Electrochemical stripping analysis (ECSA) is a promising method for metal ions detection. However, the low sensitivity and poor reproducibility limits its practical applications. The combination with other powerful detection techniques to address these concerns is highly desirable. Herein, the anodic stripping method and photoelectrochemical (PEC) technique are integrated into a new detection platform of PEC stripping analysis (PECSA) with bismuth vanadate (BiVO) as both optoelectronic material and an electrochemical enrichment candidate. The new PECSA strategy presents high sensitivity and excellent reproducibility; in addition, inherited from the ECSA, this strategy also offers new selectivity dimensions through the potential-dependent response and thus implements reproducible, sensitive, and selective detection of silver ion (Ag) in real biological and environmental samples. The success of PECAS strategy shed light on the rational combination of various analysis techniques for versatile applications.

Background: The direct and accurate measurement of low-level γ-emitters in samples from nuclear facilities is a challenging task due to the presence of high activities of dominant radionuclides. In this case a complex chemical separation is required to remove interfering radionuclides prior to γ-spectrometric analysis. Several radionuclides such as, Ag, Sb, Sn and Te are of relevance for radioanalytical analysis in nuclear facilities.

Background: Widespread digital transformation necessitates developing digital competencies for public health practice. Given work in 2024 to update Canada's public health core competencies, there are opportunities to consider digital competencies. In our previous research, we identified digital competency and training recommendations within the literature.

Rationale: Peritoneal mucinous cystadenoma is rare in the clinic, lacks specific clinical manifestations, tumor markers, and imaging features, and is easily misdiagnosed and missed. Clinical practitioners should maintain a high level of vigilance. Here, we report a case of laparoscopic peritoneal mucinous cystadenoma stripping to improve our understanding of the disease.

Potassium (K)-based batteries hold great promise for cryogenic applications owing to the small Stokes radius and weak Lewis acidity of K. Nevertheless, energy-dense (>200 W h kg) K batteries under subzero conditions have seldom been reported. Here, an over 400 W h kg K battery is realized at -40 °C via an anode-free and dual-ion strategy, surpassing these state-of-the-art K batteries and even most Li/Na batteries at low temperatures (LTs).
