Monolithic Integration of ScAlN Modulators on Silicon‐On‐Insulator Platform

Laser &Photonics Reviews, EarlyView.
Monolithic integration of scandium‐doped aluminum nitride (ScAlN) modulators on a silicon‐on‐insulator platform is reported. A multilayer electrode design enhances RF‐optical field overlap, enabling direct access to the diagonal electro‐optic coefficient and improved modulation efficiency.

Impact of Lithium‐Free Borate Additives on the Cycle Life and Calendar Aging of Silicon‐Based Lithium‐Ion Batteries [PDF]

Small Sci
Borate additive mechanisms for enhanced electrolyte stability and solid electrolyte interphase (SEI) formation: a) Additives act as anion receptors, mitigating [PF6]− decomposition. b) Additives decompose, contributing to a boron‐, lithium‐, and oxygen‐rich SEI. Silicon‐anode lithium‐ion batteries (LIBs) suffer from limited cycle life and poor calendar

Social, Technological, Economic, and Policy Factors in the Circular Economy Transition in Brazil

Sustainable Development, EarlyView.
ABSTRACT A well‐functioning circular economy (CE) integrates resilience across economic, environmental, and social dimensions. This study identifies key drivers and barriers to Brazil's CE transition through 20 semi‐structured interviews with stakeholders. Major sociocultural barriers include inadequate education and limited CE awareness, while growing

Chemically‐Linked Heterostructures of Palladium Nanosheets and 2H‐MoS2

Small, EarlyView.
The photoresponse of MoS2 devices is extended to the near‐infrared region (up to 1700 nm) through chemical connection to Pd nanosheets (PdNS). A maleimide is used for covalent connection to MoS2, and a phenyl bromide moiety for linkage to the PdNS. In the absence of the chemical linker, van der Waals heterostructures show poorer enhancement of the ...
