Czech researchers from Charles University, Prague, led by Pavla Eliášová, have developed an advanced photocathode that helps convert the greenhouse gas carbon dioxide into pure ethanol using sunlight. The new technology solves a long-standing problem of material degradation in water, achieves record conversion efficiency, and opens the way toward sustainable production of green fuels.Converting carbon dioxide (CO2) into useful fuels using solar energy represents the holy grail of modern green chemistry. The device enabling this conversion is called a solar reactor. Its key element is a photocathode: a material that absorbs light and enables the chemical reaction. Cuprous oxide long appeared to be an ideal material because it is inexpensive, readily available, and excels at capturing solar rays. In practice, however, it faced a fundamental obstacle: in an aqueous environment under light, it transforms and degrades extremely rapidly—much like iron undergoing swift corrosion—and loses its functionality within just tens of minutes.The team from the Chemistry Section of the Faculty of Science, CU, led by Pavla Eliášová, in collaboration with Tomáš Hrbek from the Faculty of Mathematics and Physics, CU, resolved this issue by creating a unique "nano-sandwich". The scientists combined cuprous oxide with advanced two-dimensional materials called MXenes and, through precisely controlled heating, created an ultrathin layer of titanium dioxide on their surface. MXene modified in this way can rapidly drain electric charge from the cuprous oxide, thereby slowing down its decomposition. At the same time, it uses the charge further to convert carbon dioxide into liquid fuel."Surface-engineered MXene combined with cuprous oxide allowed us to unite the best of both materials. The copper base enables maximum utilization of light energy, while the conductive MXene framework ensures that the material remains active even after many hours of operation," explains research team leader Pavla Eliášová from the Chemistry Section of the Faculty of Science, Charles University.In laboratory tests, the new photocathode achieved a record solar-energy-to-ethanol conversion efficiency of 2,74 %. A crucial improvement is the formation of only a single product. While other systems often produce a mixture of byproducts, the material designed by the research team produces pure ethanol as its sole liquid product, which significantly simplifies its potential industrial application."This is a major step forward for us. On our laboratory scale, the system works very well and produces ethanol over many hours. In the next step, we want to further reinforce the stability of the entire photocathode and begin testing on a larger scale and under real daylight conditions," adds physical chemist Pavla Eliášová.The research was conducted within the international European project DESIRED (Horizon Europe), with support from the Charles University Research Centre (UNCE) and the L'Oréal-UNESCO For Women in Science program.<blockquote><h4>Article</h4><h4><a target="_blank" rel="noopener noreferrer" href="https://advanced.onlinelibrary.wiley.com/doi/10.1002/aenm.71469">Surface-Engineered Ti3C2Tx MXene/Cu2O Photocathodes for Highly Selective Photoelectrocatalytic CO2 Reduction to Ethanol</a></h4>Luis A.

While its low bandgap enables photoexcitation by visible light, long-term stability remains limited due to quick charge recombination and photocorrosion. Here, we enhanced charge separation and extraction by combining Cu2O with surface-engineered MXenes. In this novel architecture, TiO2 grows in situ on the surface of Ti3C2Tx and serves as a charge-transport layer, forming a junction with Cu2O. On the other side, the outer TiO2 surface exposed to the CO2-saturated electrolyte offers catalytically active sites for CO2 reduction. Acting as a central layer, the MXene conductive backbone provides an electronically continuous pathway for electron transport. In PEC CO2RR, the photocathode containing 50 wt.% of MXene and a balanced amount of TiO2 on the Ti3C2 surface outperformed the best Cu/CuxO-based systems operating in non-organic electrolytes reported in the literature. The FTO/Cu2O/ml-Ti3C2Tx-350-N2 photocathode reached 8.4&nbsp;µmol&nbsp;cm−2 h−1 ethanol production rate and 2.74% solar-to-ethanol efficiency after 2&nbsp;h. Moreover, pairing TiO2-MXene with Cu2O significantly stabilized the photocathode, which maintained 76% of the ethanol production rate after 6 h. Overall, our results establish surface-engineered Cu2O/TiO2-MXene heterostructures as a solid platform for highly selective, visible-light-driven ethanol production with significantly improved operational stability.

Gas chromatography (GC) is an analytical technique used to separate and analyze compounds that can be vaporized without decomposition. In forensic science, GC is invaluable for identifying and quantifying substances present in various types of evidence.Gas chromatography offers several advantages that make it indispensable in forensic science:<ul><li>GC can detect and identify minute quantities of substances, even at trace levels, allowing forensic scientists to analyze small samples effectively.</li><li>It is capable of analyzing a wide range of volatile and semi-volatile compounds, making it suitable for various types of forensic evidence, including drugs, explosives, and environmental samples.</li><li>GC provides precise measurements of compound concentrations, which is essential for determining levels of substances such as blood alcohol content or drug quantities in forensic toxicology reports.</li><li>It can quickly separate and analyze compounds, enabling timely processing of forensic evidence, which is crucial in criminal investigations.</li><li>Combining GC with mass spectrometry enhances the ability to identify compounds with high accuracy, even in complex mixtures, by providing both separation and molecular identification.</li></ul>These advantages make gas chromatography a powerful tool in forensic investigations, aiding in the accurate detection and analysis of chemical substances found at crime scenes.<h4>How Gas Chromatography Works?</h4>In simple terms, gas chromatography involves the following steps:<ul><li>Sample Introduction: A small amount of the sample is injected into the chromatograph.</li><li>Vaporization: The sample is heated and vaporized.</li><li>Carrier Gas: An inert gas, such as helium or nitrogen, carries the vaporized sample through a column containing a stationary phase.</li><li>Separation: As the sample moves through the column, its components interact differently with the stationary phase, causing them to separate based on their chemical properties.</li><li>Detection: Separated compounds exit the column and are detected, producing a chromatogram - a visual output that displays the presence and quantity of each component.</li></ul><h4>Applications of Gas Chromatography in Forensics</h4>GC is an important l tool in forensic science, offering a wide range of applications that aid in the investigation and resolution of criminal cases. Here are some of the key applications:<h5>Drug Analysis and Toxicology</h5><ul><li>Drug Detection: GC is used to identify and quantify drugs in biological samples such as blood, urine, or hair. This helps determine if a suspect was under the influence during a crime and aids in postmortem toxicology to establish the cause of death.</li><li>Toxicology: GC helps detect toxic substances like poisons, which is vital for determining the cause of death and intent in criminal cases.</li></ul><h5>Arson Investigations</h5>GC is used to analyze fire debris for accelerant residues, helping investigators determine the cause of fires and identify potential arson.<h5>Crime Scene Analysis</h5>GC can analyze samples from crime scenes, such as blood or fibers, to identify substances and potentially link suspects to the scene.<h5>Forensic Pathology</h5>GC helps analyze bodily fluids to determine if alcohol, drugs, or poisons were present at the time of death, aiding in pathology conclusions.Forensic laboratories utilize advanced <a target="_blank" rel="noopener noreferrer" href="https://www.phenomenex.com/industries/forensic-toxicology">forensic toxicology solutions</a> to detect and analyze toxins and drugs in biological samples. Among these, <a target="_blank" rel="noopener noreferrer" href="https://www.phenomenex.com/techniques/gc">gas chromatography techniques</a> are essential for separating and identifying volatile compounds in complex mixtures, enhancing the accuracy of toxicological analyses.<h4>Challenges of Using GC in Forensics</h4>Despite its advantages, there are several challenges and considerations that forensic scientists must address when using GC in their investigations.<ul><li>One of the primary limitations of GC is the coelution of compounds, where multiple substances elute from the column at the same time, making it difficult to separate, identify and quantity them correctly.</li><li>GC requires careful sample preparation, including extraction and cleanup procedures, which can be time-consuming and require specialized equipment and expertise. This complexity can delay analysis and increase costs.</li><li>GC is primarily suited for the analysis of volatile and semi-volatile organic compounds. It is not suitable for many types of inorganic compounds or biopolymers, limiting its applicability in certain forensic contexts.</li><li>The presence of certain compounds in the sample can interfere with the accuracy of GC analysis, leading to false positives or false negatives. Additionally, matrix effects can affect the reliability of the results, requiring careful sample preparation and the use of internal standards to minimize these issues.</li></ul><h4>Important Factors to Consider When Using GC for Forensics</h4><ul><li>Ensuring that GC instruments are properly calibrated and validated is crucial for obtaining reliable results. Regular maintenance and quality control measures are essential to prevent instrument drift and ensure consistency in analysis. Specialized <a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/en-us/all/products?category=7&amp;manufacturerItems=50">gas chromatography</a> products are employed, ensuring precise and reliable results in forensic investigations.</li><li>The interpretation of GC data requires expertise, as the chromatograms can be complex, especially in cases involving mixtures of substances. Experienced analysts are needed to accurately identify and quantify components.</li><li>Forensic GC analyses must comply with legal standards and regulations. This includes adhering to specific protocols for sample handling, analysis, and reporting to ensure that evidence is admissible in court.</li><li>Combining GC with other analytical techniques, such as mass spectrometry (MS), can enhance its capabilities. For example, GC-MS is widely used in forensic analysis due to its ability to provide detailed information about the molecular weight and elemental composition of compounds.</li></ul>By understanding these challenges and considerations, forensic scientists can effectively utilize GC to analyze evidence.

XRF for Elemental Analysis of Accelerated Drugs

The compound that binds best isn't always the one that works. Compounds with similar affinity and kinetics often behave very differently downstream — because binding alone doesn't reveal how a molecule reshapes its target.Join us for this live webinar unveiling Molecular Friction Sensing on heliX⁺, a newly published approach for detecting ligand-induced conformational changes in proteins with sub-Ångström resolution under near-physiological conditions. Binding-induced modulation of protein structure is central to how many small-molecule drugs work, yet most screening platforms rely on affinity-based readouts that don't report conformational change. By resolving structural effects independently of affinity or kinetics, Molecular Friction Sensing adds an orthogonal decision-making dimension to hit-to-lead and lead optimization, helping you prioritize the most promising candidates earlier.Presenting the science behind the recently released preprint, this session shows how the assay works, what it reveals, and how it fits alongside your existing biophysical toolkit.<h5>What you'll learn</h5><ul><li>How Molecular Friction Sensing detects ligand-induced conformational changes at sub-Ångström sensitivity</li><li>Why a conformational readout adds information that affinity and kinetic data don't capture</li><li>How to tell apart binders with similar affinities by their effect on protein structure</li><li>Where the assay fits between routine binding assays and classical structural biology</li><li>Results from the preprint, including the characterization of 22 confirmed carbonic anhydrase binders</li></ul><blockquote>Speaker: Prof. Dr. Ulrich Rant (Dresden University of Technology, Kurt Schwabe Institute for Sensor Technologies, Bruker Dynamic Biosensors, Dresden, Germany)</blockquote>
