Advanced Materials, EarlyView.This study demonstrates a self‐assembly process to generate free‐standing piezoelectric nanomembranes, forming ultracompact microtubular acoustic wave sensors and actuators. The miniaturized 3D piezoelectric platform reported in this work can be applied in telecommunication, energy harvesting, and acoustofluidics. Moreover, the 3D self‐assembly can add

In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts
Advanced Materials, EarlyView.An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.

The conceptual question among sovereignty, biopolitics and law: a sensible point between Foucault and Agamben [PDF]
, 2012 The concept of biopolitics has its origin on the Michel Foucault works developped since 1975 to 1979. In this period, the author introduced the foundations for a new approach about the modern government, based in both crescent enpowerment on individuals ...

Naturalness and theoretical constraints on the Higgs boson mass
, 2013 Arbitrary regularization dependent parameters in Quantum Field Theory are usually fixed on symmetry or phenomenology grounds. We verify that the quadratically divergent behavior responsible for the lack of naturalness in the Standard Model (SM) is ...

Multiphysics‐Driven Assembly of Biomimetic Vesicles
Advanced Materials, EarlyView.Artificial extracellular vesicles, derived from cell membranes, are manufactured using a multiphysics‐integrated microfluidic platform that combines nanoknife membrane rupture, herringbone chaotic mixing, and acoustothermal modulation. This standardizable workflow enables the predictable control of vesicle formation and therapeutic loading, while ...

Toward a Consensus Characterization Protocol for Organic Thermoelectrics
Advanced Materials, EarlyView.We advocate a common consensus on accurate and standardized reporting of performance metrics in the field of organic thermoelectrics. We summarize prevalent issues in the literature and propose a pre‐submission checklist to support the publication of reproducible results.

Advanced Materials Interfaces, EarlyView.Surface roughness and chemistry of novolak‐based grayscale resists are dependent on both exposure dose and post‐exposure thermal treatment. The observed trends align with the viscoelastic phase separation model and underscore the need to consider both thermodynamic and kinetic factors in resist processing. By tailoring thermal treatment, it is possible

Substituent Effects on Cyanine Dyes Vary with Position and Chain Length
Advanced Optical Materials, EarlyView.In cyanines, substituent effects vary as a function of substituent position and cyanine length. Electron‐donating‐ and ‐withdrawing groups at meso‐ and α‐positions of 4n+1/4n−1 long cyanines (n = 1, 2, 3…) cause opposing, hypsochromic and bathochromic shifts of the 1st UV–vis absorption bands.
