Friction‐Assisted Liquid Metal‐Driven Anchoring of Low Redox Potential Metal Ions for Enhanced Electromagnetic Wave Absorption

open access: yesAdvanced Science, EarlyView.
Friction‐assisted liquid metal resolves the thermodynamic‐kinetic dilemma of low reduction potential (LRP) ions through shear‐induced electron generation, enabling efficient LRP reduction/anchoring while suppressing parasitic reactions. This approach synthesizes InGaZn5O8 crystals with unique electronic configurations, achieving a 5.92 GHz effective ...

Optical Force Monitoring in Polymeric Materials with a Coumarin‐Based Mechanophore

open access: yesAngewandte Chemie, EarlyView.
Coumarin dyes are reacted with acrylates to form a mechanophore via an accessible two‐step synthesis that exhibits exclusive responsivity to force. Mechanical deformation of polymeric materials functionalized with the mechanophore activates blue fluorescence visible to the naked eye, enabling the optical detection of force‐induced molecular damage in ...

Is sensitivity to xylem cavitation a relevant physiological trait for fodder production in dry season? [PDF]

open access: yes, 2013
In the Sahel parklands, trees can provide fodder during the dry season if they keep functional foliage. In such conditions, the xylem vessels sustain high tension which can induce cavitation, decrease the conduction of sap and lead to branch mortality ...

Moisture Harvesting by the Structure Regulation of Hygroscopic Hydrogel for Energy and Water Sustainability

open access: yesAdvanced Electronic Materials, EarlyView.
Hygroscopic hydrogels are capable of utilizing the moisture from air, which can transfer the gaseous water to liquid by a surface phase transition. Taking advantage of this water, sustainable water production, thermal management, and electricity generation can be realized.

Force‐Induced Ring Flipping in a Threaded Pillar[5]Arene

open access: yesAngewandte Chemie, EarlyView.
Mechanical force was used to flip the orientation of a hydroquinone ring in a threaded pillar[5]arene to reach an elusive conformation not accessible to other methods of activation. The flipping can be suppressed with large substituents on the axle or the macrocycle.

Harnessing the Biological Responses Induced by Nanomaterials for Enhanced Cancer Therapy

open access: yesAggregate, EarlyView.
Nanomaterial (NM)‐induced toxicity can be strategically repurposed for cancer therapy. This review summarizes the mechanism by which NMs selectively activate specific cellular processes to regulate cell fate independently. We also discussed how NMs‐induced biological responses can be leveraged as therapeutic strategies for cancer treatment.
