Starches, a storage form of carbohydrates, are major source calories in the human diet and primary feedstock for bioindustry. We report chemical-biochemical hybrid pathway starch synthesis from carbon dioxide (CO2) hydrogen cell-free system. The artificial anabolic (ASAP), consisting 11 core reactions, was drafted by computational design, established through modular assembly substitution, optimized protein engineering three bottleneck-associated enzymes. In chemoenzymatic system with spatial...

A wide range of polynitrogen species have attracted much attention because their potential applications as high-energy-density materials. Until now, predicted was found to be negatively charged, with charge transfer from introduced atoms nitrogen in nitrogen-bearing compounds. Using an evolutionary algorithm combined first-principles calculations, stoichiometries and structures nitrogen–fluorine compounds at pressures ranging 0 200 GPa are investigated. In addition two fluorine-rich NF3 NF5,...
The properties of cg-N with point defects and an interface are investigated based on the first-principles method. Our results show that at 0 GPa, stability cavities depends their size. A smaller cavity has higher than larger case. decomposition N2 molecules mainly occurs (110) surface cavity. However, process will be suppressed by applying high-pressure. For constructed surfaces, released low pressure, polymerization surfaces is triggered loading pressures 80–100 Gpa, giving rise to a stable...
Compared to the currently widely used propane dehydrogenation process for propylene production, oxidative (ODHP) offers advantage of no thermodynamic limitations and lower energy consumption. However, a major challenge in ODHP is occurrence undesired over-oxidation reactions propylene, which reduce selectivity hinder industrialization. MOFs possess large number metal sites that can serve as catalytic centers, facilitates easier access reactants centers reaction. Additionally, their flexible...
Abstract Global climate deterioration intensifies the demand for exploiting efficient CO 2 utilization approaches. Converting to biorefinery feedstock affords an alternative strategy third‐generation biorefineries. However, upcycling into complex chiral carbohydrates remains a major challenge. Previous attempts at sugar synthesis from either produce mixtures with poor stereoselectivity or require ATP as cofactor. Here, by redesigning glycolaldehyde synthase, authors constructed synthetic...
Black-phosphorus-structured nitrogen (BP–N) is an attractive high-energy-density material. However, high-pressure-synthesized BP-N will decompose at low pressure and cannot be quenched to ambient conditions. Finding a method stabilize it 0 GPa of great significance for its practical applications. unlike cubic gauche, layered polymeric, hexagonal polymeric (cg-N, LP-N, HLP-N), always metastable phase high pressures up 260 GPa, decomposes into chains 23 GPa. Here, on the basis first-principles...
The polymerization of nitrogen can be used as high energy density materials. crystal structures Li2N2 at pressures are explored by using the first-principles method combined with evolutionary algorithm. phase transitions Pmmm → Immm Pnma Cmcm-1 I41/acd predicted in pressure range 0-300 GPa. Enthalpy calculations reveal that tetragonal containing spiral chains is stable above 242 GPa, indicating realized under pressure.
We design and implement a satellite optical switching hardware platform based on burst (OBS) technology. The runs stably realizes 20*20 channels of Microseconds level switching, which meets the requirements quality service (QoS) in current network.
Superionic ice with oxygen in a face-centered cubic (fcc) sublattice is ascribed to the origin of magnetic fields Uranus and Neptune, since melting temperature (Tm) fcc-superionic believed be higher than isentropes giants. However, precisely measuring phase experimentally remains difficult task. The majority systematic investigations its Tm were performed using perfect fcc-sublattice computations, which could result superheating overestimation Tm. On basis ab initio molecular dynamics method...
The structural, electronic, and magnetic properties of MnF2 under high pressure temperature are investigated based on the first-principles methods combined with quasi-harmonic approximation structure-search method. obtained results using different exchange-correlation functionals lead to a band gap between 7.3 10 eV for rutile-type MnF2. varies very slightly pressure, giving rise comparable coefficients reported materials smallest coefficient, such as diamond SiC. At room temperature,...
High speed Ethernet traffic is important for some system tests which use TCP/IP as the data communication. A software way to do this job brings benefits on robust, but due limitation of CPU, it can not give full line frame, especially where short frame needed. An implementation an embedded high network generator based FPGA introduced. It be used generate arbitrary length PRBS frame. Due process ability FPGA, even when 64 bytes, almost theoretical value, 10 times fast than method.
