Hydraulic traits exert greater limitations on tree-level maximum sap flux density than photosynthetic ability: Global evidence.

Transpiration is a key process that couples the land-atmosphere exchange of water and carbon, and its maximum water transport ability affects plant productivity. Functional traits significantly influence the maximum transpiration rate; however, which factor plays the dominant role remains unknown. SAPFLUXNET dataset, which includes sap flux density of diverse species worldwide, provides fundamental data to test the importance of photosynthetic and hydraulic traits on maximum tree-level sap flux density (J).

Influence of interpersonal relationship on subjective well-being of college students: The mediating role of psychological capital.

Background: Nowadays, the contradiction between the rapid improvement of people's material living standard and the loss of spiritual pursuit or the increase of pressure is becoming more and more serious.With the impact of the new corona-virus pandemic, the employment situation of college students is more severe. This leads to the growth of psychological problems and alienation behavior of college students.

Deciphering global patterns of forest canopy rainfall interception (FCRI): A synthesis of geographical, forest species, and methodological influences.

Forest canopy rainfall interception (FRCI) is an essential hydrological process that governs water and biogeochemical cycles in forest ecosystems. Identifying patterns and relationships of FCRI using a systematic review is key to improving our knowledge supporting new experiment research, modeling, and application. In this meta-analysis, we aimed to delineate the canopy interception (CI), throughfall (TF), and stemflow (SF) concerning geographical and forest variables and experimental methodologies.

Integration of hydrothermal liquefaction of Cyanophyta and supercritical water oxidation of its aqueous phase products: Biocrude production and nutrient removal.

Cyanophyta has the potential to produce biocrude via hydrothermal liquefaction (HTL). However, aqueous phase products (APs), as by-products of HTL, pose a risk of eutrophication for the high levels of carbon, nitrogen, and phosphorus. Supercritical water oxidation (SCWO) can efficiently convert organics into small molecules, offering a technique for the harmless treatment of APs.

Multi-stage adsorption of methyl orange on the nitrogen-rich biomass-derived carbon adsorbent: DFT and MD evaluation.

Dyes that are released into the environment may have negative effects on living organisms. To address this issue, a biomass-derived carbon adsorbent made from Enteromorpha was tested for its ability to remove methyl orange (MO) from wastewater. The adsorbent was found to be effective in removing MO, with a 1:4 impregnation ratio producing an adsorbent that could remove 96.

Facile synthesis of chlorella-derived autogenous N-doped porous biochar for adsorption on tetracycline.

In this study, an autogenous N-doped biochar derived from Chlorella (CVAC) was prepared with NaOH as activator at 800 °C. The surface structural properties of CVAC and the adsorption performance of CVAC on tetracycline (TC) under different adsorption variables were analyzed and investigated using different characterization methods. The results showed that the specific surface area of CVAC was 491.

Copyrolysis of microalga Chlorella sp. and alkali lignin with potassium carbonate impregnation for synergistic Bisphenol A plasticizer adsorption.

Composite functional materials offer promising opportunities for the development of tailored adsorbents with enhanced bioremediation potential towards toxic, carcinogenic endocrine disrupters such as Bisphenol A (BPA). Copyrolysis of microalga Chlorella sp. (CH) alkali lignin (L) with KCO impregnation yielded a carbon-based composite (CHL-AC) with a micro-mesoporous structure of 0.

Response surface optimization of product yields and biofuel quality during fast hydrothermal liquefaction of a highly CO-tolerant microalgae.

The effects of biochemical components and processing variables (e.g., temperatures, solid-liquid ratio, ethanol concentration, and time) during fast hydrothermal liquefaction of a highly CO-tolerant microalgae (Micractinium sp.

Highly efficient adsorption of Bisphenol A using NaHCO/CO activated carbon composite derived from shrimp shell@cellulose.

In this study, the efficiency of activated carbon (AC) synthesized from the shrimp shell plus cellulose (SS@C) was optimized toward Bisphenol A (BPA) adsorption. Low-cost, renewable, and non-toxic shrimp shells mixed with cellulose were carbonized, followed by activation via CO and NaHCO to produce SS@C-AC. The results revealed that SS@C-AC samples were a porous composite with mesoporous structures comprising a relatively high specific surface area (935.

Incremental learning for detection in X-ray luggage perspective images.

Convolutional neural networks have achieved remarkable results in the detection of X-ray luggage contraband. However, with an increase in contraband classes and substantial artificial transformation, the offline network training method has been unable to accurately detect the rapidly growing new classes of contraband. The current model cannot incrementally learn the newly appearing classes in real time without retraining the model.

Adsorption modeling, thermodynamics, and DFT simulation of tetracycline onto mesoporous and high-surface-area NaOH-activated macroalgae carbon.

Activated carbon (ENAC) was prepared by NaOH activation, using macroalgae (Enteromorpha clathrate) as raw material. The prepared activated carbon has a large surface area (1238.491 m g) and its total pore volume and average pore size are 0.

Study on pressurized upgradation of pyrolysis oil for high-value liquid products.

Upgradation of pyrolysis oil is a key process to achieve high-quality biofuel. In this study, the effects of different Ar pressures and H/Ar ratios in the presence and absence of catalysts on deoxygenation of pyrolysis oil were investigated by autoclaving. When the initial pressure of the reaction is 6MPa and without catalyst addition, the content of carboxylic acid decreases from 51.

Study on two-step hydrothermal liquefaction of macroalgae for improving bio-oil.

In this work, the conversion of Enteromorpha clathrata into bio-oil through hydrothermal liquefaction (HTL) was investigated under different preparation conditions. A two-step reaction method was compared with single-step reaction. At a high temperature, bio-oil produced through the two-step hydrothermal reaction displayed slight changes in yield, but solid residue rate was low.

Sky islands as foci for divergence of fig trees and their pollinators in southwest China.

The dynamics of populations and their divergence over time have shaped current levels of biodiversity and in the case of the "sky islands" of mountainous southwest (SW) China have resulted in an area of exceptional botanical diversity. Ficus tikoua is a prostrate fig tree subendemic to the area that displays unique intraspecific diversity, producing figs typical of different pollination modes in different parts of its range. By combining climate models, genetic variation in populations of the tree's obligate fig wasp pollinators and distributions of the different plant phenotypes, we examined how this unusual situation may have developed.
