Highly Conductive and Transparent Coatings via Low‐Temperature Hydroiodic Acid Vapor Treatment of Oxo‐Graphene Thin Films

open access: yesAdvanced Materials Technologies, EarlyView.
The double self‐assembly (DSA) method applied to oxo‐graphene (oxo‐G) flakes followed by hydroiodic acid (HI) vapor treatment and low‐temperature annealing yields highly conductive, optically transparent thin films with the potential for applications in electronic and optoelectronic devices.

Trans-Medium Craft and Earth's Plasma Architecture: Field-Aligned Corridors in the Ionosphere

open access: yes
Earth’s atmosphere and near-space environment are not empty. They form a continuously structured plasma medium shaped by electromagnetic, gravitational, and solar inputs. This medium self-organizes into filaments, sheets, ducts, knots, and cavities that guide energy, particles, and waves over vast distances.

[Trans-Texas Airways passengers standing planeside]

open access: yes, 1955
Photograph of a group of sixteen men and two women who are Trans-Texas Airways passengers standing planeside. The men wear hats but carry their coats slung over their arms. The sky is cloudy, but all are smiling.

3D‐Printed Actuator Powered by Liquid Crystal Elastomer Muscles at the Water–Air Interface

open access: yesAdvanced Materials Technologies, EarlyView.
Soft robots for unstructured environments require responsive, durable actuators. Liquid crystal elastomers (LCEs) provide large reversible deformations under thermal or optical stimuli. Direct ink writing enables fabrication of LCE actuators integrated with silicone, with mesogen chemistry and oligomers optimized for printable inks.

Pointlike Material Accumulation and Displacement in Azopolymer Thin Films Driven by Spatial Light Modulation

open access: yesAdvanced Optical Materials, EarlyView.
A maskless, SLM‐driven approach enables the deterministic inscription of arbitrary topographical features in azopolymer films by mapping complex vectorial light fields onto local viscoplastic stress. This platform allows for the rapid generation and dynamic erasure of high‐aspect‐ratio micro‐spikes, offering a versatile tool for reconfigurable flat ...

A fully echo-guided trans-apical aortic valve implantation [PDF]

open access: yes, 2017
The trans-apical aortic valve implantation (TA-AVI) is an established technique for high-risk patients requiring aortic valve replacement. Traditionally, preoperative (computed tomography (CT) scan, coronary angiogram) and intra-operative imaging ...

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation

open access: yesAdvanced Optical Materials, EarlyView.
A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.
