Advanced Functional Materials, EarlyView.Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale

Speedups of deterministic machines by synchronous parallel machines
Proceedings of the fifteenth annual ACM symposium on Theory of computing - STOC '83, 1983 The paper presents new speedups of deterministic multitape Turing machines by both fixed and variable structure parallel machines. Namely, it is shown that DTIME(T)\(\subseteq ATIME(T/\log T)\) and DTIME(T)\(\subseteq PRAM\)-time(\(\sqrt{T})\). These improve many previously known results.

Design and Synthesis of Peptide‐Polyester Conjugates for Cell‐Mediated Scaffold Degradation
Advanced Healthcare Materials, EarlyView.This work describes polycaprolactone (PCL)‐based biomaterials engineered to degrade in response to cell‐secreted proteases. A fast‐degrading peptide (Fast) sequence is integrated into a PCL conjugate backbone to produce a biomaterial that is selectively degraded by multiple cell types compared to its scrambled control (ScrFast).

Multipolar SPM machines for direct drive application: a comprehensive design approach [PDF]
, 2012 A closed-form, per-unit formulation is proposed, for the design of surface mounted permanent magnet motors with high number of poles. The model evaluates the shear stress, the power factor and the specific Joule loss as the indicators of the machine ...

Tree parsing with synchronous tree-adjoining grammars
, 2011 Restricting the input or the output of a grammar-induced translation to a given set of trees plays an important role in statistical machine translation. The problem for practical systems is to find a compact (and in particular, finite) representation of ...
