AI Article Synopsis
- The study analyzes local contact forces in granular crystals with face-centered cubic and hexagonal-close-packed structures when an external force is applied to a small area on the top surface.
- Differences in the crystal structures lead to distinct responses, which can be explained by examining how forces balance within their unique geometries.
- The presence of minor disorder in the crystals results in additional structural variations at both the top and bottom boundaries.
Article Abstract
We measure the local contact forces at both the top and bottom boundaries of three-dimensional face-centered-cubic and hexagonal-close-packed granular crystals in response to an external force applied to a small area at the top surface. Depending on the crystal structure, we find markedly different results which can be understood in terms of force balance considerations in the specific geometry of the crystal. Small amounts of disorder are found to create additional structure at both the top and bottom surfaces.

Glaucoma, a leading cause of blindness, demands innovative and effective treatments that surpass the limitations of current drug and surgical interventions to lower intraocular pressure. This study describes the generation of cell-repellent hydrogel patches, their deposition on the ocular surface, and a photoinduced chemical binding between the patches and the collagens of the eye. The hydrophilic and protein-repellent hydrogel patch is composed of a copolymer made from dimethylacrylamide and a comonomer unit with anthraquinone moieties.

Friction surfacing (FS) is a solid-state deposition process in which layers are deposited on a substrate surface by frictional heat and severe plastic deformation of a consumable stud material below its melting temperature. Bonding occurs due to accelerated diffusion. The deposition of several layers on top of each other is referred to as multi-layer FS (MLFS), a promising candidate for additive manufacturing (AM) as it offers advantages over fusion-based AM.

The steep temperature gradient near the bottom of the mantle is known to generate a negative correlation between the shear wave velocity ( ) and the depth in most regions of the D″ layer, as detected by seismological observations. However, increasing with depth is observed at the D″ layer beneath Central America, where the Farallon slab sinks, and the origin of this anomaly has not been well constrained. Here, we calculate the thermoelastic constants and obtain the elastic wave velocities of hydrous phase H with various Al contents and cation configurations, which may act as a water carrier to the D″ layer.

Traditional energy-integration X-ray imaging systems rely on total X-ray intensity for image contrast, ignoring energy-specific information. Recently developed multilayer stacked scintillators have enabled multispectral, large-area flat-panel X-ray imaging (FPXI), enhancing material discrimination capabilities. However, increased layering can lead to mutual excitation, which may affect the accurate discrimination of X-ray energy.

Continuous microenvironment modulation is an ongoing challenge in wound dressing, which includes excessive exudate absorption, oxygen delivery, bacterial inhibition and angiogenesis. Herein, we developed an construction strategy to fabricate a self-retaining double-layered wound dressing, where the top layer precursor was composed of Ca-containing polyvinyl butyral (PVB) solution dispersed with hydroxypropyl methylcellulose (HPMC) particles, and the bottom one consisted of sodium alginate (Alg) solution blended with Ag-doped mesoporous bioactive glass powders (Ag-MBG). When in use, both precursors were simultaneously squeezed out from the twin nozzles connected to the individual chambers of a twin-chambered syringe, whereby Ca in the top layer rapidly migrated downwards to crosslink Alg in the bottom layer, leading to the formation of an Alg/Ag-MBG (AA) functional hydrogel for filling an irregular wound.
