Mezinárodnímu výzkumnému týmu, jehož součástí byli vědci z&nbsp;Přírodovědecké fakulty Univerzity Palackého a Fyzikálního ústavu Akademie věd ČR, se podařilo objasnit složitý mechanismus tvorby chemické vazby při srážce molekul. Odborníci zjistili, že reakce proběhne pouze tehdy, jsou-li molekuly vůči sobě natočeny ve velmi úzkém rozmezí úhlů – v takzvaném kuželu reakce. Společný výzkum tak přinesl odpověď na jednu ze základních otázek chemie: za jakých podmínek mezi molekulami vznikají chemické vazby. Výsledky studie Spatially resolving the cone of reaction for a single molecule zveřejnil prestižní vědecký časopis Science.Řada chemických reakcí začíná srážkou dvou částic. K vytvoření nové chemické vazby však nestačí, aby se molekuly pouze setkaly. Jejich srážka musí proběhnout s dostatečnou energií, ve vhodné vzájemné orientaci a na správném místě. Za běžných podmínek, například v roztocích nebo plynech, se však molekuly srážejí chaoticky, a přesné parametry těchto srážek proto nelze kontrolovat.<h4>Molekuly pod kontrolou</h4>Vědci na měděném povrchu dokázali řídit srážky jednotlivých molekul a jejich průběh sledovali pomocí rastrovacího tunelovacího mikroskopu. Přístroj využili nejen k zobrazování jednotlivých molekul, ale také k jejich cílenému urychlování reaktantů proti sobě. Každou srážku následně analyzovali s rozlišením na úrovni jednotlivých atomů. Díky tomu mohli jednoznačně určit, zda mezi molekulami vznikla nová chemická vazba.<h5>„To, co je v běžné chemii skryté ve statistice miliard srážek, se nám podařilo rozložit na jednotlivé případy a přímo zmapovat.“ Adam Matěj</h5>Klíčovým zjištěním studie je, že o výsledku srážky rozhoduje mimořádně přesná orientace molekul. Nová vazba vznikla pouze tehdy, když byla cílová molekula natočena v rozmezí několika stupňů vůči směru pohybu druhé molekuly. Při pootočení o více než patnáct stupňů se molekuly pouze odrazily bez jakékoli reakce.<h4>Rozhoduje přesné natočení molekul</h4>„Poprvé jsme mohli u jediné molekuly sledovat, jak přesně musí být natočena, aby reakce vůbec proběhla. To, co je v běžné chemii skryté ve statistice miliard srážek, se nám podařilo rozložit na jednotlivé případy a přímo zmapovat,“ uvedl Adam Matěj z&nbsp;katedry fyzikální chemie přírodovědecké fakulty.Významnou roli ve studii sehrála právě teoretická část, na níž se podíleli vědci z Univerzity Palackého a Fyzikálního ústavu AV ČR. Pomocí kvantově-mechanických výpočtů vysvětlili, proč je „kužel reakce“ tak úzký. Ukázalo se, že reaktivní uhlíkový atom je obklopen atomy vodíku, které brání přístupu reagující molekuly téměř ze všech směrů.<h4>Přístup k reakci omezuje uspořádání atomů</h4>Výpočty zároveň objasnily překvapivý experimentální výsledek. Chemická reakce proběhla i v případě, kdy se molekula pohybovala po sousední řadě atomů mědi, kde by podle původních předpokladů neměla vazba vzniknout.<h5>„Síla této práce je v tom, že se experiment a teorie doplnily do jednoho obrázku. Mikroskop ukázal, co se při srážce stane, a výpočty vysvětlily&nbsp;proč.“ Pavel Jelínek</h5>„Vysvětlením je nepatrný posun jednoho atomu mědi na povrchu. Vazba terče k povrchu ho vytáhne z jeho místa a přiblíží k sousední řadě natolik, že dokáže projektil doslova převzít a nasměrovat na správné místo. Ukazuje to, že povrch není jen pasivní podložka, ale sám aktivně vstupuje do reakce a může umožnit i dráhy, které by jinak byly nepříznivé,“ podotkl Adam Matěj.<h4>O průběhu reakce rozhoduje i povrch</h4>Výsledky mají význam pro vývoj takzvaných reakcí na površích, při nichž se z jednotlivých molekul cíleně skládají nové materiály a nanostruktury. Lepší pochopení vlivu prostorového uspořádání molekul umožní navrhovat molekulární stavební kameny tak, aby se spojovaly spolehlivěji a efektivněji. To představuje důležitý krok pro vývoj technologií založených na řízené stavbě struktur atom po atomu.„Síla této práce je v tom, že se experiment a teorie doplnily do jednoho obrázku. Mikroskop ukázal, co se při srážce stane, a výpočty vysvětlily&nbsp;proč. Bez teoretického modelu bychom jen těžko odhalili, že za nečekaným průběhem reakce stojí pohyb jediného atomu povrchu,“ doplnil Pavel Jelínek z Fyzikálního ústavu Akademie věd ČR.<blockquote>Studie Spatially resolving the cone of reaction for a single molecule vznikla ve spolupráci vědců z Univerzity v Grazu, Fyzikálního ústavu Akademie věd ČR, Univerzity Palackého v Olomouci, Univerzity Karlovy a Humboldtovy univerzity v Berlíně.</blockquote>

Water quality is critical across many applications, including drinking water, beverage manufacturing, and wastewater. In food and beverage environments, contaminants can affect organoleptic properties, such as taste and appearance, as well as the overall safety of the water.A wide range of analytes can impact water quality, including nitrate content, and multiple methods available to assess the concentration of these components. UV-Visible spectrophotometry is one such technique, enabling the quantification of many analytes that influence water quality. As Beer’s law indicates, measured absorbance in the UV-Visible range is directly proportional to concentration, making the technique particularly useful when assessing analyte concentration.In many analyses, colorimetric reagents as required to produce a measurable absorbance in this spectral range. A standard curve is then typically developed using known standards to correlate the measured absorbance with the concentration of the analyte.In this webinar, attendees will discover how instruments such as Thermo Scientific GENESYS G5 UV-Visible spectrophotometers can support the assessment of water samples from a variety of sources.<h4>You’ll learn:</h4><ul><li>Explore different environments where water analysis can be important.</li><li>Learn how UV-Visible spectrophotometry can be used to determine the concentration of various analytes commonly assessed in water applications.</li><li>Understand best practices for using pre-built standard curves and creating new curves when determining analyte content in water sources.</li></ul><blockquote>Presenter: Jennifer Empey-Kohl (Applications Scientist, Thermo Fisher Scientific)Jennifer Empey-Kohl has been with Thermo Fisher Scientific as an Applications Scientist for 5 years where she supports the cuvette-based UV-Visible instruments.

Renewable energy resources such as solar are promising complements to the combustion of fossil fuels. However, the intermittent and diurnal nature of sunlight necessitates economical and efficient energy storage technologies. A promising approach to both storing solar energy and generating combustible liquid fuels is driving the transformation of abundant energy-poor feedstocks (CO2, H2O) into energy-dense liquid fuels using energy from solar photons, known as “artificial photosynthesis.”&nbsp;One approach for artificial photosynthesis is to immobilize fuel-producing molecular catalysts onto light-absorbing semiconductor materials to create “hybrid photoelectrodes,” allowing for both the stability of heterogenous surfaces and the tunability of molecular catalysts. The Center for Hybrid Approaches in Solar Energy to Liquid Fuels (CHASE) is a multi-institutional energy innovation hub which aims to advance hybrid photoelectrodes for the light-driven generation of liquid fuels from CO2 and H2O. A variety of chemical techniques, including sonochemical hydrosilylation, π-π stacking, and electrochemical grafting, are utilized to anchor ruthenium and rhenium molecular CO2-reduction catalysts to a silicon surface.&nbsp;To study the efficacy of these catalyst loading techniques, Inductively Coupled Plasma Mass Spectrometry (employing an Agilent 7850 ICP-MS) is leveraged to quantify catalyst surface coverage. Silicon samples are digested in an HNO3/HCl matrix to solubilize ruthenium and rhenium metal centers. As each anchored molecular catalyst contains one metal center, surface coverage estimates can be drawn by pairing ICP-MS data with the dimensions of the catalyst and the size of the silicon photoelectrode. From these data, key conclusions are drawn which correlate anchoring technique, reaction time, and silicon morphology to the loadings of these molecular catalysts. This information provides a guiding framework for next-generation designs of hybrid photoelectrodes.<blockquote>Presenter: Jillian L.

Laboratories are under growing pressure to handle increasing volumes of samples and data while operating under tighter regulatory inspection, all without compromising turnaround times or traceability. In this context, many organizations attempt to extend existing workflows and legacy tools, which can introduce inefficiencies, increase manual effort, and create compliance risks. At the same time, it is not always clear which digital solutions are best suited to address these challenges.This presentation illustrates how modern digital laboratory environments streamline routine activities by minimizing manual tasks and embedding compliance directly into everyday workflows. Drawing on a real-world use case, we show how automated capture of data from multiple sample measurements at the point of execution enables a continuous, sample-centric workflow.By removing manual interventions and paper-based processes, laboratories can improve efficiency and visibility, support faster and more reliable decision-making while remaining responsive to evolving customer demands.<h4>Learning Points</h4><ul><li>The role of different systems (LIMS, SDMS, ELN) within the digital lab landscape and how they differ from each other's</li><li>How WebLab manages laboratory operations from a sample perspective, enabling you to track every sample, stage, and next action across workflows</li><li>How automated data capture from connected instruments helps reduce errors, lower contamination risks, and accelerate sample processing</li><li>You will see, through a real-life example, how integrated digital workflows improve data quality, accelerate reporting, and increase operational efficiency</li></ul><h4>Who should attend</h4>Professionals working in small to mid‑sized laboratories, including:<ul><li>Directors and Managers of Analytical, QC, or Contract Labs</li><li>Lab Operations and QA/QC Leaders</li><li>Digitalization and IT at organizations transitioning from paper, Excel, or legacy systems to LIMS</li></ul><blockquote>Presenter: Peter Bellstedt, PhD (Director of Business Development and Product Manager at SciY)Peter studied Biochemistry at the University of Jena before completing a PhD on the structural characterization of a DNA repair protein using solution and solid-state NMR.

An accessory to make absolute specular measurements for specific angles has been available for decades. It's limitation is that it is not easily adaptable to measuring absolute reflectance at any given angle. The Cary 7000 with its unique accessory design has changed the difficulty of the measurement from being a limitation to one of ease. Adding the desire to measure both reflectance and transmission at the same angle increases the design problem which previously was dealt with by using two accessories, one for reflectance and one for transmission. This approach led to uncertainties in knowing the measurements were being made on the same spot. This presentation will look at the design of an absolute reflectance accessory along with the ease of use to be able to collect absolute specular measurements at nearly any user desired angles.<blockquote>Presenter: Scott Melis, PhD (Application Scientist, Agilent Technologies, Inc.)Scott Melis has a PHD in Physics from Georgetown University in Washington, DC and started with Agilent in 2021 as a Molecular Spectroscopy Application Scientist. In his graduate work, Scott studied nanoparticle formation and growth for a variety of applications. Projects that he worked with include developing processes to deposit and characterize semiconducting molecular nano-cocrystals for use in optoelectronic devices as well as controlling polymer nanoparticle size through rapid mixing conditions.</blockquote>

Understanding the tissue microenvironment in tumour samples is an important factor for predicting response to different treatment regimens. Highly multiplexed imaging of tenfolds of protein markers can help to define this complex biology. However, these assays are costly and not always easy to scale for larger translational studies that are often needed to translate findings to clinical evidence.&nbsp;In this webinar, we demonstrate how we move from a highly multiplexed imaging platform used in a discovery phase to identify a marker for response prediction to immunotherapy at the translational phase. This transition was possible with the use of the Invitrogen™ EVOS™ S1000 Spatial Imaging System in combination with the Invitrogen™ Aluora™ Spatial Amplification Kits and a panel of 6 markers. By focusing on the most relevant targets from the discovery panel, the cost per sample is reduced to about 25 % of the initial assay, thereby resulting in a more affordable option for larger translational cohort studies. In addition, we show how relevant protein markers can be combined with in situ proximity Ligation Assay (is PLA) to simultaneously look at protein interactions, in this case demonstrated for PD-1/PD-L1. In summary, this workflow enables scalable, cost-effective spatial biology approaches that bridge discovery and clinical translation.&nbsp;<h4>Learning Objectives:</h4><ul><li>Learn how to transition from discovery to translational proteomic imaging assays&nbsp;</li><li>Understand how spectral imaging with the EVOS S1000 Spatial Imaging System can be used for hypothesis-driven research</li><li>Explore the use of spatial amplification reagents for exploring the tissue microenvironment</li></ul><blockquote>Presenter: Charlotte Stadler, PhD (Co-director of Spatial Biology and Head of the National Spatial Proteomics facility at Science for Life Laboratory)Charlotte Stadler is the co-director of the Spatial Biology platform and Head of the National Spatial Proteomics facility at Science for Life Laboratory.
