Advanced Functional Materials, EarlyView.This work presents a novel sensing platform using metallo‐dielectric cryosoret nano‐assemblies and lossless photonic crystals to overcome limitations of conventional plasmonic biosensors. The hybrid system enhances both electric and magnetic field interactions, enabling amplified fluorescence, ultralow detection limits, and prism‐free, objective‐free ...

Advanced Functional Materials, EarlyView.This study examines how pore shape and manufacturing‐induced deviations affect the mechanical properties of 3D‐printed lattice materials with constant porosity. Combining µ‐CT analysis, FEM, and compression testing, the authors show that structural imperfections reduce stiffness and strength, while bulk material inhomogeneities probably enhance ...

Accurate pointing of tungsten welding electrodes [PDF]
, 1971 Thoriated-tungsten is pointed accurately and quickly by using sodium nitrite. Point produced is smooth and no effort is necessary to hold the tungsten rod concentric. The chemically produced point can be used several times longer than ground points. This

Advanced Functional Materials, EarlyView.Buckling‐resistant and trace‐stacked (BRATS) intracortical microelectrode arrays (MEAs) eliminate the need for insertion aid and complex surgical setup, resulting in minimal inflammatory tissue response, compared to conventional flexible MEAs inserted with aid. Trace stacking effectively doubled the channel count without increasing the MEA shank width,

Light-induced olefin metathesis
Beilstein Journal of Organic Chemistry, 2010 Light activation is a most desirable property for catalysis control. Among the many catalytic processes that may be activated by light, olefin metathesis stands out as both academically motivating and practically useful.

Epitaxial Interface‐Driven Photoresponse Enhancement in Monolayer WS2–MoS2 Lateral Heterostructures
Advanced Functional Materials, EarlyView.Surface potential distribution image, along with the derived electric field distribution across the interface, reveals that the electric field reaches its peak at the interface. Additionally, the spectral response of the heterointerface exhibits higher and broader features compared to its bare counterparts.
