Advanced Porous Materials for Maritime Carbon Capture
Advanced Materials, EarlyView.Carbon capture from emission sources, such as marine vessels, has attracted significant attention over the years. To achieve this goal, sorbents such as metal–organic frameworks (MOFs), porous polymer networks (PPNs), covalent organic frameworks (COFs), and their post‐synthetic modifications are currently being explored.

Demonstration of a sterilizable solid rocket motor system [PDF]
A solid propellant rocket motor containing 60.9 Kg (134-lb) of propellant was successfully static fired after being subjected to eight heat sterilization cycles (three 54-hour cycles plus five 40-hour cycles) at 125 C (257 F).

Heat exchanger for electrothermal devices [PDF]
, 1986 An improved electrothermal device is disclosed. An electrothermal thruster utilizes a generally cylindrical heat exchanger chamber to convert electricity to heat which raises the propellant temperature.

Recent Advances in Collective Behaviors of Micro/Nanomotor Swarms
Advanced Materials, EarlyView.This review describes the driving forces behind collective motion, explores the self‐organization of micro/nano swarms across zero‐dimensional (0D), one‐dimensional (1D), two‐dimensional (2D), and three‐dimensional (3D) spaces, and highlights their potential in drug delivery, environmental monitoring, and smart devices.

Volumetric calibration of a propellant utilization system [PDF]
, 1970 Method of calibrating capacitance-type propellant mass sensors provides meaningful mass units accurate to within one percent of the total load. Neither special propellant loading nor test firing is required.

Advanced Materials, EarlyView.All‐perovskite tandem solar cells are evaluated under low‐intensity and low‐temperature (LILT) conditions relevant to space environments. Distinct loss regimes emerge, where weaker entropic mixing causes halide segragation below ≈240 K going along with a strong current imbalance, while poor electron transport in C60 dominates.

Entry reaction control system propellant analysis. Flight control integration [PDF]
The effects of winds, sideslip angle feedback, and the data reference (air or inertial) on the Reaction Control System (RCS) propellant requirements during entry were investigated. It was determined that in the presence of a 3 sigma crosswind an addition
