The contradictions of 21st century capitalism
Authors: Roberts Michael 
Published: July 2022

In this article, Michael Roberts analyses the economic, environmental, and geopolitical contradictions inherent in the capitalist system from a historical and comparative perspective. According to the economist, the Long Depression in which the world economy has been submerged for decades may end up assuming various forms (recessions, technological revolution, changes in the economic cycle), or through political action that consciously replaces the capitalist social formation. However, the turbulences of the world today could also, as in the imperialist past that preceded the First World War, end in creative destruction through war. In any case, the global threat of climate change, if current trends are not reversed, could even end life as we know it.
En este artículo, Michael Roberts analiza las contradicciones económicas, ambientales y geopolíticas inherentes al sistema capitalista desde una perspectiva histórica y comparativa. Según el economista, la Larga Depresión en la que se encuentra sumergida la economía mundial desde hace décadas puede terminar asumiendo diversas formas (recesiones, revolución tecnológica, cambios en el ciclo económico), o mediante una acción política que reemplace conscientemente la formación social capitalista. Sin embargo, las turbulencias del mundo actual también podrían, como en el pasado imperialista que precedió a la Primera Guerra Mundial, terminar en una destrucción menos creativa a través de la guerra. En cualquier caso, la amenaza global del cambio climático, si no se revierten las tendencias actuales, podría incluso acabar con la vida tal como la conocemos.

AbstractRobust neuromorphic computing in the Big Data era calls for long‐term stable crossbar‐array memory cells; however, the elemental segregation in the switch unit and memory unit that inevitably occurs upon cycling breaks the compositional and structural stability, making the whole memory cell a failure. Searching for a novel material without segregation that can be used for both switch and memory units is the major concern to fabricate robust and reliable nonvolatile cross‐array memory cells. Tellurium (Te) is found recently to be the only peculiar material without segregation for switching, but the memory function has not been demonstrated yet. Herein, apparent piezoelectricity is experimentally confirmed with spontaneous polarization behaviors in elementary 2D Te, even in monolayer tellurene (0.4 nm), due to the highly oriented polarization of the molecular structure and the non‐centrosymmetric lattice structure. A large memory window of 7000, a low working voltage of 2 V, and high on switching current up to 36.6 µA µm−1 are achieved in the as‐fabricated Te‐based memory device, revealing the great promise of Te for both switching and memory units in one cell without segregation. The piezoelectric Te with spontaneous polarization provides a platform to build robust, reliable, and high‐density logic‐in‐memory chips in neuromorphic computing.

AbstractSulfide kesterite Cu2ZnSnS4 (CZTS) solar cells, containing earth‐abundant and environmentally benign constituents, are regarded as promising candidates for thin‐film photovoltaic technologies. CZTS device performance, however, is currently limited by severe nonradiative recombination caused by abundant deep‐level defects. Herein, an effective defect engineering approach for high bandgap CZTS solar cells using a newly introduced moisture‐assisted post‐deposition annealing treatment is reported. This treatment modifies the local chemical composition within the heterojunction and CZTS grain boundaries and enhances the incorporation of Cd within the CZTS layer during CdS deposition. Cd not only accumulates at the grain boundaries, but it also presents in grain interiors where it occupies Cu lattice sites. The overall modification of the local chemical environment suppresses deep level defects and activates relatively shallow acceptor CuZn antisites and Cu vacancies, giving rise to remarkably improved device performance. This work opens a new direction for defect engineering of kesterite materials, which may also be applicable to other thin film semiconductors.
The impact of no‐till crop rotation on dryland soil properties and crop yields
Authors: Sainju Upendra M. 
Published: July 2022

AbstractInformation on the effect of no‐till crop rotation on a broad range of soil properties and long‐term crop yields is needed to evaluate its benefits on ecosystem services compared with monocropping. The objective of this study was to examine the effects of no‐till crop rotation (barley [Hordeum vulgare L.]/spring wheat [Triticum aestivum L.]–pea [Pisum sativum L.]) and monocropping [continuous barley/spring wheat] on 66 dryland soil physical, chemical, biological, and biochemical properties and long‐term crop yields at two dryland farm sites (14‐ and 36‐yr old) in the northern Great Plains. Soil samples collected to a depth of 15 cm in April 2019 were analyzed for soil properties and crop yields determined. At the long‐term site, crop rotation increased 11 properties, but reduced 16 of 66 soil properties compared with monocropping. At the short‐time site, crop rotation increased 6 properties, but reduced 13 of 66 soil properties compared with monocropping. Longer duration experiments showed more differences in soil properties due to crop rotation than shorter duration experiments. Spring wheat and barley yields were greater following pea than following spring wheat or barley during years with normal or above‐average precipitation at both sites. Pea yield in the crop rotation was also greater during these years. Barley/spring wheat–pea rotation can enhance some soil properties and dryland crop yields compared with continuous barley/spring wheat during wet years in the semiarid region of the northern Great Plains.

AbstractAimThe influence of frailty on outcomes after hepatectomy for perihilar cholangiocarcinoma (PHCC) remains unclear. This study aimed to investigate the impact of frailty on the incidence of postoperative complications and survival after major hepatectomy for PHCC.MethodsA total of 87 patients who had undergone surgery for PHCC between 2007 and 2020 were enrolled in this study. Frailty was scored retrospectively using the Clinical Frailty Scale (CFS). The survival and incidence of postoperative complications were compared based on the degree of frailty, and their risk factors were analyzed.ResultsThe overall survival of the CFS score 1‐2 group was significantly higher than that of the CFS score 3‐7 group (P = .01). The survival benefit was especially observed in stage I or II PHCC. Furthermore, there were significant differences between the CFS score 1‐3 group and the CFS score 4‐7 group in the incidence of Clavien–Dindo classification grade ≥ IIIa (39.4% vs 70.6%; P = .03). Frailty was an independent risk factor for severe postoperative complications (odds ratio, 4.11; 95% confidence interval, 1.18‐15.20; P = .03) and the incidence of systemic complications (P < .01).ConclusionFrailty is a predictive factor for short‐ and long‐term outcomes in patients who have undergone major hepatectomy for PHCC.

Published: July 2022

AbstractLithium‐metal batteries (LMBs) capable of operating stably at high temperature application scenarios are highly desirable. Conventional lithium‐ion batteries could only work stably under 60 °C because of the thermal instability of electrolyte at elevated temperature. Here we design and develop a thermal stable electrolyte based on stable solvation structure using multiple ion–dipole interactions. The strong coordination in solvated structure of electrolyte defines the Li deposition behaviour and the evolution of solid electrolyte interphase at high temperature, which is important to achieve high Li Coulombic efficiency and avoid Li dendritic growth. For high mass loading LiFePO4‐Li cells, the cells at 60 °C with conventional electrolyte easily run into failures, but the cells with our electrolyte at 90 °C and 100 °C could cycle more than 120 and 50 cycles respectively. This work provides new insight into electrolyte design and contributes to the development of high temperature LMBs.

ObjectiveSynovial fibrosis contributes to osteoarthritis (OA) pathology, but the underlying mechanisms remain unknown. We have observed increased microRNA‐27b‐3p (miR‐27b‐3p) levels in synovial fluid of patients with late‐stage radiographic knee OA. Here, we investigated the contribution of miR‐27b‐3p to synovial fibrosis in patients with severe knee OA and in a mouse model of knee OA.MethodsWe stained synovium sections obtained from patients with radiographic knee OA scored according to the Kellgren/Lawrence scale and mice that underwent destabilization of the medial meniscus (DMM) for miR‐27b‐3p using in situ hybridization. We examined the effects of intraarticular injection of miR‐27b‐3p mimic into naive mouse knee joints and intraarticular injection of a miR‐27b‐3p inhibitor into mouse knee joints after DMM. We performed transfection with miR‐27b‐3p mimic and miR‐27b‐3p inhibitor in human OA fibroblast‐like synoviocytes (FLS) using reverse transcriptase–quantitative polymerase chain reaction (RT‐qPCR) array, RNA sequencing, RT‐qPCR, Western blotting, immunofluorescence, and migration assays.ResultsWe observed increased miR‐27b‐3p expression in the synovium from patients with knee OA and in mice with DMM‐induced arthritis. Injection of the miR‐27b‐3p mimic in mouse knee joints induced a synovial fibrosis‐like phenotype, increased synovitis scores, and increased COL1A1 and α‐smooth muscle actin (α‐SMA) expression. In the mouse model of DMM‐induced arthritis, injection of the miR‐27b‐3p inhibitor decreased α‐SMA but did not change COL1A1 expression levels or synovitis scores. Transfection with the miR‐27b‐3p mimic in human OA FLS induced profibrotic responses, including increased migration and expression of key extracellular matrix (ECM) genes, but transfection with the miR‐27b‐3p inhibitor had the opposite effects. RNA sequencing identified a PPARG/ADAMTS8 signaling axis regulated by miR‐27b‐3p in OA FLS. Human OA FLS transfected with miR‐27b‐3p mimic and then treated with the PPARG agonist rosiglitazone or with ADAMTS8 small interfering RNA exhibited altered expression of select ECM genes.ConclusionOur findings demonstrate that miR‐27b‐3p has a key role in ECM regulation associated with synovial fibrosis during OA.

Published: July 2022

AbstractBurns are the most common and devastating form of wounds and are usually accompanied by abnormal inflammation, inadequate extracellular matrix production, reduced angiogenesis, and lack of growth factor stimulation, which can significantly delay wound healing and lead to complications. Pearl powder, a traditional Chinese medicine, has been used to treat wound healing. In the present study, we found that supercritical CO2 extracted pearl peptides in the size range of “>10kd” have great potential to promote wound healing at the cellular level. Antioxidant hydrogels were designed using selenium‐containing block‐functionalized PEG/PPG polymers. Pearl peptide components were combined into polymeric materials to develop new promising wound dressings. It was shown that pearl peptide hydrogels increased skin fibroblast viability, enhanced cellular resistance to oxidative stress, enhanced tissue remodeling, promoted angiogenesis, and exhibited enhanced promotion in wound healing.

AbstractThis study directly compared the data obtained from coupon studies and flow‐through pipe rack studies from two sources in the Denver Water system. The pipe rack study was completed over multiple years using harvested lead service lines. The coupon studies were completed in about 2 months using pure lead coupons. Orthophosphate at 2 mg/L was found to reduce lead concentrations by about 81% in the pipe racks, whereas 74%–81% was observed in the coupons. At an orthophosphate dose of 1 mg/L lead concentrations were reduced by 62%–65% in the pipe loop and by 55%–75% in the coupons, pH at 8.8 reduced lead by 45%–60% in the pipe racks and by 27%–48% in the coupons. The pipe racks were able to give insights into the transition from one condition to another, which is time‐based and dependent on existing pipe scales. Both types of demonstration studies produced similar conclusions about treatment options. The pipe rack was more representative of conditions in the distribution system while the coupon studies were performed in a fraction of the time.

Published: July 2022

AbstractAmong ‘beyond lithium ion’ energy storage, lithium sulfur (Li−S) batteries are one of the most promising technologies, as a result of the potential for high theoretical energy capacity at low cost. A key obstacle in exploiting the vast potential of Li−S batteries is the formation of soluble polysulfide species. Here, we report sulfurized polypropylene (S/PP‐500) synthesized in one‐step by reacting polypropylene (PP) with sulfur as a new polysulfide shuttle‐free cathode material for Li−S batteries. It exhibits a reversible capacity as high as 1000 mAh/gsulfur at 0.1 C and a sulfur loading of up to 68 wt%, which in turn allows for high sulfur loadings up to 47 % in the final cathode. The low‐cost starting materials together with the simple synthetic procedure and the good electrochemical performance in combination with a commercially available eslectrolyte make the S/PP‐500 a very promising cathode material for Li‐S batteries.

AbstractIn this study, we combined network pharmacology, chromatographic fingerprinting and multicomponent quantitative analysis to evaluate the quality of Moutan Cortex (MC). Specifically, through network pharmacology, we obtained a comprehensive understanding of the active components and pharmacological activities of MC. In addition, the method of establishing fingerprint and multicomponent quantification by ultra high‐performance liquid chromatography is convenient and comprehensive, and can more fully reflect the overall distribution of various chemical components. Principal component analysis and discriminant least square analysis were used. The results show that MC plays a synergistic role through multiple targets and pathways. The contents of chemical components in MC from different sources were significantly different. Combining network pharmacology and multicomponent quantitative results, gallic acid, benzoyl paeonol, paeonol, methyl gallate, benzoic acid and paeonol can be used as quality markers for MC quality control. This study provides a comprehensive and reliable strategy for the quality evaluation of MC and determines its quality indicators to ensure the quality of Chinese herbal medicine.

Published: July 2022

AbstractTo remove H2S and HCN from acid gases, wet‐oxidative desulfurization such as the Takahax process can be applied. There, a continuous wastewater stream with high concentrations of ammonium thiosulfate and thiocyanate is discharged. By wet air oxidation of these salts at 473–573 K, fertilizer‐grade ammonium sulfate can be obtained. Thiosulfate wet air oxidation kinetics was investigated under industrially relevant conditions via the oxygen consumption rate in a high‐pressure reactor. Kinetic parameters were estimated with a dynamic reactor model. The experimental data was reproduced with a good average deviation of 2.17 %, and the applied reaction pathway is simple due to the high temperatures. This is an important step towards taylor‐made reactors for wet air oxidation of Takahax wastewater.
