Controlling charge injection in organic field-effect transistors using self-assembled monolayers [PDF]

open access: yes, 2006
We have studied charge injection across the metal/organic semiconductor interface in bottom-contact poly(3-hexylthiophene) (P3HT) field-effect transistors, with Au source and drain electrodes modified by self-assembled monolayers (SAMs) prior to active ...

CO 2 Fluxes and Soil Responses to Straw and Herbicide in Peanut

open access: yesLand Degradation &Development, Volume 37, Issue 7, Page 2927-2944, 30 April 2026.
ABSTRACT Peanut cultivation plays an important agronomic role in Brazil, especially in rotation with sugarcane, promoting biological nitrogen fixation and improving soil quality. This study aimed to test the hypothesis that the combined use of sugarcane mulch, peanut cultivation, and herbicide application would affect soil CO₂ fluxes, soil chemical ...

Generating Cell Surface Nucleated Hydrogels with an Artificial Membrane‐Binding Transglutaminase

open access: yesAdvanced Functional Materials, Volume 36, Issue 27, 2 April 2026.
Cell‐based therapies require advanced strategies to enhance cell delivery and bioactivity. Cell membrane engineering offers an avenue to impart new functions to delivered cells to boost their viability and function. Here, an artificial membrane‐binding transglutaminase is generated and biophysically characterized.

Local charge transfer doping in suspended graphene nanojunctions

open access: yes, 2012
We report electronic transport measurements in nanoscale graphene transistors with gold and platinum electrodes whose channel lengths are shorter than 100 nm, and compare them with transistors with channel lengths from 1 \textmu{}m to 50 \textmu{}m.

Comparação entre dois métodos de determinação de cálcio ionizável em amostras de recém-nascidos [PDF]

open access: yes, 2013
Changes in ionized calcium (iCa) concentration seem to occur in newborns when the calcium supply from the mother is disconnected at birth, and a related hypocalcemia is produced. Thus, measurement of iCa is of particular importance in newborns.
