Engineering Biochar‐Derived Functional Materials for High‐Performance Supercapacitors: Design Principles, Mechanisms, and Scalable Strategies

open access: yesCarbon Energy, EarlyView.
ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Energy‐Efficient Induction Carbonization: Tailoring Pore Structures in Hard Carbon Anodes Toward Enhanced Electrochemical Performance

open access: yesCarbon Energy, EarlyView.
ABSTRACT Hard carbon (HC) is currently the predominant anode material for sodium‐ion batteries; however, its practical application is still limited by insufficient initial Coulombic efficiency (ICE) and plateau capacity. Meanwhile, conventional HC production relies on energy‐intensive carbonization processes with considerable carbon emissions. Here, an

Modified F‐tests for assessing tree radial growth under linear‐circular regression models with correlated errors: A comprehensive toolbox rooted in G. E. P. Box's theorems

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Annual tree growth is a complex biological process. Modelling radial growth in the trunk by linear‐circular regression with one mode and correlated errors has allowed the definition and assessment of a preferred direction for 1 and 2 years. Here, modified F$$ F $$‐tests are presented for 3 years, 1 mode/year; 1 year, 2 modes for possible main ...

A Rare Initial Presentation of Gastric Cancer with Multiple Osteolytic Lesions

open access: yesCase Reports in Oncological Medicine, 2015
Gastric cancer is the 12th leading cause of cancer-related deaths in the United States and commonly metastasizes to the bones. However, the presentation of gastric cancer as bony metastases without preceding gastrointestinal symptoms is rare which has ...

Biomass‐derived hydrochars as eco‐friendly adsorbents for wastewater treatment applications

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Emerging organic pollutants (EOPs), such as diethyl phthalate (DEP), bisphenol A (BPA), and methylene blue (MB), are only partially removed in conventional wastewater treatment plants. This study assesses hydrochars produced by hydrothermal carbonization (HTC) of spruce bark (SB), vine shoots (VSs), and wheat straw (WSs) for removing three ...

The Influence of Certain Types of Substrate and Biochemical Substances in Seed Germination and Plant Development of Spruce (Picea abies)

open access: yesBulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Horticulture, 2020
In order to analyse seeds germination and seedlings growth of spruce (Picea abies) there were used five treatments with bio and chemical substances for stimulation germination: H2O, Atonik, Cropmax, CuSO4, KMnO4 and five treatments with different ...
