Microenvironmental Reprogramming by 3D Anisotropic Cardiac Extracellular Matrix Induces Nuclear Remodeling and Epigenetic Maturation of Chemically Induced Cardiomyocytes

Advanced Functional Materials, EarlyView.
A 3D anisotropic hydrogel derived from heart extracellular matrix guides cytoskeletal alignment and nuclear remodeling in reprogrammed cardiomyocyte‐like cells. This study reveals how matrix alignment modulates nuclear envelope dynamics and chromatin state, triggering transcriptional and functional maturation.

Simulation of Pressure Pulsations

, 2020
Utmattelsesbelastning er den primære årsaken til turbinskade i vannkraftverk. Syklisk belastning fra trykkpulsasjoner kan forårsake slik utmattelsesbelastning. Tilegning av informasjon om trykkpulsasjoner, og samspillet mellom turbin og vannvei, kan bidra til å unngå tidlig svikt i turbinene. Fenomenet kan studeres gjennom feltmålinger, men å utføre og

Self‐Sintering Ionogel Binder for Flexible, Recyclable, and Healable Printed Giant Magnetoresistive Sensors

Advanced Functional Materials, EarlyView.
ABSTRACT Electronic waste has emerged as a major environmental challenge, driven by the massive consumption and a limited lifetime of modern electronic devices, stimulating the development of sustainable electronics. Here, an all‐biomaterial gelatin‐choline‐citric acid ([Ch][CA]) ionogel is developed as an active binder to realize self‐sintered ...

Experimental research of pulsation pressure and hydrodynamic noise at the bow of underwater vehicle

Xibei Gongye Daxue Xuebao
The design of the bow of the underwater vehicle affects its hydrodynamic performance, and a better design can reduce the direct impact of water on the bow and thus reduce the hydrodynamic noise of the underwater vehicle.

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

Advanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Experimental Investigation of the Characteristics of Discharge Pressure Pulsation in a Twin-Screw Refrigeration Compressor

Zhileng xuebao
To explore the characteristics of pressure pulsation in a twin-screw refrigeration compressor, transient pressures during the suction, compression, and discharge phases were measured, and the pressure pulsation characteristics were subsequently analyzed.

Development of a pulsation dampener for hydraulic systems of power plants

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2019
The article considers the development of a capacitance-type pressure pulsation dampener. The pressure pulsation dampener is used to reduce the noise of hydraulic systems which are subject to increased requirements for vibro-acoustic characteristics.

Spin Injection Of Exciton–Polaritons With Halide Perovskites At Room Temperature

Advanced Functional Materials, EarlyView.
A monolithic Tamm‐plasmon microcavity embedding a two‐dimensional halide perovskite enables room‐temperature spin injection of exciton‐polaritons under quasi‐resonant optical excitation. Polarization‐resolved spectroscopy reveals partial preservation of the injected spin in the lower polariton branch, while bare excitons remain fully depolarized.
