Nanostructured catalysts often face an important challenge: poor stability. Many factors contribute to catalytic degradation, including parasitic chemical reactions, phase separation, agglomeration, and dissolution, leading activity loss especially during long-term reactions. This challenge is shared by a new family of catalysts, multimetallic nanoparticles, which have emerged owing their broad tunability high activity. While significant synthesis-based advances been made, the stability...
The incompatibility between the anode and cathode chemistry limits used of Mg as an anode. This issue may be addressed by separating anolyte catholyte with a membrane that only allows for Mg2+ transport. Mg-MOF-74 thin films were separator this purpose. It was shown to meet needs low-resistance, selective uniform MOF supported on Au substrate thicknesses down ca. 202 nm showed intrinsic resistance low 6.4 Ω cm2 , normalized room-temperature ionic conductivity 3.17×10-6 S cm-1 . When...
Abstract Lithium metal anode holds great promises for next‐generation battery technologies but is notoriously difficult to work with. The key solving this challenge believed lie in the ability of forming stable solid‐electrolyte interphase (SEI) layers. To further address potential safety issues, it critical achieve goal nonflammable electrolytes. Building upon previous successes SEI conventional carbonate‐based electrolytes, here we report that reversible Li stripping/plating could be...
Abstract Bayberry ( Myrica rubra Sieb. et Zucc.) kernel is a by‐products of bayberry processing and are rich in oil. This study investigates the effects different methods on oil (BKO) yield, including cold pressing (CP), direct solvent n ‐hexane) extraction, ultrasound‐assisted ‐hexane extraction (UAE), steam explosion pretreatment to assist aqueous enzyme supercritical fluid (SFE). The acid value, peroxide fatty composition, bioactive components content, antioxidant activity extracted BKO...
Abstract A dual polarization perfect absorber based on hexagonal boron nitride (hBN) crystals within the mid-infrared (M-IR) spectral regime has been displayed numerically. The newly developed comprises hBN film applied a substrate, with spacer layer between and series of dielectric square arrays. nearly 100% polarization-insensitive absorption at 6.9515 μm for light under normal incidence, related to guided mode resonance effect. Such is interpreted physically by examining electromagnetic...
This paper presents a systematic benchmarking comparison between optimal motion planners. Six planners representing the categories of sampling-based, grid-based, and trajectory optimization methods are compared on synthetic problems varying dimensionality, number homotopy classes, width length narrow passages. Performance statistics gathered success convergence rates, performance variations with respect to geometric characteristics analyzed. Based this analysis, we recommend that likely...
The problems of low discharge voltage and poor rechargeability for Mg–O<sub>2</sub> batteries can be addressed by using two redox mediators.
This paper presents an autonomous planning and control framework for humanoid robots to climb general ladder- stair-like structures. The approach consists of two major components: 1) a multi-limbed locomotion planner that takes as input ladder model automatically generates whole-body climbing trajectory satisfies contact, collision, torque limit constraints; 2) compliance controller which allows the robot tolerate errors from sensing, calibration, execution. Simulations demonstrate is...
This video presents our preliminary work towards addressing the ladder climbing event in DARPA Robotics Challenge (DRC) using DRC-Hubo robot. A ladder-climbing motion planner is developed which generates a collision-free, stable quasi-static trajectory for execution. Compliance control enabled on arm joints to compensate calibration error, modeling error and error. We have demonstrated that can robustly climb variety of ladders simulation successfully ship hardware.
Optimization is often difficult to apply robots due the presence of modeling errors, which may cause constraints be violated during execution on a real robot.This work presents method optimize trajectories with large errors using combination robust optimization and parameter learning.In particular it considers problem computing dynamically-feasible trajectory along fixed path under frictional contact, where friction uncertain actuator effort noisy.It introduces time-scaling that able accept...
This paper describes preliminary steps toward providing the Hubo-II+ humanoid robot with ladder climbing capabilities. Ladder is an essential mode of locomotion for navigating industrial environments and conducting maintenance tasks in buildings, trees, other man-made structures (e.g., utility poles). Although seemingly straightforward humans, this task quite challenging robots due to differences from human kinematics, significant physical stresses, simultaneous coordination four limbs...
This paper presents a method for generating dynamically-feasible, natural-looking robot motion from freehand sketches. Using trajectory optimization, it handles sketches that are too fast, jerky, or pass out of reach by enforcing the constraints robot's dynamic limitations while minimizing relative temporal differences between and sketch. To make optimization fast enough interactive use, variety enhancements employed including decoupling geometric optimizations methods to select good initial...
This paper presents a Monte Carlo technique for sampling configurations of kinematic chain according to specified probability density while accounting loop closure constraints. A key contribution is method sub-loops in unbiased fashion using analytical inverse kinematics techniques. Sub-loops are then iterated across the produce samples entire chain. The demonstrated scale well high-dimensional chains (>200DOFs) and applied flexible 2D chains, protein molecules, robots with multiple closed-chains.
Dynamic manipulations require attaining high velocities at specified configurations, all the while obeying geometric and dynamic constraints. This paper presents a motion planner that constructs trajectory passes an intermediate state through objective region, which is comprised of certain lower dimensional submanifold in configuration/velocity space, then returns to rest. Planning speed reliability are greatly improved by finding good states first, because choice couples ramp-up ramp-down...

Reentrant loops are an important structure motif in a-helical transmembrane proteins. A reentrant loop goes half way through the membrane and turns exits same side it has entered. To better predict topology of proteins understand their function, is to investigate why form such a unique topology. Herein, we compare with helices find that two types motifs differ significantly residue composition difference reside sufficient discriminate from based on amino acid sequence.
