هدف: شناسائی عملکرد پلیمر کلوسل‌جی با افزودن نانوالیاف سلولزِ BCN[1] و NFC[2] در دمای نرم‌شوندگی (Tg) با هدف ایجاد مادۀ پلیمری اصلاح‌شده برای مرمت آثار کاغذی. روش٫ رویکرد پژوهش: داده‌ها با استفاده از گرماسنج روبشی تفاضلی (DSC)[3] به روش استاندارد ASTM[4] گردآوری و با استناد به تجربیات آزمایشگاهی مرتبط تحلیل و تفسیر شده‌است.<br ...
Near Field Communication (NFC) is a technology that enables a device to communicate with another at a maximum distance of around 20cm or less. Currently, mobile phone manufacturers , financial organisations and mobile network providers are attempting to apply this technology to Smartphones and other handheld devices because of the opportunity to enable the consumer to use commercial services mo...
DASH7 and NFC (Near Field Communications) complement each other extremely well, as their features and functionality are completely different, but their technologies are suprisingly similar. This whitepaper describes the technical feasibility of integrating DASH7 components with NFC components and touches upon the functionality afforded by such an integrated solution. © Copyright 2012 Haystack T...
Near Field Communication (NFC) is an RF-based proximity coupling technology allowing transaction within a range of up to 10 cm. Whereas the physical and the data link layer of NFC are already standardized by ISO, ECMA and ETSI, it’s the NFC-Forum’s task to get a common agreement on data protocols, security measures and layers above. The NFC-Forum is a non-profit industrial consortia cooperating...
—Near Field Communication (NFC) is deemed to be a future technology with a lot of potential in many areas. One of those areas, learning and teaching, will be covered in this article, showing possible usages of NFC with teaching and learning materials. With a lot of new NFC capable devices presented recently, this technology can be utilized in many areas, including the arbitrarily growing field ...
A novel kind of nanofibrillated cellulose (NFC) reinforced polyvinyl butyral (PVB) nanofibers-containing bilayer hydrogel system was successfully fabricated via the combination of a one-step, in-situ, free radical polymerization and electrospinning. The hydrogel owned high mechanical strength, thermoresponsive, and near infrared bending/unbending properties. The cross-linking density of hydroge...
Near Field Communication (NFC) is a Radio Frequency (RF) technology that allows data to be exchanged between devices that are in close proximity. An NFC-based mobile coupon (M-coupon) is a coupon that is retrieved by the user from a source such as a newspaper or a smart poster and redeemed afterwards. The M-coupon is a cryptographically secured electronic message with some value stored on user’...
This study explores the possibility of enhancing both mechanical and breakdown properties of insulating presspaper by the introduction of an organic nano additive. Four different concentrations of nanofibrillated cellulose (NFC) were taken into account: 0.5 wt %, 2.5 wt %, 5 wt %, and 10 wt %. Presspaper containing no NFC was also prepared as a reference. Obtained samples were characterized by ...
BACKGROUND/AIMS Nailfold capillaroscopy (NFC) has been used to examine morphological and functional microcirculation changes in connective tissue diseases. It has been demonstrated that NFC patterns reflect abnormal microvascular dynamics, which may play a role in fibromyalgia (FM) syndrome. The aim of this study was to determine NFC patterns in FM, and their association with clinical features ...
The inductive link is widely used in implantable biomedical sensor systems to achieve near-field communication (NFC) and wireless power transfer (WPT). However, it is tough to achieve reliable NFC on an inductive WPT link when the coupling coefficient is ultra-low (0.01 typically), since the NFC signal (especially for the uplink from the in-body part to the out-body part) could be too weak to b...
