Abstract High levels of biodiversity and endemism in ancient lakes have motivated research on evolutionary processes in these systems. Drill-core records from Lake Titicaca (Bolivia, Peru), an ancient lake in the high-elevation Altiplano, record the history of climate, landscape dynamics, and diatom evolution. That re…
AIM: We studied externally controlled anticancer effects of binding tumor growth inhibiting synthetic peptides to magnetoelectric nanoparticles (MENs) on treatment of glioblastomas. METHODS: . Molecules of growth hormone-releasing hormone antagonist of the MIA class (MIA690) were chemically bound to MENs. In vitro exp…
This article reports the synthesis of cuprous oxide (Cu 2 O) and cupric oxide (CuO) nanowires by controlling the calcination environment of electrospun polymeric nanowires and their charge storage properties. The Cu 2 O nanowires showed higher surface area (86 m 2 g –1 ) and pore size than the CuO nanowires (36 m 2 g…
Amorphous calcium carbonate (ACC) is a metastable hydrated solid that has received great attention as a precursor in calcium carbonate crystallization in both synthetic and biological systems. In particular, the atomic structure of ACC is a matter of ongoing discussion. Some studies have pointed out similarities betwe…
Abstract The storage of metastable compounds and modifications of elements are of great interest for synthesis and other, e.g., semiconductor, applications. Whereas white phosphorus is a metastable modification that can be stored under certain conditions, storage of the extremely (light- and air-)sensitive form of ars…
Processing of materials at cryogenic temperature has improved the properties of materials such as hardness, toughness, wear resistance, tensile strength, dimensional stability, corrosion resistance, etc. However, the extent of improvement in the properties of materials subjected to cryogenic treatment as claimed in th…
Poly(ethylene succinate) (PES), poly(butylene succinate) (PBS), and poly(hexylene succinate) (PHS), were synthesized using succinic acid and different dihydric alcohols as materials. Enzymatic degradability by cutinase of the three kinds of polyesters was studied, as well as their solid-state properties. The biodegrad…
Tailored structural regulation to achieve novel compounds with special properties is very attractive and important for functional material design. In this paper, CsIO 3 was selected as a maternal structure and three new derivatives, namely, CsIO 2 F 2, Cs 3 (IO 2 F 2 ) 3 ·H 2 O, and Cs(IO 2 F 2 ) 2 ·H 5 O 2, were succ…
Colloidal silicon quantum dots (Si QDs) hold ever-growing promise for the development of novel optoelectronic devices such as light-emitting diodes (LEDs). Although it has been proposed that ligands at the surface of colloidal Si QDs may significantly impact the performance of LEDs based on colloidal Si QDs, little sy…
The aim of this article is to study the effects of functional groups such as hydroxyl, epoxide and carboxyl on the fracture toughness of graphene. These functional groups form the backbone of the intrinsic atomic structure of graphene oxide (GO). Molecular dynamics based simulations were performed in conjunction with…
Nanomaterials that show aggregation-induced emission (AIE) have tremendous potential in sensors, bioimaging, phototherapy and organic light-emitting diodes. Although big progress have been achieved in developing AIE nanomaterials and their applications, one downside of most previously described AIE nanomaterials is th…
Low-dimensional intrinsically ferromagnetic semiconductors are rare and crucial to develop the next-generation spintronics devices. CrI${}_{3}$ is a promising candidate since its ferromagnetism can be maintained upon exfoliating of bulk crystals down to single layer. However, the nature of magnetism in bulk CrI${}_{3}…
4-Nitrophenol (4-NP) is a priority pollutant in water and is both carcinogenic and genotoxic to humans and wildlife even at very low concentrations. Thus, we herein fabricated a novel molecularly imprinted core-shell nanohybrid as a ratiometric fluorescent sensor for the highly sensitive and selective detection of 4-N…
We report on experiments that consist in deforming a collection of monodisperse droplets produced by a microfluidic chip through a flow-focusing device. We show that a proper numerical modelling of the flow is necessary to access the stress applied by the latter on the droplet along its trajectory through the chip. Th…
The short range order in Ge 30 Ga 5 Sb 10 Se 55 and Ge 21 Ga 5 Sb 10 Se 64 glasses was investigated by X-ray (XRD) and neutron diffraction (ND) as well as extended X-ray absorption fine structure (EXAFS) measurements at the Ge, Ga, Sb and Se K-edges. Large scale structural models were obtained by fitting simultaneousl…
In two-dimensional (2D) semiconducting transition metal dichalcogenides (TMDs), new electronic phenomena such as tunable bandgaps1–3 and strongly bound excitons and trions emerge from strong many-body effects4–6, beyond the spin and valley degrees of freedom induced by spin–orbit coupling and by lattice symmetry 7 . C…
Single crystals of ${\mathrm{CrSbSe}}_{3}$, a structurally pseudo-one-dimensional ferromagnetic semiconductor, were grown using a high-temperature solution growth technique and were characterized by x-ray diffraction, anisotropic temperature- and field-dependent magnetization, temperature-dependent resistivity, and op…
The effective dimensionality of a semiconductor strongly influences its excitonic properties. Due to their unit-cell thickness, monolayer materials are the almost perfect realization of a two-dimensional system. However, the unit-cell dimensions can easily exceed the nominal value of the exciton Bohr radius. Employing…
We study the interplay of disorder and band-structure topology in a Weyl semimetal with a tilted conical spectrum around the Weyl points. The spectrum of particles is given by the eigenvalues of a non-Hermitian matrix, which contains contributions from a Weyl Hamiltonian and complex self-energy due to electron elastic…
We use a combination of Raman spectroscopy and transport measurements to study thin flakes of the type-II Weyl semimetal candidate $\mathrm{MoT}{\mathrm{e}}_{2}$ protected from oxidation. In contrast to bulk crystals, which undergo a phase transition from monoclinic to the inversion symmetry breaking, orthorhombic pha…
