Programming Structural Symmetry and Emission in Low‐Dimensional Hybrid Perovskites via Time and Temperature

open access: yesAdvanced Science, EarlyView.
We demonstrate programmable structural symmetry and emission in benzylammonium‐based low‐dimensional hybrid perovskites. Continuous shaking transforms orthorhombic platelets into a lower‐symmetry monoclinic phase with broadband emission, whereas thermal activation drives the reverse pathways toward a higher‐symmetry configuration resembling the ...

The Application of Fusing Inner-cutting Technology on Coiled Tubing Stick Releasing

open access: yesShiyou jixie, 2016
The common solution for coiled tubing downhole sticking is vigorous pulling,and fishing per section after breaking off.But the operation could easily lead to coiled tubing scrap,and the operation process is complicated and time-consumed.To address the ...

Targeting the KCNC3‐Dependent Anterior Insular‐Lateral Orbitofrontal Cortex Glutamatergic Circuit Attenuates Post‐Traumatic Anxiety

open access: yesAdvanced Science, EarlyView.
Frontal lobe traumatic brain injury is associated with hyperactivity of an insular–orbitofrontal circuit in both patients and mice. By combination of integrating functional imaging, cell‐type–specific circuit manipulation, single‐cell transcriptomics, and whole‐cell recordings, this work identifies the downregulation of the potassium channel KCNC3 in ...

TECHNOLOGY OF DEVELOPMENT OF WELLS USING COILED TUBING INSTALLATIONS [PDF]

open access: yes
The basis of coiled tubing technologies is the use of a flexible metal pipe, which is wound on a drum and lowered and raised from the well by a special unit (Fig. 1: a, b). The mobility of coiled tubing installations makes it possible to effectively use

Influence of Coiled Tubing Size and Lowering Depth on Velocity String Operation

open access: yesShiyou jixie, 2020
Aiming to resolve the problem of liquid loading at the well bottom during gas well production and increase the well production by installing coiled tubing as a velocity string, a study on the influence of coiled tubing size and lowering depth on velocity

Combining Elastic and Plastic Fatigue Damage in Coiled Tubing

open access: yes, 2011
Coiled tubing is a continuous pipe that, having been coiled around a reel for storage, can be deployed and used as a pipeline or riser. During deployment as a riser, the coiled tubing is unspooled from the reel, run into the water and connected to the ...

Stochastic Entanglement of Deterministic Origami Tentacles For Robust Robotic Grasping

open access: yesAdvanced Science, EarlyView.
This study introduces an origami tentacle gripper to robustly grasp objects‐in air, underwater, and even in orbital space‐by exploiting a synergy between local, deterministic deformation programming and global, stochastic entanglements. A single origami tentacle can be designed to coil with a simple tendon pull.

Physics‐Aware Machine‐Learning‐Driven Inverse Design of Broadband Ultra‐Open Acoustic Metamaterials

open access: yesAdvanced Science, EarlyView.
A physics‐aware machine‐learning framework enables inverse design of ultra‐open acoustic silencers by decoupling spectral and radial design spaces. The approach rapidly identifies broadband, compact, and highly ventilated architectures, while revealing hidden linear design rules that link geometry, impedance matching, and acoustic performance.
