Various investigators have reported that relapses after healing of duodenal ulcers with colloidal bismuth subcitrate (CBS, De-Nol) occur less frequently than after healing with H2-antagonists. To date, treatment with CBS has been limited to 8 weeks. After a volunteer study showed that prolonged administration of CBS did not cause safety problems, a trial was undertaken in which the effects of additional maintenance CBS treatment with 120 mg of CBS daily is compared with placebo. Interim results showed that after 6 months endoscopically confirmed relapse occurred in 5 (38.5%) of the 13 patients as compared to 12 (80%) of the 15 placebo-treated patients (p = 0.05). Besides 3 cases of transient constipation, no side effects, neurological, biochemical or hematological changes were observed.

Applicable to convert soluble U(VI) into the less mobile U(IV) form, the photocatalytic process is widely regarded as an efficient solution to uranium pollution. In the present study, BiOI/g-CN (BICN) composites were produced through uncomplicated hydrothermal synthesis, followed by U(VI) photocatalytic reduction. Batch experiments were conducted to demonstrate the exceptional capability of BICN to address uranium contamination.

Triethylamine, an extensively used material in industrial organic synthesis, is hazardous to the human respiratory and nervous systems, but its accurate detection and prediction has been a long-standing challenge. Herein, a machine learning-motivated chemiresistive sensor that can predict ppm-level triethylamine is designed. The zero-dimensional (0D) bismuth vanadate (BiVO) nanoparticles were anchored on the surface of three-dimensional (3D) tungsten oxide (WO) architectures to form hierarchical BiVO/WO heterostructures, which demonstrates remarkable triethylamine-sensing performance such as high response of 21 (4 times higher than pristine WO) at optimal temperature of 190 °C, low detection limit of 57 ppb, long-term stability, reproducibility and good anti-interference property.

The photocatalytic degradation (PCD) of toluene (as model aromatic volatile organic compound (VOC)) is studied using two-dimensional semiconductors (bismuth oxyhalides (BiOX (X = Cl and Br)) synthesized with surface defects (BiOX-R (R = reduction)) through a solvothermal-induced reduction process. The PCD efficiency of BiOCl-R against 5 ppm toluene (20 % relative humidity (RH)) is 98.6 % under ultraviolet light irradiation with the quantum yield and clean air delivery rate of 1.

Pollution of microplastics (MPs) has been drastically threating human health, however, whose elimination from the environment by current approaches is inefficient due to their high molecular weight, stronghydrophobicity and stable covalent bonds. Herein, we report a novel and highly-efficient route to degrade MPs contaminants through synergistically piezocatalytic and Fenton-like activation of HO by a ferroelectric Bi(BiFe)O catalyst under ultrasound treatment. For 10 g/L polyethylene terephthalate microplastics (PET-MPs), the synergistic strategy reached a 28.
