Beyond Dexterity: Navigating the Trade‐Offs of Steerable Catheter‐ and Guidewire‐Based Endovascular Robotics for Clinical Applications

open access: yesSmartBot, EarlyView.
Steerable catheters and guidewires enable precise navigation and intervention in complex vascular anatomies. This review systematically examines their steering mechanisms, including morphological, transmission‐based, and transduction‐based actuation, highlighting their underlying principles and engineering characteristics.

Liquid‐Processed 2D Aromatic Amorphous Carbon: Defect Engineering and Universal Transport Scaling

open access: yesSmall, EarlyView.
Liquid‐processed graphene oxide (GO) thin films undergo a controllable crystalline–to–amorphous transition driven by thermal quenching. By kinetically tuning oxygen‐driven defect formation during reduction, scalable 2D aromatic amorphous carbon phases are stabilized, directly linking nanoscale disorder and defect topology to electronic transport ...

Direct voltage control of magnetorheological damper for vehicle suspensions

open access: yes, 2013
The paper presents a study on the direct voltage control of a magnetorheological (MR) damper for application in vehicle suspensions. As MR damper dynamics is highly nonlinear, the direct control system design for an MR damper is difficult. Representing

Advances in research on layered double hydroxides for biomedical applications

open access: yesSmart Molecules, EarlyView.
Layered double hydroxides (LDHs) are pH‐responsive nanomaterials with broad biomedical applications. This review summarizes LDH synthesis methods and compares their advantages. It highlights LDHs' progress in cancer therapy, including chemo‐photothermal, chemo‐immunotherapy, and photodynamic‐immunotherapy combinations and their potential in bone repair.

Establishment of a Human Cell‐Based In Vitro Test System for Investigating and Evaluating Cytotoxic and Immunomodulatory Effects of Indoor Mold

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Mold growth in damp indoor environments is a widespread problem associated with respiratory health effects, though causal mechanisms remain incompletely understood. We established a human cell‐based in vitro test system using bronchial epithelial cells (NuLi‐1) and macrophages (THP‐1) to assess inhalation toxicity and immunomodulatory effects ...

Metabolome Diversity Enhances Resistance of Intertidal Clams to Thermal Stress

open access: yesIntegrative Zoology, EarlyView.
Meretrix species are widely distributed intertidal bivalves in China with significant ecological and economic importance, which are sensitive to thermal stress. Our results showed that thermal environments of clam habitats shaped metabolome diversity, which can enhance the resistance of intertidal clams to thermal stress.

Stimulant Persistence in Adult ADHD: A Retrospective Analysis of a Large Clinical Cohort

open access: yesActa Psychiatrica Scandinavica, EarlyView.
ABSTRACT Introduction Network meta‐analyses suggest dexamphetamines (dAMP) may yield more favourable short‐term outcomes than methylphenidate (MPH) in adults with ADHD, yet evidence on long‐term comparative persistence remains scarce. This study compared 12‐month treatment persistence between MPH and dAMP in a large multicentre cohort and explored ...

New Non-Linear Modeling and Optimal Controlling for MR Damper under Impact Load

open access: yes, 2011
Magnetorheological (MR) fluid is capable of changing its rheological characteristics under magnetic field. Controllability is one of the advantages of MR damper.
