MOF‐Derived Superaerophobic Ni‐CoOOH Nanosheet Anchored on Stretched Carbon via In Situ Morphology Reconstruction for Durable Oxygen Evolution

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study constructed an in situ superhydrophobic OER catalyst with excellent activity and durability. Ni‐Co expansion induced tensile strain, converting the polyhedral framework into vertical nanosheets that enhance intrinsic activity and bubble detachment.

Chemically Modular, Nonfluorinated Polymer Adsorbents for Capturing Per‐ and Polyfluoroalkyl Substances (PFAS)

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Nonfluorinated polymer networks for PFAS adsorption are synthesized using active ester click chemistry. Incorporating Lewis base ligands along with hydrophilic and hydrophobic co‐monomers leads to high PFOA binding efficiency. Ligand basicity and pH are found to play an important role in PFOA sorption.

Structural Effects of Vertical Non‐Skeletal Elements (NSEs) With Rocking Mechanisms

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This paper introduces the structural effects provided by vertical non‐skeletal elements (NSEs), such as claddings and partitions, with vertical slotted holes at their supports to enable rocking as the frame undergoes significant lateral deformation.

Gait alterations increase friction of degenerated articular cartilage: A tribological study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To investigate the effect of gait alterations associated with osteoarthritis (OA) on the frictional properties of porcine articular cartilage (AC) in intact and degenerative conditions. Methods Forty‐eight cylindrical AC samples were harvested from 12 porcine femur condyles and equally divided between four groups with n = 12 samples ...

Managing the meniscus part I—Anatomy, biomechanics, and treatment strategies for the atraumatic meniscus tear

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The purpose of this article is to serve as the first of a two‐part review on the meniscus; in this review, we will establish the background on anatomy and pathogenesis of the meniscus, as well as the effect of the meniscus on native knee kinematics and function.

Bucket‐handle and medial meniscal tears exhibit higher failure rates after all‐inside repair with concomitant ACL reconstruction

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To evaluate failure rates across specific meniscal tear morphologies in patients undergoing all‐inside meniscal repair with anterior cruciate ligament reconstruction (ACLR), and to identify factors associated with failure. Methods This retrospective cohort included 1355 patients who underwent all‐inside meniscal repair during ACLR ...
