Morphometrics is a multivariate technique for shape analysis widely employed in biological, medical, and paleoanthropological applications. Commonly used morphometric methods require analyzing a huge amount of variables for problems involving a large number of specimens or complex shapes. Moreover, the analysis results are sometimes difficult to in...

Fourier series are usually employed to describe closed or open, 2D or 3D outlines of biological samples. Landmark-based morphometric methods are widely used in the analysis of 3D surfaces. There are few investigations on the representation and morphometric analysis of 3D biological sample surfaces with methods relating to Fourier series. In this pa...

This paper presents a design methodology and experimental assessment of variable-geometry dies that enable the extrusion of plastic parts with a nonconstant cross section. These shape-changing dies can produce complex plastic components at higher manufacturing speeds and with lower tooling costs than injection molding. Planar, rigid-body, shape-cha...

A self‐oscillator is a flexible device capable of autonomously generating periodic oscillatory motion in response to a constant external stimulus. Limited by high damping forces in fluids, realizing self‐oscillatory with multiple degrees of freedom and high frequencies in fluids remains a great challenge. Here, a homogeneous Polypyrrole (PPy) and M...

The enantiospecific detection of the chirality of substances at the nanoscale has attracted significant attention due to its importance in materials science, chemistry, and biology. This study presents, to our knowledge, a novel method for chirality detection based on transverse optical torque (OT), which leverages the transverse rotation of achira...

Biological structures exhibit autonomous and intelligent behaviors, such as movement, perception, and responses to environmental changes, through dynamic interactions with their surroundings. Inspired by natural organisms, future soft robots are also advancing toward autonomy, sustainability, and interactivity. This review summarizes the latest ach...

MicroRNA (miRNA) in interstitial fluid (ISF) is a promising biomarker for early disease diagnosis, but its quantification is challenging due to low sampling efficiency and weak signals.

We propose an all-optical sorting method for chiral nanoparticles by use of a 3D-arbitrarily-oriented circularly polarized ultra-long optical needle field, which is constructed through reversing the radiation patterns from an array of spin dipole located in the focal volume of a 4Pi microscopy. It is demonstrated that particles with different chira...

High-performance microwave absorption (MA) materials must be studied immediately since electromagnetic pollution has become a problem that cannot be disregarded. A straightforward composite material, comprising hollow MXene spheres loaded with C–Co frameworks, was prepared to develop multiwalled carbon nanotubes (MWCNTs). A high impedance and suita...

Recently, the emergence of transverse orbital angular momentum (OAM) as a novel characteristic of light has captured substantial attention, and the significance of adjustable OAM orientation has been underscored due to its pivotal role in the interaction between light and matter. In this work, we introduce a novel approach to manipulate the orienta...

Ti3C2T x MXene has attracted widespread attention in lubrication owing to its unique structure and surface properties. However, the inferior nanotribological properties of Ti3C2T x still limit its applications in nano lubricants. Herein, we propose a controllable interface-tailored strategy to reduce the nanotribological properties of Ti3C2Tx by de...

With the rapid development of autonomous and intelligent devices driven by soft actuators, ion soft actuators in flexible intelligent devices have several advantages over other actuators, including their light weight, low voltage drive, large strain, good flexibility, fast response, etc. Traditional ionic polymer metal composites have received a lo...

Circular dichroism (CD) spectroscopy is a typical technique to detect the chirality of an object. Due to the mismatch between light wavelength and the size of molecules, CD signal generally tends to be very weak in natural materials. In this work, we demonstrate the generation of superchiral field in free space through multi-beam superposition, wit...

Predictable bending deformation, high cycle stability, and multimode complex motion have always been the goals pursued in the field of flexible robots.

Morphometrics is a quantitative analysis to compare a set of geometric representations of forms, including shape and size. Analysis of shape variation is useful in systematics, evolutionary biology, biostratigraphy, and developmental biology. Distinguished by the data being analyzed, three forms of morphometrics are commonly recognized. Traditional...

Any articulated system of rigid bodies defines a statically equivalent serial chain (SESC). The SESC is a virtual chain that terminates at the center of mass (CoM) of the original system of bodies. An SESC may be generated experimentally without knowing the mass, CoM, or length of each link in the system given that its joint angles and overall CoM...
