Based on the normal-state electronic band structure, the necessary condition for a metal to become a superconductor is the simultaneous occurrence of flat and steep bands at the Fermi level. The sufficient condition at least for conventional superconductors is a strong enough coupling of the flat band states to the la…
Conflict of interest: the authors declare that they have no conflicts of interest. Methylchloroisothiazolinone/methylisothiazolinone (MCI/MI) (e.g. Kathon® CG; Dow Chemical Co., Midland, MI, USA) is a mixture of MCI and MI in a ratio of 3 : 1, currently used as a preservative in cosmetic, industrial and domestic produ…
We show that the existence of a sub-dominant form of dark matter, made of dark "antiatoms" of mass m ∼ 1 TeV and size 0 ∼ 3 fm, can explain the results of direct detection experiments, with a positive signal in DAMA/NaI and DAMA/LIBRA and no signal in other experiments. The signal comes from the binding of the dark an…
The effects of a selective AlN wet etchant, AZ400K, on the morphology and chemical composition of capped and uncapped GaN surfaces were investigated. After etching an uncapped GaN thin film at 80 °C for 8 h, the surface morphology was unchanged. After an annealing pulse of 1500 °C was applied, AlN-encapsulated GaN sur…
Graphene is fabricated by thermal decomposition of silicon carbide (SiC) and Pb islands are deposited by Pb flux in molecular beam epitaxy chamber. It is found that graphene domains and SiC buffer layer coexist. Selective growth of Pb islands on SiC buffer layer rather than on graphene domains is observed. It can be a…
In this work, we elucidate exciton structure, dynamics, and charge generation in the solution phase aggregates of a low-bandgap donor-acceptor polymer, poly(4,8-bis-alkyloxybenzo[1,2-b:4,5-b']dithiophene-2,6-diyl-alt-(alkylthieno[3,4-b]thiophene-2carboxylate)-2,6-diyl (PBDTTT). The polymer aggregates in the solution p…
A partially ordered Fe 16 N 2 thin film, which exhibits a higher saturation magnetization than a bcc-Fe thin film, was grown on a Au(001) texture on a GaAs(001) substrate for studies of crystalline structure, electronic structure, and magnetic properties. Fe 2p 3/2 and 2p 1/2 X-ray photoelectron spectroscopies (XPS) r…
The non-aggregational cyclo[6]aramide has demonstrated 2:1 host–guest complexation towards diquat with very strong binding ability (K1 = 5.41 × 104 M− 1, K2 = 4.33 × 106 M− 1). The donor–acceptor binding process of the macrocycle and the quaternary salt was investigated by 1H NMR, ESI mass spectrometry and UV–vis spec…
Malignant glioma are often fatal and pose a significant therapeutic challenge. Here we have employed α-helical right handed coiled coils (RHCC) which self-assemble into tetrameric nanotubes that stably associate with platinum (Pt) (IV) compound. This Pt(IV)-RHCC complex showed superior in vitro and in vivo toxicity in…
In Malaysia recently, it was found that cockle shell (Anadara granosa) is a potential source of biomaterial for bone repair. It is the most abundant sea species cultured in Malaysia. A possible advantage of using cockle shell as a biomaterial is that they may act as an antilog of calcium carbonate. Malaysian Nuclear A…
Low hygroscopicity is an important factor favoring the use of heat-treated wood materials. Hence, wild cherry (Cerasus avium (L.) Moench) wood was subjected to heat treatment with the ThermoWood® method for about 1 and 2 hours at temperatures of 190 and 212 °C in an industrial business. Then, trial samples were prepar…
A new series of linear–comb and 4-arm star–comb side chain liquid crystalline polymers (Lc-/Sc-SCLCPs) have been synthesized and characterized. The treatment of hydride siloxane-containing terminated liquid crystalline and high 1,2-/1,4- (high vinyl, hv/low vinyl, lv) linear or 4-arm star polybutadienes (L-/S-PBs) was…
Hydroxyapatite, (HAp), Ca10(PO4)6(OH)2, is recognised as biomaterial that widely used for orthopedics due to its similar to the inorganic component of human bone and enamel .The elements of HAp are primarily calcium and phosphorous, with a stoichiometric calcium to phosphorous ratio of 1.67 capable of promoting bone g…
In this work, original shock experiments are presented. Laser-induced shock and shear wave propagations have been observed in an epoxy resin, in the case of femtosecond laser irradiation. A specific time-resolved shadowgraphy setup has been developed using the photoelasticimetry principle to enhance the shear wave obs…
As a first step, we have synthesized and optically characterized a systematic series of one-dimensional (1D) single-crystalline Eu 3+ -activated alkaline-earth metal tungstate/molybdate solid-solution composite CaW 1– x Mo x O 4 (0 ≤ “ x ” ≤ 1) nanowires of controllable chemical composition using a modified template-d…
More stringent emission requirements for nonroad diesel engines introduced with U.S. Tier 4 Final and Euro Stage IV and V regulations have spurred the development of exhaust aftertreatment technologies. In this study, several aftertreatment configurations consisting of diesel oxidation catalysts (DOC), diesel particul…
Atomic charges are a key concept to give more insight into the electronic structure and chemical reactivity. The Hirshfeld-I partitioning scheme applied to the model protein human 2-cysteine peroxiredoxin thioredoxin peroxidase B is used to investigate how large a protein fragment needs to be in order to achieve conve…
Hydroxyapatite (HA, Ca 5 (PO 4 ) 3 OH) constitutes the inorganic component of bone. Its formation is regulated by noncollagenous proteins and especially negatively charged amino acids present in their structure. Here we show that Ca 2+ and PO 4 3– ions can interact with both a negative (Glu) and a positive (Arg) amino…
The paper is focused on the comparison between uniaxial and biaxial laboratory test results for polyester coated fabric. A short literature review concerning coated woven fabrics with emphasis on biaxial tensile tests is presented. A description of the polyester-coated fabric under biaxial test by means of constitutiv…
Multishell fullerenes, known as carbon nano-onions (CNOs), are an interesting class of carbon-based nanomaterials. They display several unique properties, such as a large surface area to volume ratio, a low density, and a graphitic multilayer morphology, which have made them appealing for several applications in many…
