Modelling eccentrically loaded high-strength concrete columns

open access: yes, 2003
Based on a confined concrete model for concentric static loading, an analytical method is proposed to predict the behaviour of laterally confined concrete columns subjected to eccentric static loading.

Substrate Engineering of SWCNT p–n Junctions for Dual‐Mode Power Generation and Heat‐Flux Sensing

open access: yesAdvanced Science, EarlyView.
Through substrate engineering alone, a single‐walled carbon nanotube p–n junction device switches between two functions under uniform infrared irradiation. A low‐absorbance substrate sustains a central hot junction for continuous power generation, whereas high‐absorbance substrates transiently invert the temperature gradient for sensitive heat‐flux ...

Self‐Assembly of Organic–Inorganic Copolymers Toward Bio‐Inspired Cementitious Composites

open access: yesAdvanced Science, EarlyView.
Organic–inorganic copolymerization of calcium silicate hydrate and thioctic acid produces a self‐organized nanocomposite inspired by the disordered collagen–mineral architecture of trabecular bone. The resulting material combines a compressive strength above 300 MPa with intrinsic physical reprocessibility, retaining over 80% of its strength and energy

Understanding and Regulating C–N Coupling Pathways for Electrocatalytic Urea Synthesis From CO2 and NO3−/NO2−

open access: yesAdvanced Science, EarlyView.
Understanding and regulating C–N coupling is central to electrocatalytic urea synthesis from CO2 and NO3−/NO2−. This review outlines representative coupling pathways, summarizes carbon‐ and nitrogen‐side intermediate regulation strategies, and highlights in situ/operando tools for mechanistic clarification and catalyst design. ABSTRACT Electrocatalytic

Probabilistic Computing via Gate‐Tunable Random Telegraph Noise

open access: yesAdvanced Science, EarlyView.
Intrinsic random telegraph noise in metal–oxide–semiconductor field‐effect transistors is harnessed to create gate‐tunable probabilistic bits. By modulating carrier‐trapping dynamics, the device produces stochastic binary outputs with a continuous bias‐to‐probability transfer.
