Undergraduate nursing programs typically include students with limited 'on-campus' time who need learning resources that are flexible, technologically appropriate, remotely-accessible (mobile smart devices), and above all, engaging. This has presented academics with challenges surrounding institutional security firewalls, password-access requirements, intellectual property/ownership and staff/student privacy. To overcome these challenges a collection of evidence-based YouTube videos, posted on the Biological Sciences YouTube Channel, supported by the Biosciences in Nurse Education, and underpinned by Benner's pedagogical framework, were developed with the intention of moving students from novice to competent clinical bioscience users...

Wearable devices and systems demand multifunctional units with intelligent and integrative functions. Smart fibers with response to external stimuli, such as electrical, thermal, and photonic signals, etc., as well as offering energy storage/conversion are essential units for wearable electronics, but still remain great challenges. Herein, flexible, strong, and self-cleaning graphene-aerogel composite fibers, with tunable functions of thermal conversion and storage under multistimuli, are fabricated. The fibers made from porous graphene aerogel/organic phase-change materials coated with hydrophobic fluorocarbon resin render a wide range of phase transition temperature and enthalpy (0-186 J g-1 )...

The impact of the Internet on education has been recognized for decades, and as technology advances, the ways in which students can access Internet content is ever increasing. Most students have some kind of portable smart device with which they access Internet content without the locational constraints of a desktop computer. This mobility has prompted abundant literature suggesting ways that Quick Response Codes (QR codes), a kind of two dimensional barcode, could be used to advance student learning. However, very few studies have tested the usefulness of QR codes in undergraduate science classes...

In this work, a bistable polymer framework liquid crystal (PFLC) thin film by thermal curing of epoxy monomers with two different thiols, a traditional flexible-structure thiol and a novel original rigid-structure thiol has been successfully fabricated, combining a novel mixed morphology of polymer matrix and cholesteric liquid crystals with negative dielectric anisotropy. The polymer framework morphology has been presented by curing two types of epoxy monomers with two types of thiols, and the liquid crystals tend to be focal conic textures with large size domains at the initial state in the PFLC film, so that it has a moderate light transmissivity at this state between the transparent state and the opaque state...

The Internet of Things (IoT) utilizes algorithms to facilitate intelligent applications across cities in the form of smart-urban projects. As the majority of devices in IoT are battery operated, their applications should be facilitated with a low-power communication setup. Such facility is possible through the Low-Power Wide-Area Network (LPWAN), but at a constrained bit rate. For long-range communication over LPWAN, several approaches and protocols are adopted. One such protocol is the Long-Range Wide Area Network (LoRaWAN), which is a media access layer protocol for long-range communication between the devices and the application servers via LPWAN gateways...

A monolith photodetector is presented that utilizes the material properties of MAPbI3 perovskite for self-powered operation and achieves improved stability by composting with polystyrene. The self-powered operation makes this device suitable for remote applications and in smart systems. Improved stability of more than 20 days, with performance maintained by over 80% under ambient conditions, is achieved by incorporating polystyrene without additional fabrication steps. A plain MAPbI3 device in comparison shows a performance degradation of 70-85% within 4 days of operation...

The interactions between two or more molecules or colloidal particles can be used to obtain a variety of self-assembled systems called supramolecules or supracolloids. There is a clear, but neglected, convergence between these two fields. Indeed, the packing of molecules into colloidal or supracolloidal particles emerges as a smart solution to build an infinite variety of reversible systems with predictable properties. In this respect, the molecular building blocks are called "tectons" whereas "colloidal tectonics" describes the spontaneous formation of (supra)colloidal structures using tectonic subunits...

Active switching glazings driven by electrical energy have been widely used for the on-demand control of the optical transmittance of smart windows; however, continuous electrical energy consumption is necessary to maintain the optical state. In this work, to minimize the energy consumption during operation of switchable windows, we have developed an optically bistable switching glazing based on the memory function in the volume change of the hydrogels. By grafting a multi-component copolymer that has a chemical composition gradient of three different monomers onto the methyl cellulose backbone, the prepared hydrogel exhibits a smooth transition during heating and a large thermal hysteresis in the swelling behavior during cooling...

A smart synthetic method is conceived to construct large batches of ZnO nanostructures to meet market demand for light-emitting diodes. Utilizing the localized surface plasmon resonance of metal nanoparticles (NPs) facilitates the recombination of electron-hole pairs and the release of photons. Compared to raw ZnO nanorods (NRs), ZnO NRs@HfO2@Al NPs show a ~120× enhancement in ultraviolet photoluminescence (PL), while ZnO NRs@HfO2@Ag NPs show a six-fold enhancement. Because the surface plasmon energy of Al is nearer the ZnO band gap, the PL enhancement of ZnO NRs covered with Al is stronger than that of those covered
 with Ag...

Introduction: Electronic nicotine delivery systems (ENDS) are used to aid smoking cessation attempts; however, many smokers continue to smoke while using an ENDS (dual use). Although uncertainty remains regarding whether specific ENDS patterns hinder or support successful smoking cessation, recent advances in "smart" technology allow passive and active recording of behaviors in real time, enabling more detailed insights into how smoking and vaping patterns may coevolve. We describe patterns of ENDS initiation, and subsequent use, including any changes in cigarette consumption, among daily smokers using a "smart" ENDS (S-ENDS) to quit smoking...

As Internet of Things (IoT) devices and other remote patient monitoring systems increase in popularity, security concerns about the transfer and logging of data transactions arise. In order to handle the protected health information (PHI) generated by these devices, we propose utilizing blockchain-based smart contracts to facilitate secure analysis and management of medical sensors. Using a private blockchain based on the Ethereum protocol, we created a system where the sensors communicate with a smart device that calls smart contracts and writes records of all events on the blockchain...
