Summary: This study investigates the mechanism of dynamic crosslinking in polyborosiloxane (PBS). Through FTIR and solid-state 29Si and 11B MAS NMR analyses, the study finds that the formation of Si-O-B dynamic covalent bonds and their exchange with neighboring hydroxyl-bearing species drive the gelation and viscoelastic behavior of PBS. The study also demonstrates that the viscoelastic properties of PBS can be adjusted by the choice of boron B-O functionality.

Summary: The study characterized a rye mutant with high lodging resistance, tall posture, and high biomass production by examining its stem vascular bundles, sclerenchyma composition, and chemical features associated with lodging resistance. The findings suggested that the superior culm stability of the mutant was attributed to a combination of increased vascular bundles, more sclerenchyma, and features like elevated lignin and xylan levels. The mechanical stability and unique culm properties identified in the study may be valuable for breeders seeking to enhance lodging resistance in tall posture cereal crops.

Summary: Leather wastewater effluent is complex and difficult to degrade. Mixing it with municipal wastewater for treatment is a common practice, but the efficiency of removing dissolved organic matter from leather wastewater remains debated. This study used spectroscopy and mass spectrometry to reveal the composition and transformation of dissolved organic matter during treatment. The results showed differences in properties between leather wastewater and municipal wastewater, and the treatment process had varying removal efficiencies for different types of organic compounds. The study provides theoretical guidance for improving current treatment processes.

Summary: Infrared devices are increasingly used in various applications. This paper introduces a novel dispersive spectrometer that has high-throughput and decoupled spectral resolution. The proposed spectrometer utilizes a two-stage Hadamard transform encoding process to increase the signal-to-noise ratio. With a single-pixel detector, the system can be easily implemented in other desired wavelengths. Additionally, a method is developed to remove the need for uniform illumination and improve the ease of device design for in situ measurement.

Summary: Phototrophic biofilms play a crucial role in shaping the molecular composition and accumulation of dissolved organic matter (DOM) in periodically flooding-drying soils. They increase the abundance of labile DOM compounds and richness of molecular formulae during growth, while decreasing the relative abundance of labile components during decomposition. These findings provide insights into the potential use of phototrophic biofilms for enhancing DOM bioactivity and soil fertility in agricultural settings.

Summary: The Laguna Madre-Tamaulipas is the world's largest hypersaline lagoon with unique cyanobacteria and toxin production. A new filamentous cyanobacterium with drilling abilities has been discovered in this lagoon, displaying atypical behaviors. This discovery suggests the establishment of a new taxon and family due to significant morphological, physiological, and phylogenetic differences from its closest genus, Oxynema.

This study investigated the seasonal molecular changes in dissolved organic matter (DOM) composition in a semi-arid estuary influenced by submarine groundwater discharge. The study found that the proportion of different compounds in DOM varied across different hydroclimatic conditions, with significant differences observed during flood recession events. The influence of submarine groundwater discharge on DOM composition was highlighted as a key factor in driving these changes.

Summary: Extreme weather events, such as tropical storms and hurricanes, have a significant impact on water quality and nutrient budgets in estuaries and the coastal ocean. This study focused on the influence of negative storm surge on groundwater-surface water interactions and nutrient composition, and found that the forms and inputs of inorganic and organic nutrients fluctuated significantly in the Corpus Christi Bay after Hurricane Harvey. It was also observed that dynamic hurricane-induced negative surge events affected net nutrient budgets in estuarine and coastal seas.

Summary: Material modification with low surface energy can achieve lower surface free energy on micro-and nano-rough structures, which is crucial for developing superhydrophobic surfaces. In this study, attapulgite (APT) was modified with alkylamine, alkylammonium salt, and stearic acid, and the interaction between low surface materials and attapulgite was explained. The results showed that the hydrophobicity of APT was significantly modified by the modifiers, and the surface free energy of the composites first decreased and then increased with increasing molecular number of low surface energy monomers.

Summary: The main aim of this study was to prepare a drug-drug coamorphous system to improve the physiochemical properties, solubility and stability of Apremilast and Indomethacin. Various solid-state characterization techniques were used to characterize the prepared system. Molecular level interactions were studied using molecular modeling and ATR-FTIR and 1H NMR. Solubility and dissolution studies showed the benefits of the coamorphous system. The system was found to be stable for a period of five months. Permeation study also demonstrated improved flux for both drugs compared to their crystalline forms. The coamorphous system showed anti-psoriatic and anti-melanogenic activity based on molecular docking results. Overall, the developed CAM-based supersaturated system exhibited improved physicochemical properties and physical stability.
