Programmable ultrasonic modulation of viscoelasticity in polymer-based elastomers: Experiments and constitutive modeling.

Ultrason Sonochem

August 2025

School of Mechatronics Engineering, Harbin Institute of Technology, Harbin, 150001, People's Republic of China. Electronic address:

One of the central challenges in soft matter mechanics is to achieve reversible and programmable modulation of viscoelasticity in polymer-based elastomers at small strains, which is crucial for precision engineering and advanced functional devices. Conventional approaches are constrained by irreversibility and lack of dynamic control. In this study, it is demonstrated that ultrasonic vibration (19-22 kHz) enables dynamic, reversible, and tunable modulation of the mechanical response in such materials.

Reactive transport in porous media is the key to heterogeneous catalysis, which is the central process in both natural and engineered systems. Elucidating nexus between porous architecture and reactive transport is of importance, but remains a challenge. Conventional text-based approach relies on quantitative structural features (QSFs; porosity, tortuosity, and connectivity), which fails to identify key reaction regions and predict local reaction rate for anisotropic architecture due to isotropic assumption.

Naturally powdered metal-organic frameworks (MOFs) usually require packing for practical applications, where intercrystal interactions play pivotal roles. Herein, using an atomic force microscope with a MOF HKUST-1 crystallite-tipped probe, we directly find that the intercrystal adhesion energy of as-synthesized HKUST-1 with adsorbed water molecules is quadruple that of its activated counterpart. A similar large enhancement in the intercrystal adhesion energy of HKUST-1 due to water adsorption is also observed in molecular dynamics simulations, which is ascribed to the formation of strongly interacting hydrogen-bond networks, driven by copper paddlewheels massively exposed on HKUST-1 surfaces and intercalated water molecules adsorbed in surface cavities.

AI may exacerbate the energy trilemma.

Integr Environ Assess Manag

September 2025

Department of Management, Harbin Institute of Technology, Harbin, China.

The rapid expansion of artificial intelligence (AI) is intensifying the global energy trilemma, threatening security, equity, and sustainability. Its soaring electricity demand-projected to rival Japan's entire annual consumption by 2030-is the primary driver. This surge poses a direct threat to energy security, as demand growth dramatically outpaces grid infrastructure development and provokes regional power crises.

Accurate image quality evaluation is essential for optimizing sensor performance and enhancing the fidelity of visual data. The concept of "image style" encompasses the overall visual characteristics of an image, including elements such as colors, textures, shapes, lines, strokes, and other visual components. In this paper, we propose a novel full-reference image quality assessment (FR-IQA) method that leverages the principles of style transfer, which we call style- and content-based IQA (SCIQA).

Low-temperature plasma cleaning technology has been widely used to clean various optical components precisely. After the complete removal of organic contaminants from fused silica surfaces through plasma cleaning, continuous plasma irradiation can lead to nano-defects on the fused silica surface, resulting in the degradation of optical performance. Thus, the microscale processes underlying plasma-induced surface damage on fused silica were investigated through molecular dynamics simulations, aiming to analyze the mechanisms of surface damage on optical components during plasma cleaning.

With the development of urban infrastructure construction, while pedestrian bridges meet traffic functions the issue of their comfort has become a core consideration in structural design. This is because the long-span lightweight structures, with their large flexibility and low fundamental frequencies, are also vulnerable to human-induced vibrations. Pedestrian load modellings include the deterministic time-domain model, which is widely adopted in codes due to its simplicity, the random model that takes into account individual variability, and the frequency-domain model.

A novel honeycomb with gradient-thickness cell walls (HGTCWs) is fabricated through chemical etching to achieve progressive thickness reduction in the cell walls. This engineered honeycomb demonstrates superior energy absorption by effectively eliminating the peak load during the linear elastic stage of the load-displacement curve under impact loading, thereby preventing premature structural failure caused by excessive instantaneous loads. To systematically investigate the impact compression mechanics, energy absorption characteristics, and key influencing factors of aluminum HGTCWs, a three-factor orthogonal array of low-velocity impact experiments was designed.
