AuNPs/MXene nanocomposites were synthesized and used for selective and enhanced LDI-MS detection of cysteine in urine. Cysteine binds to the AuNPs in the composite, providing detection selectivity, whereas signal enhancement is obtained via the formation of a "coffee ring" as the nanocomposite and cysteine dry on the target substrate. The accumulation of AuNPs/MXene with cysteine at the outer ring on different substrates enhances the ion abundance of cysteine compared with a conventional MALDI matrix. Selective separation of cysteine with the nanocomposites in the drying droplet results in fewer detection interferences and leads to highly reproducible and sensitive detection of cysteine. The coffee ring formation of cysteine and the AuNPs/MXene nanocomposites allows for direct detection of cysteine with a linear response over a clinically relevant concentration range. We also demonstrated selective detection of urinary cysteine on PVC, suggesting that this detection platform could be applied for facile detection of urinary cysteine in wearable diapers. © 2024, The Authors.

The hydrolysis of DNA serves as the foundational principle for gene engineering that enable precise gene cleavage at the molecular level. This process typically occurs in biological nucleases, which exhibit nucleobase-selective and catalytic hydrolysis capabilities rarely replicated in abiotic nanomaterials. Here, we demonstrate that molybdenum-terminated (Mo-terminated) edges of molybdenum disulfide (MoS2) possess the unique ability to abstract a proton (H+) from water molecules, thereby facilitating catalytic hydrolysis reactions that cleave the phosphodiester bonds in DNA through the action of hydroxide ions. The enhanced proton absorption at Mo-terminated edges of MoS2 significantly reduces the activation energy required for the DNA hydrolysis reaction. Furthermore, the favorable interaction between the Mo-terminated edges and thymine nucleobases promotes both charge transfer and P-O bond cleavage, enabling targeted DNA hydrolysis at 'TTTTTTT' sequences under dark conditions. This discovery underscores the potential of MoS2 as a stable, efficient nanosystem for precise genetic editing, heralding advanced applications in the field of gene engineering. © 2024, The Authors.

We developed a molybdenum (Mo)-doped cobalt (Co)-heterostructure embedded on a phosphorous (P) and nitrogen (N) dual-doped porous carbon which exhibits an intrinsic electronic transport channel of Co to Mo and P. The P,Mo,O−Co/PNC/NF (NF=Nickel foam) electrode offers 335 mV overpotential at 10 mA cm−2 in OER as compared with PMA-ZIF67-NC/NF and ZIF67-NC/NF electrode with an overpotential of 357 and 373 mV respectively. Linear sweep voltammetry (LSV) of overall water splitting (OWS) supports that the current density gradually increased at a cell potential of 1.6 V with a maximum of 40 mA with a corresponding cell potential of 1.79 V at a current density of 10 mA cm−2. Density functional theory (DFT) calculations for water adsorption on optimized [111] surface of Co, CoMo, and CoMoP2 with adsorbed H2O and corresponding lattice determine the electron density difference of [111] surface with adsorbed H2O for Eads (eV) 4.23 corresponds to adsorption energy for CoMoP2. XANE-EXAFS spectroscopy of P,Mo,O−Co/PNC at Co K edge and Mo K edge suggests the presence of higher valence of both Cox+ and Mox+ without metallic Co and Mo and Co−P and Mo−P bonds as major structural units due to phosphidation as determined by R-space FT-EXAFS spectra. © 2024 Wiley-VCH GmbH.

The study investigated the potential of wastewater-derived microalgae as a cost-effective feedstock for bioethanol production. The influence of CO2 loading, use of swine wastewater as a nutrient source, effect of micronutrients in the cultivation media, and scale-up of Chlorella vulgaris FSP-E was conducted. Results showed that 2% CO2, 25% swine wastewater, 500 mg/L sodium nitrate, 40 mg/L K2HPO4, 75 mg/L MgSO4, and 6 mg/L citric acid were optimal for maximal biomass production, nitrate removal, and carbohydrate accumulation in BG-11 medium. The maximum biomass and carbohydrate content obtained in this study were 35-fold and 60%, respectively. Scaling up to 5 L volume was challenging due to illumination, aeration, and mixing issues. The obtained carbohydrate-rich biomass was subjected to mild sulfuric acid hydrolysis and subsequently used for bioethanol fermentation. The hydrolysate was composed solely of glucose and galactose and was converted into bioethanol within 8 h by Saccharomyces cerevisiae with an ethanol yield of 0.22 ± 0.01 g ethanol per g biomass. Further exploration of effective lighting and mixing strategies are recommended to realize economically viable microalgal biofuels. © 2024 Elsevier Ltd

In this study, we investigated the drying properties of Sentang (Azadirachta excelsa) dried at different temperatures. Sentang tree planted in Kelantan, Malaysia, was used in this study. Drying specimens with dimensions of 30 ×150 × 500 mm were dried under air-drying conditions, a constant temperature of 60, 80, 100, and 120 °C until the moisture content (MC) of the specimens reaches an equilibrium moisture content (EMC) at each drying condition. The drying properties of the specimens were then examined. The results confirmed that drying temperature had a significant effect on drying time. As expected, drying Sentang under air-drying conditions demanding considerable time than the other drying conditions. © Published under licence by IOP Publishing Ltd.

Atomically thin indium selenide (InSe) exhibits a sombrero-like valence band, leading to distinctive excitonic behaviors. It is known that the indirect band gap of atomically thin InSe leads to a weak emission from the lowest-energy excitonic state (A peak). However, the A peak emission of monolayer (ML) InSe was observed to be either absent or very weak, rendering the nature of its excitonic states largely unknown. Intriguingly, we demonstrate that ML InSe exhibits pronounced PL emission because of the efficient brightening of the momentum-indirect dark excitons. The mechanism is attributed to acoustic phonon-assisted radiative recombination facilitated by strong exciton-acoustic phonon coupling and extended wavefunction in momentum space. Systematic analysis of layer-, power-, and temperature-dependent PL demonstrates that a carrier localization model can account for the asymmetric line shape of the lowest-energy excitonic emission for atomically thin InSe. Our work reveals that atomically thin InSe is a promising platform for manipulating the tightly bound dark excitons in two-dimensional semiconductor-based optoelectronic devices. © The Author(s) 2024.

Ascertaining the function of in-plane intrinsic defects and edge atoms is necessary for developing efficient low-dimensional photocatalysts. We report the wireless photocatalytic CO2 reduction to CH4 over reconstructed edge atoms of monolayer 2H-WSe2 artificial leaves. Our first-principles calculations demonstrate that reconstructed and imperfect edge configurations enable CO2 binding to form linear and bent molecules. Experimental results show that the solar-to-fuel quantum efficiency is a reciprocal function of the flake size. It also indicates that the consumed electron rate per edge atom is two orders of magnitude larger than the in-plane intrinsic defects. Further, nanoscale redox mapping at the monolayer WSe2–liquid interface confirms that the edge is the most preferred region for charge transfer. Our results pave the way for designing a new class of monolayer transition metal dichalcogenides with reconstructed edges as a non-precious co-catalyst for wired or wireless hydrogen evolution or CO2 reduction reactions. Systematically study of in-plane intrinsic defects and edge atoms is important to guide the design of low-dimensional photocatalysts. Here the authors investigate photocatalytic CO2 reduction to CH4 over reconstructed edge atoms of monolayer semiconducting WSe2.

The trirutile structure holds significant potential for use in affordable photovoltaic and optoelectronic devices. This manuscript examines MgSb 2 O 6 material structural, thermodynamic, electronic, optical, and mechanical properties utilizing density functional theory (DFT) simulations. Additionally, we investigate the effects of hydrostatic pressure ranging from 0 to 70 GPa on these physical properties. Our study presents the first theoretical framework for analyzing the behaviour of MgSb 2 O 6 under pressure, offering valuable insights into its properties. The compound retains a tetragonal crystal structure across this pressure range, and the derived lattice constants align with those reported in other experimental studies. Moreover, the thermal properties of the MgSb 2 O 6 compound have been determined, including enthalpy, free energy, heat capacity, entropy, and Debye temperature, which can support future experimental and theoretical investigations of this material. Due to their high Debye temperatures, the components under study exhibit relatively high melting points. The electronic density of states (DOS) and electronic band structures were evaluated with the GGA-PBE exchange correlation function, the results reveal that the direct (Γ-Γ) energy bandgap value increases and shifts in the ultraviolet spectrum by applying pressures from 0 to 70 GPa. The optical properties of the MgSb 2 O 6 compound are described in detail, including dielectric function, absorption, reflection, conductivity, and refractive index, which highlight the potential of this material for optoelectronic and engineering applications. The increase in the elastic modulus value indicates that MgSb 2 O 6 becomes stiffer under stress. The Poisson’s and Pugh’s ratios also show that the compound transforms from brittle to ductile when pressure is applied. Pressure significantly affects this material’s anisotropy factor, causing deviations from a spherical shape. This discovery brings up interestin

Increased levels of surfactant protein D (SP-D) and lipid-laden foamy macrophages (FMs) are frequently found under oxidative stress conditions and/or in patients with chronic obstructive pulmonary disease (COPD) who are also chronically exposed to cigarette smoke (CS). However, the roles and molecular mechanisms of SP-D and FMs in COPD have not yet been determined. In this study, increased levels of SP-D were found in the bronchoalveolar lavage fluid (BALF) and sera of ozone- and CS-exposed mice. Furthermore, SP-D-knockout mice showed increased lipid-laden FMs and airway inflammation caused by ozone and CS exposure, similar to that exhibited by our study cohort of chronic smokers and COPD patients. We also showed that an exogenous recombinant fragment of human SP-D (rfhSP-D) prevented the formation of oxidized low-density lipoprotein (oxLDL)-induced FMs in vitro and reversed the airway inflammation and emphysematous changes caused by oxidative stress and CS exposure in vivo. SP-D upregulated bone marrow-derived macrophage (BMDM) expression of genes involved in countering the oxidative stress and lipid metabolism perturbations induced by CS and oxLDL. Our study demonstrates the crucial roles of SP-D in the lipid homeostasis of dysfunctional alveolar macrophages caused by ozone and CS exposure in experimental mouse emphysema, which may provide a novel opportunity for the clinical application of SP-D in patients with COPD.

Magnesium rechargeable batteries are attracting attention as next-generation rechargeable batteries because of their resource abundance, cost, safety, and high electrical capacity per volume compared to conventional lithium-ion rechargeable batteries. Our joint research team focused not only on the electrochemically active magnesium composition of ribbon for the negative electrode materials of magnesium rechargeable batteries but also on the production process, focused on the single roll type liquid quenching and rapid solidification method, which can be produced at a lower cost. In this study, the optimal processing conditions were examined by comparing CAE analysis with ribbon actually manufactured, with the aim of further improving manufacturing conditions using the same method, such as length discontinuities, thickness, and surface properties of ribbon. We specifically various process parameters such as injection pressure and roll peripheral speed for evaluation. As a result, several linear cracks were observed on the surface of the ribbon as the peripheral speed increased and as the Gap became wider, and the surface properties tended to deteriorate. Also, It was found that the dominant factor in the length of the ribbon was the peripheral speed. As the peripheral speed increased, the length of the ribbon tended to increase. © 2023 Japan Institute of Light Metals. All rights reserved.
