a proton transfer time-of-flight mass spectrometer and online gas chromatography instruments to evaluate their contribution to total OH reactivity, with monoterpenes being the main reactive species emitted in this forest dominated by Pinus pinaster Aiton. Total OH reactivity varied diurnally, following the trend of biogenic volatile organic compounds (BVOCs), the emissions and concentrations of which were dependent on meteorological parameters. Average OH reactivity was around 19.2 and 16.5 s−1 inside and above the canopy, respectively. The highest levels of total OH reactivity were observed during nights with a low turbulence (u*≤0.2 m s−1), leading to lower mixing of emitted species within the canopy and thus an important vertical stratification characterized by a strong concentration gradient. Comparing the measured and the calculated OH reactivity highlighted an average missing OH reactivity of 22 % and 33 % inside and above the canopy, respectively. A day–night variability was observed on missing OH reactivity at both heights. Investigations showed that during daytime, missing OH sinks could be due to primary emissions and secondary products linked to a temperature-enhanced photochemistry. Regarding nighttime missing OH reactivity, higher levels were seen for the stable and warm night of 4–5 July, showing that these conditions could have been favorable for the accumulation of long-lived species (primary and secondary species) during the transport of the air mass from nearby forests.
The Aisthetic-Cosmological Dimension of María Lugone's Decolonial Feminism
Authors: Vallega Alejandro A. 
Published: February 2020

Abstract
In her work on decolonial feminism María Lugones expands and strengthens the task of decolonial thinking. On the one hand this occurs as gender becomes explicitly part of the very ways of being under modernity, and this means that gender, race, and labor are always entangled in the coloniality of power. As a result decolonial thought may only occur by the critique of one's concrete situation in the living intersectionality in which identities and power relations are founded. This turn to concrete intersectionality occurs as Lugones thinks in light of cosmological indigenous lineages in América,1 and with this turn engages not only the logical, epistemic, and conceptual levels of coloniality but, in a turn that makes possible the affirmation of subjugated knowledges, she turns to the aisthetic dimensions of the coloniality of power and knowledge: Most significantly, in this way, she is able to begin to think with the liberatory rhythms, movements, practices that are our lives as sites of resistance and contestation never subsumed (abarcadas) by the coloniality of power, modernity, and capitalism.
Stillness, Aesthesis, Resistance
Authors: Rivera Omar 
Published: February 2020

Abstract
Emphasizing the embodied, physical aspect of María Lugones's decolonial feminism, this article elucidates ways in which the oppressed appears to colonizing gazes and beyond them in order to explore possibilities of resistance. It proposes “stillness” as a sentient physicality that can transgress the hold of racist/colonizing gazes and sense a multiplicity of worlds from a limen. In order to do this, it focuses on the temporality of “stillness” and on modes of appearing of resistant praxis.
Compelled to Cross, Tempted to Master: Affective Challenges in Lugones's Decolonial Feminist Methodology
Authors: Roshanravan Shireen 
Published: February 2020

Abstract
This article explores the affective challenges of María Lugones's coalitional imperative of decolonial feminism as it requires sustaining painful confrontations for acting in complicity with the very oppressions the aspiring decolonial feminist may have believed herself to be entirely against. Because the coalitional crossings necessary to Lugones's decolonial feminist methodology involves moving toward discomfort out of a sense of responsibility, the decolonial feminist may be tempted toward mastery of radical performance rather than self-transformation. As a possible way out of this temptation toward mastery, this article turns to Lugones's own affective animation of her methodological commitment to live the coalitional imperative with a love rooted in, and routed through, an intimate sense of interdependence with other resisters at the colonial difference.
Interlocking, Intersecting, and Intermeshing: Critical Engagements with Black and Latina Feminist Paradigms of Identity and Oppression
Authors: Belle Kathryn Sophia 
Published: February 2020

Abstract
Inspired by Mariana Ortega's invitation to reflect on diverse iterations of intersectionality, this article focuses on María Lugones's engagements with two Black feminist concepts, namely, interlocking oppressions (as articulated by Barbara Smith, Beverley Smith, and Demita Frazier) and intersectionality (as articulated by Kimberlé Crenshaw). It explores these concepts alongside Lugones's use of her own terms such as intermeshed, curdling, multiplicity, and fusion, in several paradigm shifting essays, specifically, “Purity, Impurity, and Separation” (1994 and 2003), “Tactical Strategies of the Street Walker” (2003), “On Complex Communication” (2006), “Heterosexism and the Colonial/Modern Gender System” (2007), “Toward a Decolonial Feminism” (2010), “Methodological Notes Toward a Decolonial Feminism” (2011), and “Radical Multiculturalism and Women of Color Feminisms” (2014). It also underscores Ortega's important contributions bringing these Black and Latina feminist concepts together in philosophically productive ways—in a spirit of collaboration and coalition rather than zero-sum competition.
Direct and Indirect Energy Rebound Effects in German Households: A Linearized Almost Ideal Demand System Approach
Authors: Schmitz Hendrik , Madlener Reinhard 
Published: February 2020

We estimate direct and indirect energy rebound effects for a wide variety of goods and services in Germany. To this end, we employ a linearized approximation of the popular Almost Ideal Demand System (AIDS) approach suggested by Deaton and Muellbauer (1980). Excluding measures of energy efficiency when estimating rebound can lead to biased results. We compensate for this shortcoming of previous research by explicitly accounting for energy efficiency in our estimations. Using data for Germany from 1970 to 2017, we find moderate direct and significant indirect rebound effects for different energy carriers across four model specifications. The size of the rebound effect proves to be sensitive to the expenditure shares used for the calculations, which in some cases leads to negative overall rebound estimates.

Background
MicroRNAs (miRNAs) exist widely and are involved in multiple biological processes in ducks, whereas the regulatory mechanism of miRNAs in egg laying of ducks has remained unclear. This study aims to reveal key miRNAs involved in the regulation of egg production in duck ovaries.

Methods
High-throughput sequencing was performed on four egg-type duck ovaries and four egg-meat-type duck ovaries at the start of the egg-laying stage. Quantitative reverse transcription PCR (qRT-PCR) validation was performed on differentially expressed miRNAs (DE miRNAs). Gene network of DEmiRNA-mRNA-pathway was constructed by Cytoscape.

Results
A total of 251 know miRNAs and 1,972 novel miRNAs were obtained from whole clean reads. Among the known miRNAs, we identified 21 DEmiRNAs, including eight down-regulated and 13 up-regulated miRNAs in egg-type ducks compared with egg-meat-type ducks. Among the novel miRNAs, we identified 70 DEmiRNAs, including 58 down-regulated and 12 up-regulated in egg-type ducks compared with egg-meat-type ducks. The expression patterns of four miRNAs were verified by qRT-PCR. The DEmiRNAs were involved in the function of response to folic acid and the pathway of valine, leucine and isoleucine degradation. Specific target genes of DEmiRNAs enrichment was found in some egg-laying regulation pathways, such as dopaminergic synapse, ovarian steroidogenesis and oocyte meiosis. The DEmiRNA-mRNA-pathway network including three DEmiRNAs, nine mRNAs and 11 pathways. apl-miR-194-5p and apl-miR-215-5p may be potential key miRNAs in regulating egg laying.

Conclusions
This study provided miRNAs profiles in ducks about egg laying and establish a theoretical basis for subsequent selection or modification of duck phenotypes at the molecular level.
Leader‐following consensus of fractional‐order multi‐agent systems via adaptive control
Authors: Ji Yude , Guo Yanping , Liu Yuejuan , Tian Yun 
Published: February 2020

SummaryThis article focuses on the consensus problem of leader‐following fractional‐order multi‐agent systems (MASs) with general linear and Lipschitz nonlinear dynamics. First, the distributed adaptive protocols for linear and nonlinear fractional‐order MASs are constructed, respectively. We allow the control coupling gains to be time varying for each agent. Moreover, the adaptive modification schemes for the control gain are designed, which renders smaller control gains and thus requires smaller amplitude on the control input without sacrificing consensus convergence. Second, based on fractional‐order Lyapunov stability theorem and Barbalat's lemma, two novel sufficient conditions in terms of linear matrix inequalities are provided to ensure that the leader‐following consensus can be obtained in the case for any undirected connected communication graph. Furthermore, we show that the proposed algorithm also works for consensus of agents with intrinsic Lipschitz nonlinear dynamics. As a result, the proposed framework requires no global information and thus can be implemented in a fully distributed manner. Finally, the numerical simulations are given to demonstrate the effectiveness of obtained the theoretical results.

AbstractSoft electronics that seamlessly interface with skin are of great interest in health monitoring and human–machine interfaces. However, achieving mechanical softness, skin adhesiveness, and high conductivity concurrently has always been a major challenge due to the difficulty in bonding dissimilar materials while retaining their respective properties. Herein, the mechanically interlocked hydrogel–elastomer hybrid is reported as a viable solution to this problem. Hydrogels with low moduli and high adhesiveness are employed as the substrate, while porous elastomer webs are used as matrices to load conductive films and lock the hydrogels through a mechanically interlocked structure. The bonding strength between the hydrogel and elastomer in the interlocking hybrid structure is 14.3 times of that obtained via the physical stacking method. As a proof of concept, interlocking hybrids are used as on‐skin electrodes for electrophysiological signal recording including electromyography and electrocardiography. The robust hybrid electrodes are able to detect signals after multiple cycles. The proposed strategy not only is an effective approach to achieve interlocking structures, but also provides a new perspective for soft and stretchable electronics.
Material‐Dependent Antagonistic Effects between Soot and ZDDP
Authors: Kumara Chanaka , Meyer Harry M. , Qu Jun 
Published: February 2020

AbstractWhile soot in engine oil is known to accelerate the wear of diesel and gasoline direct‐injection compression‐ignition engines, there is a lack of consensus on the wear mechanism though various hypotheses have been proposed in the literature. Particularly, some recently observed antagonistic effects between soot and a common lubricant antiwear additive, zinc dialkyldithiophosphate (ZDDP), while others did not. The discrepancy is, in part, explained by the strong alloy dependence of such antagonism discovered in this study. Four alloys, 52100 steel and M2, M50, and A2 tool steels, are tested in lubricants containing carbon black (CB, a soot surrogate) with and without ZDDP present. Adding the CB alone to the oil increases the wear rate for all steel alloys as expected. However, distinct wear performance is observed for the four steel alloys when ZDDP is introduced to the CB‐containing oil: while the 52100 steel has notable wear reduction, the three tool steels suffer significant wear increase. Comprehensive tribofilm characterization suggests that the Mo content in the steel alloy and the sulfur from ZDDP strongly influence wear behavior. The combination of CB/Mo‐catalyzed sulfidation and CB‐accelerated abrasion is hypothesized to be responsible for the high wear of the Mo‐alloyed tool steels.
Chiral Phosphoric Acid Catalyzed Atroposelective C−H Amination of Arenes

Published: February 2020

AbstractN‐arylcarbazole structures are important because of their prevalence in natural products and functional OLED materials. C−H amination of arenes has been widely recognized as the most efficient approach to access these structures. Conventional strategies involving transition‐metal catalysts suffer from confined substrate generality and the requirement of exogenous oxidants. Organocatalytic enantioselective C–N chiral axis construction remains elusive. Presented here is the first organocatalytic strategy for the synthesis of novel axially chiral N‐arylcarbazole frameworks by the assembly of azonaphthalenes and carbazoles. This reaction accommodates broad substrate scope and gives atropisomeric N‐arylcarbazoles in good yields with excellent enantiocontrol. This approach not only offers an alternative to metal‐catalyzed C–N cross‐coupling, but also brings about opportunities for the exploitation of structurally diverse N‐aryl atropisomers and OLED materials.

Published: February 2020

AbstractA strategy that uses carbon monoxide (CO) as a molecular trigger to switch the polymerization mechanism of a cobalt Salen complex [salen=(R,R)‐N,N′‐bis(3,5‐di‐tert‐butylsalicylidene)‐1,2‐cyclohexanediamine] from ring‐opening copolymerization (ROCOP) of epoxides/anhydrides to organometallic mediated controlled radical polymerization (OMRP) of acrylates is described. The key phenomenon is a rapid and quantitative insertion of CO into the Co−O bond, allowing for in situ transformation of the ROCOP active species (Salen)CoIII‐OR into the OMRP photoinitiator (Salen)CoIII‐CO2R. The proposed mechanism, which involves CO coordination to (Salen)CoIII‐OR and subsequent intramolecular rearrangement via migratory insertion has been rationalized by DFT calculations. Regulated by both CO and visible light, on‐demand sequence control can be achieved for the one‐pot synthesis of polyester‐b‐polyacrylate diblock copolymers (Đ<1.15).

AbstractRecent advances in additive manufacturing made it feasible to fabricate products with desired shapes and features. Herein, a new, photocurable 3D printer ink mainly based on pentaerythritol triacrylate (PETA) is reported. To achieve rapid curing needed for 3D printing process, high performance water‐soluble photoinitiator, lithium phenyl‐2,4,6‐trimethylbenzoylphosphinate (LAP), was emulsified in PETA monomers and this suspension was evaluated for its polymerization kinetics by exposing to 395 nm UV‐light. The distinct influences of LAP and triethanolamine (TEA) concentrations on photo‐polymerization and printability were examined and an optimum concentration for extrusion‐based 3D printing was found to be 10 mMand 1.62 M for LAP and TEA, respectively. Synthesized PETA‐based 3D printer ink was functionalized by dispersing magnetic particles/flakes into the mixture, and consequently, a magneto responsive ink was obtained to be used in specialized applications. A ring‐shaped structure embedded with micron sized iron flakes was printed as a prototype. This study presents a versatile photo‐curable polymer formulation with possible translation to high performance 3D printing of customizable shapes that can be utilized in a wide range of areas such as micro‐robotics and medical science.
Optimal storage moduli for the thermal healing of polystyrene ionomers
Authors: Kim Eun‐Hee , Jo Myung Guen , Kim Joon‐Seop 
Published: February 2020

AbstractIn this work, we studied the effects of storage moduli on thermal healing of poly(styrene‐co‐methacrylate) and poly(styrene‐co‐itaconate) ionomers. It was found that as the ion content and neutralization degree of the ionomers increased, the healing efficiencies decreased. This was due to the fact that the ionic aggregates, acting as physical cross‐links, and the clustered regions of the ionomers, reducing polymer chain mobility, interrupted the relaxation of the polymer chains near the damaged site, slowing the recovery. The most important finding in this work was that, to heal the ionomer without severe sample deformation, the optimal healing temperature should be the temperature where the storage modulus of the ionomer was similar to 106.6 Pa. Obviously, the healing rate and healing efficiency were mainly influenced by the healing temperature, related directly to the storage modulus of the polymer, and the maximum healing efficiency was strongly affected by healing time.
