Acoustic Impedance‐Tailored High‐Performance Ultrasound‐Driven Triboelectric Nanogenerators

open access: yesAdvanced Energy Materials, EarlyView.
An acoustic impedance–mismatched triboelectric nanogenerator is presented for efficient ultrasound energy harvesting in implantable medical devices. Concave and convex membrane patterning induces controlled acoustic impedance mismatch, which boosts output by ∼200% and ensures stable operation over 100 million cycles and six weeks in vivo, highlighting ...

Redefining Crystalline Silicon: Unlocking New Horizons in Transparent and Flexible Photovoltaics

open access: yesAdvanced Energy Materials, EarlyView.
Crystalline silicon is presented as a platform for transparent and flexible photovoltaics. This review article outlines design principles for optical strategies to fabricate transparent silicon solar cells, mechanical strategies that mitigate silicon brittleness, and emerging concepts such as singlet‐fission spectral conversion and tandem architectures,

A high resolution shock capturing scheme for high Mach number internal flow [PDF]

open access: yes
An accurate shock capturing scheme is developed for high speed flow. The flux limited dissipation scheme can be converted to a symmetric TVD scheme in the case of a scalar conservation law.

A Unifying Approach to Self‐Organizing Systems Interacting via Conservation Laws

open access: yesAdvanced Intelligent Discovery, EarlyView.
The article develops a unified way to model and analyze self‐organizing systems whose interactions are constrained by conservation laws. It represents physical/biological/engineered networks as graphs and builds projection operators (from incidence/cycle structure) that enforce those constraints and decompose network variables into constrained versus ...

Fermion Virtual Effects in $e^+ e^- -> W^+ W^-$ Cross Section

open access: yes, 1996
We analyse the contribution of new heavy virtual fermions to the $e^+e^- \rightarrow W^+W^-$ cross section. We find that there exists a relevant interplay between trilinear and bilinear oblique corrections.

Towards Advanced Intelligent and Perceptive Soft Grippers

open access: yesAdvanced Intelligent Systems, EarlyView.
Implementing soft yet strong and intelligent soft grippers request innovative and creative solutions in designing soft bodies and seamlessly integrating actuated systems with hierarchical sensing. This review systematically analyses soft grippers with a deep understanding of core components, from fundamental design principles to actuation and sensing ...

Vascular Abnormalities in Hypermobile Ehlers–Danlos Syndrome: A Retrospective Cohort Study

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Hypermobile Ehlers–Danlos syndrome (hEDS), while generally free from severe vascular complications, may occasionally present with cardiac and vascular abnormalities that warrant specific investigation. While studies have been conducted on the prevalence of cardiac involvement, none have focused on vascular aspects. This retrospective study was
