Enhancing the Ultrasonic Welding of Wood Using 3D Printed Lignin Energy Directors

Advanced Science, Volume 13, Issue 15, 13 March 2026.
Sustainable manufacturing for lightweight structures using ecofriendly materials will be key to reducing material consumption and lowering carbon footprints. Here, an approach is presented to weld wood using ultrasonic vibrations with material at the joint interface to direct energy.

Atomistic Understanding of 2D Monatomic Phase‐Change Material for Non‐Volatile Optical Applications

Advanced Science, Volume 13, Issue 16, 18 March 2026.
Antimony is a promising monatomic phase‐change material. Scaling down the film thickness is necessary to prolong the amorphous‐state lifetime, but it alters the optical properties. The combined computational and experimental study shows that, as thickness decreases, the extinction coefficient and optical contrast are reduced in the near‐infrared ...

Synaptic Behavior in SnSe2 Field‐Effect Transistors Induced by Surface Oxide and Trap Dynamics

Advanced Electronic Materials, Volume 12, Issue 5, 9 March 2026.
Multilayer SnSe2 field‐effect transistors display gate‐tunable optoelectronic plasticity driven by interfacial trap states. Persistent photocurrent is reversibly tuned between short‐ and long‐term memory through gate bias and pulsed control. The devices emulate synaptic functions such as potentiation, modulation, and cumulative learning, establishing ...

Bio‐Inspired Cascade Photocatalysis on Fe Single‐Atom Carbon Nitride Upcycles Plastic Wastes for Effective Acetic Acid Production

Advanced Energy Materials, Volume 16, Issue 9, 4 March 2026.
This work demonstrates a novel cascade photocatalysis concept using Fe single‐atom catalysts (Fe@C3N4 SAC) to directly upcycle plastics (PET, PP, PE, PVC) into valuable acetic acid at ambient conditions. Inspired by microbial degradation, the bifunctional cascade photocatalyst combines Fenton‐like oxidation and CO2 photoreduction, as validated by ...

Automatic quality assessment of terrestrial laser scans

Journal of Applied Geodesy, 2023
Abstract This work addresses the topic of a quality modelling of terrestrial laser scans, including different quality measures such as precision, systematic deviations in distance measurement and completeness. For this purpose, the term “quality” is first defined in more detail in the field of TLS.

Terrestrial Laser Scanning

2011
Since the early 2000s terrestrial laser scanning has evolved from a research and development (R&D) topic to a geo-data technology, which is commercially offered by a multitude of land surveying companies and other service providers all over the world. The technology is primarily used for the rapid acquisition of three-dimensional (3D) information of a ...

Basics of Terrestrial Laser Scanning

2019
This chapter introduces the basic concepts of the automatic 3D surveying by means of laser scanning techniques, a methodology developed less than 20 years ago (see, e.g., Boehler et al. 2002) thanks to the technological improvement of the topographical instrumentations, in particular in the movement and in the electronical components.

Individual tree biomass estimation using terrestrial laser scanning

ISPRS Journal of Photogrammetry and Remote Sensing, 2013
Abstract Determination of stem and crown biomass requires accurate measurements of individual tree stem, bark, branch and needles. These measurements are time-consuming especially for mature trees. Accurate field measurements can be done only in a destructive manner.
