Summary: In this study, sulfide and chloride ions were successfully doped into ZnO through hydrothermal method. The doped ZnO nanostructures showed no significant change in morphology, retaining the wurtzite crystal structure with a red shift in XRD results. The successful doping of sulfide and chloride ions was confirmed by elemental analysis. Importantly, the optical band gap of ZnO was reduced upon doping, leading to enhanced photocatalytic properties. The doped ZnO photocatalyst achieved a high photo-degradation efficiency of methylene blue.

Summary: Zinc oxide nanoparticles were successfully synthesized using glycine nitrate solution combustion synthesis. The synthesized nanoparticles exhibited a pure hexagonal wurtzite-like structure of ZnO. They showed effective visible light catalytic activity in the degradation of methylene blue dye, degrading 98% of the dye in 120 minutes with 0.1 g/L of catalyst loading. Photoluminescence studies suggested that the enhanced photocatalytic activity may be attributed to the presence of singly ionized oxygen vacancy or intrinsic defects.

Summary: Immobilization of metal-organic frameworks (MOFs) on electrospun products for wastewater treatment has gained attention. The effect of the overall geometry and surface-area-to-volume ratio of MOF-decorated electrospun architectures on their performances was investigated. Helicoidal PCL/PVP strips were prepared via immersion electrospinning and Zeolitic Imidazolate Framework-8 (ZIF-8) was immobilized on the strips. The high surface-area-to-volume ratio of the ZIF-8-decorated helicoidal strips resulted in improved performance for MB adsorption and photocatalytic degradation.

Summary: Wastewater from the textile industry, which contains various organic dyes, poses a chronic and hazardous problem for human health. A study conducted on the treatment of this wastewater using low-cost and efficient photocatalyst technology found that ZnO microstructures grown in the presence of psyllium husk showed enhanced photocatalytic activity towards the degradation of methylene blue. The psyllium husk modified the surface of the ZnO microstructures, created defects in the crystal structures, and altered the morphology of the nanostructured material. The addition of carbon from the thermal combustion of psyllium husk further improved the photocatalytic performance. The research also explored the optimal dosage of photocatalyst for efficient photodegradation of methylene blue.

Summary: Synthesis of ZIF-8 using acetic acid as solvent resulted in uniform nanoparticles with enhanced adsorption properties for methylene blue removal. Compared to ZIF-8 produced using N,N-dimethylformamide solvent, ZIF-8 (AA) showed smaller particle size, enhanced mesoporosity, higher surface area, and greater adsorption capacity. The adsorption of methylene blue followed pseudo-second order kinetic and Langmuir model on ZIF-8 (AA), indicating its efficiency for dye removal.

Summary: By using silver nanowires (AgNWs) as photo-enhanced material, the ZIF-8@AgNWs composite with fully encapsulated shell-core structure of ZIF-8-AgNWs is successfully synthesized via in situ growth method. The addition of AgNWs significantly increases the light absorption of the ZIF-8@AgNWs composite, and the bandgap of ZIF-8@AgNWs is 2.9 eV, with a significant decrease compared to pure ZIF-8 (4.96 eV). The ZIF-8@AgNWs-2 exhibits the best photocatalytic activity for methylene blue (MB) degradation, with a degradation efficiency of 94% and an apparent rate constant of 0.04371 min(-1).

Summary: Converting CO2 into chemical energy through efficient photocatalysts is a promising approach to meeting energy demands and reducing greenhouse gas emissions. This study developed hierarchical ZnO@ZnFe2O4 hollow polyhedrons decorated with CdS quantum dots to enhance the photocatalytic CO2 reduction performance. The synthesis involved the thermal decomposition of 2-Methylimidazole zinc salt (ZIF-8) precursor to produce ZnO hollow polyhedrons, followed by in situ generation of Zn-Fe layer double hydroxide nanosheets and thermal treatment to form ZnFe2O4 nanosheets. The hierarchical structure of the ZnO@ZnFe2O4 hollow polyhedrons provides favorable active sites for CO2 adsorption and reduction.

Summary: A series of CdS-modified zeolitic imidazolate framework-8 (ZIF-8)-derived porous carbons (CZCs) were fabricated using a facile method, with CZC600-30 showing optimum photocatalytic activity for degrading organic pollutants such as methylene blue and tetracycline within 60 minutes under visible-light irradiation.

Summary: In this study, a novel metallic heterostructure composed of defect-rich nickel and amorphous/crystalline molybdenum nitride anchored on a carbon matrix (MoN/Ni@C) was fabricated and demonstrated as a superior electrocatalyst for the hydrogen evolution reaction (HER). The MoN/Ni@C electrocatalyst exhibited low HER overpotential and small Tafel slope, along with excellent stability in alkaline solution. Density functional theory calculations revealed that the interfacial electron transfer contributed to the distortion of Ni surface and the optimal thermoneutral hydrogen adsorption free energies on Mo and Ni active sites. The amorphous/crystalline structure in the MoN phase provided more active sites and promoted structural stability. This work provides new insights into designing non-noble-metal-based electrocatalysts with superior HER activities.

Summary: This paper introduces a novel approach for designing a dual-polarized liquid crystal (LC) unit cell, which reduces the thickness of the LC layer without affecting its loss and phase shift. The unit cell consists of a tunable superstrate made of LC between a cross patch and a square patch. The LC layer can vary the resonant frequency and phase of the unit cell to achieve 2-D beam steering. Simulation and manual fabrication of a dual-polarized reflectarray (RA) demonstrate its effectiveness in the 28 GHz band.

Summary: Liquid chromatography coupled to mass spectrometry (LC-MS) is utilized for host cell proteins (HCP) identification in antibody drug development, but its application in prokaryotic-derived growth hormone (GH) samples is rare. In this study, a universal workflow combining optimized sample preparation and one-dimensional ultra-high performance LC-MS-based shotgun proteomics was developed to profile HCP in GH samples, providing guidance for purification process development and biosimilar development. A standard-spiking strategy was also developed to enhance HCP identification, enabling trace-level HCP analysis. These protocols open avenues for HCP profiling in biotherapeutics derived from prokaryotic host cells.

Summary: This study introduces a powder metallurgy route to enhance the mechanical properties of equiatomic CoCrNi medium-entropy alloys using multiple strengthening mechanisms. The yield strength of the alloy produced by mechanical alloying is significantly higher than that of alloys prepared from commercial powders or casting. The coordination of ultra-fine grains, twins, and high-density stacking faults contributes to the enhanced strength. Molecular dynamic simulations further demonstrate the influence of twins and stacking faults on the grain refinement effect. These findings highlight the effectiveness of mechanical alloying in producing MEAs with superior strength.

Summary: An efficient flame retardant (ADM) with phosphophenanthrene and thiazole groups was synthesized to alleviate the fire hazard of epoxy resin (EP). EP/4% ADM composites containing only 0.25% phosphorus reached UL-94 V-0 rating and had a high limiting oxygen index of 35.8%. The improved flame retardancy was attributed to the decomposition of DOPO, which captured reactive radicals, and the dilution effect of the thiazole group.

Summary: CDKN2A/B deletion or silencing is common in human cancer, highlighting the importance of bypassing its tumor suppression. In childhood cancers like RMS and neuroblastoma, CDKN2A/B transcripts are expressed independently, but one, ARF, is always silenced. TGF beta can induce CDKN2A/B transcripts, but only when cells are pretreated with methyltransferase inhibitors or EZH2 inhibitors, suggesting a crosstalk between methyltransferase inhibition and TGF beta-dependent activation.
