Decoupling Photochemical and Photothermal Effects Using Molecular Motors Enables Fast, Intelligent, and Life‐Like Motions in Soft Materials

open access: yesAdvanced Materials, EarlyView.
A light‐responsive liquid crystal (LC) polymer network integrating molecular rotary motors and photothermal converters enables the decoupling of photochemical and photothermal effects. Selective wavelength activation allows orthogonal control over persistent shape encoding and fast reversible motion, enabling programmable soft robots capable of complex

Matrix characterizations of circular-arc graphs [PDF]

open access: yesPacific Journal of Mathematics, 1971
Abstract : A graph G is a circular-arc graph if there is a 1-1 correspondence between the vertices of G and a family of arcs on a circle such that two distinct vertices are adjacent when the corresponding arcs intersect. Circular-arc graphs are characterized in terms of their adjacency matrix. (Author)

Fabrication of TiN/TiO2 Nanotube‐Based Heterostructure for Hydrogen Sensing Applications

open access: yesAdvanced Materials Interfaces, EarlyView.
A hydrogen sensor based on titanium dioxide nanotubes coated with titanium nitride has been developed. The coating process causes a mixed titanium oxynitride layer to form, which improves the sensor performance. Sensor response R depends on the TiN thickness and is not degraded after 7 days in air.

Modeling of Reverse Curves on a Railway Line Using the Analytical Design Method

open access: yesDesigns
This study discusses the issue of designing reverse curves, i.e. a geometric system consisting of two circular arcs (usually with different radii), directed in opposite directions and directly connected to each other.

An Integrated NLP‐ML Framework for Property Prediction and Design of Steels

open access: yesAdvanced Science, EarlyView.
This study presents a data‐driven framework that uses language‐processing techniques to interpret steel processing descriptions and machine‐learning models to predict mechanical properties. By organising complex process histories into meaningful groups and enabling rapid property forecasts, the work supports faster, more informed steel design through ...

Tunable Negative Thermal Expansion in Fe/Cr‐Substituted Nd2Co17 Compounds via Magnetoelastic Coupling

open access: yesAdvanced Science, EarlyView.
This study achieves anisotropic thermal expansion tuning in Nd2(Co1‐xFex)17‐yCry compounds via a magnetoelastic strategy. Variable‐temperature synchrotron X‐ray diffraction reveals that increased Fe content induces switchable lattice responses. Compositional control reduces the volume expansion coefficient αV by 20% (x═0.7) and modulates TC (442–625 K),

Side Chain Elimination Enables Low‐Cost Fused‐Ring Acceptors and Reveals a Compact Tetrameric Structure for High‐Photocurrent Organic Solar Cells

open access: yesAdvanced Science, EarlyView.
β‐side chain elimination enables cost‐effective fused‐ring acceptors, JSM5 and JSM6, with simplified synthesis. The observed compact tetrameric structures induced by S···N intermolecular interactions lead to 3D charge transport and enhance intermolecular connectivity, delivering high short‐circuit current density up to 28 mA cm−2, a step closer to the ...
