Abstract Recent research suggests that the effect of greenwashing and corporate financial performance (CFP) is ambiguous. This call for study the contextual factors that create contingencies in the greenwashing–CFP relationship. Using a sample of 2816 observations covering 735 Chinese‐listed firms in 21 different industries from 2013 to 2017, this ...

In this work, wide‐field (>1 mm2) frequency‐domain thermoreflectance (FDTR) hyperspectral imaging is used to image subsurface indium bump bonds 50 µm below the surface. Thermal analysis with Monte Carlo uncertainty propagation is used to evaluate bump quality, while a trained deep neural network (can rapidly reconstruct bump geometry contact area maps.

A variable stiffness structure with shape morphing and shape memory capabilities made from layered textiles and 3D printing material is developed. Direct printing of cPLA on textile electrodes maximizes the electrodes' contact area. This work presents a new method for achieving variable stiffness in small segments of soft, deformable structures, using ...

The active visual sensing methods for robotic welding: review, tutorial and prospect [PDF]
The visual sensing system is one of the most important parts of the welding robots to realize intelligent and autonomous welding. The active visual sensing methods have been widely adopted in robotic welding because of their higher accuracies compared to the passive visual sensing methods.

Functional Optical Fibers with Tailored Side Emission from Modified Rod‐in‐Tube Preforms
A modified rod‐in‐tube method enables fabrication of functional optical fibers with tailored light‐diffusing properties. The approach incorporates optically active species at a well‐defined radial position within an otherwise homogeneous fiber core. Using lanthanide ions and noble metal nanoparticles as active species demonstrates wavelength conversion

A reconfigurable microneedle electrode array integrated system is developed for minimally invasive and transdermal monitoring of subcutaneous electromyography, reactive oxygen species, and pH values. By assembling discrete thumbtack‐shaped microneedles into an array, the system enables multi‐parameter detection with single‐microneedle resolution.

Application Areas of Ionic Hydraulic Fluids
Ionic liquids as high‐tech technical fluids have also made their way into the field of hydraulic drives. With excellent lubricating properties, a wide temperature range, low pour point and vapor pressure, as well as nonflammability and environmental suitability, problems with only one type of fluid, namely, an ionic hydraulic fluid, instead of using ...
