  • Patent number: 11885979
    Abstract: High-performance optical-metasurface-based components configured to at frequencies of UV light and, in particular, in deep UV range and performing multiple optical-wavefront-shaping functions (among which there are high-numerical-aperture lensing, accelerating beam generation, and hologram projection). As a representative material for such components, hafnium oxide demands creation and establishment of a novel process of manufacture that is nevertheless based on general principles of Damascene lithography, to be compatible with existing technology and yet sufficient for producing high-aspect-ratio features that currently-used materials and processes simply do not deliver. The described invention opens a way towards low-form-factor, multifunctional ultraviolet nanophotonic platforms based on flat optical components and enabling diverse applications including lithography, imaging, spectroscopy, and quantum information processing.

  • Publication number: 20240010774
    Abstract: A solid-phase synthesis carrier, a preparation method therefor and the use thereof, wherein a diene cross-linking agent with a similar reactivity ratio to styrene and two vinyl groups thereof not on the same benzene ring is selected as a cross-linking monomer, and is subjected to suspension polymerization to obtain a porous resin. The porous resin is then functionalized to obtain a porous resin with an amino or hydroxyl functional group. Compared with existing preparation methods, the reactivity ratio of the cross-linking agent and styrene is similar, which is beneficial to improving the uniformity of the chemical structure in the resin, forming uniformly distributed active sites and channels, and is beneficial to improving the reaction efficiency and reducing the mass transfer resistance. The preparation of oligonucleotides by using such a carrier as a solid-phase synthesis carrier can improve the yield and purity of the oligonucleotides.

  • Publication number: 20240004685
    Abstract: Methods and systems for managing virtual machines are described herein. A virtualization computing platform may host a plurality of virtual machines comprising. The platform may detect that the first user device is disconnected from the first virtual machine and determine, using a machine learning model, that the first virtual machine, during a time period while the user device is disconnected, is in an idle state. The platform may obtain, based on the determination that the first virtual machine is in the idle state, a snapshot of the first virtual machine and cease hosting the first virtual machine. If the platform receives a request from a second user device associated with the same user account to continuing using the virtual application executed previously by the first virtual machine, the platform may establish a second virtual machine and load, to memory of the second virtual machine, information associated with the snapshot.
