Summary: Proper dispersion of additives within a polymer matrix is crucial for achieving desired effects. However, poor interactions between the polymer and additive often make dispersion difficult. This study explores the use of a hydrogen bonding capable polymer to reduce the domain size of melamine cyanurate (MC) in polymer matrices, leading to improved dispersion. By disrupting the intramolecular hydrogen bonding of MC with a water-soluble polymer, the particle size of MC was reduced by at least 50% and the homogeneity of the domain size was improved.

Summary: An intrinsic flame retardant copolyester based on PET and thermo-tropic liquid crystalline polymer (PET/TLCPx) was designed and prepared via a simple and efficient one-step melt copolymerization. PET/TLCPx exhibits excellent thermal stability, fire resistance, and non-dripping properties due to the formation of a denser char layer and the increase of complex viscosity and molecular weight during combustion. These high-performance copolyesters are highly valuable for high-end applications with strict requirements for fire safety and thermal stability.

Summary: This study investigates the properties of crosslinked LLDPE/LDPE blend by incorporating ATH filler and MMT nanoclay. The results show that ATH loading improves the mechanical, thermal, and flame retardancy properties of the blend. However, the addition of MMT nanoclay does not significantly increase the tensile strength at higher ATH loading. Additionally, the inclusion of higher ATH filler content and MMT nanoclay increases the complex viscosity and storage modulus of the original LLDPE/LDPE blend.

Summary: Photocrosslinking of polymers for industrial applications has advantages in terms of mild conditions and economical equipment. However, issues such as the use of mercury lamps as light sources and the presence of powdered materials as additives pose concerns. This study explores the UV-curing of an innovative EVA-POE blend containing hydrotalcite and aluminum hydroxide as flame-retardant fillers using a 370-nm UV LED. The results show a higher cross-linked content compared to pure EVA and LDPE, even with the presence of light scattering mineral fillers at high concentration.

Summary: This study explored the fire-safety capabilities of cyclic phosphoramides with different substitutions on PET fabric. It was found that these compounds exhibited good flame retardancy and non-dripping performance. The flame-retardant coatings enhanced the char-forming capacity of PET fabric and effectively reduced the peak heat release rate and total heat release. Furthermore, these coatings had no detrimental effects on the mechanical characteristics of PET fabric and even improved the weft's tensile breaking forces.

Summary: An inherent functional PA6 copolymer (PADA) with low melting point and good anti-dripping performance was designed via a simple bulk copolymerization method. By introducing azobenzene as the functional segment and ethylene glycol as a chain-linker, the melting point of PADAs was significantly reduced compared to PA6 due to the disrupted regularity of the molecular chain. The PADAs exhibited high LOI value and completely suppressed melt-dripping behavior, which was attributed to the synergistic effect of azobenzene and EG resulting in a formed crosslinked network during combustion.

Summary: Water redistribution has a profound impact on the function of dryland ecosystems. Biological soil crusts (BSCs or biocrusts), which cover a large portion of arid land soil surface, have conflicting effects on water redistribution at a regional scale. This study clarified the effects of different biocrusts on soil hydraulic properties in the Tengger Desert. The results showed that biocrusts significantly altered soil hydraulic properties, including water holding capacity, soil hydrophobicity, water sorptivity, and unsaturated hydraulic conductivity. Understanding the role of biocrusts in hydraulic properties can help improve our understanding of soil water distribution, movement, and retention in the area.

Summary: The purpose of this study was to evaluate the biological effects of cancer stem cells (CSCs) irradiated by charged particle, including proliferation, invasion, migration, and changes in the molecular level. The results showed that CSCs have obvious radio-resistance compared with non-CSCs, and charged particle irradiation or in combination with drugs could overcome this resistance, specifically manifested in inhibiting CSCs' proliferation, invasion, migration, and causing more and harder to repair DNA double-stranded breaks (DSB) of CSCs.

Summary: A new perfect triangular lattice antiferromagnet K2Ni(SeO3)(2) has been synthesized, in which both in-plane and inter-plane geometric frustration is present. The compound shows antiferromagnetic order at T(N) ≈ 7 K. High-field magnetization and electron spin resonance indicate the presence of easy-plane anisotropy. Density functional theory calculations confirm the excellent two-dimensionality of the compound. Thus, K2Ni(SeO3)(2) is a perfect triangular-lattice antiferromagnet with strong frustration and easy-plane anisotropy.

The results showed that non-benzodiazepines, antidepressants, and orexin receptor antagonists may have positive effects on improving total sleep time, sleep onset latency, and wake time after sleep onset. The choice of insomnia drugs should consider the individual's insomnia phenotype, as well as the safety and tolerability of each drug.

Summary: Through a systematic review and meta-analysis of 37 cohort studies, it was found that an increased consumption of sugar-sweetened beverages (SSBs) per 250 mL/day was associated with a higher risk of breast, colorectal, biliary tract, and prostate cancer. Increased consumption of artificially sweetened beverages (ASBs) per 250 mL/day was associated with a higher risk of leukemia. Increased consumption of 100% fruit juice per 250 mL/day was associated with a higher risk of overall cancer, melanoma, squamous cell carcinoma, and thyroid cancer. There were linear dose-response associations between SSBs consumption and breast and kidney cancer, and between ASBs and fruit juices consumption and pancreatic cancer.

Summary: This study evaluated the effects of head-of-bed elevation on patients with acquired brain injury (ABI). The results showed that elevating the head of the bed by 30 degrees can significantly reduce intracranial pressure (ICP), but did not have statistical differences on cerebral perfusion pressure (CPP) and disability at 90 days. Therefore, head-of-bed elevation of 30 degrees may be an effective noninvasive nursing practice for the prognosis and rehabilitation of ABI patients.

Summary: This investigation examines the relationship between the structure and properties of surface-grafted cellulose nanofiber (CNF)-based one-component composites. Key parameters, such as graft density, graft chain length, and interface structure, were systematically adjusted. Increasing the graft density and hydrophobic modification of the CNF surface improved thermal stability. Shorter graft chain length increased the T(g) of the graft chain while hydrophobic modification and longer graft chain length decreased stiffness. Decreasing graft density remarkably enhanced toughness and strength. The interfacial interaction between CNF and grafted polymer played a crucial role in determining the composites' properties, along with graft density.

Summary: The CYP76 subfamily, which belongs to the CYP superfamily, is crucial for phytohormone biosynthesis and response to environmental stresses in plants. Genome-wide analysis of the CYP76 subfamily in seven AA genome species revealed three groups, with Group 1 having the largest number of members. Analysis of cis-acting elements showed a high number of elements related to jasmonic acid and light response. Gene duplication analysis indicated expansion mainly through SD/WGD and tandem forms, with strong purifying selection during evolution. Expression pattern analysis showed that OsCYP76s exhibit restricted expression patterns in leaves and roots. qRT-PCR analysis of CYP76s under abiotic stresses revealed specific response patterns and functional divergence between japonica and indica rice. These findings provide valuable insights into the functional diversity and evolution of the CYP76 subfamily and have implications for improving stress tolerance and agronomic traits in rice.
