Visualizing and Quantifying Impact with Mechanochromic Sensing Paints Based on Self‐Assembled Polydiacetylene‐Silk Core‐Shell Vesicles

Advanced Science, EarlyView.
Tracking physical impacts is important in many fields. Self‐assembled microparticles made from polydiacetylene and silk fibroin that change color from blue to red when hit can provide an alternative approach to traditional mechanical transducers, quantitatively visualizing impact with responses ranging from <100 to 770 N.

Naval Engineering. A National Naval Obligation [PDF]

, 2000
Abstract : Since its creation by Congress over fifty years ago, the Office of Naval Research (ONR) has been charged with the national responsibility of maintaining a vigorous Science and Technology program in areas that are of critical importance to the maintenance of US naval superiority. ONR accomplishes this mission through research, recruitment and

Multi‐Scale Structural Effects of External Electrical Fields of Melt Tracks in Laser Powder Bed Fusion

Advanced Science, EarlyView.
Laser material processing is a promising technique for fabricating metal structures. Here, external electric field (EFs) assisted laser processing of metallic powders are investigated. EFs affect the melt tracks through changes in their stability and influence the grain structure in conjunction with laser intensity distribution methods. The EF‐assisted

Targeted H2S Delivery System Attenuates Blood‐Spinal Cord Barrier Disruption after Spinal Cord Injury by Reshaping the Ferritinophagy Pathway

Advanced Science, EarlyView.
The αvβ3‐mediated SPRC@MPDA‐RGD targets broken endothelial cells and controllably releases SPRC. CSE is then activated to produce endogenous H2S, which inhibits ferritinophagy. In brief, H2S inhibits autophagy by activating the PI3K/Akt/mTOR pathway, thereby suppressing the ferroptosis process mediated by NCOA4, and ultimately promoting the ...

Targeted Mitochondrial ECSIT Overexpression Attenuates MASH by Increasing OTUD3 Expression

Advanced Science, EarlyView.
Mitochondrial ECSIT expression is reduced during MASH pathogenesis. Overexpression of mitochondrial ECSIT mitigates steatohepatitis and maintains hepatic metabolic homeostasis. Mechanistically, ECSIT enhances intramitochondrial OTUD3 expression to stabilize SIRT3 through deubiquitination, thus preserving mitochondrial function and impeding disease ...

Large Anomalous Hall Effect, Non‐Vanishing Berry Curvature in (110) FeRh Antiferromagnet Films via Interface Strain

Advanced Science, EarlyView.
This study demonstrates a strain‐tunable anomalous Hall response in the (110)‐oriented FeRh thin film. First‐principles calculations reveal that strain‐induced symmetry lowering redistributes Berry curvature near the Fermi level via band shifts and avoided crossings.

Dynamic simulation on multilevel coupled vibration of a naval gun under foundation motion excitation of ship

Alexandria Engineering Journal
To study the multilevel coupled vibration of a naval gun under the foundation motion excitation of the ship, a mechanical-electrical-hydraulic coupled dynamic model of the naval gun including the follow-up systems’ influence was established.

TRAP5 Inhibition Targeting Scar‐Associated Macrophages Ameliorates Acute Kidney Injury to Chronic Kidney Disease Transition

Advanced Science, EarlyView.
This study delineates macrophage heterogeneity along the acute kidney injury to chronic kidney disease transition. Single‐cell RNA sequencing reveals a TRAP5+ scar‐associated macrophage subset driven by Spp1–Cd44 signaling and mitochondrial metabolic reprogramming.
