High Throughput Aerosol Jet Printing to Operationalize High Aspect Ratio Patterning

Advanced Materials Technologies, EarlyView.
High‐throughput aerosol jet printing poses distinct limiting mechanisms to the printing process. These include rapidly changing ink chemistries, atomization instabilities, and liquid‐phase spreading. The combination of in‐line heating, process monitoring, and traditional optimization procedures enables rapid printing of high‐aspect‐ratio structures ...

Programmable Variable‐Stiffness Multilayer Elastomer Composites With High‐Aspect‐Ratio Low‐Melting‐Point Alloy Inclusions

Advanced Materials Technologies, EarlyView.
High‐aspect‐ratio low‐melting‐point alloy inclusions are embedded within multilayer silicone laminates to create thermally programmable stiffness. Sequential activation of alloy‐rich layers produces four distinct mechanical states and reconfigures tendon‐driven actuator trajectories under the same load.

On the spectral properties of grid operators for FEM schemes in elasticity theory. Two-dimensional schemes

Учёные записки Казанского университета: Серия Физико-математические науки
The spectra of grid operators in some finite element method (FEM) schemes for solving twodimensional problems of elasticity theory were investigated. It was revealed that, for a number of classical FEM schemes, a mutual influence between the spectra of ...

Silk Fibroin Nanofiber–Immobilized Horseradish Peroxidase Enables Continuous Preparation of Injectable Hydrogels With Negligible Residual Enzyme for Drug Delivery

Advanced Materials Technologies, EarlyView.
Overcoming the immunogenicity challenges of enzyme‐mediated crosslinking, a flow‐through reactor utilizing SFNF‐HRP enables the continuous production of injectable hydrogels. This continuous platform ensures homogeneous crosslinking while minimizing residual HRP in the resulting hydrogels.

Assessment of the volumetric accuracy of a machine with geometric compensation

, 2001
Volumetric assessment of Cartesian machines using a universal three-axis rigid body error model was presented. Application of volumetric correction using the same model has allowed machines to produce parts to tighter tolerances. A method for calculating

Region‐Specific Profiling of the Gut Microbiome and Metabolite Landscape in Response to Dietary Intervention Using Electronics‐Free Ingestible Smart Sampling Capsules

Advanced Materials Technologies, EarlyView.
Region‐specific profiling of the gut microbiome is achieved non‐invasively using electronics‐free ingestible sampling capsules that activate at defined intestinal sites through stimuli‐responsive coatings. Deployed in a porcine dietary intervention model, the capsules resolve spatially distinct, fiber‐driven shifts in microbial composition and short ...

Volumetric estimation of landslide-induced terrain change using conditional GAN with multi-temporal DEMs and satellite imagery

International Journal of Applied Earth Observations and Geoinformation
Estimating landslide volumes remains challenging because of the limited availability of high-resolution terrain data. Traditional methods often rely on empirical area-to-volume conversion formulas, which introduce significant uncertainties due to terrain

Zero‐Waste Manufacturing of Ophthalmic Lenses by Direct Fluidic Shaping in Arbitrary Domains

Advanced Materials Technologies, EarlyView.
Conventional ophthalmic lens manufacturing discards up to 97% of material through subtractive processes. The Cookie Cutter algorithm extends Fluidic Shaping to arbitrary rim geometries. The framework prescribes a spatially varying boundary height that, under neutral buoyancy and surface tension, shapes curable polymer into spherocylindrical lenses that
