Magnetic van der Waals (vdW) materials have emerged as promising candidates for spintronics applications, especially after the recent discovery of intrinsic ferromagnetism in monolayer vdW materials. There has been a critical need tunable ferromagnetic beyond room temperature. Here, we report real-space imaging study itinerant ferromagnet Fe3GeTe2 and enhancement its Curie temperature well above ambient We find that magnetic long-range order is characterized by an unconventional out-of-plane...
Polyolefins account for 60% of global plastic consumption, but many potential applications polyolefins require that their properties, such as compatibility with polar polymers, adhesion, gas permeability, and surface wetting, be improved. A strategy to overcome these deficiencies would involve the introduction functionalities onto polymer chain. Here, we describe Ni-catalyzed hydroxylation polyethylenes (LDPE, HDPE, LLDPE) in presence m CPBA an oxidant. Studies cycloalkanes pure, long-chain...
Abstract Over the past 70 years, semiconductor industry has undergone transformative changes, largely driven by miniaturization of devices and integration innovative structures materials. Two-dimensional (2D) materials like transition metal dichalcogenides (TMDs) graphene are pivotal in overcoming limitations silicon-based technologies, offering approaches transistor design functionality, enabling atomic-thin channel transistors monolithic 3D integration. We review important progress...
Chiral anomaly, a non-conservation of chiral charge pumped by the topological nontrivial gauge fields, has been predicted to exist in Weyl semimetals. However, until now, experimental signature this effect exclusively relies on observation negative longitudinal magnetoresistance at low temperatures. Here, we report field-modulated pumping process and valley diffusion Cd3As2. Apart from conventional magnetoresistance, observe an unusual nonlocal response with field dependence up room...
Borylation of aliphatic C-H bonds in alkylamines and alkyl ethers to form primary aminoalkyl alkoxyalkyl boronate esters studies on the origin regioselectivity these reactions are reported.

Selective borylation terminal bond at positions β oxygen nitrogen occurs preference other bonds. Experimental computational results show that cleavage is rate-determining step current...
Merons which are topologically equivalent to one-half of skyrmions can exist only in pairs or groups two-dimensional (2D) ferromagnetic (FM) systems.
