This study applied a 3D additive manufacturing technique to produce a stable and high performance Mg-Ni alloy anode for lithium ion batteries. This 3D process used Mg-Ni powders to printed two layers on copper foil to obtain the Mg-Ni anodes directly, the 3D printed anodes have not need the traditional stir-slurry, coating and baking processes, and process the performances of high efficiency and low coat. Experiment results show that Mg 2 Ni, MgNi 2 and Mg 2 Cu intermetallic compounds (IMC) are benefit for 3D printed anode, the anode can slowly form a dense and thick SEI layer at 55°C high temperature charge-discharge; therefore, a better capacity than at 25°C can be achieved. The 85°C chargedischarge environment makes the volume expansion effect serious, which results in capacity decay slightly. The presented high temperature charge-discharge capacities are higher than that of the commercial lithium battery, demonstrate that 3D additive manufacturing can fabricate the novel alloy electrodes simply and quickly, and that 3D Mg-Ni anodes are very suitable for today's high-end electronic products.
Today, one may no longer alive but his social networking sites (SNS) account will still live on. Empirical studies on death and SNS started since 2004 covering issues on grief, bereavement, mourning, relational continuity functions of SNS, and digital legacy. Majority of them applied content and discourse analyses on SNS messages directed to or related to the deceased. Applying McLuhan’s aphorism medium is the message, researcher focused on the interplay among forms and functions of Facebook (FB) as a medium and message that mediates grief and the bereaved persons who are communicators that decided to grieve on FB. This research adopts grounded theory approach where in- depth interviews with 10 bereaved persons who maintain relational continuity with their deceased loved ones through FB were conducted. The conclusions are drawn to prove that bereaved users preferred to engage in a transcoporeal mediated communication with deceased for continuing bonds due to four main reasons – the deceased are perceived “dead but they are not”; maintaining relational continuity via FB is essential to “finish their unfinished business”; they felt aided and embraced when adopting “FB the Public Platform for Private Grief”, and they imagined a mutual communication based on “past experience and religious belief”. The mediated transcopereal communication (TcC) is enabled because the social medium (FB) is the message.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
