The organic amendment of degraded soil in South East of Tunisia was used to restore the chemical, and physical properties of soil quality investigated in this study. Biochar derived from pyrolyzed green waste at 360°C was used like organic amendment. Nines randomized plots with one square meter of the area of each plot in three replicates have been installed in the Institute of Arid Area in Mednine South East of Tunisia, with two rates of biochar 20 and 40 t/ha were investigated: 20 tons/ha (B20) (2 kg/m²) and 40 tons/ha (B40) (4 kg/m²). The results showed that biochar had a positive effect on soil's physical and chemical properties compared to non-amended soil (Untreated soil). Biochar supply at rates of 20 and 40 tons/ha, causes a decrease in electrical conductivity to achieve 2.66 mS/cm for the B40 dose after 1 year of amendment, also a decrease in the bulk density at the surface layer (0-20 cm) has been registered, the total porosity which was decreased with depth. The hydraulic conductivity is favored by the incorporation of biochar in the soil which increases the volume of voids and tends to create preferential flow paths.

CPUE standardization for southern bluefin tuna (Thunnus maccoyii) in the Korean tuna longline fishery, accounting for spatiotemporal variation in targeting through data exploration and clustering
Authors: Hoyle Simon D. , Lee Sung Il , Kim Doo Nam 
Published: September 2022

Accounting for spatial and temporal variation in targeting is a concern in many catch per unit effort (CPUE) standardization exercises. In this study we standardized southern bluefin tuna (Thunnus maccoyii, SBT) CPUE from the Korean tuna longline fishery (1996–2018) using generalized linear models (GLMs) with operational set by set data. Data were first explored to investigate the operational characteristics of Korean tuna longline vessels fishing for SBT, such as the spatial and temporal distributions of effort, and changes in the nominal catch rates among major species and species composition. Then we estimated SBT CPUE by area used for the stock assessment in the CCSBT (Commission for the Conservation of Southern Bluefin Tuna) and identified two separate areas in which Korean tuna longline vessels have targeted SBT and albacore tuna (T. alalunga), with targeting patterns varying spatially, seasonally and longer term. We applied two approaches, data selection and cluster analysis of species composition, and compared their ability to address concerns about the changing patterns of targeting through time. Explanatory variables for the GLM analyses were year, month, vessel identifier, fishing location (5° cell), number of hooks, moon phase, and cluster. GLM results for each area suggested that location, year, targeting, and month effects were the principal factors affecting the nominal CPUE. The standardized CPUEs for both areas decreased until the mid-2000s and have shown an increasing trend since that time.

Published: September 2022

This paper assesses the restoration process (before and after) of "The Serious Learner”, an outdoor concrete statue found at the forecourt of Oduro block, Takoradi Technical University (TTU)-Ghana. Direct observations and unstructured interviews under the qualitative research method were employed to elicit data from respondents such as art lecturers and students of the Sculpture Department, TTU. Data were analyzed using archival studies, descriptive and visual analysis tools with a studio-based process. The study revealed that "The Serious Learner" outdoor concrete statue formed an integral element of landscaping at the Oduro block, TTU. However, significant features such as the pedestal, body parts, lighting system and finishes of the outdoor statue have deteriorated due to weathering and had received no restoration since its erection. Repairs and management of artefacts in public space, not only in TTU, should be performed every two years to ensure their longevity and posterity as conservation and restoration method is significant in outdoor sculptures.

Published: September 2022

AbstractConstructing high‐performance‐2D heterostructures and deciphering the underlying microscopic mechanism of carrier dynamics are crucial in optoelectronic and photovoltaic applications. Here, taking black phosphorus (BP)/MoS2 heterostructure with type‐II band alignment as a prototypical example, the ab initio nonadiabatic molecular dynamics simulations demonstrate that the interlayer carrier dynamics are thickness dependent. Specifically, the electron transfer from a monolayer (1L)‐BP to MoS2 occurs quickly within 54 fs. In contrast, hole transfer can only be observed within 1 ps with BP's layer number N ≥ 2, triggered by the excitation of low‐frequency acoustic phonon and interlayer shear and breathing phonon modes within 100 cm–1 that enhances the interlayer coupling. Particularly, the electron and hole transfer time exhibits respectively linear and exponential dependence on the layer number N of BP component. The present findings shed new light on improving the process of ultrafast carrier dynamics of 2D heterostructures for photoconversion.
A Liquid–Solid Contact Electrification Based All‐Optical Liquid Flow Sensor for Microfluidic Analysis in Biomedical Applications
Authors: Su Li , Xiong Quan , Zhu Yuyan , Zi Yunlong 
Published: September 2022

AbstractLiquid flow sensor is an important component of the microfluidic system for analytical science and biomedical systems. However, traditional microfluidic systems are complex in structure, costly, bulky, and generate environmental pollutants. Herein, a novel and high‐performance self‐powered all‐optical liquid flow sensor (ALFS) based on triboelectrification‐induced electroluminescence (TIEL) is proposed. The TIEL signal is self‐generated in real time through contact electrification between a polymer–fluid–air surface and moving fluid. Moreover, the amplitude and time span of the electric field can be swiftly altered by adjusting the bottom grid electrode layer with an appropriate geometric design, so that a high sensitivity of 0.089 s mm–1 and an extremely low flow velocity limit of 1 mm s–1 can be achieved. The velocity, volume, and composition of the liquid flow can be obtained either by observation or through optical information extraction from data analysis software. Furthermore, the ALFS can be incorporated into an infusion monitor and a microfluidic chip for biomedical applications. This study proposes not only an innovative method for liquid flow monitoring but also a new rationale of coupling triboelectrification into the microfluidic system design, which potentially has a wide range of applications in the medical, biological, and industrial fields.

Published: September 2022

AbstractCancer immunotherapy is restricted to immune resistance caused by immunosuppressive tumor microenvironment. Pyroptosis involved in antitumor immunotherapy as a new schedule is prospective to reverse immunosuppression. Herein, acidic tumor microenvironment (TME)‐evoked MRC nanoparticles (MRC NPs) co‐delivering immune agonist RGX‐104 and photosensitizer chlorine e6 (Ce6) are reported for pyroptosis‐mediated immunotherapy. RGX‐104 remodels TME by transcriptional activation of ApoE to regress myeloid‐derived suppressor cells' (MDSCs) activity, which neatly creates foreshadowing for intensifying pyroptosis. Considering Ce6‐triggered photodynamic therapy (PDT) can strengthen oxidative stress and organelles destruction to increase immunogenicity, immunomodulatory‐photodynamic MRC nanodrugs will implement an aforementioned two‐pronged strategy to enhance gasdermin E (GSDME)‐dependent pyroptosis. RNA‐seq analysis of MRC at the cellular level is introduced to first elucidate the intimate relationship between RGX‐104 acting on LXR/ApoE axis and pyroptosis, where RGX‐104 provides the prerequisite for pyroptosis participating in antitumor therapy. Briefly, MRC with favorable biocompatibility tackles the obstacle of hydrophobic drugs delivery, and becomes a powerful pyroptosis inducer to reinforce immune efficacy. MRC‐elicited pyroptosis in combination with anti‐PD‐1 blockade therapy boosts immune response in solid tumors, successfully arresting invasive metastasis and extending survival based on remarkable antitumor immunity. MRC may initiate a new window for immuno‐photo pyroptosis stimulators augmenting pyroptosis‐based immunotherapy.

AbstractEndothelialization of vascular implants plays a vital role in maintaining the long‐term vascular patency. In situ endothelialization and re‐endothelialization is generally achieved by selectively promoting endothelial cell (EC) adhesion and, meanwhile, suppressing smooth muscle cell (SMC) adhesion. Currently, such EC versus SMC selectivity is achieved and extensively used in vascular‐related biomaterials utilizing extracellular‐matrix‐derived EC‐selective peptides, dominantly REDV and YIGSR. Nevertheless, the application of EC‐selective peptides is limited due to their easy proteolysis, time‐consuming synthesis, and expensiveness. To address these limitations, a polymeric strategy in designing and finding EC‐selective biomaterials using amphiphilic β‐peptide polymers by tuning serum protein adsorption is reported. The optimal β‐peptide polymer displays EC versus SMC selectivity even superior to EC‐selective REDV peptide regarding cell adhesion, proliferation, and migration of ECs versus SMCs. Study of the mechanism indicates that surface adsorption of bovine serum albumin, an abundant and anti‐adhesive serum protein, plays a critical role in the ECs versus SMCs selectivity of β‐peptide polymer. In addition, surface modification of the optimal β‐peptide polymer effectively promotes the endothelialization of vascular implants and inhibits intimal hyperplasia. This study provides an alternative strategy in designing and finding EC‐selective biomaterials, implying great potential in the vascular‐related biomaterial study and application.

AbstractNonradiative losses caused by defects are the main obstacles to further advancing the efficiency and stability of perovskite solar cells (PSCs). There is focused research to boost the device performance by reducing the number of defects and deactivating defects; however, little attention is paid to the defect‐capture capacity. Here, upon systematically examining the defect‐capture capacity, highly polarized fluorinated species are designed to modulate the dielectric properties of the perovskite material to minimize its defect‐capture radius. On the one hand, fluorinated polar species strengthen the defect dielectric‐screening effect via enhancing the dielectric constant of the perovskite film, thus reducing the defect‐capture radius. On the other, the fluorinated iodized salt replenishes the I‐vacancy defects at the surface, hence lowering the defect density. Consequently, the power‐conversion efficiency of an all‐inorganic CsPbI3 PSC is increased to as high as 20.5% with an open‐circuit voltage of 1.2 V and a fill factor of 82.87%, all of which are among the highest in their respective categories. Furthermore, the fluorinated species modification also produces a hydrophobic umbrella yielding significantly improved humidity tolerance, and hence long‐term stability. The present strategy provides a general approach to effectually regulate the defect‐capture radius, thus enhancing the optoelectronic performance.

Published: September 2022

AbstractCO2 conversion to added value products using green processes in terms of source of energy, energy consumption, and/or management of raw materials obtained from waste materials are very attractive approaches for a modern sustainable society. In this work, such approaches are integrated, converting CO2 into ethanol by using polluted air as feeding gas. More specifically, recycled permanently polarized hydroxyapatite catalysts are prepared by applying a thermally stimulated polarization process to pork, beef, and chicken scrapped bones. The recycled bone catalysts are used to perform a series of reactions fed with polluted air and only powered with solar energy using a solar furnace. Reactions are conducted for 5 days and 1 month. Results demonstrate significant decarbonization, converting CO2 into valuable chemical products with high selectivity toward ethanol (up to 99.6%).

Published: September 2022

AbstractThe aqueous electrochemical CO2 reduction to valuable products is seen as one of the most promising candidates to achieve carbon neutrality yet still suffers from poor selectivity and lower current density. Highly efficient CO2 reduction significantly relies on well‐constructed electrode to realize efficient and stable triple‐phase contact of CO2, electrolyte, and active sites. Herein, a triple‐phase interface engineering approach featuring the combination of hierarchical porous morphology design and surface modification is presented. A hierarchical porous electrode is constructed by depositing bismuth nanosheet array on copper foam followed by trimethoxy (1H,1H,2H,2H‐heptadecafluorodecyl) silane modification on the nanosheet surface. This electrode not only achieves highly selective and efficient CO2 reduction performance with formate selectivity above 90% over wide potentials and a partial current density over −90 mA cm−2 in H‐cell but also maintains a superior stability during the long‐term operation. It is demonstrated that this remarkable performance is attributed to the construction of efficient and stable triple‐phase interface. Theoretical calculations also show that the modified surface optimizes the activation path by lowering thermodynamic barriers of the key intermediates *OCHO for the formation of formate during electrochemical CO2 reduction.

AbstractThe application of renewable energy conversion devices is considered as one of the effective ways to alleviate the energy shortage and environmental pollution. Designing electrocatalysts with excellent performance and affordable price is promising to accelerate the reaction process and large‐scale application. At present, ruthenium (Ru)‐based nanomaterials have shown similar catalytic activity but superior price demand compared to commercial Pt/C. This undoubtedly makes Ru‐based nanomaterials a perfect candidate to replace advanced Pt catalysts. Significant progress is made in the rational design of Ru‐based electrocatalysts, but an in‐depth understanding of the engineering strategies and induced effects is still at an early stage. This review summarizes the modification strategies for enhancing the catalytic activity of Ru, including surface structure, metal element, nonmetal element, size, bimetallic oxides, and heterostructure engineering strategies. Then the induced electronic modulation effects generated by the intramolecular and intermolecular of the Ru‐based nanomaterials are elucidated. Further, the application progress of engineered Ru‐based nanomaterials for hydrogen and oxygen conversion reactions is highlighted, and the correlations of engineering strategies, catalytic activity, and reaction pathways are elaborated. Finally, challenges and prospects are presented for the future development and practical application of Ru‐based nanomaterials.
