Enhancing Quantum Dot Photovoltaic Efficiency Through Defect Passivation and Triplet Energy Transfer with 9-Anthracenecarboxylic Acid
A dual-functional electron transport layer (ETL) is reported for PbS colloidal quantum dot (CQD) photovoltaics by incorporating 9-anthracenecarboxylic acid (ACA) into a zinc oxide (ZnO) matrix. Despite its favorable electron transport characteristics and appropriate band alignment, intrinsic defects in ZnO, such as oxygen vacancies, remain a limiting factor in device performance. The carboxylate functional group of ACA effectively passivates these defects, thereby reducing trap-assisted recombin

Understanding the role of gas diffusion electrodes in steering the CO2 electroreduction pathway
Electrochemical CO2 reduction reaction (CO2 RR) offers a promising route for converting CO2 into value-added chemicals. GDEs are pivotal for pushing CO2 RR toward industrial competitiveness, yet the GDE macro- and nano-structural parameters and their relationship with CO2 RR performance remain unclear. Here, we experimentally quantified the intrinsic and extrinsic properties of Cu-based GDEs (28BC, 22BB, 39BB, 36BB) and their CO2 RR p

Waste polyethylene-coated fabrics for dual-mode interfaces triboelectrification for self-powered sensors
The reuse of waste cotton textiles and coating them with recycled polyethylene provides a route to improve environmental sustainability, reducing our landfill burden and supporting the circular economy through effective implementation of the 3Rs: Reduce, Reuse, and Recycle. This approach extends material life and minimizes resource consumption. This study presents a sustainable strategy for energy harvesting and sensor applications by repurposing worn-out cotton textiles that are coated with rec

Durable alkaline zinc-iron flow batteries using a SPEEK/Polysulfone blend membrane
Alkaline zinc-iron flow batteries (AZIFBs) are regarded as one of the most promising candidates for energy storage systems (ESSs). Although they have advantages, such as scalability, safety, and long cycle life, there are remaining disadvantages - crossover and zinc dendrite formation. To address these issues, we introduce a blend polymer membrane for a stable zinc-iron flow battery system with enhanced alkaline stability and dendrite-free operation. The SPEEK/Polysulfone (SPK/PS) blend membrane

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

Assessing dietary specialization to inform the conservation of the fairy pitta (Pitta nympha), an endangered vermivore
Quantifying the diet of endangered species is crucial for conservation, especially for diet specialists, which can be more susceptible to environmental changes. The vulnerable fairy pitta (Pitta nympha) is considered a specialist that primarily feeds its nestlings with earthworms. However, there have been few studies of the nestling diet provisioned by parents, and no assessments of earthworm proportion in the diet of adults. Our study aimed to fill these gaps, shedding light on crucial factors

한국문학 번역과 번역 비평의 가능성 - The Vegetarian의 사례를 중심으로
본고에서는 한강의 소설 『채식주의자』의 영어본 텍스트인 The Vegetarian을 둘러싼 오역 논쟁을 메타적으로 검토하고, 가시화된 문학 번역을 둘러싼 논점을 예각화화면서, 그간 본격화되지 못했던 번역 비평을 시도하였다. The Vegetarian의 국제문학상 수상 이후로 문학 번역에 대한 논의가 시작되었으나, 그 논의는 오역 논쟁에 갇혀 문학 번역에 대한 심도 깊은 논의로 진전되지 못했다. 번역은 언어 간, 국가 간, 문화 간, 텍스트 간 권력 관계의 불균형성이 중첩된 위계 구조를 온몸으로 통과하는 일이며, 그 권력의 불균형성은 번역가의 위치성을 통해 가시화되는 것이기도 하다. 본고에서는 문학 번역을 번역의 정치성과 번역가의 위치성으로 가시화되는 권력 문제의 차원으로 이해하면서, 오역 논쟁을 문학 번역의 이론적 실천 과정과의 관련 속에서 비판적으로 검토하였다. The Vegetarian을 둘러싼 오역 논쟁의 이면에 가려진 권력의 문제는 번역 비평이 왜 번역의 윤리학과 정치학에 대
