Published: September 2022

Nowadays 3Cr13 martensitic stainless steel is increasingly used for precision molds. However, its low-temperature impact toughness below room temperature requires further improvement. This study investigates the effect of heat treatment process of a Ni-containing at low temperature impact toughness of 3Cr13 stainless steel used for precision die. Various characterization techniques are combined in order to unveil different heat treatment processes on impact toughness. The test results show that after three different heat treatment processes, the low-temperature impact toughness of the investigated steel at 0 ℃ has been greatly improved. After the investigated steel is heated at 1040 ℃ for 15 minutes, then water-cooled quenched, and then heated to 540 ℃ for 30 minutes, the impact fracture is a dimple shaped plastic one, and its low-temperature impact absorbed energy is higher than that of other heat treatment processes. It shows that the holding time under quenching heating temperature and tempering temperature also have important effects on the improvement of low-temperature impact toughness, which provides technical support for heat treatment design for the Ni-alloyed 3Cr13martensitic stainless steel.

Published: September 2022

Background: An auditory-oral approach can help deaf children achieve success in
oral communication. Many studies confirm that deaf children with access to sound through
high-powered and appropriate hearing aids at the youngest age possible have the
capability to acquire communication skills similar to their hearing peers.
Objective: Evaluate the listening and speaking progress made by 27 Thai hearing-impaired
children who attended a preschool aural rehabilitation program, which was established at
Audiology and Speech clinic. After hearing aids fitting, deaf children were enrolled to
the preschool aural rehabilitation program after receiving their parents consent.
Material and Method: Hearing impaired children were divided into groups of 4-6 children
with approximately the same level of performance. The listening and speaking performance
at the initial period were recorded. Each group participated in the 3-hourprogram once a
week, included auditory training, conversation (maternal reflexive method), and speech
stimulation. The improvements and problems of each child were recorded at the end of
session. Listening and speaking performance evaluation were recorded at six months
intervals. Results: There were 12 boys and 15 girls. The average hearing loss in
the better ear was 104 dBHL, range from 83-117 dBHL, SD = 8.33. The mean age of
enrollment was 2 years and 10 months. The majority gradually developed listening skills
and speaking ability. There was no relationship between age of enrollment and the
listening and speaking ability (p > 0.05). However, listening skills had positive
relationship with length of speech (r = 0.685), number of spoken vocabulary (r = 0.665),
and speech character (r = 0.598); p < 0.01. Conclusion: Auditory training is an
important task to develop listening skills and improve length of speech, speaking
vocabulary, and speech character. Other benefits from the aural rehabilitation program
included monitoring the auditory progression after hearing aid fitting, parents meeting,
and promotion a better quality of life by enabling hearing impaired children to
participate in hearing society. Published courtesy of: J Med Assoc Thai. 2010;

Published: September 2022

The purpose of this study was to investigate the prevalence and etiology of
hearing loss in primary and middle school students in the Hubei province of China.
During a 2-year period, 504,348 students were examined by a speech audiometry test, and
813 deaf students were detected. Among the 813 deaf students, 232 cases were diagnosed
with congenital deafness and 560 cases had acquired deafness, among which 276 cases had
aminoglycoside-antibiotic-induced deafness. The severity of deafness could be further
ascertained in 804 other students, with 402 profound, 363 severe, 21 moderate and 18
mild deafness cases. The age at deafness onset of most students was under 3 years. The
prevalence of congenital and acquired deafness was 0.046% (232/504,348) and 0.111%
(560/504,348), respectively, much lower than previously reported in other regions of
China. Furthermore, the genetic factor was identified as one of the principal causes of
deafness by pedigree analysis. Published courtesy of: Audiol Neurootol. 2010;

<p>Universal newborn hearing screening in Singapore: the need, implementation
and challenges</p>
Authors: Low W K , Pang K Y , Ho L Y , Lim S B , Joseph R 
Published: September 2022

With about 1 in 1000 born with severe to profound hearing loss and about 5 in 1000
with lesser degrees of loss, congenital deafness is the commonest major birth defect. It
is the recommended standard that hearing loss in newborns be detected by 3 months of age
and intervention implemented by 6 months of age. Delayed detection and intervention may
affect speech, language and psychosocial development, resulting in poor academic
achievements. Universal newborn hearing screening (UNHS) is the only effective way of
detecting all babies with hearing loss, within the recommended time frame. A survey in
Singapore revealed that traditional childhood hearing screening programmes resulted in
late detection (mean age, 20.8 months; range, 0 to 86 months) and late intervention
(mean age, 42.4 months; range, 1 to 120 months). Increasingly, UNHS is becoming standard
medical care in developed countries. In Singapore, UNHS has been implemented in all
hospitals with obstetric services. Although a screening rate of more than 99% has been
achieved in public hospitals, private hospitals have a screening rate of only about 77%.
Parents' awareness and acceptance of early detection is still lacking, and this needs to
be addressed by appropriate public education. Support from obstetricians and
paediatricians will significantly contribute towards this objective. Effective programme
management is essential; this includes the use of data management systems, the
maintenance of a team of experienced screeners, and efficient coordination between
screening and diagnostic services. Early detection of childhood deafness, together with
early and effective intervention, maximises the chances of successful integration into
mainstream education and society. Published courtesy of:Ann Acad Med Singapore.

Going-Concern Audit Opinion and Firm-Specific Expertise of Outsourced IAF Providers: Empirical Evidence from an Emerging Market
Authors: Omer Waddah Kamal Hassan 
Published: September 2022

Objective and interest of the work: This study examines the effect of firm-specific expertise of outsourced IAF providers on going-concern audit opinion.
Design of the methodology: Based on the agency theoretical background as well as relevant studies from the audit literature, the study’s hypothesis is developed and tested by probit regression to analyse the data of 1,071 firm-year observations listed on the Omani capital market over the period 2006-2019.
Results: The result is consistent with the hypothesis that Omani public listed companies with greater reliance on the outsourced IAF providers who have sufficient firm-specific expertise are less likely to receive a going-concern audit opinion.
Practical implications: The current study reinforces theoretical and practical implications for regulators, auditors, shareholders and decision makers by providing the first empirical evidence on the relationship between the firm-specific expertise of outsourced IAF providers and going-concern audit opinion, in an Asian emerging market, specifically Omani, context.

Published: September 2022

AbstractMicrovascular dysfunction caused by hyperglycemia leads to slow healing of diabetic wounds and significantly increases the risk of bacterial infection. The misuse of antibiotics can also lead to bacterial resistance, making the management of diabetic wounds more challenging. Thus, developing new antibacterial agents or strategies to overcome antibiotic resistance is highly pursued. Herein, novel supramolecular photothermal nanoparticles (MCC/CS NPs), assembled from mono‐carboxyl corrole (MCC) and chitosan via hydrogen bonding and π–π stacking, are developed and used for treating bacterial wound infection. The MCC molecules possess good photothermal performance and the chitosan with inherent bioactivity can exert moderate antibacterial effects. The aggregation of MCC in MCC/CS NPs induced by chitosan‐templated self‐assembly further quenches molecular fluorescence and realizes an extraordinary photothermal conversion efficiency of 66.4%. Moreover, the highly positively charged MCC/CS NPs can selectively target bacteria via electrostatic interactions. Under near‐infrared laser irradiation, the MCC/CS NPs achieve potent photothermal and inherent antimicrobial synergistic effects against Escherichia coli and methicillin‐resistant Staphylococcus aureus (MRSA) in vitro. Furthermore, the bacteria‐infected diabetic wound model confirms that the MCC/CS NPs can effectively kill drug‐resistant bacteria, accelerate wound healing and angiogenesis, and show good biocompatibility, representing a novel and efficient photothermal antibacterial nanoplatform.

Published: September 2022

AbstractBioresorbable stents (BRS) hold great promise for the treatment of many life‐threatening luminal diseases. Tracking and monitoring of stents in vivo is critical for avoiding their malposition and inadequate expansion, which often leads to complications and stent failure. However, obtaining high X‐ray visibility of polymeric BRS has been challenging because of their intrinsic radiolucency. This study demonstrates the use of photopolymerization‐based 3D printing technique to fabricate radiopaque BRS by incorporating iodixanol, a clinical contrast agent, into a bioresorbable citrate‐based polymer ink. The successful volumetric dispersion of the iodixanol through the 3D‐printing process confers strong X‐ray visibility of the produced BRS. Following in vitro degradation, the 3D‐printed BRS embedded in chicken muscle maintains high X‐ray visibility for at least 4 weeks. Importantly, the 3D‐printed radiopaque BRS demonstrates good cytocompatibility and strong mechanical competence in crimping and expansion, which is essential for minimally invasive stent deployment. In addition, it is found that higher loading concentrations of iodixanol, e.g. 10 wt.%, results in more strut fractures in stent crimping and expansion. To conclude, this study introduces a facile strategy to fabricate radiopaque BRS through the incorporation of iodixanol in the 3D printing process, which could potentially increase the clinical success of BRS.
An Artificial Interphase Engineering Simultaneously Suppressing Hydrogen Evolution Reaction and Controlling Zinc Dendrite Growth to Achieve Stable Zinc Metal Anodes

Published: September 2022

AbstractZinc metal anode, the most promising candidate material for rechargeable aqueous zinc‐ion batteries, has attracted considerable attention due to its abundant resources and low cost. However, hydrogen evolution reaction and uncontrollable zinc dendrite growth on zinc metal anode are the essential issues that strictly limit their practical application. Here, a modified Zn with a titanium nitride (TiN) protective layer (TiN@Zn) using a simple solvent casting approach is developed, which can simultaneously suppress the hydrogen evolution reaction and control the zinc dendrite growth when acting like a protective layer on the Zn anode. In situ differential electrochemical mass spectrometry approach shows that the TiN coating layer can effectively suppress the hydrogen evolution. Additionally, the TiN can offer large Zn nucleation sites, narrowing the Zn nucleation energy barrier, leading to a uniform Zn deposition. Thus, in symmetric cells, the TiN@Zn electrode presents a stable Zn plating/striping (600 h at 1 mA cm−2) and lower potential hysteresis (38 mV), resulting in an improved electrochemical performance for TiN@Zn||MnO2 full cell.

AbstractPhotocatalytic hydrogen production is a prospective technology to solve the energy crisis and environmental problems. However, it is still challenging to produce hydrogen from photocatalytic water splitting on a large scale without a sacrificial agent and cocatalyst. Here, it is demonstrated that the dual doping of Ru/In single atoms on TiO2 (Ru‐In SA/TiO2) can modulate the separation of photogenerated carriers during the photocatalytic splitting of pure water. Impressively, the H2 evolution rate of Ru‐In SA/TiO2 reaches 174.1 µmol h−1, which is 6, 18, and 53 times higher than those of the Ru single‐atom decorated TiO2, In single‐atom decorated TiO2, and pristine TiO2, respectively. More importantly, Ru‐In SA/TiO2 outperforms most of the reported photocatalysts for photocatalytic water splitting in the absence of a sacrificial agent. Detailed investigations reveal that the decoration of Ru/In dual‐single atoms leads to the remarkable increase of Ti3+ and enrichment of oxygen vacancies, which accelerate the charge separation. In particular, the femtosecond transient absorption spectroscopy suggests that the doping of Ru single atom promotes the transfer of photogenerated electrons from TiO2 into Ru, while the doping of In single atom enhances the transfer of photogenerated holes from the TiO2 valence band to In single atoms, as a result of an efficient electron‐hole separation. This work not only provides an efficient photocatalyst for H2 production through pure water splitting in the absence of a sacrificial agent, but also promotes fundamental research on catalyst design and modification.

Published: September 2022

AbstractImproving the performance of polyurethane is a crucial endeavor due to its versatile properties that make it suitable for various uses, especially as a matrix in the field of composite materials. The current work investigates the influence of the addition of two types of graphene derivatives, graphene oxide (GO) and reduced graphene oxide (rGO), to hard copolymer polyurethane (HCPU). HCPUs as nanocomposites were synthesized using melt‐mixing approaches with different weight ratios of nanofiller additives. The transmission electron microscopy and scanning electron microscopy displayed the morphology through the incorporation of nanofillers within the HCPU structure. Thermogravimetric analysis (TGA) testing showed an increase in the thermal stability of HCPU with the addition of GO and rGO. Herein, the overall HCPU crystallinity/microphase separation decreased after the addition of GO and rGO compared to unfilled HCPU samples. The thermal stability test showed significant enhancement with increasing GO and rGO incorporated weight ratio due to the barrier and tortuous path effects of nanofillers. A clear increase in thermal and electrical conductivity is found, in particular at greater content of addition (5 wt%) of rGO in comparison with neat HCPU. The rheological behavior showed that the storage modulus of HCPU nanocomposites increased from that of pure HCPU, proving the formation of a filler‐polymer network interaction within the HCPU chain structure. Dispersion and physical and/or chemical interaction of the GO and rGO within polyurethane chains plays a major role in enhancing the morphology and thermal and rheological properties, and thus represents a significant improvement for the final properties of HCPU nanocomposites.
