Rational design of CT-coupled J-aggregation platform based on Aza-BODIPY for highly efficient phototherapy.

Supramolecular engineering is exceptionally appealing in the design of functional materials, and J-aggregates resulting from noncovalent interactions offer intriguing features. However, building J-aggregation platforms remains a significant challenge. Herein, we report 3,5-dithienyl Aza-BODIPYs with a donor-acceptor-donor (D-A-D) architecture as the first charge transfer (CT)-coupled J-aggregation BODIPY-type platform.

Hydraulic Expansion Joint Contact State of Heat Exchanger Based on New Contact Area Measurement Method.

The contact state of a seamless internal threaded copper tube and an aluminium foil fin not only affects the heat transfer efficiency of a tube-fin heat exchanger but also seriously affects its service life. In this study, hydraulic expansion technology was used to connect the copper tube with an internal thread with a 7 mm diameter to the fin of the heat exchanger. The influence of the expansion pressure and pressure holding time on the contact state was analysed through experiments and finite element simulation, and the variation law of the two on the contact state was obtained.

Novel organoboron complexes with robust core: Synthesis, functionalization, and subcellular targeting.

The construction of novel organoboron complexes with facile synthesis and unique advantages for biological imaging remains a challenge and thus has garnered considerable attention. Herein, we developed a new molecular platform, boron indolin-3-one-pyrrol (BOIN3OPY) via a two-step sequential reaction. The molecular core is robust enough to allow for post-functionalization to produce versatile dyes.

HS-mediated balance regulation of stomatal and non-stomatal factors responding to drought stress in Chinese cabbage.

Increased evidence has shown that hydrogen sulfide (HS), a novel gasotransmitter, could enhance drought resistance in plants by inducing stomatal closure, with concurrent enhancement of photosynthetic efficiency, but little is known about the mechanism behind this contradictory phenomenon. This study examined the regulating mechanism of HS in response to drought stress from stomatal and non-stomatal factors in Chinese cabbage. The results showed that exogenous HS could increase the accumulation of photosynthetic pigments and alleviate the damage caused by drought stress.

Response of Juvenile to the Combined Stressors of Elevated pCO and Excess Copper.

Coastal macroalgae may be subjected to global and local environmental stressors, such as ocean acidification and heavy-metal pollution. We investigated the growth, photosynthetic characteristics, and biochemical compositions of juvenile sporophytes of cultivated at two pCO levels (400 and 1000 ppmv) and four copper concentrations (natural seawater, control; 0.2 μM, low level; 0.

Fixing sulfur dioxide by feeding calcine oxide into the rotary volatilization kiln in zinc smelting plant.

Sulfur dioxide (SO) is a toxic pollutant and its fixation is a high cost but imperative task for sulfide metallurgy industry. Although being a mature technology for on-line fixation of SO by limestone injection in coal-fired boilers, its application is rarely investigated in the sulfide metallurgy plant. Extending this technology to the metallurgy industry is highly plausible, but with the feasibility and practicability waiting to be uncovered.

Decreased Salinity Offsets the Stimulation of Elevated pCO on Photosynthesis and Synergistically Inhibits the Growth of Juvenile Sporophyte of (Laminariaceae, Phaeophyta).

The combined effect of elevated pCO (Partial Pressure of Carbon Dioxide) and decreased salinity, which is mainly caused by freshwater input, on the growth and physiological traits of algae has been poorly assessed. In order to investigate their individual and interactive effects on the development of commercially farmed algae, the juvenile sporophytes of were cultivated under different levels of salinity (30, 25 and 20 psu) and pCO (400 and 1000 µatm). Individually, decreased salinity significantly reduced the growth rate and pigments of , indicating that the alga was low-salinity stressed.

Novel single-armed nitrogen-heterocyclic salamo-based fluorescent sensors for the detection of Al and CN.

Two novel single-armed nitrogen-heterocyclic chemosensors with basically similar structures, PDNS and PZNS, were synthesized to specifically identify Al in DMS:HO (1:1 v/v) solution by fluorescence emission spectroscopy, and the colour of PDNS and PZNS changed from yellow to colorless when Al was added under daylight.

At excitation wavelengths of 361 and 365 nm, solutions of PDNS and PZNS changed to intense green-blue fluorescence.

Auxin is involved in arbuscular mycorrhizal fungi-promoted tomato growth and NADP-malic enzymes expression in continuous cropping substrates.

Background: Despite significant limitations of growth medium reuse, a large amount of organic substrate is reused in soilless cultivation of horticultural crops in China. Arbuscular mycorrhizal fungi (AMF) can promote nutrient absorption and improve plant tolerance to biotic and abiotic stresses. However, the mechanisms governing the effects of AMF on crop growth in organic continuous cropping substrates have not been elucidated.
