One‐Step Curcumin‐Mediated Multiphoton Lithography for Bioactive 3D Scaffolds
Advanced Functional Materials, EarlyView.Curcumin‐mediated multiphoton lithography enables one‐step fabrication of highly architected complex gelatin methacryloyl scaffolds by exploiting curcumin as a multifunctional bioactive photoinitiator. The resulting 3D structures support mesenchymal stem cell adhesion, proliferation, and migration, while exhibiting dual antibacterial activity through ...

Advanced Functional Materials, EarlyView.A meniscus‐guided microtransfer molding strategy enables scalable fabrication of grid‐type molecular martensite films with b‐axis‐correlated preferential texture. Sequential growth across microchannel intersections creates structurally continuous grids and robust thermoelastic actuation (∼11% strain, > 50 cycles, maximum force density: 7.1 × 109 N m−3).

SPIE Proceedings, 1989
This paper gives a summary of the current state of development of the King's College scanning x-ray microscope. The characteristics of the microscope and scanning stage are described, and preliminary work on the design of an environmental chamber for the examination of hydrated specimens and biological material is also reported.

High-Resolution Scanning X-ray Diffraction Microscopy
Science, 2008Coherent diffractive imaging (CDI) and scanning transmission x-ray microscopy (STXM) are two popular microscopy techniques that have evolved quite independently. CDI promises to reach resolutions below 10 nanometers, but the reconstruction procedures put stringent requirements on data quality and sample preparation.

Scanning X-Ray Emission Microscopy
Applied Physics Letters, 1972This letter describes the production of continuous tone micrographs from the x radiation emitted by a specimen subjected to electron bombardment in a scanning electron microscope. The x rays are collected and energy analyzed with an energy-dispersive spectrometer so that topographically rough specimens may be examined.

Scanning Microscopy with Soft X Rays
Proceedings, annual meeting, Electron Microscopy Society of America, 1985Among the various forms of soft x-ray microscopy, scanning offers several advantages. It is capable of forming images with the lowest radiation dosage to the specimen. The image is recorded digitally, therefore quantitative information on specimen absorptivity as a function of position is immediately available.

Scanning Soft X-Ray Microscopy
SPIE Proceedings, 1988Soft x-ray microscopy allows high resolution imaging of wet biological samples. 100A resolution has been demonstrated with contact microscopy while to date scanning microscopes have achieved 750A resolution. The present state of soft x-ray microscopy is reviewed with emphasis on scanning systems.

Microscopy using soft X rays has considerable potential for examining a variety of specimens at a higher resolution than is possible with visible light. This is because the wavelengths of soft X rays (1−10 nm) are about two orders of magnitude shorter than visible wavelengths. The predominant contrast mechanism in x-ray microscopy is one of absorption,
