On August 12, 2021, Kaye, Esther G.; Kailass, Karishma; Sadovski, Oleg; Beharry, Andrew A. published an article.Related Products of 93-04-9 The title of the article was A Green-Absorbing, Red-Fluorescent Phenalenone-Based Photosensitizer as a Theranostic Agent for Photodynamic Therapy. And the article contained the following:

Phenalenone is a synthetically accessible, highly efficient photosensitizer with a near-unity singlet oxygen quantum yield. Unfortunately, its UV absorption and lack of fluorescence has made it unsuitable for fluorescence-guided photodynamic therapy against cancer. In this work, we synthesized a series of phenalenone derivatives containing electron-donating groups to red-shift the absorption spectrum and bromine(s) to permit good singlet oxygen production via the heavy-atom effect. Of the derivatives synthesized, the phenalenone containing an amine at the 6-position with bromines at the 2- and 5-positions (OE19) exhibited the longest absorption wavelength (i.e., green) and produced both singlet oxygen and red fluorescence efficiently. OE19 induced photocytotoxicity with nanomolar potency in 2D cultured PANC-1 cancer cells as well as light-induced destruction of PANC-1 spheroids with minimal dark toxicity. Overall, OE19 opens up the possibility of employing phenalenone-based photosensitizers as theranostic agents for photodynamic cancer therapy. The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Related Products of 93-04-9

On June 1, 2022, Tian, Yexin; Zheng, Pu; Mu, Yingchun; Su, Wei; Chen, Tianyan published an article.Name: 1,4-Dimethoxybenzene The title of the article was Correlation analysis of normal and moldy beef jerky microbiota with Volatile compounds. And the article contained the following:

In this study, the microbial composition and volatile flavor components of normal beef jerky (NBJ) and moldy beef jerky (MBJ) from three different regions were examined using high-throughput sequencing (HTS) and headspace solid-phase microextraction combined with gas chromatog.-mass spectrometry (HS-SPME-GC-MS) to explore the effects of microbial and environmental factors on MBJ, and the correlation between core microorganisms and volatile compounds were revealed using Spearman rank correlation anal. (|r | >1, P < 0.05). At the genera level, Aspergillus, Xeromyces and Wallemia were the dominant fungi. While Nicotiana_Otophora, Staphylococcus, Bacillus, Brochothrix and Acinetobacter were the dominant bacterial genera. 82 Volatile compounds were identified in beef jerky from different regions. The correlation heat map between microorganisms and volatile compounds showed that eight core microbial genera had significant effects on the flavor quality of beef jerky after mold (VIP>1, P < 0.05), including five fungal and 3 bacteria, namely Arthrobacter, Xerochrysium, Dryomyces, Aspergillus, Colletotrichum, Bacillus, Staphylococcus and Salvia_pomifera. Bacillus, Staphylococcus, Salvia_pomifera and Colletotrichum had significant effects (P < 0.05) on 18 compounds, which may be classified as key microorganisms that affect beef jerky spoilage. Our study provides a theor. reference for solving the problem of MBJ. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Name: 1,4-Dimethoxybenzene

Stallard, Charlie P.; Solar, Pavel; Biederman, Hynek; Dowling, Denis P. published an article in 2016, the title of the article was Deposition of Non-Fouling PEO-Like Coatings Using a Low Temperature Atmospheric Pressure Plasma Jet.Electric Literature of 929-37-3 And the article contains the following content:

Plasma polymerized PEO-like films were deposited from tetraethylene glycol di-Me ether (TEGDME) and diethylene glycol vinyl ether (DEGVE) using an atm. plasma jet. Films formed from TEGDME with C-O-C retention >50% showed anti-fouling properties, while DEGVE films with C-O-C >60% did not. TEGDME films deposited at higher monomer flow rates had a lower d. and more amorphous phases in the polymer network. Consequently, these films more readily facilitate penetration and binding of water to their surface in comparison to the denser DEGVE films. The difference in fouling properties identified through this comparative study has shown that % C-O-C retention may not alone be an indication of non-fouling behavior. Other factors such as polymer network structure may also play a crucial role in the prevention of surface fouling. The experimental process involved the reaction of 2-(2-(Vinyloxy)ethoxy)ethanol(cas: 929-37-3).Electric Literature of 929-37-3

Gordeev, Ivan; Simek, Milan; Prukner, Vaclav; Artemenko, Anna; Kousal, Jaroslav; Nikitin, Daniil; Choukourov, Andrei; Biederman, Hynek published an article in 2016, the title of the article was Deposition of poly(ethylene oxide)-like plasma polymers on inner surfaces of cavities by means of atmospheric-pressure SDBD-based jet.Quality Control of 2-(2-(Vinyloxy)ethoxy)ethanol And the article contains the following content:

The jet of reactive effluents produced by surface dielec. barrier discharge was used to deposit PEO-like plasma polymers from di(ethylene) glycol vinyl ether. The jet was confined within the hollow space of either circular cross-section with substrate placed perpendicular to the jet, or rectangular cross-section with the walls used as substrates. The best 67% retention of the ethers was obtained for the circular channel, whereas it was only 50% for the rectangular channel. In the latter case, deposition at longer distances was possible. In both cases, the deposition started with the formation of islands that grew, coalesced and eventually built up a continuous coating. The experimental process involved the reaction of 2-(2-(Vinyloxy)ethoxy)ethanol(cas: 929-37-3).Quality Control of 2-(2-(Vinyloxy)ethoxy)ethanol

On February 28, 2013, Magalhaes, Ana L.; Da Silva, Francisco A.; Silva, Carlos M. published an article.Product Details of 321-28-8 The title of the article was Free-volume model for the diffusion coefficients of solutes at infinite dilution in supercritical CO2 and liquid H2O. And the article contained the following:

A new free-volume model for tracer diffusion coefficients in supercritical CO2 and liquid water is proposed in this work. It embodies the concepts of free volume and activation energy. The free volume is calculated by the Carnahan-Starling expression, and the necessary effective hard sphere diameter was taken from a previous publication. The model is explicit, straightforward, contains one parameter per system (activation energy), and only requires temperature, solvent d., solute mol. weight, and the solvent LJ constants The validation of the model was accomplished with a large database, comprehending 289 systems with 5485 data points, and achieved only 3.56% of error. The fine predictive capability of the new expression was also demonstrated. The correlations of Wilke-Chang, Tyn-Calus, He-Yu-Su, Zhu et al., and Dymond were adopted for comparison, but provided much poorer results and/or prediction values. A spreadsheet for the calculation of D12 is given in Supplementary data. The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).Product Details of 321-28-8

Savini, Sara; Longo, Edoardo; Servili, Andrea; Murolo, Sergio; Mozzon, Massimo; Romanazzi, Gianfranco; Boselli, Emanuele published an article in 2020, the title of the article was Hypobaric packaging prolongs the shelf life of refrigerated black truffles (Tuber melanosporum).Reference of 1,2-Dimethoxybenzene And the article contains the following content:

Black truffle (Tuber melanosporum Vitt) is a fine agro-food product known for its unique aroma and very limited shelf life (maximum of 5-7 days, room temperature). Hypobaric packaging at 30 kPa, a mix of 1% O2/99% N2, and 40% CO2/60% N2 were studied to prolong the shelf life of black truffle at 4掳C in sealed polypropylene vessels, compared to normal atm. Epiphytic microbial population, firmness, weight loss, CO2 formation, and sensory properties were monitored weekly up to 35 days of storage and were related to the volatile profile. Principal components anal. revealed good correlation between the storage time and the decrease of firmness, and the increase of the microbial count and CO2 production Only truffles stored under hypobaric conditions showed an acceptable quality after 14 days storage. Hypobaric packaging is a cheap strategy to prevent the swelling of vessels caused by respiration and can reduce the deviation from the high-quality level of the fresh product from one to at least two weeks. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Reference of 1,2-Dimethoxybenzene
