About Time and Eternity

, 1992
This paper is a set of thoughts about time, eternity and their nature. We give a work definition of time and the flow of time. We prove that, in order that a man can create and have consciousness, a future and a past must be disjoint space-time areas ...

Minimally Invasive Delivery of Optical Nanosensors Using Injectable Hydrogels

Advanced Materials Interfaces, EarlyView.
Injectable peptide hydrogels offer a minimally invasive delivery platform for single‐walled carbon nanotube (SWCNT)‐based near‐infrared fluorescent sensors, enabling real‐time measurement of drug concentrations. Encapsulated SWCNTs show a dose‐dependent fluorescence response across physiologically relevant concentrations and retain their fluorescence ...

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Time/Temporality/Eternity

, 2015
Time (Tid - noun), Temporality (Timelighed - noun), Eternity (Evighed - noun). The Danish 'Tid' is derived from the Old Danish 'tith' and the Old Norse 'tio'. From the same root, English derives "tide" (cf. "yuletide").

Chemically Doped Conductive Polymers for Wearable Health Monitoring

Advanced Materials Technologies, EarlyView.
Among conductive polymers, poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), polyaniline (PANI), and polypyrrole (PPy) are the most studied and applied. Chemical doping significantly boosts intrinsic conductivity and mechanical robustness.

Record Performance in Vertically Stacked, Solution‐Processed ZTO Schottky Diodes

Advanced Materials Technologies, EarlyView.
Schottky diodes based on solution processed sustainable zinc—tin–oxide thin films present an eco‐friendly and versatile alternative to conventional CMOS based technologies. Beyond state‐of‐the‐art performance for vertically stacked solution‐based oxide diodes was achieved, including rectification ratios exceeding nine orders of magnitude, and intrinsic

Material Selection and Geometric Design for Few‐filament Shape Memory Polymer Yarns for Force Generation

Advanced Materials Technologies, EarlyView.
A custom shape memory polymer material selection process relates quantitative application criteria (e.g., compression garment yarns) to material characterization information. The selected materials are manufactured into yarn geometries, which expand the design space by creating structural stress‐strain profiles beyond the nominal material stress‐strain
