X‐Ray Computed Tomography Quantifies Primary Phases and Reveals Crack Morphology in High‐Cycle Fatigue of Aluminum Alloy EN AW‐2618A

open access: yesAdvanced Engineering Materials, EarlyView.
Primary phases and a fatigue crack are studied in a forged blank of an aluminum alloy using synchrotron and laboratory X‐ray computed tomography. To image the crack, the fatigue test is interrupted, and a static tensile load is applied to open the crack.

"Todo" em contextos coletivos e distributivos The brazilian portuguese quantifier "Todo" in distributive and in collective contexts

open access: yesDELTA: Documentação de Estudos em Lingüística Teórica e Aplicada, 2007
"Todo" pode tomar um NP (nome nu) ou uma descrição definida (DP) plural ou singular como argumento nominal. Esse quantificador opera sobre partes de sua restrição e de seu escopo nuclear e relaciona um ao outro.

The Nonlinear Visco‐Hyperelastic Damage Mechanics of Individual Electrospun Polycaprolactone Fibers: Experiments and Modeling

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates the complex mechanics of individual electrospun polycaprolactone fibers under small and large strains. Combining experiments with a visco‐hyperelastic damage model, this work reveals and quantifies these fibers’ nonlinear behavior, including strain‐stiffening, viscoelasticity, and damage.

Sol–Gel Synthesis of Ca2.5Ag0.3Sm0.2Co4O9 Semiconducting Materials for Thermoelectric Applications in Aerospace Systems

open access: yesAdvanced Engineering Materials, EarlyView.
Ca2.5Ag0.3Sm0.2Co4O9 semiconductor materials are synthesized and produced in this study using the sol–gel and cold pressing techniques for thermoelectric generator applications. As template samples are added, the Seebeck coefficient and power factor values rise, peaking at 800 °C for Ca2.5Ag0.3Sm0.2Co4O9 at 274.47 μV K−1 and 0.58 mW mK−2, respectively.

Removing Homocoupling Defects in Alkoxy/Alkyl‐PBTTT Enhances Polymer:Fullerene Co‐Crystal Formation and Stability

open access: yesAdvanced Functional Materials, EarlyView.
PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

Joule‐Assisted Nanotherapeutic Urethral Stent (JANUS) for Spatiotemporal Theragenerative Treatment of Urethral Strictures

open access: yesAdvanced Functional Materials, EarlyView.
Joule‐assisted nanotherapeutic urethral stent harnesses a smart, biodegradable magnesium stent to orchestrate spatiotemporal theragenerative therapy for urethral strictures. Magnetically induced Joule heating enables on‐demand drug release and bacterial ablation, while simultaneously guiding urothelial regeneration.

Particle verbs and the conditions of projection [PDF]

open access: yes, 2003
In this paper I discuss the properties of particle verbs in light of a proposal about syntactic projection. In section 2 I suggest that projection involves functional structure in two important ways: (i) only functional phrases can be complements, and ...
