Hydrophobic MFI‐Type Zeolites via Alkali‐Cation‐Induced Defect Healing: Implications for Adsorbent and Catalyst Design

open access: yesAdvanced Materials, EarlyView.
Sub‐stoichiometric amounts of Na+ or K+ enhance defect healing during Silicalite‐1 (MFI) and TS‐1 calcination by promoting Si–O–Si annealing and healing framework vacancies. The resulting defect‐free zeolites are more hydrophobic and show improved butanol/water separation and improved activity and selectivity in the epoxidation of 1‐hexene, offering a ...

Sustainable Poly(Lactic Acid)/Graphene Oxide Bioelectronic Platform for Neurotransmitters Sensing and Tunable Stimulation of Astrocytes

open access: yesAdvanced Materials, EarlyView.
This work introduces sustainable PLA/graphene oxide bioelectronic interfaces featuring electrodes with tunable conductivity and strong electrocatalytic performance. These platforms were used to implement a new method for tuning astrocyte Ca2+ signaling and for the efficient detection of key biomarkers.

An Area/Performance Comparison of Subtractive and Multiplicative Divide/Square Root Implementations

open access: yes, 1995
The implementations of division and square root in the FPU's of current microprocessors are based on one of two categories of algorithms. Multiplicative techniques, exemplified by the Newton-Raphson method and Goldschmidt 's algorithm, share ...

Review of Inorganic Separator Engineering for Next‐Generation Lithium–Sulfur Batteries: Compromise or Cornerstone?

open access: yesAdvanced Materials, EarlyView.
Inorganic compound‐modified separators transform lithium–sulfur batteries from passive polysulfide confinement to active reaction‐pathway regulation. A Practical Relevance Index (PRI)‐guided framework bridges interfacial chemistry of inorganic separators with practical constraints, establishing unified design principles for scalable, high‐energy ...

Wearable Morphology‐Adaptive in‐Ear Device With Active Cleansing Capability for Multimodal Health Monitoring

open access: yesAdvanced Materials, EarlyView.
We present SCIENCE, an in‐ear multimodal physiological monitor featuring two key innovations. Water‐triggered morphological expansion (a 2‐mm cylinder to a 9‐mm spindle) achieves conformal adaptation across complex canal geometries. Simultaneously, active biofouling mitigation disrupts cerumen barriers, reducing sensor‐skin impedance by 20%.

Engineering Metal‐Pocket Cooperativity in Single‐Atom COF Nanozymes for Selective Cascade Catalysis

open access: yesAdvanced Materials, EarlyView.
A multilevel programming strategy is developed to engineer single‐atom COF nanozymes with tunable metal centers and chiral pockets inspired by heme–pocket cooperativity. This approach enables controlled metal–pocket interplay for asymmetric cascade catalysis, delivering high activity, selectivity, and recyclability in an asymmetric oxidation–aldol ...
