controlling inflammation meanwhile facilitating tissue regeneration has been considered as a promising strategy to treat inflammatory bone defect. Herein, we describe the synthesis of a bio-sensitive poly(lactic-co-glycolic acid)/mesoporous silica nanocarriers core-shell porous microsphere(PLGA/MSNsPMS) encapsulated poly(L-lactic acid)(PLLA) spongy nanofibrous micro-scaffold as a new generation of therapeutic platform for effective reconstruction of bone defects caused by periodontal *** PLGA/MSNs-PMS were designed as stimuli-responsive carriers for on-demand co-delivery of multiple biomolecules to provide proper physiological environment, while the multi-level(from macro-,micro-to nanometers) nanofibrous and porous structures in PLLA micro-scaffold were in charge of the reconstruction of ECM, which synergistically contribute to the enhancement of new tissue formation under inflammatory condition. After local injection into periodontal tissue, this construct could sequentially release bone growth factor(BMP-2) as well as anti-inflammatory drug(celecoxib) loaded MSNs in response to the over-expressed matrix metalloproteinases(MMP) in periodontal region. During alveolar bone regeneration induced by BMP-2 and ECM like structure, the MSNs would further deliver celecoxib in target cells to achieve inflammation inhibition, resulting in effective treatment of periodontal disease.

Iodinated X-ray contrast media (ICM) are widely used in medical imaging due to their stable properties, but they cannot be effectively removed in wastewater treatment plants (especially hospital wastewater). Therefore, ICM have been widely detected in aquatic environments and may gradually accumulate and cause adverse effects to the creatures. In this paper, the degradation characteristics of two most commonly detected ICM, iohexol and diatrizoate, by ultraviolet/persulfate (UV/PS) were investigated. UV/PS can effectively degrade both ICM, with pseudo-first-order rate constants (kobs) of 0.3641 min−1 for iohexol and 0.3511 min−1 for diatrizoate, and SO4·− played a major role in UV/PS degradation of both ICM. The presence of I−, Cl−, Br−, humic acid (HA), and alkaline conditions inhibited the degradation efficiency of both ICM. Less I-DBPs were formed from iohexol at low PS and high Br− concentrations, but from diatrizoate at high PS and Br− concentrations. The degradation pathways of iohexol and diatrizoate in the UV/PS process were proposed separately according to the detected degradation intermediates. This study can provide an essential theoretical basis for the UV/PS degradation of the two ICM. © 2024 Royal Society of Chemistry. All rights reserved.

Methanol is receiving considerable attention as an alternative fuel because of its potential role as a transitional option in mitigating greenhouse gas emissions and enabling the transition towards biofuels. Recycled methanol, produced using captured CO2 or industrial by-product gases, emerges as an attractive alternative in South Korea, especially considering the excessive emissions from its energy and industrial sectors. However, assessing technological superiority amongst a range of alternatives remains challenging. This study aims to assess and compare various methanol production pathways utilizing captured CO2 and by-product gases from steel industry within context of South Korea. The selected technologies are either currently in industrial use or pivotal for future industrial applications. A unified process design and assessment framework was employed to model and simulate eight technological conversion processes. These processes underwent evaluation based on key performance indicators, accompanied by comprehensive techno-economic and environmental life cycle assessments. Additionally, comparisons were made with conventional fossil-based methanol production, considering different hydrogen and electricity production routes. This study provides valuable insights into the viability of recycled methanol pathways in terms of process performance, economic and environmental feasibility and will facilitate the practical implementation of recycled methanol, contributing towards achieving carbon neutrality objectives. © 2024, The Authors.

Ensuring the stability of electrocatalysts is paramount to the success of electrochemical energy conversion devices. Degradation is a fundamental process involving the release of positively charged metal ions into the electric double layer (EDL) and their subsequent diffusion into the bulk electrolyte. However, despite its vital importance in achieving prolonged electrocatalysis, the underlying causality of catalyst dissolution with the EDL structure remains largely unknown. Here, we show that electrochemical Pt dissolution is strongly influenced by the identity of the alkali metal cation (AM+) in the electrolyte. By monitoring Pt dissolution in real-time, we found a trend of reduced Pt leaching in the sequence Li+ > Na+ > K+ > Cs+. Our computational predictions suggest that interfacial OH- concentration plays a pivotal role in Pt dissolution, where OH- facilitates the outward diffusion of dissolved Pt ions into the bulk electrolyte by neutralizing the Ptz+ species, thereby screening the migration force for their redeposition. Combined with this theoretical result, we verify a strong correlation between the amount of dissolved Pt and the hydrolysis pKa or acidity of AM+, indicating that the AM+ identity determines the local OH- concentration and thereby modifies the amount of Pt dissolution. Our results underscore the need to tune the EDL structure to achieve durable electrocatalysis, a promising area for future research. © 2025 American chemical Society.

Quantum entanglement plays a key role in both understanding the fundamental aspects of quantum physics and realizing various quantum devices for practical applications. Here we propose how to achieve a coherent switch of optomechanical entanglement in an optical whispering-gallery-mode resonator, by tuning the phase difference of the driving lasers. We find that the optomechanical entanglement and the associated two-mode quantum squeezing can be well tuned in a highly asymmetric way,providing an efficient way to protect and enhance quantum entanglement against optical backscattering, in comparison with conventional symmetric devices. Our findings shed a new light on improving the performance of various quantum devices in the practical noisy environment, which is crucial in such a wide range of applications as noise-tolerant quantum processing and the backscattering-immune quantum metrology.

Development of a hazard index for reactivity management (HIRM) in chemical process

The management of reactivity hazards has long been a problem in chemical process and the indexing approach is believed to be an effective solution. However, while most of the reactivity indexes do not consider the runaway scenario and are often quite rough, the assessment criteria used to judge thermal runaway does not take the type of scenario or the severity of the consequences into account. At present, there are no index system that can represent the reactivity hazards in chemical process comprehensively. Therefore, this paper has developed a hazard index for reactivity management (HIRM) in chemical processes. The reactivity hazards could be identified, evaluated and managed through nine steps defined by this method. The HIRM method is able to assess various runaway scenarios and quantify the reactivity hazards based on the consequence and probability. The consequence is rated by the damage radius which represents the damage level caused by fire, explosion, and toxic release due to reaction runaway. The probability indicates the initial event frequency, the initiation time and the controllability of the entire runaway process. The reactivity risks could then be classified by the HIRM index uniformly and comprehensively, with methods to manage the risks proposed. Six sets of equipment in the dicumyl peroxide (DCP) production unit was used as an example to demonstrate the construction of the HIRM index system. The results showed good agreement with the actual risk distribution, meaning that the HIRM method is an effective tool for the management of reactivity hazards in chemical process. © 2020
