Programmable Soft Actuator with Multi‐Responsiveness Based on Conductive MOF‐Liquid Crystal Polymer Composite

open access: yesAdvanced Functional Materials, EarlyView.
A sequential dual‐alignment strategy independently programs the orientation of conductive metal‐organic framework (c‐MOF) microrods and liquid crystals within a composite film. This approach creates an asymmetric bilayer structure that enables precise, multi‐responsive actuation.

Excessive external rotation is needed for valgus knee TKA.

open access: yes, 2018
(A) The surgical transepicondylar axis (solid line) connects the medial sulcus to the lateral epicondyle. The posterior condylar axis (dashed line) is the tangent of the posterior part of the medial and lateral condyle.

2D Skeletal Muscle Thin Film Actuators Enhance Efficiency of Biohybrid Robots

open access: yesAdvanced Functional Materials, EarlyView.
2D skeletal muscle thin film actuators generate millinewton‐scale forces and millimeter‐scale strokes while remaining functional for over 30 days. Their force density is 20‐fold higher than 3D skeletal muscle actuators, enabling multi‐fin robots with tunable speed and multidirectional steering.

The Impact of Auditor Rotation on the Audit Quality: A Field Study from Egypt [PDF]

open access: yes
Lack of audit quality and subsequent audit failures result mainly from a lack of independence which is considered to be a consequence of the extended auditor client relationship.

Whole-rotation dry matter and nitrogen grain yields from the first course of an organic farming crop rotation experiment [PDF]

open access: yes, 2002
The possibilities for increasing total grain yield in organic cereal production through manipulation of crop rotation design were investigated in a field experiment on different soil types in Denmark from 1997 to 2000.

Dimensionality‐Driven Interfacial Electronic Coupling in Carbon‐Supported Gd‐CuO Catalysts for Selective CO2 Electroreduction to Ethylene

open access: yesAdvanced Functional Materials, EarlyView.
The 2D carbon‐supported Gd–CuO exhibits strong interfacial electronic coupling, abundant oxygen vacancies, and highly exposed active sites, enabling efficient CO enrichment and C─C coupling toward selective and durable CO2‐to‐C2H4 conversion. ABSTRACT Copper‐based catalysts are promising for electrochemical CO2 reduction toward value‐added chemicals ...

Three-dimensional comparative strain analysis of the capsuloligamentous complex during passive glenohumeral motion

open access: yesJournal of Orthopaedic Surgery and Research
Background Understanding the three-dimensional biomechanical behavior of the capsuloligamentous complex, considering it as a single sheet of fibrous tissue, is beneficial for assessing patients with limited glenohumeral range of motion in vivo.
