Enhancing energy efficiency is essential for proton exchange membrane fuel cells (PEMFCs) operating in a dead-ended anode (DEA) mode. This study proposes the integration of a buffer tank, positioned between the mass flow meter and the fuel cell, to reduce hydrogen loss during purge events. The buffe...

Three different chlorophyll-deficient rice isogenic lines chl, fgl and pgl, and their recurrent parent zhefu802 (zf802) were used to study effects of leaf color on photosynthesis, dry matter accumulation, yield, and quality in early season indica rice. Analysis showed that the chlorophyll (Chl.) a/b...

Both biosystems and engineering fields demand advanced friction-reducing and lubricating materials. Due to their hydrophilicity and tissue-mimicking properties, hydrogels are ideal candidates for use as lubricants in water-based environments. They are particularly well-suited for applications involv...

Guided mode resonance (GMR) sensors are known for their ultrasensitive and label-free detection, achieved by assessing refractive index (RI) variations on grating surfaces. However, conventional systems often require manual adjustments, which limits their practical applicability. Therefore, this stu...

Nitrogen (N) and potassium (K) are two key mineral nutrient elements involved in rice growth. Accurate diagnosis of N and K status is very important for the rational application of fertilizers at a specific rice growth stage. Therefore, we propose a hybrid model for diagnosing rice nutrient levels a...

We presents the first complete mitochondrial genome of Pyrocoelia amplissima (Olivier, 1886) (Coleoptera: Lampyridae: Pyrocoelia), a Chinese endemic firefly. The 17,426 bp circular genome contains 13 PCGs, 23 tRNAs, 2 rRNAs, and a control region with a notable A + T bias (76.91%). Phylogenetic analy...

Cellulose, a major constituent of plant biomass, is synthesized by a cellulose synthase complex. It has been demonstrated that MYB genes transcriptionally regulate cellulose synthase in Arabidopsis. However, little is known about this process in tomato. Here, two MYB (SIMYB1/2) and three cellulose s...

Environmental conditions greatly affect the growth of rice. To investigate the geographic differences in yield formation of single-season high-yielding hybrid rice in southern China, experiments were conducted in 2017 and 2018 in the upper and middle–ower reaches of the Yangtze River with 10–30 main...

Context: The efficient and precise monitoring of rice leaf area (LA) is essential for variety selection and agricultural management. At present, LA estimation models based on high-throughput phenotyping technologies primarily depend on homogenized large sample datasets. These models encounter genera...

Rapeseed is a very important oil crop in China; however, its production is challenging due to the absence of effective weed management strategies. This is predominantly because of a shortage of herbicide resistance genes. Acetohydroxyacid synthase (AHAS) herbicides inhibit AHAS, a key enzyme involve...
