Zwitterionic Self‐Assembled Monolayer for Simultaneous Noise Suppression and Hole Extraction in High‐Performance Near‐Infrared Organic Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a new hole transporting material (HTM) mechanism for self‐assembled monolayers in near‐infrared organic photodetectors. The formation of zwitterions induces a strong electric field that significantly increases the work function of HTM‐coated indium tin oxide substrates. The devices exhibit low dark current and noise, along with high

Controlling 3D Contractility via Engineered Fibrous Hydrogel Composites

open access: yesAdvanced Functional Materials, EarlyView.
A tunable composite contractile assembly (CCA) is developed that can permit or resist contraction without changing cell‐adhesion and density, unlike collagen whose inherent coupling of these ECM cues limits its use as a platform in contractility studies.

Estimation of transitory changes in bending stiffness using the Hilbert-Huang transform [PDF]

open access: possibleBridge Structures, 2019
A finite element model of a bridge can be calibrated based on field measurements, and then updated periodically using a structural health monitoring system. The value of a structural parameter such as bending stiffness can be adjusted to measurements using well-known modal updating techniques and monitored in conjunction with external effects such as ...

Internai Friction Transitory Effects Associated with Martensitic Transformation in Ni-Ti Alloys

Physica Status Solidi (a), 1988
Low-frequency (≈ 1 Hz) internal friction associated with the martensitic transformation in NiTi, is systematically investigated under diverse heating and cooling rates T. The main contribution to the internal friction is due to transistory phenomena which decrease to zero with T.

Indium Telluride (II′): Transitory Intermediate Phase in the Transformation InTe(II) to InTe(I)

Science, 1965
The high-pressure cubic metallic form of indium telluride, InTe(II), transforms at 1 atmosphere to a new transitory polymorph, designated InTe(II′), which, in turn, transforms to the stable tetragonal polymorph InTe(I). The new polymorph is apparently tetragonal with unit-cell dimensions a 0 = 6.06 Å,
