Purifying membrane proteins has been the limiting step for studying their structure and function. The challenges of the process include the low expression levels in heterologous systems and the requirement for their biochemical stabilization in solution. The human voltage-gated proton channel (hH1) is a good example of that: the published protocols to express and purify hH1 produce low protein quantities at high costs, which is an issue for systematically characterizing its structure and function.

The goal of the present work is to quantify the performance of ozonation as a method for the in situ remediation of soils polluted at varying degree with different types of hydrocarbons, and assess its applicability, in terms of remediation efficiency, cost factors, and environmental impacts. Ozonation tests are conducted on dry soil beds, for three specific cases: sandy soil contaminated with low, moderate and high concentration of a non-aqueous phase liquid (NAPL) consisting of equal concentrations of n-decane, n-dodecane, and n-hexadecane; sandy soil polluted with diesel fuel; oil-drilling cuttings (ODC). The transient changes of the concentration of the total organic carbon (TOC), total petroleum hydrocarbons (TPH), polycyclic aromatic hydrocarbons (PAHs), and soluble chemical oxygen demand (SCOD) in soil and carbon dioxide (CO), carbon monoxide (CO), volatile organic compounds (VOCs), and ozone (O) in exhaust gases are recorded.

Pediatric tuberculosis (TB) is still challenged by several diagnostic bottlenecks, imposing a high TB burden in low- and middle-income countries (LMICs). Diagnostic turnaround time (TAT) and ease of operation to suit resource-limited settings are critical aspects that determine early treatment and influence morbidity and mortality. Based on TAT and ease of operation, this article reviews the evolving landscape of TB diagnostics, from traditional methods like microscopy and culture to cutting-edge molecular techniques and biomarker-based approaches.

The electrochemical cutting technique, utilizing electrolyte flushing through micro-hole arrays in the radial direction of a tube electrode, offers the potential for cost-effective and high-surface-integrity machining of large-thickness, straight-surface structures of difficult-to-cut materials. However, fabricating the array of jet micro-holes on the tube electrode sidewall remains a significant challenge, limiting the broader application of this technology. To enhance the efficiency and quality of machining these jet micro-holes on the tube sidewall, a helical electrode electrochemical drilling method assisted by anode vibration has been proposed.

This study aims to determine the extent to which coating composition and workpiece properties impact machinability and tool selection when turning Compacted Graphite Iron (CGI) under extreme roughing conditions. Two CGI workpieces, differing in pearlite content and graphite nodularity, were machined at a cutting speed of 180 m/min, feed rate of 0.18 mm/rev, and depth of cut of 3 mm.
