Cold-injection synthesis of highly emissive perovskite nanocrystals
Colloidal perovskite nanocrystal (PeNC) has long been synthesized using the hot-injection method and room-temperature ligand-assisted reprecipitation as the prominent techniques1,2. However, both methods have challenges for industrial-scale production3–5 : the hot-injection method requires high temperatures, an inert gas environment and rapid cooling, which raise safety concerns, whereas ligand-assisted reprecipitation can exhibit limited productivity on scale-up. Here we present a coldinjection

Recent Progress in Surface Engineering of AgBiS2 Nanocrystals for Nontoxic and Efficient Photovoltaics
Silver bismuth sulfide (AgBiS2) nanocrystals have recently emerged as eco-friendly semiconductors, achieving power conversion efficiencies above 10%. These improvements are largely driven by surface engineering, which reduces mid-gap states and enhances charge transport and film quality. This review summarizes four major surface engineering strategies for AgBiS2 NCs solid-state ligand exchange, solution-phase ligand exchange, direct synthesis, and full passivation, highlighting their principles

Spontaneous Penetration of Carbon Nanotubes through Lipid Bilayers: A Computational Perspective
Carbon nanotubes (CNTs) have been widely explored for applications ranging from drug delivery to energy conversion. To evaluate their potential as drug-delivery agents, it is essential to understand the molecular mechanisms governing their interactions with, and possible transport across, cell membranes. Molecular dynamics (MD) simulations provide a powerful framework for probing these processes at molecular resolution. In this study, we investigate the spontaneous membrane insertion and deep pe

Arabidopsis WSS1A, a DNA-protein crosslink repair protease, delays leaf senescence in cooperation with SUMO3
Leaf senescence, the final stage of leaf development, is regulated by complex interplays of intrinsic genetic programs and environmental cues. Throughout their lifetimes, all living organisms encounter various endogenous and environmental challenges, many of which can cause potentially fatal DNA damage. Among these, DNA-protein crosslinks (DPCs) are particularly deleterious, as they obstruct essential processes such as replication and transcription, thereby compromising genome integrity and ulti

Applications of flexible and stretchable three-dimensional structures for soft electronics
The development of devices that can be mechanically deformed in geometrical layouts, such as flexible/stretchable devices, is important for various applications. Conventional flexible/stretchable devices have been demonstrated using two-dimensional (2D) geometry, resulting in dimensional constraints on device operations and functionality limitations. Accordingly, expanding the dimensions in which such devices can operate and acquiring unique functionality that is difficult to implement in 2D pla

Precise Synchronization Between LiDAR and Multiple Cameras for Autonomous Driving: An Adaptive Approach
LiDAR and camera are crucial perception sensors that provide complementary information for object detection in autonomous driving vehicles. However, the fusion of sensor data to achieve efficient object detection requires accurate calibration and precise time synchronization between the sensors. While calibration ensures the geometric relationship between the sensors, and time synchronization ensures that data from both sensors corresponds to the same moment in the real world. Even though variou

Recent Advances in Ultra-High-Speed Wireline Receivers with ADC-DSP-Based Equalizers
High-speed wireline data transceivers (TRX) with analog-to-digital converter (ADC) followed by digital signal processor (DSP) on the receiver (RX) equalizer became popular for applications requiring >100 Gb/s per-lane data rate over long-reach (LR) channels, especially for datacenter applications. With the digital-to-analog converter (DAC)-based transmitter (TX) including DSP-based TX signal processing, the overall structure of DAC/ADC-DSP-based wireline TRXs became similar to modulator/demodula

Edge-Server Workload Characterization in Vehicular Computation Offloading: Semantics and Empirical Analysis
Edge server-assisted computation offloading enables vehicles to leverage server compute resources to deliver connected services, overcoming the limitations of onboard resources. Understanding the compute workloads of edge servers is crucial for effective resource management and scheduling, yet this task is challenging due to the complex interplay of factors such as vehicle mobility and computation offloading patterns. To address this, we propose an empirical analysis framework that systematicall
