Mode‐Resolved Phonon Dynamics Under Chemical Pressure in SnTe Thermoelectrics

open access: yesAdvanced Science, EarlyView.
Chemical pressure reshapes low‐energy optical phonons in SnTe, altering their dispersion and scattering with heat‐carrying acoustic modes. Positive and negative pressure states modify phonon frequencies and lifetimes in distinct ways, revealing how mode‐selective lattice perturbations regulate acoustic–optical interactions and suppress lattice thermal ...

Rapid Solidification Brings Ultralow Thermal Conductivity and Superior Thermoelectric Performance for Intrinsic GeTe Alloy

open access: yesAdvanced Science, EarlyView.
Rapid solidification with glass fluxing is first applied to the intrinsic GeTe alloy and achieves large undercooling within 2 h. This enables partial retention of the high‐temperature cubic phase at room temperature and forms a crystallographically oriented α+β dual‐phase structure and a hierarchical defect network.

Nanocatalytic Immunotherapy Targeting Tumor‐Resident Intracellular Bacteria for Triple‐Negative Breast Cancer Treatment and Metastasis Suppression

open access: yesAdvanced Science, EarlyView.
Bacteria residing within tumor cells contribute to breast cancer progression, but few therapies target their elimination. FeSe2 nanosheets coated with cancer cell membranes accumulate in tumors and generate reactive oxygen species under ultrasound, killing tumor cells and their harbored bacteria at the same time.

Al1−xHfxN$\text{Al$_{1-x}$Hf$_{x}$N}$ Thin Films with Enhanced Piezoelectric Responses for GHz Surface Acoustic Wave Devices

open access: yesAdvanced Electronic Materials, EarlyView.
Reactively sputtered wurtzite Al1‐xHfxN thin films, exhibiting strong c‐axis texture and enhanced piezoelectric response, are demonstrated as a cost‐effective alternative to Al1‐xScxN. X‐ray absorption spectroscopy reveals that cross‐gap N 2p–Hf 5d hybridization increases the Born effective charge and enables a multifold increase in piezoelectric ...

Mechanochemical Defluorination of Polytetrafluoroethylene (PTFE) With Base Metals

open access: yesAngewandte Chemie, EarlyView.
Polytetrafluoroethylene (PTFE) mechanochemically reacts with safe‐to‐handle, abundant, and inexpensive base metals Zn and Al, as well as with metals like Cd and Pb, to produce sp2‐carbon and industrially important metal fluorides. The reactivity presents PTFE as a mechanochemical fluorination agent, with opportunities for closed‐loop reductive ...

Teor de fitato e proteína em grãos de feijão em função da aplicação de pó de basalto = Seed phytate and protein content in beans depending on the application of basalt powder

open access: yesActa Scientiarum. Agronomy, 2011
O teor de fitato nos grãos está correlacionado com o suprimento de fósforo à planta, porém não se sabe quanto este teor responde à disponibilidade mais lenta do nutriente no solo.

Highly Stabilized Ni‐Rich Cathodes Enabled by Artificially Reversing Naturally‐Formed Interface

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
The application of Ni‐rich cathode materials is obstructed by interfacial and structural instability. This work proposes a facile and cost‐effective Al‐based vapor‐phase surface reaction strategy on Ni‐rich cathode to maintain its structural integrity from near‐surface to bulk.
