Analysis of longitudinal vibration band gaps in periodic carbon nanotube intramolecular junctions using finite element method

AIP Advances, 2015
The longitudinal vibration band gaps in periodic (n, 0)–(2n, 0) single-walled carbon nanotube(SWCNT) intramolecular junctions(IMJs) are investigated based on the finite element calculation.

Nonlinear stability of a single-layer hybrid grid shell

Journal of Civil Engineering and Management, 2012
This paper presents a study of a hybrid grid shell, which is made of quadrangular meshes diagonally stiffened by pre-tensioned thin cables. The construction of the hybrid structure by translating a spatial curve against another spatial curve is firstly ...

Rethinking Charge Transport and Recombination in Donor‐Diluted Organic Solar Cells

Advanced Materials, EarlyView.
Organic solar cells with 1–45% PM6 content in Y12 were studied to link structure and charge dynamics to performance. The conductivity follows a 3D percolation model without a sharp threshold. Donor dilution preserves the photogeneration yield, but limits the fill factor due to transport resistance losses.

A numerical framework for form-finding of gridshells considering fabrication uncertainties [PDF]

MATEC Web of Conferences
The Force Density Method (FDM) is well-suited for generating statically admissible geometries of gridshells by controlling the so-called force densities, defined as the ratio between axial force and member length in each bar.

Wearable Morphology‐Adaptive in‐Ear Device With Active Cleansing Capability for Multimodal Health Monitoring

Advanced Materials, EarlyView.
We present SCIENCE, an in‐ear multimodal physiological monitor featuring two key innovations. Water‐triggered morphological expansion (a 2‐mm cylinder to a 9‐mm spindle) achieves conformal adaptation across complex canal geometries. Simultaneously, active biofouling mitigation disrupts cerumen barriers, reducing sensor‐skin impedance by 20%.
