Bifunctional tubular step-scheme CoS/CdS heterostructure for highly efficient photoelectrochemical detection coupled with the degradation of tetracycline.

A bifunctional tubular step-scheme CoS/CdS heterostructure was successfully synthesized for efficient photoelectrochemical (PEC) detection coupled with the degradation of tetracycline (TC). It was found that so-obtained heterostructure could effectively suppress the recombination of photo-generated carriers and display larger PEC responses owing to the internal electrostatic field. Upon adding TC, the photocurrent signal of CoS/CdS heterostructure was specifically activated due to the direct consumption of holes in CdS component by TC, resulting in significantly enhanced charge separation.

Switching the Multiple Function Channels in 2D Hofmann-Type Coordination Polymers.

The modulation of multifunctional molecular materials by utilizing the stimuli-responsive spin crossover (SCO) has attracted considerable research interest due to its potential applications in information storage and smart switching devices. However, the complexity of achieving the integration and interconnection of multiple functions constitutes a formidable challenge.

A mononuclear iron(II) complex constructed using a complementary ligand pair exhibits intrinsic luminescence-spin-crossover coupling.

Molecular materials that exhibit synergistic coupling between luminescence and spin-crossover (SCO) behaviors hold significant promise for applications in molecular sensors and memory devices.

Effects of filter-feeding fish faeces on microbial driving mechanism of lake sediment carbon transformation.

Silver carp (Hypophthalmichthys molitrix) can filter the carbon in the food taken up by phytoplankton and plays an important role in carbon fixation. In this study, the faeces of silver carp, the dominant fish species in Qiandao Lake, China, were collected and subjected to a closed incubation and transformation experiment for three months. The physical and chemical indices of water and sediment mixture, carbon metabolic enzyme activity, and microbial sequences were analyzed to identify the key microbial strains that affect carbon transformation as well as the main factors influencing carbon transformation.

Our previous studies indicated that estrogen-dependent DLBP mechanism was mediated by estrogen receptors (ERs) in the intervertebral disc (IVD) tissue, and the IVD degeneration degree is accompanied by downregulation of ERs, particularly ERβ. However, the neuropathological mechanisms underlying ERs modulation of DLBP are still not well understood.

Criterion of Grouting Pressure in Regional Advance Grouting Treatment to Prevent Water Disaster from Karst Aquifers in Coal Seam Floors.

The deep mining of coal mines in North China faces the serious threat of water inrush from karst aquifers in the coal seam floors, and regional advance grouting technology (RAGT) is an effective means to prevent and control such disasters. However, it is difficult to choose the grouting pressure during the implementation of RAGT, and excessive grouting pressure will lead to the splitting of karst fracture and reduce the grouting effect. In this study, based on the Bernoulli equation, the relationship between the ground grouting pressure and critical grouting pressure during grouting is established.

Clp protease and antisense RNA jointly regulate the global regulator CarD to mediate mycobacterial starvation response.

Under starvation conditions, bacteria tend to slow down their translation rate by reducing rRNA synthesis, but the way they accomplish that may vary in different bacteria. In species, transcription of rRNA is activated by the RNA polymerase (RNAP) accessory transcription factor CarD, which interacts directly with RNAP to stabilize the RNAP-promoter open complex formed on rRNA genes. The functions of CarD have been extensively studied, but the mechanisms that control its expression remain obscure.
