Modification of the SHABERTH bearing code to incorporate RP-1 and a discussion of the traction model [PDF]

Recently developed traction data for Rocket Propellant 1 (RP-1), a hydrocarbon fuel of the kerosene family, was used to develop the parameters needed by the bearing code SHABERTH in order to include RP-1 as a lubricant choice. The procedure for inputting

Stress‐Induced Melting Controlled Failure Mechanisms of Methane Hydrate

Advanced Science, EarlyView.
We study methane hydrate via nanoindentation and nuclear magnetic resonance (NMR), finding its regional melting and mechanical properties, challenging existing views on hydrogen‐bonded crystals. Abstract Methane hydrate, a kind of nonstoichiometric crystalline, attracted worldwide attentions as a promising substitute energy. Its Dissociation is thought

Cytokine‐Engineered Chimeric Antigen Receptor‐T Cell Therapy: How to Balance the Efficacy and Toxicity

Advanced Science, EarlyView.
Cytokine‐engineered CAR‐T cells represent a promising immunotherapy against malignancies due to direct tumor killing and potent immunity response. However, significant toxicities, including CRS and ICANS, have restricted clinical applications. How to keep the risk‐benefit balance of the advanced therapy is of great importance for maximizing the benefit

Liver Stiffness Rises Early in MASLD and Drives Inflammation, Lipid Dysmetabolism, and Fibrosis via Piezo1–YAP Mechanotransduction

Advanced Science, EarlyView.
Progressive stiffening of the hepatic extracellular matrix and free fatty acid overload activate the mechanosensor Piezo1 in steatotic hepatocytes, inducing calcium influx and nuclear translocation of Yes‐associated protein. YAP‐dependent nuclear signaling further drives inflammatory and fibrotic gene programs, lipid metabolic reprogramming, and ...

Beyond Transconductance: Cell‐Polymer Coupling Determines Fidelity in Action Potential Recording via Electrolyte‐Gated Polymer Transistors

Advanced Science, EarlyView.
High electrical performance alone does not guarantee efficient bioelectronic signal transduction. Despite excellent mixed ionic‐electronic conduction, recordings from cardiomyocytes reveal that p(g2T‐TT)‐based OECTs predominantly transduce field potential FP‐like signals due to weak cell‐polymer coupling.

Engineered Interpenetrating MXene Networks in Aramid Layered Films for Antioxidant and Broadband Electromagnetic Interference Shielding

Advanced Science, EarlyView.
This study introduces an innovative interpenetrating layered structure, comprising alternating aramid nanofiber (ANF) layers and MXene layers, fabricated through a directional freeze–thaw intercalation–gel‐film formation strategy. Unlike traditional homogeneous layered films, this unique layered structure features mutually embedded conductive and ...
