Omnidirectional and Multi‐Material In Situ 3D Printing Using Acoustic Levitation

open access: yesAdvanced Materials Technologies, EarlyView.
An acoustophoretic 3D fabrication system enabling omnidirectional, multi‐material in situ printing is presented via acoustic levitation. Utilizing a phased array of transducers (PAT), it generates acoustophoretic forces for levitating and transporting materials in mid‐air, allowing precise, contactless, and voxel‐by‐voxel printing onto complex ...

Food Security Modelling [PDF]

open access: yesBiosciences, Biotechnology Research Asia, 2015
A focus of the paper is a problem of "observability" regarding food security. Known scientific approaches to identification of a similar condition have not provided us with a grounded solution to refer to actual borders of security (or standards of mutual penetration). Their absence makes methodological capacities of modelling essentially disturbed. It

Anti‐Counterfeiting Tags with Camouflaged QR Codes on Nanocavities, Using Polymer‐Dispersed Liquid Crystals

open access: yesAdvanced Materials Technologies, EarlyView.
A QR code, printed through a commercial printer on a thin plastic foil, pre‐coated with a nanocavity is proposed as an anti‐counterfeiting label. Nanocavity imparts distinctive optical properties in terms of light reflection and transmission. A thin layer of polymer‐dispersed liquid crystals (PDLC) is used to camouflage the QR code, that become ...
