We have revealed the fundamental embryonic structure of deformation twins using in situ mechanical testing magnesium single crystals a transmission electron microscope. This consists an array twin-related laths on scale several nanometers. A computational model demonstrates that this should be generic feature at incipient stage twinning when there are correlated nucleation events. Our results shed light origin twinning-induced plasticity and transformation toughening, critical to development...
Abstract Strengthening materials via conventional “top-down” processes generally involves restricting dislocation movement by precipitation or grain refinement, which invariably restricts the of dislocations away from, towards, a crack tip, thereby severely compromising their fracture resistance. In present study, high-entropy alloy Al 0.5 CrCoFeNi is produced laser powder-bed fusion process, “bottom-up” additive manufacturing process similar to how nature builds structures, with...
Ancient Jian wares are famous for their lustrous black glaze that exhibits unique colored patterns. Some striking examples include the brownish "Hare's Fur" (HF) strips and silvery "Oil Spot" (OS) Herein, we investigated surface of HF OS samples using a variety characterization methods. Contrary to commonly accepted theory, identified presence ε-Fe2O3, rare metastable polymorph Fe2O3 with magnetic properties, in both samples. We found crystals up several micrometers size exclusively made...
A new facility for microdiffraction strain measurements and microfluorescence mapping has been built on beamline 12.3.2 at the advanced light source of Lawrence Berkeley National Laboratory. This benefits from hard x-radiation generated by a 6 T superconducting bending magnet (superbend). provides x-ray spectrum 5 to 22 keV flux within 1 μm spot ∼5×109 photons/s (0.1% bandwidth 8 keV). The radiation is relayed superbend focus in experimental hutch toroidal mirror. tailored two pairs...
A novel freeze casting technique was employed to obtain 3D porous LLZO solid-electrolyte scaffolds that were infiltrated with NMC-622 cathode material form thick composite electrodes for all-solid-state batteries.
Abstract The application of solid‐state electrolytes in Li batteries is hampered by the occurrence Li‐dendrite‐caused short circuits. To avoid cell failure, can only be stressed with rather low current densities, severely restricting their performance. As grain size and pore distributions significantly affect dendrite growth ceramic such as 7 La 3 Zr 2 O 12 its variants; here, a “detour buffer” strategy to bring superiority both coarse fine grains into play, proposed. validate mechanism,...
Abstract The repair of damaged Ni‐based superalloy single‐crystal turbine blades has been a long‐standing challenge. Additive manufacturing by an electron beam is promising to this end, but there formidable obstacle: either the residual stress and γ/γ ′ microstructure in single‐crystalline fusion zone after e‐beam melting are unacceptable (e.g., prone cracking), or, solutionizing heat treatment, recrystallization occurs, bringing forth new grains that degrade high‐temperature creep...
Dislocation recovery lowering the driving force for recrystallization would be able to suppress latter in Ni-based superalloy single crystals, but was believed unlikely due their low stacking-fault energy. Defying this traditional wisdom, here we show that efficient can realized once γ′-precipitates start dissolve. Our microscopy evidence tracking distribution/configuration of dislocations reveals shifting γ/γ′ interphase boundaries release trapped there, facilitating annihilation and...
Flexoelectric effects hold promising applications in sensing, actuating, and energy capturing, thus it is demanded to measure the flexoelectric coefficient tensors of dielectric materials accurately. In this work, an approach measuring effective tensor component μ 2312 polymeric developed by imposing a torque load upon half cylindrical specimen. It proven that can be calculated assessing electric charge on axial plane strain gradient along radial direction, both induced torque. To overcome...
Abstract Smart contact lens has drawn extensive research interests due to the noninvasive real-time detection of human body provide biomedical information for health management. However, it been difficult accurately measure physiological signals in tears, and use external power source also hindered future applications. Here, we demonstrated an organic electrochemical transistor based multiplexed sensors self-powered by solar cells (OSCs). The integrated device was fabricated via simple...
The Visible and Near-Infrared Imaging Spectrometer (VNIS), using two acousto-optic tunable filters as dispersive components, consists of a VIS/NIR imaging spectrometer (0.45–0.95 μm), shortwave IR (0.9–2.4 μm) calibration unit with dust-proofing functionality. VNIS was utilized to detect the spectrum lunar surface achieve in-orbit calibration, which satisfied requirements for scientific detection. Mounted at front Yutu rover, objects that are detected 45° visual angle obtain spectra...
Drug sensitivity is essential for identifying effective treatments. Meanwhile, circular RNA (circRNA) has potential in disease research and therapy. Uncovering the associations between circRNAs cellular drug crucial understanding response resistance mechanisms. In this study, we proposed DeepHeteroCDA, a novel circRNA-drug association prediction method based on multi-scale heterogeneous network graph attention mechanism.
