RTRI's Large-scale Low-noise Wind Tunnel and Wind Tunnel Tests

Quarterly Report of RTRI, 2001
This article describes the specifications of the Large-scale Low-noise Wind Tunnel completed at Maibara, Japan in 1996. It is used to study aerodynamic noise and other aerodynamic phenomena related to the operation of high-speed trains and to test systems to reduce deleterious effects. Two features stand out: extremely low background noise and a device

From Behavior to Dynamics: Decoding Carrier Roles in Cu‐based Photocathodes for Solar‐Driven CO2 Reduction

Advanced Materials, EarlyView.
The performance of Cu‐based photocathodes in photoelectrochemical CO2 reduction is not governed by catalytic sites alone, but by the dynamic journey of photogenerated carriers. This review decodes how carrier generation, recombination, transport, accumulation, extraction, and electrolyte coupling shape catalytic activity, selectivity, and stability ...

An automated system for navigating object mounts within a wind tunnel facility [PDF]

EPJ Web of Conferences
From an engineering point of view, understanding how the flow behaves downstream from solid objects is essential. The current configuration of the Armfield subsonic wind tunnel (computer controlled C15 − 10 model) does not provide uniform guidance for ...

Electrically Coded Retinomorphic Spectrophotodetector

Advanced Materials, EarlyView.
Self‐powered retinomorphic pyro‐photodetector is demonstrated that avoids machine‐learning post‐processing and covers 365–940 nm. Electrostatic balancing of built‐in potential produces an electrical wavelength code, delivering <3 nm wavelength decoding accuracy with ∼46 µs response.

1‐D Collocated Dual‐Gradient Sensory Fibers for Comprehensive Sensing and Decoding of Complex Human Motion and Physiology

Advanced Materials, EarlyView.
Coupled materials design enables a monolithic fiber that integrates complementary sensing regimes into a single wearable strand. By preserving informative signal features across subtle physiological deformation, large body motion, and mixed mechanical inputs, the dual‐gradient architecture generates synchronized, less redundant outputs that improve ...

Measuring and Manipulating Density of States in Two‐Dimensional Materials With Electrochemical Capacitance

Advanced Materials Interfaces, EarlyView.
We report electrochemical quantum capacitance spectroscopy as an ambient, in situ probe for defect‐mediated electronic structure at 2D material interfaces. Using monolayer MoS2, the method resolves band edges and vacancy states, tracks sulfur‐vacancy evolution during hydrogen evolution, and links interfacial density‐of‐states changes to nearly ...

Bandgap‐Dependent Band‐to‐Band Tunneling in Carbon Nanotube Transistors

Advanced Materials Interfaces, EarlyView.
We systematically investigate bandgap‐dependent BTBT in SWCNT transistors by comparing wide‐bandgap (6,5) (Eg≈1.13 eV), medium‐bandgap HiPco, and narrow‐bandgap Arc‐discharge (Eg≈0.59 eV) SWCNT networks. The narrow‐bandgap networks show stronger BTBT, higher off‐state leakage, and lower on/off ratio, while wide‐bandgap (6,5) devices suppress BTBT and ...
