One possible way to address the shortcomings of current acid detection is to add fluorescence detection capabilities, however, there is little data regarding wavelength-based luminescence sensing, which makes possible for the naked eye to perceive various colors through wavelength variations. In this paper, we achieved turn-on response and wavelength-based luminescence sensing on acids detection by using donor-accepter complex Fe-L, which display significant fluorescence discoloration in the presence of a wide range of inorganic and organic acids, including benzoic acids, providing the fluorescence response for a more intuitive and convenient acid detection. The simultaneous achievement of fluorescence enhancement and color change as the acid concentration changes enables visual detection of the acid concentration, which provides a foundation for future research into convenient detection methods for various types of acids.

Atmospheric water harvesting has emerged as an efficient strategy for addressing the global challenge of freshwater scarcity. However, the in being energy-consuming water-collecting process has obstructed its practicality. In this work, a soft drain bed, which was composed of hydrophilic cloth and hygroscopic gel, has been demonstrated to capture atmospheric water effectively, followed by converting it into liquid water spontaneously and sustainably, under all-weather humidity conditions.

CRISPR-Cas tools for mammalian genome editing typically rely on single Cas9 or Cas12a proteins. While type I CRISPR systems in Class I may offer greater specificity and versatility, they are not well-developed for genome editing. Here, we present an alternative type I-C CRISPR system from Desulfovibrio vulgaris (Dvu) for efficient and precise genome editing in mammalian cells and animals.

The leather manufacturing industry is increasingly embracing chrome-free tanning methods to promote environmental sustainability. However, the transition to chrome-free tanning systems presents a notable obstacle: the incompatibility of traditional anionic wet finishing materials with chrome-free tanned leather due to differences in surface electrical behavior. Herein, an amphoteric polymer, referred to P(AA-co-DMAEMA-co-DA), was synthesized through a simple one-step free radical copolymerization using acrylic acid (AA), dimethylaminoethyl methacrylate (DMAEMA), and dodecyl acrylate (DA).

Background: Compelling evidence suggests that calcium/phosphorus homeostasis-related parameters may be linked to diabetes mellitus and cardiovascular events. However, few studies have investigated the association of fibroblast growth factor 23 (FGF23), α-klotho and FGF23/α-klotho ratio with atherosclerosis in patients with type 2 diabetes mellitus (T2DM).

Objective: This study was designed to evaluate whether FGF23, α-klotho and FGF23/α-klotho ratio are associated with T2DM and further to explore the relationships between these three factors and atherosclerosis in Chinese patients with T2DM.

The oxidation characteristics and spontaneous combustion (SC) tendency of raw long-flame coal (RC), water-soaked 200-day coal (S), pre-oxidized water-soaked coal at 200 °C (OS), and pre-oxidized soaked coal at 300 °C (OS) in an oxygen-poor environment were investigated using a programmed warming system. The results show that pre-oxidation water-soaked treatment (PWT) promotes the coal-oxygen complex reaction and increases the rate of coal oxygen consumption (OCR) and the rate of carbon and oxygen compound production. The rate of CO and CO production of the water-soaked (WS) coal increased by 0.

  • * Utilizing thermal analysis and experimental techniques like EPR and FTIR, it examines how increased temperatures lead to changes in coal's active groups, with heat release and functional group accumulation becoming more pronounced.
  • * Findings reveal that high temperatures (>160 °C) accelerate the breakdown of active free radicals, leading to a decrease in characteristic temperatures and heat release, while increasing the risk of spontaneous combustion in deeply mined areas.

Spinel bimetallic transition metal oxide anode such as ZnMnO, has drawn increasing interest due to attractive bimetal interaction and high theoretical capacity. While it suffers from huge volume expansion and poor ionic/electronic conductivity. Nanosizing and carbon modification can alleviate these issues, while the optimal particle size within host is unclear yet.

Long-term sequelae clustering phenotypes are important for precise health care management in COVID-19 survivors. We reported findings for 1000 survivors 20 months after diagnosis of COVID-19 in a community-based cohort in China. Sequelae symptoms were collected from a validated questionnaire covering 27 symptoms involved in five organ systems including self-reported physical condition, dyspnea, cognitive function and mental health.

Defects engineering has played an ever-increasing important role in electrochemistry, especially secondary lithium batteries. TiO is regarded as a promising anode due to its attractive cycling stability, low volume strain and great abundance, while challenges of intrinsic poor electrical and ionic conductivity remain to be addressed. Herein, we report a three-in-one oxygen vacancy (V)-involved pomegranate design for TiO/C composite anode, which provides highly improved electrical conduction, shortened Li pathway and promoted Li redox.

This paper describes a new method combining octenyl succinic anhydride (OSA) esterification and high hydrostatic pressure for starch modification, which interacts with conjugated linoleic acid (CLA) to form an octenyl succinic anhydride-lotus seed starch-conjugated linoleic acid (OSA-LS-CLA) complex. This method proves the formation of complex observed by fourier transform infrared spectroscopy and complex index. The stable structure of the complex was derived from increasing molecular weight by introducing macromolecular conjugated linoleic acid and the higher crystallinity than original starch observed by X-ray diffraction.

  • Respiratory infections like SARS, H1N1, and COVID-19 have posed significant threats to global health, leading to unclear recommendations regarding facemask usage due to lack of solid evidence on their effectiveness.
  • A meta-analysis of 21,341 records included 8 randomized controlled trials (RCTs) and 78 studies focusing on facemask efficacy and public perception, revealing that facemasks can notably reduce infection risk, especially when used for longer than two weeks.
  • The analysis showed that while 71% of participants believe facemasks are effective and 68% intend to wear them, actual usage was lower at 54%, with regional differences in attitudes influenced by cultural factors and public health policies.
