Published: May 2022

AbstractLiquid‐phase catalytic exchange (LPCE) of hydrogen isotopes has extensive application in upgrading of recycled water and wastewater treatment. This low‐temperature catalytic exchange requires hydrophobic catalysts for keeping high exchange efficiency and catalytic stability. To eliminate diffusional influences in conventional porous catalysts, we designed a flat catalyst coating with fully exposed platinum (Pt) active sites by two steps. The hydrophobic coating was firstly established by superhydrophobic silica nanospheres (SSNs) and then Pt nanoparticles were dispersed on the surface of coating by ion sputtering. By adjusting the time of ion sputtering, the catalytic exchange efficiency of optimized catalyst coating (50‐Pt/SSNs/PDMS) improved up to 86% at 60 °C and maintained stability for at least 5 h, behaving high catalytic exchange efficiency and good stability. Besides, the turnover frequency of the 50‐Pt/SSNs/PDMS was 1.7 times than that of “PDMS+Pt/SSNs” prepared by “glue+power” method. The “step by step” strategy can effectively improve the utilization of Pt and provide a new idea for the preparation of Pt‐based hydrophobic catalysts.

AbstractIn this study, we re‐examine the nexus of environmental performance and financial performance by benchmarking firms relative to their industry peers based on environmental performance in a given year to identify best‐in‐class and worst‐in‐class firms. After correcting for distributional issues while using environmental performance scores (i.e., clustering scores around the median and material differences within industries and time) and financial performance ratios (i.e., the potential impact of extreme values), we find that best‐in‐class firms exhibit higher financial performance than their industry peers (i.e., worst‐in‐class and average firms). Our findings are robust to alternative measures of environmental performance (i.e., subdimensions of environmental performance) and financial performance. Finally, our results are robust to different identification strategies. Our findings present important and timely policy implications for firms, ESG fund managers and investors.

AbstractObjectivesPerihilar cholangiocarcinoma (PCC) is a complex disorder involving the hepatic hilum. Multiple endoscopic retrograde cholangiopancreatography sessions are necessary for diagnosis and treatment with underlying cholangitis risk. Our aim is to clarify the initial‐drainage‐related prognostic factors of PCC.MethodsThis study was a single‐center retrospective study. A total of 104 consecutive patients diagnosed with PCC from January 2010 to February 2020 were enrolled. We defined the diagnostic period as the time between the first biliary drainage attempt and the final drainage when treatment, including surgery or chemotherapy, was started. We focused on this initial period and analyzed the endoscopy‐related factors that affected mortality.ResultsOverall survival of all PCC patients was 599 days. Overall survival of surgically treated patients and unresectable patients were 893 days and 512 days, respectively. In 48 surgically treated patients, drainage‐related cholangitis within the diagnostic period, defined as new cholangitis that occurred after the first biliary drainage attempt, worsened overall survival from 1460 days to 607 days. Endoscopic sphincterotomy, the first drainage method other than endoscopic nasobiliary drainage, and four or more endoscopic retrograde cholangiopancreatography sessions were risk factors for drainage‐related cholangitis. Drainage‐related cholangitis increased pathological lymph node metastasis. Percutaneous transhepatic biliary drainage as final drainage was the only prognostic factor in unresectable chemotherapy‐treated patients.ConclusionsDrainage‐related cholangitis worsened the prognosis in PCC patients who underwent surgery. Appropriate endoscopic retrograde cholangiopancreatography strategies, especially during the diagnostic period, are of great importance in PCC.

Published: May 2022

AbstractAquaculture is one of the most developing sectors worldwide, and it contributes to enhancing the global production. The application of natural feed additives is an external source of aquaculture production due to the ban on antibiotics as a growth promotor as well as their harmful effects on the host, and cost‐effectiveness. Even consumer concerns those antibiotics can cause the water quality and growth instead of growth promoters of natural feed additives to improve the aquaculture production. The role of feed additives is to control the pathogenic microbes, enhance their growth, immune stimulation, and ensure water quality. For these reasons, several types of dietary feed additives are used in the livestock sector, such as essential oil, essential fatty acid, probiotics, prebiotics, symbiotic, and exogenous enzymes, but here, the feed additives of probiotics' most relevant applications in the aquaculture field in terms of modes of action such as strengthening the immune response, competition of binding sites, production of antipathogenic substances, and growth performance competition for nutrition are described. These additives are considered to be useful for their specific medicinal properties and eco‐friendly metabolism in the digestive system. This review describes the role of various feed additives and their relevance to aquaculture production quality.

AimsThe Heart Failure Association of the European Society of Cardiology (HFA‐ESC) proposed a definition of advanced heart failure (HF) that has not been validated, yet. We assessed its prognostic impact in a consecutive series of patients with high‐risk HF.Methods and resultsThe HELP‐HF registry enrolled consecutive patients with HF and at least one high‐risk ‘I NEED HELP’ marker, evaluated at four Italian centres between 1st January 2020 and 30th November 2021. Patients meeting the HFA‐ESC advanced HF definition were compared to patients not meeting this definition. The primary endpoint was the composite of all‐cause mortality or first HF hospitalization. Out of 4753 patients with HF screened, 1149 (24.3%) patients with at least one high‐risk ‘I NEED HELP’ marker were included (mean age 75.1 ± 11.5 years, 67.3% male, median left ventricular ejection fraction [LVEF] 35% [interquartile range 25%–50%]). Among them, 193 (16.8%) patients met the HFA‐ESC advanced HF definition. As compared to others, these patients were younger, had lower LVEF, higher natriuretic peptides and a worse clinical profile. The 1‐year rate of the primary endpoint was 69.3% in patients with advanced HF according to the HFA‐ESC definition versus 41.8% in the others (hazard ratio [HR] 2.23, 95% confidence interval [CI] 1.82–2.74, p < 0.001). The prognostic impact of the HFA‐ESC advanced HF definition was confirmed after multivariable adjustment for relevant covariates (adjusted HR 1.98, 95% CI 1.57–2.50, p < 0.001).ConclusionsThe HFA‐ESC advanced HF definition had a strong prognostic impact in a contemporary, real‐world, multicentre high‐risk cohort of patients with HF.

Published: May 2022

AbstractDual Catalysis has enabled a plethora of novel unconventional transformations that would have been unattainable by either catalyst alone. The enormous potential of dual catalysis hinges on the synergistic activation of two substrates in discrete catalytic cycles without interfering with one another. The last decade had witnessed diverse dual‐catalyst systems focusing mainly on the combination of transition metal catalysis with either one of Lewis acid catalysis, photoredox catalysis, biocatalysis or organocatalysis (i. e., Lewis bases, Brønsted acids and NHC catalysts). In this setting, the scientific community has greatly embraced the integration of amine catalysts with transition metal catalysts. This Review comprehends the reported examples from the past decade on dual amine/transition metal catalysis and discuss the various activation modes for the functionalisation of carbonyl compounds.
Altered prefrontal‐striatal theta‐band oscillatory dynamics underlie working memory deficits in neuropathic pain rats

Published: May 2022

AbstractBackgroundPrelimbic medial prefrontal cortex (PL‐mPFC) and nucleus accumbens core region (NAcc) play an important role in supporting several executive cognitive mechanisms, such as spatial working memory (WM). Recently, this circuit has been also associated with both sensory and affective components of pain. However, it is still unclear whether this circuit is endogenously engaged in neuropathic pain‐related cognitive dysfunctions.MethodsTo answer this question, we induced the expression of halorhodopsin in local PL‐mPFC neurons projecting to NAcc, and then selectively inhibited the terminals of these neurons in the NAcc while recording neural activity during the performance of a delayed non‐match to sample (DNMS) spatial WM task. Within‐subject behavioural performance and PL‐mPFC to NAcc circuit neural activity was assessed after the onset of a persistent rodent neuropathic pain model—spared nerve injury (SNI).ResultsOur results revealed that the induction of the neuropathy reduced WM performance, and altered the interplay between PL‐mPFC and NAcc neurons namely in increasing the functional connectivity from NAcc to PL‐mPFC, particularly in the theta‐band spontaneous oscillations; in addition, these behavioural and functional perturbations were partially reversed by selective optogenetic inhibition of PL‐mPFC neuron terminals into the NAcc during the DNMS task delay‐period, without significant antinociceptive effects.ConclusionsAltogether, these results strongly suggest that the PL‐mPFC excitatory output into the NAcc plays an important role in the deregulation of WM under pain conditions.SignificanceSelective optogenetic inhibition of prefrontal‐striatal microcircuit reverses pain‐related working memory deficits but has no significant impact on pain responses. Neuropathic pain underlies an increase of functional connectivity between the nucleus accumbens core area and the prelimbic medial prefrontal cortex mediated by theta‐band activity.

AbstractAcetobacterium woodii is known to produce mainly acetate from CO2 and H2, but the production of higher value chemicals is desired for the bioeconomy. Using chain‐elongating bacteria, synthetic co‐cultures have the potential to produce longer‐chained products such as caproic acid. In this study, we present first results for a successful autotrophic co‐cultivation of A. woodii mutants and a Clostridium drakei wild‐type strain in a stirred‐tank bioreactor for the production of caproic acid from CO2 and H2 via the intermediate lactic acid. For autotrophic lactate production, a recombinant A. woodii strain with a deleted Lct‐dehydrogenase complex, which is encoded by the lctBCD genes, and an inserted D‐lactate dehydrogenase (LdhD) originating from Leuconostoc mesenteroides, was used. Hydrogen for the process was supplied using an All‐in‐One electrode for in situ water electrolysis. Lactate concentrations as high as 0.5 g L–1 were achieved with the AiO‐electrode, whereas 8.1 g L–1 lactate were produced with direct H2 sparging in a stirred‐tank bioreactor. Hydrogen limitation was identified in the AiO process. However, with cathode surface area enlargement or numbering‐up of the electrode and on‐demand hydrogen generation, this process has great potential for a true carbon‐negative production of value chemicals from CO2.
Comments on “Biosorption of nickel from aqueous solution onto Liagora viscida: Kinetics, isotherm, and thermodynamics”
Authors: Tran Hai Nguyen , Bollinger Jean‐Claude , Lima Eder C. 
Published: May 2022

AbstractIn 2020, Komarabathina and colleagues published the paper above (the original paper). They used the Liagora viscida‐based biosorbent for adsorbing nickel ions from water. Kinetics, isotherm, and thermodynamics are three important components for the correct description of an adsorption process. However, the authors of the original paper introduced several fundamental errors in these three parts. Other important problems in the original paper are inconsistencies between the experimental data and their modeling results, as well as errors in units. Therefore, we present detailed analyses of these mistakes, hoping that this “comment” paper will also be useful to other researchers (especially beginners) to avoid finding such mistakes elsewhere in the future.
Partitioned analysis of soil‐structure interaction for Nuclear Island Buildings
Authors: Chen Shaolin , Lv Hao , Zhou Guoliang 
Published: May 2022

AbstractThe present methods for three‐dimensional time‐domain soil‐structure interaction (SSI) analysis are often uneconomical because they are performed with a single time integration scheme and a single time step, which prohibits their application to large‐scale SSI problems. In this study, a partitioned analysis of SSI (PASSI) is proposed for enhancing SSI computational efficiency. This is accomplished by partitioning the soil‐foundation‐structure system into the soil (foundation) and structure subsystems and implementing the continuity conditions of the displacements and reaction forces at the soil (foundation)‐structure interface in a primal way. A lumped‐mass explicit finite element method and a transmitting artificial boundary are used to model the unbounded soil, the structure is analyzed via the implicit finite element method, and the response of the rigid foundation is calculated through an explicit time integration scheme. The solution is separately advanced over time for each subsystem. Different time steps can be chosen for the explicit and implicit integration schemes, which can greatly improve efficiency. Interaction effects are accounted for by the transmission and synchronization of the coupled state variables. In addition, intrafield and interfield parallel procedures for PASSI are developed, and their theoretical efficiencies are analyzed. A simple example is provided to verify the performance of the partitioned approach with an explicit‐implicit co‐computation and to compare it to the fully explicit approach. Finally, the seismic response analysis of a nuclear power plant is presented to validate the feasibility and efficiency of the intrafield and interfield parallel procedures.

Published: May 2022

SummaryHeteroatom‐doped carbtableons derived from carbonization of highly porous metal organic framework (MOF) nanocrystals have received tremendous attention due to their exceptional surface areas. They can be used as conductive supports for various electrocatalysts. Depending on the synthesis, various MOFs with different coordination structures, morphologies, and porosities can be designed for versatile applications such as gas storage, catalysis, and energy storage systems. In this work, we combine nitrogen‐doped carbon nanoparticles derived from zeolitic imidazolate framework (ZIF‐8) with PEDOT:PSS, a conductive polymer mixture, for highly flexible supercapacitor electrode. The composite film exhibits a 3D interconnected network favorable for fast charge transfer kinetics with a high surface area. This nitrogen‐doped porous carbon‐PEDOT:PSS composite film shows good specific energy of 7.19 Wh kg−1 and good rate performance as well as long cycle life for at least 5000 charge‐discharge cycles.
Recent applications of immunomodulatory biomaterials for disease immunotherapy
Authors: Dai Huaxing , Fan Qin , Wang Chao 
Published: May 2022

AbstractImmunotherapy is used to regulate systemic hyperactivation or hypoactivation to treat various diseases. Biomaterial‐based immunotherapy systems can improve therapeutic effects through targeted drug delivery, immunoengineering, etc. However, the immunomodulatory effects of biomaterials themselves cannot be neglected. In this review, we outline biomaterials with immunomodulatory functions discovered in recent years and their applications in disease treatment. These biomaterials can treat inflammation, tumors, or autoimmune diseases by regulating immune cell function, exerting enzyme‐like activity, neutralizing cytokines, etc. The prospects and challenges of biomaterial‐based modulation of immunotherapy are also discussed.
Lipoxygenase‐catalysed co‐oxidation for sustained production of oxyfunctionalized terpenoids
Authors: Nikolaiczyk Vanessa , Kirschning Andreas , Díaz Edison 
Published: May 2022

AbstractLipoxygenases (LOX) catalyse allylic oxidations and epoxidations of a co‐substrate in the presence of an unsaturated fatty acid containing a 1,4‐pentadiene moiety. One‐ and two‐step enzyme assays were established to verify the role or involvement of LOX in such co‐oxidations. It was shown that LOX is only involved in the formation of reactive hydroperoxides, but not in the oxidation of a co‐substrate, assuming a mechanism involving free peroxy radicals for the latter. Ten mono‐ and sesquiterpenes were used as co‐substrates and the resulting products were analysed by mass spectrometry. A semi‐preparative approach was developed using (+)‐valencene as an example, and the resulting products were isolated by preparative GC and their structures elucidated by NMR spectroscopy.
Modeling and monitoring submerged prehistoric sites during offshore sand dredging and implications for the study of Early Holocene Coastal Occupation of Southern California
Authors: Hildebrand John A. , York Andrew L. 
Published: May 2022

AbstractBeach sand dredging projects off the coast of Southern California provide data for improved understanding of the stratigraphic setting for early Holocene sediments and the potential for offshore buried archaeological materials. Geophysical data, core sediments, and invertebrate fossils allow models to be developed for six borrow sites within drown river valleys off San Diego County. These site‐specific models were tested during dredging operations, and the dredge spoil was monitored for archaeological materials. Two of the borrow sites yielded stone bowls consistent with those found in previous offshore archaeological investigations in this region. These artifacts, however, were determined to come from nearshore and lagoonal sediments, not appropriate for direct occupation, raising questions about both the function of stone bowls and the process that resulted in their deposition. The competing hypotheses presented are that these bowls originated in settlements located adjacent to the lagoons, but were eroded and redeposited into the lagoon during transgression, or that they were part of a fishing toolkit used from boats or in shallow waters within the lagoon. This project illustrates the potential for commercial development projects to yield information on submerged archaeological resources, as well as the challenges.
Genesis of the late‐stage base metal sulfide mineralisation and its relationship with the regional deformation in Ambaji–Deri, South Delhi Terrane, North‐West India

Published: May 2022

Proterozoic stratiform VMS‐type Ambaji–Deri Zn–Pb–Cu deposits in the Aravalli‐Delhi mobile belt of North‐West India are hosted within meta‐sedimentary sequences of the South Delhi Terrane. Several fracture‐filled discordant late‐stage base metal mineralised quartz veins have intruded along with the fractures and foliation at very high Pf (σ2 < Pf < σ1) with typical hydrothermal alteration zones. Temperatures estimated from hydrothermal chlorite vary from 226 to 293°C (mean. 260°C). 40Ar‐39Ar dating of hydrothermal muscovite yielded a plateau age of 625.5 ± 3.3 Ma. Detailed fluid inclusion (FI) analysis reveals three types of primary and four types of secondary FI. Primary H2O‐NaCl‐CO2 ± N2 type 1a FI has medium to high salinity (11.21–21.96 wt% NaCl equivalent) and high density (0.90–1.04 g/cm3), while the secondary type 1b FI with same compositions are characterized by medium salinity (~12.6 wt% NaCl equivalent) and lower density (0.89–0.90 g/cm3). Phase separation/fluid immiscibility is the primary mechanism of mineralisation in the Ambaji–Deri that caused the original fluid to evolve separately as gaseous (CO2) type 2a, b and aqueous type 3a, b (H2O‐NaCl) with similar salinity and density for the aqueous inclusions and low density for the gaseous inclusions (lowering up to 0.58 g/cm3). The ore‐forming fluid with magmatic signatures possibly originated from the cooling G3 granites, remobilized the pre‐existing metals, and precipitated at ~265°C and ~1 kbar at the epizonal depths in the dilated fractures. Later these fluids are mixed with meteoric water and evolved into low saline aqueous fluids that produced supergene alterations.
