Carboxylic‐Acid Functionalized Multiwalled Carbon Nanotube‐Alkane‐Based Resistive Temperature Sensor for Cold Chain Applications

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents a reversible temperature sensor with high switching ratio, ∼103. The device is fabricated using PET‐ITO and carbon nanotube dispersions in alkane. Considering its application in cold chain logistics, a proof‐of‐concept with LED is showcased. Thus, a temperature drop below the threshold temperature (crystallization temperature of the

Thresholds for pressure and sharpness in the right and left hands

open access: yesCortex, 1969
Summary The question of lateral differences in tactile sensitivity among normal persons has been the subject of a number of recent studies. These studies, in which thresholds for tactile pressure were determined by the von Frey method, have yielded inconsistent results; some have reported higher sensitivity of the left side while others have found no

Optical isolation with nonlinear topological photonics

open access: yesNew Journal of Physics, 2017
It is shown that the concept of topological phase transitions can be used to design nonlinear photonic structures exhibiting power thresholds and discontinuities in their transmittance. This provides a novel route to devising nonlinear optical isolators.

Evaluating Energy Absorption Performance of Filled Lattice Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

Sharp dual-regime thermal transition driven by bead morphology in metal fused filament fabrication: bead-resolved digital twin analysis

open access: yesVirtual and Physical Prototyping
This work develops a GPU-accelerated, bead-resolved digital twin for FFF that reconstructs super-elliptic filament geometries from G-code and simulates transient heat transfer via voxel-level activation synchronised to deposition order.
