Wearable Haptic Feedback Interfaces for Augmenting Human Touch

open access: yesAdvanced Functional Materials, EarlyView.
The wearable haptic feedback interfaces enhance user experience in gaming, social media, biomedical instrumentation, and robotics by generating tactile sensations. This review discusses and categorizes current haptic feedback interfaces into force, thermal, and electrotactile stimulation‐based haptic feedback interfaces, elucidating their current ...

Electroplating of Wear‐ and Corrosion‐Resistant CrCoNi Medium‐Entropy Alloys beyond Hard Chromium Coatings

open access: yesAdvanced Functional Materials, EarlyView.
The electroplating of a CrCoNi medium‐entropy alloy is achieved using a mixture of an ionic liquid and an aqueous solution containing metal salts. The CrCoNi medium‐entropy alloy thin film exhibits high wear and corrosion resistance superior to conventional hard chromium coatings. Abstract High‐entropy alloys (HEAs) and medium‐entropy alloys (MEAs) are

Development of a Novel, All‐Aromatic High Tensile Modulus Liquid Crystalline Polyimide for Fused Filament Fabrication Applications

open access: yesAdvanced Functional Materials, EarlyView.
A novel, high tensile modulus, fully aromatic thermotropic liquid crystalline polyimide (LCPI) with better solvent resistance and thermal stability is synthesized. Tensile specimens are fabricated using both injection molding and FFF processes, accomplished via lower viscosity enabled by the LC phase.

3D In Vitro Glioma‐Neuron‐Astrocyte Biomimetic Composites Recapitulate Key Molecular Mechanisms Linked to Glioblastoma Multiforme Pathophysiology

open access: yesAdvanced Functional Materials, EarlyView.
Glioblastoma multiforme is the most devastating and incurable brain tumor. To better study this disease, a 3D model is developed using a hyaluronic acid‐based hydrogel combined with a multicellular approach. This model recapitulates in vivo brain stiffness, cell‐extracellular matrix and cell‐cell interactions and the tumor's hijacking function with the

Superlubricious Surfaces Through Surface Attached Hydrogels Obtained by C,H‐insertion Crosslinking

open access: yesAdvanced Functional Materials, EarlyView.
Taking synovial joints as a source of inspiration, the friction properties of surfaces covered with 1d‐swelling polyelectrolyte hydrogels in combination with a shear‐thinning aqueous lubricant are studied. Such systems obtained by C,H insertion crosslinking show superlubricious behavior, even surpassing the friction values reported for the natural ...

Bi‐Directional Assembly of Boron Nitride µ‐Platelets by Micro‐Molding for Advanced Thermal Interface Materials

open access: yesAdvanced Functional Materials, EarlyView.
Bi‐directionally assembled BN µ‐platelets in micropatterns formed by a micro‐molding method for thermal interface materials are demonstrated. The BN µ‐platelets are vertically aligned selectively, while compressed regions without patterns accommodate horizontally assembled BN µ‐platelets. Through anisotropic orientation, high thermal conductivities for

The entropic quasi-de Sitter instability time from the distance conjecture

open access: yesPhysics Letters B, 2020
From the entropy argument for the dS swampland conjecture which connects the Gibbons-Hawking entropy bound with the distance conjecture, we find the entropic quasi-dS instability time given by 1/(ϵHH)log⁡(mPl/H) as the lifetime of quasi-dS spacetime.
