A Review on Minimization of Polysulfide Shuttle Effect of Lithium–Sulfur Batteries by Using Low‐Dimensional Carbon Composite as the Sulfur Cathode

Owing to the high specific energy density in theories, abundance of resources, and adherence to environmental standards, rechargeable lithium–sulfur batteries (LSB) have drawn an increasing amount of interest. However, the weak conductivity of the sulfur and discharge products, the drastic breakdown and migration of the intermediates of lithium polysulfide (LiPSs) leading to shuttle effect, and the enormous volumetric change of sulfur particles upon cycle substantially hinder their practical uses. Due to the considerable capacity diminishing caused by the shuttle impact corrosion of the lithium metal, LSBs are thought to have significant commercial application challenges. Engineering nanomaterials’ surface structures can increase the affinity between the cathode with the LiPSs while also enabling the redox kinetics of the LiPSs, which results in a low level of LiPSs in the electrolyte that can restrict the shuttle effect. Sulfur and carbon materials, when combined, effectively increase the efficiency of active materials, increase the conductive properties of cathode components, and serve as a barrier against polysulfides. In this review, a thorough analysis is provided on low‐dimensional carbon materials as cathode, by which the electrode modification technique for limiting the shuttle effect of polysulfide in LSBs and forecast future research trends on the same.

REASSURED Test System for Food Control—Preparation of LAMP Reaction Mixtures for In-Field Identification of Plant and Animal Species

The potential of loop-mediated isothermal amplification (LAMP) assays for species identification in medical diagnostics, food safety, and authentication is indisputable. The challenge in commercialization of such DNA-based rapid test methods for resource-limited settings is the on-site availability of the required reagents and an intuitive read-out system. In this work, reaction mixtures for LAMP assays for the detection of animal (plaice) and plant food (safflower) were lyophilized and stored at room temperature for up to 24 weeks, demonstrating that refrigeration of reagents after lyophilization is not absolutely necessary. During this period, reaction mixtures were stable and the polymerase showed no loss of activity. In addition, mobile testing, including DNA isolation, using the lyophilized LAMP reaction mixtures and a handheld fluorescence detection read-out system (Doctor Vida Pocket test) was successfully performed outside of the laboratory environment in less than 40 min using a proposed standard operation procedure. The results highlight that the use of the lyophilized LAMP reaction for food control purposes has the potential to meet the WHO-proposed REASSURED criteria.

Regulation of coordinated nitrogen species for atomically dispersed Fe-N5 catalyst to boost electrocatalytic CO2-to-CO conversion

Single atom Fe catalysts coordinated with five N atoms (Fe-N5) have been adopted for excellent CO2-to-CO conversion. However, Fe-N5 catalysts typically face trade-offs among Faradaic efficiency (FE), current density, and stability, posing challenges for further commercialization. Additionally, the role of coordinated N species in their catalytic activities remains unclear. Herein, Fe-N5 catalysts coordinated with a high abundance of pyridinic-N (Fe-N5-pyri) or pyrrolic-N (Fe-N5-pyrro) are synthesized. Both operando experiment results and theoretical calculation manifest that pyrrolic-N increases CO2 adsorption capacity, reduces the reaction free energies required for CO2 activation, and facilitates *CO desorption by weakening the bonding strength with reaction centers. As a result, Fe-N5-pyrro exhibits superior CO2-to-CO conversion performance, achieving a maximum FECO of 96.6% and a partial current density exceeding –130mAcm-2 in 0.5M KHCO3, maintaining stable operation for over 100h. This work highlights the role of nitrogen species in Fe-N5 catalysts and provides a promising strategy for synthesizing robust catalyst for CO2 electrochemical reduction.

Improving functionality and metabolite profiles of black sapote juice through lactic acid bacteria fermentation

Black sapote, a tropical fruit rich in vitamins and bioactive compounds, is known for its high antioxidant activity. However, its rapid deterioration during postripening poses challenges for transportation and commercialization. Although lactic acid bacterial (LAB) fermentation is widely used to increase the nutritional content and shelf-life of various foods, its application to black sapote juice (BSJ) has not been explored until now. This study investigated the impact of LAB strains (Lactococcus cremoris, Lacticaseibacillus rhamnosus, and Limosilactobacillus reuteri) on the quality of BSJ. These results demonstrate that BSJ is an excellent substrate for LAB proliferation. Fermentation significantly altered the sugar and acid contents and notably increased the concentrations of phytochemicals and antioxidant activity. The ABTS radical scavenging activity of L. rhamnosus increased by 76%, and its total phenolic content improved by 35%. Furthermore, volatile compound and metabolomic profiling analyses indicated that fermentation significantly increased the relative abundances of benzaldehyde, linalool, ascorbic acid, and caffeic acid and generated novel compounds such as acetoin. Therefore, LAB fermentation markedly altered both the flavor profile and metabolic characteristics of BSJ, influencing multiple metabolic pathways. These findings open new avenues for BSJ processing, positioning it as a promising candidate for the development of innovative functional foods.

Oral Administration of Zinc Sulfate with Intramuscular Foot-and-Mouth Disease Vaccine Enhances Mucosal and Systemic Immunity.

Background/Objectives: Foot-and-mouth disease (FMD) remains a significant global threat to livestock farming. Current commercial FMD vaccines present several challenges, including the risk of infection and adverse injection site reactions due to oil-based adjuvants. The complex immune environment of the gut-associated lymphoid tissue has the potential to induce broad and diverse immune responses. Therefore, we aimed to explore the potential of zinc sulfate as an oral adjuvant to enhance intestinal mucosal immunity and complement the effects of intramuscular (IM) FMD vaccination. Methods: We conducted serological analyses on mice and pigs, measuring secretory IgA (sIgA) levels and evaluating the expression of mucosal immunity-related genes in pigs. These assessments were used to investigate the systemic and mucosal immune responses induced by oral zinc sulfate administration in combination with an IM FMD vaccine. Results: This combination strategy significantly increased structural protein antibody titers and virus neutralization titers in experimental animals (mice) and target animals (pigs) across early, mid-, and long-term periods. Additionally, this approach enhanced the expression of key cytokines associated with mucosal immunity and increased sIgA levels, which are critical markers of mucosal immunity. Conclusions: Oral zinc sulfate administration may synergize with inactivated FMD vaccines, leading to sustained and enhanced long-term immune responses. This novel strategy could reduce the frequency of required vaccinations or allow for a lower antigen dose in vaccines, effectively stimulating the mucosal immune system and boosting systemic immunity. This approach has the potential to improve the overall efficacy of commercial FMD vaccines.

About two-third (67.7%) had good aggregate knowledge score and more than half (57.4%) of the study participant had good uptake and utilization of HIV/AIDs preventive services. After adjusting for the confounding effects using logistic regression analysis; educational status of secondary school (AOR=2.25, 95% CI=1.21–13.25) and post-secondary (AOR=4.10,95%CI=2.22-17.88), monthly income of between N50,0001 – N100,000.00 (AOR=2.02, 95%CI=1.74-19.33) and >N100,000.00 (AOR=4.01, 95%CI=3.11-27.33), working experience of 11 – 20 years (AOR=3.25, 95%CI= 1.16-22.56) and >20 years (AOR=6.05, 95%CI= 3.03-26.77) and good aggregate knowledge scores on HIV/AIDs preventive measures (AOR=4.02 (2.13 – 14.55), 95%CI=2.13-14.55) remained significant predictors of uptake/utilization of HIV/AIDs preventive measures. Conclusion: All agencies responsible for HIV/AIDs control and their partners should take appropriate measures including various strategies to educate this occupational group on sexuality and reproductive health. Also, the establishment of STI clinics in strategic locations, as well as making condoms available, accessible, affordable, and acceptable for use by this group of people in our society, should all be part of the prevention strategy.

Assessment of the Risk of Crack Formation at a Hybrid Bonding Interface Using Numerical Analysis.

Hybrid bonding technology has recently emerged as a promising solution for advanced semiconductor packaging technologies. However, several reliability issues still pose challenges for commercialization. In this study, we investigated the possibility of crack formation caused by chemical mechanical polishing (CMP) defects and the misalignment of the hybrid bonding structure. Crack formation and thermomechanical stress were analyzed for two common hybrid bonding structures with misalignment using a numerical simulation. The effects of annealing temperature and dishing value on changes in the non-bonding area and peeling stress were systematically analyzed. The calculated peeling stresses were compared to the bonding strength of each bonding interface to find vulnerable regions prone to cracking. The non-bonding area in the bonding structure increased with a decreasing annealing temperature and an increasing dishing value. To achieve a sufficient bonding area of more than 90%, the annealing temperature should be greater than 200 °C. During the heating period of the annealing process, the SiCN-to-SiCN bonding interface was the most vulnerable cracking site with the highest peeling stress. An annealing temperature of 350 °C carries a significant risk of cracking. On the other hand, an annealing temperature lower than 250 °C will minimize the chance of cracking. The SiCN-to-SiO2 bonding interface, which has the lowest adhesion energy and a large coefficient of thermal expansion (CTE) mismatch, was expected to be another possible cracking site. During cooling, the SiCN-to-Cu bonding interface was the most vulnerable site with the highest stress. However, the simulated peeling stresses were lower than the adhesion strength of the bonded interface, indicating that the chance of cracking during the cooling process was very low. This study provides insights into minimizing the non-bonding area and preventing crack formation, thereby enhancing the reliability of hybrid bonding structures.

Iron-Ore Reduction in Fluidized Beds: Review of Commercial Technologies, Status, and Challenges

Evaluating the Effectiveness of the Biodegradable Superabsorbent Polymer (Fasal Amrit) on Soil Hydrological Properties: A Laboratory Rainfall Simulation Study

Superabsorbent polymers (SAPs) are effective soil amendments that can control soil erosion by improving soil quality. However, many commercial SAPs face challenges including limited biodegradability, high costs, and adverse effects on soil hydrological properties, which can lead to increased water and soil loss. This study examined the potential of lower dosages of biodegradable SAPs to improve the hydrological properties of “Shimajiri-maji” (clay) soil. Three concentrations of biodegradable Fasal Amrit polymer (EFP) (P1: 0, P2: 3 g m−2, and P3: 6 g m−2) were evaluated under three simulated rainfall intensities (I1: 35; I2: 70 and I3: 110 mm h−1) and two gradients (7.5%, and 15%) during consecutive storms. The time to generate runoff, infiltration, runoff, soil loss, and water storage (WS) were quantified over one hour. The results show that runoff generation was delayed in EFP-treated soils compared to the control. Both polymer treatments enhanced infiltration (P2 > P3 > P1) and reduced runoff and soil loss (P2 < P3 < P1). Higher EFP rates improved water storage at surface depths (P3 > P2 > P1). EFP-treated soils exhibited lower interrill erodibility, suggesting greater resistance to soil erosion compared to the control. EFP treatments also significantly improved the soil’s physical properties (bulk density, porosity, organic matter, aggregate stability). EFPs can diminish runoff and soil loss as the EFP-treated plots exhibited greater aggregate stability than the control. It was concluded that low EFP concentrations can improve soil hydrological properties and mitigate soil erosion. Further investigations are needed to optimize the EFP concentrations for different soil types.

Application Evaluation and Performance-Directed Improvement of the Native and Engineered Biosensors.

Transcription factor (TF)-based biosensors (TFBs) have received considerable attention in various fields due to their capability of converting biosignals, such as molecule concentrations, into analyzable signals, thereby bypassing the dependence on time-consuming and laborious detection techniques. Natural TFs are evolutionarily optimized to maintain microbial survival and metabolic balance rather than for laboratory scenarios. As a result, native TFBs often exhibit poor performance, such as low specificity, narrow dynamic range, and limited sensitivity, hindering their application in laboratory and industrial settings. This work analyzes four types of regulatory mechanisms underlying TFBs and outlines strategies for constructing efficient sensing systems. Recent advances in TFBs across various usage scenarios are reviewed with a particular focus on the challenges of commercialization. The systematic improvement of TFB performance by modifying the constituent elements is thoroughly discussed. Additionally, we propose future directions of TFBs for developing rapid-responsive biosensors and addressing the challenge of application isolation. Furthermore, we look to the potential of artificial intelligence (AI) technologies and various models for programming TFB genetic circuits. This review sheds light on technical suggestions and fundamental instructions for constructing and engineering TFBs to promote their broader applications in Industry 4.0, including smart biomanufacturing, environmental and food contaminants detection, and medical science.

FeS2/SnS2@C with mosaic-like heterointerface as robust sodium anode

Sodium-ion batteries (SIBs) have been widely researched due to their abundant resource and inherent safety. However, the major challenge for further commercialization of SIBs is the absence of low-priced anode electrodes with high reversible capacity and durability. Herein, a hierarchical heterogeneous structure of FeS2/SnS2@C nanocubes with rich two-dimensional mosaic-like heterointerface and N/S co-doped carbon wrapping is constructed and synthesized, to achieve ultrahigh reversible capacity and long cycling stability as anode of SIBs. Combining x-ray photoelectron spectroscopy, ion diffusion kinetic analysis, and in situ x-ray diffraction, the exquisite hierarchical heterogeneous structure of FeS2/SnS2@C could promote charge/electrons transfer and accelerate ion diffusion kinetics. As expected, the FeS2/SnS2@C anode shows superior reversible capacity (867.5 mA h g−1 at 0.1 A g−1), good rate performance (718.9 mA h g−1 at 5.0 A g−1), and long cycle stability (738.0 mA h g−1 after 1200 cycles at 5.0 A g−1) with Na metal as counter electrode. This work proves that the effectiveness of heterojunction interfaces for promoting Na+ diffusion is highlighted by such capabilities.

Lithiophilic Reduced Graphene Oxide/Carbonized Zeolite Imidazolate Framework-8 Composite Host for Stable Li Metal Anodes.

Lithium (Li) metal is regarded as a next-generation anode material owing to its high energy density. However, issues such as dendritic growth and volume changes during charging and discharging pose significant challenges for commercialization. We propose using lithiophilic reduced graphene oxide (rGO) and carbonized zeolite imidazolate framework-8 (C-ZIF-8) composites as host materials for Li to address these problems. The rGO/C-ZIF-8 composites are synthesized through a simple redox reaction followed by carbonization and are characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS). The roles of chemical composition, characteristics, and morphology are demonstrated. As a result of these favorable structural and functional properties, the Li symmetric cell with rGO/C-ZIF-8 exhibits a stable voltage profile for more than 100 h at 1 mA cm-2 without short-circuiting. A relatively low Li plating/stripping overpotential of ~101.5 mV at a high current density of 10 mA cm-2 is confirmed. Moreover, a rGO/C-ZIF-8-Li full cell paired with a LiFePO4 cathode demonstrates good cyclability and rate capability.

Cerium rare-earth ions reinforced built-in electric field to enable efficient carrier extraction for highly efficient and stable perovskite solar cells

Perovskite solar cells prepared by inorganic-organic three-dimensional hybrid have good power conversion efficiency, but their operational stability remains a major challenge for commercialization. The defect of perovskite is an important factor restricting its charge dynamics and stability. Here, the rare earth metal chloride CeCl3 is introduced into perovskite solution to passivate the defects, where the Pb2+ part of the B position is replaced by Ce3+. The prepared films have the characteristics of increasing grain size, enhancing carrier mobility and excellent crystallinity. Meanwhile, via passivating interface defects and improving carrier transport capacity, the generation of non-radiative recombination is reduced, the carrier migration length is extended, and the device performance is improved. The results show that the PCE of the standard device is only 65 % after 2880 h of N2 atmosphere at room temperature, while the efficiency of the device doped with CeCl3 can remain at 93 %. When the unencapsulated sample was placed in an air environment (40–60 % humidity), the control sample was reduced to 72 % at 1060 h, while the CeCl3 was maintained at 87 %. Additionally, the reduction of residual stress in the perovskite layer also provides good bending stability for the flexible target device. These results show that the incorporation of rare earth metal ions is an effective way to stabilize and improve the efficiency of the device.
