Large-scale modular and uniformly thick origami-inspired adaptable and load-carrying structures

open access: yesNature Communications
Existing Civil Engineering structures have limited capability to adapt their configurations for new functions, non-stationary environments, or future reuse. Although origami principles provide capabilities of dense packaging and reconfiguration, existing

A New Type Microwave Absorption Materials: Metal–Organic‐Frameworks (MOFs) Used as Non‐Conductive Material Combination with P‐C‐800

open access: yesAdvanced Electronic Materials, EarlyView.
MOFs are considered a non‐conductive material and combined with biomass carbon materials as microwave absorbing materials, the composite exhibits excellent microwave absorbing performance. Abstract Metal–Organic‐Frameworks (MOFs) are commonly used as microwave‐absorbing materials after pyrolysis treatment.

Graphene/h‐BN/ReS2 Heterostructure Operating in Fowler−Nordheim Tunneling Regime for Polarization‐Sensitive Fast Photodetector

open access: yesAdvanced Electronic Materials, EarlyView.
The authors demonstrate a bias voltage‐dependent anisotropic tunneling behavior by designing a ReS2‐based heterojunction operating in the Fowler–Nordheim tunneling regime. The device exhibits a dichroic tunneling current that surpasses the intrinsic anisotropy of ReS2, offering a new strategy to amplify directional responses in 2D materials for ...

Transmission factors and exposure to infections at work and invasive pneumococcal disease

open access: yesAmerican Journal of Industrial Medicine, Volume 66, Issue 1, Page 65-74, January 2023., 2023
Abstract Background Working in close contacts with coworkers or the general public may be associated with transmission of invasive pneumococcal disease (IPD). We investigated whether crowded workplaces, sharing surfaces, and exposure to infections were factors associated with IPD.

Improved Direct Ink Writing of Liquid Metal Foams via Liquid Additives

open access: yesAdvanced Electronic Materials, EarlyView.
The ability to pattern liquid metal is useful for making soft electrical and thermal devices. Dispensing liquid metal from a nozzle naturally results in the formation of spheroidal droplets, making direct‐write printing challenging. Liquid metal foams containing pockets of air can extrude as filaments, albeit inconsistently.

Epidemiology of occupational injuries in construction workers between 2009 and 2018 in South Korea

open access: yesAmerican Journal of Industrial Medicine, Volume 66, Issue 2, Page 155-166, February 2023., 2023
Abstract Background This study aimed to investigate the characteristics of occupational injuries based on fatality, sex, and classification of occupations among construction workers using workers' compensation (WC) insurance data in South Korea. Methods We collected WC insurance data from the Korea Workers' Compensation & Welfare Service for all ...

Phase Transition in Halide Double Perovskites for Solar‐To‐Chemical Energy Conversion

open access: yesAdvanced Energy Materials, EarlyView.
Disorder‐to‐order phase transition in double perovskite Cs2AgBiBr6 eliminates self‐trapped excitons and antisite defects and promotes charge separation, with over sixfold photoactivity enhancement in photocatalytic C−H bond activation. Abstract Halide double perovskites have recently garnered significant interest in solar energy conversion applications

Few-shot crack image classification using clip based on bayesian optimization [PDF]

open access: yesarXiv
This study proposes a novel few-shot crack image classification model based on CLIP and Bayesian optimization. By combining multimodal information and Bayesian approach, the model achieves efficient classification of crack images in a small number of training samples.
