AbstractCreating environmentally friendly materials like polymer matrix composites (PMCs) enhanced with natural fillers has grown in recent decades. It supports the United Nations sustainable development goals (SDGs) by reducing the reliance on non‐renewable resources, minimizing waste generation, and promoting sustainable land and water management practices. This investigation assesses the viability of employing Elaeocarpus ganitrus (rudraksha) seeds as a filler (rudraksha seed filler [RSF] in environmentally sustainable composite materials. Various loading concentrations and sizes of RSFs were incorporated by hand lay‐up into polymer epoxy resin (ER). The effect of filler on the mechanical properties of composites was observed. Thermal properties of RSF/epoxy composites were investigated using thermogravimetric analysis (TGA) and Fourier transform infrared (FTIR). The 10 wt% 100‐mesh filler had the maximum tensile strength (TS) at 42.30 MPa and flexural strength (FS) at 87.4 MPa, surpassing other filler sizes and loading concentrations. Meanwhile, the highest impact properties have been achieved with 20 wt% of RSF with 0.436 J. The results of this study highlight the significant impact of filler type and concentration on the mechanical properties of the material. These findings offer valuable insights that may be applied to various industrial contexts. Furthermore, incorporating 10% up to 30 wt% RSF in epoxy composites has brought more thermal stability than virgin epoxy. It revealed that the RSFs possess higher decomposition temperatures than the epoxy matrix. RSF has a potential sustainable reinforcement in polymer composites and holds great promise for addressing environmental challenges and aligning with several SDGs.Highlights

AbstractPost‐industrial low‐density and linear low‐density polyethylene blown films are mechanically recycled for reutilizing in the production of blown films for packaging applications. This process enables the production of films with lower cost and similar properties while preserving the environment and lowering the amount of waste material disposed of. The mechanical recycling process results in the production of recycled pellets. This process includes chopping, washing, drying, and reprocessing. Mixtures of these recycled materials and their virgin form with various concentrations are shaped into blown films with inherent 70 and 30 wt% loadings for low‐density polyethylene and linear low‐density polyethylene components, respectively. Fourier transform infrared spectroscopy results of the recycled material show no contamination or chemical reaction with other materials. Gel permeation chromatography is carried out on the virgin and recycled low‐density polyethylene and linear low‐density polyethylene, and the results indicate the occurrence of chain session and crosslinking during the recycling process. The decline in the thermal properties of the samples, seen from the differential scanning calorimetry results, indicates the presence of crosslinks. The effect of structural changes caused by the recycling process on the rheological properties is studied. The miscibility of the blend components is evaluated by Cole–Cole plots and then further proved by Han and Van Gurp–Palman curves. Mechanical properties display an upturn following the presence of the crosslinkes. A decline in the optical properties in the films caused by the refraction of light by the crosslink structure in the film bulk and on the surface is evident.Highlights
LDPE and LLDPE were recycled according to the circular economy approach
Blown films containing virgin and recycled LDPE and LLDPE were produced
Chain scission and crosslinking as a result of recycling were studied
Rheological, thermal, mechanical, and optical properties were studied

Abstract‘Ho 13‐739’ (Reg. no. CV‐214, PI 703499) sugarcane (a Saccharum spp. complex polyploid) was selected and evaluated by scientists at the USDA‐ARS in Houma, LA, in cooperation with the Louisiana State University Agricultural Center and the American Sugar Cane League, Inc. It was released to growers in Louisiana in 2020. Results from evaluations in plant‐cane and first‐ and second‐ratoon crops at 13 field locations revealed that sucrose content and stalk weight of Ho 13‐739 were significantly greater than ‘L 01‐299’ in every crop and across the crop cycle. Sucrose yield was not significantly different than L 01‐299 for all crops evaluated and across the crop cycle. Ho 13‐739 is an early‐maturing cultivar with poor mature‐stalk cold tolerance. The cultivar is resistant to smut (Sporisorium scitamineum) and Sorghum mosaic virus and moderately suspectable to brown rust (caused by Puccinia melanocephala) and leaf scald (caused by Xanthomonas albilineans). It was also moderately susceptible to the sugarcane borer (Diatraea saccharalis F). Ho 13‐739 has important traits for producers such as high sucrose content, early maturity, and adequate disease resistance.

AbstractMultipotent mesenchymal stromal cells (MSCs)‐derived extracellular vesicles (EVs) play important roles in cellular communication and are extensively studied as promising therapeutic agents. While there is a substantial pool of studies on liquid‐phase EVs, data on EVs bound to the extracellular matrix (ECM) is lacking. There is also an emerging trend of accumulating and comparing data on characteristics of EVs obtained in different culturing conditions. Aiming to reveal proteomic signatures of EVs obtained from conditioned media and ECM of MSCs cultured in 2D and 3D conditions, we performed liquid chromatography with tandem mass spectrometry. Bioinformatic analysis revealed common patterns in proteomic composition of liquid‐phase EVs and matrix‐bound vesicles (MBVs), namely extracellular environment organization, immune, and transport pathways enrichment. However, extracellular environmental organization pathways are more enriched in liquid‐phase EVs than in MBVs, while MBVs proteins noticeably enrich enzymatic pathways. Furthermore, each type of EVs from 2D and 3D cultures has a unique differential abundance profile. We have also performed comparative functional assays, namely scratch assay to assess EVs effect on cell migration and tubulogenesis assay to evaluate EVs angiogenic potential. We found that both liquid‐phase EVs and MBVs enhance cell migration, while angiogenic potential is higher in MBVs. Results of the present study suggest that while both liquid‐phase EVs and MBVs have therapeutic potential, some unique features of each subgroup may determine optimal areas of their application.

AbstractBackgroundJob satisfaction means how happy and content people are with their job. Workers who are satisfied with their jobs tend to get more work done and give better care. When workers are not happy at work, they are also not productive as well and many of them leave their jobs. This study aimed to address the level of job satisfaction and associated factors among healthcare setting staff in Ethiopia from 2012 to 2022.MethodsPubMed, Scopus, Cochrane, Google Scholar and African Index Medicus databases have been searched based on preferred reporting items for systematic review and meta‐analysis. Pooled estimate of job satisfaction level was done using the random effects model after significant heterogeneities have been checked by subgroup analysis. Publication bias was checked using funnel plot.ResultsPooled satisfaction level of healthcare workers in Ethiopia was 50.31%. Factors associated were autonomy (pooled odds ratio (POR) = 5.79, 95% CI: 1.99–16.90), training (POR = 3.09, 95% CI: 1.69–5.67), organizational policy (POR = 4.71, 95% CI: 2.09–10.61), reward (POR = 4.58,95% CI: 1.51–13.84), payment (POR = 3.89, 95% CI: 1.77–8.54), supervision (POR = 5.34, 95% CI: 3.72–7.67) and work environment (POR = 5.44, 95% CI: 2.80–10.58).ConclusionAbout half of healthcare staff in Ethiopia's healthcare settings were satisfied with their job. This result was lower than the job satisfaction level of other parts of the world, even in African countries. Healthcare settings should strive to provide a good working environment, with training opportunities, adequate payment, supportive supervision and conducive organizational policy.

Published: January 2024

AbstractThe production of affordable advanced porous materials is necessary for applications involving the capture of CO2. This study aimed to investigate the use of inexpensive liquid precursors in the production of CO2 sorbents. Porous precursors were produced through solvothermal processing of ethylene glycol via dehydration using sulfuric acid. Various pyrolysis and activation techniques were utilized on a carbon precursor to examine how different heat treatment methods affect surface chemical properties and the behavior of static CO2 adsorption at temperatures of 273 K, 298 K, and 313 K. Out of the studied carbons, the urea‐treated pyrolyzed sample exhibited a CO2 uptake capacity of 0.93 mmol g−1 at a pressure of 0.15 bar and a temperature of 298 K. This carbon exhibited a remarkable CO2/N2 selectivity of 46, mainly due to its microporosity and a nitrogen content of 8.3 atomic percent. Moreover, the investigation of adsorption and chemical properties unveiled that nonoxidized sulfur exhibits favorable effects on CO2 adsorption, particularly at the temperature of 298 K. This study provides evidence that liquid precursors can be effectively employed to generate porous doped functional carbons or precursors using solvothermal conditions.

AbstractCellulose and its derivatives have been widely used in various applications. Cellulose can be isolated from sugarcane bagasse waste. This research aims to isolate and modify the sugarcane bagasse cellulose to improve its characteristics and usability. Cellulose was isolated using the alkalization and bleaching method, wherein the alkalization processes the biomass was immersed in a sodium hydroxide solution and bleached using hydrogen peroxide. Cellulose modification was performed using alkali treatment and etherification stages with monochloroacetic acid in an isopropanol solvent. The β‐(1,4)‐glycosidic vibration absorption on both the bleaching products at 896 cm−1 confirmed pure cellulose, while a carbonyl group at 1610 cm−1 in the modified cellulose product confirmed the pure CMC product. The CMC obtained had lower thermal stability in the interval 241.35–299.87 compared to cellulose as its source, indicating an increase in the amorphous region. According to experimental findings from the MB adsorption investigation, citric acid‐crosslinked sugarcane bagasse derivatives of carboxymethyl cellulose (CMC) were more effective adsorbents for removing MB than commercial CMC with the same formulation (2 : 1). The study‘s findings also indicated that an increase in the percentage of MB degradation was correlated with an effect of adsorbent dose and contact time.

AbstractWe have developed a Visible Light Promoted Catalyst‐Free (VLCF) approach to synthesize novel conjugates of Isoniazid and Maleimide. This method involves the formation of an electron donor‐acceptor (EDA) complex between isoniazid and maleimide the photochemical activity of this complex drives the transformation. We successfully synthesized Isoniazid‐Maleimide derivatives (3a–d) at gram scale under visible light irradiation without an additional photo catalyst and without chromatographic purification resulting in excellent yields in a recyclable green solvent. Molecular docking was employed to predict the in silico anti‐tubercular activity and binding modes at the active site of enoyl‐ACP reductase, InhA. The newly synthesized compounds (3a–d) exhibited high binding affinity compared to Isoniazid and Isoniazid‐NAD adduct, indicating their potential for more effective anti‐tubercular activity. ADME analysis revealed favourable physicochemical properties, lipophilicity, water solubility, pharmacokinetics, and drug‐likeness for compound 3a, positioning it as a promising candidate for further drug discovery and development.

AbstractDeveloping a highly efficient catalytic system for the transformation of benzhydrol to simultaneously form diphenylmethane and diphenyl ketone is an attractive strategy in modern organic synthesis. In this work, acidic mesoporous Beta (H‐MBeta) zeolite successfully catalyzed the dismutation of the benzhydrol to yield equivalent amounts of diphenylmethane and diphenyl ketone under mild conditions. Combining X‐ray diffraction, N2‐adsorption, ammonia temperature programmed desorption, pyridine‐adsorbed infrared spectra, scanning electron microscopy and transmission electron microscopy, it was found that, compared to MBeta, H‐MZSM‐5 and USY zeolite catalysts, the abundant Brønsted acidic sites on the external surface of H‐MBeta are responsible for its superior catalytic performance.

AbstractA light‐emission system coordinating the amide 2‐amino‐3‐5‐dibromo‐N‐((2‐hydroxy‐naphthalene) benzoylhydrazine (R) and Al3+ was successfully prepared. Compared with that of R, the fluorescence emission band of the R–Al3+ group considerably improved. Therefore, using the R–Al3+ complex as a donor and two dyes (Nile Red and SR101) as acceptors, two artificial light–harvesting systems (ALHSs) were prepared. The energy transfer processes of the R–Al3+–Nile Red and R–Al3+–SR101 systems were confirmed. The findings will help in improving the current situation of ALHSs and have potential application value in ion detection and energy development.

Published: January 2024

AbstractThe fabrication of flexible composites by integrating metal–organic frameworks (MOFs) with flexible substrates is a critical strategy for developing advanced materials with excellent feasibility and processability. These flexible MOF‐based composites play a particularly important role in the separation and purification processes. However, several drawbacks remain challenge to overcome such as long processing time, high‐cost, complicated processes, or harsh reaction conditions. In this paper, a convenient and efficient method is reported for fabricating MOF/fiber composites using a simple drop‐and‐drain (D&D) process. By exploiting the electrostatic interactions between the positively charged MOF particles and negatively charged fiber‐based flexible substrates, a uniform coating of MOF on flexible fibers are achieved. This is accomplished by allowing the MOF ink to drop and drain through a substrate using a custom‐made Teflon cell. Additionally, the D&D method enables the production of multiple layers of composites in a single‐step process. UiO‐66 and ZIF‐8 submicroparticles and various substrates such as cotton‐pad, cotton‐fabric, nylon‐fabric, PET‐fabric, and filter‐paper are employed to create flexible MOF/fiber composites. These composites demonstrate outstanding capacities for capturing negatively charged organic dyes, including methyl orange and indigo carmine. Furthermore, the MOF/fiber composites can be reused for dye capture after a simple washing process.

Published: January 2024

AbstractLiving cell‐mediated nanodelivery system is considered a promising candidate for targeted antitumor therapy; however, their use is restricted by the adverse interactions between carrier cells and nanocargos. Herein, a novel erythrocyte‐based nanodelivery system is developed by assembling renal‐clearable copper sulfide (CuS) nanodots on the outer membranes of erythrocytes via a lipid fusion approach, and demonstrate that it is an efficient photothermal platform against hepatocellular carcinoma. After intravenous injection of the nanodelivery system, CuS nanodots assembled on erythrocytes can be released from the system, accumulate in tumors in response to the high shear stress of bloodstream, and show excellent photothermal antitumor effect under the near infrared laser irradiation. Therefore, the erythrocyte‐mediated nanodelivery system holds many advantages including prolonged blood circulation duration and enhanced tumor accumulation. Significantly, the elimination half‐life of the nanodelivery system is 74.75 ± 8.77 h, which is much longer than that of nanodots (33.56 ± 2.36 h). Moreover, the other two kinds of nanodots can be well assembled onto erythrocytes to produce other erythrocyte‐based hitchhiking platforms. Together, the findings promote not only the development of novel erythrocyte‐based nanodelivery systems as potential platforms for tumor treatment but also their further clinical translation toward personalized healthcare.

Published: January 2024

AbstractAs one type of recent emerging lead‐free perovskites, Cs2ZrCl6 nanocrystals are widely concerned, benefiting from the eminent designability, high X‐ray cutoff efficiency, and favorable stability. Improving the luminescence performance of Cs2ZrCl6 nanocrystals has great importance to cater for practical applications. In view of the surface defects frequently formed by the liquid phase method, the particle morphology and surface quality of this material are expected to be regulated if certain intervention is made in the synthesis process. In the work, differing from normal cell lattice modulation based on the ion doping, the grain size and surface morphology of Cs2ZrCl6 nanocrystals are optimized via adding a certain amount of InCl3 to the synthetic solution. The surface defects are restored to inhibit the defect‐induced non‐radiative transition, resulting in the improvement of the luminescence properties. Moreover, a flexible Cs2ZrCl6@polydimethylsiloxane film with excellent heat, water, and bending resistance and a light‐emitting diode (LED) device are fabricated, exhibiting excellent application potential for X‐ray imaging and blue LED.

Published: January 2024

AbstractTin‐based hybrid flow batteries have demonstrated dendrite‐free morphology and superior performance in terms of cycle life and energy density. However, the quick accumulation of electrodeposits near the electrode/membrane interface blocks the ion transport pathway during the charging of the battery, resulting to a very limited areal capacity (especially at high current density) that significantly hinders its deployment in long‐duration storage applications. Herein, a conductivity‐activity dual‐gradient design is disclosed by electrically passivating the carbon felt near the membrane/electrode interface and chemically activating the carbon felt near the electrode/current collector interface. In consequence, the tin metals are preferentially plated at the region near electrode/current collector, preventing the ion transport pathway from being easily blocked. The resultant gradient electrode demonstrated an unprecedentedly high areal capacity of 268 mAh cm−2 at a current density of as high as 80 mA cm−2. Numerical modeling and experimental characterizations show that the dual‐gradient electrode differs from conventional electrodes with regard to their reaction current density distribution and electrodeposit distribution during charging. This work demonstrates a new design strategy of 3D electrodes for hybrid flow batteries to induce a desirable distribution of electrodeposits and achieve a high areal capacity at commercially relevant current densities.
