The Critical Role of Economies of Scale: A Techno‐Economic Assessment of Small‐ Versus Large‐Scale Biogas Upgrading in Rural Tanzania

ABSTRACT Access to clean and affordable energy remains a major challenge in rural Tanzania, where dependence on traditional biomass continues to drive deforestation, indoor air pollution, and energy insecurity. Biogas offers a promising alternative, yet limited evidence exists on...

More is not always better: Dissociative photoionization limits the EUV absorbing photoacid generator pentafluorophenyl triflate in photolithography

Pentafluorophenyl triflate has been explored as a highly absorbing neutral photoacid generator (PAG) candidate for next-generation chemically amplified resists used in extreme ultraviolet (EUV) lithography. Although increased fluorination enhances EUV absorption, this study demon...

Discrete time survival analysis machine learning models for IVF prognosis across multiple cycles

Abstract STUDY QUESTION Can discrete time survival analysis machine learning (ML) methods provide reliable and accurate predictions of cumulative live birth rate (CLBR) for patients both at diagnosis (pre-treatment) and after the first cycle of treatment (post-treatment)? SUMMARY...

Addressing evidence gaps in haemodialysis care: a critical review of clinical trials, technological innovations, and implementation priorities

Kidney failure treated with maintenance haemodialysis (HD) carries high risks of premature mortality, hospitalisation and impaired quality of life, yet important evidence gaps persist across routine HD care. The Dialysis Research Innovation Network, part of the UK Kidney Research...

Vertical Compressive Stress in Fab-Integrated WS2 FETs: An In Situ Electrical and Nanoindentation-Based Study

Abstract Two-dimensional (2D) semiconductors are sensitive to mechanical stress due to their atomic thickness, weak van der Waals interfaces, and ultra-high sensitivity to the surrounding dielectric environment. While the effects of in-plane strain in transition-metal dichalcogen...

Graphene-based Photodetector with Engineered Hot-Carrier Cooling Dynamics

Abstract Graphene has emerged as a promising material for integration into silicon photonics, owing to its ultrafast and broadband photoresponse without the need for an external bias voltage. This photoresponse relies on the photo-thermoelectric effect created by hot carriers. A...

Graphene Field-Effect Transistor Process and Analysis Optimization in 200 mm Pilot-Line Environment

Abstract The maturity of the chemical vapor deposition graphene-based device processing has increased from chip-level demonstrations to wafer-scale fabrication in the past few years. Due to this, wafer-scale electrical characterization and analysis of the fabricated devices have...

Modeling of flopping-mode spin qubits: Beyond the two-site model

We present a flexible modeling framework for flopping-mode spin qubits that captures the spatial structure of the double-well confinement and magnetic-field-gradient profile going beyond conventional low-energy descriptions. By using this approach, we simulate electric dipole spi...
