Thermal niche breadth shapes regional elevational range sizes of tropical‐like mountain stream insects: evidence for Janzen's tropical mountain passes hypothesis

open access: yesEcography, EarlyView.
The core of Janzen's tropical mountain passes hypothesis is that relatively stable annual temperature variation limits species' thermal tolerances breadth, which, in combination with steep elevational temperature gradients, constrains the elevational distributions of these species. In addition to thermal niche breadth, elevational ranges were shaped by

Using satellite-derived backscattering coefficients in addition to chlorophyll data to constrain a simple marine biogeochemical model [PDF]

open access: yesBiogeosciences, 2009
Biogeochemical models of the ocean carbon cycle are frequently validated by, or tuned to, satellite chlorophyll data. However, ocean carbon cycle models are required to accurately model the movement of carbon, not chlorophyll, and due to the high ...

Natural Anthraquinone‐Like Compound Extracted from Green Husk of Walnut Improves Photocatalytic H2O2 Production Catalyzed by TiO2 Nanoparticles

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, a novel biomolecule/semiconductor hybrid catalyst was prepared by loading anthraquinone‐liked juglone onto anatase TiO2. This catalyst exhibited high photocatalytic activity for H2O2 production. Hydrogen peroxide (H2O2) is a vital oxidant with broad industrial applications, and its production via photocatalysis represents a highly ...

Comparative Analysis of Al2O3/Water–TiO2/Chlorophyll Hybrid Nanofluids in a Photovoltaic–Thermal Solar Water Heating System

open access: yesEnergy Science &Engineering, EarlyView.
TiO2/chlorophyll bio‐hybrid nanofluid achieved the highest PVT performance, increasing thermal efficiency to 38.74% and overall efficiency to 51.35%, compared with 35.96% and 48.45% for Al2O3/water and 27.77% and 40.18% for water. The results demonstrate the potential of bio‐hybrid nanofluids for high‐efficiency solar thermal energy conversion ...

Optimized Copper Pretreatment Protocols for Premium Green Raisin Production via Vacuum Impregnation and Metallo‐Complex Stabilization

open access: yesFuture Postharvest and Food, EarlyView.
ABSTRACT Green raisin production is limited by rapid chlorophyll degradation during drying. This study evaluated copper metallo‐complex formation to stabilize green pigmentation in Vitis vinifera cv. Thompson Seedless grapes. Pretreatments with copper sulfate (CuSO4) pentahydrate (2%–6% w/v) were applied via dipping and vacuum impregnation (2–10 min ...

Genetic and Molecular Basis of Processing Traits and Genetic Improvement Progress in Major Fruit Crops

open access: yesFuture Postharvest and Food, EarlyView.
Processing quality in fruit crops is governed by complex genetic networks controlling texture, sweetness, color, browning, aroma, and nutritional quality. Advances in genomics, genomic selection, and genome editing enable the development of processing‐oriented cultivars with improved industrial performance, reduced postharvest losses, and enhanced ...
