Controlled ripening of climacteric fruits, such as bananas and avocados, is a critical step to provide consumers with high-quality products while reducing postharvest losses. Prior to ripening, these fruits can be stored for an extended period of time but are usually not suitable for consumption. However, once ripening is initiated, they undergo irreversible changes that lead to rapid quality l...
The molecular building block approach was employed effectively to construct a series of novel isoreticular, highly porous and stable, aluminum-based metal-organic frameworks with soc topology. From this platform, three compounds were experimentally isolated and fully characterized: namely, the parent Al-soc-MOF-1 and its naphthalene and anthracene analogues. Al-soc-MOF-1 exhibits outstanding gr...
BACKGROUND Among the very elderly, poor oral health reduces life expectancy. In this study, differences in the magnitude of the maximum occlusal force (MOF) in the very elderly were examined in terms of effects on all-cause mortality in a 3-year follow-up. METHODS We evaluated 489 community-living elderly individuals aged 85 years or older. MOF was measured using an occlusal force measuring d...
BACKGROUND It has been suggested that severity of the immune response induced by immune cells is associated with morbidity and mortality from acute pancreatitis. The authors investigated and evaluated the relationship between distinct peripheral lymphocyte subsets at admission and clinical outcome prior to hospital discharge so as to find a predictor to the prognosis of acute pancreatitis in ly...
HYPOTHESIS Abdominal compartment syndrome (ACS) is a morbid complication of damage-control laparotomy. Moreover, the technique of abdominal closure influences the frequency of ACS. DESIGN Retrospective cohort study. SETTING Urban level I trauma center. PATIENTS We studied 52 patients with trauma who required damage-control laparotomy during the 5 years ending December 31, 1999, and who su...
چارچوبهای آلی کووالانسی دسته منحصر بهفردی از پلیمرهای بلوری متخلخل هستند که صرفاً با پیوندهای کووالانسی برگشتناپذیر عناصر سبک (مانند کربن، بور، اکسیژن، سیلیکون، نیتروژن و سایر) با واحدهای ساختاری آلی تشکیل شدهاند. این پلیمرهای آلی متخلخل ویژگیهای منحصر به فردی را نشان میدهند. بدین سبب قابلیت استفاده در کاربردهای مختلف صنعتی را دارند. ساختارهای آلی فلزی و آلی بهدلیل ویژگیهای شاخصی مانند س...
تثبیت مؤثر نانو ذرات، بخصوص نانو ذرات اکسید فلزی بر سطح پایه کاتالیستهای مختلف شامل پایه کاتالیستهای آلی، معدنی و یا آلی- معدنی یکی از روشهای مناسب برای بهبود خواص نانو ذره و نیز افزایش بهرهوری از کاتالیستهاست. در این مقاله، نانو ذرات کروی α-Fe2O3 با بهرهگیری از روش پراکندگی در حالت جامد (SSD) بر سطح سیلیس معدنی به عنوان یک پایه کاتالیست تثبیت شدند. تمامی محصولات از طریق آنالیز فلوئورسانی ...
Constructing MOF-on-MOF heterojunction with elaborate charge transfer mechanism and interface is a promising strategy for improving the photocatalytic properties of MOFs. Herein, Step-scheme (S-scheme) MIL-125-NH2@CoFe Prussian blue analogue (PBA) reported first time. The heterostructure exhibits sandwich-like morphology hollow CoFe PBA nanocages selectively assembled on top-down surfaces MIL-1...
In the present study, a nanoporous metal organic framework (MOF) based on iron metal and amino terephthalate ligand MIL-101-NH2-Fe has been used as a carrier for loading and in vitro release of 5-flurouracil (5-FU) anticancer drug. The 5-FU drug loaded MOF was 13 wt % by using thermogravimetric analysis (TGA). The 5-FU release was monitored under physiological condition at 37°C, pH 7.4 in simul...
The use MOF-508a as sensing component for the precise discerning of bisphenol A via the electrochemical technique and its synthesis by a simple method were reported in the present study. Scanning electron microscopy (SEM) and x-ray diffraction (XRD) were applied to describe the MOF-508a’s composition and structure. In addition, MOF-508a was exploited so that the glassy carbon electrode could be...
