Advanced Science, EarlyView.This work presents an origami metamaterial that integrates a low‐melting‐point alloy skeleton into an elastomeric shell. It dissipates energy through the metal's plastic deformation and recovers through the solid–liquid phase transition of the alloy together with the hyperelasticity of the shell.

Relaxor Ferroelectricity Enables Enhanced Thermoelectric Performance in In2Se3‐Alloyed GeTe
Advanced Science, EarlyView.A non‐equimolar In3+/Se2− alloying strategy creates Ge vacancies in GeTe, inducing relaxor ferroelectricity that broadens the low thermal conductivity window. Simultaneously, cubic phase stabilization broadens optimal electrical transport, achieving an average zT > 1.0 over 330–625 K.

Characteristics of rotating instability in a centrifugal blower with shrouded impeller
Nihon Kikai Gakkai ronbunshu, 2014 The Rotating instability, abbreviated to RI, in a centrifugal blower with shrouded impeller is investigated by experiments and CFD analyses. The RI occurs in a partial-flow operation of the blower prior to stall with mild fluctuations of impeller ...

Temporary speed hump impact evaluation
, 2020 The main objective of this research was to evaluate the impact of temporary speed humps and speed tables on vehicle speeds, vehicle speed profiles, and traffic volumes along local and/or collector streets in several rural Iowa cities. A 25 mile per hour (mph) temporary speed hump and a 30 mph temporary speed table, both made of recycled rubber, were ...

Advanced Science, EarlyView.A “nutritional trap” strategy centered on disrupting bacterial iron homeostasis is proposed. The synthesized Bi‐TP@FU (TBF) can target Helicobacter pylori, interfere with the bacterial iron uptake and utilization processes to disrupt its iron homeostasis, induce bacterial death, and meanwhile preserve the balance of the intestinal flora.

Optimum design of speed control humps for vehicles.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1988 This paper deals with optimum design problems of humps for controlling vehicle speeds. Optimum humps are obtained for a segment of a circle in section using a method with a SUMT optimizing a hump for a vehicle. The objective of the design is to minimize the maximum acceleration of the driver occurring during a vehicle crossing a hump at a design speed ...

Advanced Science, EarlyView.Super‐multiplexed Label‐free Raman Imaging (SLRI) enables 2D/3D metabolic mapping of intact Drosophila testes. Moving beyond descriptive morphology, it establishes a multidimensional tool for tissue metabolic remodeling, and offers a generalizable platform for complex tissue analysis, with implications extending to development and disease. ABSTRACT The

Rail skates for fixing rolling stock on the station tracks. Ground tests
Вестник Научно-исследовательского института железнодорожного транспорта, 2016 Currently manual brake shoes on Russian railways are used to solve two main tasks: to adjust uncoupling speed at humps (hump shoes), and to fix the rolling stock on the railway tracks.
