Article Abstract
Well-ordered tilted silicon nanobelt arrays have been fabricated over a large area (≥2.5 cm(2)) by metal assisted chemical etching of pre-patterned silicon, which demonstrated markedly enhanced solar hydrogen evolution performance, compared with planar silicon of the same type and previously reported silicon nanowires prepared in a similar way.

Subwavelength gratings serve as a pivotal tool in optical devices, enabling the flexible modulation of the effective refractive index of waveguide modes and modulating the guided mode through intense optical scattering at subwavelength intervals. Nevertheless, the modulation space remains limited. Incorporating phase change materials (PCMs) can achieve significantly higher modulation efficiency.

The metalens comprises an array of SiN nanopillars. We manufactured the metalens using 193 nm deep-ultraviolet scanner lithography, suitable for high-volume manufacturing.

Three major contributions of the proposed antenna design are: (i) a rounded wave is obtained by stimulating the silicon ceramic via a fan blade formed slot; (ii) a mirror orientation of aperture and suspension of partially reflecting surface (PRS) helps to get better isolation with an S-component and far-field component, respectively; and (iii) the random forest and XGBoost technique predicts the | | of the designed aerial effectively. A coating of graphene over silicon dielectric makes the radiator tunable.

We demonstrate electronic sensing of DNA nanostar (NS) condensate. Specifically, we use electrokinetic nanofluidics to observe and interpret how temperature-induced NS condensation affects nanochannel current. The increase in current upon filling a nanochannel with NS condensate indicates that its electrophoretic mobility is about half that of a single NS and its effective ionic strength is ∼35% greater than that of 150 mM NaCl in phosphate buffer.

The core indexing engine of the electron Channelling ORientation Determination (eCHORD) technique has been modified to significantly minimize indexation errors in the resulting orientation maps, thus enhancing accurate microstructure characterization. Orientation mapping using eCHORD involves acquiring a sequence of backscattered electron images by rotating the region of interest (ROI) within the scanning electron microscope, the sample being tilted in the range ∼10°-15°. Such an image series forms a data-cube from which intensity profiles can be extracted at each position in the ROI, reflecting the variation of the backscattered electron signal as a function of sample rotation.
