Ion sensing pencil: Draw your own sensor

نویسندگان

چکیده

We demonstrate for the first time concept of ion sensing pencil (ISP). The pencil’s lead carries chemical functionality and is constructed by compression graphite zeolite, while clutch prepared 3D printing. ISP can be used to draw a sensor simple abrasion onto hydrophobic surface. stored at home, immediately off-the-shelf without any handling prior measurements. It’s preparation, handling, measuring protocols offer possibility integration into large scale networks or offered general public use home using readout devices already present many homes. producing 14 ISPs one different zeolites individually in 60:40 wt%. These are then electrodes which were characterized analogy ion-selective electrodes. ISP-drawn utilized as multi-sensor array determination water quality model sample, reported case zeolite-based multisystem arrays, followed demonstration their potential non-trained personnel. implementation potentiometric detection holds promise further development inexpensive accessible tools obtaining information areas where utilization sensors currently limited.

Draw Your Own Story: Paper and Pencil Interactive Storytelling

In this paper, we present a storytelling system able to dramatize interactive narratives in augmented reality over a conventional sheet of paper. The system allows users to freely interact with virtual characters by sketching objects on the paper. Users interacting with the system can indirectly affect the characters' decisions, even to the point of radically subverting the storyline.

Empirical Algorithmics: draw your own conclusions

In an empirical comparisons of algorithms we might compare run times over a set of benchmark problems to decide which one is fastest, i.e. an algorithmic horse race. Ideally we would like to download source code for the algorithms, compile and then run on our machine. Sometimes code isn't available to download and sometimes resource isn't available to implement all the algorithms we want to stu...

Grow-your-own synapses

cientists have discovered a new function for amyloid precursor protein (APP), a protein linked to Alzheimer’s disease. The finding may reveal how APP gets mixed up with the enzymes that make it go bad. APP has an evil reputation. The and secretases transform it into amyloidpeptide, a component of the plaques that riddle the brain in Alzheimer’s disease. Previous work by Larry Goldstein (Univesi...
