First Operation Results of a Methanol Demonstration Plant With Real Steel Mill Gases

open access: yesChemie Ingenieur Technik, EarlyView.
A demonstration plant with industrial setup regarding length, diameter, boiling water cooling system and gas recycle was initially operated with cleaned blast furnace gas and compared with earlier experiments with bottle gases. Dynamic disturbances from the steel mill and gas cleaning unit were noticed and could be compensated by the control system ...

Power spectral density and the brain

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Time series from M/EEG (magneto/electroencephalography) and ECoG (electrocorticography) recordings are common sources of information about brain function. The power spectral density (PSD) preserves much of this information, up to second order. In the current decade, a burst of brain diagnostics using the slope of log(PSD) has appeared.

Directional and gradient patterning from sub‐microliter colloidal droplet evaporation on inclined and stretched soft substrates

open access: yesDroplet, EarlyView.
Instead of suppressing the ubiquitous “coffee‐ring” effect, we harness it by integrating stretching, inclination, and rotation of soft substrates. This sequential control allows manipulation of global pattern symmetry and local morphology. By incorporating substrate inclination and rotation of stretched soft substrates, we create diverse patterns that ...

Carbon emission assessment of tunnel infrastructures: From construction to operation

open access: yesDeep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Daily Ovarian Hormone Exposure and Loss of Control Eating in Adolescent Girls: A Stage 2 Registered Report

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective This Stage 2 Registered Report examined (1) the main effects and interaction of within‐person daily associations between ovarian hormones (i.e., estrogen, progesterone) and loss of control eating (LOCE), and (2) the within‐person mediating roles of food‐related reward anticipation and response inhibition. Methods Adolescent girls (n =

Triboelectric–Electromagnetic Generator‐Enabled Hybrid Power Backpack for Self‐Powered Field Safety Management

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A lightweight hybrid backpack integrating SC‐TENGs and R‐EMGs harvests biomechanical energy during walking. With a low activation speed of 3 km h−1 and a high specific power of 0.18 W kg−1, it enables self‐powered field safety management. The power backpack refers to an energy‐harvesting solution engineered to mitigate battery reliance in wearable ...

Assessment of the effects of microwave‐produced biodiesel blends on electric generator performance and emissions

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Biodiesels are emerging as alternatives to diesel fuel. However, to be a feasible solution, biodiesels must meet strict criteria including high efficiency and minimal environmental impact. The current study focuses on evaluating ethyl ester biodiesel and its blends with diesel fuel to assess their potential.
