Artificial intelligence sheds light on membrane performance


Membrane separations have long been recognized as energy-efficient processes with a rapidly growing market. In particular, organic solvent nanofiltration (OSN) technology has shown considerable potential when applied to various industries, such as petrochemicals, pharmaceuticals and natural products. The energy consumed by these industries accounts for 10 to 15 percent of the world's entire energy consumption. Nevertheless, difficulties in predicting the separation performance of OSN membranes have hindered smooth transition from lab discovery to industry implementation. Predicting the performance of membranes is a challenging task because of the complex nature of solvent, solute and membrane interactions.

When heat is applied to these products, a tight seal is formed on polypropylene, polyethylene, polystyrene, polycarbonate, and cyclin olefin copolymer (COC) microplates and tubes. Optically clear films from Porvair are available in a variety of formats, including peelable, pierceable, and strong nonpeelable. These seals are ideal for a wide range of applications, such as imaging, fluorescence, colorimetric assays, and PCR/quantitative PCR. All clear seals are also compatible with devices that use a heat-pressurized lid. The Dura range of durable, foil-based heat-sealing films are ideal for high-temperature applications and room-temperature storage. They come in a variety of formats, including peelable, solvent resistant (including DMSO) and pierceable. All Dura heat-sealing films are autoclavable. Absolute Antibody Ltd., along with the University of Zurich, now offers synthetic nanobodies against the receptor binding domain of SARS-CoV-2, the coronavirus that causes COVID-19. Researchers are exploring the potential of nanobodies as inhalable COVID-19 drugs, which would be easier to administer and could reach patients' lungs faster than other treatments. Absolute Antibody recombinantly produces the SARS-CoV-2 synthetic nanobodies for ensured batch-to-batch reproducibility, high purity, and low endotoxin levels. In addition, we use antibody engineering to fuse the nanobodies to fragment crystallizable (Fc) domains in different species, isotypes, and subtypes for use as serological controls. CELLvo Human Articular Chondrocytes from StemBioSys are low-passage (P0 and P1) cells freshly isolated from young, healthy donors and available for regenerative medicine and basic research. When cultured with CELLvo Matrix, the cells home, attach, and proliferate more rapidly than chondrocytes cultured under standard conditions. They also exhibit similar morphology and phenotype to in vivo chondrocytes, such as a high ratio of type 2 collagen to type 1 collagen. Because the cells and the growth conditions are never exposed to nonhuman proteins, they offer a streamlined pathway to clinical studies. The CELLvo Human Chondrocyte cell culture system delivers improved performance and exceptional research potential to basic and translational studies of osteoarthritis, joint function, chondrocyte differentiation, tissue engineering, and chondrocyte implantation. The FlowSyn Automated Loop Filling (FlowSyn Auto-LF) system is a powerful, highly efficient module for running multiple experiments with multiple reagent inputs under different sets of chemical conditions. This product is ideal for robotic synthesis groups looking to generate combinatorial libraries utilizing the power of flow chemistry. With a choice of two or four channels, this intelligent, simultaneous loop-filling and fraction-collection system saves valuable time by loading the reagent loops for the next reaction while the current run is in progress. Fully integrated wash protocols minimize the risk of cross-contamination. The unit incorporates an automated liquid handler that can accommodate up to 96 samples. The BioTek LogPhase 600 Microbiology Reader is the only four-plate microplate reader built to perform microbial growth curve analysis. Multiple plate measurements increase throughput and reduce the need for costly single-plate absorbance readers that take up valuable bench space. Additionally, highly consistent environmental conditions support high-quality absorbance results without growth curve artifacts, even in bacterial and yeast assays with extended incubation periods. The compact LogPhase 600 features a robust, stringently tested shaking mechanism to ensure that cells remain in suspension and that the hardware will not wear out, even over the course of long-term kinetic assays. Incubation is controlled by several sensors for even heating and includes Condensation Control, which prevents light scatter and artifacts due to condensation. The LogPhase 600 App controls the reader, capturing data and providing powerful analysis with an easy-to-use interface. This reader is ideal for yeast and bacterial growth assays, antimicrobial resistance studies, algal and biofuel research, and food and beverage testing. The T-SPOT Discovery SARS-CoV-2 kit from Oxford Immunotec has been developed to aid in the investigation of the T-cell response to SARS-CoV-2 infection. The kit uses a modified enzyme-linked immunospot (ELISPOT) assay, where samples prepared from peripheral blood are stimulated in vitro by peptide pools from SARS-CoV-2. This restimulation allows SARS-CoV-2–specific T cells to be enumerated. The kit builds on our experience with tuberculosis diagnosis and the assessment of immune response to cytomegalovirus in transplant patients to apply our proprietary T-SPOT technology to the fight against COVID-19. While serology is able to detect antibodies to SARS-CoV-2 in the blood of some individuals after infection, little is currently known about how this confers immunity to COVID-19. The T-SPOT technology goes further than simple serology by interrogating the immune system's T-cell response, and will help researchers measure the strength of that response to SARS-CoV-2. The strength of this response may be linked to protection from reinfection. [1]: pending:yes

How Machine Learning (ML) Can Transform The Chemical Industry


Machine learning and AI can improve the functionalities of the chemical industry through the identification of chemical molecules -reactiveness and toxicity level during process engineering. And it can also be used to check the availability of raw materials, feasibility of compound, measuring blending temperature of certain chemical, and environmental concerns during production, transportation, and storage. And in the future, it is expected to increase the speed of the production process through ML technologies at its core. The industries interdependent on the chemical industry like agriculture, construction, automotive, cosmetics, energy, consumer products, transportation, etc., are implementing technology at their core; and the development of these industries will increase the growth of the chemical industry. Hence, the RoI on machine learning goes beyond the product revenue and chemical process.

Scope and Impact of AI in Agriculture - KDnuggets


The Green Revolution during the 1950s and 1960s remarkably drove up the global food production around the world, saving a billion people from starvation. The revolution led to the adoption of new technologies like high-yielding varieties (HYVs) of cereals, chemical fertilizers and agro-chemicals, better irrigation and mechanization of cultivation methods. India followed suite and adopted the use of hybrid seeds, machine, fertilisers and pesticides. While these practices solved the food shortage problem, they created some problems too in terms of excessive use of fertilisers and pesticides, depletion of ground-water, soil degradation etc. These problems were exacerbated by lack of training to use modern technology and awareness about the correct usage of chemicals etc.

Robot scientist discovers a new catalyst


Researchers at the University of Liverpool have built an intelligent, mobile, robotic scientist that can solve a range of research problems. The robot seen here can work almost 24-7, carrying out experiments by itself. The automated scientist – the first of its kind – can make its own decisions about which chemistry experiments to perform next, and has already discovered a new catalyst. With humanoid dimensions, and working in a standard laboratory, it uses instruments much like a human does. Unlike a real person, however, this 400 kg robot has infinite patience, and works for 21.5 hours each day, pausing only to recharge its battery.

Temperature-resilient solid-state organic artificial synapses for neuromorphic computing


Devices with tunable resistance are highly sought after for neuromorphic computing. Conventional resistive memories, however, suffer from nonlinear and asymmetric resistance tuning and excessive write noise, degrading artificial neural network (ANN) accelerator performance. Emerging electrochemical random-access memories (ECRAMs) display write linearity, which enables substantially faster ANN training by array programing in parallel. However, state-of-the-art ECRAMs have not yet demonstrated stable and efficient operation at temperatures required for packaged electronic devices (~90°C). Here, we show that (semi)conducting polymers combined with ion gel electrolyte films enable solid-state ECRAMs with stable and nearly temperature-independent operation up to 90°C. These ECRAMs show linear resistance tuning over a >2× dynamic range, 20-nanosecond switching, submicrosecond write-read cycling, low noise, and low-voltage (±1 volt) and low-energy (~80 femtojoules per write) operation combined with excellent endurance (>109 write-read operations at 90°C). Demonstration of these high-performance ECRAMs is a fundamental step toward their implementation in hardware ANNs.

Boston Dynamics' robot dog inspects SpaceX site in Texas

Daily Mail - Science & tech

Footage has emerged of one of Boston Dynamics' robotic dogs patrolling a SpaceX test site in the US. The video allegedly shows SpaceX using the $75,000 (£60,000) robotic dog to inspect the aftermath of its test site in Boca Chica, Texas. SpaceX had just been conducting a cryogenic pressure test on the Starship SN7 dome tank prototype, according to Tesmanian. SN7 was filled with sub-cooled liquid nitrogen and it was intentionally pressurised to its capacity before it burst and collapsed on its side. The stainless-steel commercial spacecraft, once operational, will be capable of transporting passengers on long-duration voyages to the Moon and Mars. But until the launch vehicle is ready, Elon Musk's company appears to be employing a little help from a trusty robotic companion.
