Dual‐Ligand Metal‐Organic Frameworks via In Situ Amidoxime Engineering for Selective Ion Separation

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by microbial ion‐trapping mechanisms, a mild and universal strategy is developed to construct highly porous amidoxime‐functionalized MOFs. DFT calculations and molecular force measurements reveal that the dual‐ligand amidoxime configuration significantly strengthens Ga(III) affinity.

Integrated Routing and Switching Technology for LEO Satellites

open access: yes天地一体化信息网络
Low Earth Orbit (LEO) satellites are capable of delivering more precise and efficient multi-source data fusion information services. This paper delves deep into the impact exerted by the on-orbit characteristics of low-orbit satellites on the ...

Temperature‐Induced Nonvolatile Switching through Thermal Hysteresis in a Gd3Fe5O12/Ho3Fe5O12 Exchange‐Coupled Rare‐Earth Iron Garnet Bilayer

open access: yesAdvanced Functional Materials, EarlyView.
Reducing power consumption in spintronic memory remains a major challenge due to the need for high current densities. A bilayer of gadolinium and holmium iron garnets enables purely temperature‐induced, nonvolatile magnetic switching with bistable states within a ±25 K range. This approach achieves up to 66‐fold lower energy use than current spin–orbit

Nanolayer‐Encapsulated Stretchable Liquid‐Metal Sheets for Thermal Management

open access: yesAdvanced Functional Materials, EarlyView.
A stretchable liquid metal sheet with both high thermal conductivity and mechanical flexibility is developed. Its trilayer structure, comprising copper‐particle‐dispersed gallium liquid metal encapsulated by styrene‐butadiene‐styrene nanosheets, shows 40.4 W m−1 K−1 conductivity, elongation exceeding 200%, and retention of 96% of its initial ...

Indirect Band Edge and Chain‐Locked Linear Dichroism in the Quasi‐1D Van der Waals Antiferromagnet AgCrP2S6

open access: yesAdvanced Functional Materials, EarlyView.
AgCrP2S6 reveals a momentum‐indirect band edge (≈1.35 eV) and chain‐locked linear dichroism: the first direct transitions emerge at 1.6–1.8 eV for E||a. Resonant Raman and photoemission corroborate this assignment. In ACPS/graphene heterostructures, photocurrent turns on above ≈1.5 eV and follows the same polarization selection rules (anisotropy ≈0.53),

Manufacturing the ORBCOMM Constellation Satellites

open access: yes, 1997
Constructing a constellation of thirty-six ORBCOMM LEO digital communications satellites mandates an approach to manufacturing and testing significantly different from other small satellite programs. Schedule constraints forced overlap of development, qualification, and early production phases, and a production rate of four spacecraft per month.
