Ultra‐stretchable, super‐tough, and highly stable ion‐doped hydrogel for advanced robotic applications and human motion sensing

  •  13 February 2025

Graphical Abstract

Ultra-stretchable, super-tough, and highly stable ion-doped hydrogel for advanced robotic applications and human motion sensing Issue ,

Although hydrogel-based sensors are recognized as key players in human motion interaction technologies, their commercialization is still hindered by stability issues, primarily due to their high water content. In this work, a smart sensory glove is developed using an innovative ionic hydrogel with exceptional mechanical, anti-freezing, and anti-drying properties and, thereby, unprecedented stability. Such smart gloves have significant potential for real-time robotic tasks in a smart laboratory setting, as well as for integration with VR and AR technologies for training, troubleshooting, and collaborative work across different geographical locations.

Enhanced cryogenic thermoelectric cooling of Bi0.5Sb1.5Te3 by carrier optimization

  •  12 February 2025

Graphical Abstract

Enhanced cryogenic thermoelectric cooling of Bi0.5Sb1.5Te3 by carrier optimization Issue ,

Solid-state thermoelectric cooling techniques hold vast application prospects across many cryogenic fields. This work proposes an effective strategy to improve the cooling capability of p-type Bi0.5Sb1.5Te3 through careful control of carrier optimization. A 10% improvement in cooling performance at 180 K compared to existing commercial thermoelectric coolers is realized, demonstrating the extended cooling capability of thermoelectric coolers at cryogenic temperatures.

Graphical Abstract

Inkjet-printed reconfigurable and recyclable memristors on paper Issue ,

In this work, we focus on using sustainable production and additive manufacturing processes to fabricate high-yield, recyclable, multifunctional, and reconfigurable memristors on paper-based substrates. Reconfigurable memristors can mimic the functions of neurons and synapses, thereby simplifying the structure of neuromorphic computing systems. This approach unlocks potential for environmentally friendly neuromorphic electronics with applications in artificial intelligence and smart packaging.

All physical reservoir computing system with tunable temporal dynamics for multi‐timescale information processing

  •  10 February 2025

Graphical Abstract

All physical reservoir computing system with tunable temporal dynamics for multi-timescale information processing Issue ,

Leveraging the modulation effect of oxygen vacancies on the energy barrier, a homogeneously integrated all-PRC system with tunable temporal dynamics is constructed. The broad range ratio of temporal characteristic (>102) of the reservoir enables PRC to process information across multi-timescale. The constructed PRC is expected to assist visually impaired individuals in recognizing the type and distance of obstacles.

Polycyclization decorated organoboron emitters with hetero[8]helicenes electronic structure for highly‐efficient and stable narrowband circularly polarized electroluminescence

  •  27 January 2025

Graphical Abstract

Polycyclization decorated organoboron emitters with hetero[8]helicenes electronic structure for highly-efficient and stable narrowband circularly polarized electroluminescence Issue ,

The first two pairs of geometrical hetero[8]helicenes enantiomers are developed and demonstrate that a large helicity of helicene electronic structure is required to balance both high luminescence dissymmetry factor (glum) and efficiency, simultaneously realizing a high EQE of 31.7%, an electroluminescence glum of +5.23/−5.07 × 10−3 and a long LT95 of 731 h at an initial luminance of 1000 cd/m2 in OLEDs.
